| 20100250170 | INTERROGATION METHOD FOR PASSIVE WIRELESS SENSOR INTERROGATION SYSTEM - A method of wirelessly interrogating a sensing device comprising a plurality of passive sensors, to determine a measurement parameter, comprises the steps of repeatedly interrogating the sensing device using a predetermined transmission signal and detecting the response; estimating the measurement parameter for each sensor by means of an analysis of the data accumulated as a result of the interrogation step, and determining the average of the parameters derived from the estimating step for each sensor, using a weighted average, in which the weightings depend on the amplitude of the sensor response. The measurement parameter may be a resonant frequency where the passive sensors are resonant devices, and the sensors may be SAW devices. | 09-30-2010 |

| 20090314104 | TORQUE MEASUREMENT WITHIN A POWERTRAIN - Aspects of the present invention are directed to using surface acoustic wave (SAW) sensors mounted on a disc coupling component in a powertrain to measure the torque generated by an automobile engine. The sensor may be positioned and oriented on the disc coupling component so that the phase velocities of SAWs propagating through active elements of the SAW sensors are aligned with principal strain components due to torque in the disc coupling component. The torque may be calculated by determining the difference between resonant frequencies of the active elements to suppress common-mode interference factors. In addition, SAW resonant frequencies may be communicated in a non-contacting manner by utilizing rotary and stationary couplers employing radio frequency (RF) signals. Moreover, SAW sensors may be activated and interrogated by employing targeted RF pulses having different carrier frequencies at or near respective resonant frequencies of each resonator in a SAW sensor. | 12-24-2009 |

| 20090055120 | CALIBRATION COEFFICIENTS FOR SENSOR BASED MEASUREMENTS - A method, system and device for providing device specific calibration data for a sensor. A sensor device includes a transmitter, receiver, memory and a response portion responsive to a selected condition of the region. Generic calibration data associated with a group of sensors into which the sensor device falls is then stored in a database remote from the sensor device. Correction data for use in modifying the generic calibration data to more accurately fit the actuation calibration data of the sensor device is stored in the memory portion of the sensor device. The sensor device is interrogated with an interrogator device to obtain the correction data, and the generic calibration data relating to the sensor device is retrieved from the database and modified using the correction data to produce sensor device specific calibration data. | 02-26-2009 |

| 20120094869 | MICROPLATE ASSAY KIT - The present invention provides a microplate-based assay kit that incorporates all assay reagents and standards in a simple and efficient format and may be used in biochemical assays. The assay kit includes pre-filled, pre-sealed and barcoded microplates with a standard physical footprint for use in a microplate-based automated analyzer system which enables simple and efficient operation by an unskilled user via per-use factory-sealed and barcoded reagent and calibrator microplates. Such microplates allow the user to run a broad test menu without the need to monitor the arrangement and supply of internally stored reagents and standards, thus greatly simplifying the user experience and eliminating the need for highly skilled users. | 04-19-2012 |
