Patent CA-2180736-A1 (CA)
Title: Noncontact active temperature sensor
Inventor: FRADEN JACOB
IPC: G01J5/20
Filed: 1994-12-19
Abstract: A noncontact active infrared sensor (1) for mea-suring the temperature of a remote object is provided with bifurcated sensing elements (6, 7). A first element (6) is uniquely exposed to the remote object, thereby establishing a radiative flux. A second element (7) is configured in the same local environment as that of the first element (6) but isolated from radiation from the re-mote object. The heat transfer of both elements (6, 7) is compared and that component of heat transfer corre-sponding to flux with the remote object is isolated and converted into a temperature signal. The sensor system advantageously incorporates individual thermal control units (34, 38) onto both sensor elements (6, 7) to accu-rately control salient thermal transfers while thermally decoupling the sensor elements (6, 7). This provides for a more accurate reading of the temperature of the remote object.

Title: Multichannel apparatus for epidural spinal cord stimulation
Inventor: HOLSHEIMER JAN
IPC: A61N1/34
Filed: 1995-01-23
Abstract: Apparatus for multi-channel trans-verse epidural spinal cord stimulation uses a multi-channel pulse generator driving a plurality of electrodes mounted near the distal end of a lead. These electrodes are mounted in one or more lines gen-erally perpendicular to the lead axis, and have a planar surface along one surface of the lead. The lead is implanted ad-jacent to spinal cord dura mater with the electrodes transverse and facing the spinal cord. Pulses generated by the pulse gener-ator for each channel are normally simul-taneous, of equal amplitude and of equal duration however, the pulse generator is arranged such that pulses for each channel ran selectably alternate in time can se-lectably be of unequal amplitude, or both. The changes in pulse timing and magni-tude permit shifting the electrical stimu-lation field and the resulting paresthesia pattern after installation to accommodate improper lead placement or postoperative dislocation and to minimize unwanted mo-tor responses.

Filed: 1996-10-29
Abstract: A method for packaging cans or tubes continuously delivered from a production installation to pick-up elements, which are moved in steps, of an intermediate station. A gripper device brings the cans or tubes in groups according to the desired number of pieces in a packaging layer to a delivery station. Each can or tube is deposited into a support element, after which the cans or tubes are pushed together out of the support elements into a loading station. The cans or tubes are placed at equal distances into the pick-up elements, wherein individual support elements are placed apart from each other at a predetermined distance. The cans or tubes are then deposited into the support elements at distances predetermined by the pick-up elements. The support elements are subsequently moved together until they touch each other, whereupon the cans or tubes are then pushed into the loading station. This method allows the use of the same apparatus for different can diameters with minimal changing effort.

Patent CA-2196617-A1 (CA)
Title: Optical encoder with variable-phase sinusoidal output
Inventor: BLOECHLE WALTER
IPC: G01D5/26
Filed: 1997-02-03
Abstract: The general purpose of the invention is to produce a sinusoidal output wave whose phase shift will be proportional to the angular shaft position. A single rotation of the shaft produces a large number of cycles of the sine wave. The amplitude and frequency of the sine-wave output are both constant, and the sine-wave output continues at the same amplitude and frequency even when the shaft angle is stationary. A single source of light is used to illuminate a large number of closely spaced detectors, and the light intensity is constant in time. The light passes through an optical disk with a pattern of alternately light and dark radial lines on it, arranged in a circumferential array, which modulate the transmitted light to produce a sinusoidal pattern of illumination of an array of detectors. The array of closely-spaced detectors is scanned serially at high speed to produce a continuous stream of analog output data which emulates the output produced by a resolver or LPDT (see Ref. 1).  A distinguishing characteristic of the device is that it is not necessary, or even desirable, to digitally sample the output signal as is done in Ref. 2.  Instead, the output signal is processed in its' original analog form by an ASIC (Application Specific Integrated Circuit) which is generic in nature, and not specifically designed for optical encoders. A second distinguishing characteristic of the device is that a single optical source of illumination can be used at constant intensity, which greatly simplifies the optical characteristics of the device, while other devices of this type typically require pulsing and/or time phase-shifting of multiple optical sources relative to each other (see Ref.  3).
