    摘要: A technique for dynamically determining the occurrence of a high impedance fault (HIF) independent of load. An HIF algorithm provides the energy value for a given number of samples of the input signal that is phase (load) currents and/or neutral (residual) current. The input signal energy value is multiplied by a factor that ranges from about 110% to about 300% to calculate a threshold energy value and the result of that calculation is stored in a buffer. A HIF detection signal is generated when the energy value determined for samples of the input signal that are the same in number as the given number of samples and taken after the given number of samples is greater than an energy value derived from a predetermined number of the calculated threshold energy values.

    摘要: An improved system and method for providing emergency lighting and directional exit indication in the event of power outage and/or smoke/fire events. The system provides a lighted pathway consisting of discrete points of light, some of which strobe or trace toward the exits and others of which burn steadily for general area emergency lighting. The method consists of detecting the emergency condition and illuminating the appropriate emergency lighting.

    摘要: A stage assembly (10) for moving a device (26) along an X axis and a Y axis includes a stage base (12), a device table (16), a stage mover assembly (18), a measurement system (21), and a control system (22). The stage mover assembly (18) includes a pair X guide movers (82) (84) and a Y table mover (87). The measurement system (21) includes a first X system (100) and a second X system (102). The control system (22) receives the position signals from the measurement system (21) and directs current to the X movers (82) (84) to move the device table along the X axis. The control system (22) can be designed to not skip any servo cycles during switching of position signals.

    摘要: A tissue sample is conventionally visualized in a microscope. A selectively activated convex surface is provided, preferably at the distal end of a rod. This selectively activated convex surface when activated, typically with a laser through an optic light path in the microscope, provides the activated region with adhesive properties. At least one portion of the tissue sample which is to be extracted is identified. This identified portion is contacted with a portion of the selectively activated convex surface on the end of the rod. When the convex surface is activated, typically by exposure to laser light in the footprint of the desired sample, an adhesive transfer surface on the selectively activated convex surface is provided which adheres to the desired cells in the footprint of the desired sample. Thereafter, the adhesive transfer surface is separated from the remainder of the tissue sample while maintaining adhesion with the desired cells. Thus the desired portion of the tissue sample is extracted. The disclosed selectively activated convex surface is preferably utilized to collect desired tissue samples at more than one location on the same slide or from different slides. The collected tissue samples can thereafter be inspected if desired, as collected on the convex surface, and then liberated—as by dissolving the proteins of the samples. This can effectively concentrate rarely occurring cells in order to obtain enough pure material for analysis. A rod having a convex surface with the selectively activated material is set forth as a staple for use with the apparatus and process. Preferred shapes for the convex surface are disclosed as well as a method for coating rods with a resultant rod article.

    摘要: A method and apparatus of gathering by LCM identified cellular material from randorn locations on a tissue sample to designated locations on a transporting substrate enables convenient further processing. A transporting substrate has an identified mapped location for receiving identified cellular material. At least a segment of a selectively activatable coating is placed on the side of the transporting substrate in apposition to the tissue sample at the mapped location. The transporting substrate and sample are relatively moved to place the selectively activated coating at the mapped location in apposition to identified cellular material of the tissue sample which is to be extracted. Thereafter, the selectively activatable coating is activated and impressed or impressed and activated to form an adhesive region on the transporting substrate for adhering to the identified cellular material. Upon removal of the transporting substrate from the tissue sample, identified cellular material adheres to the transporting substrate at the mapped location.

    摘要: The present invention provides a method for detecting whether an alarm circuit is operating outside its sensitivity range, the alarm circuit having a background signal and a preset alarm threshold signal. The method involves: a) multiplying the background signal by a first gain factor to produce a first test signal; b) comparing the first test signal against an alarm threshold signal; c) multiplying the background signal by a second gain factor less than the first gain factor to produce a second test signal; and d) comparing the second test signal against the alarm threshold signal. The alarm circuit is operating outside its sensitivity range when the first test signal is less than the alarm threshold signal or the second test signal is greater than the alarm threshold signal.
