摘要:
According to the present invention, a light guidance system for adapted illumination in emergency or power cut situations is provided, wherein the light guidance system is connected to an auxiliary power supply system (101) and comprises at least one light unit (103) adapted to emit light for illuminating surroundings and a control unit adapted to increase a light level of the light unit (103) according to a presence signal indicating the presence of a person, wherein the increasing of the light level is adjusted to enable a mandatory lighting period and a mandatory light level by considering a power value of the auxiliary power supply system (101).

Systems and methods for forming a local network (150) include determining which controllable (120) and controlling (170, 180) devices are located within a local area (110). A controller (130) is configured to communicate with the controllable and controlling devices and to include local devices to the local network (150) associated with the local area, while preventing remaining devices from being associated with the local network. The controller may be further configured to automatically reconfigure itself and/or the local controlling device(s) to properly be commissioned to control the local controllable device(s), such as based on the number and/or type of the local controlling devices allowed to join the local network. The controller distinguishes and determines the local controllable and controlling devices by RF signals, IR signals and/or sonar signals, such as based on time of flight and received signal strength of the RF signals.

A method (100) of controlling an outdoor lighting system, a computer program product, a controlling device for controlling an outdoor lighting system and an outdoor lighting system are provided. The outdoor lighting system comprises outdoor lamps which are distributed over spatial segments of an outdoor space. The emitted light intensity of the outdoor lamps is controllable per spatial segment, and references are used to refer to specific spatial segments. The method (100) comprises the steps of (i) receiving (102) from a detection system an indication of a sub-area of the outdoor space and receiving at least one activity property or the sub-area, the detection system being arranged for detecting activity in the sub-area, the sub-area being different from all the spatial segments, and the indication being used to refer to the sub-area, and the at least one activity property being related to a traffic density in the sub-area (ii) mapping (104) the at least one indication to at least one reference of a respective spatial segment, (iii) determining (106) a light intensity level for the respective at least one spatial segment in dependence on the received at least one activity property, (iv) providing (108) the at least one reference together with the respective determined light intensity to the outdoor lighting system.

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.
摘要:
The invention relates to an installation tool for RF (Radio Frequency) networks, such as a wireless networked control system, for example a wireless lighting system. A basic idea of the invention is to provide an installation tool, which allows controlling a setting of a device by performing a simple and intuitive action with the tool, for example turning the tool like a screwdriver. An embodiment of the invention provides an installation tool (10) for a wireless network of devices, wherein the tool comprises a transceiver (12) to communicate wirelessly information with devices of the wireless network, an action detector (14) for detecting a user action with the tool, and a controller (16) configured to control a setting of one or more devices by means of the wireless transceiver upon receipt of an action signal from the action detector. The invention helps to make the installation of a wireless network, particularly of controlling settings of devices of a wireless network more simple and intuitive for a user by applying the inventive tool than using PDA or computer for installation.
