–How to select the most appropriate test chamber for the battery test application.
–Safety Features and Precautions
Epec Engineered Technologies manufactures custom cables for specific applications based upon customer design and print requirements. We can assist with cable and connector selection, layout and manufacturing techniques, and computer aided design (CAD).
Critical flex and rigid-flex circuit applications often must pass very stringent electromagnetic (EM) or radio frequency (RF) interference requirements. This type of interference, if absorbed or emitted, can negatively impact the functionality and reliability of the end product when in use.
To prevent this from occurring, the circuit design must incorporate shielding to eliminate either the absorption or transmission of EM or RF interference. For flex and rigid-flex PCB designs, there are two types of shielding solutions that can be applied, but which is best suited will depend upon other design requirements.
In this webinar, we review shielding methods and how to implement them in a flex or rigid-flex PCB design to ensure interference free operation of your design.
For more information on our custom flex and rigid-flex circuit solutions, visit https://www.epectec.com/flex.
Medical Flex and Rigid-Flex circuit applications require that the design provides the utmost in reliability. Unique combinations of electrical requirements, mechanical bend requirements, and in some cases medical operating environments, require careful and thorough design review.
In this webinar we will cover how these requirements interact and what their impact on circuitry layout, materials, and the construction of the design are.

Cable Certification - Six Reasons It Is More Important Than EverFluke Networks
The most thorough testing for network cabling is certification. Certification proves that a cabling system adheres to rigorous
standards for performance and installation workmanship. Cable certification requires trained technicians and specialized
test equipment.
Historically, chemical fuses have been used to disable the battery in the event that the secondary safety becomes active. Many of these fuse manufactures do not support medical applications or their fuses are too small to use in very high-current applications.
This webinar will discuss using FETs in secondary protection applications, which have many advantages over using chemical fuses from multi sourcing to full medical application support, and potential to lower cost depending on the application.
Additionally exploring latching and non-latching applications and how to implement them and integrate them with popular safety circuits in wide use today.

China has a rapidly developing submarine cable system manufacturing industry which operates in a healthy competitive manner. Subsea cables can fall into several different system product streams including relatively standard products for long haul telecoms projects (the subject of this paper) and customised products for the Oil & Gas, Scientific Observation Systems, Defence applications and HV subsea cables. While much of the Telecoms product has been sold in the domestic market, Hengtong Marine has broken into the International Market by addressing client concerns over quality and now has a track record for deployed overseas systems. This has been achieved in part by completing an offshore cable system sea trial, which is a requirement of the cable system qualification to ITU-T G-976 & ITU-T G.972 standards. The requirement for a sea trial is a barrier which every cable system producer has to address to achieve international sales. Hengtong Marine is moving forward to promote and improve the image of “Global Quality from China”.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. EXECUTIVE SUMMARY
Published in collaboration by LEMO and Northwire, this
white paper represents the first in a series focused on
the critical to quality requirements of connector and
cable assembly applications in extreme environments.
Ranging from underwater to oil and gas, the series will
address key specifications that are as diverse as their
markets. Since more than 71% of the earth’s surface is
covered by water, it is no surprise that there are an
abundance of application failures associated with this
dominant element. To ensure your success, rely on our
subject matter experts to improve your risk assessment
of off-the-shelf parts, learn how custom designs improve
protection, and navigate complex environmental factors.

