Patent CA-2310151-A1 (CA)
Inventor: SCHNEIDER YADA
IPC: G06K19/00
Filed: 2000-05-30
Abstract: A card-based system electronically transfers funds in real time. A customer card stores digital data representing a unique customer account number associated with a unique, remotely located customer account having at least one vendor-associated subaccount. A merchant terminal having a merchant IP address designating a unique merchant is affiliated with at least one unique vendor for transmitting to a system control center customer transaction data including the merchant IP address, the customer account number read from the customer card and account adjustment data designating either the value of a credit to be added to the vendor-associated subaccount reflecting a customer pre-payment or the value to be subtracted from the vendor-associated customer subaccount reflecting a customer purchase.      The system control center maintains a vendor account database and a customer account database. The customer account database associates each customer account number with the unique customer account number, stores the subaccount credit balance corresponding to the specified vendor, receives the customer transaction data transmitted by the merchant terminal, adjusts the customer subaccount value up or down in response to the customer transaction data, transmits to the merchant terminal customer account status information and adjusts the vendor account database to reflect credits resulting from vendor-associated customer transactions.

Title: Telephone technician's remote assist apparatus and method
Inventor: BUTLER MYRON C
IPC: H04M3/30
Filed: 2000-07-10
Abstract: A telephone technician's remote assist apparatus connects into a telephone line to be tested by the technician from a remote location. Control signals are sent from the remote location to the remote assist apparatus over the same pair of wires of the telephone line under test. A particular control signal encoding includes two consecutive leading star (**) dual-tone multi-frequency tones. The remote assist apparatus opens the telephone line in response to at least one control signal, and the apparatus preferably automatically restores the line after a predetermined time so that the subscriber is not left disconnected. The particular control signal encoding and the automatic restoring features can be implemented without using the same pair of wires under test. Thus a method for use in testing a telephone line can include controlling by using the same pair of wires under test, but a method can also include using the particular type of encoded control signal and/or the automatic restoring features without using the same pair of wires under test.

Title: Sex-specific insemination of mammals with low number of sperm cells
Inventor: SCHENK JOHN
IPC: A61D19/04
Filed: 1998-12-31
Abstract: Artificial Insemination is achieved for sexed mammalian offspring in a commercially practical manner and with dosages of insemination sperm which were not previously thought to be practical for commercial implementation. Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid (3) and other strategies which minimize stress on the sperm cells (18), and potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species. Improved collection systems (14) and techniques for the process are describeb so that commercial application of sperm samples as well as the resulting animals may now be achieved in the field.
Patent CA-2319311-A1 (CA)
Title: A secure database management system for confidential records
Inventor: HO ANDREW P
IPC: G06F21/62
Filed: 1999-01-21
Abstract: A system (100) for managing sensitive data is described. The system prevents a system administrator from accessing sensitive data by storing data and identifier information on different computer systems. Each query is encrypted using two codes, the first code readable only by an identifier database (128) and a second code readable only by a data access database (152). By routing the data path from a source terminal (104) to the identifier database (128) which substitutes an internal ID, then to the data access database (152) and back to the source terminal (104), data security is significantly improved.

Patent CA-2335214-A1 (CA)
Inventor: MATTER DANIEL
IPC: G01D5/249
Filed: 2001-02-09
Abstract: An apparatus for capacitively determining a position of a counter wheel (1) in a wheel counter mechanism has fixed electrodes (3, 3') at a distance from the counter wheel (1). Extending over the circumference of the counter wheel (1) are a sequence of measurement electrodes (12, 12', 12" ), and electrically nonconductive sections (13, 13') arranged between said measurement electrodes. This means that it is possible to detect either a high or a low capacitance value, that is to say a binary value of either 0 or 1, for each position of the counter wheel and for each fixed electrode. According to the number of fixed electrodes for each counter wheel, these binary values can be combined to form a binary representation of any desired number characterizing the current position of the counter wheel (1).

Title: Chain driven belt discharge apparatus and method
Inventor: WILKERSON LEE
IPC: B60P1/38
Filed: 2000-05-11
Abstract: A conveyor apparatus (10) for discharging bulk flow material (14) from a trailer (57) includes a drive sprocket assembly (34) at one end (12), driven by a motor (38), with a free, idler sprocket assembly (24) at the other end (11). Endless loop drive chains (40, 42) engaged over the two sprocket assemblies are spaced apart by transverse spacer bars (44) attached between the chains. An endless loop conveyor belt (52) is received loosely over the endless loop drive chains, covering the chains but leaving slack in the belt.  When the motor turns the drive sprocket assembly, advancing the drive chains and spacer bars, the weight of the bulk flow material holds the conveyor belt tightly down, against the chains and bars, creating friction to prevent slippage between the chains and the belt, thereby allowing the chains to advance the belt, and the bulk flow material thereon.
