Patent CA-2365747-A1 (CA)
Title: Deterministic refrigerator defrost method and apparatus
Inventor: QUEEN JERRY J II
IPC: F25D21/00
Filed: 2001-12-20
Abstract: A defrost control system for a self-defrosting refrigerator is configured to monitor a compressor load, determine whether at least a first defrost cycle is required based on the compressor load, execute at least one defrost cycle when required; and regulate the defrost cycle to conserve energy. A controller is operatively coupled to a compressor, a defrost heater, and a refrigeration compartment temperature sensor. The controller makes defrost decisions based on temperature conditions in the refrigeration compartment in light of other events, such as refrigerator door openings, completed defrost cycles, and power up events.  Defrost cycles are automatically adjusted as operating conditions change, thereby avoiding unnecessary energy consumption that would otherwise occur in a fixed defrost cycle.

Abstract: In modular design flow, logic designers are able to partition a top-level logic design for a PLD into modules and implement any module independently from other modules. Modules are mapped, placed, and routed using selected information derived at the time the top-level logic design is partitioned. Finally, the modules are integrated into the top-level logic design using a guided process. Specifically, the information generated during the partitioning of the top-level design and the implementation of each module i s used to guide the implementation of the associated logic in the top-level design. In this manner, the implementation of all modules can proceed in any  order or in parallel and the integration of the modules into the top-level design can be done quickly and in any order.

Title: Five-port topology for direct down-conversion
Inventor: BRANKOVIC VESELIN
IPC: H04B17/40
Filed: 2003-01-17
Abstract: The underlying invention generally relates to the field of five-port receivers, especially to a new topology for a five-port junction device (11) with three power sensors (PD1, PD2 and PD3) to be applied to the processing and direct down-conversion of broadband RF signals within an operation band-width between 1 and 7 GHz. Thereby, said receiver does not need any additional passive (resistive) network, which leads to a significant increase in the overall signal-to-noise (S/N) performance. Compared to receivers with a resistive five-port topology according to the state of the art, a non-optimized structure sensitivity enhancement (system gain) of 8-9 dB can be observed. Since a simpler technology is em-ployed, a significant decrease in microchip side (of more than 50 %) can be achieved.      The key issue of the proposed solution is to connect power detectors (PD1, PD2 and PD3) in a II-type network topology, and to attach resistive and/or reactive components - e.g. a combination of two or more parallel and/or series-connected resistors (R), capacitors (C) and/or inductors (L) or a transmission line (1a) of a specific length, which is usually placed outside of the microchip (10) - between two connection nodes (A and B). The actual matching of the power detectors (PD1, PD2 and PD3) does not play an important role due to the calibration procedure, Thus, the main issue is how to get the highest possible power with minimum losses to the detector sources (PD1, PD2 and PD3) while approving the same method of phase shifting as conventional solutions.
