Appl. No.:

10/201103

Inventors:

Milap V. Majmundar - Austin TX, US
David R. Wolter - Austin TX, US

Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04M003/00
H04B007/00
G08B005/22
G06F015/16

US Classification:

455419, 455466, 455512, 340 729, 709206

Abstract:

A central host performs an automated method of updating multiple remote devices. In one embodiment, the host recognizes a predetermined download time and, in advance of the download time, transmits a calendar update to multiple remote devices. The calendar update includes the download time, and the remote devices may utilize the download time to set calendar reminders for entering an active state. Within a short time after reaching the download time, the host pushes download data to the remote devices by broadcasting the download data. In one aspect, the host may receive message acknowledgements from remote devices in response to a first calendar update, and the host may automatically transmit additional calendar updates to any remote devices that did not receive the first calendar update. Additional embodiments involve related methods and the terminal devices that receive the updates.

Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04D 1/00
H04L 27/06

US Classification:

375341

Abstract:

A desired signal and at least one interfering signal are joint demodulated with a Viterbi equalizer having an adaptive total number of states. The total number of states is based on channel impulse response (CIR) coefficients associated with the desired signal and the at least one interfering signal.

International Classification:

G06Q 30/00

US Classification:

705 26

Abstract:

One or more content providers push data related to: movies, movie products, digital movie content over a network (e. g. , a LAN, a WAN, the Internet, or a wireless network) onto an information filling station which, in turn, wirelessly transacts (over a network based on the 802. 11protocol) and transmits any requested data to a portable computer-based device (e. g. , laptop, a pen-based computer device, a PDA, a wireless phone, or a pager). The portable device performs financial transactions for: purchasing movie tickets (directly or via auctions), downloading digital entertainment content of interest (e. g. , copy of a movie of interest, copy of a movie identified based on a pre-stored profile, copy of soundtrack of a movie of interest), or movie related products. Any purchased digital content is either transferred wirelessly onto the portable device or, optionally, sent on a storage medium to a physical address associated with the profile.
