Abstract: A collar assembly for retrofitting a barrier to one or more bollards comprises a barrier and at least one collar adapted to fit around each of bollard. Each collar comprises two or more openings. Each opening is configured to receive a barrier mounting device or a securing element. Each collar has at least one securing element configured to affix the collar to the one or more bollards. Each collar has at least one barrier mounting device configured to attach the barrier to the one or more bollards. The barrier is mounted to each barrier mounting device.

Abstract: A self-diagnosis method and apparatus for measuring results from blood analyzers, the method comprising: generating an acquisition transmittance curve according to the changes in transmittance rate of sample during a sample acquisition process; determining whether there is an anomaly in the acquisition process according to the acquisition transmittance rate curve; if there is no anomaly in the acquisition process, determining that the measurement results of the blood sample are credible; and if there is an anomaly in the acquisition process, determining that there is a doubt about the measured results of the blood samples, the self-diagnosis method and apparatus for measuring results from blood analyzer can improve the accuracy of self-diagnosis of measured results from blood analyzers, and reducing the false positive rate, at the same time, the workload of users in examining and verifying the measured results is reduced, thereby saving on measuring costs.

Abstract: One or more posts of a railing system are held securely in place by a hidden tensioning cable that extends through a cavity of the post along a longitudinal axis and is tensioned to securely fasten the post securely to a surface of a structure. Placement of the tensioning cable through the cavity allows cable receivers to be placed at desired spacing in one or more receiver channels of the post, the cable receivers operable to receive cable rails of the railing system. The receiver channels are oriented transverse the longitudinal axis of the post and are each configured to receive a receiver in to which a cable assembly may be placed.

Abstract: A fence tensioner has a frame which may be rigid or articulated. The tensioner carries on each end thereof a rotatable cylindrical member which is provided with an axial slot to accommodate the profile of a section of fence. The cylindrical member is provided a ratchet and a pawl to lock the cylinder against loosening rotation. The pawl has a square end to lock the ratchet and eliminate any backlash and any slack in the fence members. The frame of the device is articulated so that each end of the device may accommodate the angle of the fence relative to the post. The vinyl fencing fits into the tensioner and locks itself therein as the cylinder rotates.

Abstract: A tensioner device for applying tension to a flexible fence slat includes a bracket assembly having attachment webs for attachment to a fence post and a pair of vertically spaced, horizontally oriented flanges. A tensioning cylinder is mounted for rotation within a pair of apertures provided, respectively, in the horizontally oriented flanges, the tensioning cylinder formed with a through-slot extending longitudinally between a pair of radial flanges. The through-slot has a length substantially equal to a width of the flexible fence slat and adapted to receive one end of the fence slat. A ratchet wheel is formed at one end of the cylinder, between one of the radial flanges and one of the horizontally oriented flanges, and a pawl is pivotably mounted on the adjacent one of the horizontally oriented flanges for engagement with the ratchet so as to permit rotation of the tensioning cylinder in a tensioning direction but to prevent rotation of the tensioning cylinder in an opposite direction.

Abstract: A tool for tightening a plurality of wire lengths that extend between a first bracing location on a first fence support and a second bracing location on a second fence support, the wire lengths defining an axis extending generally parallel to their lengths. The tool includes a body adapted to be transversely inserted between the wire lengths so that the wire lengths pass around the body. The body has at least one seating portion formed on its outer surface for retaining at least one of the wire lengths generally between the ends of the body when the body is inserted between the wire lengths. The body is adapted so that, when inserted between the wire lengths, the body can be selectively rotated about the axis to twist the wire lengths around one another and thereby exert a contracting force on the fence supports.

Abstract: A device for securing one end of fencing material, having a post extending into the ground with its bottom portion having outwardly extending flanges. A wire stretching device including a yoke with a turning rod passing therethrough to which is attached the wiring material comprising the fence, with the turning rod rotated to tighten the fence and a locking device for preventing the rod from counter-rotating. A tensioning device connecting the wire stretching device to the post which has a first and second sleeve with the second sleeve generally disposed within the first sleeve. A resiliant element connected to the second sleeve and adjustably connected to the first sleeve permits the second sleeve to move within the first sleeve. Selectively adjusting the resiliant element the tensioning device maintains the fence at a proper tautness. The device is adaptable to be an electrified fence and to utilize automated equipment in the setting of the posts in the ground.

Abstract: A plurality of rolls of flexible fence cable are wound on a shaft in a drum. The free ends of the cables outside the drum are affixed to a cross bar in spaced parallel relation with each other. The fence cables are unwound through side holes formed in the drum and via a guide member in the drum and are extended via the cross bar to the next-adjacent fence post.
