Filed: 2008-01-08
Abstract: The invention provides an uncomplicated ball check valve whose components can be economically manufactured, assembled and connected and wherein, in accordance with one aspect of the invention, the ball check valve is configured for use as a pressure vessel. In one embodiment of the invention, the ball check valve comprises a housing defining one or more inlets, an outlet and a passageway therebetween. A ball support system is mounted within the housing, wherein one or more balls are supported by the ball support system. The ball support system is configured to allow a ball to close off and open a respective inlet. The housing generally comprises an inlet section which can have one or more inlets, wherein each inlet defines a ball seat sealingly engageable with a ball for sealing the inlet. The housing further comprises a centre section providing adequate space to allow movement of the ball and an outlet section comprising an outlet for transferring the fluid to a subsequent portion of a piping network. The ball support system is configured to guide the movement of each of the one or more balls, wherein the movement of each ball is guided from a first position wherein the ball is proximate to a ball seat located at an inlet and thereby sealing that inlet, to a second position wherein fluid flow through an inlet into the valve is enabled.

Abstract: The invention discloses a direct rotation-inducing generator, which comprises an iron core bracket, and a rotating shaft is arranged on the iron core bracket. A first rotary disc and a second rotary disc are respectively arranged on both ends of the rotating shaft. A first iron core is arranged on the iron core bracket and a first coil is arranged on the periphery of the iron core bracket. A first sealing plate is arranged on the first rotating disc, a first magnet is arranged on the first rotary disc or the first sealing plate, and the surface of the first magnet and the first sealing plate share a same surface. A fourth magnet is arranged on the second rotary disc, the first magnet and the fourth magnet correspond with the two ends of the first iron core, and the first magnet faces the fourth magnet by the opposite poles.  One end of the first iron core is provided with a liquid storage tank, which is filled with magnetic liquid, and the end filled with magnetic liquid in the first iron core contacts with the first sealing plate. The main magnetic flux of the direct rotation-inducing generator and the magnetic flux generated by induced current are both horizontal with the iron core within the iron core, which significantly reduce the resistance effect on the relative rotation of the iron core and the magnets, thus saving the energy for power generation.

Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.

Abstract: Techniques for performing open-loop rate control in a TDD communication system are described. The channel quality of a first link is estimated based on a transmission received via the first link. The channel quality of a second link is estimated based on the estimated channel quality of the first link and an asymmetric parameter. At least one rate for a data transmission via the second link is selected based on the estimated channel quality of the second link. The estimated channel quality for each link may be given by a set of SNR estimates for a set of transmission channels on that link.  The asymmetric parameter may be determined based on (1) the capabilities (e.g., transmit power, receiver noise figure, and number of antennas) of the transmitting and receiving stations or (2) received SNRs for the first and second links.

Title: Method and system for user equipment location determination on a wireless transmission system
Inventor: TEE LAI KING
IPC: H04W4/02
Filed: 2010-02-05
Abstract: Neighbor cell hearability can be improved by includ-ing an additional reference signal that can be detected at a low sensi-tivity and a low signal-to-noise ratio, by introducing non-unity fre-quency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new ref-erence signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP    EU--TRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regard-less of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.
