In particular, spatially dense mode shapes are determined using acceleration records collected when one or several sensors are moving.

Abstract: A user obtains an individual's body temperature data and transmits the data to a medical monitor (e.g., a medical device) for display. Additional data includes a timestamp and location of the body temperature data. Once the data is transmitted, a user may view the medical monitor for a temperature reading. For example, a doctor may take a patient's temperature and the temperature reading is displayed on a medical monitor. The body temperature data of each patient is detected using a preferred temperature detector, such as a temporal artery thermometer using an arterial heat balance approach. After collecting an individual's body temperature data, the body temperature data can be transferred to a processor. By sending body temperature data for many individuals for a geographic region, the processor can identify a pattern (e.g., a pandemic) in the body temperature data.

Abstract: A method for estimating and tracking locally oscillating signals. The method comprises the steps of taking measurements of an input signal that approximately preserve the inner products among signals in a class of signals of interest and computing an estimate of parameters of the input signal from its inner products with other signals. The step of taking measurements may be linear and approximately preserve inner products, or may be non-linear and approximately preserves inner products. Further, the step of taking measurements is nonadaptive and may comprise compressive sensing. In turn, the compressive sensing may comprise projection using one of a random matrix, a pseudorandom matrix, a sparse matrix and a code matrix. The step of tracking said signal of interest with a phase-locked loop may comprise, for example, operating on compressively sampled data or by operating on compressively sampled frequency modulated data, tracking phase and frequency.

Abstract: An apparatus, method and program for estimating the mass of a vehicle uses periodically detected tire rotation speed information of the vehicle wheels, calculated tire rotation acceleration information, calculated driving force of the vehicle, and estimated mass of the vehicle as a regression coefficient when the rotation acceleration information and the driving force information are subjected to linear regression. With regard to an error in calculated driving force information, a ratio is calculated between the dispersion of the error obtained one time before and an error at the current moment, and an update adjustment parameter is calculated by adding a stabilization parameter to thus obtained ratio. The calculated update adjustment parameter is used to calculate a Kalman gain so that the mass is sequentially estimated so as to reduce an update width of the regression coefficient when the error ratio is higher.
