    Abstract: A connection structure of a diaphragm pressure gauge contains: a holder, a coupling sleeve, a disc, a curved abutting bar, a fixing element, a case, a screw element, a circular film, and a defining element. The holder is connected to the coupling sleeve, multiple spaced ribs of the holder extend out of the coupling sleeve, and the holder includes the multiple spaced ribs. One of the multiple spaced ribs has at least one spaced protrusion, the disc includes at least one first locating orifice, the curved abutting bar includes a second locating orifice, and the at least one first locating orifice is fitted with the second locating orifice. The curved abutting bar abuts against the fixing element, and the defining element, the circular film and the screw element are connected below the fixing element to produce the diaphragm pressure gauge. The case is covered on the diaphragm pressure gauge.

    Abstract: A cable barrier system is managed by a cable barrier management system including a management system controller having a management processor, a wireless data communications interface, and a plurality of turnbuckle subsystems configured to be joined to respective barrier cables to provide pretension. Each of the turnbuckle subsystems has a strain gauge mounting zone and is configured to enable communication of strain from a strain gauge circuit to the management processor. The management system controller includes a sensing circuit to receive the strain gauge output voltage from the strain gauge circuit and provide sensing circuit output to the management processor. The management system controller includes a cable barrier analysis module configured to determine excess strain events. The management processor generates strain event data, which is sent via the wireless data communications interface to a remote recipient computing device.

    Abstract: A tactile sensor including a cap having a top surface and an undersurface. The undersurface includes pins, each pin has a mark. A portion of the undersurface is attachable to a device. A camera positioned in view of the marks, captures images of the marks placed in motion by elastic deformation of the top surface of the cap. A processor receives the captured images and determines a set of relative positions of the marks in the captured images, by identifying measured image coordinates of locations in images of the captured images. Determine a net force tensor acting on the top surface using a stored machine vision algorithm, by matching the set of relative positions of the marks to a stored set of previously learned relative positions of the marks placed in motion. Control the device via a controller in response to the net force tensor determined in the processor.

    Abstract: There is provided a detection ring (600), the structure of which is shown in the perspective view of FIG. 13(a). The detection ring (600) is arranged so that the Z-axis is a central axis on the XY plane as shown in the side view (b), and a planar shape thereof is formed in a circular ring as shown in the bottom view (c). The detection ring (600) is structured so that four sets of detection portions (D1 to D4), each constituted with a blade spring which undergoes elastic deformation, are coupled with four sets of circular arc-shaped coupling portions (L1 to L4). A supporting substrate is arranged below the detection ring (600) and fixing points (P1, P2) arranged on the Y-axis are fixed to the supporting substrate. When force or moment to be detected is exerted on exertion points (Q1, Q2), the four sets of detection portions (D1 to D4) undergo elastic deformation. A displacement electrode is formed on a bottom of a displacement portion (63) at each of the detection portions (D1 to D4), and a fixed electrode is formed on a face facing the supporting substrate to form four sets of capacitive elements, thereby detecting force or moment exerted by operation on the basis of variation amount of capacitance values thereof.
