Abstract: Provided is a gas sensor system with a gas sensor, and a microprocessor programmed to control the gas sensor with at least two operational modes. The first operational mode controls the gas sensor from a baseline level through analyte detection. Upon initiation of the recovery phase after analyte withdrawal, the gas sensor system switches to the second operational mode, which changes conditions of the gas sensor to (i) accelerate removal of the analyte from the gas sensor and (ii) accelerate recovery of the gas sensor output towards the baseline level. When no further analyte is detected, the gas sensor switches back to the first operational mode or to an additional operational mode to complete recovery.

Abstract: This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

Abstract: Apparatus for visually indicating a loose wheel nut on a motor vehicle has a first ring for engaging a first wheel nut so as to be rotatable therewith and a second ring for engaging a second wheel nut adjacent to the first wheel nut so as to be rotatable therewith. The first ring has a first pointer for indicating a start position of the first ring, and the second ring has a second pointer for indicating a start position of the second ring. A resiliently flexible elongate member interconnects the first and second rings. The elongate member is configured to curve in at least two directions and has a first end portion connected to the first ring and an opposed second end portion connected to the second ring. In use, any loosening rotation of the first wheel nut will cause the first ring and is pointer to rotate therewith, thereby providing a visual indication of a loosening of the first wheel nut.

Abstract: The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.

Abstract: An apparatus (10) for visually indicating a loose wheel nut (57) on a wheel of a motor vehicle has a plurality of wheel nut engaging members (12, 14, 16, 18, 20). Each wheel nut engaging member is rotatable with a respective wheel nut to which it is engaged and has a pointer (26) for indicating a start position of the wheel nut engaging member. Any two adjacent wheel nut engaging members of the plurality are interconnected by an elongate member (28) which is resiliently flexible so as to define an endless configuration of spaced apart but interconnected wheel nut engaging members. In use, any loosening rotation of a first wheel nut (57) will cause the engaging member (12) which engages that wheel nut and its pointer (26) to rotate therewith, thereby providing a visual indication of a loosening of that wheel nut.

Abstract: This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.

Abstract: This disclosure relates to medical tubing installation detection. In certain aspects, a method is performed by a data processing apparatus. The method includes detecting that a tube is incorrectly installed on a drug delivery device by providing an instruction for a motor of the drug delivery device to pump a drug and receiving, after a period of time has passed since providing the instruction for the motor of the drug delivery device to pump the drug, a signal from a fluid detector connected to the tube, the signal indicating an absence of fluid in the tube.
