IPC: H04N11/04
Filed: 1990-08-28
Abstract: CONDITIONAL MOTION COMPENSATED INTERPOLATION             OF DIGITAL MOTION VIDEO Abstract Motion digital video is encoded and decoded by a motion compensated interpolation method and apparatus. In accordance with the method, selected frames of the video are interpolated in the decoder with the aid of interpolation correction codes that are generated in the encoder and sent to the decoder. In an encoder embodiment that interpolates half of the frames, every other frame is encoded and decoded within the encoder. The decoded versions of adjacent frames are appropriately combined and compared to the interleaved camera frame that is to be interpolated in the decoder. The differences, which correspond to "pels correction" information, are encoded and quantized. Those that exceed a predetermined threshold value are added to the encoder's output buffer. The inverse operation is carried out in the decoder. That is every pair of decoded frames is averaged andcombined with the decoded "pels correction" information to form the interpolatedframes.

Abstract: COAXIAL-TO-MICROSTRIP ORTHOGONAL LAUNCHES         ABSTRACT OF THE DISCLOSURE     An orthogonal coaxial-line-to-microstripline transi-tion is described.  The transition employs capacitively loaded troughline transmission line to interface between the  coaxial  line  and  the microstripline.   Because the field configuration of the troughline shows similarities to both the coaxial line and the microstripline config-urations, a well matched transition between coaxial line onto microstripline.  The center conductor of the trough-line  can  be  bent  at  right  angles  with  no  mismatch. Dielectrically  loading  the  troughline  prevents  higher order modes from radiating out of the trough.

Inventor: JOHNSON ROBERT M JR
IPC: H04B1/10
Filed: 1992-06-09
Abstract: A radio frequency receiver (300) typically contains electronic devices commonly used in amplifying or mixing circuits (315) which are seldom ideal. The non-ideal characteristics of these devices lead to intermodulation (IM) distortion. A measurement of the amplitude of the received signal (301) is taken both unattenuated (503) and attenuated (507). The difference between the two measurements is compared (511) to predetermined limits (L1, L2 or L3) wherein the received signal (310) is determined to be valid, invalid or unsure. valid received signal is demodulated in the receiver (300). An invalid signal, confirming the presence of IM distortion, is rejected. The unsure signal may be rejected or demodulated as determined by the receiver designer. This type of signal characterization is particularly useful for cellular radiotelephones (101) attempting to gain access to the system provider (111) in which it is registered.

Inventor: HOLBROOK RUSSELL W
IPC: B43M5/04
Filed: 1992-08-07
Abstract: A mail handling machine includes a mechanism for serially transporting along a main path sealed and unsealed close-flapped envelopes, some of which may be mis-sealed.      The machine also includes a mechanism for opening the flaps of the unsealed close-flapped envelopes. The flap opening mechanism includes a shaped blade pivotally mounted on the machine and located along the main path. There is also a shaped portion of a deck that includes a fixed guide edge located along the path and downstream of the blade. The blade strips open the flaps of the unsealed envelopes. A member is hingedly mounted to the trailing edge of the blade. The member is biased so as to obstruct the gap between the blade and the guide edge to prevent opened flaps from entering the gap.      When a mis-sealed envelope engages the blade, causing the blade to move pivotally, the shaped portion cams up the member, which contacts the mis-sealed envelope and urges it out of engagement with the blade.
