20110119257 | Method and System for Enterprise Search Navigation - A method can include receiving a search request from a user interface (UI), selecting one or more repositories in response to the search request, and displaying, on a display device, search results corresponding to the selected repositories. The selected repositories are a subset of a plurality of available repositories, as specified by an administrator. By selecting or de-selecting the available repositories, a user can define or refine a search of the available repositories. In various implementations, the method includes interface elements that assist a user in previewing revised search results based on revised selections of repositories, and/or selections of subcategories of information available in one or more of the repositories. | 05-19-2011 |

20160132309 | Efficient Framework for Deploying Middleware Services - A system, method, and computer program product provide computerized services to multiple enterprises. A developer creates each service according to a template, which includes both core functionality common to all services, and individualized functionality specific to the service. The developer either deactivates, or activates and configures, each function in the core based on a service level agreement with the particular enterprise for which the service was created. The template provides a wide variety of core functions, including dynamic data transformation, auditing, logging, exception handling, performance monitoring, service availability, reporting, security, and dynamic reconfiguring. After the service is deployed, it begins to report performance and usage data to a monitoring system. Based on these data, the system calculates an amount to charge the enterprise for use of the given service. | 05-12-2016 |

20120242404 | ADC Preamplifier and the Multistage Auto-Zero Technique - Embodiments of the present invention provide a sample and hold amplifier that provides a preamplifier with a multi-stage zeroing architecture. The multi-stage architecture reduces effects of parasitic capacitance exponentially over prior attempts, which yields increased accuracy. | 09-27-2012 |
20140203957 | CONTINUOUS TIME INPUT STAGE - A continuous time input stage including a first digital-to-analog converter (DAC) including a first DAC code input, a second DAC including a second DAC code input, a first set of switches coupled to the output of the first DAC, a second set of switches coupled to the output of the second DAC, and an amplifier configured to receive the output of either the first DAC or the second DAC. | 07-24-2014 |
20150061908 | LINEAR AND DC-ACCURATE FRONTEND DAC AND INPUT STRUCTURE - A digital-to-analog (DAC) element may include a plurality of switches arranged to form two circuit branches between a current source and a first and a second outputs. The first circuit branch may include two switches defining parallel current paths between the current source and the first output terminal. The second circuit branch may include two switches defining parallel current paths between the current source and the second output terminal. A control circuit, responsive to an input signal that selects one of the circuit branches, may provide control signals to close one of switches in the selected circuit branch in a first portion of a clock cycle and to close the other of the switches in the selected circuit branch in a second portion of the clock cycle. | 03-05-2015 |
20150102949 | METHOD AND APPARATUS FOR REDUCING CAPACITOR INDUCED ISI IN DACS - A circuit may include a plurality of primary digital-to-analog (DAC) elements for converting a digital input signal into an analog output signal. A control circuit may control each primary DAC element to switch between a first state and a second state based on the digital input signal to provide the analog output signal at an output representing the digital input signal. A plurality of corrective DAC elements may be coupled in parallel to the plurality of primary DAC elements between the control circuit and the output. The plurality of corrective DAC elements may be controlled to mitigate for intersymbol interference (ISI) due to parasitic capacitance in the primary DAC elements. The plurality of corrective DAC elements may not contribute a direct current to the analog output signal. | 04-16-2015 |
20150270805 | APPARATUS AND METHODS FOR AUTOZERO AMPLIFIERS - Apparatus and methods for autozero amplifiers are provided herein. In certain configurations, an autozero amplifier includes at least three transconductance stages and an autozero timing control circuit configured to control an autozero sequence of the transconductance stages. The autozero timing control circuit can stagger autozeroing of the transconductance stages, such that a relatively small amount of the amplifier's amplification circuitry is connected to or disconnected from the amplifier's signal path at any given time. For example, in certain configurations, when one of the transconductance stages in autozeroed over a particular time interval, the remaining transconductance stages can operate in parallel to provide amplification during that time interval. | 09-24-2015 |

20100164396 | DYNAMIC POWER SAVING PULSE WIDTH MODULATED LED DRIVER CIRCUIT - In accordance with an aspect of the present invention, an LED driving circuit includes a digital-to-analog converter and a driving portion. The circuit is operable to turn off the digital-to-analog converter at times when the driving portion is not providing a high signal. As such the digital-to-analog converter will waste less energy. | 07-01-2010 |
20110088475 | TRANSMITTER WITH INTRINSIC OUTPUT ZEROING - An ultrasound transmitter including intrinsic output zeroing is disclosed herein. A transmitter for generating ultrasound signals includes a first transmitter output driver and a first transmitter input driver. The first transmitter output driver includes an N-type device serially coupled to a P-type device. The first transmitter input driver includes an N-type device serially coupled to a P-type device. An output of the first transmitter input driver is coupled to an input of the first transmitter output driver. The first transmitter output driver drives an output of the transmitter to a first voltage and the first transmitter input driver drives the output of the transmitter to a second voltage while the first transmitter output driver is disabled. | 04-21-2011 |

20110314310 | Low-Power Data Loop Recorder - A system and method are disclosed for capturing pre- and post-event data for random events using minimum power. Real-time data is captured and stored in a continuous loop in a segment of a first memory. Upon detection of a designated event, a second memory is powered-on and post-event data is stored to a segment of the second memory. After a designated data capture window, the second memory is powered-off and real-time data is captured in an unused segment of the first memory. The post-event data may be captured in the unused segment of the first memory and later transferred to the second memory. Auto-address logic monitors and controls the storage and retrieval of pre- and post-event in the first and second memory. An energy management system determines and controls which segments of the first and second memory should be powered-on or kept in the stasis mode to store event data. | 12-22-2011 |
