Abstract:
A method for controlling current generation in a photovoltaic system having at least one submodule connected to the photovoltaic system. The method includes an alternating switching of the submodule taking place in a changeover time clock pulse between a switching-on state and a bypass switching state, the submodule being interconnected during the switching-on state of the photovoltaic system and being bridged in the bypass switching state. During the bypass switching state, an overall current strength of the photovoltaic system is measured and a setpoint value ascertained from this is stored temporarily. During the switching-on state, a submodule current strength is measured and compared to the setpoint value, and upon a dropping off of the submodule current strength below the setpoint value, a resetting, taking place independently of the switchover time clock pulse, of the submodule to the bypass switching state is carried out.

Abstract:
A method and a system for controlling a wireless sensor network from a user interface coupled to the Internet are provided. A user accesses an Internet-based portal from the user interface and establishes a secure broadband Internet connection between a remote control module coupled to the wireless sensor network and the portal. The connection is established by manually triggering a connection between the remote control module and the portal from the remote control module.
Abstract:
A method and system for controlling a home automation system by voice input provided via a telephone unit. A voice portal server receives a signal transmitted by the telephone unit, processes the signal to interpret the voice input, and generates command signals for controlling a home device in the home automation system based on the interpreted voice input. The voice portal server transmits the command signals over a data network or a telephone network to a home interface for receiving the command signals transmitted by the voice portal server. The home interface controls the home device in accordance with the received command signals.
Abstract:
A mobile security network includes a plurality of primary mobile nodes and at least one secondary mobile node dynamically assigned to be monitored by one of the plurality of primary mobile nodes. The plurality of primary mobile nodes communicate with each other to hand off responsibility for monitoring the at least one secondary mobile node, and monitor a link quality between themselves and any assigned secondary mobile nodes. The network is configured to issue an alarm if a link quality between a secondary mobile node and its assigned primary mobile node falls below a predefined value for a predefined time period, and a link quality between the secondary mobile node and all non-assigned primary mobile nodes does not exceed the predefined link quality.
Abstract:
A method and system to bookmark a location, blog geo-referential information, and process the geo referential information, having a mobile device and a stationary server. The mobile device is configured to generate a waypoint to geographically identify the location, generate a timestamp, fetch and store data associated with the location, and receive a user-provided description regarding at least one of the location and the data associated with the location. The stationary server is configured to receive geo-referential information from the mobile device, the geo-referential information including the waypoint, timestamp, and at least one of the data and user-provided description. The server includes a database to maintain the geo-referential information in a spatially and temporally organized manner, and a processing arrangement to adaptively process the geo-referential information according to at least one of a characteristic and preference of a user.
Abstract:
System for interfacing a device onboard a vehicle and a voice portal server external to the vehicle including a voice communicator and a data communicator situated in the vehicle. The onboard device communicates electronically with the voice communicator and/or the data communicator which in turn are able to communicate wirelessly with a base station. The base station communicates electronically with the voice portal server. A method of providing information to an occupant of a vehicle includes providing a voice communicator, a data communicator, an onboard device, a base station, and a voice portal server. The voice portal server communicates electronically with the base station, the base station communicates wirelessly with the voice communicator and/or the data communicator, and the onboard device communicates electronically with the voice communicator and/or the data communicator. The occupant communicates a request for information via the voice communicator and via the base station to the voice portal server. The voice portal server communicates an information match via the base station and via the data communicator and/or the voice communicator. A vehicle navigation apparatus including a voice communicator, a data communicator, and an onboard device situated in a vehicle. The onboard device is electrically coupled to the voice communicator and the data communicator and communicates wirelessly with a base station which electronically communicates with a voice portal server to provide information to the occupant of the vehicle.
Abstract:
A faceplate including an antenna for receiving navigation signals, a processor electrically coupled to the antenna for determining a position, a display electrically coupled to the processor for displaying navigation information, and at least one input arrangement. The faceplate able to be installed on a front side of a vehicular electronic unit in a dashboard of a vehicle.
