Abstract: In an echo cancelling method of a p-order fast projection algorithm which subtracts an estimated echo signal ~(k) from a microphone output signal u(k) to obtain an error signal e(k), adaptively calculates a pre-filter coefficient .beta.(k) from the auto-correlation of a received speech signal x(k) and the error signal, generating an intermediate variable z(k) updated by a coefficient s(k) obtained by smoothing the pre-filter coefficient, convolutes the received speech signal x(k) and the intermediate variable z(k), calculates the inner product of the auto-correlation of the received speech signal and the smoothed pre-filter coefficient s(k) and adding the inner product and the convoluted output to obtain the estimated echo signal, the magnitudes of the received speech signal x(k) and the error signal e(k) are compared and when the result of comparison satisfies a predetermined condition, a reset signal is generated to set the pre-filter coefficient .beta.(k) to zero for at least a period of time p, thereby preventing the accuracy of estimated echo characteristics from lowering during double-talk or send single-talk.

Granted: 2002-09-17
Abstract: In a magneto-optic method of measuring an a.c. current in a conductor, the plane of rotation of linearly polarized light is rotated through a measuring angle in a Faraday element surrounding the conductor, the angle being a measure of the current strength. This light is divided into two linearly polarized light signals, with polarization planes directed at right angles to each other, which are converted by opto-electro converters into corresponding electrical signals.      The two signals are used to form a functional value that represents the temperature. This value is used, together with the first signal, to determine a temperature-compensated measuring signal for the a.c. current.

Title: Time diversity communication system
Inventor: ITO SHOGO
IPC: H04B7/02
Filed: 1995-03-10
Granted: 2005-08-02
Abstract: The probability of receiving signals correctly in a selective radio paging receiver is improved by a time diversity reception scheme. Time diversity reception is therefore applied to both the address signal and the message signal that make up a paging signal. In other words, time diversity reception is performed for each error-corrected or error-detected code word, without distinguishing between the address signal and the message signal, said code words being the units which make up these signals. For example, a received signal comprising correctly decoded code words can be obtained by selecting, from among code words with the same content that have been received over a plurality of times, those code words that are judged to have been correctly decoded in accordance with error detecting logic. Alternatively, by selecting, from among code words that are judged to have been correctly decoded in accordance with error correcting logic, those with the smallest number of error-corrected bits, code words with the least likelihood of miscorrection can be selected from among corrected code words with the same content that have been received over a plurality of times. The probability of correct reception by a selective radio paging receiver is improved by these means. Moreover, when a code word has been correctly decoded, by prohibiting reception during the time intervals when code words with the same content and that are subsequently transmitted would be received, part of the selective radio paging receiver can be stopped from working, as a result of which, battery consumption can be decreased.

Filed: 1996-01-11
Granted: 2007-05-08
Abstract: In mobile radio systems, it may be necessary to support multiple radio interfaces (1, 2) within a single mobile radio network. To support these multiple radio interfaces, it may be necessary to support even multiple signalling protocols within a single interface (A--interface) between a base station controller (BSC) and a mobile switch (10), when base stations (BTS1, BTS2) supporting different radio interfaces are connected via a common base station controller (BSC) to the mobile switch (10). The mobile switch (10) and the base station controller (BSC) must be capable of recognizing to which signalling protocol a message transfer in the single interface belongs to. According to the present invention the messages transferred in the single interface (A-interface) are provided with a discrimination parameter which can be used to discriminate between the messages belonging to different radio interfaces (1, 2) and signalling protocols.

Abstract: An electronically controlled wastegate valve is adjusted so that the pressure drop across a throttle in the engine approaches an adaptively generated, desired throttle pressure reserve value. The desired throttle pressure reserve value is based at least in part on a history of the engine load. In the preferred embodiment, the engine speed is used as a surrogate for engine load to determine the desired throttle pressure reserve value. The desired throttle pressure reserve value is preferably pushed downward over time by use of a constant negative gain term in the electronic controller. In this manner, the wastegate control provides sufficient throttle pressure reserve for satisfactory load acceptance when engine load is fluctuating, yet minimizes throttle pressure reserve to improve engine fuel consumption when the engine load is relatively steady.

Abstract: A sticker placing mechanism for use with known lumber stackers and perpendicularly associated sticker distribution provides sticker pans carried by arms of a lumber stacking fork to move downwardly to pick up plural stickers from the sticker conveyor and move the stickers upwardly beneath an accumulated layer of lumber. The layer of lumber and perpendicularly orientated stickers is moved upwardly and forwardly by the stacking fork on an adjacent stacked lumber package. The stacking fork and associated sticker pans then retract into the stacker while stripping mechanism prevents rearward motion of the stickers and lumber layer to leave the stickers and lumber layer as the top course of the stacked lumber package. In a first species, the sticker pans are immovably carried by the stacking fork arms and moved downwardly by those arms. In a second species, the sticker pans are pivotally mounted on the stacking fork arms and mechanically pivoted for sticker pick up. The sticker placing mechanism is adaptable to retrofitting on existing lumber stackers.
