摘要： There is provided a device and a method of operating the device for determining whether the device is immersed in a fluid. An acceleration signal for the device is acquired (302) and a pressure within the device is detected (304). It is determined whether the device is immersed in a fluid based on a comparison of the acquired acceleration signal with the detected pressure (306).

摘要： Presented are concepts for monitoring the liquid or food consumption of a person. Once such concept employs the step of detecting a change in weight of the person resultant from usage of a toilet. A value representative of at least one of liquid consumption and food consumption of the person may then be determined based on the detected change in weight of the person.

摘要： An ADL monitoring system uses a set of sensors each adapted to respond to an activity and to generate a sensor output signal representative of the detected activity level or type. An activity density map is formed. The activity level or type is compared with a range of activity levels or types represented in a map which characterized a reference spread of activity levels over the same time period as the activity density map. A probability analysis is then used to identify initial anomaly points. For these the initial anomaly points, a test of activity permutations is carried out to find timeslots in the activity density map which may be reordered to remove the initial anomaly points. In this way, anomalies at the level of individual timeslots can be identified, and the permutation approach makes the system robust to changes in the order in which activities are carried out by a subject.

摘要： A mechanism for setting one or more thresholds for post-discharge monitoring of a target subject. The thresholds are set to be time-dependent, so that the current value of the threshold depends upon a time since the target subject has been discharged from a clinical environment.

摘要： In a personal emergency response system (PERS), a subscriber wears a personal help button (PHB) (10) with a call button (12). A speakerphone console (30) detects a signal transmitted by the PHB when the call button is pressed and establishes a telephone call with a PERS center (8). The PHB, speakerphone console, or combination thereof also performs a check-in process including: detecting (50) a check-in time and outputting (52) a request to perform a check-in action and detecting (54) whether the check-in action is performed. The check-in action is logged (56) if it is detected. A remedial action (60, 62, 64, 66, 68, 70, 72) is performed if the check-in action is not detected. The check-in action may be a designated motion of the PHB detected by gesture recognition algorithm performed by the PHB that analyzes sensor data generated by a motion sensor (22) of the PHB.

摘要： A methods is provided for reliable and accurate detection of opening or closing of doors or drawers using output signals generated by a sensor, the output signals directly or indirectly representative of the acceleration of the sensor over time. Areas under a curve for acceleration, or representations thereof, are determined and occurrence of movement events identified through comparison of calculated areas with certain thresholds. Areas are considered which span between zero crossing points of the acceleration curve, such that all elements of the corresponding sum are of the same sign, and consequent area signals have maximal amplitude. Pairs of substantially equal and opposite area signals may be sought, occurring within a given time separation, these characteristic of an opening or closing motion, consisting of a first acceleration in a first direction followed by a second in an opposing direction. Apparatus for the reliable detection of opening or closing events is also provided.

摘要： The present invention relates to sleepiness assessment. In order to provide a more accurate measure to predict OSA severity, an apparatus is provided for sleepiness assessment. The apparatus comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive data indicative of an activity currently performed by a user. The processing unit is configured to determine, based on the activity currently performed by the user, a current situation the user is engaging in. The processing unit is configured to determine whether the current situation matches one of a plurality of pre-determined situations used for situational sleepiness assessment. In response to the determination that the current situation matches one of the plurality of predetermined situations, the processing unit is configured to send a notification to the user for a self-report of a user's current subjective sleepiness level and/or obtain a user's current objective sleepiness level from sensor data. The processing unit is further configured to generate, based on the determined situation and the user's current subjective and/or objective sleepiness level, a situational sleepiness profile indicative of a sleep disturbance on daytime sleepiness in specific situations. The output unit is configured to provide the generated situational sleepiness profile, which is preferably useable to support sleep apnea diagnostics.

摘要： There is provided an apparatus and a method of operating the apparatus. The apparatus comprises a processor configured to acquire a time-stamped series of environmental property measurements from at least one sensor of a device and compare the time-stamped series of environmental property measurements acquired from the at least one sensor of the device to one or more time-stamped series of corresponding environmental property measurements acquired from at least one sensor that is separate from the device. The processor is also configured to determine contextual information for the device based on the comparison of the time-stamped series of environmental property measurements.
