20150178466 | METHODS FOR AGGREGATE REPORTING OF HEALTH DATA AND DEVICES THEREOF - A method for aggregate reporting of health data includes obtaining health data for a plurality of subjects in a population associated with an entity, the health data comprising diagnostic laboratory testing results, biometric information, or demographic information. Each of the subjects is allocated to one or more dimensions based on the obtained health data and one or more boundary conditions of each of the dimensions, the dimensions corresponding to biometric or demographic information of a specified type. Whether a number of subjects allocated to one of the dimensions is below a threshold is determined. One or more of the boundary conditions for one or more of the dimensions is adjusted when the number of subjects allocated to the one dimension is determined to be below the threshold. The determining and the adjusting are repeated until a number of subjects allocated to the dimensions is not below the threshold. | 06-25-2015 |

20110298688 | RECONFIGURABLE AXIAL-MODE HELICAL ANTENNA - Novel reconfigurable antennas are provided which may be used to accommodate the requirements for wideband multi-standard handheld communication devices. It is shown that using a shape memory alloy spring actuator, the height of a helical antenna and therefore the pitch spacing and angle can be varied. This can in turn tune the far-field radiation pattern and gain of the antenna dynamically to adjust to new operating conditions. The radiation pattern can further be directed using a two-helix array. Finally, a helical antenna embodiment is implemented and measured using a shape memory alloy actuator. Measurement results confirm that while keeping the centre frequency constant, gain tunability can be attained using this structure. | 12-08-2011 |

20140099034 | INTELLIGENT VIDEO THUMBNAIL SELECTION AND GENERATION - In accordance with one embodiment, an intelligent video thumbnail selection and generation tool may select a relevant and visually stimulating image from a video file and generate a thumbnail including the image. The image may be selected by computing a relevancy metric for an image in the file based on one or more selected relevant features, and comparing that relevancy metric with the metric of at least one other image in the file. In another embodiment, a series of images in a video file may be divided into shots. One of the shots may be selected based on a shot relevancy metric and a key image from the shot may be selected as a thumbnail based on a key image relevancy metric, where the shot relevancy metric and the key image relevancy metrics may be computed based on one or more relevant content features. | 04-10-2014 |
20140201180 | Intelligent Supplemental Search Engine Optimization - In accordance with one embodiment, an intelligent supplemental search engine optimization tool may generate keywords relating to content based on additional content collected from one or more data sources, wherein the data sources are selected based on initial input relating to the initial content. Data sources may include one or more third-party resources. A variety of processes may be employed to recommend keywords, including frequency-based and probabilistic-based recommendation processes. | 07-17-2014 |

20090219100 | VOLTAGE-CONTROLLED OSCILLATOR GAIN CALIBRATION FOR TWO-POINT MODULATION IN A PHASE-LOCKED LOOP - A phase-locked loop (PLL) is arranged to receive high-pass data at a first input and low-pass data at a second input. A first digital input is coupled to a primary path through a digital-to-analog converter (DAC) and a second digital input is coupled to a feedback path of the PLL. The controller provides the first input and the second input during a calibration procedure. The controller adjusts first and second control inputs in an attempt to keep the input voltage to a voltage-controlled oscillator (VCO) in the PLL constant while determining the gain of the VCO in Hz/LSB. | 09-03-2009 |
20120170624 | SYSTEMS AND METHODS FOR POWER CONTROL IN A MULTIPLE STANDARD MOBILE TRANSMITTER - A transmitter adjusts a transmitted power level by modifying a control input of a variable gain amplifier. A power amplifier control system includes an envelope extractor, an error extractor, and a feed-forward multiplier. The envelope extractor receives data signal inputs and computes the envelope of the combined signal. The error extractor generates an error signal as a function of the combined signal and the output power generated by the power amplifier. The feed-forward multiplier generates a modified error signal that is responsive to a function of the gain in a feedback path. A corresponding method for controlling a power level is also disclosed. In some embodiments, a transmit chain with a power control loop is used to adjust the transmit signal power applied at an input of a variable gain amplifier. A corresponding method for adjusting the transmit signal power level is also included. | 07-05-2012 |

20120190311 | FREQUENCY GENERATOR AND GAIN CALIBRATION TECHNIQUE FOR TWO-POINT MODULATION IN A PHASE-LOCKED LOOP - A frequency generator includes a phase-locked loop (PLL) and a voltage controlled oscillator (VCO), where the VCO is arranged to receive low-pass data via a first input and high-pass data at a second input. The first input is coupled to a first set of varactors in the VCO. The second input is coupled to a second set of varactors in the VCO. A controller sets the input voltage at the first input and directs a charge pump to operate in a tri-state mode that opens the feedback loop of the PLL. The controller applies different voltages via the second input and measures the change in output frequency. A present gain of the VCO is determined from the ratio of the change in frequency and the change in voltage at the second input and is used to calibrate a portable transceiver. | 07-26-2012 |
20150023450 | APPARATUS AND METHODS FOR POWER CONTROL IN MOBILE COMMUNICATION DEVICES - Apparatus and methods for power control in mobile communication devices are provided. In one aspect, a method for accurately controlling an adjustable power level of a data signal in a transmit chain of a transmitter is provided. The method includes adjusting a controllable gain level of a digital-to-analog converter based on a desired peak-to-average ratio of a transmit signal envelope, adjusting a digitally controlled discrete gain-step amplifier, the amount of gain per step based on an initial estimate of the transmitter gain and a target power, applying a factor to a gain adjuster responsive to the gain step change in the transmit chain, and repeating the adjusting and applying steps until a feedback signal level exceeds a reference signal level. | 01-22-2015 |
