Patent CA-2322283-C (CA)
Title: Optical switch for headset
Inventor: MAGNASCO JOHN H
IPC: H04M1/05
Filed: 1999-02-24
Granted: 2005-08-02
Abstract: An optical switch for controlling an operative condition of a (telephone) headset.      The headset includes a microphone boom that is rotatable with respect to a housing for the headset. A rotator element is coupled to the microphone boom such that the rotator element rotates with respect the housing along with the microphone boom. Selected portions of a surface of the rotator element are conditioned to be more reflective than the remaining portions. Alternately, portions of the rotator element are opaque. A pair of optical transceivers are in fixed positions relative to the housing. When the microphone boom is positioned approximately straight upward with respect to a user's head, reflective portions of the rotator element are within a field of view of each optical transceiver of the pair. In this position, the headset is in an "off' or "standby" mode. When the microphone boom is positioned approximately level with the ground, a reflective portion of the rotator element is not within the field of view of the first optical transceiver, while a reflective portion is within the field of view of the second optical transceiver.      In this position, the headset is in a "mute" mode. When the microphone boom is pointing downward, a reflective portion is not in the field of view of either of the two optical transceivers. In this position, the headset is in a "talk" mode. The optical transceivers are less susceptible to wear, contamination and misalignment, and occupy less space than prior mechanical switch devices.

Abstract: A SAW filter comprising a piezoelectric substrate and at least two filter tracks formed on the substrate, each having at least two IDT electrodes for input and output. The two filter tracks have substantially the same phase within a pass band, while it is substantially inverse-phased outside the pass band. For realizing the above-described conditions, input IDT electrode of one filter track is connected in parallel with input IDT electrode of the other filter track, while output IDT electrode of one filter track is connected in parallel with output IDT electrode of the other filter track. Furthermore, frequency values of said two filter tracks substantially coincide at a point 3dB lower from the peak transfer function value. Thus the above-configured SAW filter of the present invention is smaller in the overall size and offers a broad pass band and a steep attenuation characteristic.

Abstract: In a method for determining the logic state of memory cells in a passive matrix-addressable data storage device with word and bit lines, components o f current response are detected and correlated with a probing voltage, and a time-dependent potential is applied on selected word and bit lines or groups thereof, said potentials being mutually coordinated in magnitude and time su ch that the resulting voltages across all or some of the non-addressed cells at the crossing points between inactive word lines and active bit lines are brought to contain only negligible voltage components that are temporally correlated with the probing voltage. A first apparatus according to the invention for performing the method provides sequential readout of all memor y cells on an active word line (AWL) by means of detection circuits (3; 4). An active word line (AWL) is selected by a multiplexer (7), while inactive word lines (IWL) are clamped to ground during readout. A second apparatus for performing the method is rather similar, but has only a single detection circuit (3, 4). An active word line (AWL) is selected by multiplexer (7) and a bit line (ABL) is selected by a multiplexer (9) provided between one end of the bit lines (BL) and the input of the detection circuit (3, 4), while inactive word and bit lines(IWL; IBL) are clamped to ground during readout.< /SDOAB>

Abstract: A turbocharger (32) creates intake manifold boost for a diesel engine (10). At times, exhaust valve opening is increasingly retarded in relation to the engine operating cycle to cause the turbocharger (32) to increase boost, engine fueling is also increased in relation to the increased boost, and in response to any incipient surging of the compressor (38) resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold (14) to counter the incipient surging and thereby avoid any significant turbocharger (38) surge.
