摘要： A portable biofeedback apparatus and method for simultaneously gathering information regarding more than one type of musculoskeletal stress. The apparatus has at least two different types of user-selectable sensors for converting different kinds of musculoskeletal activities into electrical signals. An analog-to-digital converter samples the electrical signals at predetermined rates. A memory receives and stores the digital signals. A processor centrally controls the collection, sampling, display and transmittal of the digital data. Magnitudes of the digital signals are simultaneously and in real-time graphically portrayed as a function of time.

摘要： A device and method for diagnosing shorts and fault conditions in electrical circuits such as heating, ventilation, and air conditioning (HVAC) control circuits. The device includes a positive temperature coefficient (PTC) member to protect the electrical circuit from overcurrent conditions during diagnosis. The device also includes a light emitting diode (LED) and resistor electrically connected in parallel across the PTC member. An overcurrent condition causes the resistance of the PTC member to rise dramatically, creating a potential difference across the PTC member and lighting the LED. The invention also includes a method for locating a short in an HVAC control circuit using the short locating device.
