Abstract: A wearable device is disclosed. The wearable device comprises a glove, fingers, and one or more finger band cable guides connected to each of the fingers. A servo mount is coupled to the glove and a plurality of extension and flexion servo motors are coupled to the servo mount. A plurality of flexion cables and a plurality of extension cables are coupled to the plurality of extension and flexion servo motors and the fingers. An abduction and adduction servo motor is coupled to an abduction and adduction servo motor mount coupled to the glove. A controller actuates the plurality of extension and flexion servo motors and the abduction and adduction servo motor to move the finger portions. The wearable device further comprises a gyroscope to measure wrist movement and at least one vibration motor to provide haptic feedback to a wearer.

Abstract: The embodiments of the disclosure provide a method for inputting letters, a host, and a computer readable storage medium. The method includes: in response to determining that a first hand is presented as a first gesture, showing at least one letter set; in response to determining that the first hand has been changed from the first gesture to a second gesture corresponding to a first letter set among the at least one letter set, showing a subset of the first letter set, wherein the subset of the first letter set comprises at least one letter; in response to determining that a first letter among the at least one letter of the subset of the first letter set has been chosen, inputting the first letter.

Abstract: Embodiments of the presently described device, system and method support upper extremity (UE) therapy through tracking the human hand. The system can include a hand-wearable sensor mounting system with hand-wearable components and a movement interpretation circuit. The device can include a hand-wearable component comprising a hook, and a sensing transducer comprising a clip, wherein the clip is detachably securable to the hook. In embodiments, one or more sensing transducers are translationally and rotationally restricted when secured to the hand-wearable components.

Abstract: Systems and methods for providing high-capacitive RF MEMS switches are provided. In one embodiment, the invention relates to a micro-electro-mechanical switch assembly including a substrate, an electrode disposed on a portion of the substrate, a dielectric layer disposed on at least a portion of the electrode, a metal layer disposed on at least a portion of the dielectric layer, and a flexible membrane having first and second ends supported at spaced locations on the substrate base, where the flexible membrane is configured to move from a default position to an actuated position in response to a preselected switching voltage applied between the flexible membrane and the electrode, and where, in the actuated position, the flexible membrane is in electrical contact with the metal layer.

Abstract: A keyboard includes a housing having a number of passages formed by cylindrical members, a number of keys each having a shank slidably engaged in the passages of the housing, and an electromagnetic floating force generating device having a number of coils arranged to generate electromagnetic floating force and to float the keys relative to the housing. A number of magnets may be attached onto the keys and acted with the coils, to allow the keys to be floated by the electromagnetic floating force generated by the coils or the magnets. One or more fan devices may be disposed in the housing to circulate air through the keys.

Abstract: A housing assembly in which is placed a membrane keyboard is placed between the pressing layer and the base support. Pressing labels and key zones are respectively printed on a surface of the membrane keyboard and on the pressing layer at corresponding locations. An image layer with image features can be further placed between the pressing layer and the membrane keyboard. The housing assembly hence constructed can be fashionable by changing the upper cover and/or image layer, while the membrane keyboard can be further used on leveled working surfaces.

Abstract: A keyboard apparatus has keys for operation by a user. The keyboard includes a first plurality of keys being coupled to electrical generator apparatus for generating electricity from their operation. A second plurality of the keys is not coupled to electrical generator apparatus. The first plurality of keys exhibits a greater average statistical frequency of usage per key than does the second plurality.

Abstract: A system and method for entering text in a virtual environment by sensory gloves. The user enters a key that represents one or more letters by simulating a press of a keyboard in the gloves. The user calibrates the gloves by entering text, during which time the system establishes threshold values that represent simulated presses for each finger. After the initial calibration of the sensory gloves, the user enters text with simulated finger presses. The system distinguishes which movements are intended as simulated finger presses by examining the relative motions of fingers and maintaining dynamic thresholds. Errors are alleviated by providing feedback to the user, such as beeps and a visual display of the fingers and the current text. Because keys may represent more than one character, the system determines the intended text by probabilistic analysis and the Viterbi algorithm.
