摘要： Two or more objects, or an object and an environment are each fitted with two or more range measurement devices. Each of the range measurement devices is provided with a transceiver capable of outputting a unique code and information that can be used in range measurement, and receiving from other range measurement devices unique codes and information that can be used in range measurement. Range measurements from range measurement devices on the object or located in the environment are used to derive the relative position of the range measurement devices, from which a relative position of the objects, or of the object and an environment can be derived.

摘要： A low-latency touch sensor is disclosed for use in connection with a touch surface having first and second conductors sensitive to changes in coupling therebetween as a result of touch (and/or near-touch). A signal generator generates unique orthogonal signals, a transmitter transmits the orthogonal signals on each of the first conductors. Receivers connected to the second conductors receive signals during a measurement period. The signals measured during the measurement period are processed to determine, for each measurement period, and for each of the second conductors, a signal strength corresponding to each of the unique orthogonal signals. The signal strengths can be used as a basis to determine touch events.

摘要： Differential transmission is provided in a capacitive sensor for reducing cross-talk between rows and columns. A capacitive touch sensitive device as disclosed herein includes row conductors and column conductors, a first row signal generator for transmitting a first row signal on a first row conductor, a second row signal generator for transmitting a second row signal on a second row conductor, and a touch processor for identifying a touch event on the touch interface by processing signals present on at least one of the column conductors. The first and second row signals together form a differential row group of signals that cancel each other out or at least substantially mitigate each other so as to reduce cross-talk interference in the sensor.

摘要： Methods are disclosed for dynamic assignment of possible channels in a touch sensitive device having rows and columns. In an embodiment, a method determines a first signal space in which to generate signals for use in the touch sensor. Signals are then generated in the first signal space on separate ones of the rows and a column signal is sensed on a column. The first signal space is replaced with a second signal space, and a second plurality of signals is generated for use in the touch sensor in the second frequency space. The second plurality of signals is sensed to identify a touch event in the touch sensitive device.

摘要： System and processes for transmitting orthogonal frequencies on a touch sensor are provided. In one example process, the rows of the sensor panel can have signals transmitted thereon having orthogonal frequencies. The orthogonal frequencies can be separated by a frequency spacing (Δf) that is at least the reciprocal of a measurement period τ (e.g., an integration time) of the touch sensor. Touch events cause and correspond to signals on the columns, which can be received by a receive system including appropriate amplifiers. The orthogonal frequencies can be detected by the receiver with a Fourier Transform or filter bank. Separate digitization and signal processing can be implemented for every column. The receiver can measure the quantity of each of the orthogonal transmitted signals present on each column, identifying the rows in touch with each column and may also provide additional (e.g., qualitative) information concerning the touch.

摘要： A sensor for sensing contact with an outside object is disclosed. A sensor stackup has top surface, having an outer skin adapted for contact with the outside object. The stackup also including, a deformable layer below top surface in the stackup, the deformable layer including patches made from conductive or high dielectric material. The stackup further including a capacitive sensor layer below the deformable layer, the capacitive sensor layer comprising conductors that are insulated from the patches. Each of the patches is displaceable with respect to the capacitive sensor layer in response contact with the outside object. The stackup also includes a backing layer below the capacitive sensor layer in the stackup. The sensor further includes capacitive sensor circuitry operatively connected to the capacitive sensor layer, the capacitive sensor circuitry configured to detect changes in capacitive coupling between the conductors of the capacitive sensor layer resulting from displacement of the patches with respect to the capacitive sensor layer.

摘要： A frequency division modulated touch detector having row and column conductors arranged such that the path of the row conductors cross the paths of the column conductors, and signal emitters associated with each row, the emitters being adapted to transmit a signal having a specific frequency and initial phase on each row conductor, and a receiver associated with each column to receive signals present on the column conductor. A signal processor is adapted to determine an in-phase and a quadrature component for each of the transmitted signal found in the received signals, and to project a vector representing the transmitted frequencies at their initial phase onto the respective in-phase and quadrature component to determine a measurement for each transmitted signal on each column, and create a heat map reflecting those measurements, the heat map thus containing data reflective of touch.

摘要： A method and system for determining distance from a conductor. A signal is infused into object or into a body part. Calibration occurs by moving the object to at least two known distances and measuring the signal. Using the measured signals, a signal-to-distance map can be created and used to determine the distances of additional objects or body parts.

摘要： In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.
