  • Publication number: 20100259847
    Abstract: A portable apparatus having an electronic control system and a control method thereof are provided. The portable apparatus comprises an operation system, an accessing device and a basic input/output system (BIOS), and the electronic control system comprises a G-sensor and an embedded controller (EC) for initializing the G-sensor, wherein the G-sensor senses the acceleration of the portable apparatus and compares the acceleration value with the threshold value. The operation system comprises an application program (AP) and an advanced configuration and power interface (ACPI). When the acceleration value is higher than the threshold value, the G-sensor sends out a first signal to the EC, and the EC sends out a second signal to the BIOS, and the BIOS sends out a third signal to the ACPI, and the ACPI sends out a fourth signal to the AP to give a park command for parking the reading head of the accessing apparatus.

  • Publication number: 20060221596
    Abstract: The present invention is aimed to provide an emitting light device of shoes. Optical fibers and nylon fibers woven into a leaflet luminescent panel exposed on any portion of shoes is electrified by a power source hidden in the shoe heel. The light source (LED or NEC ZIP) transmits light emissions to the ends of the woven fibers with irradiation effects. The emitting light device includes a battery base, PCB, battery, switch, LED or NEC ZIP, heat-shrink sleeve and fabric optic panels. In that, said luminescent panel and fiber optic bundles formed at the first and second end of the fabric optic panel respectively. A heat-shrink sleeve receives said fiber optic bundle and a luminous element at the first and second end respectively. A switch is closed to electrify the PCB and then lights the luminous element finally transmits the light emission to the luminescent panel with irradiation effects.

  • Patent number: 6888754
    Abstract: This invention provides a memory array and its peripheral circuit with byte-erase capability. The advantage of this invention is the ability to access bytes for program, erase, and read operations. This invention allows this access with the addition of one word line switch and one source line switch for each byte to be accessed for program, erase, and read operations. Also, this invention utilizes a new bias condition to lessen the voltage stress on the high voltage device. In addition, this invention utilizes separate and dedicated power supplies for the local word line driver circuits and for the local source line driver circuits. This is coupled with the partitioning of the main memory array into sub-arrays of 8 columns. This allows the placing of high voltage only on the selected 8 column (byte) subarray. This also substantially lessens the voltage stress on the memory cells and enhances long-term reliability.
