20110105955 | OMNIDIRECTIONAL ACCELEROMETER DEVICE AND MEDICAL DEVICE INCORPORATING SAME - A portable medical device is provided with an internal accelerometer device. The medical device includes a circuit board, the accelerometer device, and a response module coupled to the accelerometer device. The accelerometer device is mechanically and electrically coupled to the circuit board, and it includes a plurality of mass-supporting arms for a plurality of electrically distinct sensor electrodes, piezoelectric material for the mass-supporting arm, and a proof mass supported by the mass-supporting arms. Each of the mass-supporting arms has one of the sensor electrodes located thereon. Acceleration of the proof mass causes deflection of the piezoelectric material, which generates respective sensor signals at one or more of the sensor electrodes. The response module is configured to initiate an acceleration-dependent operation of the portable medical device in response to generated sensor signals present at the sensor electrodes. | 05-05-2011 |

20150265150 | SYSTEMS AND METHODS FOR PERFORMING AN IMAGING TEST UNDER CONSTRAINED CONDITIONS - An imaging system collects a plurality of images of an extremity of a subject, each collected at a unique spectral band. A physiologic arterial parameter of the extremity is determined from the plurality of images upon image registration. A record of the physiological arterial parameter is recorded in an electronic data store and an indication of the parameter is outputted. The method is performed by a medical professional associated with a temporal clinical expenditure cost in an epoch, for an entity. The product of the (i) epoch and the (ii) temporal clinical expenditure cost is less than a difference between (a) an average or absolute reimbursement associated with the current procedural terminology code by the entity and (b) incidental expenditures associated with the performance of the method. | 09-24-2015 |
20150265195 | SYSTEMS AND METHODS FOR MEASURING TISSUE OXYGENATION - The disclosure provides methods and systems for determining tissue oxygenation. An electronic device obtains a data set including a plurality of images of a tissue of interest, each resolved at a different spectral band. Spectral analysis is performed, upon image registration, at a plurality of points in a two-dimensional area of the images of the tissue. The spectral analysis including determining approximate values of oxyhemoglobin levels and deoxyhemoglobin levels at each respective point in the plurality of points. The predetermined set of eight to twelve spectral bands includes spectral bands that provide improved methods for measuring tissue oxygenation. | 09-24-2015 |
20150271380 | COMPACT LIGHT SENSOR - Provided are methods and systems for concurrent imaging at multiple wavelengths. In one aspect, a hyperspectral/multispectral imaging device includes a lens configured to receive light backscattered by an object, a plurality of photo-sensors, a plurality of bandpass filters covering respective photo-sensors, where each bandpass filter is configured to allow a different respective spectral band to pass through the filter, and a plurality of beam splitters in optical communication with the lens and the photo-sensors, where each beam splitter splits the light received by the lens into a plurality of optical paths, each path configured to direct light to a corresponding photo-sensor through the bandpass filter corresponding to the respective photo-sensor. | 09-24-2015 |
