A slip ring for use in a slip ring brush type rotation sensor device, includes a metal ring having an approximately cylindrical shape, and a resin ring that supports the metal ring. Slits extending in an axial direction are formed in respective side surfaces on outer peripheries of the metal and resin rings. The metal ring includes a common part formed on a side surface at one end along the axial direction of the approximately cylindrical shape and segmented by the slits into segments to form common regions, so that adjacent common regions are electrically connectable to each other, and a detection part formed on a side surface at the other end and segmented by the slits into segments to form conducting regions and isolated regions that are alternately provided with the slit interposed between adjacent conducting and isolated regions.

A controller for sensing deformation including a sensor structure having a deformable conductor and another conductor (which may also be deformable). The deformable conductor may be made out of a flexible non-fluid material (e.g., rubber) or a conductive fluid. The deformable conductor may be deformed by the deformation of the sensor structure or by other forces. The sensor comprises circuitry to drive and sense signals on interacting pairs of conductors (the deformable conductor or the other conductor can act as the drive side, or as the sense side). Sense signals are processed to analyze deformation of the deformable conductor, and deformation of the sensor structure. Where the sensor is deployed proximate to human skin, deformation and changes in deformation may be used to correlate or infer a body position, movement or pose.

An apparatus for measuring a profile of a tubular string and the components thereof as the tubular string is made up and run into a borehole. The apparatus includes a rotating assembly disposed within a housing, the rotating assembly including a plurality of upper legs, and plurality of lower legs and a plurality of rolling elements, each upper leg having a proximal end and a distal end coupled to an upper ring, each lower leg having a proximal end coupled to a lower ring and a distal end, and each rolling element rotatably coupled to the proximal end of an upper leg and a distal end of a lower leg. The apparatus further includes a sensor for detecting a position of the rolling elements as they engage an exterior surface of a tubular string being made up and run into a borehole from a rig. The apparatus receives the tubular string through aligned central passages in the upper ring, lower ring and the rotating assembly.

A rotation control apparatus includes a relative position sensor that contactlessly detects the mechanical displacement amount of a shaft to be actuated in a direction of rotation, absolute position sensors that are provided at mutually different positions within a rotatable range of the shaft to be actuated and each output a detection signal when the shaft to be actuated has reached its corresponding position, and a position calculating unit that calculates an absolute position of the shaft to be actuated in the direction of rotation on the basis of an integrated value of the mechanical displacement amount since the detection signal is output and a reference value indicating a position corresponding to the absolute position sensor that has output the detection signal. At least one of the absolute position sensors is provided to correspond to a third position excluding a first position and a second position within the rotatable range.

A rotary sensor assembly comprises an indicator member adapted to rotate and having first and second axial positions, input means adapted to be actuated by movement of the indicator member, and a processor adapted to receive input from the input means. The indicator member comprises a plurality of actuator structures, and the input means comprises one or more switches adapted to be actuated by an actuator structure. Zero or more switches is/are actuated when the indicator member is moved from the first to the second axial position, this corresponding to a first switch pattern, and zero or more switches is/are actuated when the indicator member is moved from the second to the second axial position, this corresponding to a second switch pattern. Based on input from one or more switches corresponding to the first and second switch patterns, the processor is adapted to determine rotational movement of the indicator member.

A drug delivery device, comprises a housing having a longitudinal axis; an axially moveable component that is moveable along the longitudinal axis between a dose dialing position and a dose delivery position when a user operates the device to deliver a dose of drug; an encoder sleeve; an encoder pattern provided on the encoder sleeve, the encoder pattern comprising relatively conductive portions and relatively non-conductive portions that together comprise coded information; a contact-supporting component; and plural electrical contacts provided on the contact-supporting component. The plural electrical contacts contact the encoder pattern when the dose delivery button is in the dose dialing position and wherein the device is configured to move the contact-supporting component relative to the encoder sleeve as the axially moveable component moves from the dose dialing position to the dose delivery position such as to move the electrical contacts into positions where they do not contact the encoder pattern.
