  • Publication number: 20130122471
    Abstract: Laser target practice using an ultra-violet light emitting laser that is pulsed on when a weapon trigger is pulled. The LTV laser light pulse illuminates a spot on a target having a phosphorus coating on a face thereof. The phosphorus within the illuminated spot glows for a certain time thereby visually indicating a location of the spot on the target. The UV laser light pulse may also illuminate a spot on a target having a photochromic paint coatings on a face thereof. The photochromic paint coatings within the illuminated spot changes color thereby indicating a location of the spot on the target.

  • Patent number: 7186594
    Abstract: A high voltage ESD-protection structure is used to protect delicate transistor circuits connected to an input or output of an integrated circuit bond pad from destructive high voltage ESD events by conducting at a controlled breakdown voltage that is less than a voltage that may cause destructive breakdown of the input and/or output circuits. The ESD-protection structure is able to absorb high current from these ESD events without snapback that would compromise operation of the higher voltage inputs and/or outputs of the integrated circuit. The ESD-protection structure will conduct when an ESD event occurs at a voltage above a controlled breakdown voltage of an electronic device, e.g., diode, in the ESD protection structure. Conduction of current from an ESD event having a voltage above the electronic device controlled breakdown voltage may be through another electronic device, e.g.

  • Patent number: 7002218
    Abstract: An ESD-protection structure is located substantially under an integrated circuit bond pad. This ESD-protection structure is formed as a low capacitance structure by inserting a forward diode between the bond pad and the ESD clamp circuit. Placing the ESD-protection structure under the bond pad eliminates parasitic substrate capacitance and utilizes a parasitic PNP transistor formed from the inserted forward biased diode. The ESD-protection structure includes adjacent alternating P+ and N+ diffusions located substantially under a bond pad to be ESD protected. The P+ diffusions are connected to the bond pad metal with metal vias through an insulating layer. The N+ diffusions are adjacent to the P+ diffusions. An N+ diffusion surrounds the N+ and P+ diffusions, and ties together the N+ diffusions so as to form a continuous N+ diffusion completely around each of the P+ diffusions. An N? well is located substantially under the N+ and P+ diffusions.

  • Patent number: 6931075
    Abstract: A bistable memory device changes logic state each time an event occurs. The bistable memory device has an logic output coupled to a digital processor input. The digital processor reads the logic state of the bistable memory device from its logic output and compares the logic state read to a stored previous logic state obtained from a previous read. If the logic state read and the stored previous logic state are the same, then no event has occurred during the time between the read and previous read of the logic states of the bistable memory device. If different, then an event has occurred during the time between the read and previous read of the logic states of the bistable memory device. The event detection may be used in combination with a digital system communicating by serial digital data transmissions.

  • Patent number: 6593639
    Abstract: A matching capacitor array is implemented on a single, monolithic integrated circuit. The array features a matrix of bottom electrodes and a plurality of continuous top electrode strips, where each continuous top electrode strip spans numerous bottom electrodes. The conductive contacts for each continuous top electrode strip are removed from the capacitor interface to the terminal ends of each of the continuous top electrode strips. The invention seeks to match or control parasitic and fringe capacitance, rather than to eliminate or minimize such capacitances. By creating a matched array, the parasitic and fringe capacitances of each matching capacitor unit cell are incorporated into the total capacitance of the unit cell.

  • Patent number: 6321319
    Abstract: A system for allowing a two word jump instruction to be executed in the same number of cycles as a single word jump instruction, thereby allowing a processor system to increase memory space without reducing performance. A first address bus is coupled to the linearized program memory for sending addresses of instructions to be fetched to a linearized program memory. A pointer is coupled to the first address bus for storing an address location of a current instruction in the linearized program memory to be fetched and for placing the address location of the current instruction to be fetched on the first address bus. A second address bus is provided and has one end coupled to the output of the program memory and a second end coupled to the first address bus.

  • Publication number: 20010030905
    Abstract: A microcontroller architecture that adds a dedicated bit in the op-code decode field to force data access to take place on a page of the random access memory (RAM) for that instruction. This allows the user to have any page selected and still have direct access to the special function registers or the register variables that are located on a pre-defined page of the RAM. The setting of the dedicated bit will not affect the current operation of the microcontroller nor will the setting of the bit modify the currently selected address stored in a page select register currently being used by the microcontroller.
