    摘要： A microwave radio assembly is described including a directional antenna wherein the installation and aiming is simplified. The assembly is attached to the wall-mount fix via gimbals mechanism with one rotation axis for azimuth and one for elevation and the assembly preferably includes a sight mechanism including a pair of visual apertures is located in the radio assembly in a line parallel to the radio antenna radiation direction. The radio assembly further includes a modulation cancellation scheme in full duplex mode.

    摘要： A microwave radio terminal capable of multiple gigabits/sec bit rate is provided. The radio terminal may use QAM modulation, including the two lowest modulation formats of BPSK and QPSK. The serial bit stream, including forward error correction (FEC) and all other overhead, is prepared in a digital circuit, such as a filed programmable gate array (FPGA) and is output serially, using SERDES devices inside the FPGA, as two separate channels known as “I-channel” and “Q-channel”.

    摘要： A hand-held or portable diathermy apparatus is disclosed comprising a housing, a battery power supply preferably within the housing, and at least one electrode carried by the housing. The apparatus includes a radio frequency power generator for generating an oscillatory current ranging between about 1 kilohertz and about 20 megahertz, and supplying this oscillatory current to the electrodes. A manually operated switch is carried by the housing for selective energization of the radio frequency generator whereby, upon energization thereof, the apparatus is capable of being cycled several times outputting up to about 20 watts of power for up to 20 seconds or more on each cycle.
