| 073862610 | By measuring a counterbalancing or restoring force | 6 |
| 20110107852 | TEMPERATURE INSENSITIVE DEVICES AND METHODS FOR MAKING SAME - An apparatus and method for estimating a parameter of interest using a force responsive element comprising, at least in part, a balanced material. The balanced material is temperature insensitive over a specified range of temperatures such that the force responsive element may estimate the parameter of interest by responding to a desired force with relatively little interference due to temperature changes within the specified range of temperatures. | 05-12-2011 |
| 20110283814 | APPARATUS FOR PERFORMING A LOADING TEST IN AN ELEVATOR SYSTEM AND METHOD FOR PERFORMING SUCH A LOADING TEST - An apparatus and method for performing a load test in an elevator installation having an elevator car and a counterweight, which are connected to one another by a supporting device, and a drive brake for halting the elevator car during a downwards journey. The apparatus has a connecting element for fastening to the counterweight, an element with spring properties and a tensioning device for installation in the elevator installation. One point of the tensioning means is fixed to a stationary point of the elevator installation via the element with spring properties. Another point of the tensioning means is connected to the counterweight via the connecting element, wherein the tensioning device includes an actuating device with which to tension the element with spring properties in order to thereby exert a downwardly directed tensile stress on the counterweight. | 11-24-2011 |
| 20120234106 | SEALED, SLIM-LINE CONSTANT FORCE, GENERATION UNIT - The present disclosure relates to a sealed constant force generation system utilizing a spring system comprising a spring system housing unit, spacers, interchangeable spring load rod and conical spring washers, a puller assembly comprising a puller, pivot assembly, seal system and o-ring, a lever arm system, an adjustment system, a load stopper and fulcrum housing unit. A method for applying the sealed constant force generation system on objects or loads experiencing a specific displacement is also disclosed. | 09-20-2012 |
| 20140102218 | FORCE TRANSDUCER FORMING A LOAD CELL - A force transducer, in particular a weighing cell, includes a spring body, which deforms under the action of a force or load to be measured, and a sensor that includes two separate sensor parts mounted at different locations of the spring body and that generates a sensor signal which is dependent on the relative position of the sensor parts with respect to each other. In order to improve the adaptation of the sensor to the spring body, one of the sensor parts is attached to the spring body with interposition of an electromechanical actuator and a control device is present, which controls the actuator dependent on the sensor signal in the direction of a reduction in the positional difference of the sensor parts. | 04-17-2014 |
| 20150033876 | DETERMINING A POSITION BY MEASURING FORCES - A device and a method determines the position of an object which can be moved in a linear manner. The device includes a contact unit coupled to the object such that the contact unit provides a force signal that is dependent on the position of the object; a force detecting unit for detecting the force signal provided by the contact unit; and an evaluating unit for evaluating the force signal detected by the force detecting unit. The position of the object is ascertained using an evaluation function during the evaluation process, the evaluation function describing a dependence of the force signal on the position of the object. | 02-05-2015 |
| 20150107375 | BALANCE OPPOSITION COMPARATOR - Tennis players need multiple playing racquets available for their use, and the mass proportions of each one, needs to match all the others exactly, otherwise players will likely experience degradation in their swing mechanics when unmatched racquet's were used. | 04-23-2015 |
