Title: Electrochemical biosensor test strip
Inventor: PRITCHARD G JOHN
IPC: G01N27/327
Filed: 1996-06-28
Abstract: An electrochemical biosensor test strip (1) that has a minimum volume blood sample requirement of about 9 microliters. The test strip has working (4) and counter (5) electrodes that are substantially the same size and made of the same electrically conducting material placed on a first insulating substrate (2). Overlaying the electrodes is a second insulating substrate (3), which includes a cutout portion (8) that forms a reagent well. The cutout portion exposes a smaller area of the counter electrode than the working electrode. A reagent for analysis of an analyte substantially covers the exposed areas of working and counter electrodes in the reagent well. Overlaying the reagent well and affixed to the second insulating substrate is a spreading mesh (13) that is impregnated with a surfactant. The small cutout portion of 4 millimeters by 4.2 millimeters, small mesh of 6 millimeters by 5.8 millimeters, and small amount of reagent, 4 microliters before drying, allow the test strip to analyze a whole blood sample of about 9 microliters.

Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned.   Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first  and second  data  streams  is  developed  by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into,  low and high,  frequency band components which are designated as a first and a second data stream respectively.       Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

Title: Speaker recognition system capable of accurately selecting inhibiting reference patterns by using small amount of calculation
Inventor: YAMADA EIKO
IPC: G10L17/12
Filed: 1998-01-28
Abstract: In a speaker recognition system, a tree-structured reference pattern memorizing unit has first through M-th node stages each of which has nodes and each of which memorizes a reference pattern of inhibiting speakers, the reference pattern of each of the nodes of (N-1)-th node stage representing acoustic features in the reference patterns of the predetermined ones of the nodes of N-th node stage. An analysis unit analyzes an input verification utterance and converts the input verification utterance into feature vectors. A similarities calculating unit calculates similarities between the feature vectors and the reference patterns of all of the inhibiting speakers. An inhibiting speaker selecting unit sorts the similarities and selects a predetermined number of inhibiting speakers. The similarities calculating unit calculates the similarities of the nodes of the first node stage and calculates the similarities of the nodes of the N-th node stage which are connected to a predetermined number of nodes of the (N-1)-th node stage selected, in order from one of the nodes of the (N-1)-th node stage having the highest similarities. The similarities calculating unit uses the similarities of the nodes of the (N-1)-th node stage for unselected ones except the predetermined number of ones.

Patent CA-2230400-A1 (CA)
Inventor: TROZZI MARK R
IPC: A63B57/00
Filed: 1998-04-30
Abstract: In a machine which automatically serves golf balls on a tee-like holder to a practicing golfer, difficulties arise in regard to sensing that the ball has been hit off the tee so the machine may respond by reloading the tee with another ball. The high-impact involved in the striking of the ball creates problems for sensitive or delicate weight sensors. Also moisture and dirt create malfunctions with infra-red ball presence sensors. In addition to reliability problems, the above sensors are expensive. In this invention, a flexible but durable tee with electrically conductive elements is surrounded by a conductive ring. When the golfer strikes the ball, the tee is deflected bringing the conductive elements of the tee in contact with the conductive ring, thus completing an electric circuit which signals the machine's processor(s) that the ball has been hit. Additional applications of this invention include an off level sensor, an acceleration or vibration sensor, and a passing object sensor.

Title: A method for performing a soft handoff
Inventor: KUMAR SARATH
IPC: H04W36/18
Filed: 1998-08-18
Abstract: The present invention increases the success rate of soft handoffs by enhancing the ability of a mobile-telephone to receive a handoff direction messa ge that identifies the traffic channel being assigned to enable a candidate base station to communicate with the mobile-telephone. Specifically, the aforementioned ability of the mobile-telephone is enhanced by using the candidate base station to transmit the handoff direction message on a communication channel belonging to the candidate base sta tion and being listened to by the mobile-telehone. In situations where signals transm itted from active set base stations have a low signal-to-noise ratio at the mobile-tel ephone, signals transmitted from the candidate base station may have a higher signal-to-noise ratio at the mobile-telephone. In these situations, the transmission of the HD m essages from the candidate base station increases the likelihood that a copy of the hand off direction message will be successfully received by the mobile-telephone, thereby enhancing the success rate of soft handoffs.
