Abstract: A system and/or method that establishes a proximity environment with respect to an elevator and detecting a position of a user device within the proximity environment is provided. Further the system and method determines a source floor and a destination floor respective to the user device and generating an elevator call to the elevator in accordance with the source floor and the destination floor.

Abstract: An electrical system (2) comprises a battery (26) for storing electrical energy; a battery monitoring device (22) which is configured for determining a numerical value representing the charging state of the battery (26) by setting an initial numerical value representing the charging state of the battery (26); and repeatedly determining a current operational state of the electrical system (2) and a time period (T1-T10) for which said current operational state is active; calculating a change of the charging state of the battery (26) as a function of the determined current operational state of the electrical system (2) and the time period (T1-T10) for which said current operational state is active; and updating the numerical value representing the charging state of the battery (26) by adding or subtracting the calculated change of the charging state to/from the numerical value.

Abstract: Embodiments are directed to receiving, by a demand entering device configured to receive an elevator destination command, a request for at least one of: statistical data regarding use of at least one elevator, and field data in connection with a field service, maintenance, repair, or installation activity associated with the at least one elevator, and obtaining, by the demand entering device, at least one of the statistical data and the field data in response to the request.

Abstract: In accordance with a preferred embodiment of the present invention, an electronic safety system for elevators for preventing unsafe elevator operation has a central controller which monitors a variety of sensors, contacts, and switches over an electronic safety bus. A plurality of bus nodes are distributed throughout the elevator system and are in constant communication with the central controller over the safety bus. The bus nodes interface with sensors, switches, contacts, detectors, components, and other safety equipment of the elevator system at each location and provide status information back to the controller. The controller consists of a microprocessor board with an input/output port in communication with the safety bus and bus nodes. Upon sensing an unsafe condition, the controller sends control signals to an elevator control system and a drive and brake system to arrest the elevator car in a safe manner.
