  • Patent number: 7669232
    Abstract: Systems and methods for authentication using paired dynamic secrets in secured wireless networks are provided. Each authenticated user is assigned a random secret generated so as to be unique to the user. The secret is associated with a wireless interface belonging to the user, so that no other wireless interface may use the same secret to access the network. The secret may be updated either periodically or at the request of a network administrator, and reauthentication of the wireless network may be required.

  • Publication number: 20090168393
    Abstract: A polarized light illumination device is described, which includes a light source, a polarizer, a reflector, and a polarized light converter. The light source generates light. The reflector is used for reflecting light generated by the light source towards the polarizer. The polarizer allows a first polarized light to pass through, and reflects a second polarized light. The polarized light converter reflects the light irradiated on the polarized light converter and performs a polarization conversion. A plane where the polarized light converter is located is substantially perpendicular to the polarizer.

  • Publication number: 20070153239
    Abstract: A light-beam generator and a projecting system having the light-beam generator are proposed in the present invention. The light-beam generator includes an optical element and a light-emitting diode, wherein the optical element further includes a non-spherical reflecting curved surface which at least has a focus. Also, the light-emitting diode is located at the focus of the optical element for emitting light to the reflecting curved surface to form a light beam which is guided in a specific direction. By such arrangement, an output efficiency of light beams can be improved and a heat dissipation requirement can be reduced. Additionally, the light-beam generator proposed in the present invention can be applied to a projecting system having illuminant with specific polarized directions, so as to eliminate various prior-art drawbacks.

  • Publication number: 20070130456
    Abstract: Initiating a virtual presence at a physical access point in response to a request for a service from a wireless access device is provided. A particular wireless service may be provided to a subscriber on an on-demand basis according to location and/or type of service requested. The service may be terminated when demand for the service comes to an end whereby a common wireless service infrastructure may be shared amongst service providers thus eliminating the need for radio channel coordination and otherwise enhancing service quality for those service providers.

  • Patent number: 6553793
    Abstract: A motorcycle disc brake lock includes a lock body, a rotary base, a deadbolt, a locking card, a coil spring, a lock column and a twist spring. In using, a key is applied to turn around the rotary member of the lock column to actuate the rotary base rotate. The engage members of the locking card are guided and actuated to move up and get into the engage recesses of the rotary base by the sloped surfaces of the two prop projections in the chamber of the lock body. Thus, the deadbolt is moved upward, forming an unlocked condition. For locking, only insert the disc brake of a motorcycle into the deep opening of the lock body to slightly push up the deadbolt and force the locking card to move into the slide slots of the rotary base. Thus, the deadbolt is pushed down to have its bottom end inserted in a lock hole to lock the disc brake.
