Patent CA-2188075-A1 (CA)
Inventor: CHAVEZ DAVID LEE JR
IPC: H04W36/12
Filed: 1996-10-17
Abstract: Utilizing a bridged line appearance feature in a switching system to allow additional individual PCS systems to be added as the number of wireless sets increases. For each wireless set, a bridged line appearance is administered in the switching system having a group of shared line appearance telephone links where the number of telephone links in each group is equal to the number of individual PCSsystems. When the switching system receives a call for a particular wireless set, the switching system signals the incoming call on each telephone link that is part of the shared line appearance group for that particular wireless set. The PCS system onwhich the particular wireless set is presently registered responds to the incoming call signal by establishing a call between the particular wireless set and the incoming call. During the call, if the wireless set physically moves and establishes communications with a base station of another PCS system, the other PCS system becomes active on the shared line appearance telephone link assigned to the wireless set on the other PCS system. The original PCS system becomes inactive on the shared line appearance telephone link associated with the wireless set when the wireless set transfers itself to the other PCS system. This allows the wireless set to be "handed off" to the other PCS system without the PCS systems having to directly implement the "handoff" operation.

Title: Medical device employing multiple dc accelerometers for patient activity and posture sensing
Inventor: SHELDON TODD J
IPC: A61N1/365
Filed: 1996-02-23
Abstract: A method of and apparatus for determining the physical posture of a patient's body, having a superior-inferior body, axis, an anterior posterior body axis and a lateral-medial body axis, in relation to earth's gravitational field. A medical device having first, second and optionally, third DC accelerometers having sensitive axes mounted orthogonally within an implantable housing is adapted to be implanted with the sensitive axes generally aligned with the patient's body axes. Each DC accelerometer generates DC accelerometer signals having characteristic magnitudes and polarities on alignment of the sensitive axis with. against or normal to earth's gravitational field and DC accelerometer signals of varying magnitudes and polarities when not so aligned. Body position may be determined through comparison of the magnitudes and polarities of the DC accelerometer signals with the characteristic magnitudes and polarities. A patient activity signal may also be determined from the frequency of body movements recurring over a time unit effecting magnitude changes in the DC accelerometer signals within a certain range of magnitude and frequency. The activity and body position signals may be stored and or used to monitor and effect the delivery of a therapy to the patient, e,g. by controlling the pacing range of a rate responsive pacemaker.

Title: Cooking with spent liquor pretreatment of cellulose material
Inventor: HENRICSON KAJ O
IPC: D21C7/00
Filed: 1995-08-30
Abstract: A method and continuous digester system provide for a high Na2S concentration in the beginning of the cooking of comminuted cellulosic fibrous material to produce cellulose pulp, providing a more selective cooking and potential to lower cooking kappa. Two different streams of spent (e.g. "sulfurous" and "black") liquor are removed from different screens associated with continuous digesters. The spent liquor removed from the uppermost screen has a relatively high effective alkali and Na2S concentration. The second spent liquor, removed from the second screen, has effective alkali and Na2S concentrations which are at least 25 % less than for the first spent liquor. The first spent liquor is circulated to an impregnation vessel, or other part of a chip feed system, to enhance the amount of sulfur present at the beginning of the cooking stage in the digester. The second spent liquor may be used in a number of ways, including -- with or without first passing it through a flash tank -- circulating it to a chip slurrying system for slurrying the chips so that they can be fed to the digester. The steaming and slurrying system may include only an unpressurized chip bin, chip feeder, slurrying vessel, and high pressure feeder, thus being simpler than conventional constructions.

Title: Optical equalizer and optical amplifier and wavelength multiple optical transmission apparatus using optical equalizer
Inventor: SHIBUYA TAKASHI
IPC: H01S3/067
Filed: 1997-04-22
Abstract: There are provided a plurality of etalon filters arranged in concatenation, a light output portion for outputting a light to the etalon filters, and a light input portion to which a light transmitting the etalon filters is inputted, and the plurality of etalon filters have mutually different free spectrum regions.  A plurality of etalon plates applied with semipermeable films to both surfaces of a thin glass plate and having mutually different periods and amplitudes are cascade-connected.  By combining a plurality of etalon films having different characteristics with one another, it is possible to realize an optical equalizer having low loss polarized light dependency and capable of compensating optional gain wavelength dependency.  By using such an optical equalizer as a repeater by combining the optical equalizer with an optical amplifier, a level difference caused by the difference of the gain among wavelengths of optical signals is neither produced in a wavelength multiple optical transmission apparatus.        It is possible to realize an optical equalizer for compensating gain wavelength dependency of an optical fiber amplifier, which compensates for optional gain wavelength dependency and has low loss polarized light dependency.

Patent CA-2212812-A1 (CA)
Inventor: BOWMAN JOHN C
IPC: H04N5/272
Filed: 1996-08-02
Abstract: The present invention is useful in taking a visible light image for identification and other purposes without the requirement of a photobooth, regardless of the background of the visible light image. The original background of the visible light image is replaced with a preselected background. Two IR images with different intensities of IR illumination in the foreground and background regions of the scene, respectively, are compared to produce a difference image of light intensity different between corresponding pixels of the two images. A binarized image is generated by binarizing the difference image with respect to a predetermined threshold value .theta.. A connectivity constraint is used to generate a binary mask from the binarized image, then a gray-scale mask is produced by multiplying the binary mask times a preselected modulation function of the difference image. Warping the gray-scale mask produces a transformed mask. Finally, the background-replaced visible light image is generated by blending the transformed mask with the visible light image, and replacing the original background with the preselected background.

Title: Auxiliary lifting forks for extended-length pallet trucks
Inventor: METZGER GERALD R
IPC: B62B3/06
Filed: 1996-03-06
Abstract: An improved pallet truck, having an extended length pair of forks (110) capable of supporting multiple, side-by-side pallets which may be raised well above the floor to assist an operator in an order selection operation, includes a first fork lifting mechanism (70) connected to one end of a pair of primary forks (60). A pair of load wheels (80) are mounted on levers at another end of the forks (60) and are mechanically connected to the first fork lifting mechanism (70) which causes the other end of the primary forks (60) to be raised from a lower level to an upper level simultaneously with the raising of the first end thereby to maintain the primary forks (60) level while lifting the maximum capacity of the truck. A pair of secondary forks (110) are mounted above the primary forks (60) and are movable from a nested position with respect to the first forks (60) to a raised position by a second fork lifting mechanism (120) carried by the primary forks (60). The ends of the secondary forks (110) are supported by a pair of hydraulic cylinders (180) attached between the secondary forks (110) and the primary forks (60), thus providing support and rigidity to the secondary forks (110) while they are in a raised position.
