20140188008 | Device for Measuring Spinal Mobility - A device and method for measurement of spinal mobility are provided for measuring spinal mobility. The apparatus is a hand-held device that includes a gripping portion connected to a force transmitter, a reference member, displacement sensor, and load cell. A force applied downwardly on the gripping portion is transmitted to the force transmitter which is placed on a vertebra of the spine of a subject. The reference member rests on an adjacent vertebra. The displacement sensor determines displacement of the force transmitter relative to the reference member, as a function of the applied force measure by the load cell. | 07-03-2014 |

20080312813 | SYSTEM AND METHOD FOR PREDICTING VEHICLE ROLLOVER USING POSITION TRACKING - A method of predicting vehicle rollover is provided to assist in preventing vehicle rollover. The method contains the steps of: determining a center of gravity of a vehicle; determining an actual lateral acceleration of the vehicle; determining a maximum lateral acceleration of the vehicle; and determining if the actual lateral acceleration is more than a predefined percentage of the maximum lateral acceleration. When the actual lateral acceleration is more than the predefined percentage of the maximum lateral acceleration, a warning is issued to the driver such that preventative measures can be taken to avoid a rollover. | 12-18-2008 |
20100033338 | SYSTEM AND METHOD FOR DETECTING A BOUNDARY CROSSING EVENT - Model zone data and model subzone data is employed to simplify calculations for determining where and/or when a boundary crossing event has occurred. A system for detecting a boundary crossing event employs a memory and a processor. The processor in one embodiment is configured by the memory to perform the steps of sensing current position; comparing the sensed current position to model zone data to determine presence within a geometric figure constructed around a boundary crossing point; comparing the sensed current position to model subzone data to determine presence within a first portion of the geometric figure; comparing the sensed current position to model subzone data to determine presence within a second portion of the geometric figure; and detecting a boundary crossing event as a result of movement from the first portion of the geometric figure to the second portion of the geometric figure. | 02-11-2010 |
20100052882 | SYSTEM AND METHOD FOR IMMOBILIZING A VEHICLE - In accordance with one embodiment, an onboard computer (OBC) and associated circuitry capable of spoofing or mimicking a fault condition tricks an electronic control module (ECM) of an automobile or other such vehicle into implementing an engine derate procedure resulting in vehicle immobilization that is safe and that is credibly attributable to a genuine vehicle fault condition. For example, in response to an engine shutdown command, the OBC might cause a fault-spoofing engine shutdown device in one embodiment to spoof an engine overheating condition by inserting an electrical resistance in parallel with the resistance of an engine temperature sensor, thus lowering the electrical resistance of the temperature sensor as detected by the ECM. | 03-04-2010 |

20110173320 | NETWORK-SPECIFIC ESTIMATION IN NETWORK NODE DISCOVERY - Network node discovery is implemented using parameters reflecting network-specific characteristics. Estimates of the number of active nodes in a network are computed based on the presence of dead time (e.g., due to clock latency, device driver delays, etc.), network topology, packet size, network capacity, a tolerable network overload threshold, and other characteristics. A network node enumeration process is therefore parameterized to incorporate consideration of such characteristics. A damping factor that incorporates dead time to set a lower bound for an estimate of remaining active nodes in a network is one example of a network-specific parameter. | 07-14-2011 |

20110282656 | Method And Arrangement For Processing Of Audio Signals - Method and decoder for processing of audio signals. The method and decoder relate to deriving a processed vector {circumflex over (d)} by applying a post-filter directly on a vector d comprising quantized MDCT domain coefficients of a time segment of an audio signal. The post-filter is configured to have a transfer function H which is a compressed version of the envelope of the vector d. A signal waveform is reconstructed by performing an inverse MDCT transform on the processed vector {circumflex over (d)}. | 11-17-2011 |

20130006646 | Transform Audio Codec and Methods for Encoding and Decoding a Time Segment of an Audio Signal - Methods and devices for efficient encoding/decoding of a time segment of an audio signal. Methods comprise deriving an indicator, z, of the position in a frequency scale of a residual vector associated with the time segment of the audio signal, and deriving a measure, Φ, related to the amount of structure of the residual vector. The methods further comprise determining whether a predefined criterion involving the measure Φ, the indicator z and a predefined threshold Θ, is fulfilled, which corresponds to estimating whether a change of sign of at least some of the non-zero coefficients of the residual vector would be audible after reconstruction of the audio signal time segment. The amplitude of the coefficients of the residual vector is encoded, and the signs of the coefficients of the residual vector are encoded only when it is determined that the criterion is fulfilled, and thus that a change of sign would be audible. | 01-03-2013 |

20140288925 | BANDWIDTH EXTENSION OF AUDIO SIGNALS - Audio decoder and method therein for supporting bandwidth extension (BWE) of a received signal. The method involves receiving a first signal representing the lower frequency spectrum of a segment of an original audio signal; receiving a second signal, being a BWE signal, representing a higher frequency spectrum of the segment of the original audio signal. The method further comprises determining a degree of voicing in the lower frequency spectrum of the audio signal, based on the received first signal; and selecting a spectral tilt adaptation filter, out of at least two spectral tilt adaptation filters having different spectral attenuation characteristics, based on the determined degree of voicing. The selected spectral tilt adaptation filter is then applied on the received second signal. Thus, a differentiation of spectral tilt in the higher frequency spectrum of a reconstructed audio signal, based on lower frequency spectrum characteristics of the original audio signal is enabled. | 09-25-2014 |
