A multipurpose tool for gripping an object and determining an orientation of a surface comprises a first arm with a jaw at one end and a grip at an opposite end and a second arm pivotally connected to the first arm about a pivot point. The second arm also has a jaw at one end and a grip at the opposite end. The grips are moveable between an open position for opening the jaws and a closed position for closing the jaws. At least one level vial is mounted on at least one of said arms such that the arm may be placed into engagement with the surface for determining the orientation of the surface.

The selection and output of a signal, such as an alphanumeric character, is provided depending upon the orientation of a device, such as a mobile telephone. In particular, a neutral position of a device is determined in relation to at least a first axis, the device including at least a first control associated with a first plurality of output signals, and an angular displacement of the device is measured about at least the first axis. A selection of the first control is also received, and one of the first plurality of output signals is output based at least upon the selection and the angular displacement.

Systems are arranged to provide a user information which relates to objects of interest. A user may point a hand held device toward an object to address it. The device determines which objects are being addressed by making position and attitude measurements and further a reference and search of a database containing preprogrammed information relating to objects. Information relating to objects determined as objects presently being addressed is thereafter presented at a user interface. Devices of these systems include a point reference, a direction reference, a position determining support, attitude determining support, a computer processor and database, and a user interface. Methods of systems include the steps of addressing an object, determining position and attitude, searching a database, and presenting information to a user.

A system is provided for capturing motion of a moving object via a plurality of motion sensor modules placed on various body segments. The sensor modules capture both 3D position and 3D orientation data relating to their respective body segments, thereby gathering motion data having six degrees of freedom with respect to a coordinate system not fixed to the body. Each body sensor collects 3D inertial sensor data and, optionally, magnetic field data. In embodiments, either DSP circuitry within the sensor modules or an external computing device, processes the sensor data to arrive at orientation and position estimates by using an estimation algorithm, such as a Kalman filter or a particle filter. The processing includes biomechanical model constraints that allow flexibility in the joints and provide characteristics for various joint types. To improve estimation accuracy, the system may be integrated with various types of aiding sensors.

A multi-panel electronic device and method are disclosed. In a particular embodiment, a method includes receiving first acceleration data from a first sensor coupled to a first portion of an electronic device. The method further includes receiving second acceleration data from a second sensor coupled to a second portion of the electronic device, where a position of the first portion is movable with respect to a position of the second portion. The method further includes determining a configuration of the electronic device at least partially based on the first acceleration data and the second acceleration data.

A method and apparatus are provided to acquire direct thermal measurements, for example, from a LiDAR collecting vehicle or air vessel, of an overhead electrical conductor substantially simultaneous with collection of 3-dimensional location data of the conductor, and utilize temperature information derived from the direct thermal measurements in line modeling, line rating, thermal line analysis, clearance analysis, and / or vegetation management.

A system, apparatus and method for three-dimensional scanning and digitization of the surface geometry of objects are claimed. The system includes a hand-held apparatus that is auto-referenced. The system is auto-referenced since it does not need any positioning device to provide the 6 degree of freedom transformations that are necessary to integrate 3D measurements in a global coordinate system while the apparatus is manipulated to scan the surface. The system continuously calculates its own position and orientation from observation while scanning the surface geometry of an object. To do so, the system exploits a triangulation principle and integrates an apparatus that captures both surface points originating from the reflection of a projected laser pattern on an object's surface and 2D positioning features originating from the observation of target positioning features.

The present invention provides an electromagnetic tracking system that includes a field generator and a field sensor arranged to generate and detect, respectively, an electromagnetic field. Both the transmitter and receiver coils are connected to signal conditioning and processing circuitry to provide outputs indicative of the coil signals. A processor operates on the signals to determine the coordinates of the sensing assembly relative to the generator assembly. The signal processor produces ratiometric outputs, and applies a mutual inductance model to solve for position / orientation coordinates. In some embodiments, a disturber in the form of a conductive ring or a sheath is disposed about an interfering piece of equipment to moderate and standardize disturbances due to eddy currents.

A portable coordinate measurement machine for measuring the position of an object in a selected volume includes a positionable articulated arm having a plurality of jointed arm segments. The arm includes a measurement probe having an integrated line laser scanner mounted thereon. The laser may be a thermally stabilized laser.

A highly miniaturized electronic data acquisition system includes MEMS sensors that can be embedded onto moving device without affecting the static / dynamic motion characteristics of the device. The basic inertial magnetic motion capture (IMMCAP) module consists of a 3D printed circuit board having MEMS sensors configured to provide a tri-axial accelerometer; a tri-axial gyroscope, and a tri-axial magnetometer all in communication with analog to digital converters to convert the analog motion data to digital data for determining classic inertial measurement and change in spatial orientation (rho, theta, phi) and linear translation (x, y, z) relative to a fixed external coordinate system as well as the initial spatial orientation relative to the know relationship of the earth magnetic and gravitational fields. The data stream from the IMMCAP modules will allow the reconstruction of the time series of the 6 degrees of freedom for each rigid axis associated with each independent IMMCAP module.

A method for tracking an object includes producing energy fields at a plurality of different frequencies in a vicinity of the object, and receiving signals that are generated at a location of the object at the different frequencies in response to the energy fields. Multiple computations are made of spatial coordinates of the object based on the signals received at the different frequencies. Convergence of the computations is tested in order to ascertain whether the energy fields have been perturbed by an article in the vicinity of the object.
