A sensing system implements one or more MEMS microphones in order to measure mechanical waves. The sensing system can be part of a larger system used to determine motion and position of a user's hand or other body part. The MEMS microphones can be part of a plurality of MEMS microphones. There may additionally be MEMS microphones that transmit mechanical waves at certain frequencies that can be measured by the MEMS microphones and subsequently distinguished from other mechanical waves and used to determine additional information regarding movement and position.

MEMS sensing system

Disclosed is a controller for sensing deformation. Transmit antennas are located on a first structure and transmit signals. Receive antennas are located on a second structure and receive signals. Received signals are processed to determine an amount of deformation. The amount of deformation that occurs may then be correlated to the position of a hand or the location of another body part.

Apparatus and method for sensing deformation

A multimodal sensing system comprises a plurality of sensors placed proximate to a body part. The sensing system receives, using a plurality of sensors, a plurality of signals related to at least one of a movement and a pose of the body part. The sensing system then extrapolates information regarding the type of movement or pose and at least one characteristic of the type a movement or pose.

Wearable multimodal-sensing device

Methods and devices for providing fast multi-touch sensors are disclosed. In an embodiment, a method is provided for design and manufacture of touch sensors for touch-sensitive devices. At least one behavioral quality is identified for the touch-sensitive devices. At least one parameter is selected, the parameter being associated with the composition or geometry of a stack of row conductors and column conductors on each of the touch sensors associated with the devices, the selection being based on the identified at least one behavioral quality. Multi-touch sensors are then manufactured by arranging a plurality of row conductors and a plurality of column conductors in a stack such that the stack or a component thereof has a geometry or composition that meets the at least one parameter. An orthogonal signal transmitter is provided for simultaneously transmitting each of a plurality of orthogonal row signals on a respective one of at least some of the plurality of row conductors. A detector is provided for detecting an amount of each of the plurality of orthogonal row signals present on each of the plurality of column conductors. Specific multi-touch sensors are also disclosed for hover applications, large screen applications, and others.

Capacitive sensor patterns

Methods of mitigating noise in a FMT sensing system. Noise and touch events are identified in the system. Noise and touch events can be identified and determined to be aperiodic or periodic. After establishing the type of noise in the system. The frame rate or processing of frames can be adjusted in order to remove the noise during the processing of touch events.

Noise mitigation for a frequency domain sensor

A sensor system comprises a plurality of receiving antennas. Another antenna functions as an isolating antenna that assists in preventing a signal received at some of the receiving antennas from being interfered with by the other receiving antennas. The isolating antenna may be operably connected to a ground or the source of signal that is also infused into a user.

Matrix sensor with receive isolation

An array of antennas form a sensor device. Some of the array of antennas function as receivers and some of the array of antennas function as transmitters. Each of the transmitters may transmit a unique frequency orthogonal signal that may be received at the receivers. Measurements of the received signal are then used to determine activity within field lines.

Matrix sensors

A touch sensitive keyboard is disclosed. In one embodiment, a touch sensitive keyboard is provided that has a touchpad area separate from the keyboard keys. The keyboard is configured to disabled touchpad sensitivity when certain touch signals are received. In another embodiment, a touch sensitive keyboard is used as a controller. In a controller mode, keys on a touch sensitive keyboard are adapted to output a signal strength corresponding to a distance between the key and a finger operating as a control. In an embodiment, a touch sensitive keyboard includes a processor adapted to output a keystroke in response to one of the plurality of touch sensitive keys being pressed, and to output one or more touch points determined by interpolating signal strength for each of the plurality of touch sensitive keys on the keyboard.

Touch sensitive keyboard

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.

Flexible deformation sensor

A sensor system comprises a plurality of receiving antennas. Another plurality of antennas functions as transmitting antennas. The antennas may be placed on a deformable substrate. The deformable substrate may be part of a band that is worn proximate to a hand.

An array of antennas form a sensor device. Some of the array of antennas function as receivers and some of the array of antennas function as transmitters. Each of the transmitters may transmit a unique frequency orthogonal signal that may be received at the receivers. Measurements of the received signal are then used to determine a hand motion.

Matrix sensors for use with a controller

Disclosed are keyboards and keyboard switches sensitive to touch, including, hover and pressure. The keyboard switches have transmit and receive antennae that are spaced apart such that no portion of the transmit antenna touches any portion of the receive antenna. The keyboard switches are arranged in logical rows and logical columns such that each of the keyboard switches is associated with one row and one column. Signal emitters are conductively coupled to the transmit antennae for each of the keyboard switches associated with each of the rows, and each of the signal emitters are adapted to cause each of the transmit antennae to transmit one or more source signals. Receivers are coupled to the receive antennae for each of the keyboard switches associated with each of the columns, and each of the receivers are adapted to capture a frame of signals present on the coupled receive antennae. A signal processor adapted to determine a measurement from each frame, corresponding to an amount of the source signals present on the receive antennae during a time the corresponding frame was received. The signal processor further adapted to determine a keyboard switch touch state from a range of touch states based at least in part on the corresponding measurement.
