20140120292 | COLOR-CHANGING SEALANT - A sealing element that utilizes cohesive peeling to visually indicate when a sealing element has been opened. The peel layer and bulk layer can be coupled together and contain coloring agents which are complementary colors that together make up a secondary color. Alternatively, the peel layer can be coupled to a first bulk layer and the first bulk layer coupled to a second bulk layer. The colors of the coloring agents applied to the peel layer and first bulk layer together do not make up a secondary color, and the colors of the coloring agents of the second bulk layer and the first bulk layer together do not make up a secondary color. | 05-01-2014 |

20110169579 | METHOD AND APPARATUS FOR INCREASING DISTRIBUTION OF JITTER WITHIN A RANDOM NUMBER GENERATOR - A random number generator comprises a first high frequency (HF) oscillator, a second low frequency (LF) oscillator, a delay buffer, a multiplexer, and a sampling circuit. The HF oscillator generates a high frequency oscillating signal. The LF oscillator generates a low frequency oscillating signal. The multiplexer selects from the LF oscillating signal and one or more delayed version of the LF oscillating signal to generate a third oscillating signal. The third oscillating signal is then used to sample the HF oscillating signal to output a random bit stream. In one preferred embodiment, the random bit stream is feedback to the multiplexer to make randomized selection. As a result, the original jitter distribution of the LF oscillating signal is increased to a larger jitter distribution of the third oscillating signal to increase the random behavior of the output bit stream. | 07-14-2011 |
20110169580 | INVERTING GATE WITH MAXIMIZED THERMAL NOISE IN RANDOM NUMBER GENERTION - A random number generator comprises a first high frequency (HF) oscillator, a second low frequency (LF) oscillator, and a sampling circuit. The HF oscillator generates a high frequency oscillating signal. The LF oscillator generates a low frequency oscillating signal. The LF oscillating signal is used to sample the HF oscillating signal to generate a sequence of random bits. In one preferred embodiment, the LF oscillator comprises a plurality of stages of inverters, and each inverter comprises a number of series-stacked minimum length transistors. The LF oscillating signal has a jitter distribution due to thermal noise present in each transistor of the LF oscillator. By series stacking a number of minimum length transistors in each inverter, the overall thermal noise in the LF oscillator is maximized to increase the jitter distribution of the LF oscillating signal and thereby increase the random behavior of the sequence of random bits. | 07-14-2011 |

20080307244 | Method of and Apparatus for Reducing Power Consumption within an Integrated Circuit - An integrated circuit comprising a plurality of processing cores, characterised by comprising electrically controllable switches for controlling the supply of power to one or more of the processing cores, a memory for saving state data from at least one of the processing cores and a controller adapted to control the supply of power to one or more of the processing cores such that processing cores can be de-powered. | 12-11-2008 |
20160124045 | MEASUREMENTS CIRCUITRY AND METHOD FOR GENERATING AN OSCILLATING OUTPUT SIGNAL USED TO DERIVE TIMING INFORMATION - A measurement circuit and method is provided for generating an oscillating output signal used to derive timing information. The measurement circuit includes a ring oscillator having a plurality of unit cells, where each unit cell comprises at least a storage element whose output signal is used to determine a clock input signal for an adjacent unit cell within the ring oscillator. Control circuitry performs a control operation to control either a set function or a reset function of the storage element in each of the unit cells, in dependence on set or reset signals input to the control circuitry. Oscillation initiation circuitry is used to assert a clock input signal to the storage element in a first unit cell in order to initiate generation of the oscillating output signal, and the control circuitry then performs the control operation in order to control a value of the output signal of the storage element in each unit cell so as to cause the oscillating output signal to be maintained. Such an approach provides a particularly simple and efficient mechanism for deriving timing information for various circuit blocks that include a storage element. | 05-05-2016 |

20160126939 | SYNCHRONISER FLIP-FLOP - A synchroniser flip-flop is provided, which is able to better respond to input values that are not provided for the necessary setup or hold times. The flip-flop includes a latch that includes inverter circuitry for producing a first signal and a signal in dependence on a value of an input signal at a node. A clocked inverter includes a first switch that is connected between a first reference voltage supply and an intermediate node and a second switch, which is connected between the intermediate node and a second reference voltage supply. The first switch is controlled by the first signal and the second switch is controlled by the second signal to produce an output signal at the intermediate node. | 05-05-2016 |

20110060810 | APPLICATION SERVER PROVIDING PERSONALIZED VOICE ENABLED WEB APPLICATION SERVICES USING EXTENSIBLE MARKUP LANGUAGE DOCUMENTS - A unified web-based voice messaging system provides voice application control between a web browser and an application server via an hypertext transport protocol (HTTP) connection on an Internet Protocol (IP) network. The application server, configured for executing a voice application defined by XML documents, selects an XML document for execution of a corresponding voice application operation based on a determined presence of a user-specific XML document that specifies the corresponding voice application operation. The application server, upon receiving a voice application operation request from a browser serving a user, determines whether a personalized, user specific XML document exists for the user and for the corresponding voice application operation. If the application server determines the presence of the personalized XML document for a user-specific execution of the corresponding voice application operation, the application server dynamically generates a personalized HTML page having media content and control tags for personalized execution of the voice application operation; however if the application server determines an absence of the personalized XML document for the user-specific execution of the corresponding voice application operation, the application server dynamically generates a generic HTML page for generic execution of the voice application operation. Hence, a user can personalize any number of voice application operations, enabling a web-based voice application to be completely customized or merely partially customized. | 03-10-2011 |
