Abstract: A person support apparatus, such as a bed, stretcher, cot, recliner, or the like, includes an exit detection system having a plurality of force sensors that support the weight of an occupant positioned on a support surface. The force sensors are part of an exit detection system that issues an alarm when the occupant exits, or is about to exit, the person support apparatus. The distribution of weight applied to the force sensors is used to determine if the occupant is about to exit the person support apparatus. Compensation is made to the exit detection system for changes in the weight distribution that are not caused by movement of the occupant. Such changes may be due to siderail movement, support surface pivoting, and/or movement of other components of the person support apparatus.

Abstract: In a threshold estimation apparatus, a setting unit sets an initial intensity value for each electrode. A selection unit randomly selects an electrode. A stimulation unit, via the selected electrode, stimulates a living subject at an intensity set for the electrode. A detection unit detects the presence or absence of a response evoked by the stimulation. An update unit reduces or increases the intensity associated with the selected electrode, based on the presence or absence of the response evoked by the stimulation. An estimation unit, if the thus updated intensity associated with each electrode satisfies a convergence condition, estimates a convergence value as a threshold associated with the electrode. The threshold estimation apparatus repeats these processes until thresholds associated with all electrodes are estimated. If the same electrode was consecutively selected, the time interval between a stimulation and a subsequent stimulation is adjusted.

Abstract: Methods, systems and apparatuses of ultra-miniature, ultra-compliant probe arrays that allows for design flexibility to match the stiffness of the tissue it is being applied to, such as the brain tissue, in all three axes (x, y and z), with interconnect cross section smaller than cell dimensions. Stiffness matching requires specific geometric and fabrication approaches, commonly leading to ultra-thin probe wires. Sizing of the electrodes for specific cell dimensions reduces glial formation. Further reduction in stiffness is obtained by incorporating different geometric features to the electrode, such as meandering the electrode wires. The small thickness and geometric features of the wires commonly result in very high compliance.

Abstract: The invention provides a system to better detect the onset of congestive heart failure (CHF). The system consists of two primary components—the CHF Index Graph (CHFIG) and a body-worn sensor for measuring the necessary parameters—that correctly measure and analyze a set of parameters related to CHF. The CHFIG typically consists of 7 or 8 unique axes, each corresponding to a different CHF-related parameter. Each axis is normalized and scaled so that the plotted values trend outwards as a patient's trajectory towards CHF worsens. Titus, the area of a region constructed from the plotted values of the parameters increases as the values move further away from the center of the graph; this indicates the patient is trending towards CHF. Conversely, a healthy patient's parameters will be clustered relatively close to the center of the graph, creating a region with a much smaller area.

Abstract: An apparatus (1) and method for detecting pulse-related parameters, such as pulse arrhythmia is presented. The apparatus (1) detects a series of pulses from a user, e.g. through a cuff-related measurement. Time differences, amplitude and pattern differences between multitudes of N pulses are determined. The apparatus investigates the degree of similarity of multiple pulse periods and/or pulse amplitudes and/or pulse pattern and subsequently generates a statistical set of similarity values based on a plurality of compared results. Basing on this, the apparatus generates a decision value based on the statistical sets of similarity values, and uses the decision value to determine whether or not the user discloses a normal pulse rhythm, atrial fibrillation, premature atrial or ventricular contractions, tachycardia, bradycardia and/or unspecified pulse arrhythmia. Further an artefact index is generated, informing the user whether a measurement was taken under sufficient artefact-free measurement conditions.
