Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.

Abstract: An open basket of a resilient mesh material having first and second side edges of a frictional flexible material. The side edges are adapted to provide for positioning of the basket either immediately partially between a vent cover and the duct, or alternatively, fully within the duct at a location immediately below and spaced apart from, the vent cover. The mesh size of the basket is chosen to preclude the passage therethrough of commonly experienced objects, such as rounded objects such as marbles, elongated objects such as nail clippers, pens, coins, etc. any of which may pass through the slots defined in the vent cover.

Abstract: A power supply for achieving high output power levels at a high efficiency from a compact profile. The power supply includes a current regulator which receives a source voltage and outputs a signal having a constant current. The signal output from the regulator is provided to a center tap of a primary winding of a transformer. The ends of the primary winding of the transformer are connected to switches which are controlled by a switch driver. The transformer, switches and switch driver form a resonant oscillator. The switch driver is connected to a zero voltage level detector which detects when the voltage of the signal output from the current regulator reaches a zero level. When such a detection is made, the zero voltage level detector provides an enable signal to the switch driver to operate the switches in a push-pull mode. By operating the switches in a push-pull mode, the energy balance and resonance of the transformer can be maintained.
