20120114077 | VARIABLE DYNAMIC RANGE RECEIVER - Embodiments of the present invention may provide a signal processing circuit that may comprises an analog-to-digital converter (ADC), and an output restriction circuit. The output restriction circuit may reduce the accuracy of the digital output of the ADC when signal content exceeds a pre-determined spectrum mask in an undesirable band. In one embodiment, the input signal spectrum may be actively monitored and when the input spectrum is inconsistent with an intended application, the output resolution may be restricted, for example, by truncating least significant bits (LSBs) of the digital output or adding digital noise. | 05-10-2012 |

20100073210 | Pipelined converter systems with enhanced linearity - Signal converter system embodiments are provided to substantially reduce symmetrical and asymmetrical conversion errors. Signal-processing stages of these embodiments may include a signal sampler in addition to successively-arranged signal converters. In system embodiments, injected analog dither signals are initiated in response to a random digital code. They combine with a system's analog input signal and the combined signal is processed down randomly-selected signal-processing paths of the converter system to thereby realize significant improvements in system linearity. Because these linearity improvements are realized by simultaneous processing of the input signal and the injected dither signal, a combined digital code is realized at the system's output. A first portion of this combined digital code corresponds to the analog input signal and a second portion corresponds to the injected analog dither signal. The final system digital code is realized by subtracting out the second portion with a back-end decoder that responds to the random digital code. | 03-25-2010 |

20100176919 | ONE-TIME ACCESS FOR ELECTRONIC LOCKING DEVICES - Systems and methods for providing one-time access to electronic locking devices for non-keyholders. The one-time access rights are delivered from a server to the electronic locking device in real-time, or in near-real time, over short and long-range wireless communication links in a manner that is secure and traceable. A handheld device is coupled with the electronic locking device via the short-range communication link, and is coupled with the server via a long-range wireless communication link. | 07-15-2010 |

20130124997 | Digital video system with intelligent video selection timeline - A digital video system comprises a plurality of recorders and a client device. The recorders store digital video from a common source. The client device comprises a screen, an input device, and a processor configured to run a graphical user interface (GUI). The GUI comprises a timeline, a selection indicator, availability indicators, and event tags. The timeline is adjustable by user input. The selection indicator is movable on the timeline by user input, and designates a time of interest. The availability indicators indicate aggregate availability statuses of video at each time on the timeline, from the plurality of recorders. The event tags indicate types and times or time ranges of events on the timeline. The client device is configured to receive video availability information from the plurality of recorders, and the processor is configured to update the GUI as the aggregate availability status of video changes. | 05-16-2013 |

20150300963 | COMPUTERIZED TOMOGRAPHY DETECTION OF MICROBIAL DAMAGE OF PLANT TISSUES - The present disclosure encompasses embodiments of X-ray computed tomography-based methods for the detection of onion quality factors. Such methods are advantageous in detecting internal damage to onion bulbs due to bacterial and fungal rots and mechanical damage while also providing for the overall assessment of onion bulb quality and market value. Because CT images provide cross-sectional reconstructions of the subject under study, CT scans of onion bulbs can be used not only to detect damage from disease, but also cuts and bruises that increase an onion bulb's susceptibility to disease, and the presence of shoots or seed stems and overall shape of the bulbs. | 10-22-2015 |

20110158825 | SYSTEM AND METHOD FOR MODIFYING AN AUTOMOBILE ENGINE FOR USE AS A GAS COMPRESSOR - In accordance with various embodiments of the present invention, a system and method are provided for converting a conventional automobile engine into a gas compressor. In various embodiments, the system and method may provide an economical and efficient gas compressor by modification of a balance-opposed internal-combustion engine to provide a balance-opposed gas compressor. More specifically, in some embodiments, the modification may include a uniquely designed cylinder head adapted to convert an automobile engine into a gas compressor for the recovery, gathering, transfer, or staged compression of natural gas. In one embodiment, a four-cylinder balance-opposed engine is utilized. | 06-30-2011 |
