摘要： The present invention is directed to a sigma-delta digital to analog converted (DAC) including a digital-sigma delta modulator, a decimation filter, and a multi-bit DAC. The digital sigma-delta modulator receives a digital input signal and produces a quantized digital signal therefrom. The decimation filter receives the quantized digital signal and produces a decimated digital signal therefrom. The multi-bit DAC receives the decimated digital signal and produces an analog output signal therefrom. The analog output signal is representative of the digital input signal.

摘要： A fan monitoring system for an electronics system or a computer system. The fan monitoring system includes a fan which produces a rotation signal, where the rotation signal is a function of the fan rotating. The fan monitoring system also includes a detection circuit responsive to the rotation signal and producing an operating signal indicative of the fan rotating. The fan monitoring system also includes a fan detection circuit having a primary connection point capable of being electrically coupled to the fan. The fan detection circuit provides a detection signal indicative of whether or not the fan is electrically coupled to the fan detection circuit. The fan monitoring system further includes an I/O circuit for receiving the fan detection signal and the operating signal. The I/O circuit providing I/O signals to a host computer system as determined by the operating signal and/or the detection signals.

摘要： An automated window system and method for a building utilizes a pair of gas springs to bias a window panel outward from a corresponding frame. A force opposing the gas springs is supplied by a motor driven spindle selectively winding and unwinding a cord coupled to the window panel sash adjacent the jamb portion of the frame and window. The cord is slidably retained to the jamb portion of the window sash through a pair of threadable pulls in order to equalize the forces supplied opposing the gas springs in the event of uneven winding of the cord due to buffeting or other forces while the window panel is being moved between an "open" to a "closed" position thereof.

摘要： A system and method are used to provide uncorrelated code hopping in a communications system. A shift register receives data. The shift register is clocked to shift the data. A scaler performs a scaling operation on the data with a numerical value of active codes. A truncator truncates the scaled data to its seven most significant bits to produce a pseudo random hop number. A code matrix shifter circularly shifts the active codes in a code matrix based on the pseudo random hop number to produce a circularly shifted code. A transmitter transmits the circularly shifted code.

摘要： Methods and apparatuses for spectrally shaping mismatch errors in a multi-bit digital to analog converter (DAC). In an embodiment, the multi-bit DAC is constructed from K separate multi-element sub-DACs, where K and the number of elements in each sub-DAC are each preferably greater than two. A received digital input code is split into a set of K sub-codes corresponding to the digital input code. The set of K sub-codes can have one of at least N different sub-code orders that specify an order of each of the K sub-codes with respect to one another, where N>2. A sum of the K sub-codes equals the digital input code. One of the at least N different sub-code orders is selected using a shuffling algorithm. Then, each sub-code in the set of K sub-codes is output in accordance with the selected sub-code order.

摘要： A system and method is provided for supplying power over a home phone line network in a manner that is interoperable with other voice and data services operating on the same network. The system includes a power source coupled to the home phone line network. The power source includes an AC signal generator that generates an AC signal at a selected frequency. The power source also includes a band pass filter for removing unwanted harmonics from the AC signal, thereby generating a filtered AC signal for powering one or more devices on the home phone line network. One or more devices attached to the home phone line network, such as a telephone adapter or telephone, receives the filtered AC signal. Each device comprises a second band pass filter and an AC/DC converter. The second band pass filter passes the filtered AC signal to the AC/DC converter and prevents the introduction of undesired harmonics onto the home phone line network from the AC/DC converter. The AC/DC converter converts the filtered AC signal to a DC signal used for powering the device.
