  • Patent number: 7797187
    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.

  • Patent number: 7663237
    Abstract: A semiconductor structure and a method of forming the same using replacement gate processes are provided. The semiconductor structure includes a butted contact coupling a source/drain region, or a silicide on the source/drain region, of a first transistor and a gate extension. The semiconductor structure further includes a contact pad over the source/drain region of the first transistor and electrically coupled to the source/drain region. The addition of the contact pad reduces the contact resistance and the possibility that an open circuit is formed between the butted contact and the source/drain region. The contact pad preferably has a top surface substantially leveled with a top surface of the gate extension.

  • Publication number: 20090180638
    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.

  • Publication number: 20060082391
    Abstract: Methods and systems that use a simple hardware circuit and/or digital logic solution to identify and remove both positive and negative glitches from a signal. For this hardware circuit and/or digital logic solution, a glitch is referred to as an unwanted pulse with a width less than a specified duration, and is generally caused by noise or improper operation by other devices. A positive glitch occurs when the input signal has been logic low for some time, while a negative glitch occurs when the input signal has been logic high for some time. In one embodiment, the hardware circuit and/or digital logic solution removes noises from signals transmitted between a digital circuit and its switches and/or remote sensors, such as switches of keyboards and mice.
