Nutrition Basics
Chapter 9
*
Essential nutrients: those we must get
from food
Proteins, fats, carbohydrates, vitamins, minerals and water
Macronutrients
Micronutrients
These nutrients are available to the body through digestion
An adequate diet must provide nutrients and energy
Nutritional Requirements: Components of a Healthy Diet
*
Kilocalories (kcal) are the measure of energy in food
2000 kcal per day typically meets a person’s energy needs
Energy is the capacity to do work; calories measure energy
Sources of energy:
Fat = 9 calories per gram
Protein = 4 calories per gram

Carbohydrates = 4 calories per gram
Energy
*
The Six Major Classes of Dietary Components
*
The Digestive System
Proteins form parts of muscle, bone, blood, enzymes, hormones,
and cell membranes
Amino acids: the building blocks of proteins
There are 20 common amino acids
9 are essential
11 are nonessential—meaning the body can produce them
Proteins—
The Basis of Body Structure
*
Complete proteins provide all essential

amino acids
Most animal proteins are complete proteins
Most plant proteins are incomplete proteins
Legumes, nuts
Certain combinations yield complete proteinsRecommended
protein intake:
0.8 gram per kilogram of body weight
AMDR: 10–35% of total daily calorie intake
Proteins—
The Basis of Body Structure
*
Protein Content of Common Food Items
Fats (lipids) are the most concentrated source of energy
Store energy; provide insulation and support
Major fuel during rest and light activity
Linoleic acid and alpha-linolenic acid are
essentialTriglycerides: most fats in foods
Types: saturated or unsaturated; monounsaturated;
polyunsaturated
Fats—
Essential in Small Amounts
*

Hydrogenation and trans fats
Hydrogenation changes some unsaturated fatty acids in trans
fatty acids
Associated with increased LDL-C (“bad” cholesterol) and
decreased HDL-C (“good” cholesterol)Recommended fat intake
Limit unhealthy fats
AMDR for fats is 25–35% of total daily calories
Fats—
Essential in Small Amounts
Types of Fatty Acids
Carbohydrates supply energy for body cells
Simple carbohydrates
Monosaccharides: single sugar molecule
Glucose, fructose, galactose
Disaccharides: pairs of single sugars
Sucrose, maltose or malt sugar, and lactose
Complex carbohydrates: multiple sugar units
Starches and fiber
During digestion, carbohydrates are broken down into glucose
for absorption
Glycogen: starch stored in liver and muscles
Carbohydrates—
An Ideal Source of Energy
*

Refined carbohydrates versus whole grains
All grains are whole before processing
Inner layer: germ
Middle layer: endosperm
Outer layer: bran
During processing, the germ and bran are removed, leaving just
the starch of the endosperm
These refined carbohydrates are lower in fiber, vitamins,
minerals, and other beneficial compounds
Carbohydrates—
*
The Parts of a Whole Grain Kernel
Glycemic index:
Insulin and glucose levels rise and fall
A quick rise in glucose and insulin levels produces a high
glycemic index
Eating high glycemic index foods
May increase appetite
May increase risk of diabetes and heart disease
Unrefined grains, fruits, vegetables, and legumes: relatively low
glycemic index
Carbohydrates—

Recommended carbohydrate intake:
The average American consumes
200–300 grams daily
130 grams are needed to meet the body’s requirements for
essential carbohydrates
AMDR: 45–65% of total daily calories, or
225–325 grams
The USDA recommends that total calories from added sugars
and saturated fats combined be no more than 15% of total daily
caloric intake
Carbohydrates—
Types of fiber:
Dietary fiber: nondigestible carbohydrate that is present
naturally
Soluble (viscous) fiber
Insoluble fiber
Functional fiber: nondigestible carbohydrate that has been
isolated or synthesized
Total fiber is the sum of both
Fiber—A Closer Look
*
Sources of fiber:
All plant substances Recommended fiber intake:

38 grams for adult men
25 grams for adult women
Needs to come from foods, not supplements
Fiber—A Closer Look
*
Vitamins are organic (carbon-containing) substances required in
small amounts to regulate various processes in cells
Thirteen vitamins:
4 fat-soluble: A, D, E, and K
9 water-soluble: C, and the B-complex vitamins thiamin,
riboflavin, niacin, vitamin B-6, folate, vitamin B-12, biotin, and
pantothenic acid
Vitamins—
Organic Micronutrients
*
Functions of vitamins:
Help chemical reactions take place; help unleash energy;
produce red blood cells; maintain nervous, skeletal, and immune
systems; and act as antioxidantsSources of vitamins:
The human body does not manufacture most vitamins
Abundant in fruits, vegetables, and grains
Vitamins—

