  • Patent number: 8755806
    Abstract: A transmission of feedback information from a secondary to a primary node occurs in a plurality of N logical time durations. The secondary node receives an allocation of resources comprising a plurality of resource elements on an uplink shared data channel. The secondary node generates feedback information in response to transmissions from the primary node and normally transmits feedback information to the primary node on a control channel. On occasion, the secondary node receives a trigger from the primary node. In response to the trigger, the secondary node transmits the feedback information using a subset of the allocated resource elements on the uplink shared data channel.

  • Patent number: 8753944
    Abstract: A method of fabricating a Metal-Oxide Semiconductor (MOS) transistor includes providing a substrate having a substrate surface doped with a second dopant type and a gate stack over the substrate surface, and a masking pattern on the substrate surface which exposes a portion of the substrate surface for ion implantation. A first pocket implantation uses the second dopant type with the masking pattern on the substrate surface. At least one retrograde gate edge diode leakage (GDL) reduction pocket implantation uses the first dopant type with the masking pattern on the substrate surface. The first pocket implant and retrograde GDL reduction pocket implant are annealed. After annealing, the first pocket implant provides first pocket regions and the retrograde GDL reduction pocket implant provides an overlap with the first pocket regions to form a first counterdoped pocket portion within the first pocket regions.

  • Patent number: 8755877
    Abstract: A mobile system for analyzing ECG data includes an analog front end module coupled to a mobile consumer device. The analog front end module is configured to collect ECG data from one or more leads and is operable to convert the analog ECG data to digital ECG data. The mobile consumer device is coupled to receive the digital ECG data, and is configured to perform QRS detection using a filter whose cutoff frequency is adapted to noise level in real time. The ECG signal is amplified non-linearly and three windowed threshold signals (D, E, J) are derived. The cutoff frequency for the QRS detection is dynamically selected as a function of the threshold signals. A sample in the amplified signal is identified to be a heart beat point only when the sample value is equal to the first threshold signal and greater than the filtered threshold signal.

  • Patent number: 8753952
    Abstract: Ferroelectric capacitor structures for integrated decoupling capacitors and the like. The ferroelectric capacitor structure includes two or more ferroelectric capacitors connected in series with one another between voltage nodes. The series connection of the ferroelectric capacitors reduces the applied voltage across each, enabling the use of rough ferroelectric dielectric material, such as PZT deposited by MOCVD. Matched construction of the series-connected capacitors, as well as uniform polarity of the applied voltage across each, is beneficial in reducing the maximum voltage across any one of the capacitors, reducing the vulnerability to dielectric breakdown.

  • Publication number: 20140161252
    Abstract: Embodiments of the invention provide methods for key fob to control unit verification, retention, and revocation. After an initial pairing between a key fob and a control unit, the devices share a secret operation key (OpKey). For verification, the key fob sends the 8 lowest-order bits of a 128-bit counter and some bits of an AES-128, OpKey encrypted value of the counter to the control unit. For key revocation and retention, the control unit is prompted to enter an OpKey retention and revocation mode. Subsequently, each of the remaining or new key fobs is prompted by the user to send a verification message to the control unit. When the control unit is prompted to exit the OpKey retention and revocation mode, it retains the OpKeys of only the key fobs that sent a valid verification message immediately before entering and exiting the OpKey retention and revocation mode.

    Abstract: A mobile device, such as a smart phone, is provided with a camera and a projector. A user may select a still image or a video sequence and project it onto a viewing surface using the mobile device. Once the viewer selects a preferred perspective view frame, the image frame may be pinned to the viewing surface. After that, the viewer may move the projector to different positions while holding the projector, or sit the projector on a table and the viewed image will be maintained in the same perspective view frame as the initial selected view.

  • Publication number: 20140159950
    Abstract: A Global Navigation Satellite System (GNSS) receiver determines a measurement error covariance from a reference position and a set of measured pseudoranges from a set of GNSS satellites. The position and velocity solution is determined from the measurement error covariance and the set of measured pseudoranges. The measurement error covariance is determined as function of the difference between a reference pseudorange and measured pseudorange. The reference pseudorange is computed from the reference position to a satellite. The measurement error covariance is determined as function of the difference only if the measured pseudorange is greater than the reference pseudorange. The GNSS receiver also determines measurement error covariance as function of one or more of correlation peak shape, difference, the correlation peak shape, a received signal to noise ratio and a tracking loop error.

  • Publication number: 20140161202
    Abstract: A peak-to-average ratio (PAR) of a signal is reduced by clipping the signal at a threshold level and replacing desired frequency tones of the clipped signal with set of frequency tones of the signal. In one embodiment, the PAR of a signal is reduced by adding a peak cancellation signal to the received signal. The peak cancellation signal is generated by clipping the received signal at a threshold level and generating a difference signal by subtracting the received signal from the clipped signal. The peak cancellation signal thus generated is scaled by a scaling factor and added to the received signal to reduce the PAR of the received signal. The scaling factor is adjusted to maintain the desired quality of the received signal. In one embodiment, the PAR of an orthogonal frequency division multiplexed (OFDM) signal may be reduced.
