Title: Securing electronic transactions over public networks
Inventor: GANESAN RAVI
IPC: G06Q20/00
Filed: 2000-12-22
Abstract: An electronic message for transmission over a network, such as the Internet, is created by encrypting a first component with a first crypto-key, which is associated with a first network entity, such that the encrypted first component can be decrypted by only the first network entity. The first crypto-key could, for example, be a symmetric crypto-key known only to the first network entity or the public non-symmetric crypto-key of a private-public non-symmetric key pair, where the private non-symmetric crypto key is known only to the first network entity. A second component, which is different than the first component, is encrypted with a second crypto-key, which is associated with a second network entity, such that the encrypted second component can also be decrypted by the first network entity. The second crypto-key could, for example, be a symmetric crypto-key known to both the first and second network entities or the private non-symmetric crypto-key of a private-public non-symmetric key pair of the second network entity, where the public non-symmetric crypto key is known to the first network entity. The encrypted first and second components are combined to create the electronic message.

Abstract: An electronic coin validator for connection to a payphone chassis is described. The validator includes a coin passageway having at least one coin sensor, power circuitry for connection to payphone chassis power lines and connected to the coin sensor, a validator line balance circuit connected to the power circuitry, at least one coin signal line for connection to the payphone chassis, at least one coin value buffer, and a control means. The control means processes signals from the sensor to validate coins, adjusts the count in the coin value buffer when a coin is validated, and readjusts the count when corresponding coin credit signals are generated for transmission. The validator line balance circuit has an output for connection to the payphone chassis, and equalizes the loading on the telephone lines to minimize impedance fluctuations. Consequently, coins may be validated and accepted by the electronic coin validator as coin tones are being generated and transmitted by circuitry of the payphone chassis to a central office.

Patent CA-2335307-A1 (CA)
Inventor: BURTON LEE A
IPC: G06F12/08
Filed: 1999-04-13
Abstract: A split directory-based cache coherency technique utilizes a secondary directory in memory to implement a bit mask used to indicate when more than one processor (16) cache in a multi-processor computer system (60) contains the same line of memory (50) which thereby reduces the searches required to perform the coherency operations and the overall size of the memory (50) needed to support the coherency system. The technique includes the attachment of a coherency tag (106) to a line of memory (104) so that its status can be tracked without having to read each processor (16) cache (102) to see if the line of memory (104) is contained within the cache (102). In this manner, only relatively short cache coherency commands need be transmitted across the communication network (68) (which may comprise a Sebring ring) instead of across the main data path bus thus freeing the main bus from being slowed down by cache coherency data transmissions while removing the bandwidth limitations inherent in other cache coherency techniques. The technique disclosed may be further expanded to incorporate the bus lock capability of bus-based systems compatible with the requirements for multi-processor synchronization.
Patent CA-2335590-A1 (CA)
Inventor: PEARLMAN EUGENE S
IPC: C12Q1/68
Filed: 1999-04-30
Abstract: A method of pipelining a disease specific diagnostic algorithm on an n-bit data word stored in a memory whereby the n-bit data word is divided into clinical tests describing ranges of normal values. Then, each of the clinical tests of the n-bit data word is read out from memory. Upon receiving a first of the results of the clinical tests, the result is compared with the normal value and the detection algorithm is computed based on the first result. This results in continuation with the next test if positive or terminate if negative. The above-steps are repeated recursively until all of the required test in the diagnostic algorithm are computed to provide the complete diagnosis of a disease.

The memory contains an operating program that is able to perform at least one operation (h). In order to prevent unauthorized access to the data (x) processed with the operation (h), both said data and the operation (h) itself are disguised. The disguising of the data (x) and the operation (h) is coordinated such that the disguised operation (h R1R, h R1R2) generates either the output data (y) of the undisguised operation (h) or disguised output data (y ~ R2) from which the output data (y) can be determined.

Abstract: An analytical rotor (10) for separating cellular components from a biological sample includes a plurality of internal chambers and passages for combining the cell-free sample with one or more reagents and distributing the sample to a plurality of individual test wells (92). The chambers and passages necessary for separating cellular components from a sample such as whole blood include a measuring chamber (40), an overflow chamber (44), a separation chamber (60), and a reagent chamber (80). The measuring chamber (40) and overflow chamber (44) have capillary dimensions so that an initial volume of whole blood partitions therebetween, with the measuring chamber filling first to provide a preselected volume. The separation chamber (60) is located radially outward from both the measuring chamber (40) and the reagent chamber (80) so that spinning of the rotor causes both the reagent and the measured blood volume to flow outward into the separation chamber (60). A collection chamber (90) is formed to receive the plasma from the separation chamber (60). Further spinning of the rotor causes the plasma to flow radially outward into a plurality of test wells (92) formed around the periphery of the collection chamber (90). Testing of the separated plasma volumes may be performed without removing the plasma from the rotor.

Title: System and method for reprogramming individual items in a barcode printer's flash memory
Inventor: BRAZIER GARY E
IPC: G06K1/12
Filed: 2001-07-31
Abstract: The system and method of the present invention allows the reprogramming of a flash memory in a barcode printer under the control of a host computer to permit reprogramming of selected, individual items in the flash memory without the need to reprogram items that can be changed but are to remain unchanged. The host computer operating in accordance with a control program communicates to the barcode printer a number of commands executable by the printer for reprogramming selected items including an application file, a font file and/or a print format file stored in the printer's flash memory. The commands include an erase command for erasing selected sectors in the flash memory of the barcode printer and a program command for reprogramming individual items in the flash memory. The barcode printer is responsive to each command as it is received for executing the command to reprogram individual items in the flash memory. After executing or attempting to execute a command, the barcode printer communicates to the host computer an acknowledgement of the command indicating a successful completion thereof or a status message if an error has occurred.

An elevation L1, measured between the elevated portions and the flat bottoms, is lesser than an overall height L2, measured between the elevated portions and the peripheral flat flange. The elevated portions the flat bottoms and the peripheral flat flange are parallel to each other. The insulated glazing panel comprises a pair of glazing panels. The pair of glazing panels is joined along internal confronting surfaces of the peripheral flat flanges by a sealing strip. The latter is interposed and adhesively secured to the internal confronting surfaces of the peripheral flat flanges. Thus, an undivided airtight chamber is formed by the two glazing panels which are held at a predetermined distance equal to a thickness L3 of the sealing strip, compounded with two overall heights L2.
