20090198400 | SYSTEMS AND METHODS FOR CONTROL OF AN UNMANNED GROUND VEHICLE - Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented. | 08-06-2009 |

20120109423 | SYSTEM AND METHOD FOR BEHAVIOR BASED CONTROL OF AN AUTONOMOUS VEHICLE - System and method for behavior based control of an autonomous vehicle. Actuators (e.g., linkages) manipulate input devices (e.g., articulation controls and drive controls, such as a throttle lever, steering gear, tie rods, throttle, brake, accelerator, or transmission shifter) to direct the operation of the vehicle. Behaviors that characterize the operational mode of the vehicle are associated with the actuators. The behaviors include action sets ranked by priority, and the action sets include alternative actions that the vehicle can take to accomplish its task. The alternative actions are ranked by preference, and an arbiter selects the action to be performed and, optionally, modified. | 05-03-2012 |

The automatic variable gain amplifier automatically adjusts the amplification of a signal, and in one embodiment, an ion signal, based on the amplitude of the peaks of the signal. The automatic variable gain amplifier detects the peaks of the signal, compares them to a threshold value, and, based on this comparison, varies the amount by which the signal is amplified. The automatic variable gain amplifier produces a composite output waveform for an input waveform with an amplitude that may vary over a plurality of orders of magnitude. | 09-01-2011 |
20110210745 | Self Power For Ignition Coil With Integrated Ion Sense Circuitry - A self power circuit for ion sense circuitry is provided.

20140040308 | System and Method for Analyzing De-Identified Health Care Data - A system and method for creating a unique alias associated with an individual identified in a health care database such that health care data, and particularly pharmaceutical-related data, can be efficiently gathered and analyzed. The system has a first data store for storing at least one record where each record includes a plurality of identification fields which when concatenated uniquely identify an individual, and at least one health care field corresponding to health care data associated with the individual. The system also has a second data store, and a processor. The processor selects a record of the first data store, then selects a subset of the plurality of identification fields within the selected record, and concatenates the selected subset of identification fields. Then the processor stores the concatenated identification fields in a record in the second data store with the at least one health care field from the selected record of the first data store. | 02-06-2014 |

20130083203 | System and Method for Diagnostic Modeling of Audio and Video Quality of Service - Systems and methods are described for determining a set of three quality metrics for audio and/or video signals transmitted through a packet network. The set of three metrics provide more insight into which factors are affecting the quality of the received signal as perceived by the end-user. These three quality metrics measure reductions in quality due to lossy media transmission, packet loss concealment from packet loss and/or packet/frame jitter, and long periods of silence and/or frozen video. Because each metric quantifies a different aspect of transmitted quality, a deficiency in the transmitted signal can be identified by reference to the set. | 04-04-2013 |

20140326410 | PORTABLE SYSTEM FOR BONDING PIPES - A kit for fusing piping includes a plurality of couplings, each coupling having a susceptor layer concentric with a weld zone. A control unit provides a current to a wand with a handle for gripping by a user. The handle has opposing jaws mounted on the distal end, each jaw including an arcuate conductor such that the arcuate conductors form a circular inner diameter when the jaws make contact. A lever system couples to the distal end for opening and closing the jaws. The lever system includes a spring for selectively biasing the lever system in a latched position with jaws closed and an open position with the jaws open. Each coupling is sized such that the jaws will only close about the weld zone. The arcuate conductors create a fuse zone about the susceptor layer and the spring is outside the fuse zone. | 11-06-2014 |

20130080690 | METHOD TO EMULATE EEPROM USING FLASH MEMORY - Methods of using FLASH memory to emulate EEROM are disclosed. The present method uses two pages of FLASH memory, where each page is one or more separately erasable blocks. One page is referred to as the current page, while the other is the next page. Tokens, which are data structures containing a data element, are written in successive locations in the current page. When the current page is nearly completely filled, the write operation starts writing the new tokens to the next page. In some embodiments, to equalize the execution time of the write routine, the write routine also copies one token from the current page to the next page after a new token is written to the next page. Once all tokens have been copied to the next page, the current page can be erased. At this point, the next page becomes the current page. | 03-28-2013 |
