20090152390 | CABLE DESPOOLING AND SPOOLING - In some embodiments, a cable spool includes a hub having an outer surface that is retractable and expandable, and a single end plate affixed to an end of the hub. In other embodiments, an apparatus includes an assembly of cascaded, temporarily interlocked spools that can be used for simultaneous despooling or spooling of multiple cable coils. | 06-18-2009 |
20090268555 | METHOD AND APPARATUS FOR IDENTIFYING NOISE SOURCES - A computer implemented method and apparatus for identifying component breakdown of noise sources. Noise data is received for a noise source from an array of sound sensors. Measurement points of interest, candidate sound source points along an axis, and array aperture angles are identified. Sets of first and second bounding traces are identified from ray traces extending from the candidate noise source points towards the measurement points of interest using the array aperture angles. The bounding ray traces are rotated around the axis to form sets of first and second surfaces. Sets of first and second curves are identified from an intersection of the sets of first and second surfaces with the ground plane. Sound sensors are selected from the array using the curves to form subarrays. The component breakdown of noise generated by the noise source is identified using noise data from sound sensors in the subarrays. | 10-29-2009 |
20100114534 | CONSTANT CURRENT POWER SOURCE ELECTRONICS FOR A SENSOR - An apparatus comprises a sensor and a circuit. The sensor is capable of generating a signal in response to detecting a stimulus. The circuit is capable of powering the sensor and providing multiple other capabilities including signal conditioning, non-signal related noise cancellation, and signal transmission using a constant current source power input from a cable and sending the signal over the cable. | 05-06-2010 |
20130336511 | Micro-Sensor Package And Associated Method Of Assembling The Same - A micro-sensor package is provided that includes a micro-sensor and printed circuit board (PCB), or that includes an array of micro-sensors and PCB. The micro-sensor includes a first substrate having opposing front and back surfaces, a sensing element on the front surface of the first substrate, and a through-chip via disposed within the first substrate and electrically connected to the sensing element. The PCB includes a second substrate to which the back surface of the first substrate is bonded. The second substrate defines a recess within which a bond pad is disposed, and the through-chip via of the micro-sensor is electrically connected to the bond pad of the PCB. The micro-sensor package may further include a shim bonded to the PCB, and that may surround an outer boundary of the micro-sensor and have approximately the same thickness as the micro-sensor. | 12-19-2013 |
