An integrated hybrid energy generating system capable of converting wind and solar energy for use with an electrical generator. During the daytime, the system concurrently derives energy from both wind and solar energy sources. During the nighttime, it continuously harvests wind energy regardless of the weather condition.
摘要:
In a cellular communication system where two mobile stations are located within or near to a cell associated with a base station, one or more relay stations with good radio link quality relative to the two mobiles may be used to build a local forwarding communication link between the mobile stations using the one or more relay stations which avoids downlink/uplink transmission with the base station. The relay station(s) is(are) selected based on an association between two mobile stations and the relay station(s).

A system for environmental control includes a hybrid wind and solar energy collection subsystem; a temperature control subsystem having a thermo-mechanical engine; an electrical generating subsystem; a sensor for detecting an environmental condition; and a controller for receiving information representing an environmental condition from the sensor. The controller is programmed to detect a change in an environmental condition, and in response to the change, to selectively connect the hybrid wind and solar energy collection subsystem to one of the temperature control subsystem and the electrical generating subsystem and to selectively disconnect the hybrid wind and solar energy collection subsystem from the other of the temperature control subsystem and the electrical generating subsystem.

摘要:
Method and apparatus for generating a set of generator polynomials for use as a tail biting convolutional code to operate on data transmitted over a channel comprises: (0) specifying a constraint and a low code rate for a tail biting convolutional code, where the low rate code is lower than 1/n (n being an integer greater than 4); (1) selecting valid combinations of generator polynomials to include in a pool of potential codes, each valid combination being a potential code of the low rate code; (2) determining first lines of a weight spectrum for each potential code in the pool and including potential codes of the pool having best first lines in a candidate set; (3) determining best codes of the candidate set based on the first L number of lines in the weight spectrum; (4) selecting an optimum code(s) from the best codes; and (5) configuring a circuit(s) of a data transceiver to implement the optimum code(s).

An integrated solar and wind hybrid energy generating system is capable of converting a solar collector to a wind deflector to increase wind catching area for the wind turbine during the nighttime and on overcast days and exchangeable between modes of Stirling cycle and reversed Stirling cycle for electricity generation and environmental control. During the sunny days, the system concurrently derives energy from both wind and solar energy sources.
