| 20090256608 | Low leakage data retention flip flop - A disclosed embodiment is a low leakage data retention flip flop comprising a master circuit for retaining data during sleep mode, wherein the master circuit is configured to receive a reduced supply voltage during the sleep mode. The flip flop includes a slave circuit having low threshold voltage transistors, where the slave circuit is turned off during the sleep mode. In various embodiments, the master circuit might utilize high threshold voltage, standard threshold voltage, or low threshold voltage transistors. Similarly, the slave circuit might utilize high threshold voltage, standard threshold voltage, or low threshold voltage transistors. To begin the sleep mode, the master circuit receives a reduced supply voltage and the slave circuit is coupled to ground and is thus turned off. During the sleep mode, the slave circuit experiences virtually no leakage current, and the master circuit experiences a reduced leakage current. | 10-15-2009 |
| 20100001774 | Data retention flip flop for low power applications - A disclosed embodiment is a data retention flip flop comprising master and slave circuits that are configured to be turned off when a single sleep mode signal is activated. The disclosed embodiment also comprises an always-on balloon circuit coupled to the master circuit, where the always-on balloon circuit includes a common sub-circuit shared with the master circuit. The master circuit writes into the always-on balloon circuit when the single sleep mode signal is activated, and the master circuit reads from the always-on balloon circuit when the single sleep mode signal is deactivated. The always-on balloon circuits comprises high threshold voltage transistors, while the slave circuit comprises low threshold voltage transistors. The master and slave circuits have no leakage current, or substantially no leakage current, after the single sleep mode signal is activated. | 01-07-2010 |

| 20080244539 | ENABLING ANALYSIS OF SOFTWARE SOURCE CODE - A source code clarification system is described. In various embodiments, the source code clarification system receives clarified source code and transforms the clarified source code into standard source code or object code that implements asynchronous components. The standard software source code can contain expressions for enabling asynchronous communications. The clarified code can be software source code that is expressed in an imperative language and is capable of static analysis. The clarified source code can contain a coordination primitive that encapsulates interactions between asynchronous components. By using the coordination primitives and events, the clarified source code can express interactions between asynchronous components so that the clarified source code is easier for developers to understand and for static analysis tools to analyze. | 10-02-2008 |

| 20110256724 | GAS AND LIQUID INJECTION METHODS AND APPARATUS - A liquid injection system for a processing chamber includes a liquid injector that receives a liquid from a liquid supply and that selectively pulses the liquid into a conduit. A control module selects a number of pulses and a pulse width of the liquid injector. A gas supply supplies gas into the conduit. A sensor senses at least one of a first temperature and a first pressure in the conduit and that generates at least one of a first temperature signal and a first pressure signal, respectively. The control module confirms that the selected number of pulses occur based on the at least one of the first temperature signal and the first pressure signal. | 10-20-2011 |
| 20110256726 | PLASMA ACTIVATED CONFORMAL FILM DEPOSITION - Methods of depositing a film on a substrate surface include surface mediated reactions in which a film is grown over one or more cycles of reactant adsorption and reaction. In one aspect, the method is characterized by the following operations: (a) exposing the substrate surface to a first reactant in vapor phase under conditions allowing the first reactant to adsorb onto the substrate surface; (b) exposing the substrate surface to a second reactant in vapor phase while the first reactant is adsorbed on the substrate surface; and (c) exposing the substrate surface to plasma to drive a reaction between the first and second reactants adsorbed on the substrate surface to form the film. | 10-20-2011 |

| 20120059696 | SYSTEMS AND METHODS FOR PROVIDING ADVERTISEMENTS TO USER DEVICES USING AN ADVERTISEMENT GATEWAY - An advertisement gateway that provides an interface for multiple user devices and multiple advertisement sources to communicate is presented. The advertisement gateway is capable of translating advertisement requests from a user device in a particular format into another format that is compatible with an advertisement source. Conversely, the advertisement gateway can translate advertisement responses from an advertisement source in a particular format into another format that is compatible with the requesting device. In this manner, the advertisers only have to develop an advertisement using a single protocol and format (i.e., the protocol to communicate with the advertisement source) and still be able to provide their advertisements to a wide variety of user devices. | 03-08-2012 |
