  • Patent number: 8258751
    Abstract: Methods, systems, and apparatuses for determining battery state of health are provided. A battery that is substantially uncharged is charged with a substantially constant charge current. A time duration of the charging of the battery with the substantially constant charge current is determined. A state of health of the battery is estimated based upon the determined time duration and the constant charge current. The state of health of the battery may be calculated by multiplying the determined time duration with a value of the constant charge current to determine a total accumulated charge, and applying a predetermined factor to the accumulated charge to determine the state of health. The predetermined factor is a fixed percentage of the total charge capacity of the battery that corresponds to the battery type.

  • Patent number: 8259787
    Abstract: A method and a system for providing an input signal from a multiple decision feedback equalizer to a decoder based on a tail value and a subset of coefficient values received from a decision-feedback equalizer. A set of pre-computed values based on the subset of coefficient values is generated. Each of the pre-computed values is combined with the tail value to generate a tentative sample. One of the tentative samples is selected as the input signal to the decoder. In one aspect of the system, tentative samples are saturated and then stored in a set of registers before being outputted to a multiplexer which selects one of the tentative samples as the input signal to the decoder.

  • Publication number: 20120219193
    Abstract: A system and method for retaining, associating, and reloading a user's preferences in a video game system without requiring active participation from the user is provided. The system may include an object control mechanism for receiving a passive indication from the user to perform a fingerprint scan of the user's fingertip. A fingerprint scanner may be coupled to the object control mechanism for transparently performing the fingerprint scan to generate identifying data for the user. If the identifying data for the user matches identifying data for a preexisting user, then preferences associated with the preexisting user may be reloaded. If the identifying data for the user does not match identifying data for a preexisting user, then preferences of the user may retained and associated with the user's identifying data.

  • Publication number: 20120220244
    Abstract: Wideband-Code Division Multiple Access (W-CDMA) transmit architecture. A baseband digital processing module operates cooperatively with an analog signal processing module to effectuate highly adjustable and highly accurate gain adjustment in accordance with transmitter processing within a communication device. The gain adjustment and/or gain control is partitioned between the digital and analog domains by employing two cooperatively operating digital and analog modules, respectively. Gain adjustment in the analog domain is performed in a relatively more coarse fashion that in the digital domain. If desired, gain adjustment in each of the analog and digital domains is performed across a range of discrete steps. The discrete steps in the analog domain are larger than the discrete steps in the digital domain. Also, the discrete steps in the digital domain may be interposed between two successive discrete steps in the analog domain.

  • Publication number: 20120221964
    Abstract: A method for soliciting opinion feedback in a computer-based social network in which the computer-based social network is populated by a set of users defined by social profiles indicating shared interests with an individual. The method includes displaying, in substantially real-time, a mirrored-representation of an individual based upon a captured digital image of the individual. The individual identifies an item of a plurality of items, wherein the mirrored-representation mimics a motion gesture of the individual to identify the item. The individual adorns the mirrored-representation with the identified item of the plurality of items, uploads the adorned mirrored-representation to the computer-based social network. The individual receives, in response, opinion feedback relating to the adorned mirrored-representation from at least a subset of the set of users.

  • Publication number: 20120218995
    Abstract: A system and method for allowing flexible associations between PHY devices and MAC devices in a point-to-multipoint communications system, such that a given upstream channel is not deterministically bound to a particular MAC device. An upstream MAC device may connect to a varying number of PHY devices depending on configured PHY capacity. Upstream service flows are intact by noting Service identifiers (SIDs) of each burst received at a PHY device, A burst is then directed via a switching infrastructure to the appropriate MAC on the basis of the SID.

  • Publication number: 20120218980
    Abstract: Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.
