    Abstract: A computer enclosure includes a frame portion and a battery holding structure. The frame portion defines a battery receiving groove for receiving a battery, a first sliding groove and a second sliding groove communicating with the battery receiving groove. The battery holding structure includes a first locking member movably received in the first sliding groove, a second locking member movably received in the second sliding groove, and a spring. The first locking member includes a first latching block. The second locking member includes a second latching block. The spring is compressed between the second locking member and an inner surface of the second sliding groove and configured to provide a force to push the second latching block into the battery receiving groove.

  • Patent number: 8158402
    Abstract: A high-yield bacterial strain for producing acetoin named Bacillus pumilus XH195 has been deposited in a microorganism deposit center in Germany. The deposit number is DSM 16187. The bacteria of the strain are rod-shaped, 1.5 ?m to 3.0 ?m in length, and 0.6 ?m to 0.7 ?m in diameter. The colony color of the bacterial strain is yellow or white. The strain has the typical fatty acid profile of Bacillus and its physiological and biochemical characteristics align with those of Bacillus pumilus. When the bacteria of strain were cultured at 37° C. for 60 hours with shaking, the yield of acetoin could reach 63.0 g/L or 58.1 g/L, when glucose or sucrose was used as the substrate, respectively.

  • Patent number: 7965157
    Abstract: Briefly, in accordance with one embodiment of the invention, a resonator such as an electromechanical resonator may be coupled with a cancellation network to reduce and/or cancel an anti-resonance effect in the resonator, which may be due to, for example, a static capacitance inherent in the resonator. Cancellation of an anti resonance effect from the resonator response may allow a resonance effect of the resonator to be a predominant effect to allow the resonator to be utilized as a bandpass filter having a relatively higher Q, for example in a bandpass sigma-delta modulator that may be utilized in a digital RF receiver.
