Abstract: A personal monitoring device of the present disclosure has a sensing device that detects motion of a user and a global positioning system (GPS) that executes queries to identify a current location of the user. In addition, the device has logic that stores motion data indicative of motion of the user detected by the sensing device and adjusts a rate of location queries executed by the GPS based upon the stored motion data indicative of motion.

Abstract: An amplifier having a switchable common gate gain buffer is disclosed. In an exemplary embodiment, an apparatus includes a plurality of selectable gain channels that provide constant input impedance at a common input to receive an input signal and generate an output signal having at least one of selected gain and current characteristics. At least two gain channels utilize transistors having different transconductance values. The apparatus also includes at least one impedance network coupled to at least one gain channel to provide the constant input impedance.

Abstract: A personal monitoring system of the present disclosure has a cellular network and a sensing device. The sensing device has an interface that couples the sensing device to the cellular network and to a user for sensing a location of the user. The sensing device transmits data indicative of the location to a computing device via the cellular network. The system further has logic that determines a baseline elevation based on a first location of the user and a change in elevation at a second location of the user from the baseline elevation. The logic transmits data indicative of the baseline elevation and the change in elevation to the computing device via the cellular network.

Abstract: A personal monitoring system of the present disclosure has a network and a sensing device. The sensing device has a network interface for coupling the sensing device to the network and is coupled to a user for sensing raw data at a discrete time related to the user. Additionally, the system has logic that associates a timestamp with the raw data at the discrete time and stores the raw data as raw history data indicative of a plurality of raw data from discrete times. Further, the logic determines, based upon the raw history data, whether an event has occurred.

Abstract: A device and a method are disclosed for creating a virtual keyboard, mouse, or position detector. The device is an electronic keyboard that detects the position of a user's finger. The position of a user's fingers are detected by sending out a light beam parallel to the surface of, for example, a desk, and then detecting the position of a user's finger as the light beam is blocked by the finger. The position and movement of the user's fingers determine which key is to be struck or in which direction to move the pointer.
