Patent CA-2084499-A1 (CA)
Title: Emi shield apparatus and methods
Inventor: WEBER WILLIAM F
IPC: H05K7/14
Filed: 1992-12-03
Abstract: A top cover and bottom cover made of an electrically conductive material that absorbs and reflects electromagnetic interference (EMI) signals are formed to fit without solder or welding as an EMI shield apparatus over EMI susceptible electronic circuitry on a printed circuit board.  The EMI shield apparatus shields the circuitry from EMI while at the same time permitting the communication of desired electromagnetic radio frequency and electrical signals to the circuitry.  The EMI shield apparatus includes the use of an electrically conductive layer that is integral to the top and bottom sides of the printed circuit board and which includes conductive channels that penetrate the printed circuit board.  The channels prevent EMI from passing through the printed circuit board to the electronic circuitry.  Also, the channels receive tangs found both on the top cover and bottom cover.  The tangs are positioned to prevent EMI from passing through the top and bottom cover junctures with the conductive layer.  As EMI signals reach the shield apparatus, they are absorbed and conducted through the shield EMI apparatus to an electrical ground or reflected from the EMI shield.  Openings on the top cover permit desired electromagnetic radio frequency signals to reach the electronic circuitry.  Passageways through the conductive layer permit electrical leads from the electronic circuitry to connect to external circuitry.

Patent CA-2092240-A1 (CA)
Title: Fractionally spaced maximum likelihood sequence estimation receiver
Inventor: WAN YONGBING
IPC: H04L25/03
Filed: 1993-03-23
Abstract: The channel-impulse-response estimator (44') in a maximum-likelihood-sequence-estimation receiver produces channel-model parameters for a model that produces outputs not only for symbol times but also for intermediate times between the symbol times. A symbol-sequence-derivation circuit (42') determines the most-likely sequence on the basis of metrics computed from the differences between the received signal and the responses of the model to candidate sequences not only at the symbol times but also at the intermediate times. An interpolator (100) receives the symbol decisions from the symbol-sequence-derivation circuit (42') and generates intermediate values from them by simulating the Nyquist filter formed by the concatenation of pulse-shaping filters (22 and 24) in the transmitter and matched filters (36 and 37) in the receiver.      The channel-impulse-response estimator (44') uses these values together with the derived-symbol values as inputs to its updating process to maintain the model.

Title: Time delay control for serial digital video interface audio receiver buffer
Inventor: KLINGLER KEITH L
IPC: H04N7/52
Filed: 1993-06-29
Abstract: PATENT     ABSTRACT           An audio receiver FIFO memory buffer in the serial digital video interface allows improved timing synchronization between video and audio information. Furthermore, it eliminates unpleasant sound effects when multiple data samples are skipped or repeated in series. This FIFO receiver buffer receives data at an input write-data rate filling up the memory storage cells therein. An output read-data signal clocks the data out of the memory storage cells. The FIFO's fullness is monitored and maintained, in response to an external signal, to within a specified range delimited by an upper and a lower threshold. If the FIFO buffer fullness is below the range's lower threshold, then the FIFO's read address pointer is held so that the immediately preceding read out data element is read out again, but only once. On the other hand, the FIFO buffer fullness is over the range's upper limit, then the FIFO's write address pointer is held so that the immediately preceding written in data element is written over, but only once.
