US Patent:

6389149, May 14, 2002

Filed:

Dec 31, 1997

Appl. No.:

09/002134

Inventors:

Andrew Liu - Portland OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06K 900

US Classification:

382100, 345501, 345502

Abstract:

An improved method and apparatus for processing video data is provided. A video subsystem generates first and second fields of video image data. First fields of video image data need not be sent over a common bus, but instead can be sent over a port connection (such as the Zoom Video port connection) to the graphics subsystem for display. Second fields of video image data can be sent over the bus to a processor subsystem for compression and eventual transmission to a remote user via a modem or the like. Because the video subsystem generates first and second fields of video image data (e. g. , an even and odd field for each frame), the video image data for local display need not be sent over the bus to the processor subsystem and need not be converted by the processor subsystem. This results in a savings in bus usage and processor execution needs.

Appl. No.:

09/469659

Inventors:

Andrew S. Liu - Portland OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 1300

US Classification:

710316, 710305, 710 62, 710100

Abstract:

A method and apparatus for allowing multiple electronic systems to share a Universal Serial Bus (USB) device is disclosed. In one embodiment, the electronic systems and the USB device are connected to a switcher. The switcher performs bus enumeration to acquire USB device information and presents a number of images of the acquired USB device information to the electronic systems. The switcher also maintains logical links between the connected electronic systems and the USB device. Lastly, the switcher selects one of the connected electronic systems to communicate USB data packets with the USB device.

International Classification:

G10L 2100

US Classification:

704500, 369 85

Abstract:

The present invention discloses method and system of encoding audio information (e. g. , music, speech, etc. ) from an analog medium (e. g. , vinyl recordings, cassette tapes, etc. ) into a compressed, track-oriented, digital format using attribute information and silence detection. The invention generates an analog audio signal by reproducing the audio information recorded on the analog medium, which is recorded on a plurality of discrete analog tracks. The analog audio signal is then sampled to generate a digital audio file (i. e. , WAV file). The digital audio file is filtered to correct defects and then separated into a plurality of discrete digital audio tracks. Attribute information, such as track length, is accessed and confirmed by silence detection techniques in order to provide separation. This separation is accomplished such that each of the discrete digital audio tracks contains audio information corresponding to each of the discrete analog tracks, and are thus, arranged in a track-oriented digital format. The discrete digital audio tracks are then compressed (e. g.

Abstract:

The present invention provides of using multimeric MHC class II/peptide complexes. In one aspect, methods provided for identifying MHC class II-restricted immune epitopes of a predetermined polypeptide antigen. Methods for identifying an immunostimulatory epitope for a predetermined polypeptide antigen are provided. In a related aspect, methods for screening a therapeutic polypeptide agent for an MHC class II epitope are provided. In other aspects, methods for modulating T cells and for determining or monitoring an MHC class II-restricted immune status of a patient are also provided.

International Classification:

G06F017/60

US Classification:

705/014000, 705/010000

Abstract:

A system and method for generating real-time promotions to a visitor of an electronic commerce (e-commerce) World Wide website to increase the likelihood of purchase on the website by the visitor. The system and method receive and store clickstream data provided by the visitor, and calculate the probability that the visitor will leave the website or will make a purchase on the website based upon this clickstream data. The system and method then utilize the calculated probabilities, as well as the frequency of visits to the website by the visitor, and the time of the visit to the website, to decide whether or not real-time promotions should be generated on the website. If it is decided that promotions should be generated, then the system and method automatically calculate what promotions to send, when to send them, and how to send them. The system and method enable e-commerce owners and managers to better direct their promotions, enable promotions to be tailored to the visitors' display preferences, and generate the right promotion at the right time and the right place. Furthermore, the system and method become increasingly effective and refined with more visitors to the e-commerce website, providing the e-commerce website owner or manager with a better understanding of his or her customers, increased revenue, and greater marketing efficiency. The visitors to the e-commerce website, in turn, receive better service, information and value.
