Patent CA-2040659-A1 (CA)
Title: Digital signal processing device
Inventor: CHEN KEPING
IPC: G06T1/00
Filed: 1991-04-17
Abstract: A  device  for  digital  signal  processing  and particularly  suited  for  video  and  image  processing applications. The device includes a linear array of 1024 processing  elements  (PE's),  an  external  controller interface,  input/output ports,  and an external memory interface.  The input/output ports allow the device to interface to equipment such as digitizing cameras and video  display  monitors.  The  device  uses  a  single instruction multiple data topology (SIMD) and incorporates two modes of communication: horizontal and vertical. Shift registers provide horizontal, i.e. parallel, communication between the PE's in the linear array. The linear array of processing elements  provides  one PE  for each digital sample, e.g. a pixel, thereby allowing a sequence of data samples, e.g. a video line, to be processed in real-time. Each PE includes a bit-serial arithmetic logic unit, a cache  memory  and  an  external  memory  interface.  All communication within a PE is along a one-bit wide bus, i.e. vertical mode, using a single move instruction with variable source and destination addresses. The processing capability of the device is further enhanced by having a serial-parallel multiplier in each PE. For applications requiring more than 1024 PE's, two or more devices can be cascaded together. In another embodiment of the present invention,   dual-port   memories   provide   horizontal communication between the PE's in the linear array.

Title: Digital data radio transmission system
IPC: H04L25/05
Filed: 1991-09-04
Abstract: A digital data radio transmission system for reproducing  pre-velocity-modulation input frame data  from the radio frame data subjected to velocity modulation and pulse insertion.  The system includes a write counter that divides write clock pulses under control of frame position pulses to output write pulses; an elastic memory that temporarily  stores  the  input frame data  and  the  frame position pulses as per the write pulses; and a timing pulse generator that outputs control pulses in response to the supply of read clock pulses under control of the frame position pulses from the elastic memory.  The system fur-ther comprises a read counter that divides the write  clock pulses by the same number as with the division by the write counter to output read pulses; and a pulse inserting sec-tion that inserts pulses into the output frame data read from the elastic memory as per the read pulses to generate the  radio  frame  data.  8ecause  the  control  operations involved are performed in accordance with the frame posi-tion pulses, the input frame data matches the radio frame data in terms of frame phase.

Title: Load-indicating fasteners
Inventor: WALTON BRIAN
IPC: G01L5/00
Filed: 1990-11-13
Abstract: A load indicating fastener such as a bolt (10) or stud, has a shank (12) which is subject to tensile loading in use. The shank (12) has an axially extending bore (22) which receives a first gauge pin (30) anchored at its inner end (32) to the shank (12) and protruding outwards beyond an end face (16) of the fastener. An indicating member (40) is rotatable on the protruding portion of the gauge pin (30) between the end face (16) of the fastener and the head (34) of the pin (30), so that the indicating member (40) is free to rotate when the shank (12) of the fastener is unstressed but when the shank (12) is subject to a predetermined tensile loading is held against rotation by contact with the end face (16) of the fastener. A second gauge pin (42) is received within an axially extending bore (36) in the first gauge pin (30) and is anchored at is inner end and protrudes outwards beyond the outer end of the first gauge pin (30). A second indicating member (50) is rotatable on the protruding part of the second gauge pin (42), between the head (46) of the pin (42) and the first indicating member (40). The second indicating member (50) is free to rotate when the shank (12) of the fastener is unstressed or subject to the first predetermined loading, but when the shank (12) is subject to a second predetermined tensile loading greater than the first predetermined loading, the second indicating member (50) is held against rotation by contact with the first indicating member (40).  The first indicating member (40) provides an indication when the fastener has been tightened to a desired loading. The second indicating member (50) provides an indication when the fastener has been overloaded.

Title: Recorded message delivery system
Inventor: POCH NEIL
IPC: H04B5/00
Filed: 1990-10-03
Abstract: The invention concerns a recorded message delivery system for use in museums or tourist attractions. The system supports multiple messages for example, one message per exhibit and a user operated message player may be programmed to receive messages in one of a plurality of languages. The messages may be transmitted, for example, on different frequencies of the FM band to be received and played by the receiver/message player. Messages are played without regard for sequence at the demand of the user who may choose any message by keyboard operation of a panel of the receiver. Thus, for example, by pressing key #5 the user may hear the message relating to exhibit #5 in the language for which the receiver/player is programmed. Frequencies may be reused in different locations of the museum or attraction.

Title: Surgical fluid evacuation system
Inventor: MCCARVER STACEY G
IPC: A61B19/08
Filed: 1992-06-05
Abstract: Disclosed herein is a fluid evacuation system which is particularly well-suited for removing liquids from the site of a surgical procedure. In one configuration the system is in the form of a pad which can be placed directly on a patient or used in conjunction with a surgical drape. The pad is connected to a vacuum source and as fluids flow across the top surface of the pad, they are drawn down into a fluid receiving chamber and then removed via a suction line. As a result, fluids present during a surgical procedure are taken completely away from the operating site. In another configuration, the system is in the form of a suction rail which operates in the same fashion but can be molded or formed into a particular shape and then attached to a surgical drape in the expected path of fluid run-off.

Title: Check valve
Inventor: NELSON WILLIAM A
IPC: F16K15/02
Filed: 1992-06-26
Abstract: IMPROVED CHECK VALVE                  ABSTRACT OF THE DISCLOSURE   A  check  valve  is  provided  that  is  especially  useful in gas-assisted injection molding wherein pressurized gas is injected into molten plastic material.  A tapered or cone-shaped valve member which seats  into  a  correspondingly  tapered  or  cone-shaped  valve  chamber provides the means by which the valve seals against reverse flow.  Any plastic material entering the gas passageway would contact the base end of  the  tapered  or  cone-shaped  valve  member  and  not  any  sealing surfaces.  By minimizing contact with the sealing surfaces,  the useful lifetime of the check valve is significantly increased.

Abstract: Abstract Of The Disclosure A swivel  head with manifold  assembly having remote control valves and plug release plungers.   The assembly comprises a body connectable to a tool string, and a cementing manifold connectable to the cement source.   The cementing manifold has  remotely controllable cement control valves incorporated therein.  The manifold is rotatably mounted on the body to provide continuous fluid communication between the manifold and body even when the body is rotating with respect to the manifold.   The rotatable mounting is provided by a swivel connection comprising a mandrel extending from the body and a sleeve connected to the manifold.  The swivel connection also provides continuous communication between a pressure line, extending from the sleeve to a pressure supply, and another pressure line, extending from the mandrel to a dart or ball releasing mechanism.  This allows the releasing mechanism to be actuated even when the body is rotating with respect to the  manifold  and  when  the  entire  apparatus  is  being reciprocated.  Preferably, another swivel connection is used which also provides continuous fluid communication between the manifold and body.  A plug release indicator is also provided in one preferred embodiment.
