US Classification:

707728, 386124, 386E05003, 707E17014

Abstract:

A method and apparatus for an adaptive search user interface is provided. An interface is provided that returns search results upon receiving each alphanumeric character of a search query term. Correlations of prefixes of alphanumeric characters and search results selected from previous searches are stored in a correlation matrix. Based upon the correlations in the correlation matrix, relevance rankings for search results with respect to the prefixes of alphanumeric characters are updated. Search results may be grouped based upon one or more common traits. Relevance rankings are also updated based upon the rate of change of selections recorded for a search result.

International Classification:

H04N 21/462

US Classification:

725 49, 725 39

Abstract:

A multimedia program recording schedule manager for DVR systems is described. In a first embodiment, for example, a method implemented by one or more server computing devices, the method comprising: receiving input selecting a particular DVR system; receiving input selecting a particular multimedia program for the particular DVR system to record on a repeat basis; adding the particular multimedia program to a server-side instance of a repeat recording schedule for the particular DVR system; and synchronizing the server-side instance of the repeat recording schedule with another instance of a repeat recording schedule for the particular DVR system resulting in the addition of the particular multimedia program to the other instance of the repeat recording schedule. In one embodiment, the other instance of the repeat recording schedule for the particular DVR system is a data component of the particular DVR system.

PLX Technology, Inc. - Sunnyvale CA

International Classification:

H03H 1126

US Classification:

327276

Abstract:

A binary relative delay line device having two delay lines, each of which delays, during a time interval, an input signal by a substantially equal amount of time. Each delay line requires a settling time before it is selected during a next time interval. A selection and delay determining circuit is coupled to the two delay lines to select one of them to provide an output signal. A clock is coupled to the selection and delay determining circuit to operate the selection and delay determining circuit at a lower frequency than the frequency of the input signal, the lower frequency being chosen so that any selected delay line has settled before it is selected.
