Abstract: A method for operating an elevator having a car, a drive engine, shaft doors, signal receptors, an engine controller and a door controller. Each of the shaft doors is reciprocally opened and closed by an associated active door drive and has one of the signal receptors thereat. The method includes: receiving a requesting signal at one of the signal receptors; responding to the requesting signal by instructing the engine controller to control the drive engine to displace the car to a first position with the car roof adjacent to the shaft door at the floor from which the requesting signal originated when that floor is not the lowermost floor, and when the floor is the lowermost floor to a second position above the lowermost floor; instructing the door controller to control the door drive to actively open the door; and switching the engine controller to an inspection mode.

Abstract: A light modulation device is provided in an elevator installation having an elevator car for performing a method of modulating light in the elevator car. The light modulation device has a modulator that receives a first electrical signal from a control unit of the elevator installation, wherein the modulator, in order to modulate the first electrical signal, controls a lighting device in the elevator car having two or more light-emitting diodes. The lighting device generates a first light signal to encode the first electrical signal, and the modulator switches the light-emitting diodes on and off synchronously or asynchronously and/or adjusts their brightness.

Abstract: In order to provide a reliable interconnection between a wireless mesh network and an external network, more than one border router device may be deployed. A novel load balancing method, and the related system and devices, are disclosed in this invention. By embedding actual traffic load information in the frequency of sending the border router advertisements, automatic traffic load balancing among multiple border routers is realized in 5 the system, without extra signaling overhead or any change to the beacon packet structure.

Abstract: The invention relates a wireless node and to a method for operating the wireless node, wherein the wireless node comprises a controller arranged for communicating wirelessly with at least one further wireless node so as to determine an ability of the wireless node and to create a network, wherein a characteristic of the network depends on the determined ability of the wireless node.

Abstract: Inter-profile commissioning method and apparatus for a network The invention relates to a commissioning apparatus (130, 140) and method for configuring a joining node (150) of a first profile for operation in a network in accordance with a second profile, wherein the commissioning apparatus (130, 140) is arranged to emulate a commissioning process corresponding to the first profile.

Abstract: Master communication device for a token network. The token network comprises a shared communication medium and at least one further master communication device coupled to the shared communication medium, the token network being arranged to pass frames and to execute a poll for master cycle. The master communication device is restricted in executing a poll for master cycle in specified cases especially if another device executed a poll for master for finding a new master communication device on the token network.
