Title: Method and apparatus for charging batteries
Inventor: FIELD ROBERT B
IPC: H01M10/44
Filed: 1997-02-28
Abstract: A charger for charging a rechargeable battery. The charger comprises a circuit for producing a charging current having a variable level and a control circuit for controlling the charging current.

Title: System and method for automatic area code updating
Inventor: SHAFFER SHMUEL
IPC: H04M1/27485
Filed: 1998-10-27
Abstract: A system for updating area code information in predetermined telecommunications devices and networks as newly created area codes are implemented.  Area code lists may be updated automatically and without the need for human intervention or manual reprogramming.  A message receiving unit monitors the telephone connection and determines whether a "new area code" message is being transmitted by the telephone company central office or carrier.  A message decoding unit decodes the transmitted message into a required format for a predetermined device.  An update unit enables the area code lists to be automatically updated in the predetermined device if a list comparator determines that the area code does not exist in the lists.

Title: Optical disc, recording apparatus, a computer-readable storage medium storing a recording program, and recording method
Inventor: TSUGA KAZUHIRO
IPC: H04N21/2368
Filed: 1998-12-15
Abstract: An optical disc records video objects that are obtained by multiplexing a video stream and an audio stream. The audio stream is an arrangement of a plurality of sets of audio frame data. Each video object unit in a video object is an arrangement of packs that have a different payload. The video stream and audio stream are divided using a predetermined size and the resulting data divisions are arranged into packs.      At least one video object unit includes packs where stuffing bytes or a padding packet is arranged with part or all of a set of audio frame data so that the boundary with the next video object unit corresponds to a boundary between a boundary between sets of audio frame data. Since the boundary between video objects is made to match a boundary between sets of audio frame data, partial deletes that are performed with a video object unit as the smallest unit will not result in unnecessary parts of data remaining on the optical disc.

Patent CA-2258174-A1 (CA)
Inventor: CHIU TAK-MING
IPC: G01N33/487
Filed: 1997-06-13
Abstract: In the method of the invention, in vitro proton magnetic resonance spectroscopy (MRS) is employed to determine the measurable ethanol concentration in ethanol-treated erythrocyte and plasma samples of occasional and heavy drinkers. An erythrocyte to plasma ethanol concentration ratio (102122) is determined based upon the MRS measured erythrocyte concentration. Erythrocyte to plasma ethanol concentration ratios are greater for heavy drinkers (a subset of alcohol tolerant individuals) as compared to the ratios for occasional drinkers (non-tolerant individuals) when erythrocyte ethanol concentration is determined by MRS. The method of the present invention discriminates between alcohol tolerant individuals and alcohol non-tolerant individuals based upon the magnitude of the erythrocyte to plasma ethanol concentration ratio obtained (124, 126).

Patent CA-2263697-A1 (CA)
Title: Nuclear waste separator
Inventor: OHKAWA TIHIRO
IPC: H05H1/46
Filed: 1999-03-16
Abstract: A method and system for separating radioactive waste containing volatiles, into light ions and heavy ions, includes a loader/transporter for transferring the waste into a high vacuum environment in the chamber of a plasma processor. During this transfer, gases of the volatiles are released from the waste, collected in a holding tank, and subsequently ionized in the chamber. As the volatiles are ionized, the ions are directed by a magnetic field into contact with the waste to vaporize the waste. The waste vapors are then ionized in the plasma processor chamber to create a multi-species plasma which includes electrons, light ions and heavy ions. Within the chamber, the density of the multi-species plasma is established to be above its collision density in order to establish a substantially uniform velocity for all ions in the plasma. A nozzle accelerates the multi-species plasma to generate a fluid stream which is directed from the chamber toward an inertial separator. A magnetic field in the inertial separator effectively blocks electrons in the stream from entering the separator. On the other hand, the inertia of the various ions in the stream carry them into the separator where they are segregated into light ions and heavy ions according to their atomic weights. After segregation, the heavy ions are vitrified for subsequent disposal.
Patent CA-2264171-A1 (CA)
Title: Method for crediting or recrediting a data card with a given amount
Inventor: RITTER RUDOLF
IPC: G06Q20/36
Filed: 1997-08-21
Abstract: The invention pertains to a method for crediting or recrediting a SIM card (subscriber identity module) for a mobile radio telephone (6) with a given amount (28). The SIM card comprises a chip provided with a memory element (11). The amount is stored in said memory element (11) and decreases as the mobile radio telephone is used. In order to credit or recredit a SIM card, the user must possess a memory board (13) payable in advance. The memory board (12) has a code area (14) covered with a nontransparent detachable film (22).  A code (15) appears upon detaching the film (22). The SIM card (7) and memory board (13) holder dials a service number from a telephone (6, 8), the calling party thereby being connected to a data bank (17) where all codes allocated to memory boards (15) and the corresponding amounts (12) are recorded. The calling party is requested to input his code number into the telephone (6, 8) with which he is calling. Once entered, the code is compared with the code recorded at the data bank. As soon as the code (15) has been retrieved, a short message with the amount to be credited or recredited is temporarily recorded at the short message service center (18, 19). The amount (28) and the code (15) registered at the data bank (17) are then marked as depleted or erased. Next time the holder inserts his SIM card (7) into any mobile radio telephone and sets up a connection with the telecommunication network (9), said card will be credited or recredited with the amount (28) temporarily recorded on the basis of the prepared short message (20).

Title: Gas turbine meter
Inventor: SCHIEBER WILLIAM M
IPC: G01F15/075
Filed: 1998-01-21
Abstract: A gas turbine meter (20) includes a measuring cartridge (36) which has a measuring ro-tor (38) that rotates in one direction at a speed approximately proportional to the velocity of gas flowing through the meter (20) and a reference rotor mounted downstream of the measuring rotor (38) which rotates in the opposite direction from the measuring rotor. An inlet flow straightener (28) upstream of the measur-ing rotor causes gas to flow substantially axially within the meter, and a reference flow straight-ener mounted between the measuring rotor and the reference rotor also causes gas to flow substantially axially within the meter. A signal pro-cessor provides an indication of the accuracy of the gas turbine meter based on the quotient of a measuring signal, which is proportional to the speed of rotation of the measuring rotor, divided by a reference signal, which is proportional to the speed of rotation of the reference rotor.
