  • Publication number: 20130058402
    Abstract: Lossless video data compression is performed in real time at the data rate of incoming real time video data in a process employing a minimum number of computational steps for each video pixel. Each pixel 8-bit byte is converted to a difference byte representing the difference between the pixel and its immediate predecessor in a serialized stream of the pixel bytes. This reduces the dynamic range of the data. Any carry bits generated in the subtraction process of two's complement arithmetic are discarded. This reduces the data by a factor of two. Finally, the 8-bit difference pixel bytes thus produced are subject to a maximum entropy encoding process. Such a maximum entropy encoding process may be referred to as a minimum length encoding process.

  • Patent number: 8376303
    Abstract: A support includes a base, an upper cover connected to the base, a support plate, and a base. The upper cover includes a recess for receiving a bottom of an electronic device, and two openings defined in a bottom of the recess at two opposite ends of the recess for movably receiving pressing members. A pair of pressing members are respectively moveably received in the two openings. Each of the pair of pressing members includes a protruding post rotatably connected to the base. Two elastic members arrange in the base to respectively apply a recoiling, spring force to the pressing members when compressing and releasing. When urged by an electronic device, the pressing members deflect downward to form a first receiving space; and when the electronic device is removed, the pressing members are recoiled by the elastic members and forms a second receiving space.

  • Publication number: 20130028307
    Abstract: In a method of adjusting a modulation and coding scheme (MCS) level for a transmission on a communication channel between a base station and a mobile terminal, at the base station: a target value for an error metric is defined; the error metric is measured; an MCS offset based on a degree of deviation of the measurement of the error metric from the target value is determined; an indication of a channel quality measurement for the communication channel is received from the mobile terminal; a pre-adjusted MCS level corresponding to the indication of the channel quality measurement is determined using a fixed mapping between a set of channel quality levels and a corresponding set of MCS levels; an adjusted MCS level is determined by adding the MCS offset to the pre-adjusted MCS level; and the adjusted MCS level is assigned to the transmission.

  • Publication number: 20130027855
    Abstract: A fastening mechanism includes a nosepiece, a rotating unit, a torsion spring and a locking unit. The nosepiece is disposed at one side of an object removably disposed in a housing. The rotating unit includes a wheel body including a peripheral wall with an outer peripheral friction surface disposed in frictional contact with a side surface of the nosepiece and a rotating disc formed with a notch. The rotating unit is operable to rotate in a releasing direction relative to the housing as biased by the torsion spring to move the object away from the housing through an opening by virtue of the frictional contact. The locking unit releasably engages the rotating disc to dispose the rotating unit at a stopped position.

  • Publication number: 20120293377
    Abstract: A display device includes a display panel and a directional antenna. The directional antenna is disposed behind or under the display panel for radiating or receiving wireless signals. The radiating path of the directional antenna is at a specific angle with respect to a horizontal plane for receiving surrounding wireless signals. Or, the signals radiated from the directional antenna may be reflected or refracted to regions above or in front of the display device by a back-side barrier or penetrate a back-side barrier which does not cause large electromagnetic degradation, thereby receiving wireless signals originated from the front-side or back-side of the display device.

A first step is to convert each pixel 8-bit byte to a difference byte representing the difference between the pixel and its immediate predecessor in a serialized stream of the pixel bytes.
