Abstract: A system for managing a call includes a virtual caregiver that assists callers of a monitoring service in response to data received from a monitoring device. The virtual caregiver includes conversation analyzer that initiates a call to a user of the monitoring device and performs a conversation with the user during the call. The conversation is performed by generating audible comments in a synthesized voice to interact with the user. The audible comments are generated to elicit voice responses from the user containing information corresponding to the sensor data. The conversation analyzer also analyzes audible features of the voice responses using one or more models to interpret a condition of the user, generates a decision based on the interpreted condition of the user, and performs at least one action based on the decision.

Abstract: The present invention relates to a system (100), a method (200) and a computer program for adapting power usage of a mobile unit (110) that is configured to communicate data to a base unit (120). In wearable/portable modules, the power needed by an ISM radio link between the wearable/portable mobile unit (110) and the (quasi-)stationary base unit (120) is determined primarily by the attenuation of the transmitted wave between transmitter and receiver. By monitoring the power setting needed for the transmitter to maintain the link, that information can be used to optimize the position of the base unit (120) for achieving lowest power consumption in the battery operated mobile unit (110).

Abstract: A device (10) for converting a movement of a user into a voltage comprises a neck cord (20), a piezoelectric sensor (30) and a printed circuit board (40). The neck cord is coupled to the piezoelectric sensor and provides in use a pulling force that acts on the piezoelectric sensor in a first direction. The printed circuit board is electrically and mechanically coupled to the piezoelectric sensor. The weight of the printed circuit board cause in use a gravity force to act on the piezoelectric sensor in a second direction, which differs from the first direction such that the movement of the user (5) wearing the neck cord causes a change in the shape of the piezoelectric sensor which in response thereto generates the voltage. The voltage may be used as a supply source for an electrical component (41) mounted on the PCB, or may be used as a wake-up signal for an electrical component such as a processor (41) or an accelerometer.
