  • Patent number: 8111788
    Abstract: An apparatus for estimating and correcting baseband frequency error in a receiver is disclosed. An equalizer performs equalization on a sample data stream and generates filter tap values based on the equalization. An estimated frequency error signal is generated based on at least one of the filter tap values. A rotating phasor is generated based on the estimated frequency error signal. The rotating phasor signal is multiplied with the sample data stream to correct the frequency of the sample data stream. Alternatively, a channel estimator performs channel estimation and generates Rake receive finger weights based on at least one of the finger weights. An estimated frequency error signal is generated based on at least one of the finger weights.

  • Patent number: 8111495
    Abstract: A low forward voltage drop transient voltage suppressor utilizes a low-reverse-voltage-rated PN diode electrically connected in parallel to a high-reverse-voltage-rated Schottky rectifier in a single integrated circuit device. The transient voltage suppressor is ideally suited to fix the problem of high forward voltage drop of PN diodes and high leakage of low reverse breakdown of Schottky rectifiers. The low-reverse-voltage PN rectifier can be fabricated through methods such as 1) double layers of epi (with higher concentration layer epi in the bottom) or 2) punch through design of PN diode by base with compression.

  • Patent number: 8107906
    Abstract: Methods and apparatus for implementing a wireless communication transceiver having receive path performance diversity. The transceiver implements a plurality of signal paths that can be configured as space diversity receive paths. Each of the plurality of signal paths includes a distinct RF filter. Each RF filter can be configured to provide a distinct frequency response, and in particular, a distinct jammer rejection profile. One of the RF filters can be configured to provide substantially no in-band jammer rejection. Each additional distinct RF filter can be configured to reject at least one distinct in-band jammer frequency or band of frequencies. A diversity receiver coherently combines the path performance diverse signals from each filter output. A transmitter can time division duplex transmit communications over at least a subset of the signal paths and their associated RF filters.

  • Patent number: 8104978
    Abstract: A wedge-type mechanical optical fiber splice is provided in the present invention. The splice comprises a housing, a V-grooved block, a pushing block, and a first wedge. The housing is a hollow block, and has two openings for guiding optical fiber at two opposite sides. The V-grooved block, so called a first block, is a long strip block having a V-shaped groove on its surface. The pushing block, so called a second block, confronts to the V-grooved block. The first wedge is a wedged-type block. The second block is moved toward the first block or the first block is moved toward the second block by pushing down the first wedge, so that two optical fibers are aligned and secured in the V groove.

  • Patent number: 8108748
    Abstract: The subject matter disclosed herein provides an outer coding framework that, in some implementations, provides frequency diversity to outer codewords that are mapped to modulation symbols. In one aspect, there is provided a method. The method may include inserting a received packet into a frame. Moreover, an outer code may be used to encode the frame. Furthermore, the values read from a column of the frame may be inserted into a link-layer packet. In addition, the column may be shuffled by moving the values of the column based on an offset. The link-layer packet may also be provided to enable an inner code to encode the link-layer packet before transmission. Related systems, apparatus, methods, and/or articles are also described.

  • Patent number: 8104439
    Abstract: Traditional camshaft adjusters are connected to a lubricant circuit of an internal combustion engine. Lubricant flows which are too large flood the drive of the camshaft adjuster, which leads to needless churning losses in the drive and needless losses of the pump capacity of the lubricant for other structural components of the internal combustion engine. According to the invention, a flow element (59), which includes a throttle element or screen in the flow channel (26), is used. According to another embodiment of the invention, the throttle element or screen can be used in various ways.

  • Patent number: 8104462
    Abstract: The present invention is directed to a ball feed mechanism and associated method for use in a paintball loader. The ball feed mechanism includes a feeder which conveys or impels balls toward a feed neck, and a drive member which is concentric with the feeder. The feeder is coupled to the drive member. An electric motor is used to rotate the drive member which in turn causes the feeder to rotate. The feed mechanism includes sensors which detect the motion of the feeder and the drive member. A controller determines the position of the feeder relative to the drive member and actuates a motor when necessary.

  • Patent number: 8107393
    Abstract: A method and apparatus for estimating a signal-to-interference ratio (SIR) are disclosed. A received signal includes signal energy on multiple basis functions. Desired signal energy in the received signal is transformed onto a first basis function with constant polarity. The desired signal energy is estimated by coherently averaging signal energy on the first basis function. A noise power is estimated by averaging signal energy on each basis function other than the first basis function and accumulating the averaged signal energy from the basis function other than the first basis function and scaling the accumulated signal energy to account for a noise estimate from the first basis function. An SIR is estimated by dividing the desired signal energy by the noise power.

  • Patent number: 8108505
    Abstract: In a method for controlling channel access in wireless communications, an admitted time value is calculated for each access category in a station. The admitted time value is a maximum amount of medium time the station can use in a time period. A used time value is calculated for each access category in the station. The used time value is an amount of medium time used by the station. A determination is made whether the used time value is less than the admitted time value. If the used time value is less than the admitted time value, a frame with enhanced distributed channel access (EDCA) parameters is transmitted. If the used time value is not less than the admitted time value, a frame without the EDCA parameters is transmitted.
