20100324629 | IMPLANTABLE LEAD FUNCTIONAL STATUS MONITOR AND METHOD - A system for monitoring trends in lead impedance includes collecting data from various sources in an implantable medical device system. Lead impedance, non-physiologic sensed events percentage of time in mode switch, results of capture management operation, sensed events, adversion pace counts, refractory sense counts and similar data are used to determine the status of a lead. A set of weighted sum rules are implemented by a software system to process the data and provide displayable information to health care professionals via a programmer. The lead monitoring system includes a patient alert system for patients to seek help in the event a serious lead condition is identified. | 12-23-2010 |

20150144877 | VERTICAL SEMICONDUCTOR DEVICES INCLUDING SUPERLATTICE PUNCH THROUGH STOP LAYER AND RELATED METHODS - A semiconductor device may include a substrate, and a plurality of fins spaced apart on the substrate. Each of the fins may include a lower semiconductor fin portion extending vertically upward from the substrate, and at least one superlattice punch-through layer on the lower fin portion. The superlattice punch-through layer may include a plurality of stacked groups of layers, with each group of layers of the superlattice punch-through layer comprising a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions. Each fin may also include an upper semiconductor fin portion on the at least one superlattice punch-through layer and extending vertically upward therefrom. The semiconductor device may also include source and drain regions at opposing ends of the fins, and a gate overlying the fins. | 05-28-2015 |

20110006822 | Open-Loop Line Driver Control Method and Apparatus - According to an embodiment, a circuit includes an amplifier and an open-loop control system. The amplifier has an output stage for amplifying a signal, a power supply for driving a supply voltage of the output stage to different voltage levels responsive to being modulated and a pulse width modulator for modulating the power supply responsive to a mask input. The open-loop control system includes a mask generator and a detector. The mask generator is configured to generate the mask input as a function of the envelope of the signal. The detector is configured to detect discontinuities in the mask input and compensate for the discontinuities. | 01-13-2011 |

20100158258 | Binaural Sound Localization Using a Formant-Type Cascade of Resonators and Anti-Resonators - This invention is a method for binaural localization using a cascade of resonators and anti-resonators to implement an HRTF (head-related transfer function). The spectrum of the cascade reproduces the magnitude spectrum of a desired HRTF. The proposed method provides a considerably more computationally efficient implementation of HRTF filters with no detectable deterioration of output quality while saving memory when storing a large quantity of HRTFs due to the parameterization of its resonators and anti-resonators. Finally, the method offers additional flexibility since the resonators and anti-resonators can be manipulated individually during the design process, making it possible to interpolate smoothly between HRTFs, reduce spectral coloring or achieve higher accuracy at perceptually relevant frequency regions. These HRTF are useful in stereo enhancement and multi-channel virtual surround simulation. | 06-24-2010 |
