US Classification:

705 10, 705400, 705 26, 705 141, 705 7, 705 5

Abstract:

A method and system for protecting prices is provided. The price protection system increases consumer confidence when making purchases by reducing the risk associated with fluctuating prices. The price protection system receives a purchase specification from a consumer. Next, the price protection system determines the risk that the prices of items matching the purchase specification will change and reports a protected price to the consumer that represents the price that the price protection system will protect based on the determined risk for a protection period. Finally, the price protection system receives a request from the consumer to purchase protection of the protected price.

Assignee:

Farecast, Inc. - Seattle WA

International Classification:

G06Q 10/00

US Classification:

705 5, 705 6

Abstract:

A method and system is provided for making price-related predictions of items based on training a classifier using historical information including pricing information for the items and labels relating to the price-related information that are generated automatically from the historical information. A prediction system provides price-related predictions for airline tickets. The prediction system collects flight information for flights on a daily basis. The prediction system generates training data to train a classifier to make the price-related predictions using the flight information. After training the classifier, the prediction system then can make the price-related predictions for a trip.

Appl. No.:

12/013291

Inventors:

David Hsu - Cupertino CA, US
John Walley - Ladera Ranch CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04R 5/02

US Classification:

381311, 381 74

Abstract:

Methods and systems for wireless communication are disclosed and may include controlling a loading and/or a charging of a battery source in each earpiece of the wireless stereo headset. The loading control may include switching between the battery sources powering the headset. A remaining power level may be monitored for each of the battery sources. Both earpieces in the headset may be powered utilizing one or both of the battery sources. One of the earpieces in the headset may be powered utilizing one of the battery sources. A total usage time may be stored for each of the battery sources. The loading and charging of the battery sources may be controlled by equalizing the total usage time for each of the battery sources. The earpieces in the headset may be coupled via a tether line, or may be coupled wirelessly.

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04R 25/00

US Classification:

381384, 381370

Abstract:

Methods and systems for wireless headset instant on capability during battery charging are disclosed and may include powering a wireless headset so that it may be operable to transmit/receive wireless signals during charging. The headset may be powered via an external charger and may be coupled to the headset via a USB link. The headset may be powered via one or more internal batteries, and may be independent of a power level of the batteries within the headset. RF and baseband circuitry may be powered for transmitting/receiving wireless signals during charging. The headset may utilize USB power management, and may manage discharge of power from a plurality of internal batteries. The batteries may be decoupled from circuits that enable transmitting/receiving wireless signals during charging. The headset may be powered via the charging device so that the headset may be operable to generate output audio signals during charging.

International Classification:

G06Q 10/00

US Classification:

705 711

Abstract:

An electronic catalog system monitors browsing actions of users to generate user activity data. A data mining component analyzes the user activity data to generate conditional probability data that is presented to users contextually to assist users in selecting items from the electronic catalog. The conditional probability data reflects the frequencies with which users that have performed specific actions, such as viewing a particular item, set of items or web page, or conducting a specific search, have thereafter acquired specific items from the catalog. For example, in one embodiment, when a user selects a first item for viewing in the catalog, the user is notified, for at least one second item, of a frequency with which users who have viewed the first item and then made a purchase have acquired the second item.
