Abstract: An integrated circuit includes first and second bus terminals, a pass-gate transistor, first and rising time accelerator (RTA) control circuits, and first and second falling time accelerator (FTA) control circuits. The pass-gate transistor couples between the first and second bus terminals. The first RTA control circuit couples to the first bus terminal, detects a rising edge on the first bus terminal, and accelerates the rising edge on the first bus terminal. The first FTA control circuit couples to the first bus terminal, detects a falling edge on the first bus terminal having a slope below a threshold, and accelerates the falling edge on the first bus terminal. The second RTA and FTA control circuits function similar to the first RTA and FTA control circuits but with respect to the second bus terminal.

Abstract: A multi-standard indoor mobile radio access network having a centralized device is provided. In one embodiment of the present invention, once an emergency (e.g., 911, etc.) call has been place by a wireless device, an application operating on the device transmits a notification signal to the centralized device (e.g., via a radio head, etc.). In response thereto, the centralized device transmits location information of the wireless device to an emergency responder via a wireless service provider, where the location information is transmitted separately from the emergency call itself.

Abstract: In an actuator driver array, each actuator driver includes a transition stage to initiate a state change of a driver output signal, a static stage to maintain the state change, and an isolation resistor to couple the driver output signal to an output node of the actuator driver during a static mode.

Abstract: A system and method for using at least location information to facilitate a transaction is provided. In one embodiment of the present invention, a mobile application operating on a mobile device is used to determine a location of the mobile device. Location information is then provided to a host device, where it is used to identify a second party (e.g., a store at the location, etc.). Information on the second party (e.g., store name, etc.) and acts of commerce (e.g., goods and services) offered by the second party is then provided to the mobile application. A first party can then interact with the mobile application to select or confirm an act of commerce that they would like to purchase. The host device then charges a payment method linked to the first party's account, and receipts of the purchase are provided to the mobile application and a merchant device.

In response thereto, the centralized device transmit location information of the wireless device to an emergency responder. The centralized device also transmits a “ping” to the wireless device during predetermined periods of time in order to keep the application open and/or installed on the wireless device.

Abstract: A dual-mode driver includes a transition stage and a static stage. The transition stage switches a bias voltage or an RF ground potential to an output pad to change the state of an RF actuator device connected at the output pad. After waiting a predetermined period of time for the RF actuator device to change state, the transition stage of the driver is disabled. A high-side or low-side static stage transistor maintains the driver output state through an isolation resistor. The isolation resistor and a capacitor formed at the driver output pad form an RC low-pass filter to block spurious noise generated at the driver. The RC filter also blocks RF energy that might otherwise enter the actuator driver from the actuator. Some embodiments also include a second RC filter located proximate to the output pad to prevent RF energy generated in the RF actuator from entering the driver.

Abstract: A method, system, apparatus and media are directed to managing trading of financial instruments with a clearinghouse as a counter-party to trades. A plurality of inputs that includes trade data for trades executed using the computer system is received. A discount curve for projected prices of a swap contract over time based on the received plurality of inputs is determined in real-time. A swap contract price is valued based on the determined discount curve. A margin requirement is determined for a user who wishes to trade or hold a position in the swap contract in the user's account based on the swap contract price. Data about a trade of the swap contract that is executed within the computer system is incorporated into the trade data used for determining the discount curve to provide a feedback loop into the real-time determination of the discount curve.
