摘要： Electronic lighting ballast in a facility intentionally presents a non-unity power factor load to an inductive or capacitive power supply, such a capability being used to correct the power factor for a larger facility employing different types of loads. Electronic lighting ballast is also used to intentionally generate specified harmonics of a certain phase and amplitude to a power source, and further, the method, apparatus and system uses such a capability to cancel undesirable harmonics generated by other equipment in a larger facility. A method of employing a communications protocol between an electronic ballast and a facility control or monitoring system, such that the system can communicate with many adjustable ballast's in a facility, and direct the ballast's, collectively or individually, to change their power factor or light output status or harmonic characteristics.

摘要： A direct conversion tuner down-converts television signals, cable signals, or other signals directly from an RF frequency to an IF frequency and/or baseband, without an intermediate up-conversion step for image rejection. The direct conversion tuner includes a pre-select filter, an amplifier, an image reject mixer, and a poly-phase filter. The pre-select filter, amplifier, and the image reject mixer can be calibrated to provide sufficient image rejection to meet the NTSC requirements for TV signals. The entire direct conversion tuner can be fabricated on a single semiconductor substrate without requiring any off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.

摘要： A system and method of creating a highly efficient digital amplifier which can take either analog or digital inputs, and produce a high power accurate representation of the input to drive speakers or other low impedance load is described. The system employs a transition detector and delay unit which allows the comparator of the signal modulator to ignore its inputs for a pre-determined number of subsequent clock cycles once an output transition has been detected. Through the use of faster clocks and variable clock cycle skips upon the comparator's output transition, finer resolution of the feedback's clock period for noise-shaping purposes is achieved. Finer resolution of the clock period allows the present invention to employ a more aggressive noise-shaping than previously possible. In another aspect of the invention, additional delta-sigma modulator noise suppression is obtained by using the common bridge implementation of the power output stage with the improvement of configuring the bridge to create a 3-state condition instead of the conventional 2 states. By controlling the two halves of the bridge independently of one another, an output with 3 states makes for improved noise shaping performance.

摘要： Systems, methods and devices for managing communications across a wireless network to maximize the operations for transmission and utilization of the network or portions thereof in conjunction with wireless devices and applications that involve communication of information over a wireless network by evaluating the existing load on the wireless network and modifying or reducing the forthcoming demand of a mobile device using the network. A management server on the wireless network utilizes information about a wireless device communication to generate an estimate of the remaining unused or available upload capacity of that portion of the wireless network serving the particular wireless mobile device. The wireless mobile device applications that utilize network communications may be regulated to adjust their operations to function within the reduced network capacity.

摘要： A system and method for facilitating the authentication of wireless devices in an environment with multiple wireless networks. A user wishing to join an operating wireless network can bring his wireless device within close physical proximity, for example, less than one meter, of a device in the network that he wishes to join. The user then presses an authenticate button, which causes both devices to enter a low transmission power mode. In such case, the devices are only capable of operation within the close proximity. Being in low power mode will diminish the possibility of eavesdropping on the authentication process. Power down mode also reduces the amount of message traffic in the area and saves scarce power and processing resources at the nodes, which are now out of range. Authentication then takes place in low power mode and once completed, both devices resume normal power levels and continue communicating normally.
