A modified push-pull booster circuit is proposed, wherein two alternately switching transistors are disposed on the primary winding of a transformer, and a bridge rectifier and a charging circuit are disposed on the secondary winding; wherein the bridge rectifier has a pair of inductors with inductive coupling installed on the first half and second half of the circuit. The push-pull circuit uses series inductance to step up the bus voltage, and, because of the degaussing effect when current is induced on the inductors, the inductance of the inductor can be decreased even without using snubber circuit, thus decreasing the peak voltage of the bridge rectifier, and balancing the magnitude of current flow in the secondary winding. By reducing the turn ratio on the transformer windings, the operating efficiency of the booster circuit can be considerably improved.

A verification method or apparatus applied in a Wireless Local Area Network (WLAN) includes learning an Internet Protocol (IP) address assigned to a station; sending the IP address to a managing device that is managing the access device and receiving, from the managing device, a determination of whether the IP address is used by another station; and verifying a data packet sent by the station by using an IP address that is not used by another station as reported by the managing device.

A driver circuit receiving wireless communication over a wireless network is disclosed. The driver circuit includes a lighting load, a main driver, and an auxiliary driver. The lighting load is selectively illuminated based on an output voltage being provided to the lighting load that is at least a forward voltage of the lighting load. The wireless communication is indicative of whether the lighting load is to be illuminated. The main driver is for controlling current and voltage within the driver circuit such that if the wireless communication indicates the lighting load is to be illuminated, then the current delivered to the lighting load is regulated by the main driver, and if the wireless communication indicates the lighting load is not to be illuminated, then the output voltage delivered to the lighting load is controlled by the main driver is below the forward voltage.

An approach is provided for providing a trust level to access a resource. A system receives a request at a device, from a first user, to access a resource associated with a second user. The resource is further associated with a predetermined privacy level. The system calculates a trust level between the first user and the second user based, at least in part, on a trust metric. The system then determines whether the trust level meets the predetermined privacy level and grants an access right to the resource based, at least in part, on the determination.
