IPC: A61B5/08
Filed: 1997-06-25
Abstract: A gain control method for providing a gain controlled signal representative of a periodic physiological parameter of a patient includes providing a signal characteristic of the periodic physiological parameter. The periodic physiological parameter includes a plurality of periodic cycles. Gain of the signal is updated only once per periodic cycle following detection of a periodic event. The updating is performed by monitoring an amplitude of the signal between detection of periodic events and comparing the amplitude to a gain control amplitude threshold. Gain of the signal is updated as a function of the comparison. Further, gain is updated following expiration of a predetermined period of time if a periodic event is not detected within the predetermined period of time. The physiological parameter may be respiratory effort. An apparatus for providing such gain control is also provided.
Patent CA-2259234-A1 (CA)
Title: Coin discrimination apparatus and method
Inventor: NEUBARTH STUART K
IPC: G07D5/00
Filed: 1997-06-27
Abstract: A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or mare frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties.  All frequency components of the magnetic held are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters. In one embodiment, a sensor having a core, preferably ferrite, which is curved, such as in a U-shape or in the shape of a section of a torus, and defining a gap, is provided with a wire winding for excitation and/or detection. The sensor can be used for simultaneously obtaining data relating to two or more parameters of a coin or other object, such as size and conductivity of the object. Two or more frequencies can be used to sense core and/or cladding properties. Objects recognized as acceptable coins, using the sensor data, are diverted by a controllable deflecting door, to tubes for delivery to acceptable coin bins.

Abstract: A personal toll billing service that provides a caller in a multi-user, single subscriber line environment, with the ability to dial a direct toll call, be prompted to enter identification data (PIN, voice) and have the call routed to the appropriate destination in the telephone network. At the end of a billing period the pre-subscribed long distance carrier (IEC) sends a bill directly to the specific caller for only their calls and not for the toll calls made by other callers on the same subscriber line. The personal toll billing service is initially enabled by activating the subscriber line for the personal toll billing service. If a toll call is made a message is formed incorporating identification data (PIN or voice signature) of the caller on the subscriber line, the caller being subscribed to a predetermined IEC (i.e. a specific long distance carrier). The final step required prior to routing the call is to translate the identification data of the caller in the message to a charge number and a carrier selection representing the predetermined IEC subscribed to by the caller. The toll call is then routed through the telephone network using the carrier selection and the charge number.

Patent CA-2272299-A1 (CA)
Inventor: SAIDI MOHAMED-YAZID
IPC: H01M4/62
Filed: 1997-11-21
Abstract: The present invention provides a novel composition and method for preventing decomposition of one or more electrochemical cell components comprising an electrode having an active material, and an electrolyte. The method of the invention effectively blocks decomposition of a lithium metal oxide cathode active material, and particularly lithium manganese oxide (LMO, nominally LiMn O). Such decomposition is prevented by including in the cell a basic compound which forms an electron donor species in the electrolyte solution; and by neutralizing at least a portion of the acid by reacting the donor species with the hydrogen-containing acids thereby preventing decomposition of the lithium manganese oxide by the acid. The preservation of the lithium manganese oxide prevents degradation of other cell components by other mechanism.

Patent CA-2289128-A1 (CA)
Inventor: SHIN DO B
IPC: H03F1/32
Filed: 1999-11-09
Abstract: The invention relates to a low cost feed forward RF power amplifier arrangement for amplifying an RF input signal using a main power amplifier operating as a class A/B amplifier. The method and apparatus modify the input signal to the main amplifier to compensate for the distortion added by the main power amplifier. The circuit provides for injecting a delayed version of the input signal, through a fixed gain-phase circuity, at a point whereby the resulting signal is amplified by the error amplifier of the second loop. A digitally controlled processor iteratively modifies various phase and gain controls to adjust the output of the amplifier.      Different gain and phase control lines are iteratively updated at different rates.
