Abstract: A flashlight includes a flashlight head assembly that may be used with either one or two batteries. For use with one battery, a body receives a battery therein and the flashlight head assembly is secured to the body. For use with two batteries, an extension unit is secured to the body and the flashlight head assembly is secured to the extension unit. A switch assembly disposed in the body and electrically connected with the flashlight head assembly controls the delivery of power to the flashlight head assembly.

Abstract: A method and apparatus wherein traditional design methodologies directed toward obtaining minimized component costs are largely set aside in favor of mass customization, reduced design and ownership costs, and shorter design cycles. The distributed architecture contemplates widespread distribution of monitoring and control functions for most device-specific hardware under the direction of a CPU module. In implementation of the distributed architecture, various component modules are placed in communication with the CPU module through at least one and preferably multiple communication busses.

Abstract: A displacement sensing device transduces deflection of a body disposed around a conduit into complementary signals indicative of the amount of displacement experienced by the conduit. The displacement sensing device includes a cuff and a sensor disposed on an outer periphery of the cuff, and may further include a controller in communication with the sensor, such that the controller receives signals from the sensor and compares the current signals to a normal operating range. The normal operating range may be predetermined or derived based on trends, thereby allowing the controller to adapt to any product disposed within the conduit. Once the range is determined, the controller is able to discern when the product system is out of product, or operating at elevated pressures. In alternative embodiments, a pumping device or an inductor may generate a recognizable wave pattern that may be monitored to determine if the product system contains product.
