A system for tracking and monitoring a game ball, wirelessly gathering data from the ball, game elements, players, officials, to improve timeliness and accuracy of game, includes a wireless tag disposed within ball to provide an identification, wirelessly communicable with a receiver to indicate a position in X, Y, Z coordinates, such that ball edge locations are identified; wireless communication system tag reading devices arranged in an array, each configured to sense and read each wireless communication system tag; a pressure sensor disposed upon player and configured to send signal of sudden pressure change; a computer control center connected to the wireless communication system tag and tag reading devices, configured for receiving, computing, processing a plurality of game data and communicating a decisive signal for exact position for placement of ball; and a personal computing device worn by game official for communications and configured to send, receive data during game.
摘要:
Treatment devices for fluid such as water are described. Principally (although not necessarily exclusively) designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A return tube of the device may be designed to create vortex action, using a pressure differential to evacuate treated water from the device back into the conduit.
摘要:
Treating, sensing, diverting, measuring, and collecting devices for fluid such as water are described. When designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A return tube of the device may be designed to create vortex action, using a pressure differential to evacuate treated water from the device back into the conduit. When designed for use as feeders for supplying acid or other material to flowing water, the devices may include one or more channels communicating between the material and the flowing water. When designed for use as flow sensors or otherwise, the devices may include objects acted upon by flowing water to indicate that water indeed is flowing. Yet other sensors may be utilized to determine characteristics of water passing through the conduits.
摘要:
A surveillance camera mount assembly for attaching a surveillance camera to a support comprising a surveillance camera housing having a top surface with a plurality of threaded members, a plurality of nuts having threads that mate with the threaded members, and a mount having a mechanical connector for attaching the mount to a support and having a plurality of elongated apertures that align with the plurality of threaded members. The elongated apertures having first and second aperture portions with the first aperture portion being sized so that one of the nuts can pass through it and a second aperture portion being sized so that one of the nuts cannot pass through it.

Injection molded bumpers for off-road recreational and utility vehicles such as ATV's, snowmobiles and the like. In one embodiment, the invention provides an injection molded bumper comprising a fiber-filled plastic resin body. Optionally, the fiber-filled plastic resin may have fibers of a length of at least about ¼ inch. The body has an overall thickness substantially less than its width and length, and includes a generally vertically oriented front surface having upper and lower peripheral edges. At least a portion of the upper peripheral edge and at least a portion of the lower peripheral edge each has a flange extending generally horizontally away from the front surface. The flanges have thicknesses substantially less than the lengths they extend from the front surface and thereby define generally horizontally extending reinforcing ribs. Additional reinforcing ribs may also be provided intermediate the flanges.
摘要:
A risk of fall detection system comprising: a wearable monitoring group configured to acquire posture data and comprising: a first sensor configured to be attached to a lower part of a user's torso and to detect the position of said lower part, a second sensor configured to be attached to an upper part of the user's torso and to detect the position of said upper part, a third sensor configured to be attached to at least one user's lower limb and to detect the position of said user's lower limb, a processing module in signal communication with the wearable monitoring group and configured to process the acquired posture data and to compute a risk of fall indicator parameter from the relative position of the lower part of user's torso, upper part of user's torso, and user's lower limb detected by the first, second and third sensor, respectively.