4. Total Cost of Ownership
Avoid the inherent hazards of a narrow-minded bottom line focus
Sometimes focusing on hurdle rates, internal rate of return, and the short-sighted bottom
line can lead to disaster. This is often the case when making “apples to oranges”
comparisons. While engineered products can have a marginally higher price vs. off-the-shelf
parts and appear more attractive initially, it is vital to be aware of the longer-term
hidden dangers of decision-making based on price alone. There are actually 29 cost
factors to consider, including service quality, risk management, total landed cost, labor,
training, and much more.
The importance of specifying products based upon quantitative critical-to-quality
requirements cannot be over-stressed. Price alone cannot be the deciding factor;
decision-makers should evaluate subject matter expertise, domestic and international
standards, agency compliance, environmental regulations, and electrical, mechanical,
ergonomic, aesthetic, harsh duty, and end-user requirements to name a few.
Third-party testing will add assurance to an “apples to apples” comparison. Make sure an
independent Nationally Recognized Testing Laboratory (NRTL) certifies to the standards
of IP68, CE Mark, UL, CSA, cUL, CE, MSHA, NFPA, ABS, USCG, IEEE, SAE and more
as appropriate.
Employ additional selection criteria to avoid the pitfalls of expensive lessons from judging
apples and oranges by the same criteria:
Cheap alternatives could create:
3
• Safety Issues
• Equipment Damage
• Productivity Downtime
• Loss of Revenue
• Reputation Harm
Be sure to research:
• Are the products counterfeit?
• Are the copper bases identical (e.g.,
$4.14 vs. $3.82)?
• Is the copper quality similar?
• Are the combination of approvals
possible?
5. Expensive Lessons Learned
When cheap commodities cost a lot
When it comes to spectacular displays and incredible entertainment, few places rival the
casino. A huge amount of work goes into powering, programming, controlling, and
maintaining the shows and attractions seen at these sites.
In 2011, a contractor at one of the world’s largest casinos contacted Northwire. One of
the large underwater entertainment venues at the facility, a water theater housing a
multimillion dollar production, experienced massive destruction due to an underwater
cable system that failed to properly block water – resulting in an equipment loss to the
tune of $250,000 USD.
The original cable assembly was designed to control and power water jets, lighting,
moving platforms, and more as directed by a central control computer. When the
system broke down, it was not only unsuccessful in stopping water leaks, but siphoned
water back into the central control computers. In addition to the equipment damage, all
operations had to be shut down in the venue.
As with this contractor, many project managers struggle to find reliable cable and
connectors for underwater use. Another layer of factors comes into play when mixing
electronics and liquids, so precision, quality, and safety are of the utmost importance.
Avoid liquidated damages associated with commodity parts that are not
engineered and designed to meet the exact function!
4
6. 5
Fit vs. Function
Custom designs for your protection
From time to time a standard part is installed and
operates without obvious problems. This short-term “fit”
can have defects that are hard to detect, like inferior
materials or manufacturing non-conformances. While
not immediate, selecting products on “fit” alone
increases the likelihood of early failure. Custom
engineered OEM solutions, on the other hand, are
designed to meet exact product specifications, ensuring
that both fit and function are achieved. And, they are
tested and field-proven to the identical application and
subjected to their intended life cycle.
One size does NOT fit all
With the diverse range of underwater applications, there truly is no “one size fits all”
cable assembly system. When a customer comes to LEMO or Northwire with a project
in mind, the goal is to find the most effective connector or cable or cable assembly for
that specific use.
Therefore, no off-the-shelf product is standardized for underwater applications. Instead,
a customer will meet with a subject matter expert to discuss the challenges and
requirements of each individual project. Working closely with the customer, the experts
employ rapid prototyping and testing capabilities to design and manufacture each
component to the customer’s needs.
Northwire met with the casino’s contractor and identified
the root cause of the failure. Meanwhile, the team
gathered all of the critical-to-quality requirements from
key stakeholders. Then, NWI’s subject matter experts
rapidly designed, tested, and prototyped a cable
specifically for the venue’s rugged requirements. The
custom cable system was tested to withstand 100 PSI
(6.985 bar) and delivered high performance when fully
submersed in chlorinated water. Reinforced tensile
strength, abrasion resistance, and flexibility enabled the
cable to wrap around concrete pylons while preserving
signal integrity.
7. Solution-oriented and application-driven, the cable and connector design, engineering,
and manufacturing processes all become tailored for the individual project, giving
customers a best quality, highly effective, long lasting system.
