    摘要: A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

    摘要: A method for noninvasively measuring analytes such as blood glucose levels includes using a non-imaging OCT-based system to scan a two-dimensional area of biological tissue and gather data continuously during the scanning. Structures within the tissue where measured-analyte-induced changes to the OCT data dominate over changes induced by other analytes are identified by focusing on highly localized regions of the data curve produced from the OCT scan which correspond to discontinuities in the OCT data curve. The data from these localized regions then can be related to measured analyte levels.

    摘要: The present invention relates to a method for estimating blood glucose levels using a noninvasive optical coherence tomography- (OCT-) based blood glucose monitor. An algorithm correlates OCT-based estimated blood glucose data with actual blood glucose data determined by invasive methods. OCT-based data is fit to the obtained blood glucose measurements to achieve the best correlation. Once the algorithm has generated sets of estimated blood glucose levels, it may refine the number of sets by applying one or more mathematical filters. The OCT-based blood glucose monitor is calibrated using an Intensity Difference plot or the Pearson Product Moment Correlation method.

    摘要: A steering wheel cover that houses the sensor, indicator, power and communication elements of a driver safety system is disclosed. The objective is to discourage texting, eating, primping one's self and cell phone use that distract drivers and causes accidents. The steering wheel cover is light, easy to install and lock in place but strong and difficult to forcibly remove. The driver safety system senses the positions of the driver's hands on the wheel rewarding safe habits. When the system senses bad habits the driver is warned, incidence is recorded for third party information in addition to alerting and annoying dis-rewards are given.

    摘要: This disclosure presents an apparatus and method for automatic gain control correction for a television signal in which the Radio Frequency (RF) and Intermediate Frequency (IF) power signal levels are collected for a band of channels, identifying a channel having a strong RF power signal level and an IF gain signal level that is lower than a nominal IF gain signal level, comparing the identified channel RF gain signal level with the RF gain signal level of adjacent channels to identify the relative power signal levels of the channel and associated adjacent channels, and applying correction to the channel wherein there is an imbalance in the RF and IF power signal levels of the identified channel. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要: A demodulator cancels out the echo signal properties in the received signal to generate a primary signal, and cancels out the primary signal properties in the received signal to generate a separate echo signal. In addition, the demodulator may combine the primary signal and the echo signal in a comparison/combination operation to generate a third combined signal. Error correction operations may then be performed on all three of the primary signal, echo signal and combined signal, with the results of those error correction operations being used to select which of the three signals will serve as the transport stream.
