Method and apparatus for dynamic space-time imaging system

A method for creating a 3 D map of the surface contours of an object includes projecting a variety of patterns onto the object, and imaging the patterns as they fall on the object to encode the topographic features of the object. In one embodiment a three dimensional image is taken in a single flash to avoid blurring due to motion of the object. Thereafter a secondary pattern is projected to detect changes in the initial image. The images are processed in a computer program in a manner such that a complete 3D map of the surface of the object is obtained in digital form. Reiteration of the method can detect motional variation such as a breathing human, flexure of a complex mechanical structure, or a stress-strain testing of an airplane, vehicle, beam, bridge, or other structure.

Flash memory controller controlling various flash memory cells

An electronic data flash card is accessible by a host system, and includes a flash memory controller and at least one flash memory device coupled to the flash controller. The boot code and control code for the flash memory system (flash card) are stored in the flash memory device during a programming procedure. The flash controller transfers the boot code and control code to a volatile main memory (e.g., random access memory or RAM) at start up or reset making a RAM-based memory system. Boot code and control code are selectively overwritten during a code updating operation. A single flash controller thus supports multiple brands and types of flash memory to eliminate stocking issues.

Control of a flash unit in a digital camera

The invention is based on a method for controlling a flashlight in connection with a digital image sensor without a mechanical shutter, wherein the exposure of the image sensor is performed in sub-areas, such as pixel rows or columns, or in another order, by using a rolling electronic shutter or the like. Thus, the exposure of said sub-areas of the image sensor takes place at least partly at different times. According to the invention, during the time of exposure of one image, i.e. substantially all the sub-areas of the image sensor, several discrete, successive flashes of the flashlight are used to achieve even exposure of the image area, which the flashes are timed in such a way that each single flash is triggered at a point of time which is common to the integration or exposure time of as many successive sub-areas of the image sensor as possible. According to the invention, the successive light flashes are also timed in such a way that one and only one flash of the flashlight occurs during the integration or exposure time of each single sub-area. By the present invention, the significant advantage is attained that the invention minimizes the number of light flashes required for one image while it also secures that each sub-area of the sensor to be exposed at a different time is illuminated as evenly as possible.

Booting multiple processors with a single flash ROM

A method, apparatus and computer-usable medium are presented for loading firmware onto multiple processors. A firmware controller is coupled to multiple processors and a firmware memory. A service processor, by controlling the operation of the firmware controller, selects one or more of the multiple processors. Under the control of the service processor, the firmware controller sends firmware from the firmware memory to each of the selected processors, either sequentially or simultaneously. If one of the selected processors fails to fully execute the firmware from the firmware memory, the firmware controller notifies the service processor of that failure as well as the particular memory address in the firmware where the failure occurred.
