Passive millimeter-wave (PMMW) imaging is a method of forming images through the passive detection of naturally occurring millimeter-wave radiation from a scene. Although such imaging has been performed for decades (or more, if one includes microwave radiometric imaging), new sensor technology in the millimeter-wave regime has enabled the generation of PMMW imaging at video rates and has renewed interest in this area. This interest is, in part, driven by the ability to form images during the day or night; in clear weather or in lo ....etc

The Half Adder & Full Adder
The Half Adder
Adds two binary digits
Produces a sum bit(S) and a carry bit(C)
Carry C is the AND of A and B
ie,C=AB
Sum is the X-OR of A and B
ie,S=AB+AB
The Full Adder
Adds two bits and a carry input
Outputs a sum bit and a carry
Adds the bit A&B and carry frm previous column(carry in)

Abstract
This paper proposes a feed-forward control in a halfbridgeresonant dc page link inverter. The configuration of feed-forwardcontrol is based on synchronous sigma-delta modulation and the halfbridgeresonant dc page link inverter consists of two inductors, onecapacitor and two power switches. The simulation results show theproposed technique can reject non-ideal dc bus improving the totalharmonic distortion.
Keywords—Feed-forward control, Resonant dc page link inverter,Synchronous sigma-delta modulation.

Single-phase half-bridge inverter


Operational Details

Consists of 2 choppers, 3-wire DC source
Transistors switched on and off alternately
Need to isolate the gate signal for Q1 (upper device)
Each provides opposite polarity of Vs/2 across the load

DC Supply Current
If the inverter is lossless, average power absorbed by the load equals the average power supplied by the dc source.
For an inductive load, the current is approximately sinusoidal and the fundamental component of the o ....etc

Z-Wave

Z-Wave is the interoperable wireless communication standard developed by Danish company Zensys and the Z-Wave Alliance. It is designed for low-power and low-bandwidth appliances, such as home automation and sensor networks Radio specifications Bandwidth: 9,600 bit/s or 40,000 bit/s, fully interoperable Radio specifics In Europe, the 868 MHz band has a 1% duty cycle limitation, meaning that a Z-wave unit can only transmit 1% of the time.

This limitation is not present in the US 908 MHz ban ....etc
