    Abstract: A device disclosed herein includes a feedback measuring circuit to measure a signal flowing through a movable MEMS mirror. Processing circuitry determines a time at which the signal indicates that a capacitance of the movable MEMS mirror is substantially at a maximum capacitance. The processing circuitry also determines, over a window of time extending from the time at which the signal indicates that the capacitance of the movable MEMS mirror is substantially at the maximum to a given time, a total change in capacitance of the movable MEMS mirror compared to the maximum capacitance. The processor further determines the capacitance at the given time as a function of the total change in capacitance, and determines an opening angle of the movable MEMS mirror as a function of the capacitance at the given time.

    Abstract: A device described herein includes a movable MEMS mirror, with a driver configured to drive the movable MEMS mirror with a periodic signal such that the MEMS mirror oscillates at its resonance frequency. A feedback measuring circuit is configured to measure a signal flowing through the movable MEMS mirror. A processor is configured to sample the signal at first and second instants, generate an error signal as a function of a difference between the signal at the first instant in time and the signal at the second instant in time, and determine the opening angle of the movable MEMS mirror as a function of the error signal.

    Abstract: A touch controller is coupled to a touch screen and detects a first gesture at a first point on the touch screen. The first gesture includes physical contact of the touch screen by a user device at the first point. The touch controller detects a second gesture that is associated with movement of the user device from the first point to a second point on the touch screen. The second gesture includes detecting movement of the user device within a sensing range from the first point to the second point. The sensing range corresponds to an orthogonal distance from a surface of the touch screen. The touch controller detects a third gesture at the second touch point. The third gesture includes physical contact of the touch screen at the second touch point. Upon detecting the first, second and third gestures the touch controller performs a corresponding action.

    Abstract: An image sensor includes an array of pixels, with each pixel including a photodiode, and a first output circuit for deriving a linear output signal by applying a reset signal to the photodiode and reading a voltage on the photodiode after an integration time. A second output circuit derives a logarithmic output signal by reading a near instantaneous illumination-dependent voltage on the photodiode that is a logarithmic function of the illumination. In the logarithmic mode, the pixels are calibrated to remove fixed pattern noise. The pixels may be operated in linear and log modes sequentially, with the linear output being selected for low light signals and the log output being selected for high light signals.

    Abstract: Data is encoded in a solid state image sensor that includes a sensor pixel array by varying the color processing applied to at least some of the border pixels of the sensor pixel array. Data may be encoded in the color processing by varying the pattern of a color filter mosaic and by varying a pattern of a microlens array in accordance with a predetermined scheme. This scheme includes omission of color filter material and omission of the microlens array from selected pixels. The data, typically encoded in a binary format, is read by illuminating the sensor pixel array and by processing the output signals from the border pixels. The encoded data may include color process codes, mask revision codes and product codes.

    Abstract: Solid state image sensors, and methods of operation thereof, includes an array of photosensitive pixels arranged in rows and columns and in which pixel data signals are read out from the pixels via column circuits, which introduces column fixed pattern noise to the signals. The signals are selectively inverted at the inputs to the column circuits and the inversion is reversed following output from the column circuits. Each column circuit may include an analog-to-digital converter and a digital inverter for inverting digital output therefrom. The selective inversion may be applied to alternate rows or groups of rows of the pixel data, and may be applied differently to different frames of the pixel data. These techniques result in column fixed pattern noise being modulated in a manner which makes the noise less apparent to the eye, and which facilitates subsequent cancellation of the noise.

    Abstract: A method of mounting an electronic component having at least one contact extending across a part of its undersurface may include providing a support smaller in area than the undersurface of the component and having a contact pad for connection to the contact. The contact pad may have a first portion extending across an upper surface of the support adjacent one edge and a second portion extending from the edge across a side surface of the support. The method may also include positioning the electronic component and the support with the undersurface of the component adjacent the upper surface of the support. This is done so that the first portion of the contact pad is aligned with and spaced apart from a first portion of the contact, and the second portion of the contact pad is aligned with and disposed inwardly of a second portion of the contact.

    Abstract: A method of operating a display includes performing a non-synchronized touch scan pattern on a display with a controller coupled to the display. The non-synchronized touch scan pattern schedules touch scans independent of a refresh rate of the display. Upon the controller detecting a first synchronization pulse from a display controller coupled to the controller and the display, a first pulse-checking timer is started. Upon detecting a second synchronization pulse from the display controller and before the first pulse-checking timer expires, a first display refresh rate for the display is obtained from an interval between the first synchronization pulse and the second synchronization pulse. A synchronized touch scan pattern is performed with the controller, and is scheduled to avoid touch scans coinciding with refreshes of the display performed at the first display refresh rate.
