Patent CA-2211910-A1 (CA)
Title: Fingerprint-acquisition apparatus for access control; personal weapon and other systems controlled thereby
Inventor: LUBARD STEPHEN C
IPC: G07C9/00
Filed: 1996-01-29
Abstract: At a first end of an optic-fiber prism assembly are fiber terminations to contact a relieved surface, e.g. finger (stabilized by a handgrip). In a region where fiber diameter is essentially constant with longitudinal position, light enters the prism, crosses the fibers and enters individual fibers through their sidewalls, lighting the terminations. To allow crosslighting of the assembly, the fiber-optic numerical aperture (NA) is small: preferably not exceeding one-half. Due to fingerprint etc. detail, fractions of light pass along the fibers; at the assembly second end a detector responds with an electrical-signal array based on the surface relief.  The signals are processed to check finger etc. identity and applied to control access to a personal weapon, other equipment, facilities, data, or a money service. FTIR ("frustrated total internal reflection") bright- and dark-field versions have various benefits. For use of small, low-cost detectors - and/or internal-mirror versions that light the finger straight-on - the assembly has a separate element, e.g. a <u>high</u>-NA fiber-optic taper with extramural absorption or "EMA" material (no entry light crosses it). For a weapon, a unitary antibypassing module (which matches a weapon port, and must be present) holds part of the access-control <u>and</u> firing systems. Bullets etc. fire only on a special signal from the module.

Patent CA-2213855-A1 (CA)
Title: Slope, drift and offset compensation in zero-if receivers
Inventor: DENT PAUL W
IPC: H03D7/16
Filed: 1996-03-01
Abstract: A method for processing a signal modulated with information symbols to account for an additive offset and slope is disclosed. First, an initial estimate of offset and slope is made and hypotheses of all possible values of a sequence of one or more information symbols are then made.      For each of said hypotheses, the associated data symbol sequence is used to make an improved estimate of offset and slope and the improved estimate of offset and slope are stored against each of the hypotheses. For each hypothesis, the improved estimate of offset and slope is used in calculating an expected signal value and a mismatch between a sample of the modulated signal and the expected value is computed. The hypotheses are then sequentially extended by one symbol, the slope and offset estimates are updated and the mismatches are accumulated to form a path metric value for each extended hypothesis, and resolving between said hypotheses based on said path metric values using a Viterbi Sequential maximum Likelihood Sequence Estimation process to produce a most likely hypothesis of said modulated information symbols substantially unimpaired by said additive slope and offset.

Patent CA-2215697-A1 (CA)
Inventor: GAWRYL MARIA S
IPC: C07K14/805
Filed: 1996-03-22
Abstract: A method for producing a stable polymerized hemoglobin blood-substitute from blood characterized in the use of a chromatographic column, is disclosed. The method of this invention includes mixing blood with an anticoagulant to form a blood solution, washing the red blood cells in the blood solution and then separating the washed red blood cells from the white blood cells. This method also includes disrupting the red blood cells to release hemoglobin and form a hemoglobin solution, which is then treated by high performance liquid chromatography to form a hemoglobin eluate. The hemoglobin eluate is then deoxygenated, contacted with a first reducing agent to form an oxidation-stabilized deoxygenated hemoglobin solution, and mixed with a cross-linking agent to form a polymerization reaction mixture, which is then polymerized. The polymerized hemoglobin solution is then diafiltered with a physiologic solution and with a reducing agent, whereby the polymerized hemoglobin solution is made physiologically acceptable, and whereby the reducing agent scavenges oxygen, to form a stable polymerized hemoglobin blood-substitute, which is then packaged and stored in an atmopshere substantially free of oxygen.  Compositions made by the methods are also disclosed, as are methods of therapeutically, or prophylactically, treating a vertebrate to increase tissue oxygenation, or prevent oxygen depletion, in tissue of the vertebrate.

Title: Speaker recognition device
Inventor: HATTORI HIROAKI
IPC: G10L17/06
Filed: 1998-01-22
Abstract: A speaker recognition device is designed to actualize speaker recognition which is capable of coping with an increase of enrolled speakers with a small amount of processing and to provide a high precision of speaker recognition regardless of a variety of disturbances. Herein, sound analysis is performed on input voice data of an input speaker to produce an input pattern representing sound characteristics. The device stores standard patterns (e.g., time series of sound parameters or HMM parameters) with regard to enrolled speakers in a form of a tree structure which is constructed by nodes mutually connected together from a root to leaves. Similarity calculations are performed in a direction from the root to the leaves of the tree structure to produce similarity scores between the input pattern and the standard patterns respectively. An order is determined for the calculated similarity scores from the highest to the lowest. In addition, a similarity score is calculated for a designated speaker who is specified by speaker information input to the device. If a place of the order set for the designated speaker belongs to a prescribed range of places of the order, the device makes a decision of acceptance that the input speaker coincides with the designated speaker. If not, the device makes a decision of rejection that the input speaker feigns to be the designated speaker.

Abstract: A two-stage cell routing filter mechanism employs a customer premises associated flag bit field (133) in ATM data cells being serially transmitted from a host digital terminal's data transport path through an optical fiber (22) to a downstream optical network unit (23) associated with a plurality of customer premises equipments (40). The first stage of the cell routing filter is comprised of a look-up table (LTU) and an associated comparator mechanism.  The state of each bit of the flag field of an ATM cell preamble will indicate whether or not the ATM cell is intended for the customer premises equipment associated with the bit. A downstream optical network unit contains an associated set of ATM cell filters associated with customer premises equipment. Each customer equipment cell filter examines a given bit position in the flag field portion of each received ATM cell preamble, to see whether the flag field bit of the preamble of the received ATM cell is set to a prescribed bit value (e.g. one) - indicating a customer channel request.

Patent CA-2233841-A1 (CA)
Inventor: TOLTZMAN RANDALL R
IPC: H04B1/3827
Filed: 1996-10-03
Abstract: A portable wireless communications device such as a telephone handset (10, 110) having a vertically corrected antenna module (34, 134) pivotally secured to the handset (10, 110) for rotation about a first pivot axis (40, 140). The antenna module (34, 134) can be rotated into a predetermined orientation, independent of handset orientation. An antenna (24, 124) mounted on the module (34, 134) is oriented vertically when the module (34, 134) is in the predetermined orientation. When the antenna module (34, 134) is rotated for use, a mechanism incorporated in the module (34, 134) support structure automatically rotates the antenna module (34, 134) about a second pivot axis (190) which is substantially perpendicular to the first (40, 140). This second rotation places the antenna (24, 124) at an angle that compensates for tilting of the handset (10, 110) during use about an axis parallel to the second axis (190), or along the first (40, 140). That is, the antenna (24, 124) is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a speaker and microphone (26, 28) for use.
