Title: Multi-channel echo cancellation with adaptive filters having selectable coefficient vectors
Inventor: HIRANO AKIHIRO
IPC: H04M9/08
Filed: 1993-02-01
Abstract: A multi-channel echo canceller comprises a set of subtractors connected respectively in communication channels for respectively receiving a signal from a respective microphone and cancelling an echo contained in it with a cancelling signal, and a set of adaptive filters associated respectively with the subtractors. Each adaptive filter has a set of vectors of filter coefficients. A time difference between propagation delays of the received signals is estimated, and a signal having the largest content of echo components is selected and applied to the adaptive filters. One of the coefficient vectors is identified according to the estimated time difference and the selected signal. Each adaptive filter varies its filter coefficients of the identified vector with a correction term proportional to the output of the associated subtractor for filtering the selected signal using the coefficients of the identified vector to derive an echo replica, which is supplied to the associated subtractor as the cancelling signal.

Abstract: A tray assembly for use in receiving and retaining used moist brewing substances and the like from a beverage brewing apparatus and separating a liquid portion therefrom.  The tray assembly is in communication with an entry port which deposits moist brewing substances therein. A drain line in the brewing apparatus carries separated liquids away from said tray assembly.  The tray assembly includes a tray body, a liquid separation portion retained in said tray body for drawing off liquids from moist brewing substances, and a controllably sealable tray valve assembly attached to the tray body and operatively engaging the drain line for draining liquids from the tray assembly. A first area in the tray body between the entry port and the liquid separation portion communicates with the entry port and defines a receiving and retaining space.  A second area in the tray body between the liquid separating portion and the valve assembly communicates with the tray valve assembly and defines a liquid collection space.  Drained brewing substance is retained in the receiving and retaining space for removal at a later time.  Liquid drawn off of the brewing substance into the liquid collection space flows from the tray assembly out through the tray valve assembly when engaged with the drain line.

Patent CA-2095304-A1 (CA)
Inventor: JOHNSTON RONALD H
IPC: H01Q9/04
Filed: 1993-04-30
Abstract: A polarization pattern diversity antenna is described that is easy to manufacture, has a compact planar shape and radiates a nearly omnidirectional radiation pattern in the horizontal plane. Two feed points, each one attached toa copper patch, are operated in phase and 180° out of phase to separately receive or transmit two different components of a signal. The copper patches are arranged symmetrically on one side of a dielectric layer in such a way as to reduce the r.f coupling between the two modes of operation and thus increase the radiation efficiency and isolate the overall input/output ports for the different signal components.  The ground plane, situated on the underside of thedielectric layer, allows the antenna to operate like a resonant slot when the feed points are excited in phase. Using diversity, the antenna can reduce the multipath fading effects inherent in mobile communications

Abstract: FISHING ROD FOR BAIT FISH AND THE LIKE          Abstract of the Disclosure A fishing rod (10) that includes a handle (14) to which a shaft (12) and reel (16) are attached. The shaft is formed with a bore (28). An open-mouthed flute (20) is attached to the end of the shaft distal from the handle. A fishingline (18) wound onto the reel extends through the shaft and the flute. A num-ber of hooks (24) are attached to the fishing line (18) by a number of individ-ual, relatively short, gangion lines (26). A weight (22) is attached to the freeend of the fishing line (18). The flute and the shaft are dimensioned so that the fishing line and hooks can readily pass into the bore of the shaft. The flute is further dimensioned so that, as fishing line is wound onto the reel, the weight will abut the inside surface of the flute that defines the mouth. Thus, when the rod assembly (10) is not used, the hooks remain housed inside the shaft. This prevents the hooks from becoming caught on adjacent articles in the environment or becoming tangled among themselves.

Title: High performance cascadable simplex switch
Inventor: CROUSE RICHARD S
IPC: H04L12/56
Filed: 1993-12-17
Abstract: ABSTRACT            A serial simplex switch design is provided which includes I/O ports  each  of  which  is  configurable  specifically  for attachment   to   a   data   communications   subsystem   or, alternatively,  for  cascaded  connection  to  a  similarly configured I/O port on another switch. The switch provides a packet routing function including input and output buffers for each of its I/O ports wherein packets of control messages sent by  one  subsystem  are  temporarily  stored prior  to  being delivered to the  appropriate  destination  subsystem.  When configured to be directly attached to a subsystem, the I/O ports separate control messages from incoming integrated data and control message strings.  In a cascade configuration, however,  a mechanism is provided wherein data and control messages are separated into two physical paths to eliminate the delays associated with integrated data and control message flow  through  the  cascaded  I/O  port.  Each  I/O  port  is configurable to either of these methods of operation by means of programmable latches associated with the I/O port.
