Desire cad drawings that will diagram the interconnections of various makes and models of video surveillance equipment with appropriate call-outs, to refelect POE connections for catagory 5 data connections, low voltage power, and AC power supply connections and physical placement of equipment.
Additionally would like to superimpose equipment placement over exisiting PDF scans of each of the building's electrical floor plans.
Desire to follow U.S. standards as to electrical symbology, etc. wherever possible.
- Whatever will work best for designer.
<p>To: Potential Designers,</p>
<p>The attached drawing has both a single line schematic, and a floor plan of one of 5 controller rooms.</p>
<p>The surveillance equipment is IP based and battery backed up.</p>
<p>We want to have a single line schematic that reflects the interconection of two basic equipment packages. The first is for installation in each of the controller rooms and the second is an outdoor package centered around a pan, tilt, zoom camera which is utility pole mounted and also has battery UPS for power.</p>
<p>Once we have the single line schematics of how the equipment interconnects for the electricians we would then make drawings that place the equipment into the controller rooms in essence superimposed over the other engineering drawings that we have reflecting the layout of the other controller rooms.</p>
<p>There are Qty (5) rooms total and there are Qty (4) PTZ camera postions.</p>
<p>more information available upon request.</p>

Antenna Design and Development in Ansys HFSS
Good day!
I have a project that might be of interest to you, and I would like to share the technical specification below.
If this task matches your expertise and interest, I would be glad to discuss further collaboration.
I look forward to hearing from you.
Technical Specification for the Antenna Design and Development in Ansys HFSS
1. General Requirements
Frequency Range: 500 MHz – 2700 MHz
Antenna Type: Directional
Beamwidth (Main Lobe Width -3): Not less than 30°
VSWR: Not greater than 1.4 across the entire operating frequency range
Gain: At least 15 dBi throughout the frequency range
Operating Power: 100 W
2. Additional Technical Conditions
Frequency Band Division:
The operating frequency range may be divided into 2 or 3 sub-bands to improve efficiency and achieve gain values exceeding 20 dBi within each sub-band. (in this case, a separate antenna for each sub-bands)
Construction:
The antenna shall have a rigid mechanical design, suitable for mast or structural mounting.
Connection:
The antenna shall use LMR-400 or equivalent coaxial cable with an N-type connector.
3. Recommendations on Materials and Manufacturing
Metal Version:
The antenna may be manufactured from sheet metal (galvanized steel, copper, or aluminum).
There is access to laser cutting, bending machines, and laser welding, which allows the fabrication of precise and rigid metal constructions.
Alternative Version:
The antenna may alternatively be 3D printed using a photopolymer printer, followed by copper electroplating.
This method allows the realization of antennas with complex spatial or fractal geometries.
4. Multiple Antennas and Switching
In the case of dividing the operating range into multiple antennas
(for example: 500–900 MHz, 900–1700 MHz, 1700–2700 MHz),
a digital RF switch must be implemented to programmatically route the signal to the corresponding antenna.
Switch Control: Digital
Switch Power Handling: Up to 100 W, without significant signal degradationInsertion Loss: Must be accounted for in the overall system efficiency
Magnetic Induction Wireless Charger
Multi-unit wireless charger (up to 50 devices) in one case (similar to a suitcase). Must consider heat (exhaust, etc) within a multi-level charger inside of a large portable case (i.e. pelican case). Winner must include production level design with materials and function.
CAD Concept for Bracelet Prototype Design
emBrace.me is a GPS bracelet that should be designed for kids (ages 3-10).
The main use-case for the bracelet will be during a family visit to amusement parks / Shopping Malls etc.
Key features
1) Electronic's dimensions: 30X35X10mm
2) Child proof lock mechanism
3) Standard Micro USB input (hidden on the side)
4) Screen/watch is optional
5) Only 1 "Answer/Call" button
6) Slick design !!! (no cheap plastics please)
7) QR code embedded on the bracelet (on the outer layer)
8) GSM slot (similar concept to the iPhone Sim card + eject option)
