  • Publication number: 20090221252
    Abstract: System and methodologies for amplifier gain control in a communication system are provided herein. By leveraging similarities between the distribution of received signal samples in an MB-OFDM system and a Gaussian distribution, various algorithms described herein can be utilized to perform fast and low-complexity amplifier gain tuning. Received signal strength indication information corresponding to analog signal samples and/or digital signal samples obtained from an analog to digital converter are analyzed to obtain a signal energy distribution. The obtained signal energy distribution is then compared to a reference Gaussian distribution to adaptively tune an associated amplifier gain.

  • Patent number: 7548851
    Abstract: A musical jukebox is disclosed which provides for: fast archiving of songs; a flexible user interface; easy and convenient entry of, access to and/or display of data relating to songs archived by the jukebox; easy and convenient search and locate capabilities for locating, reviewing, retrieving and/or playing songs stored in the jukebox; and low cost relative to the functionality, features, conveniences and user-friendliness provided by the jukebox. Fast of flush archiving of songs (as well as other data and signals) is accomplished by first saving sets of data without compression, which allows the data to be entered quickly, and then, compressing later at an appropriate time. A unique MP3 bit allocation encoding scheme is used to compress data. A unique memory allocation supports fast data archiving. The user interface employs two-way communication between a remote control and the jukebox. A searchable song database is structured to enable very fast searching by music category, and also by title and artist.

  • Publication number: 20090109953
    Abstract: System and methodologies for timing synchronization in a wireless communication system are provided herein. The provided systems and methodologies can utilize various timing synchronization algorithms and an associated state machine to reduce the down time of a wireless communication system due to the presence of simultaneously operating piconets (SOP) and/or other factors. Frequency band finger pattern detection techniques are additionally described that can reduce boundary mismatch rates for wireless receivers. In one example, by making use of the fact that time frequency codes (TFCs) possess unique frequency hopping patterns, system down time can be reduced and OFDM boundary matching can be enhanced to allow a receiver to obtain correct timing information even for communication channels having a very low SINR.

  • Publication number: 20080261572
    Abstract: A mobile device facilitates customized services for its user. For example, a mobile device can record information about a user using multiple inputs (e.g., sensors, GPS, camera, etc.). The information recorded creates a log of activities and interests of the user. One or more parts of the log are published and the user receives additional information based on the published information, such as other nearby people with similar interests or coupons. Other services of the mobile device can include biometric (e.g., facial) recognition of people, voting/polling, and language translation. The services available on a mobile device can be pre-configured so that the user can use the various services out of the box.

  • Publication number: 20080246734
    Abstract: Body-based sensors are used to interact with one or more mobile devices. This interaction can be an alternative to or a supplement to traditional input methods on mobile devices. In order to facilitate everyday use, sensors can be hidden in jewelry or other fashion accessories normally worn by a user and wirelessly coupled to the mobile devices. When certain body movement is detected, a mobile device can automatically initiate one or more processes that perform various actions, such as actions on that mobile device or actions on communicatively coupled devices. The body movements can be user-defined so that a user can customize his interaction with the mobile device to meet the user's particular needs. The sensor array can also be adapted to turn on or off depending on the current environment.
