Patent number: 7050938Abstract: A package handling system for use with a plurality of packages having package identification thereon. The system of one embodiment comprises processing stations where packages having heterogeneous contents are processed. One or more identifiers are positioned at the processing stations to detect the package identifications associated with the packages. A controller is coupled to the identifier to receive identification information about a package and detected by the identifier. The controller is coupled to the data input device to receive first package data related to an actual condition of the package. The controller has second package data related to acceptable package conditions. The controller uses the first and second package data to determine if the package is in a kickout condition.Type: GrantFiled: October 6, 2004Date of Patent: May 23, 2006Assignee: Amazon Technologies, Inc.Inventors: Alexander C. Prater, Suzanne C. Reynolds, Mackenzie Smith

Patent number: 7024295Abstract: A method and system for determining weight and/or position of a vehicle seat occupant to be used for controlling the reaction of a safety restraint system. A plurality of spaced weight sensors are disposed between a seating surface and seat mounting surface to provide output signals indicative of an applied weight on each sensor. The sensors are spaced such that the sensors measure the weight applied to a seat back and the seating surface. A controller calculates the weight and/or position of the seat occupant in response to the output signals of the sensors. The controller sends the weight and position of the seat occupant to the safety restraint system to be used to tailor or suppress the reaction of the safety restraint system.Type: GrantFiled: April 29, 2005Date of Patent: April 4, 2006Assignee: Siemens VDO Automotive CorporationInventors: Ralf Oestreicher, Michelle Homann, Harold Lichtinger, Scott Morell, Dan Reich

Patent number: 6983883Abstract: In a freight shipment system and method, the lift trucks used by the freight carrier for handling and loading freight shipments are equipped with a weighing device capable of weighing each piece of freight handled by the lift truck. The lift truck is also equipped with a scanner for scanning coded identifying information associated with each piece of freight. As each piece of freight is handled by the lift truck, the coded identifying information for that piece of freight is captured along with the weight of the load. This information is transmitted to a computer system where it can be used for real-time invoicing. The system can also use the captured information to perform additional automated functions, such as tracking of shipments, freight loss control, and assisting in avoiding overloaded trucks.Type: GrantFiled: April 28, 2003Date of Patent: January 10, 2006Assignee: Speed Trac Technologies, Inc.Inventor: David J. Ridling

Patent number: 6915233Abstract: An apparatus and method capable of measuring a weight load of an inflamed leg of a lab animal or a human being objectively and precisely while the lab animal or the human being is walking freely in a non-binding state. A pathway sized depending on a size and a stride of the lab animal or the human being is provided in a weight load measuring apparatus, and a weight sensor is attached to a bottom of the pathway. Thus, artificial operations to be applied to the lab animal or human being walking the pathway can be minimized such that the weight load exerted in the inflamed leg can be measured objectively and precisely with time periods.Type: GrantFiled: August 21, 2003Date of Patent: July 5, 2005Inventors: Hee Chul Han, Seung Kil Hong, Heung Sik Na, Young Wook Yoon, Yang In Kim, Sun Seek Min, Jeong Seok Han

Patent number: 6884946Abstract: A scale for weighing an item and determining a price for the item includes a weighing station for receiving the item, the weighing station producing at least one weight indicative signal. A scale controller receives the weight indicative signal and determines the price for the item based upon the weight indicative signal. A remote interface link includes associated communication software. A web server associated with the controller serves user interface web page data to the remote interface link for transfer to a remotely located device. Advanced functions such as a monitoring function and service functions may be enabled by remote connection to the scale via the remote interface link.Type: GrantFiled: March 5, 2002Date of Patent: April 26, 2005Assignee: Premark FEG L.L.C.Inventors: David Scott Miller, Joe Howard Crew, Clare Cecelia Dickey, Lawrence A.

Patent number: 6868364Abstract: A method for determining the weight of a load upon a load support of a hydraulic lifting device, in which the pressure of hydraulic fluid within a lifting cylinder is measured and a stored reference curve representing the relationship between the weight of the load and the hydraulic fluid pressure is determined by multiple measurements of the pressure resulting from loads of known weight and the reference curve. According to the method, the load support is lifted and lowered during a short period upon operator request or automatically to sense the load before and during load lifting and lowering operations and a plurality of pressure measuring values are obtained. A pair of average values of the pressure measuring values for respectively lifting and lowering is generated, as well as a third average value of the pair of average values. The third average value is then applied to the reference curve for determining the weight of the load.Type: GrantFiled: December 8, 2003Date of Patent: March 15, 2005Assignee: Jungheinrich AktiengesellschaftInventors: Uwe Allerding, Sebastian Lehnart

Patent number: 6859753Abstract: An apparatus and method for supporting a load-bearing platform (e.g., a seat) and measuring the weight of a load (e.g., an occupant) on the platform. The apparatus can include a base or support, a lever coupled to the support, and a sensor. The lever can be pivotally coupled to the support to allow pivotal movement of the lever with respect to the support in response to weight applied to the platform. The sensor can detect the force transmitted by the lever to determine the weight of the load on the platform. Furthermore, the lever can isolate the vertical load on the platform due to the weight of the load from other extraneous, non-vertical forces on the platform.Type: GrantFiled: August 26, 2003Date of Patent: February 22, 2005Assignee: Robert Bosch CorporationInventors: Rajeev Thakur, Chad Vanfleet, Aleksandr Golshteyn
