摘要:
A presence detection system (1) for detecting a presence of an object (3), particularly a person or an animal or vehicle, within an area (5) divided in detection zones (9A;9B;9C;9D) covering the area. The system comprises a movement detection device (11A;11B;11C;11D) for detecting a movement of the object. The system further comprises an electronic processing device (13) for storing information relating to a position of the object in a zone-wise way, based on a detected movement of the object. The electronic processing device is configured for determining the presence of the object within the area based on a detected movement of the object and stored information relating to the position of the object. The system is highly sensitive and highly prevents false presence detections. The invention also relates to a method for presence detection, and a lighting system comprising the presence detection system.

The present invention refers to a lighting system comprising ambient light sources and task light sources, and occupancy sensors for detecting occupancy in a number of occupancy zones and for controlling the ambient light sources and task light sources. Each occupancy sensor is provided to communicate wirelessly with other occupancy sensors. On the detection of occupancy of at least one zone, the occupancy sensors detecting the occupancy active at least one ambient light source and send a control signal to other occupancy sensors to active other ambient light sources, and the intensity of a group of task light sources illuminating the occupied zone is set to a level higher than the intensity of the remaining task light sources. The invention also refers to a respective method for controlling a lighting system of this kind.

A transducer (800) is provided where a membrane (830) is formed over a front substrate (615); and a piezoelectric layer (820) is formed over the membrane (830) at an active portion (821) and peripheral portions located adjacent the active portion (821). A patterned conductive layer including first and second electrodes (840, 845) is formed over the piezoelectric layer (820). Further, a back substrate structure is provided having supports (822, 824) located at the peripheral portions adjacent the active portion (821). The height (826) of the supports (822, 824) is greater than a combined height (828) of the patterned piezoelectric layer and the patterned conductive layer. Many transducers may be connected to form an array, where a controller may be provided for controlling the array, such as steering a beam of the array, and processing signals received by the array, for presence or motion detection and/or imaging, for example.

The present invention relates to method for wireless communicating in a network comprising a resource-constrained end device, and a first router device, wherein the method comprises the following steps:—the end device (ZBLD) sending a trigger for proxy search procedure,—the first router (R1) device receiving the trigger for proxy search procedure, the first router (R1) determining whether it fulfills conditions for acting as a router for the end device, and in case conditions are fulfilled, the first router appointing itself as a proxy router for the end device, for relaying communication between the end device and the rest of the network. The invention also relates to an end device, a router device, and net work therefor.
摘要:
A node detection system includes an array of nodes (510), wherein each node of the array of nodes (510) has at least at least two, three or four directional antennas (530) configured to have antenna beams in as many directions. The range of each antenna is limited to reach a neighboring operational node of the array of nodes (510) for transmission of a message to the neighboring operational node. A controller (550) is configured to receive messages from the array of nodes (510) and determine the location of each node based on the messages.
摘要:
In a system and method of capturing movement of an object, a tracking device is used having an optical marker and a motion sensor providing motion data representative of the position and orientation of the tracking device. The tracking device is connected to the object, and motion of the optical marker is registered by a camera to thereby provide video data representative of the position of the tracking device. The motion data and the video data are processed in combination to determine the position and orientation of the tracking device in space over time.
