摘要： An antenna for a land-based, mobile radio communication system, having a reduced size and shape, includes three, flat antenna dielectric panels (32a, 32b, 32c), each covering one hundred twenty degrees of azimuth. On each dielectric panel are formed two, interleaved microstrip antenna arrays having narrow vertical beam width. One of the antenna arrays (36) receives signals and the other antenna array (34) transmits signals. The receive array is circularly polarized. The panels are mounted in a triangular configuration about a central mast and a cylindrically shaped radome encloses the dielectric panels.

摘要： The optical tape recorder of the present invention is capable of archiving data at rates in excess of 400 megabits per second by concurrently writing or reading a plurality of data tracks in each data trace. A read-write module (102) outputs an illumination beam (104) comprised of combined multiple write beams (channels), a read beam and an autofocus beam. Optics within the read-write module spatially combine and accurately position the plurality of beams with respect to each other to form the multi-beam illumination beam (104). A read-write head (106) comprised of a synchronized scanning transmissive polygon (110) and rotating lens wheel (112) scans the multi-beam illumination beam (104) across a recording media (108) to read or write multi-channel data tracks. An autofocus system is also included to ensure that the multi-beam illumination beam (104) is accurately focused on the recording media (108).

摘要： Separations between the end of one data file (150) and the beginning of the next data file (151) are recognized, without utilizing an entire data storage block by means of a controlling program for a peripheral recording device monitoring the control information headers (156) of helically stored data on a magnetic tape. When files are stored on the magnetic tape, the controlling program increments an increase of a file section number (152) by one and increments to zero a data block number (154) at the beginning of a new data file. When the recording device is reading the magnetic tape and there is detected an incrementation of the file section number (152) and a zero value for a data block number (154), a recognition is made that this data indicates the end of one data file and the beginning of another data file.

摘要： Monolithic microwave integrated circuit (MMIC) technology is advantageously used to fabricate microwave circuitry for an antenna-converter system to enable an antenna (102) and its associated converter circuits (109) to be integrated together into a unitary package (100). Small reliable radio frequency (RF) circuits, polarization switch matrix circuits, intermediate frequency (IF) circuits and power and control circuits for the converter are manufactured and integrated onto a plurality of small area microwave circuit disks (120-121) using MIC/MMIC technology. The plurality of converter circuit disks are sandwiched together and directly mounted flat against the back of the antenna to form a unitary package. The disks for the converter circuits are further sized such that the circuit disks fit within an envelope volume defined by the size and shape of the antenna.

摘要： The detection and correction of errors in digital data transmitted by or stored in a media channel is provided by processing the data through a triple orthogonally interleaved error correction system. On the transmit/store side of the system, the data is encoded three times prior to placement in the media channel with two different interleaving steps performed between the encoding steps. The first interleave is an orthogonal row shuffling interleave that provides enhanced protection against burst errors. On the receive/play back side, the data is decoded and deinterleaved, with included errors detected and corrected to enable recovery of the original data. To enhance the error correction, a circuit is used for generating a symbol accurate error flag identifying symbols containing errors thereby allowing the error correcting decoders to focus on and correct the data.
