A hand-held device, such as a remote control, is provided for operation of a consumer appliance and is equipped with one or more biometric sensors to capture and report on the health condition of a user of the hand-held device. The data captured by such a hand-held device may be evaluated locally in the hand-held device itself or may be conveyed to a target consumer appliance either for local evaluation by that consumer appliance or for onward transmission to a central off-site monitoring service.

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

In a magnetic resonance (MR) apparatus and an operating method wherein the MR apparatus has a scanner with a patient table that can be moved into a patient receiving region of the scanner, the patient table is held in an extended loading position, and three-dimensional scanning data describing the surface of a patient positioned in the loading position on the patient table are recorded with a 3D camera, which has a field of view that covers the patient table in the loading position. For the determination of at least one patient-related recording parameter, the scanning data are evaluated for the subsequent recording MR data.

Disclosed is a technique of determining a driver's tension level (tension state degree) in vehicle driving in detail with a simple configuration. According to the technique, a nonlinear analyzing unit 110 of a driver's tension level determining apparatus 100 determining the tension level in driving of a driver acquires the driving operation amounts relating to driving operations of a driver (the operation amounts relating to operations of an accelerator pedal, a brake pedal, a handle, and the like), and then calculates the Lyapunov exponents about the driving operation amounts by performing nonlinear analysis processing. A frequency spectrum analyzing unit 120 calculates the power spectral density of time series data of the Lyapunov exponents, and then calculates an integrated value of a predetermined low frequency band in the calculated power spectral density. A driver's tension level determining unit 130 determines that the driver's tension level is any one of an excessive tension state, a moderate tension state, and an insufficient tension state using the integrated value of the predetermined low frequency band.

A non-invasive testing apparatus for determining a concentration of a target substance, such as blood sugar, blood alcohol, cholesterol, etc., in a patient's blood is disclosed. The apparatus and method involve applying an output RF signal (102) to the skin of a patient via an antenna (20), and measuring the amplitude and phase of a response signal, which is a function of the output RF signal (102) modified by an interaction with the patient's blood. The invention takes measurements at different output RF frequencies (310), and plots the response (300) as a function of frequency (310). The invention is essentially characterised by deriving various derived parameters (552, 554, 556, 550, 408, 410) from the shape of the resulting plots, namely any or more of: a resonance frequency shift; a Q factor of the resonance; a group delay; a phase shift; an amplitude variation; a shape factor of the plot; and a gradient of the plot at different frequencies. The invention utilises models of the derived parameters as a function of concentration of the target substance in blood to arrive at a determination of the latter. Also disclosed is a novel circuit (1000) for obtaining the amplitude and phase measurements, a calibration device (5008), and various improvements relating to wearable non-invasive testing apparatus (3000, 4000).

Systems, methods and devices for validating and performing operations on homomorphically encrypted data are described herein. The methods include securely transmitting and extracting information from encrypted data without fully decrypting the data. A data request may include an encrypted portion including a set of confidential data. One or more sets of encrypted comparison data may be then retrieved from a database in response to the data request. The encrypted set of confidential data from the data request is then compared with each set of encrypted comparison data using one or more homomorphic operations to determine which set of encrypted comparison data matches the encrypted set of confidential data. If there is a match, this validates the set of confidential data. An encrypted indicator is then generated indicating success or failure in validating the set of confidential data, which may then be forwarded to a party associated with the data request.

A method for monitoring an occupant of an occupant support comprises 1) establishing a lateral position history of the occupant, which history includes an assessment of how frequently the occupant's head undergoes a lateral transition on a head support, 2) establishing a vertical position history of the occupant which accounts for how frequently the weight of the occupant's head is applied to and removed from the head support, and 3) if the lateral position history indicates sustained repetitive lateral movement or the vertical history indicates other than sustained presence of the occupant's head on the head support, reporting that the occupant is in a state other than an acceptable state.

A physiological parameter tracking system has a reference parameter calculator configured to provide a reference parameter responsive to a physiological signal input. A physiological measurement output is a physiological parameter derived from the physiological signal input during a favorable condition and an estimate of the physiological parameter according to the reference parameter during an unfavorable condition.
