  • Patent number: 10963724
    Abstract: An absolute position encoder includes a position location medium containing position identifier code words providing absolute position indications, and an optical source, an optical detector, an optics subsystem and a code word decoder. The optics subsystem focuses a source beam onto the position location medium and directs a return beam to the optical detector, detects a focus condition from the return beam, and automatically adjusts focus of the source beam to maintain a predetermined focus condition during operation. The code word decoder responds to the detector signal to detect a code word and generate a decoder output indicative of a corresponding code word value and corresponding detected position.

  • Patent number: 9743860
    Abstract: Various embodiments relate to apparatuses and methods of using light transmission thought living tissue, such as a finger, to detect the flexure of a joint. Light is introduced into the tissue at one point, passes through the tissue, and exits the tissue at a second point where a sensor receives the light as it exits the tissue. Transmission of light through living tissue such as a finger can be affected by movement of the finger. As the finger flexes and, for example, the joints of the finger change angle, the characteristics of the light exiting the tissue, such as the intensity of the light, can change. These changes in characteristics can be used as an indirect means of determining the flexure of the joint.

  • Patent number: 9519857
    Abstract: An apparatus includes a deformable structure in which a neural network comprising a plurality of deformation sensors, e.g. nanowire sensors, and distributed in-situ processing circuits. The circuits generate a signal characterizing features of the local deformation of the structure and/or a command signal corresponding to the detected deformation. The structure may be a wearable sleeve that conforms to deformations of a user's skin, part of an electronic device, such as a touch sensitive screen, or an object in itself. The apparatus can provide a user interface, wherein a command corresponding to a current shape of the structure is generated and acted upon by a integrated or remote device, or a device for monitoring a user's position or movement e.g. for replication by a robotic device. The apparatus may have machine learning capability to improve the matching of commands with determined shapes of the deformable structure.

  • Patent number: 9423311
    Abstract: A movement and expression sensor has a plurality of fiber Bragg gratings (FBG) disposed along the length of an optical fiber, and the optical fiber is placed in contact with a subject's skin surface. The sensors are interrogated for reflected wavelength, which is converted into a temperature or a strain. A series of such measurements can be made to determine the movement or position of the sensor location. A garment may be formed using the sensors and an elastomeric material, such that the sensors may be worn and removed, and the movements of the elastomer in the areas of sensors measured as a wavelength shift to characterize movement or estimate location. The elastomeric garment may be formed as a mask, or a sock, such as for use with a face, or foot.
