| 20080289883 | AUTOMATIC LIVESTOCK WEIGHING SYSTEM - A system for weighing a plurality of quadruped animals is for use in a pen confining the animals. The pen has at least first and second segregated spaces with a first one-way chute allowing animal passage from the second space to the first space. A weighing station is located within a passage having an entrance and an exit, and that allows animal passage from the first area to the second area. The weighing station includes a weighing platform within the passage over which an animal must pass when passing from the first to the second space. The weighing platform has inlet and exit scales that support the weighing platform adjacent to inlet and exit ends thereof, and provides inlet and exit weight signals. A controller receives the inlet and exit weight signals and uses them in an iterative process to determine the presence of a single animal on the weighing platform. Once that determination is made, the sum of the inlet and exit weight values is very likely to accurately provide the animal weight. The controller may also use the inlet and exit weight signals to control closing of an inlet gate to bar more than one animal at a time from the weighing platform. An animal sorting system can easily incorporate this weighing system to provide more accurate sorting. | 11-27-2008 |
| 20110127090 | Weigh-In-Motion (WIM) Sensor - In general, the disclosure is directed to techniques for sensing the weight of a load object passing over a measurement surface. In some examples, a weigh-in motion (WIM) sensor is provided that includes a first beam that exhibits a linear elastance function, and a second beam that exhibits a nonlinear elastance function. In additional examples, the WIM sensor may include a measurement circuit configured to generate information corresponding to a weight of the load object, a wireless transmission circuit configured to transmit the information to a receiving station, and an energy harvesting circuit configured to harvest an amount of energy from vehicle vibrations. The energy harvested may be sufficient to power the wireless transmission circuit. In further examples, a WIM system is provided that includes a sequence of sensors. Information from the sequence of sensors may be used to remove noise in the raw data due to vehicle vibration. | 06-02-2011 |
| 20110232974 | PORTABLE WEIGHING SYSTEM - A system for weighing a load is disclosed. The weighing system includes a pad having at least one transducer for weighing a load disposed on the pad. In some embodiments the pad has a plurality of foot members and the weighing system may include a plate that disposed underneath the pad for receiving the plurality of foot member and for aligning the foot members when the weighing system is installed. The weighing system may include a spacer disposed adjacent the pad and in some embodiments, a spacer anchor operatively secures the spacer to a support surface, such as a plate, a railway bed, or a roadway. In some embodiments the spacer anchor operatively secures both the spacer and the pad to a roadway. | 09-29-2011 |

| 20120160574 | VEHICLE PASSAGE TREAD SENSOR AND VEHICLE PASSAGE DETECTION APPARATUS - According to one embodiment, a vehicle passage tread sensor buried in a road in a direction substantially perpendicular to a traveling direction of a vehicle, includes a pipe including a cavity inside and formed of an elastic material, a fluid filling the cavity of the pipe, and a fluid pressure sensor configured to measure a pressure of the fluid. | 06-28-2012 |
| 20130008727 | WIND SHIELD FOR A TRUCK SCALE - A wind shield for shielding the sides of a truck scale so that the accuracy of the truck scale is less affected by wind forces. | 01-10-2013 |
| 20140014415 | WEIGHING DEVICE WITH A PRE-STRESSED CONCRETE DECK AND METHOD OF MAKING THE SAME - A weighing device comprises a plurality of weight sensors and at least one concrete deck. The weight sensors may be configured to determine a weight of an object. The concrete deck may be positioned on the weight sensors and may include a body, a first bulkhead, a second bulkhead, and a plurality of cables. The body may be formed from concrete. The first bulkhead may be positioned along a first end of the body. The second bulkhead may be positioned along an opposing second end of the body. The cables may be under tension and positioned within the body such that an outer surface of each cable is in direct contact with the concrete. | 01-16-2014 |
