A cam assembly for an archery bow is provided. The cam assembly includes a cam body and an anchoring lug. The cam body defines a pivot axis and a groove circumferentially routed at least partially around the pivot axis. The anchoring lug is coupled with the cam body and includes a force sensor. The anchoring lug is offset from the pivot axis and is configured to facilitate attachment of a bow cord thereto. The force sensor is configured to facilitate detection of a tension on the bow cord as a function of a force imparted to the force sensor from the bow cord. An archery bow is also provided.

The present invention discloses a tunnel toxic-and-harmful-gas deep-hole detection device and method. The tunnel toxic-and-harmful-gas deep-hole detection device comprises a detector, a lifter, and a control terminal, which are sequentially connected. The control terminal controls the lifter to achieve movement of the lifter. The detector comprises a shell with a hollow interior and two opened ends. An air inlet is formed in the outer wall of the shell. A gas detector and a gas sampler are arranged in the shell, and the air inlet is located therebetween. The tunnel toxic-and-harmful-gas deep-hole detection method comprises two steps, namely a gas detection step and a gas sampling step. The present invention can effectively detect components and concentrations of various gases in a drill hole, wherein the detection data is real-time and accurate.

A resistance-band exercise monitoring device includes a first force sensor that senses a first force applied to a first resistance band, a second force sensor that senses a second force applied to a second resistance band, a single electronics module with a single transceiver for wirelessly communicating with a remote device, and a flexible strap physically coupling with the first and second resistance bands. The flexible strap has conductive pathways electrically coupling the force sensors to the single electronics module. The single electronics module communicates values indicative of the first and second forces to the remote device via the single transceiver. The flexible strap does not stretch and protects the conductive pathways from excessive stress. The resistance-band exercise monitoring device may be configured in multiple ways to perform a wide variety of exercises.

A method can include receiving information associated with a conveyance of equipment in a borehole via a cable. The method may further include determining cable tension values based at least in part on a model and at least a portion of the information and conveying the equipment in the borehole via the cable; acquiring a cable tension value via one or more sensors. The method may further include comparing the acquired cable tension value to at least one of the determined cable tension values and, based at least in part on the comparing, setting a cable tension limit for further conveying of the equipment in the borehole via the cable.

A method of checking belt tension of a belt extending between two or more pulleys includes providing a reference indicator defining a reference position relative to the upper surface of the belt in an undeflected state. A force/probe assembly is provided and has measurement markings. The distal end of the force/probe assembly is positioned on the upper surface of the belt at a midpoint of the span. A force is applied generally perpendicular to the upper surface of the belt using the force/probe assembly. The belt may be deflected a predetermined distance, as determined by using the measurement markings, and the force applied is measured, or a force is applied to the belt until the force is equal to a predetermined force, and the deflection of the belt is measured using the measurement markings. The belt tension is determined based on the force and distance during the deflecting step.

A conveyor system that includes a sprocket, a conveyor element, a sensor, a tensioning system, and an electronic processor. The conveyor element is coupled to the sprocket to move around the sprocket. The sensor is positioned adjacent to the sprocket and configured to generate an output signal indicative of a detection of the conveyor element. The electronic processor is coupled to the sensor and to the tensioning system. The electronic processor is configured to receive the output signal from the sensor, estimate a trajectory of the conveyor element based on the output signal, determine a value for slack distance based on the estimated trajectory of the conveyor element, and control the tensioning system based on the value for slack distance.

A self-diagnosing sensor system for a vehicle is provided. The vehicle has a bumper with fascia material. The sensor system includes an elongated, deflectable cable disposed in the bumper generally adjacent to the fascia material. A tensioning and sensing unit is coupled to each end of the cable and fixed to the vehicle. Each unit includes a tension sensor electrically connected with an ECU of the vehicle such that the ECU receives signals from the tension sensors regarding tension in the cable, indicative of 1) whether the bumper has been impacted based on deflection of the cable from a sensing position, or 2) whether damage to the cable or a tensioning and sensing unit has occurred.

Apparatus for monitoring performance of tie down straps are disclosed. A tie down strap is attached to a strap monitor. The strap monitor continuously monitors the physical parameters of the tie down strap. Further, an electronic device communicatively coupled to the strap monitor receives physical parameters of the tie down strap from the strap monitor to determine performance of the tie down strap. Furthermore, upon determining any issues with the performance of the tie down strap, a user is alerted of the issue by the electronic device.
