    Currently this process to determine when to switch between sites is only done when the radio is on the control channel. When a subscriber receives a voice channel grant, the subscriber will transition to the voice channel and suspend the sampling proc- ess. The subscriber will remain on the voice chan- nel until a...

    High dynamic range of the HF SSB receiver is one ofits important design goals. High dynamic range can be achieved by using RF elements that have high IP3, high 1 dB compression point and low noise figure. RF amplifiers are such elements, and increas- ing their IP3 or their 1 dB compression point gener- ally increases...

    Telecommunications systems consist of two dis- tinct areas of responsibility: the user side and the network side. Users interface their equipment to the network with some type of communications termi- nating equipment. Examples of these include multiplexers, channel banks, Tl CSUs and DSWCSUs. (Analog modems too, but...

    In today's SmartZone systems, the subscriber units use RSSI (Received Signal Strength Indica- tion) sampling algorithms in order to determine what the received signal strength ofadjacent RF sites are. This allows the subscriber units to rank adjacent sites ahead of time and allow it to switch to the next best adjacent...

    Portable radio users ofien utilize signaling to con- tact specific units. This device provides the ability to perform this signaling in either a noise free envi- ronment or a loud area that would mask normal methods of signaling. The units location in the remote microphone allows the user to purchase an accessory that...

    Ocean /air Surfing April 27 2002 1. The Concept The purpose of this creation is to enable persons with existing paragliding skills to pilot their gliders in the sky in much the same manner as a surfer controls the speed and direction of his surfboard across the ocean. This is accomplished by attaching hardware to...

    Wet chemical etching ofunmasked silicon regions is performed in semiconductor discrete processing to form deep moat and mesa device terminations. The contour of resulting moat/mesa silicon sidewall is very steep and leads to inadequate (thin or miss- ing) photoglass at the top of the silicon step (see Figure 1). In...
