摘要： The present disclosure relates to systems and methods for dynamic load balancing in a wireless network, such as a wireless local area network (WLAN) and the like. Specifically, the present invention periodically provides dynamic load balancing of mobile devices associated with a plurality of wireless access devices. This may include determining an optimum load and instructing wireless access devices that are overloaded to disassociate some mobile devices based upon predefined criteria. This disassociation is performed in a manner to minimize disruption by disassociating mobile devices with low usage, with close proximity to underutilized wireless access devices, and mobile devices not currently operating critical applications, such as voice.

摘要： A stepper motor device uses compensating non-sinusoidal driving values to compensate for operational non-sinusoidal drive characteristics of a motor of the device due to at least design and manufacturing imperfections in the motor. The compensating non-sinusoidal driving values may be derived using back electromagnetic force produced from the motor or using measured rotational positions of the motor when the motor is driven using known driving values.

摘要： An improved circuit and method for detecting dielectric breakdown and ground fault conditions is provided. The circuitry and method of the present invention include taking a continuous voltage reading of the high voltage battery and sampling the continuous voltage reading of the high voltage battery at a fixed time interval. The circuitry and method calculate a change in the continuous voltage reading of the high voltage battery over the change in time and repeatedly calculate an optimum fixed time interval and an optimum change in voltage over time. Storage of the optimum fixed time interval and optimum change in voltage over time provides for repeatedly comparing the optimum change in voltage over the fixed time interval to the constant voltage of the high voltage battery to calculate the resistance of the dielectric breakdown fault. The calculation of the resistance of the dielectric breakdown fault is carried out independently of the capacitance of the electric circuit. The circuit and method provide adjustment of the optimum fixed time interval to improve the speed of the comparison of the optimum change in voltage over time to the constant voltage of the high voltage battery to calculate the resistance of the dielectric breakdown fault.

摘要： A method (100) of controlling an inverter in an electronic ballast for at least one gas discharge lamp protects the inverter from damage due to lamp fault conditions, and provides enhanced noise immunity and multiple ignition attempts for low-temperature lamp starting. The method (100) includes repeating a filament preheating step and a frequency shifting step up to a predetermined number of times in order to facilitate lamp ignition under low-temperature conditions and to verify the legitimacy of a detected lamp fault.

摘要： An electronic ballast (300) for powering at least one gas discharge lamp (10) includes an inverter (400), an output circuit (700), a lamp fault detection circuit (800), and an inverter control circuit (500). Ballast (300) operates according to an inverter control method (100) that includes repeating a filament preheating step and a frequency shifting step up to a predetermined number of times in order to facilitate lamp ignition under low-temperature conditions and to verify the legitimacy of a lamp fault. Inverter control circuit (500) is well-suited for implementation as a custom integrated circuit. Ballast (300) optionally includes an overcurrent detection circuit (820') with an adjustable lamp fault detection threshold that provides decreased sensitivity during lamp starting and enhanced protection after lamp ignition.

摘要： A system comprises a series of passive RFID tag sensors each embedded on top of its own matching antenna inside a flexible substrate. The sensors are driven by a controller-transceiver. The controller-transceiver sends RF signals through an antenna to each RFID tag sensor and receives data transmitted back from the same sensors. Sensors are embedded in a flexible substrate positioned under an unaltered incontinence absorbent pad and juxtaposed to derive further information. Multiple sensors provide sensing of physical-environmental data in addition to moisture. The controller makes intelligent and positive incontinence determinations by relating data to profiles indicative of correlation to incontinence conditions.
