A rotary position sensor is disclosed having a magnetic element having a cavity therein. A flux concentrator is arranged to substantially surround the magnetic element, and a magnetic field sensor located within the cavity. The magnetic element may have rectilinear portions.

Rotary position sensor

Systems and methods are disclosed for timer architectures. For example, in accordance with an embodiment of the present invention, a timer system includes a prescaler and one or more timer cells each having a multiplexer and a counter.

Timer systems and methods

A throttle control device for transmitting signals to an electronic fuel control system for a vehicle engine is provided that includes an electromagnetic field generator and first and second electromagnetic field sensors positioned proximal to electromagnetic field. The electromagnetic field and the first and second sensors being manipulatable relative to each other, and the sensors being responsive to the relative manipulation. The sensors configured to independently transmit signals representative of said relative manipulation.

Throttle control method and apparatus

A method and apparatus is provided to power-up a device having both digital and analog circuitry. The analog circuitry requires a stabilization period before proper operation. During power-up, the digital circuitry is held in reset by a power-on reset circuit. The power-on reset circuit releases the reset after the expiration of a power-on reset period. During the period of time after expiration of the power-on reset period and before the analog circuitry reaches equilibrium, the digital circuitry operates in a mode that does not require input signals from the analog circuitry. After the analog circuitry has reached equilibrium, the digital circuitry begins normal operation during which inputs signals from the analog circuitry may be processed by the digital circuitry.

Powering-up a device having digital and analog circuitry

A programmable logic device configurable to implement a finite state machine includes a hardwired microsequencer for executing microinstructions to sequence the finite state machine. The hardwired microsequencer includes a sequence memory for storing the microinstructions and a program counter.

Programmable logic device with hardwired microsequencer

Systems and methods are disclosed to provide threshold detection and successive approximation analog-to-digital conversion. For example, in accordance with an embodiment of the present invention, a circuit is disclosed that provides successive approximation analog-to-digital conversion and high-speed threshold detection operations by utilizing common hardware resources.
