Abstract: A predictive shock alert warning system (SA) installed adjacent a body of water and monitoring a voltage level present in the water to alert persons in or about the water the water when the level is approaching, or reaches or exceeds a threshold that will produce a dangerous shock to a person. The system comprises a plurality of probes (1-3) placed in the water, each probe monitoring the voltage level in a zone (Z1-Z3) of water surrounding the probe and producing an output representing the voltage level for the respective zone in which the sensor is placed. An apparatus (100) processes the respective signals from each probe and triggers an alarm (13) when a voltage approaches, reaches or exceeds the danger voltage level.

Abstract: A valve structure includes a valve body on which is mounted a first valve and a second valve. The first valve traverses the valve body at a first position and the second valve traverses the valve body at a second position spaced apart from the first position. The first valve may comprise a fill valve and the second valve may comprise a pressure relief valve. Alternatively, a single valve structure may incorporate both the fill and pressure relief functions. The valve structure may be incorporated with a bladder made of a flexible and elastic material. In this arrangement, the valve body is positioned in a valve receiving opening in the bladder material and is sealed to the bladder material around the periphery of the valve receiving opening so as to define a sealed bladder interior with the bladder material. Such a valve and bladder combination may be used together with a hull tube to form a portion of an inflatable hull for a boat.

Abstract: Thermal control for a controller in a data processing environment is described. In one embodiment, the invention includes detecting a temperature of a semiconductor device at a thermal sensor on the semiconductor device, comparing the detected temperature to a threshold, and generating a high interrupt if the temperature is above the threshold and a low interrupt if the temperature is below the threshold.
