Abstract: A method of controlling a wearable tap detection system having a processor and a plurality of sensors for detecting contact by one or more fingers against a surface, including at least one mechanical sensor, includes detecting, as a tap event, a signal from the at least one mechanical sensor that exceeds a predetermined threshold. When the tap event is detected, the processor is switched from a first power mode to a second power mode, the second power mode using more power than the first power mode. Then, using the processor in the second power mode, processing of one or more signals from the plurality of sensors is performed to generate processed signal data. After the processed signal data is generated, the processor is switched from the second power mode to the first power mode.

Abstract: A one-handed, chorded data entry system enables an operator to tap a combination of fingers on any surface, thereby causing a character or command to be entered on an electronic device. The fingers can be arranged in any position and neither the fingers nor the fingertips of the user need be aimed at any particular target. Data indicating contact by finger combinations sharing a similar characteristic is mapped to characters sharing a similar characteristic. For example, data indicating contact by only one of five fingers during a data collection period is mapped to a respective one of the five vowels.

Abstract: Data receiving systems, methods and computer products are provided that include actuators in mechanical communication with fingers. Each of the actuators is arranged to apply a mechanical stimulus to a respective finger.

Abstract: A method for processing user input entered via a data entry system includes the steps of receiving a signal representative of a contact of one or more fingers singly or in combination against an arbitrary surface; detecting a predetermined number of contacts within a time window; and mapping the predetermined number of contacts to a secondary character from a set of secondary characters.

Abstract: A wearable data entry system includes a plurality of sensors corresponding to respective fingers of a user's hand, which are worn on the user's hand and generate respective signals representative of contact by one or more fingers against an arbitrary surface. A processor detects which fingers contacted the arbitrary surface by analyzing the signals during a data collection period and generates data indicating which fingers contacted the arbitrary surface during the data collection period, and a transmitter transmits information corresponding to the fingers that contacted the arbitrary surface to an external device, using a predetermined protocol. The wearable data entry system includes a memory that stores a mode value, and at least one of (i) the detecting by the processor and (ii) the predetermined protocol used by the transmitter, depends on the stored mode value.

Abstract: A device for simultaneously tapping threads and performing the usual operations of a punch press is described in which the tapping device is attached to the upper and lower plates of a punch press. As the punch plates are brought toward and away from each other, gear trains and helically grooved lead screws change the up and down motion into rotating motion. The gear trains also change the speed of the rotating motion which is used to drive a thread tapping tool through the metal being formed in the punch press. If there is too much force opposing the tapping operation, an electrical contact in the device is opened and the punch press stopped before the tap or tapping device can be damaged.
