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 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.

In a particular illustrative embodiment of the present invention, a retractable safety banner system and method are disclosed having a retractable safety banner, a reel housing and a reel. The reel winds in and contains the wound up safety banner inside of the reel housing. The safety banner is reeled into and out of the reel housing through an organizing guide that is formed in the reel housing. The organizing guide forces the reeled out safety banner's flags and strap into longitudinal alignment on the reel so that the safety banner is restored to its original configuration when wound back into the reel housing after deployment. The safety banner includes but is not limited to longitudinal strap with a plurality of safety flags attached to the strap and so that the flags hang at a substantially perpendicular angle from the strap forming the safety banner when the safety banner is deployed.

A method for monitoring operation of an archery bow includes attaching an apparatus to a bow cord. The apparatus includes a processor, a monitoring device electrically coupled with the processor, a wireless communication module electrically coupled with the processor, and a power supply electrically coupled with each of the processor and the wireless communication module. The method further includes detecting, by the monitoring device, a tension of the bow cord. The method also includes generating, by the processor and based upon the detected tension of the bow cord, data concerning tension of the bow cord. The method further includes wirelessly transmitting, by the wireless communication module, the data to a remote computing device. The method also includes receiving, by the remote computing device, the data. The method also includes presenting, by the remote computing device and based upon the data, information to a user reflecting the detected tension.

A cargo restraint system includes a body, a first connecting end and a second connecting end on opposing sides of the body, wherein the first and second connecting ends are coupled to a securing member which is used to restrain the cargo. One or more load sensors are coupled to the first connecting end and/or the second connecting end. A controller is coupled to the one or more load sensors. The controller is configured to receive tension information from the one or more load sensors. The controller includes a transmitter capable of transmitting the tension information to a remote device. The controller may include a database to store the information.

A tensioning device includes a housing, a drive member, an inner sleeve and a driven member. The housing includes a first attachment feature. The driven member includes a second attachment feature. The inner sleeve is disposed at least partially in the housing and is rotatably coupled with the housing. The drive member is rotatably coupled with the housing and is operably coupled with the inner sleeve such that rotation of the drive member facilitates rotation of the inner sleeve. The driven member is movable with respect to the guide member between a retracted position and an extended position along a centerline.

The invention relates to a load holder (1, 200) for a suspension system for suspending loads, comprising fastening means (30, 30′) for releasably fastening a suspension module (10) to and/or a suspension module (10) on a first end of the load holder (1, 200), as well as a load bearing device (60) at a second end of the load holder (1, 200), which faces away from the first end along a longitudinal direction (L) of the load holder (1, 200). In order to reduce the risk of falling loads when using the suspension system and to simply the correct set-up of the suspension system, the load holder (1, 200) further comprises a levelling module (20, 20′) for adjusting a length (L1, L2) of the load holder (1, 200) in the longitudinal direction (L) and a measurement module (40) for measuring a tensile load between the load bearing device (60) and the first end.

A cargo restraint system includes a body, a first connecting end and a second connecting end on opposing sides of the body, wherein the first and second connecting ends are coupled to a securing member which is used to restrain the cargo. One or more load sensors are coupled to the first connecting end and/or the second connecting end. A controller is coupled to the one or more load sensors. The controller is configured to receive tension information from the one or more load sensors. The controller includes a transmitter capable of transmitting the tension information to a remote device. The controller may include a database to store the information.

In various example embodiments, devices, systems, and methods for a waist measuring belt are provided. An example waist measuring belt is made up of a belt buckle frame with attachments for a belt strap. The belt further includes a position measuring module coupled to the belt buckle frame that measures an attachment position of a second end of the belt strap to the belt buckle frame. The belt also includes a tension measuring module coupled to the belt buckle frame that measures a tension through the belt buckle frame and the belt strap. A memory and a wireless communication module attached to the belt may be used to store measurements and communicate with a mobile device or server. In various embodiments, estimated user waist sizes over time using measured values and belt-specific data may be used to estimate a user's waist size and generate a waist size history.
