Abstract:
Various systems and methods for automatic data rate detection are provided. In one embodiment, a system is provided that includes a clock and data recovery circuit embodied in a first integrated circuit, the clock and data recovery circuit being configured to re-clock a data stream. The system also includes an automatic rate detection system embodied in a second integrated circuit, where the first integrated circuit is in data communication with the second integrated circuit. Also, the automatic rate detection system is configured to determine a data rate of the data stream upon identifying a transition in the data rate of the data stream based upon the state of the at least one status flag received from the clock and data recovery circuit.

International Rectifier Corporation - El Segundo CA
International Classification:
H02J 7/00
US Classification:
361 18, 307150
Abstract:
According to one embodiment, a smart photovoltaic (PV) panel comprises a plurality of PV cell groups each including at least one PV cell. The smart PV panel also includes at least one serial boost combiner circuit (SBCC) configured to receive an output from the plurality of PV cell groups as inputs. Each SBCC comprises several boost blocks connected in parallel, each of the boost blocks including a switching device and a respective boost block output directly connected to an output node of the SBCC. In addition a corresponding power terminal of each of the switching devices is directly connected to a common ground node of the SBCC. In one embodiment, the smart PV panel also includes a power inverter coupled to the one or more SBCCs and a communication unit interfaced with a local controller.

International Classification:
H04B 10/08
US Classification:
398027000
Abstract:
A method and system for a bit error rate (BER) contour-based optimum decision threshold and sampling phase selection in optical communication systems is disclosed. According to one aspect of the invention, for a selected sampling phase and a decision threshold, high BER values are measured. Low BER values are approximated from the high BER values using error functions. The procedures are repeated for all selected sampling phases and decision thresholds and corresponding BER values are calculated. The sampling phases and decision thresholds for each specific BER value are plotted to create the BER contour diagrams. The optimum decision threshold for a sampling phase is calculated by equating the BER due to marks (āsā) and the BER due to spaces (āsā). In one aspect of the invention, a BER test module resides in the receiver. The BER test module calculates the BERs and the optimum decision threshold and sampling phase.

Assignee:
INTERNATIONAL RECTIFIER CORPORATION - El Segundo CA
International Classification:
H02J 7/00
US Classification:
320134
Abstract:
According to one embodiment, a system for actively managing energy banks during an energy transfer process comprises a plurality of energy banks configured for use as a group of energy banks and characterized by a desired state-of-charge (SOC), and a power management system coupled across each of the energy banks. The power management system is configured to selectively drive at least one of the energy banks to a modified SOC different from the desired SOC without interrupting the energy transfer process. In one embodiment, the power management system is further configured to return the energy bank or banks driven to the modified SOC to the desired SOC of the group of energy banks.
Database Game Playing System Based On Pregenerated Data
A database system is disclosed for accessing databases, updating hands information associated with users. The database system can include a server. The server can retrieve and store data in the database. The server can retrieve a first request from a first computer over a network, the first request including a first set of authentication data. The server can identify the user and retrieve a first set of hands information data associated with the user from the database. The server can generate a first set of game data and transmit the game data to the first computer. It can then receive a first set of hands data from the first computer. It can compute a first game result based on the first set of hands data, the first set of game data and a first set of game rules.
Photodetection Sensor For Monitoring And Fault Detection
A battery monitoring module may be arranged in such a way as to receive a sensor signal from a light sensor configured to detect light within a battery module.
