A tethered unmanned aerial vehicle (“UAV”) may be outfitted with a sensor payload for data gathering. The tethered UAV may be tethered to a ground station for constricting the flight space of the UAV while also providing the option for power delivery and/or bidirectional communications. The tethered UAV's flight path may be extended by introducing one or more secondary UAVs that cooperate to extend the horizontal flight path of a primary UAV. The ground station, which may be coupled with the tethered aerial vehicle, may comprise a listening switch configured to determine a condition of the tether such that the supply of power to the tether may be terminated when tether damage or a tether severance is detected.

The present invention provides a home security system that includes a home security controller for collecting monitor data from various crime prevention and disaster prevention sensors installed in a home via a home network and notifying the portable terminal when a state of emergency occurs. The home security controller also enables devices in the home to be operated through remote control signals via an external network. The home security system further includes a portable terminal capable of connecting to the external network and having fingerprint data inputting means mounted on the body of the portable terminal for inputting fingerprints used for authentication. The fingerprint data inputting means has an assigned ID number. The home security system further includes a security center server having fingerprint authenticating means for receiving fingerprint data from the portable terminal via the external network and authenticating the fingerprint data through comparisons with registered fingerprint data. The fingerprint authenticating means completes authentication by checking the assigned ID number of the fingerprint data inputting means and matching the received fingerprint data with fingerprint data registered in association with the ID number. The security center server allows a connection between the portable terminal and the home security controller and controls bi-directional communications between the two after the security center server has completed authentication, enabling the portable terminal to receive monitor data from and transmit remote control signals to the home security controller via the external network.

Bi-directional communications via TCP ("Transmission Control Protocol")/IP ("Internet Protocol") between an HTML client program (i.e. "web browser") and the linked or embedded HTML server ("Hypertext Markup Language") of a Building Automation System ("BAS") are used to provide an authorized user with access to the interactive graphical panels of the BAS allowing the user to, for instance, monitor, control, configure and interact with the BAS or multiple BAS's.

A repeater mediates traffic between a network transceiver and a user transceiver in a wireless communication system. The repeater comprises a network unit that maintains a network link with the network transceiver, a user unit that maintains a user link with the user transceiver, a two-way communication pathway between the network unit and the user unit; that facilitate the communication of signals between the network transceiver and the user transceiver in autonomous repeater hops between the network transceiver and the network unit, between the user transceiver and the user unit, and between the network unit and the user unit, and a gain controller that compensates for propagation losses between the network unit and user unit alone.

A lighting system for areal illumination is disclosed which includes a remote driver and a plurality of fixtures including luminaires, control devices, and/or standalone sensors. The luminaires include a light source whose output light level can be adjusted, a light sensor co-located therewith adapted to measure light received from adjacent fixtures, and a microcontroller capable of transmitting the output of the light sensor over wires to the remote driver. The remote driver is capable of bidirectional communication with the luminaires and provides independently controllable power for the light sources of the luminaires. A method of commissioning a lighting system is also disclosed which includes installing a plurality of luminaires above the area to be illuminated, causing a light source co-located with each luminaire to emit a signal, detecting the signal at light sensors co-located with each luminaire, converting the signals obtained by the light sensors into distance measurements between luminaires, creating a map recording the relative location of luminaires, and assigning luminaires to groups based on their relative locations in the map. A movable orb region large enough to containing a plurality of luminaires can also be defined and the light levels of individual luminaires can be set according to a defined mathematical function of their location within the orb region, where the defined mathematical function sets light levels which vary from the center to the periphery of said orb region.

The present invention contemplates a choke control system that provides for local and off-site monitoring and control of the annulus flow pressure of a well. The choke control system includes a choke manifold connected to at least one choke and its associated actuator; a variety of instrumental drilling sensors, pump stroke counter switches, and choke position indicators; a local choke and hydraulic pressure control console; and a programmable controller in communication with the local choke and hydraulic pressure control console. The programmable controller handles the logical operations of the choke control system, including processing instrument measurements and operator input data to produce control signals for operating the choke, the choke actuator and the various valves associated with the choke manifold. The programmable controller is typically either an electronic digital computer and/or a programmable logic controller (PLC). The present invention further contemplates the two-way communication between the choke control system and the Internet via a satellite linkage.

A personal portable integrator is used to integrate the services of an arbitrary audio delivery device such as an MP3, CD, DVD, radio, or other media player, with the services of an arbitrary two-way communication device such as a mobile phone, or a two-way radio such as a walkie talkie, citizen band radio (e.g. CB), HAM radio, marine or aviation radio, and the like. The portable integrator receives and provides input and output signals from both the audio delivery device and the two-way communication device, thereby enabling a user to listen to music or other audio material and receive and place phone calls on a mobile phone simultaneously. The portable integrator provides these services by switching between the audio and communication devices, mixing signals received therefrom, and optionally enabling a user to reduce the volume or mute the signals as desired.

A security system architecture including bidirectional communication between a sensor control device and one or more sensor devices coupled to the controller is provided.
