Abstract: Described herein is a method for marking luminaires, particularly traffic route luminaires, in a luminaire network, the network being controllable via a server. Each luminaire is provided, in its operational state, with a controller (2) for controlling its operation and a mark that is visually recognizable from the outside the luminaire. The mark is formed by an information storage medium (4), in particular, and can be used to identify the luminaire. The mark is linked to the controller (2) or to the luminaire to be controlled by the controller before the mark is added to the luminaire.

Abstract: Described herein is method for the detection of seismic activity using a network of lights, and in particular, street lights (43) arranged over a number of streets (42). Each light includes a control module having the facility for both long- and short-distance communication, the control modules being grouped with other control modules and associated with a group controller to create a short-distance or mesh network. Each control module includes a sensor which is capable of detecting seismic activity and data relating to such activity may be transmitted to a central server via its group controller using long-distance communication. Even if the sensors are relatively inaccurate, the high number of such sensors present in the network makes it possible to detect and analyse the activity using geocoordinate information provided by the control modules at the server.

Abstract: Method for the operation and the expansion of a network of lights, each light in the network including a control module which is assigned to a group, each control module being in communication with a group controller as well as control modules in the same group. The network can be expanded by installing (19) new lights with their associated control modules, and each new control module scans (20) its environment and transmits environmental information to a central server where the environmental information is analysed and the new control modules are allocated (21) into groups. After allocation to a group in which control modules may be moved from one group to another or a new group is formed, the new control modules are available for normal operation. This process is repeated for each new light and associated control module.

Abstract: A method for controlling a streetlight that is provided to illuminate a portion of the street, the method being performed by a controlling device having a memory accessible by a processor which controls a steering module which steering module is operatively coupled to the streetlight.

Abstract: An elevator system and associated method includes power control for operating an elevator (2) in an emergency mode wherein the elevator (2) includes a car (4), a drive motor (10), a motor drive unit (26) which supplies power to the drive motor (10) and controls the same and an emergency power supply (42). The motor drive unit (10) has a predetermined normal operation switching frequency. In an emergency mode, power is supplied to the motor from the emergency power supply (42) while the motor drive unit is in an emergency mode. An actual emergency operation condition characteristic is determined for setting the switching frequency of the motor drive unit (46) dependent on the actual emergency operation condition characteristic.

Abstract: An elevator rescue system includes a power source of back-up electrical power. A manually-operated, rescue enable switch switchably permits the transmission of electrical power from the power source to a motor brake coil of an elevator car during a rescue operation such that the energized coil releases the motor brake to move the car to a desired landing. A speed detector measures the speed of the elevator car and thereupon generates a speed control signal corresponding to the speed of the car. An overspeed detection circuit has a first input for being actuated when receiving electrical power from the power source, a second input for receiving the speed control signal, and an output for transmitting electrical power to the motor brake coil when the speed control signal is below a predetermined value and for automatically stopping the transmission of electrical power when the speed control signal becomes higher than a predetermined value. A manually-operated brake release switch has an input and an output.
