This document discusses methods for measuring cell dimensions under a microscope using an ocular micrometer and stage micrometer. An ocular micrometer is placed in the eyepiece and calibrated against a stage micrometer, which has a known scale, to determine the size of objects viewed at different magnifications. The procedure involves superimposing the scales of the two micrometers to calculate the size represented by each unit on the ocular micrometer. This allows measurement of cell structures and dimensions at magnifications from 4x to 100x. Determining magnification and using calibrated micrometers is essential for obtaining accurate cell size measurements from microscope images.
Micrometry and camera lucida
Micrometry is the measurement of microscopic objects using a micrometer attached to microscopes. The micrometer was invented by William Gascoigne and improved by Robert Hooke. Microscopic measurements are performed in the range of 0.2μ to 25μ. A stage micrometer provides a standardized scale against which an ocular micrometer can be calibrated at different magnifications. The camera lucida is an optical device that projects the microscope image onto a surface, allowing accurate outline drawings to be made at the correct scale and proportions.

Physical Security Management System
My presentation at 7th Business Security Conference in Warsaw. Describes ON Semiconductor approach to implement Physical Security Management system globally.
Gps
GPS was created during the Cold War to allow fast and accurate location fixes for submarines and missile launches. It works using a constellation of 24 satellites that continuously broadcast radio signals. By measuring the time it takes for signals from at least 4 satellites to reach a GPS receiver, its precise 3D location can be calculated. Sources of error include atmospheric effects, clock errors, receiver errors, landscape features, and multipath errors. An ideal tsunami warning system incorporates detection technologies like seabed monitors and ocean buoys, as well as effective information dissemination to alert communities and enable quick evacuation.

The document provides an overview of topics covered in a course on secure and intelligent Internet of Things, with a focus on wearables and motion sensing. It includes announcements about the course, a discussion of readings, and a recap of concepts like IoT devices, power-performance tradeoffs, the Kinect pose estimation pipeline, and motion sensors. The document summarizes how accelerometers and gyroscopes work and how sensor fusion can provide a better estimate of orientation than single sensors. It also discusses Apple's patent on short-range connectivity and considerations for evaluating smart watches.
Total station
Total stations are surveying instruments that electronically measure angles and distances to calculate locations of points. They combine an electronic distance meter, theodolite, and microprocessor. Measurements can achieve angular accuracy of 1-20 seconds and linear accuracy of 2-10 mm per km. Total stations are used for topographic surveys, construction layout, and other applications. Proper use requires careful centering, accurate pointing, averaging multiple measurements, and accounting for environmental factors.
Automated Drowning Detection and Security in Swimming Pool
This document describes an automated system to detect drowning incidents in swimming pools. The system uses differential pressure sensing to monitor pressure changes when someone enters the water. A pressure sensor worn on the wrist transmits data to a receiver module at the pool site via RF. When pressure exceeds a threshold, indicating the person is submerged, the receiver sounds an alarm and activates a motor to lift an acrylic plate and bring the person to the surface of the pool for safety. The system aims to detect drowning incidents earlier than human lifeguards to save lives.
Underwater Object Recognition
This document presents a method for underwater object recognition using data from multibeam echo sounders and side scan sonar. Experiments were conducted off the coast of Alexandria, Egypt to detect objects like pipelines, rocks, and shipwrecks. The method involves acquiring sonar data, converting it to 3D and 2D images, extracting features, and recognizing objects by matching them to basic geometric shapes. The approach was tested on real data containing pipelines and validated using artificially generated objects like a pipe, shipwreck, and rock. Results showed the system could accurately recognize different underwater objects in a fast and flexible manner to aid hydrographic surveys.
Compendium.imaging.physics
This document provides an overview of imaging physics and the types of sensors used to record images. It discusses three main types of sensors: point detectors with 2D scanning, linear sensors with 1D scanning, and area array sensors with no scanning required. Semiconductor detectors like photodiodes, phototransistors, and photogates are commonly used area array sensors. Photogates in particular work by using a depletion volume and electric field to separate electron-hole pairs created when photons are absorbed, generating a signal. The document also discusses color separation techniques and factors like photon energy needed to create electron-hole pairs that impact semiconductor detector sensitivity.

The document summarizes research using data from the DEMETER microsatellite to study possible links between seismic activity and ionospheric disturbances. It presents two case studies: 1) Unusual ionospheric observations detected by DEMETER over Japan days before a 2004 earthquake. Spectrograms showed electromagnetic perturbations. 2) Observations by DEMETER of ultra-low and extremely low frequency emissions one day before a 2004 Indonesia earthquake, including anomalies in the electric field and ELF magnetic field variations. The document examines the satellite's scientific objectives, instruments, and operation modes to systematically search for seismic-related signals in the ionosphere.
Orbital Debris Mapping
The mission aims to map space debris in low Earth orbit between 1,000-3,000 km using 6 small satellites. Each satellite will use an infrared camera to image debris and calculate its orbit. The satellites will be placed in 3 evenly spaced orbital planes by a Delta II rocket and slowly lower their orbits over 30 days to map the entire region. Their design emphasizes modularity for low cost and mass, using commercial off-the-shelf components, with a focus on thermal control, power, communications and orbital maneuvering systems to complete the debris mapping mission.

Tot.st 1
Total station is a surveying instrument that combines an electronic distance meter (EDM), an electronic theodolite, and a microprocessor. It can measure horizontal and vertical angles as well as sloping distances to target objects. Total stations provide accurate linear, angular, and elevation measurements and allow for automated data collection in the field. They have largely replaced traditional surveying equipment like tapes, levels, and transits due to their increased speed, accuracy, and capabilities.
DATA LOGGER
1) The document describes an experiment conducted by students to investigate Faraday's Law of magnetic induction using a data logger. The experiment involved dropping a magnet through a coil of wire and measuring the induced electric field with a PC oscilloscope.
2) The results from the experiment showed both positive and negative voltages being generated as the magnet passed through the coil. This is because the leading and trailing poles of the magnet induce electric fields in opposite directions, according to Faraday's Law.
3) Using data loggers in science experiments provides advantages like automated and accurate data collection over long periods without human intervention. It also saves time and allows experiments to be repeated efficiently.

This document describes a system to help prevent fishermen from crossing maritime boundaries and entering dangerous areas. It uses GPS, ultrasonic sensors, a vibration sensor and microcontroller on boats. The GPS tracks the boat's position and the microcontroller compares it to boundary coordinates. If the boat approaches or crosses the boundary, an alarm alerts the fishermen. It also sends a message to coastal guards. Ultrasonic sensors detect icebergs and the vibration sensor predicts tsunamis. If the boat keeps moving past the boundary, the motor can be remotely stopped. The system aims to save lives by keeping fishermen from entering restricted or dangerous waters.
