Abstract: A message generation and automatic dialing system is used in conjunction with a telephone for a customer to receive product information and to place an order for the product or service. The product information such as product list and prices are prerecorded in a ROM and broadcast from a speaker, which is acoustically coupled to the telephone. The speaker then automatically generates dialing tones to connect the telephone to the customer service of the product company for the user to place an order of any product.

Abstract: An optical sensor switch system is used to effect a selection function of a scanner. The depressed switch for a selected function changes the light intensity incident on the pixels of a light sensitive panel in two steps. This change in light intensity activates the operation of the particular function. The change in light intensity is effected by shuttering the light from a source to the pixels. The pixels of the panel are divided into different sections, each designated to a particular function for the scanner.

Abstract: A heat conducting metal is placed under a semiconductor chip and wraps around a substrate of the semiconductor device package to serve as the heat sink for the chip. The metal can wrap around a through-hole in the middle of the substrate, or wrap around the edge of the substrate. A metal plate can be placed between the chip and the heat conducting metal to hold the semiconductor chip.

Abstract: During transient operation of a voltage regulator, the gate of p-channel MOS pass transistor may be pulled down during the transient period to cause excessive surge current. The surge current is limited by using the pass transistor as a current mirror during the transient period. After the transient period, the pass transistor resumes its role as an element together with a differential amplifier and a reference voltage in a feedback loop to regulate the output voltage.

Abstract: A control circuit is used to increase the dc current of a low noise amplifier for a mobile wireless communication system in the presence of jamming signal to preserve high dynamic range and low intermodulation distortion. The control circuit compares the peak jamming signal with the average input signal. The average signal is obtained by filtering the input signal with a low-pass filter. The difference signal between the input signal with jamming signal and the average input is detected by a peak detector. The detected signal is then again compared with the average input signal to obtain a dc control signal to control the power consumption of a LNA.

Abstract: A gravity motor which is formed of at least one motor unit which has at least one motor member fixed to an output shaft. The output shaft is rotationally mounted on a housing. The housing includes a guide surface. The motor member is low frictionally longitudinally movable relative to an output shaft. Each end of the motor member includes a weighted follower which is low frictionally movable relative to a guide surface. The rotation of the motor unit will cause one weighted follower to be moved toward the output shaft by the guide surface with the opposite weighted follower of the motor member being moved away from the output shaft. The result is gravity produces an overall clockwise torque on the motor member which causes rotation of the output shaft.

Abstract: An interior rearview mirror for vehicles has a housing having an interior. A mirror support has a first end and a second end, wherein the housing is connected to the first end of the mirror support and wherein the first end projects into the interior of the housing. A mirror pane is mounted in an opening of the housing. A switching member is mounted in the interior of the housing and is pivotable on the first end of the mirror support. An adjusting lever is mounted in the housing and projects from the housing. At least one spring is configured to act on the adjusting lever. The adjusting lever is movable against a force of the at least one spring and acts on the switching member for pivoting the mirror pane from a normal viewing position into a non-glare position. The switching member receives the force of the at least one spring exerted onto the adjusting lever and thus prevents deformation of the housing.

Abstract: The frequency of oscillation of two cross-coupled CMOS inverters with a parallel LC tank connected between the two drains can be varied by a control voltage which varies the capacitance value of the tank circuit. The gate-to-source capacitance is used as the variable capacitance. The gate-to-source capacitance is varied by changing the dc gate voltage, which can be effected by either changing the dc current through the inverters or by varying the dc voltage across the inverters. The control voltage may also be made to vary with temperature such that the free running frequency of the oscillator is held constant with varying temperature.

Abstract: An array antenna is steered by moving two sets of optical fibers of different optical lengths between a number of light signal sources and an array antenna. By changing the lengths of the optical paths of the different light signal sources, the wave front can be steered. The light signal traverses five sections of optical delay lines with at least two selectable optical lengths. One set of selectable optical lengths provides coarse adjustment of steering, and a second set of selectable optical lengths provides fine adjustment of steering. The coarse adjustment is implemented by using a larger increment of selectable optical lengths between adjacent optical lengths than the increment for the fine adjustment. The antenna can serve both for a transmitter or a receiver.
