Abstract: An instrument (A) detects in a sample the presence of an analyte. The sample includes electrically readable particles (126) with an agent attached thereto that binds with the analyte or is an analog of the analyte. The instrument includes a port for the sample and a pair of electrodes (25, 30), one of which has a surface portion (30a) with an agent thereat that binds with the analyte or is an analog of the analyte. The electrodes have a first position where they are separated a sufficient distance apart to enable the sample to move between the electrodes and a second position where the electrodes are in close proximity. A detection circuit, including the electrodes, has a first state when the analyte is absent and a second state when the analyte is present. A signaling device provides an indication of the state of the detection circuit.

Abstract: A training device (FIGS. 1 and 2) for a person performing a physical activity wherein the proper performance thereof is related to the proper movement by the person (10). The device comprises a movement sensor (40), a trigger event sensor (50) for sensing the occurrence of a specific physical trigger event, a processor (60), an electronic memory (70), and a protective enclosure (95). The movement sensor (40) provides movement signal values to the processor (60), which is able to store these movement signal values in the memory (70). The trigger event sensor (50) provides trigger event signal values to the processor (60), such trigger event signal values corresponding to the occurrence of the specific physical trigger event near the device (FIGS. 1 and 2). The processor (60) is able to store the trigger event signal values in the memory (70), and evaluate the trigger event signal values (FIGS. 4A-4D, and 90) to determine if the specific trigger event has occurred.
