Abstract: A status sensing and reporting interface is provided. The interface includes one of an interface port or an adapter. Each of the interface port and adapter include: a body; a coupling circuit positioned within the body and configured to sense an electrical signal flowing through the status sensing interface; and an electrical parameter sensing circuit positioned within the body and configured to sense a parameter of the electrical signal flowing through the status sensing interface and a physical condition of the connection between the status sensing interface and a connector to which the status sensing interface is operatively coupled.

Abstract: An apparatus for presenting a time-variant information element in a vehicle, which has a steering wheel (1602), comprises one or more remotely and individually controllable tactile pads (1620), which produce a tactile sensation in response to a respective pad output signal, which is produced by a controller (CTRL). The tactile pads are positioned or adapted to be positioned on the steering wheel (1602) or proximate to it, such that they can be touched by at least one hand (1610,1612) of the vehicle driver while driving the vehicle. The apparatus further comprises means for determining the time-variant information element to be presented and for applying the determined time-variant information element to the controller and means for encoding the determined time-variant information element by the controller into temporal variations of the one or more pad output signals.

Abstract: A safety device is provided that can be connected with a technical device and an associated emergency activation apparatus. The safety device includes a rail. The rail and emergency activation apparatus are fashioned such that the emergency activation apparatus can be attached to the rail and be shifted thereon. A test signal can be output by the rail that can be received by an emergency activation apparatus attached thereto independent of its shift position. A response signal can be output by the emergency activation apparatus that can be received by the rail independent of the shift position emergency activation apparatus. The safety device is fashioned such that a signal can be emitted to the technical device dependent on the receipt of the response signal. Via the signal, an emergency measure can be triggered, for example an emergency disconnection of the technical device such as an E-stop or, respectively, dead-man's function.

Abstract: In a boiling water reactor controlling each control rod hydraulically by driving a solenoid valve, the control system comprises an operation control means 41 having a duplicated data processing unit for generating sequence patterns based on the timing of the driving sequence based on the control information provided manually, a transmission control means 42 for creating a command word corresponding to each control rod being controlled based on said sequence pattern, and mutually communicating each command word between duplicated data processing units and computing the AND logic of said data within a predetermined time difference, and when the computed result coincide, transmitting the selected command word serially; a transmission unit 32 for receiving said command word and performing protocol conversion thereto, and transmitting the same to a plurality of transmission branch units positioned downstream as the control command; and a solenoid valve drive circuit 31 for driving the control rod drive unit corres

Abstract: A fire alarm system provided with a fire receiver (1) to which a plurality of fire sensors and controlled apparatuses are connected. The fire receiver (1) comprises a LAN interface (11) for connecting with other fire receivers. When a fire sensor issues an alarm, the fire receiver transmits the fire information over the LAN together with a group number set in advance, and displays (12) only the fire information of the same group number when the fire receiver receives fire information transmitted from the other fire receivers via the LAN. Thus, even is a plurality of fire receivers are used in a large building divided into ridge sections, fire information can be shared without causing disorder.

Abstract: A method and apparatus for communicating between Customer Premises Equipment, (CPE) alarm sensing devices, and alarm monitoring stations. The sensing devices communicate with an end office switch by transmitting a message, such as a string of Dual-Tone Multi-Frequency, (DTMF) digits to that switch. At the switch, the message is processed and a determination is made which of a plurality of alarm monitoring stations should receive the alarm indication. One or more data packets are sent to the selected alarm monitoring stations with the packets identifying the source of the alarm indication, and the type of alarm indication. Advantageously, the packetized communication between the end office switch and the alarm monitoring system allows a high volume of alarm indications to be sent to an alarm monitoring station, because individual telephone connections are not required for each such alarm message.

Abstract: A building alarm system includes addressable notification appliances connected to a system controller, with each notification appliance having a status indicator and an alarm indicator. The status indicator, such as an LED, provides for system test modes that avoid disruption of building occupants. To test the alarm system, the system controller selects which notification appliances to operate in response to a test alarm input and communicates to each selected appliance an instruction to operate its associated status indicator without operating its associated audible or flashing visible alarm indicators. In a troubleshooting mode, the system controller polls each of the notification appliances and receives an answer in response to the poll from any of the appliances. The controller operates the LED indicators of those appliances which answer the poll.

Abstract: The invention concerns a process and a device for the recognition of screws used in extruders or metering devices. In order to create a process that excludes the possibility that mixtures of granulates or powders with incorrect mixing ratios occur through installation of inappropriate screw shafts in metering screws, the screws are coded and the code is electronically identifiable.

Abstract: In a communication system such as a fire detection system, individual addressable devices determine their addresses from address interface modules at the device locations. An interface module includes wire connectors for receiving system wires and a device connector. The interface module also includes jumper wires which serve as a readable address identifier adapted to be programmed to an address with installation of the module and to be subsequently read by the addressable device.

Abstract: A fire detector assembly comprises a base (1) and a sensor (5) adapted to fit the base. The base (1) is provided with passive means, such as pins (6) or contacts arranged in a pattern to represent an address of the detector. When the sensor (5) is fitted to the base (1), reading means in the sensor reads the address code and thereby conditions the sensor to receive appropriate signals from a control unit.

Abstract: In an alarm control system for protecting a premises, a four conductor bus line leading from a master control station is extended about the interior perimeter of the premises. Sensors positioned near each port of entry to be monitored are connected in parallel relationship to the bus line, as is at least one remote station for manually arming, disarming or activating the system. Each sensor comprises a biased reel carrying line secured to window, door, screen, or the like. Disturbance of a sensor causes a magnetically responsive switch therein to generate a pulse triggering circuitry within the control station to activate the desired alarm device for a predetermined period of time. The system then resets automatically to an armed or ready condition to continue protecting the premises against subsequent intrusions. Preferably, the lines in the sensors are of a thermoplastic material so that the system is also activated by abnormally high temperature in the event of fire.