LEMO’s Cable Connectors are designed and tested to exact specifications
From shallow waters to ocean depths of 1000 meters (3280 feet), LEMO’s precisely
manufactured watertight connectors have been the answer for clients across the world.
With a guaranteed IP68 rating, the line of shallow-use connectors is built off LEMO’s
pioneering Push-Pull connection system that has been perfected over the last six
decades. The manufacturer’s line for deep sea connectors, also called high pressure
connectors, are based on a screw coupling design. Both lines can be made with
chrome-plated brass or stainless steel materials, chosen as appropriate for the length of
immersion and risk of corrosion or oxidation.
LEMO’s primary connector lines for underwater use consist of the V Series, W Series,
and 03 Series:
• V Series. Available in multiple contact types, including coaxial, triaxial, and
multipole, these connectors perform in pressures up to 30 bar (435.11 PSI).
• W Series. Also for pressures up to 30 bar (435.11 PSI), the W Series is designed
for multipole and fiber optics contact configurations.
• 03 Series. This small connector has been tested for extensive salt spray
corrosion resistance up to 1000 hours. Additionally, the 03 Series is tested for
depths of 1200 meters (3937 feet) and high voltage for absolute waterproofing to
ensure a reliable, high performing connection.
6
8. These connector series are ideal for applications
from underwater cameras and telecommunications to
unmanned submersibles and bathyscaphes. For
example, LEMO connectors can be found in the
Delphin 2 Autonomous Underwater Vehicle created
for subsea environments by the University of
Southampton (UK).
Additionally, the leading quality of LEMO connectors
enables these components to meet and exceed the
requirements of critical applications such as sea wind
power, offshore oil rigs, oceanographic science, and
military defense systems.
Environmental Factors
The wide variety of environmental factors drives the broad scope and need for high-quality
connectors and cable assemblies’ precision engineered and designed for
underwater applications. Field-proven, LEMO and Northwire address challenges in
nearly limitless industries and functions beyond the entertainment world, such as:
7
• Offshore or fixed oil rigs
• Fixed or floating offshore structures
• Underwater lighting
• Inspection and monitoring
• Vision systems
• American Bureau of Shipping (ABS)
• United States Coast Guard (USCG)
• Marine Shipboard
• Umbilical cables
• Sensors and transducers
• Buoy systems
• Fishing equipment
• Tracking and locators
• Military and marine
• Aquatic research
• Industrial water systems
9. Critical-to-Quality Factors
When evaluating underwater cable systems, consider these critical-to-quality factors:
1. Application. Underwater vision systems may require a fundamentally different
type of cable than underwater lighting or monitoring and research applications.
2. Compliance. Ratings, agency listings, government certifications and
environmental standards: UL, ANSI, CSA, CE, IEEE, ABS, RoHS2, REACH,
and 1,000 hour weatherometer requirement.
3. Features. Signal, control, instrumentation and power.
4. Water Type. Different options exist for salt, fresh, brackish, chemical-treated,
waste, and potable water. For example, cable in contact with potable water
may need to be made of FDA-approved, food-grade materials.
5. Cable Depth. Cable systems at greater depths require heavy-duty materials
and pressure resistance. NWI’s underwater cable capabilities extend to a
depth of 30 meters (98.43 feet).
6. Flex. Cold bend, torsional, rolling, variable, bend, and continuous flex options
exist for cables whose applications require regular motion.
7. Environment. Knowing whether a cable must function in an industrial pipe,
ocean, or rocky riverbed determines many design factors.
8. Temperatures. From Arctic to high rating, cable systems are designed for

specific temperatures ranges.
9. Buoyancy. Special considerations must be taken when a cable is required to
have a negative, neutral, or positive buoyancy.

projects, Northwire has an answer.
Unique Designs for Your Protection
One of the most important factors when designing and manufacturing underwater
cables and connectors is the level of water resistance. Beyond basic protection to keep
the system from damage, there must be an intrinsically safe measure in play. In the
case of the casino, when the first degree of protection failed, the compromised cable
acted as a hose, syphoning the leak efficiently and directly to the control center.
In order to ensure absolutely watertight components in a variety of uses, LEMO and
Northwire use top-quality materials with purposeful design.

11. For cable systems, a choice of water-blocking conductors, tapes, and fillers work to not
only prevent leaks, but to create a barrier in case of cut, abrasion, or severe damage.
Unlike many cable assemblies, which use a gel filler as a barrier for the first few inches
of the cable, Northwire implements a dry component throughout the entire length of the
cable that only activates when wet. Highly effective in preventing and mitigating leaks,
this unique alternative also allows for a much more convenient and cleaner process
when installing and handling the cable.
