    Abstract: A tangible invitation card extends an invitation by displaying information with regard to the invitation. A settable real-time clock sets a predetermined time which is displayed on a screen on the invitation card of time remaining to a selected target date for an event or earlier RSVP date related thereto. The card is programmed such that as the target date is approached, one or more visual displays and/or sounds count down and announce the time left to the target date for the RSVP or event. The invitation card is programmed with the necessary information to enable it to perform its reminder mission.

  • Patent number: 7398379
    Abstract: Methods and apparatus are provided for conveying configuration data to a programmable logic device integrated circuit. When the configuration data is loaded into configuration memory on the programmable logic device integrated circuit, the programmable logic device integrated circuit performs custom logic functions. The programmable logic device integrated circuit or an associated configuration device integrated circuit may be provided with power conversion circuitry and transceiver circuitry. The power conversion circuitry converts received radio-frequency signals into power. The power from the power conversion circuitry is provided to the transceiver, loading, and configuration memory circuitry. The transceiver circuitry is connected to an antenna that receives wirelessly-transmitted configuration data and is used to transmit confirmation messages following successful loading of the configuration data into the configuration memory.

  • Patent number: 7394304
    Abstract: A semiconductor integrated circuit comprises a logic circuit unit, a signal control unit, a first signal selecting unit to a third signal selecting unit, and a first element electrode to a fourth element electrode. A part of signal lines of the logic circuit unit is connectable to different element electrodes, in accordance with the operating state of the logic circuit unit. The signal control unit generates connection information related to the connection of the signal lines to the element electrodes, thereafter sending the connection information to an external LSI. The connection is made after a retaining period, during which the element electrode concerned is maintained at high impedance, thereby avoiding unexpected failure. According to the present structure, the number of element electrodes required by the semiconductor integrated circuit can be reduced.

  • Patent number: 7391237
    Abstract: A system for FPGA (Field Programmable Gate Array) upgrade includes: an FPGA, a FLASH memory and a CPLD. The FLASH memory includes a first section configured to store a workable version of bit files for the FPGA and a second section configured to store a backup version of bit files for the FPGA. The CPLD is coupled to the FPGA and the FLASH memory. The CPLD is configured to download the bit files from the FLASH memory to the FPGA to provide the FPGA with functionality. As a result, the CPLD communicates with CPU to upgrade the bit files in the FLASH memory, and indicates to the CPU which version of bit files has been downloaded to the FPGA.

  • Patent number: 7385416
    Abstract: Circuits and methods of implementing flip-flops in dual-output lookup tables (LUTs). A flip-flop is implemented by programming a dual-output LUT to include a first function implementing a master latch and a second function implementing a slave latch. An output of the master latch is provided at a first output terminal of the LUT, and an output of the slave latch is provided at a second output terminal of the LUT. The output of the master latch (the first output of the LUT) is coupled to a first input terminal of the LUT, where it drives both the first and second functions. The output of the slave latch (the second output of the LUT) is coupled to a second input terminal of the LUT, where it drives the second function. A clock signal is provided to both first and second functions via a third input terminal of the LUT.

  • Patent number: 7378869
    Abstract: A lookup table (LUT) is programmable to function as a flip-flop. The LUT includes a plurality of memory cells, a plurality of transmission gates, and first and second logic gates. The transmission gates are coupled between the memory cells and an output terminal of the LUT to form a multiplexer circuit selecting one of a plurality of values stored in the memory cells and providing the selected value to the output terminal. First and second logic gates are included in two of the paths through the multiplexer, also providing first and second feedback paths within the LUT. These feedback paths enable the programmable implementation of first and second latches that form the flip-flop. Another subset of the memory cells can be optionally used to implement a function that drives the data input of the flip-flop.
