Abstract: A method of determining a configuration state of an I/O module connected to a fieldbus controller is disclosed, the method comprising the steps of receiving from the I/O module a key ID, comparing the key ID with at least one key ID stored on the fieldbus controller, and configuring the I/O module when the received key ID does not correspond to the at least one stored key ID stored. Further, a circuit for configuring a digital input of a fieldbus controller as either a PNP input or an NPN input is provided comprising a control circuit including a reference input, a first selection input, and a control output. The circuit also comprises a data circuit including a second selection input electrically connected to the control output, a data input electrically coupled to the digital input, and a data output.

Abstract: A method for operating a fieldbus controller (2) having a plurality of I/O modules (4) is provided, the fieldbus controller (2) being coupled to a valve assembly (6) via the plurality of I/O modules (4). The method includes providing a user interface (8) for wirelessly operating the fieldbus controller (2), wherein providing the user interface (8) includes: providing a configuration interface (14) for configuring an operating mode of the plurality of I/O modules (4); providing a monitor interface (16) for reading status information from the plurality of I/O modules (4); and providing a control interface (18) for controlling a state of the plurality of I/O modules (4), the state of the plurality of I/O modules affecting a state of the valve assembly (6).

Abstract: A hanger system for temporarily hanging a valve bank on a vertical mounting face of a substrate. The hanger system includes one or more hanger brackets for attaching to the vertical mounting face. The valve bank has one or more mounting studs protruding from an underside surface of the valve bank, in which the mounting studs are configured to couple with the hanger brackets for temporarily hanging the valve bank on the mounting face with the underside surface facing toward the mounting face. The mounting studs and hanger brackets are configured to cooperate with each other to allow the valve bank to be secured in multiple different orientations against the mounting face, thereby facilitating fixedly mounting the valve bank to the mounting face with one or more fasteners that are received through corresponding fastening receivers in the valve bank.

Abstract: A cover access notification device is employed with a utility meter box having a cover. The device is operable to detect when an impermissible open condition has occurred, for example, if an intruder breaks into a meter box. If a tampered condition is sensed, the device transmits a signal through a smart grid network which can be received by a revenue protection system that in turn monitors tampering of a utility meter.

Abstract: The embodiments described and claimed herein are improved wheelchair passenger securement systems and stations. In particular, one embodiment described and claimed herein is a drop-in system comprising a barrier module and a wall-side module, which incorporate three separate restraint devices which are configured to secure a wheelchair at three separate attachment points. The system can optionally include a moveable excursion barrier or a pull-mechanism to pre-tension at least one of the restraint devices the wheelchair securements. In a simpler embodiment, three restraint devices, such as retractors, are provided for attachment to the vehicle surfaces or structures in, for example, a generally right-triangular configuration.

Abstract: The inventions described and claimed herein are systems or components for an automated rear-facing wheelchair passenger station and include a forward excursion barrier for preventing forward movement of a wheelchair, lateral excursion barriers for preventing undesired movement of a wheelchair, and an electro-pneumatic control system.

Abstract: A clamp including kinetic energy control. The clamp includes a self-compensating, non-adjustable hydraulic damper having kinetic energy absorption, such as a shock absorber.

Abstract: The present invention provides an electric locking device which has a simple structure, with which an operating time can be saved, and which has a sufficient clamping force required for operation. To a camshaft coupled to an electric motor through a speed reducing mechanism, a first cam and a second cam conjugate with each other are coupled. The first cam drives an arm driving rod in a clamping direction and the second cam drives the arm driving rod in a returning direction. Rotational motions of the first and second cams are converted into linear motions in the same direction by first and second cam contacting members supported by the arm driving rod. The arm driving rod drives a clamping arm to cause the arm to carry out a clamping operation. A cam face is provided as to move the clamping arm at a high speed until the arm reaches a vicinity of an end and to move the arm at a lower speed after the arm has reached the vicinity of the end.
