  • Patent number: 8829990
    Abstract: An amplifier may include two or more pulse-width modulators controlling respective sets of switches to produce an amplified version of a source signal. A positive DC-offset based on the source signal may be applied to the pulse-width modulator controlling one respective set of switches, and an equal value negative DC-offset may be applied to the pulse-width modulator controlling the other respective set of switches, to provide an effective offset between the respective points in time of the rising/falling edges of the different pulse-width modulated control signals. The addition of alternating positive and negative DC-offset values doesn't affect the output load, and doesn't degrade the signal. The DC-offsets may be added at a frequency selected to be beyond the signal baseband, and the value of the small input signal level may be determined using an RMS level comparator or similar measurement technique.

  • Patent number: 8807268
    Abstract: A loudspeaker comprises a reflex port located within the enclosure at a point substantially co-incident with a nodal surface of at least one resonant mode within the enclosure. The amplitude of that resonance at the input to the duct is minimized, hence assisting in filtering out the effect of that resonance without needing absorptive material. Ideally, it is placed at the intersection of two or more nodal surfaces.

  • Patent number: 8756665
    Abstract: A user authenticates to a Web- or cloud-based application from a browser-based client. The browser-based client has an associated rich client. After a session is initiated from the browser-based client (and a credential obtained), the user can discover that the rich client is available and cause it to obtain the credential (or a new one) for use in authenticating the user to the application (using the rich client) automatically, i.e., without additional user input. An application interface provides the user with a display by which the user can configure the rich client authentication operation, such as specifying whether the rich client should be authenticated automatically if it detected as running, whether and what extent access to the application by the rich client is to be restricted, if and when access to the application by the rich client is to be revoked, and the like.

  • Patent number: 8742841
    Abstract: An amplifier may use pulse-width modulators controlling respective sets of switches to produce an amplified version of a source signal. A phase locked loop in the amplifier may generate a differential clock signal. A first processing element operating according to a first supply voltage may generate a PWM signal representative of the source signal, and also generate a clock enable signal corresponding to the differential clock signal. A second processing element (PE2) may receive the differential clock signal, the PWM signal, and the clock enable signal, and level shift the PWM signal and the clock enable signal to operate according to a second supply voltage, and may generate a resampling clock signal from the differential clock signal according to the level shifted clock enable signal. The PE2 may provide a PWM output signal representative of the source signal by resampling the level shifted PWM signal with the resampling clock signal.

  • Publication number: 20140107195
    Abstract: A water-swellable linear polyurethane polymer is formed by reacting a polyethylene oxide (e.g. PEG 4000 to 35,000), a difunctional compound (e.g. a diamine or diol such as 1,10-decanediol) with a diisocyanate. The ratio of the three components is generally in the range 0.1-1.5 to 1 to 1.1-2.5. The polyurethane is water-swellable in the range 300 to 1700% and soluble in certain organic solvents such as dichloromethane. It can be loaded with pharmaceutically active agents, particularly of high molecular weight, to produce controlled release compositions, such as pessaries etc.

  • Publication number: 20140059671
    Abstract: Information and data stored by a mobile device is protected by comprising applying password-protection to the locally-stored information without persistently storing the corresponding password locally. Rather, the corresponding password is stored by a remote password server. In response to a trigger event on the mobile device, such as an unlocking action by the user, a request is sent by the mobile device to the password server to retrieve the corresponding server, and the corresponding password is returned to the mobile device. The mobile device can then use the password to access the protected information. If the user determines that the mobile device is lost, stolen, or out of the user's physical control, the user may access the password server and disable the sending of the password to the mobile device, thereby thwarting attempts to access the protected data on the mobile device.

  • Publication number: 20140023149
    Abstract: In a method of analyzing an input video sequence, pixels of synthesized images of an output video sequence are associated with respective directions of regularity belonging to a predefined set of directions. A first subset of candidate directions is determined from the predefined set of directions for a region of a first image of the output sequence. For a corresponding region of a second synthesized image of the output sequence following the first image, a second subset of candidate directions is determined from the predefined set of directions, based on images of the input sequence and the first subset of candidate directions. The directions of regularity for pixels of this region of the second synthesized image are detected from the second subset of candidate directions. The recursive determination of the subsets of candidate directions provides a sparse geometry for efficiently analyzing the video sequence.