*
Vitamin deficiencies
Certain vitamin deficiencies are associated with health
risksVitamin excesses
Extra vitamins can be harmful, even toxicKeeping the nutrient
value in food
Store and cook food properly
Vitamins—
Facts about
Vitamins
Help to regulate body functions and release energy, aid in
growth, and maintain body tissues
About 17 essential minerals
Major minerals: 100 milligrams or more/day
Calcium, phosphorus, magnesium, sodium, potassium, and
chloride
Trace minerals: minute amounts
Copper, fluoride, iodide, iron, selenium, zinc
Issues may arise if too many or too few
Anemia; osteoporosis
Minerals—
Inorganic Micronutrients

Facts about Selected Minerals
The human body is 50–60% waterHumans can live up to 50 days
without food but only a few days without water
It is used in digestion and the absorption of food and is the
medium in which chemical reactions take place
To maintain hydration, daily:
Men: 3.7 total liters of water, with 3.0 liters
(13 cups) coming from beverages
Women: 2.7 total liters of water, with 2.2
(9 cups) coming from beverages
Water—Vital but Often Ignored
Antioxidants
Reduction in cancers
(free radicals)
Vitamins C and E,
selenium, carotenoids Phytochemicals
Soy foods may help lower cholesterol levels
Cruciferous vegetables render some carcinogenic compounds
harmless
Allyl sulfides (garlic and onions) boost cancer-fighting immune
cells

This is a division of application Ser. No. 09/061,281,
filed Apr. 17, 1998, now U.S. Pat. No. 5,889,551 which is a
division of Ser. No. 08/750,921, filed Jan. 22, 1997 now U.S.
Pat. No. 5,745,166.
FIELD OF THE INVENTION
The present invention relates to a Video Security System
particularly, although not exclusively, envisaged for use in
the monitoring of a plurality of locations, Such as, in a
building, for example, a casino.
More particularly the present invention relates to a Video

Security System (VSS) particularly directed at addressing the
difficulties which prior art Security Systems generally
experience, Such as:
1. avoiding text information obliterating important Video
information;
2. Switching repeatedly between two or more views of
interest with a single camera;
3. dealing with equalisation problems between Video
cameras, video monitors and/or VCRs or other video
Signal recording device;
4. Overcoming the problem of tracking an object with a
camera when it approaches a 360 end stop;
5. Overcoming the problem of pan/tilt camera control
when Zoomed out;
6. controlling the camera to move rapidly between two or
more views of interest, and,
7. VCR management issues including: failure of VCRs;
change-Over delay in VCR cassettes, and dealing with
camera failure and replacement.
It is to be kept in mind that the purpose of the video
Security System of the present invention is to provide video
images regarding events pertaining to the Security of a
building or the like and to allow those recorded Video images
to be presentable in a court of law as irrefutable evidence of
the events which took place.
Hereinafter the term “VCR' will be used to denote any
form of Video signal recording and/or playback device

(referred to as a “VRD") and may include a video cassette
recorder, or any optical or digital recording media Suitable
for recording video signals.
BACKGROUND OF THE INVENTION
1. “Text Overlay'-In the field of video security systems
it is known to introduce text into the Video signal to provide
a real time record of the details of the event which is being
monitored. A disadvantage of Such prior art Systems is that
the information is introduced into the video part of the video
Signal and hence over-writes a part of the Video picture
which would have otherwise been recorded.
The present invention overcomes this by inserting the text
into the non-Video part of the video Signal
2. “Toggle'-The Secret to the Success of Switching
between a plurality of fixed locations is to be able to quickly
and easily identify two, or more, Viewing locations “on the
fly'. This is particularly for viewing targets of short term or
temporary interest.
In the context of the present invention “on the fly” means
to be performed whilst the VSS is in its normal mode of
operation and without interrupting the normal operation of
the VSS.
Also, in the context of the present invention the feature of
“switching back and forth between two (or more) viewing
locations is referred to as “toggling between the viewing
locations.

