Patent CA-2842555-A1 (CA)
Inventor: GROSS WARREN J
IPC: H04L45/74
Filed: 2014-02-07
Abstract: Internet routers are a key component in today's Internet. Each router forwards received packets toward their final destinations based upon a Longest Prefix Matching (LPM) algorithm select an entry from a routing table that determines the closest location to the final packet destination among several candidates. Prior art solutions to LPM lookup offer different tradeoffs and that it would be beneficial for a design methodology that provides for low power large scale IP lookup engines addressing the limitations within the prior art.  According to embodiments of the invention a low-power large-scale IP lookup engine may be implemented exploiting clustered neural networks (CNNs). In addition to reduced power consumption embodiments of the invention provide reduced transistor count providing for reduced semiconductor die footprints and hence reduced die cost.

Title: Voltage converter systems
Inventor: ISURIN ALEXANDER
IPC: H02M1/44
Filed: 2014-03-14
Abstract: A voltage converter system includes a first DC-AC voltage converter that converts a first DC voltage signal to a first AC voltage signal. A DC link converts the first AC voltage signal to a second DC voltage signal. A second DC-AC voltage converter converts the second DC voltage signal to a second AC voltage signal. In another configuration a DC-AC voltage converter converts a DC voltage signal to a first AC voltage signal. An AC-AC voltage converter converts the first AC voltage signal to a second, lower-frequency AC voltage signal. In yet another configuration a first voltage converter portion converts a DC voltage signal to pulses of DC  voltage. A second voltage converter portion converts the pulses of DC voltage to a relatively low-frequency AC voltage signal. The voltage converter system is selectably configurable as a DC-AC voltage converter or an AC-DC voltage converter.

Title: Electric fuel pump tester and method
Inventor: MCGAUGHEY ROBERT J
IPC: G01R31/72
Filed: 2012-08-16
Abstract: The system and method for determining the operational condition of an electric fuel pump (16). The test apparatus (22) is configured to perform first, second and third tests. During the first test, a low voltage, low current signal is applied to produce an inductive reflectance from the pump armature winding. During the second test, continuity is assessed in the coil winding circuit. During the third test, a higher power, short duration pulse is applied to create rotational movement of the pump armature for the purpose of detecting mechanical and/or electrical issues not otherwise discerned from the prior tests. An optional fourth test may be conducted in which the pump (16) is run for a short period of time at standard operating power to generate a current waveform. Collected test data is compared to stored reference data sets using a processor contained within the test apparatus (22). If collected test data corresponds within an acceptable threshold range to the reference data, a PASS signal is generated.
Patent CA-2851858-A1 (CA)
Inventor: WEIGOLD THEODORE
IPC: F22B1/02
Filed: 2012-10-15
Abstract: Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber.  The liquid is introduced by controlled injectors operating at a required rate.  Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

Title: A method and a sensor for determining a direction-of-arrival of impingent radiation
Inventor: TUXEN FREDRIK
IPC: G01S13/44
Filed: 2012-12-13
Abstract: A sensor for determining a direction-of-arrival of radiation impingent on the sensor which has antennas positioned in a particular set-up different from a rectangle, so that information may be derived between two pairs of the antennas, positioned in corners of a rectangular grid and additional information may be derived from an additional antenna, combined with one of the "grid" antennas forming a third pair of antennas. The additional antenna is positioned away from the corners and other pre-defined lines of the rectangle/grid. In this manner, such as from phase differences between the pairs of antennas, more information may be derived compared to antennas positioned merely at the corners of a rectangle to remove ambiguous angles of direction-of-arrival without compromizing accuracy of an angular determination.
