    Abstract: An improved method for converting between two color spaces such as the RGB and YIQ color on a 32 bit microprocessor. The present invention only requires in total number of operations three table look-ups, two adds, two barrel shifts and two masking operations. In terms of speed it is believed that the present invention is optimal for microprocessors such as 32 bit microprocessors.

    Abstract: Transforms such as the DCT are useful for image compression. One close relative of the DCT is preferred for its arithmetic simplicity. A method and apparatus is described whereby the quantization operates with speeds comparable to 16 bit transforms yet the mean squared error is comparable to that of a 32 bit transform. The factorability of the transform into a relatively rapid set of additions and a set of multiplications permits an efficient pipelined data flow wherein the addition sections of the vertical and horizontal transforms are performed by the same hardware prior to a final multiplication.

    Abstract translation: 像DCT这样的变换对于图像压缩是有用的。 DCT的一个紧密相对于其算术简单性是优选的。 描述了一种方法和装置,其中量化以与16位变换相当的速度进行操作,但是均方误差与32位变换的均方误差相当。 将变换成相对快速的一组加法和一组乘法的因素允许有效的流水线数据流,其中垂直和水平变换的相加部分在最终乘法之前由相同的硬件执行。

    Abstract: A computer-implementable method, system and computer-usable medium includes a virtual contact group that can be dynamically created, in response to a particular user input such as, for example, registration by the user with a particular organization and/or facility. The virtual contact group generally includes a plurality of key or designated personnel. The virtual contact group is associated with the user. The designated personnel are then allowed to communicate electronically with one another within the virtual contact group to provide a coordinate service to the user. The virtual contact group is defined based on a user profile associated with the user. The virtual contact group can be stored within one or more memory locations of a computing device associated with one or more designated personnel among the virtual contact group. Such a computing device can be, for example, a wireless communication device capable communicating with the network and/or a server associated with the network.

    Abstract: A wireless communication system operating in the presence of the periodic noise signals such as from a microwave oven, the communication system, including at least two wireless communication stations with each station including a transceiver, each such transceiver. Each transceiver includes a detector for detecting periodic noise signals and producing a first signal indicating the presence of noise signal's quiescent period and second signals indicating the end of quiescent periods of such periodic noise signal. A controller responsive to the first and second noise signals controls the transceiver to provide effective communication with an other transceiver which minimizes the noise effect of the periodic noise signal. The transceiver transmits information concerning the detected quiescent period for use by the other transceiver to determine when to transmit during such quiescent period.
