Title: Passive infrared analysis gas sensors and applicable multichannel detector assemblies
Inventor: WONG JACOB Y
IPC: G01N21/35
Filed: 1996-12-26
Abstract: A passive source infrared gas detector (33) uses a passive infrared source and the space between the detector assembly (3, 79) and the source as the sample chamber. The gas detector (33) includes an infrared detector assembly (3, 79) for producing first, second, and third outputs, the first output being indicative of the radiation received at a first non-neutral spectral band which is absorbable by a preselected gas to be detected, the second output being indicative of the radiation received at a first neutral spectral band from the passive infrared source, and the third output being indicative of the radiation received at a second neutral spectral band from the passive infrared source. Signal processing means manipulate the three outputs to determine the concentration of the gas being monitored. Additional detectors can be added to the detector assembly to detect radiation at spectral bands characteristic of additional gases.

Title: Shape memory cords for reinforcing pneumatic tyres, rubberized fabrics and pneumatic tyres comprising the said cords
Inventor: ORJELA GURDEV
IPC: B60C9/00
Filed: 1998-10-14
Abstract: Process  for  the  manufacture  of  a  reinforcing fabric for articles made from rubber, such as pneumatic tyres,  conveyor  belts   flexible  tubes,  and  similar, comprising  a  plurality  of  metal  cords  orientated parallel to each other in a single direction and in which each cord comprises metal wires wound spirally around each other, wherein at least one of the wires of the cord consists of a shape memory material.     During the phase of  incorporation of  the  cords into the elastomeric material,  the shape memory wire tends to recover the shape memorized initially and, by means  of  the  force  generated  during  this  recovery, transmits by friction to the surrounding wires forces tending to shorten the pitch of the cord with spacing of  each  wire  from  the  next,  resulting  in  good penetration of elastomeric material between the wires. The closure of the cord is maintained in the subsequent heat   cycles,   owing   to   the   memory   degradation characteristics imparted to the wire.     The invention is particularly suitable for fabrics forming  belt  layers  and  casing  plies  in  pneumatic tyres.

Title: Electronically controlled weapons range with return fire
Inventor: MUEHLE ERIC G
IPC: F41G3/26
Filed: 1997-04-24
Abstract: A weapons training range provides a simulated weapons use scenario including return fire. A microprocessor select branches from a multi-branch program and causes an image projector to project subscenarios on a display screen visible to a participant. In response to the subscenarios, the participant fires at projected threats. Return fire simulators positioned behind the display screen return fire toward the participant. Obstructions are placed in the weapons range to provide cover for the participant. A video camera and X-Y position sensor identify the X-Y location of the participant and try to detect exposed portions of the participant. Based upon the identified X-Y location and any detected exposed portions the microprocessor aims the return fire simulators to provide simulated return fire. To simulate real world aiming, the microprocessor induces time-based and response-based aiming errors. Additionally, the microprocessor may aim the return fire simulators at objects in the participation zone to produce deflected fire that may also strike the participant.
Patent CA-2258674-A1 (CA)
Inventor: TIEMANN JEROME JOHNSON
IPC: H04B1/7107
Filed: 1997-07-03
Abstract: A direct sequence spread spectrum receiver samples an incoming signal and translates the signal to an IF signal. The IF signal is sampled ans stored in memory (192, 194). In one embodiment, the memory consists of two memory banks which alternately receive sample segments. During a write period to one of the memory banks, the other memory bank supplies its output to a processor (70). This continues in a ping-pong manner. In another embodiment, a single memory bank is filled and read as necessary, the receiver ignoring incoming signal until the processor has completed processing the sample available at the output of the memory. Such a receiver is useful in global positioning satellite (GPS) signal processing where the incoming signal contains several satellite transmissions encoded with CDMA  encoding.

Patent CA-2268759-A1 (CA)
Inventor: LUCEY PAUL
IPC: G02B23/24
Filed: 1997-09-30
Abstract: A variable-focus variable-magnification optical coupler is provided, for coupling an endoscope to a variety of different cameras having image planes at different positions while maintaining "true-zoom" functioning of the optical coupler. By "true-zoom", it is meant that the focal length of the optical coupler's lens system can be varied without having the image out of focus.  That is, once an image is focussed with the optical coupler, the image remains in focus even when the size of the image is changed by a zoom lens of the coupler. In one embodiment, the optical coupler includes an adjustment mechanism which is actuated to move a focus lens and a zoom lens assembly together along the length of the coupler relative to a camera mount. In another embodiment, an adjustment mechanism moves a back focal lens relative to the camera mount to account for the different image plane of the camera.
