    Abstract: Psychoacoustic bass audio signal enhancement can be accomplished using a monotonic, asymmetric polynomial distortion. A non-linear process applies a monotonic, asymmetric polynomial distortion function that has continuous first and second derivatives to generate even and odd harmonics of missing fundamental frequencies. This polynomial distortion produces the desired psychoacoustic effect with a fairly rapid roll-off so as to avoid unpleasant aliasing. Moreover, the lack of first-order discontinuities prevents clicks or glitches.

    Abstract: Methods and apparatus for implementing a robust unicast/broadcast/multicast protocol are provided. In one aspect, a method of avoiding collision of intra-basic service set unicast, broadcast or multicast transmissions notifies stations in the basic service set of a reserved transmit opportunity for a unicast, broadcast or multicast transmission. Transmissions from at least one station in the basic service set are deferred until after the reserved unicast, broadcast or multicast transmit opportunity.

    Abstract: A system for adjusting the light uniformity of a monitor. The system comprises a camera for capturing a test pattern image on a display of the monitor and a controller configured to select the test pattern image and to cause the monitor to display the selected test pattern image. The controller receives the captured image from the camera and compares pixel values from the captured image to known pixel values associated with the selected test pattern image. The selected test pattern image has an ideal uniform light distribution and the captured image has a non-uniform light distribution. In response to the comparison, the controller calculates a compensation light distribution that may be combined with the non-uniform light distribution to generate a resulting image on the display of the monitor having a resulting light distribution that approximates the ideal uniform light distribution.

    Abstract: Embodiments are directed to switching of stations STA, access points APs and PCPs that are communicating through a wireless link from one frequency band to another. One embodiment is directed to switching of stations STA that are communicating through a tunneled direct link setup (TDLS) link from one frequency band to another. A multiband element may be added to a TDLS discovery request and TDLS discovery response frames to allow each of the stations communications through a TDLS to determine if the other station has multiband capability. In one embodiment, a pairwise transient key (PTK) is created for both a current band in which the stations STA are communicating and a new band over which the stations may communicate in the future. In this way there is no need to calculate a new pairwise transient key PTK for the new frequency band.

    Abstract: The invention discloses frame-based, on-demand spectrum contention methods and systems to share spectrum resources in cognitive radio networks in general and in Wireless Regional Area Networks (WRANs) having overlapping service areas in particular. As demand for increased spectrum usage arises, frames within synchronized superframes are allocated, on a frame-by-frame basis, based on independently chosen, equiprobable random numbers generated for each base station contending for transmission/reception use of the frames.

    Abstract: A leakage power control vector is loaded into existing test scan chain elements for application to circuit elements of a circuit in which the leakage currents are to be controlled. The vector is designed to configure the circuit elements into states in which leakage currents are reduced. A multiplexer selects the power control vector for loading into the scan chain elements, and a clock generator clocks the configuration vector into the scan chain elements. A sleep mode detector may be provided to configure the multiplexer to select the power control vector and to operate the clock generator to clock the power control vector into the scan chain elements when a sleep mode of the circuit is detected.

    Abstract: A boost circuit is used for power factor correction (PFC). In a low power application, transition mode control is utilized. However, switching frequency varies with different input voltages, and over a wide input voltage range, the switching frequency can become too high to be practical. To address this issue, a boost circuit is provided whose effective inductance changes as a function of input voltage. By changing the inductance, control is exercised over switching frequency.

    Abstract: A method and apparatus for recovering a content signal from media stream protected by a digital rights management (DRM) system. A content access device includes a network interface configured to receive the protected media stream from a remote content provider via a network and a plurality of distinct DRM components corresponding to DRM systems supported by the content access device. A content extraction unit is operable to select a DRM component of the plurality of DRM components and execute the selected DRM component to recover a content signal from the protected media stream. When a search engine is used to discover available content, a list of references to available content is presented to the user, the presentation being dependent upon whether or not the content is protected by a DRM system supported by the content access device.
