Abstract: A method and apparatus for managing water consumption and preventing damage to a fluid supply system in a house or structure is disclosed. The water management system includes a water management device coupled between provided fluid flow, pressure, and temperature sensors, and a shut-off valve and a drain valve. The device includes flow control means for opening the shut-off valve when flow is detected at any flow sensor and closing the shut-off valve when flow is undetected. The device also includes flow timers which have a selected operational period for each flow sensor and which close the shut-off valve if the operational period of a flow sensor is exceeded. The device also includes temperature timers for closing the shut-off valve and opening the drain valve when a temperature at or below a minimum temperature is detected by the temperature sensor for a selected maximum temperature detection time period.

Abstract: A system for controlling fluid flow between a first point and a second point on a fluid line is disclosed. The system includes the first valve located at the first point on the fluid line to permit forward fluid flow from the first point to the second point on the fluid line and for closing to prevent such forward fluid flow. The system also includes flow sensors for detecting forward fluid flow at the second point and opening the first valve when such forward fluid flow is detected. The flow sensors also close the first valve when fluid flow at the second point stops. The system further includes a second valve located at the second point for opening and closing to control forward fluid flow at the second point. The system prevents forward fluid flow if a break in the fluid line occurs between the first and second points by preventing the first valve from opening.

Abstract: A method and apparatus for establishing consistent image brightness, especially for a multiple video image seamless display, is provided by storing a set of smoothing factors, one for each detail element of each image, in a memory. Upon projection, the smoothing factors are applied to the brightness components of the associated detail elements of each image. The smoothing factors are selected by applying a standard curve, coarse tuning major curve parameters in response to the appearance of the projected multiple image display, and fine tuning smoothing factors for specific detail elements, the locations of the detail elements being indicated by a cursor on the display.
