Abstract: A method and apparatus are disclosed for closed-loop phase modulation, intensity demodulation, control, and estimation of the non-reciprocal phase shift induced in a rotation sensing interferometer with a reciprocal phase modulator (18) near one end of a closed light path. A bias modulation signal and a feedback modulation signal are generated, the two signals are summed to form a summed signal which is applied to the phase modulator (18), the intensity interference signal is demodulated to generate a Sagnac phase estimate signal and bias modulation gain error estimate signal, the phase modulator (18) is corrected for gain variation, and the Sagnac phase estimate signal is extracted to provide an estimate of inertial rotation of the closed light path. The waveform of the bias modulation signal consists of a sequence of periodic step transitions between two or more signal levels, each with a duration of preferably 2T o , where T o  is the time required for light to travel once around the closed optical path of the interferometer. The difference between any two adjacent levels corresponds to a phase difference of approximately π /2 radians. Transitions from one level to another introduce instantaneous non-reciprocal phase shifts at the photodetector of the interferometer of -3π/2, -π/2, +π/2, or +3π/2 radians. The step transition frequency of the bias modulation signal is chosen so as not to fall on even harmonics of the proper frequency f p  = 1/2T o . The feedback modulation signal can consist of any periodic amplitude modulated square wave with spectral frequency components at harmonics of the bias modulation step transition frequency. The spectral power of the feedback modulation signal must be distributed across frequencies other than even harmonics of the proper frequency f p .

Abstract: In a system (60) for controlling the gear ratio of a multi-step geared or continuously variable automatic transmission of a vehicle (10) based on determined parameters indicative of operating conditions of the vehicle including a driving resistance, the driving resistance is calculated in an equation in which motive force - driving resistance = vehicle mass x acceleration using the law of motion. In the first embodiment, the calculation is carried out, without using a torque sensor, by applying an adjustment for torque consumption by a device such as an air conditioner and the torque loss caused by braking. In the second and third embodiments, the driving resistance is calculated using a torque sensor (80). Thus, with the arrangement, the driving resistance can be accurately determined by applying appropriate adjustment, and the gear ratio to be shifted to is properly determined in any travelling condition including hill climbing.

Abstract: Two edge detectors (12, 13) at the input (10.1) and at the output (10.2) of a delay line (10) of the edge detector arrangement (11) generate detection signals with identical shape at the detected signal edges of a signal passing through the delay line. The delay time of the delay line is selected in such a manner that the two detection signals partially overlap in time. A subtracting arrangement (16) generates from the two detection signals a difference signal which contains in the overlap region a zero crossing which can be detected by a zero crossing detector (17). At the time of this zero crossing, the zero crossing detector generates the switching edge of an edge detection signal which, for example, controls a signal switch (9). <IMAGE>

Abstract: In a semiconductor device, in addition to a first emitter layer, a second emitter layer is formed on the surface side of a p-type base in spaced-apart relation with the first emitter layer. The first emitter layer is the source region of a first MOSFET, while the second emitter layer is the source region of a second MOSFET. Through signals imparted to first and second gate electrodes, the device, when turned on, operates with a low on-voltage in a thyristor state and, when turned off, undergoes a turn-off in a short time by changing to a transistor state. The main current in the transistor state flows by being offset toward the first emitter layer side with respect to a main-current path on the lower side of the second emitter layer in the thyristor state. Since the current paths in each mode are separated, it is possible to reduce the resistance in the current path in the transistor state without increasing the on-voltage, thereby making it possible to obtain a large latch-up withstanding capacity.

Abstract: In a method for determining the position of a motor vehicle part, driven in two directions by an electric motor, with the aid of a counter, when the part moves in its two directions counting pulses of a position sensor (transmitter, transducer) are input into the counter in order to reduce or increase the counter reading in accordance with the prescribed movement. After disconnection of the drive motor, the pulses delivered by the position sensor are analysed as to their temporal distance from the instant of disconnection and are assigned to a further movement of the counter if the temporal distance of the pulses does not exceed a prescribed measure. Upon polarity reversal of the drive motor, the direction of counting is not assigned to the new direction of movement until the distance of the pulses has decreased again after the polarity reversal. <IMAGE>

Abstract: A voice encoder which pauses outputting codewords in accordance with the absence of voice activity. An input aural signal is divided into frames and inputted to the voice encoder. The voice encoder has a voice activity detection circuit for determining at each frame whether voice activity is absent or present, a voice encoding circuit, a background noise update judging circuit for detecting a change in the characteristics of the input aural signal, and a control circuit. If the absence of voice activity is detected, the control circuit causes the frame at that time to be encoded as a background noise frame, and then pauses the operation of the voice encoding circuit. If the presence of voice activity is detected, the operation of the voice encoding circuit is resumed. Furthermore, if the voice encoding circuit is not in operation when a change in the characteristics of the input aural signal is detected, the control circuit causes the voice encoding circuit to encode the frame at that time as a background noise frame and then again stop the operation of the voice encoding circuit. 
A method of voice encoding is also disclosed.
