    摘要： 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.

    摘要： Optical scanner system approaches are described in which novel focusing approaches are provided. A control algorithm accounts for geometric variation of successive scans in opposite directions across a microarray slide or substrate in order to provide optimized focus. The feedback approach taught may involve PI or PID terms. In either type of control approach, a projected slope of the slide is calculated and followed back and forth outside a scan region of the array in exiting and entering fully adaptive focusing zones, respectively. During turn-around, the system may track a setpoint between the periods of following the extrapolated slope. Also provided are methods of using the subject system in a biopolymer array based application, including genomic and proteomic applications.

    摘要： System for large dynamic range light detection. In one aspect, the system includes a hybrid counting/integrating system for processing a signal from a photomultiplier tube. In another aspect, large dynamic range is achieved in a cascaded detector system utilizing at least one asymmetric beam splitter for delivering a larger fraction of incident light to one photomultiplier tube and for delivering a smaller fraction of the incident light to another photomultiplier tube.

    摘要： A design method for an asynchronous sequential circuit that employs synchronous design techniques wherein a synchronous sequential circuit is designed to perform a desired function. A terminating state for the synchronous sequential circuit is then defined wherein the terminating state occurs before a transition to an idle state in the synchronous sequential circuit. A circuit is provided for latching at least one asynchronous input for the asynchronous sequential circuit and a circuit is provided for generating a synchronous clock that drives the synchronous sequential circuit such that the synchronous clock is enabled by a latched asynchronous input and is disabled by the terminating state of the synchronous sequential circuit.

    摘要： 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.
