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.

Fastener assembly sensor unit

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.

Sensor for a rotatable element

A wireless network comprises nodes, including routers having a tree-shaped communication topology and end devices, communicate in accordance a network protocol, wherein the routers transmit beacons in respective timeslots within a periodic beaconing interval, passively scan for messages, and, in response to receiving a message, transmit an acknowledgement thereof the received message. An end device that has a message that is pending transmission, passively scans for beacons transmitted from any router; and in response thereto, transmits the message, and passively scans for an acknowledgement, repeating those steps if no acknowledgement is received. This provides responsivity in an environment having rapidly changing propagation paths. To reduce power consumption, the end devices do not passively scan for beacons except when they have a message that is pending transmission, and also at predetermined times for reception of a downstream message. When radio silence is required, the routers do not transmit beacons.

Beaconed wireless network

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.

Sensor for a fingerboard latch assembly

A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.

Molding method using two different resins and a membrane

Apparatus for drying trays with side walls such as are used in the food industry comprises a conveyor for passing the trays along a path of travel disposed along which is a drying apparatus for directing jets of air, which may be at ambient temperature, onto the tray surfaces. The drying apparatus comprises a nozzle arranged such that in its normal position its outlet is close to the base of the tray to direct air onto the base and which is displaceable from its normal position by the side walls of trays passing along the path, the nozzle returning to its normal position when out of contact with the side walls. The drying apparatus may be used alone or in combination with a tray washing apparatus comprising a tank for containing washing fluid which has a first end for receiving unwashed trays and a second end for receiving washed trays, path of travel defined for the trays through the tank, and a series of rotatable brushes arranged along the path for engaging the tray surfaces with brushing bristles so as to brush wash the tray surfaces by agitation of the washing fluid in contact therewith and simultaneously to propel the trays along the path from the first end to the second end. Alternatively the washing apparatus may be used alone.
