Abstract: A sensor assembly for a fastener assembly comprising a nut and a bolt comprises a sensor unit mounted in a cavity in the nut of the fastener assembly having an internal opening in the internal thread of the nut. The sensor unit comprises an optical flow sensor arranged to capture an image of the external thread of the bolt through the internal opening and to sense relative movement of the external thread of the bolt.

Abstract: A sensor unit mountable on a rotatable element on a platform that is itself movable, and includes an orientation sensor arranged to take measurements that are dependent on the orientation of the sensor unit, a processor arranged to derive a rotational position signal representing the orientation of the rotatable element from the measurements, and a buffer arranged to buffer a series of recent measurements taken by the orientation sensor over a predetermined period of time. The processor derives the rotational position signal making a correction to compensate for the effect of the motion of the platform on the measurements on the basis of the overall series of measurements buffered in the buffer.

Abstract: A sensor unit for a fingerboard latch assembly comprising a latch bracket and a latch rotatably mounted on the latch bracket comprises a sensor arranged to sense the orientation of the latch and a wireless, optical or other communication unit arranged to communicate the orientation of the latch sensed by the sensor. The sensor unit may be mountable on the latch and comprise an orientation sensor arranged to take measurements that are dependent on the orientation of the sensor unit, and a processor arranged to derive an orientation signal representing the orientation of the latch from the measurements, the communication unit being arranged to communicate the orientation signal. A monitoring system receives the sensed orientations from plural sensor units.

Abstract: A valve including a valve body having a bore and a spindle received in the bore, the spindle being actuatable to open and close the valve. A compression gland seal is provided about the spindle for compression between the spindle and the bore. A first seal ring is provided about the spindle at a position spaced along the spindle from the gland seal, and provides a seal between the spindle and the bore of the valve body. A second seal ring is provided about the spindle at a position spaced along the spindle from the gland seal and the first seal ring, and provides a further seal between the spindle and the bore of the valve body.

Abstract: System for connecting a secondary module to a structure having a port. The system includes a tapping connector attachable to the port, and a primary module attachable to the tapping connector, with the secondary module being mountable on the primary module. A collar is receivable over the tapping connector for supporting the primary module on the structure. The collar is attachable to the tapping connector with the primary module being attachable to the collar. A positioner is supported within the collar for fastening the collar to the tapping connector.

Abstract: Connection module for connecting instrumentation equipment to a fluid container. The connection module includes a jointed tapping connector. A connector includes first and second opposed jaw members. The connector includes a receiving space located substantially between the jaw members for receiving a protruded portion of a corresponding connector. The first jaw member includes a hook portion for hooking onto a formation of the protruded portion. The second jaw member includes a locking member or an opening for slideably receiving a locking member. A connector includes a protruded portion configured to be received in a receiving space between first and second opposed jaw members of a corresponding connector. The protruded portion includes a formation for receiving a hook portion of the first jaw member. The protruded portion also includes an opening or a locking member configured to slideably engage with an opening of the second jaw of the corresponding connector.
