A surgical generator providing a high-frequency alternating voltage to a surgical instrument. It includes a control unit and a user interface connected thereto. The control unit is configured for controlling the surgical generator based on a set of functions. A signaling interface is provided for optical signaling in a bidirectional manner to and from the remote control. The signaling interface configures the control unit and/or the surgical generator dependent on communication from the remote control. Thereby the surgical generator can be re-configured by limiting certain functions for different fields of application by the remote control. Optical signaling avoids risks of radio transmission. It is an efficient short range communication usable within same room only, providing safety against external access. Thus, re-configuration can be accomplished in a safe and cost-effective manner.

A system and method for determining vehicle position uses light based communication (LBC) signals and a received signal strength indicator (RSSI) to determine the vehicle position. Each vehicle includes a LBC system having an array of transmitting light emitting diodes (LEDs) and an array of receiver photodiodes for transmitting and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes. The controller includes a vehicle communication module that may be executed by a processor to determine the distance. The processor models a first distance between a first transmitting LBC system and a first receiving LBC system, then models a second distance between a second transmitting LBC system and the first receiving LBC system, and then determines the distance between the first vehicle and the second vehicle using trilateration of the first distance and the second distance.

A method for controlling detached lighting units uses source light of a capable flashlight to communicate information. The capable flashlight encodes an ID Tag in modulated light, and the detached lighting units recognize the specific ID Tag and responds, for example by activating and creating illumination. A user can illuminate selected areas by shining the beam of the flashlight on detached lighting units to selectively activate them, and since the detached lighting units only respond to the encoded light, unintended activation is avoided. In addition to the encoded ID Tag, mode information can be included such that the detached lighting units can respond in a number of ways, such as selected periods of activation. Stored ID Tags can be transferred and thus shared using the same modulated light. ID Tags can be randomly re-assigned, and the new value shared among other flashlights and detached lighting units, creating a coordinated set.

A system for simultaneous wireless control of lights and motorized window coverings that include sheer interior shade material and blackout exterior shade material. The system includes a voice activation module which is wirelessly connected to a plurality of motorized window coverings using a first transceiver and a first wireless protocol and a plurality of lights using a second transceiver and a second wireless protocol. The voice activation module is preprogrammed to listen for a trigger phrase followed by any one of a number commands. Once the trigger phrase and a command are recognized, the wireless device transmits an over-the-air signal to the plurality of motorized window coverings and lights. The wireless device also includes an indicator that provides a visual or audible indication to the user that the trigger phrase, and/or a command has been recognized.

A system provides an audible signal to the user of the system before a control or function is activated by the user. In one embodiment, a remote control can be used with an apparatus, such as a set-top box. When the user places an object near a control of the remote control, a control or function associated with the control may be announced to the user before activating the control. The system can include an apparatus configured to be operated at least in part from a remote control that includes a plurality of controls including a first control. The apparatus includes a control module configured to receive an identification signal from the remote control, wherein the identification signal corresponds to the control, determine a state of the apparatus, determine a function to which the control corresponds, and send another identification signal to an audio system.

A transducer is described especially for use in providing acoustic transmission in a borehole. The transducer includes a multiple number of magnetic circuit gaps and electrical windings that have been found to provide the power necessary for acoustic operation in a borehole while still meeting the stringent dimensional criteria necessitated by boreholes. Various embodiments conforming to the design are described. Moreover, the invention includes transition and reflector sections, as well as a directional coupler and resonator arrangement particularly adapted for borehole acoustic communication.An acoustic communication system is described especially designed for use in providing acoustic transmission of information in a borehole. The communication system comprises a surface transceiver and at least one downhole transceiver. The surface transceiver operates in conjunction with a host computer that sends commands to the downhole transceiver. Subsequently, the downhole transceiver transmits encoded data from subsurface, borehole sensors to the surface transceiver. The preferred embodiment uses Minimum Shift Keying (MSK) modulation for both transmitting commands to the downhole unit and for transmitting data to the surface transceiver. To facilitate operation of a coherent communication system in the inhospitable environment of a borehole, the acoustic channel is characterized to enable the system to choose the best possible frequency and bandwidth for communication transmission. Additionally, the system achieves synchronous operation by transmitting synchronization signals between the downhole transceiver and the surface transceiver prior to the units exchanging commands and data.
摘要:
A method for remotely monitoring conditions such as carbon monoxide for methane gas concentration, longwall roof support pressure, machine parameters or uncut coal, trona or potash layer thickness in a natural resource mining system such as a longwall or continuous mine system. The method utilizes a plurality of sensors connected to low magnetic moment transmitters, e.g. 0.1 ATM.sup.2, or high magnetic moment transmitters, e.g. 2.5 ATM.sup.2, that transmit collected data during multiple short burst transmission periods. Prior to transmission, the data is converted to a digital word format. An algorithm in the transmitter microcomputer ensures that random time intervals exist between data transmission bursts thus preventing a data transmission clash at the central receiver. A microcomputer algorithm in the central receiver protects against data contention caused by simultaneous transmission from several sensors. The data is transmitted to the central receiver either through a natural waveguide pathway or through a utility conductor that is magnetically coupled to the transmitter and central receiver by properly oriented electrically short magnetic dipole antennas. The method can be used, for example, to automatically control the positioning of a plurality of longwall roof supports or to transmit data from a longwall drillhead, along the drill rod, to the central receiver. Data can be communicated between a remote location and a surface area by utilizing a system of repeaters inductively coupled to a utility conductor. Use of the repeater system permits operation of mining machines from a surface computer.
