Abstract: A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.

Abstract: A method and apparatus for monitoring battery life in a human input device powered by replaceable batteries includes repeatedly measuring battery charge by use of a measuring arrangement forming part of the input device. Battery charge is measured while the input device is in a relatively inactive condition and when it is in an active condition, and a time value is associated with each battery charge measurement. A usage model may be constructed based on the battery charge measurements, and calculation of an expected battery life may be based at least in part on the usage model.

Abstract: One particular implementation conforming to aspects of the present invention takes the form of a method for detecting the end of life of a battery for an electronic device. The method may include calculating the voltage of the battery in an unloaded state, holding the sampled unloaded battery voltage, measuring a loaded battery voltage, calculating the difference between the unloaded and loaded battery voltages and amplifying the calculated difference. Other implementations may take the form of a circuit to perform one or more of the operations of the above method. The circuit may include a sample and hold section and a differential amplifier to provide the amplified difference to a microcontroller for analysis. The microcontroller may also provide a warning or indication to the device or to a user of the device when the battery nears the end of life.

Abstract: Methods for evaluating a pixel signal produced during scanning of a chemical array are provided. In general, the methods involve producing at least two analog signals for a pixel using a multi-gain signal detection system, integrating at least one of these signals, and outputting data representing the pixel.

Abstract: The testing of a multi-touch sensor panel for opens and shorts on its drive and sense lines is disclosed by placing a substantially ungrounded conductor diagonally over the touch sensor panel so that at least a portion of every drive line and every sense line is covered by the substantially ungrounded conductor. Pixels under the substantially ungrounded conductor can have strongly positive pixels, while pixels outside the substantially ungrounded conductor can have negative pixels. With the substantially ungrounded conductor in place, a backdrop of negative pixels is formed, and an image of touch can be obtained. By analyzing the image of touch, any opens and shorts on the drive and sense lines, any shorts between a drive and a sense line, or any open drive and sense lines can be quickly identified against the backdrop of negative pixels.

Abstract: The gain of the ion detector of a mass spectrometer is calibrated by using the ion detector to measure a ratio of the abundances of at least two ion species having a known abundance ratio. The gain of the ion detector is changed until the measured abundance ratio matches the known abundance ratio.

Abstract: Automated methods and systems for determining an in-focus-distance for a position on the surface of a molecular array substrate using a molecular array scanner are provided. A signal from a first position of an array substrate is detected and noise is filtered out of the detected signal using a symmetrical filter to produce an in-focus-distance. In one embodiment, the in-focus-distance is utilized as an estimated in-focus-distance at a second position of the array substrate. The method finds use in maintaining the focus of a light source while scanning the array by the scanner. Also provided are methods of assaying a sample using the methods and systems of the invention, and kits for performing the invention. The subject invention finds use in a variety of different applications, including both genomics and proteomics applications.
