  • Publication number: 20150364933
    Abstract: The present invention relates to an emergency battery activating assembly applied to car or motorcycle batteries, including at least a preset power supply device, a preset battery, and an activating device. The battery includes at least a conductive portion with a detect voltage value. The activating device is electrically connected to the power supply device and includes an input end, a reference voltage value, and a comparison unit. The input end is electrically connected to the conductive portion. The reference voltage value is set at below 0.5V. The comparison unit is electrically connected to the input end and is used to compare the detect voltage value and the reference voltage value. When the input end is electrically connected to the conductive portion, if the detect voltage value is larger than the reference voltage value, the activating device would activate the power supply device and provide power to the battery.

  • Patent number: 8508993
    Abstract: Various discussed approaches improve the over erase issue and the coupling effect, and include (A) multilevel contacts between (i) the first outer selected word line of an erase group, and (ii) the first unselected word line outside the ease group neighboring the first outer selected word line; (B) a sufficient separation distance between (i) the first outer selected word line of an erase group, and (ii) the first unselected word line outside the ease group neighboring the first outer selected word line. These are examples of electrically isolating (i) the first outer selected word line of an erase group, from (ii) the first unselected word line outside the ease group neighboring the first outer selected word line.