However, where the operator is interested in two or more
Specific locations within the viewing region the PTZ camera
must be adjusted manually between these locations. This is
quite laborious and tedious for the perSon operating the PTZ
camera Since it involves adjusting the pan, tilt, Zoom and
focus setting for the PTZ camera.
We have discovered that this can be overcome by record
ing the PTZ camera Settings corresponding to the desired
locations of Viewing into a camera position controller and
Switching between the locations by recalling the Settings for
each of the viewing locations. The PTZ camera then is
controlled by the camera position controller to adjust itself
between the desired locations.
“Preset' PTZ camera viewing locations are known and
are widely used, however, they require the operator to make
Several control operations to Set each Viewing location and
at least two control operations to Switch from one viewing

location to another.
This is particularly inconvenient in a viewing region Such
as in a casino where there are many potential targets, where
there is a requirement to quickly and reliably Set viewing
locations and where it is critical to be able to Switch between
typically two targets. The two targets would typically be a
Suspected felon and a handbag which it is Suspected that the
felon will Steal. Typically, there is an accomplice to be
monitored as well. Usually the accomplice in this Scenario
is a woman who collides briefly with the felon and takes the
handbag once the handbag has been Stolen. Hence, the task
of the operator of the VSS is to first monitor the suspected
felon and the handbag by toggling back and forth between
the two and once the handbag has been Stolen to monitor the
felon and then to monitor a person who may collide with the
felon.
In the present invention we have determined a way to
enable the operator to operate a single control function (Such
as by a control button) to set, update and toggle between two
or more viewing locations. This most reliably and efficiently
allows the operator to monitor the targets.
3. "Signal Equalisation'-Prior art video security systems
have the problem that equalisation of the Video signals must
be provided for each video camera That is, there must be one
equalisation unit for each camera
We have overcome this difficulty by having one equali
sation unit for each Video monitor and automatically adjust
ing the equalisation unit for each Video camera as it is
connected to the monitor. Hence, only a fraction of the
number of equalisation units is required.
4. “Rotation End Stops' Another problem of existing

Video Security Systems is that most of the cameras which
they use are only able to rotate through about 360. Hence,
when following a target the camera can reach its end stops
and have to unwind before it can continue to follow the
target. By the time that the camera has unwound the target
may no longer be in Sight.
We have overcome this problem in an inexpensive way by
using a cable loop wound in a way that it is able to twist 3
to 4 times, and hence the camera can be rotated through an
angle of about 1000. A control unit of the camera then is
programmed to return the camera to about the centre of its
rotation when the camera is not being used to track a target.
Hence, the camera is relatively unlikely to reach its end
Stops during normal uses.
5. “Pan Speed vs Zoom’-Prior art vide cameras have the
further problem that when the lens is Zoomed in (that is
viewing an object at a distance) the rate of pan per degree of
arc is the same as when the lens is Zoomed out. Hence, it
6,166,763

becomes difficult to accurately control the pan of the lens
when Zoomed in. Also, it is difficult to observe the image of
the camera during panning when Zoomed in because it is
usually blurred or indistinct due to the pan Speed being too
high.
We have overcome this problem by linking the pan speed
to the Zoom position of the lens So that the rate of pan per
degree of arc decreaseS as the lens is Zoomed in and
increased as the lens is Zoomed out.

6. "Accuracy of Camera Positioning-Conventional
camera position controllers have problems in maintaining
accuracy of positioning of the video camera (for viewing a
target in a predetermined location) whilst seeking maximum
Speed of movement of the Video camera. That is, in the race
for maximum speed, So that one camera can be used to
monitor two or more locations, the position controller is not
able to keep accurate record of the location of the camera.
This is primarily due to problems encountered in rapid
changes in acceleration.
We have overcome this problem by designing a camera
position controller which ensures that there is a minimum
period of Substantially Zero acceleration before any change
in acceleration direction. This thus avoids large changes in
momentum introduced when Switching abruptly from accel
eration to deceleration.
7. “Non-Recording Time' Another problem of prior art
Video Security Systems is that during the times referred to in
item 7 of the Field of the invention no recording can occur.
Hence, the Video Security System can not record all extents
which its cameras See. For example, in a video Security
system having 125 VCRs there would be a minimum record
ing time loSS of 2 hours per day due only to the time taken
to change over tapes (assuming the operation takes 30
Seconds and each tape records for 8 hours). There is further
loss of recording when an operator deliberately takes a VCR
off-line in order to review one of the tapes. In order to
overcome these periods of lost recording we have designed
a VSS to automatically manage the VCRS and cameras So as
to ensure that each target is monitored continuously and each
Video signal is recorded continuously. This is achieved by
using backup Video cameras and backup VCRS and by
providing a log of the camera and VCR associated with each

Viewed target.
