Patent CA-2274635-A1 (CA)
Title: Apparatus for providing a nonlinear response
Inventor: PRAISWATER MICHAEL R
IPC: G06G7/28
Filed: 1997-11-17
Abstract: An amplifier which outputs a nonlinear function in response to a linear input. The nonlinear response is a piece-wise linear approximation. The circuit includes an op amp which outputs a ramping voltage and a series of stages which change the slope of the ramping voltage. As the output of the op amp reaches a particular breakpoint, an additional stage of the circuit is activated so as to change the slope of the output.      The new line segment has a new slope such that the combination of all these stages approximates a nonlinear response.

Patent CA-2286210-A1 (CA)
Title: Attenuated salmonella strain used as a vehicle for oral immunization
Inventor: GERSTEL BIRGIT
IPC: C12R1/42
Filed: 1997-12-11
Abstract: An attenuated strain of Salmonella typhimurium has been used as a vehicle for oral genetic immunization. Eukaryotic expression vectors containing the genes for .beta.-galactosidase, or truncated forms of ActA and listeriolysin - two virulence factors of Listeria monocytogenes - that were controlled by an eukaryotic promoter have been used to transform a S. typhimurium aroA strain. Multiple or even single immunizations with these transformants induced a strong cytotoxic and helper T cell response as well as an excellent antibody response. Multiple immunizations with listeriolysin transformants protected the mice completely against a lethal challenge of L. monocytogenes. Partial protection was already observed with a single dose. ActA appeared not to be a protective antigen. The strength and the kinetics of the response suggested that the heterologous antigens were expressed within the eukaryotic host cells following transfer of plasmid DNA from the bacterial carrier strain. Transfer of plasmid DNA could be unequivocally shown in vitro using primary peritoneal macrophages. The demonstration of RNA splice products and expression of .beta.galactosidase in the presence of tetracycline - an inhibitor of bacterial protein synthesis - indicated that the gene was expressed by host cells rather than bacteria. Oral genetic immunization with Salmonella carriers provides a highly versatile system for antigen delivery, represents a potent system to identify candidate protective antigens for vaccination, and will permit efficacious generation of antibodies against virtually any DNA segment encoding an open reading frame.

Title: Transparent printing blankets and methods of use
Inventor: AGNEW BROOKS A
IPC: B41N10/04
Filed: 1998-06-17
Abstract: Substantially transparent printing blankets are provided comprising a substantially transparent printing layer (11) disposed upon a substantially transparent support layer (12). The substantial transparency of such printing blankets permits off press introduction of knock-out areas. In certain embodiments, this is accomplished by disposing the support layer (12) of the printing blanket adjacent to a substrate which bears either an image to be printed or some other print transfer information (such as a negative) corresponding to the image. The print transfer information then is viewed through the printing blacket to identify portions of the underlying substrate which bear information indicating that the print should not appear on a corresponding portion of the coated substrate. After such portions are identified, the printing layer (11) is removed from the support layer (12) in those areas of the printing blanket which are adjacent to the identified portions of the substrate.

IPC: H04N21/4405
Filed: 1998-12-04
Abstract: Bulk operation logic circuitry (fig. 1) for use in carrying out bulk program, erase, verify and margining operations on nonvolatile memory cells of a PLD, FPGA, flash-based microcontroller, EEPROM, flash memory device or other integrated circuit containing such cells includes a flag register (31) for designating one or more selected blocks of cells to which the bulk operation will be limited. The bulk operation circuitry includes a controller (11), with a state machine (13) and associated control logic (17, 19), that distributes system clock signals and provides control signals to an instruction register (21), the flag register (31), an address register (33) and one or more data registers (35) to control loading of instructions and data into those registers through a serial input (SDI). The state machine is responsive to a mode signal (MODE) for switching it from a normal user state into a bulk operation state. The use of a flag register (31) allows simplification of the instruction set (Fig. 4) to register load instructions and basic bulk operation instructions (and a flow through operation using a serial output from the registers), while providing a wide variety of possible block selections for the different bulk operations.

Title: System for convective warming of a patient during cardiac surgery
Inventor: AUGUSTINE SCOTT D
IPC: A61F7/00
Filed: 1998-07-31
Abstract: A warming system is provided for convectively warming a patient during a progressive medical procedure, such as cardiac surgery. The system includes one or more inflatable thermal blankets that are adjustably configurable to cover one or both of a patient's legs. Each thermal blanked includes an inflatable covering formed from an upper sheet and a base sheet attached at a plurality of locations.  The base sheet includes a plurality of apertures that direct an inflating medium from the inflatable covering toward the patient. A portion of each thermal blanket is initially furled us-ing a retaining device that prevents an inflating medium from inflating the furled portion. The non-furled portion of each thermal blanket is allowed to inflate and cover a patient. Prior to inflation, the furled portion of each thermal blanket defines a thermal blanket edge which demarcates an access area for a surgical procedure. When the re-taining strip is removed, the furled portion is unfurled by action of the inflating medium and self erects into a continuation of the previously inflated non-furled portion of the thermal blanket to cover the surgical access site. A surgical drape may be placed over the tops of the thermal blankets in order to properly position each blanket on the patient, to maintain the temperature controlled medium proximate to the patient, and to perform the usual barrier functions of a drape. In the operation, a heater/blower that includes a compressor and a heater supplies heated air, under pressure, to an inlet opening in the one or more inflatable thermal blankets. The heated, pressurized air is distributed throughout each inflatable blanket, and flows to the patient through the apertures in the blanket's base sheet.

Title: Reconfiguration of a cellular telephone network
Inventor: BARK ANNA-SOFIE
IPC: H04W24/02
Filed: 1998-08-19
Abstract: A method is disclosed for performing a reconfiguration of a cellular telecommunications network, for example in the event that a base station becomes inoperative, or if it becomes necessary to increase traffic capacity by splitting a cell. Each base station controller, and an operator support system, each includes a database containing prestored sets of parameters or cell profiles. If one of these stored cell profiles is suitable for use in a reconfiguration, it can be selected at the operator support system, and then retrieved from the database in each affected base station controller. This avoids the need to carry out consistency checks on the cell profile, because it will have been checked before being stored. Moreover, only a simple command needs to be sent to the base station controller, and it is not necessary to transmit the complete file containing all of the cell parameters. Thus reconfigurations can be carried out more efficiently.
