Abstract: A limiter is connected with the output of a PLL to limit the amplitude of the output from the PLL. The output from limiter is supplied to a voltage-controlled oscillator (VCXO). The limiter determines the difference between the input signal and the output signal. If the difference exceeds a predetermined value, the change in the output from the limiter is limited to the predetermined value. If the difference does not exceed the predetermined value, the change in the output is considered to be a difference value.

The VCO includes a plurality of basic cells having differential input/output, and a center frequency adjustment circuit. The plurality of basic cells are serially connected in a ring. Each basic cell includes a circuit constituted by two delay circuits and an adder circuit, the delay times of the two delay circuits being each independently determined by the center frequency adjustment circuit. The output amplitude of each of the basic cells is controlled to a fixed value. In the adder circuit, the output of one of the delay circuits is multiplied by an addition proportion coefficient, following which the outputs of both delay circuits are added. In this way, the delay time for each basic cell can be set over a broad range.

Abstract: In an immobilizer controller, a key-side identifying information stored in a key is collated (compared) with an immobilizer-side identifying information stored in the immobilizer controller. In a shift controller, the key-side identifying information is collated with a shift-lock-side identifying information stored in the shift controller. If the identifying informations do not coincide with each other in at least one of the immobilizer controller and the shift controller, neither a fuel-injection-control permitting command nor a shift-lock-cancellation permitting command is output. An engine is maintained in its inoperative state, and a transmission is maintained in a state where rotation of a driving-torque transmitting shaft is prevented. If the identifying informations coincide with each other in the immobilizer controller, it is possible to reinforce security in comparison with the case where the fuel-injection-control permitting command and the shift-lock-cancellation permitting command are output.

Abstract: Movement of a mouse or joy stick is detected by optically tracking with a navigation sensor the change in position of the micro-texture on a ball instead of using the ball to actuate shaft encoders. The interior of the mouse or joy stick is an optically controlled environment where the external ambient illumination is excluded, the angle, and intensity of a desired illumination is established once, and the only surface to be imaged and tracked is a part of the ball. As the ball rotates a portion of the old image passes from view as a new portion emerges. Consecutive images are represented internally within the optical tracking mechanism as arrays of pixels, and the tracking mechanism tolerates the disappearance of some pixels along one side of the field of view whilst other pixel appear from the other side of the field of view. Pattern matching of unchanged pixels determines movement.

Abstract: Existing media signals are processed to create new media content by defining content representations for the existing media and establishing functional dependencies between the representations. The content representations comprise different data types which determine the kinds of operations that can be performed and dependencies that can be established. Among the types of transformation that can be achieved are synchronization, sound substitution, and the creation of parametric special effects. The content representations and their functional dependencies are combined to construct a functional dependency network which causes the desired transformations to occur on input media signals. The inputs to the functional dependency network are parametrically specified by media data types to construct a template that can be used to create adaptive media productions.

Thereby, the distribution of dense and less-dense parts can be generated in the elastic body without forming wrinkles therein and gaps between the elastic body and the inner surfaces of the ink tank. Consequently, ink supply capability can be raised and printing quality can be improved.

Abstract: A print head includes a driving circuit having a cascaded series of driver integrated circuits mounted on a printed wiring board. Differential clock signals are supplied to the driver integrated circuits to synchronize the transfer of print data through the cascaded series. Even-numbered driver integrated circuits and odd-numbered driver integrated circuits are connected differently to the clock signal lines, but the even-numbered (or odd-numbered) driver integrated circuits generate an inverted internal clock signal, thereby compensating for the difference. This enables the clock signal lines to be mutually adjacent and to have a weaving layout that yields improved noise immunity.

If the remaining number is more than zero, the system controller keeps the lock lever at the lock position.

Abstract: An improved technique for updating a memory in digital pixel sensors in which a memory update may be directed to only some of the locations or cells in the memory is disclosed. According to one embodiment, a multiplex scheme is employed, in which a threshold memory identifies the locations within a row of memory that are to be updated. Data are first read out of a row of memory to be updated. The data are copied to a first buffer or other short term storage area within the digital pixel sensor. New data from the sensor portion of the digital pixel sensor to be written to the memory are stored in a second buffer. The contents of the threshold memory are then applied to a select input of a multiplexer, where the contents of the first and second buffers comprise first and second data inputs to the multiplexer. Thus, the output of the multiplexer comprises an updated row of memory in which only those locations that are to be updated have been changed.
