摘要:
There is provided a fall detection system for use in detecting falls by a user, the fall detection system comprising a processing unit configured to determine context information about the user and/or the environment in which the user is located, and to increase the sensitivity of a fall detection algorithm used to detect falls by a user in the event that the determined context information indicates that the user is or may be at an increased risk of falling, the increase in sensitivity occurring while the increased risk of falling is indicated by the determined context information.

A garment (12) is intended to identify a danger situation for the user and react. The garment comprises an emergency device (13) provided with sensors. Furthermore, the emergency device comprises an electronic processing unit (16) and a supervisor and communication unit (17). The supervisor and communication unit (17), after being informed of the danger situation by the electronic processing unit, monitors the user by means of the sensors and assesses the level of user activity in order to decide or not to call for further assistance.

The present invention provides a monitoring system having an alarm base and one or more remote sensors and data collecting devices. The alarm base and remote sensors communicate over a wireless connection and use a frequency hopping technique to implement a highly efficient communication protocol. By predefining and fixing both hop channels and ordering, the system is able to operate with reduced power demand. The communication protocol has very low power requirements in the alarm base and even lower power requirements in each of the remote sensors. The communication protocol is robust providing 100% data communications even at the edge of range,

The present invention relates to a method for a surveillance system, comprising the steps of receiving an image from a surveillance camera capturing a sequence of images of a predetermined area, detecting motion within the predetermined area, generating an alarm if motion is detected, determining the type of alarm, setting a non-alarm area within the image if the type of alarm is determined to be on a list of predefined alarm types, and suppressing, for a predefined time period, detection of motion in the non-alarm area. The invention also relates to a corresponding surveillance system and a computer program product.

An improved ceiling mount assembly (10) for supporting a connected electrical device so that it can be temporarily lowered from a ceiling to facilitate servicing comprising: an upper member (12); a lower member (14); and a tether line (18), the first end of which is connected to a mechanical (non-motorised) extension/retraction unit (16) within the upper member (12; and the second end of which is attached to the lower member (14); such that in use when said electrical device (E) is mounted underneath the lower member, both may together be raised or lowered relative to the upper member that is fixed to the ceiling (C).
摘要:
For monitoring a battery status of a battery included in a mobile communication device (1), battery status reports are received (S12) in a computerized service unit (2) via a mobile radio network from the mobile communication device (1). The battery status reports include at least an electrical battery parameter indicative of a current charge or voltage level of the battery. Based on the battery status reports, received from the mobile communication device (1), battery data is stored (S17) in the computerized service unit (2), the battery data including at least a time series of the electrical battery parameter. Using the battery data, determined is a deviation of a battery parameter, included in the battery status report, from an expected value of the battery parameter derived from the battery data.
摘要:
Ein optischer Rauchmelder (1) mit einem Gehäuse (2) und einer Messkammer (4) in dem Gehäuse (2), mit einem optischen Sensor (6) zur Detektion von Streulichtpartikeln in der Messkammer (4) und mit einer Auswerteeinheit (9) (A 1 , A 2 , ..., An) zur Abfrage des optischen Sensors (6) in mehreren Zeitintervallen zeitlich nacheinander wird beschrieben. Die Auswerteeinheit (9) ist zur Abgabe einer Rauchwarnung in Abhängigkeit von den Sensorsignalen für eine Gruppe von den Sensorsignalen für eine Gruppe von mehreren zeitlich nacheinander durchgeführten Abfragen (A 1 , A 2 , ...,A n ) eingerichtet. Die Zeitintervalle (Δt 1 , Δt 2 , ...., Δt n ) einer Gruppe von Abfragen (A 1 , A 2 , ..., An) sind voneinander unterschiedlich.
