Abstract: A compact child's travel pillow that is easily opened and unfolded into a shopping cart seat cover that provides child safety, comfort, and protection from the contaminated surfaces of shopping cart seats, then easily refolds into a compact firm travel pillow.

Abstract: A valve operating mechanism is described for an internal combustion engine in which at least one valve (14) of an engine cylinder is operated by two cams (10,12). The cams (10,12) have respective cam followers (38,36) which are resiliently biased to remain in contact with the cams (10,12) at all times and which act on the valve (14) by way of a summation linkage (20,24) in such a manner that the displacement of the valve (14) at any instant is determined by a combination of the displacements of the two cam followers (38,36). In the invention, movement of each of the two cam followers (38,36) is transmitted to the summation linkage (20,24) by way of a respective one of two pushrods (28,30).

Abstract: A semiconductor device comprises a DSP (Digital Signal Processor), a CPU for controlling the DSP and an interface circuit. The interface circuit comprises an input circuit, a gain-adjusting circuit and an output circuit. The input circuit inputs a digital signal and supplies the signal to the DSP synchronously with a first clock signal. The gain-adjusting circuit is capable of adjusting the gain of the digital signal supplied to the input circuit. The output circuit adds a digital signal received from the DSP to the digital signal with the gain thereof adjusted and outputs a signal obtained as a result of the addition synchronously with the first clock signal. A signal path extended from the input circuit through the gain-adjusting circuit to the output circuit forms hardware. A digital signal to be transmitted propagates through the hardware to be subjected to the so-called side-tone processing.

Abstract: A novel arrangement of a capacitive oil level and temperature sensor specifically provided to be mounted to a drive axle housing of a motor vehicle, is disclosed. The sensor comprises an L-shaped hollow body allowing for a simple fit in current production axles. The L-shaped hollow housing of the oil level sensor comprises a pair of mutually perpendicular legs. A substantially vertically oriented first leg includes an oil level detecting capacitor and adapted to be at least partially immersed in an oil reservoir of the axle housing. An oil temperature detecting thermistor is also disposed within the sensor housing. A second leg is substantially horizontally extending from the axle housing and contains an electronic sensor circuitry electrically coupled to the oil level detecting capacitor and to the thermistor, and is adapted to generate oil level and temperature output signals.
