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.

A load indicator for use with a fall protection apparatus having a line and a connector for connecting to a user includes a housing having a pass-through opening and a covered indicator region. At least a portion of the housing is configured for connecting to the line. The load indicator also includes a shear pin supported by the housing and extending across the pass-through opening, and a saddle extending across at least a portion of the pass-through opening and supported by at least a portion of the shear pin. The saddle is configured for connecting to at least a portion of the connector. The saddle is movable relative to the housing between a first position and a second position when a force exceeding a predetermined threshold value is applied on the saddle causing the shear pin to shear or break. At least a portion of the indicator region is uncovered in the second position of the saddle when the shear pin shears or breaks.

The present invention relates to a system for monitoring tension forces of tendons in post-tensioning that accurately measures the tension forces of the tendons and/or controls the tension forces introduced into the tendons through a main server, thereby allowing the tension forces to be applied uniformly to the tendons.

According to the present invention, there is provided the system for monitoring tension forces of tendons disposed inside a concrete structure in post-tensioning, the system including: a hydraulic jack coupled to one tendon at one end of the concrete structure to apply the tension force to the tendon by means of the forward movement of a piston; a hydraulic pump connected to the hydraulic jack by means of a hydraulic pressure supply pipe to supply a hydraulic pressure to the hydraulic jack; a digital elongation length measurement sensor disposed on the hydraulic jack to measure the elongation length of the piston; a measurement unit having a data logger adapted to receive and store the elongation length data measured by the digital elongation length measurement sensor and to send the elongation length data to a main server; a digital pressure measurement sensor disposed on the hydraulic pressure supply pipe of the hydraulic pump; and a control module adapted to receive the elongation length data from the data logger or the main server, calculate the tension force, compensate for the coefficient of elasticity of the tendon according to the ratio of the real-time elongation length data to the pressure data, and compensate for the tension force calculated.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example system for detecting disengagement of a surgical tool, includes an end effector connected to and driven by cables of a tool driver, sensors configured to detect forces associated with the cables, and one or more processors. The one or more processors identify cable tensions derived from forces detected by the sensors, compare the tension to a threshold tension value, calculate a velocity norm value based on a vector including the velocity value for each of the cables, compare the velocity norm value to a statistic velocity threshold, and identify a disengagement of at least one of the plurality of cables based on the first comparison and the second comparison.

An apparatus for emulating a variety of string instruments with a variety of configurations in order to measure the resulting, actual tension of a string on that instrument. The tension may be measured in real-time.

In general, the present invention has to do with a UV reference indicator calibrated to represent the color or shade of a UV reactive dye after a predetermined exposure time to a UV radiation source.

The present invention relates generally to the field of fishing drag scales. More specifically, the present invention relates to a fishing reel drag set device that is comprised of a body, an upper and lower housing, two eyelets and a power supply. The device may be adjustable or non-adjustable (i.e., static), wherein the adjustable version allots the user multiple tension settings for the line and the static version has only one tension setting. Other visual and audible elements such as colored LEDs, a speaker relay and visual and audio indicators are provided to help identify if the drag in the fishing line is too heavy or too light. Accordingly, the device can be applied to any fishing rod and fishing line to aid a fisherman in using a desired drag setting when attempting to catch a fish.

A pet collar has an adjustable length strap and a buckle. The buckle has a receiver and a clip releasably coupled to the receiver. The receiver includes a catch portion coupleable to the clip and a tension indicator portion. The tension indicator portion has two side walls defining a shuttle channel. Each side wall has a top surface having a first mark, a second mark, a third mark, and a fourth mark which have color coding. The shuttle channel is configured to slidably receive a reciprocating tensioning shuttle therein. The tensioning shuttle includes two side wall and a compression spring. Each side wall also includes a top flange overlaying the receiver side walls that includes a first viewing window and a second viewing window. The viewing windows alignment with the underlying marks indicated the tension of the collar upon the pet.

Belt tensioning monitoring device for monitoring the belt tensioning of a belt of a belt drive system including a driving pulley and a driven pulley rotated by the driving pulley by way of the belt. The belt tensioning monitoring device is configured to determine the belt slip effect with at least two marks each located on one of the pulleys and sensors each configured to detect one mark and to send a signal to an electronic control unit.

A cable puller includes a frame, a capstan mounted on the frame around which a pulling rope is wrapped, and a sensor configured to measure the distance the pulling rope travels relative to the frame. The sensor may be a Hall effect sensor and/or an optical sensor.
