    摘要: A PNP apparatus may include a robotic arm, and a PNP tool head carried by the robotic arm. The PNP tool head may include a body configured to apply bonding pressure to a first area of an electronic device, and a pick-up tip movable between an extended position and a retracted position relative to the body as the pick-up tip rests against a second area of the electronic device. The pick-up tip may define a vacuum passageway therethrough to couple a vacuum source to the second area of the electronic device.

    摘要: A start/stop condition detection circuit is coupled to receive the SDA and SCL signals from an IIC Bus. The circuit generates a first signal in response to an edge of the SDA signal and generates an inversion of the first signal as a second signal in response to an opposite edge of the SCL signal. The first and second signals are logically combined to generate an output signal. The particular directions of the edges of the SDA and SCL signals that the circuit is response to determines whether the output signal is indicative of a start condition detection or a stop condition detection.

    摘要: The back EMF (BEMF) of a motor is sensed and compared to a target back EMF (BEMF) to generate an error control signal. The circuit supply voltage is also sensed. A PWM motor control signal is generated in response to a comparison of the error control signal to a ramp signal having a variable slope. The variable slope is selected in response to the sensed circuit supply voltage. The motor is then driven in response to the PWM control signal. The sign of the error control signal is used to selectively short one of motor terminals to a reference voltage supply node while the other motor terminal is driven in response to the PWM control signal.

    摘要: A system for determining an aspect ratio of image content based on an analysis of the content. In an embodiment, an analyzer is configured to receive a data input corresponding to an image in a stream of images that constitute a video sequence of images. The analyzer is further configured to determine a mathematical representation of the image content based on a power spectrum analysis of vertical components of the image in comparison to a power spectrum analysis of horizontal components of the image. Based on this comparison of the vertical frequency components to the horizontal frequency components, a determination about the original aspect ratio of the image may be determined. This determination may be used by a video processor to correctly apply aspect ratio conversion for final image output.

    摘要: Apparatus and methods to measure capacitance changes for a touch-sensitive capacitive matrix are described. Charge-removal circuits and measurement techniques may be employed to cancel deleterious effects of parasitic capacitances in the touch-sensitive capacitive matrix. Capacitively switching a supply during timed charge removal may be used to cancel unwanted effects due to clock jitter. The apparatus and methods can improve signal-to-noise characteristics, sensitivity, and/or dynamic range for capacitive measurements relating to touch-sensitive capacitive devices.

    摘要: Applicant has recognized and appreciated the desirability of powering an actuator using power drawn from one or both of an energy storage device and a spindle motor. In some embodiments, following a loss of external power to a hard disk drive, the hard disk drive (or one or more components thereof) determines whether to provide the actuator with power drawn from the spindle motor or to provide the actuator with power drawn from the spindle motor and from the energy storage device. In some embodiments, the hard disk drive (or the component(s) thereof) may additionally or alternatively determine whether to charge the energy storage device using power drawn from the spindle motor. In some embodiments, the drive may make the determinations based on an amount of power that the actuator is to consume at a time and an amount of power that the spindle motor can provide at the time.

    摘要: Embodiments provide a method and system of text independent speaker recognition with a complexity comparable to a text dependent version. The scheme exploits the fact that speech is a quasi-stationary signal and simplifies the recognition process based on this theory. The modeling allows the speaker profile to be updated progressively with the new speech sample that is acquired during usage time.

    摘要: In an embodiment, a transmitter includes a transmission path configurable to generate first pilot clusters in response to a matrix, each first pilot cluster including a respective first pilot subsymbol in a first cluster position and a respective second pilot subsymbol in a second cluster position such that a vector formed by the first pilot subsymbols is orthogonal to a vector formed by the second pilot subsymbols, the matrix having a dimension related to a number of cluster positions in each of the first pilot clusters. For example, where such a transmitter transmits simultaneous orthogonal-frequency-division-multiplexed (OFDM) signals (e.g., MIMO-OFDM signals) over respective channels that may impart inter-carrier interference (ICI) to the signals due to Doppler spread, the pattern of the pilot symbols that compose the pilot clusters may allow a receiver of these signals to estimate the responses of these channels more accurately than conventional receivers.
