  • Patent number: 7886618
    Abstract: A computerized prosthesis alignment system includes a transducer that can measure socket reactions in the anterior/posterior plane and the right/left planes, while canceling or reducing the transverse forces on the measurements of these socket reactions. In addition, the transducer is also capable of determining the axial load or weight experienced by the prosthesis. The computerized prosthesis alignment system is in communication with a host computer. The moment data from the transducer is interpreted by the user via a computer interface. The host computer includes memory for storing one or more applications. These applications receive data from the transducer, interpret the data with discrete algebraic or fuzzy logic algorithms, and display the output numerically and graphically. Applications may also interpret the data to provide analyses to the user for aligning the prosthesis.

  • Patent number: 7823464
    Abstract: A joystick apparatus employs a hermetically sealed load cell having strain gauges placed on flexible beams formed on the load cell. All of the strain gauges are on the same surface of the load cell and therefore wiring is performed on a single side of the load cell. The strain gauges are enclosed in hermetically sealed cavity. The sensing diaphragm consists of a concentric thick inner and outer section joined by thinner diametrically opposed beam elements. The thin beam elements are compliant members which can deflect. Each beam includes strain gauges or sensor elements and the load cell is coupled to a joystick which when moved causes the beams to deflect to cause the sensor elements to produce an electrical output proportional to the force and direction of the joystick. The sensor can yield an output proportional to any angle over the 360° movement of the joystick to provide outputs proportional to the X and Y positions of said joystick.

  • Patent number: 7823467
    Abstract: An electroactive polymer is used to produce a tactile sensor. The electroactive polymer (EAP) includes a sheet of an ion-exchange membrane having opposite surfaces on which are plated gold electrodes. The EAP is formed to have a dome-shape with a plurality of sensing electrodes circumferentially disposed around an outer surface of the dome. A flexible polymer underlying the EAP supports it and prevents a force applied to the tactile sensor from inverting the dome. The sensor electrodes produce separate output signals indicative of different vector components of an applied force acting on the tactile sensor, so that a direction of the force can be determined. Vias provided in the electrodes are electrically coupled to a flexible circuit that conveys the output signals externally from the sensing electrodes for use and further processing. A plurality of the tactile sensors can be formed as an array on an ion-exchange membrane.

A plurality of load sensors are symmetrically arranged at the base of the equipment. A Cartesian coordinate system is then imposed on the base of the equipment with the center of the base being the origin of the Cartesian coordinate system. The X-axis and the Y-axis of the Cartesian coordinate system are arranged to define a plane corresponding to the base of the equipment. Each load sensor is then designated with Cartesian coordinates and the reaction force at each load sensor is determined. An overall instability factor for the equipment is then determined from the Cartesian coordinates of each load sensor and the reaction force at that load sensor.

  • Patent number: 7792614
    Abstract: The load on an aircraft component is measured. In one embodiment, the system is a contactless, all-weather displacement measuring system including a processing unit and a plurality of pairs of controllable microwave emitters and microwave detectors. When the aircraft component is subjected to a load, relative movement of the emitter and detector is caused. The detector generates signals which convey information concerning the relative positions of the emitter and the detector of the pair, the signals being received and processed by a signal processor of the processing unit. The processing unit may, for example with the use of triangulation techniques, provide an output signal representative of the load sustained by the aircraft component. The system may be used to control braking in dependence on the output signal so as to maximise braking efficiency without overloading the landing gear leg.

Each cable 12 connects a first electrode 21 of a first detection element 11-(i, j) to a first electrode 21 of a second detection element 11-(i+1, j) via first resistances 32-1 to 32-4, and connects a second electrode 22 of the first detection element 11-(i, j) to a second electrode of the second detection element 11-(i+1, j) via second resistances 32-5 to 32-8. The cables 12 can be deformed. The two dimensional load distribution center position detection sensor 2 can cover a free-formed surface. This sensor is easy to manufacture because an elaborate sheet-shaped resistor is not needed.
