Multiple scanning modes are provided for an array of electromagnetic radiation sensors. In the preferred implementation both selectable subarrays and the overall array can be read out and reset in any desired order, including interrupting a full array scan for a subarray scan and then resuming the full array scan.

A device is disclosed that enables a user to perform a simulation of walking and running. The device comprises a locomotion platform which is has a concave upward facing surface. The platform and or the user's footwear incorporate a means to reduce friction to allow their feet to move freely.

An image sensing system includes an image sensor and a black clamping circuit which reside on the same substrate. Particular embodiments use common components for both imaging and black clamping, and digital control of an analog black clamp function.

A braking system allows for smooth and accurate stopping of a camera dolly operating on tracks. A pair of caliper brake modules attached to the dolly frame are sized so that they fit over and at least partially surrounds the track. When the caliper brakes are activated, brake pads are moved towards the surrounded track squeezing it and providing a significant braking force. This permits the dolly to be smoothly brought to a stop with no possibility of the dolly wheel locking and skidding. The br...

A method and circuit for sensing multi states of a NAND memory cell by applying reverse bias voltage at a constant gate voltage, preferably zero volts, generating a memory cell current in response to the applied reverse P well bias, and sensing the memory cell state.
