Abstract:
Embodiments of the present invention may provide a step, rock guard, handyman jack storage and even jack lift point system that can be made for most 4×4 vehicles. One product may resolve individual problems that may become apparent once a lift kit and larger wheels are installed on a 4×4 vehicle. Products can be made to fit two-door Jeeps, four-door Jeeps, Trucks, SUV's, or the like.
Abstract:
A spa is provided with a water temperature modification system for heating the water contained in the spa tub. The spa includes a control system that operates with the water temperature modification system to achieve a spa water temperature at a time preset by a user. The control system preferably uses a clock, a temperature measuring device, and a database to preheat the spa water to the set temperature in an efficient manner just prior to the time set by the user.
Abstract:
A spa is provide with a heat pump for both heating and cooling the water contained in the spa tub. The heat pump uses the existing water pump of the hydrotherapy system to circulate the water through the water heat exchanger of the heat pump. Condensation produced by the heat pump is pumped into the spa tub. Components of the heat pump and water pump are acoustically isolated for noise reduction. Electronic noise reduction may be implemented. Co-generated heat is used to heat the air to produce warm therapeutic bubbles and to feed an ozonator. In addition, an auxiliary electrical resistance heater is arranged in combination with the heat pump for rapid water heating.
Abstract:
A spa tub includes a control system that operates with a water temperature modification system to stabilize the spa water at a set temperature. In a preferred embodiment, the water temperature modification system is a heat pump. The stabilized temperature provides safety to users of the spa.
Abstract:
A spa is retrofit for use with a heat pump for both heating and cooling the water contained in the spa tub. The heat pump uses the existing water pump of the hydrotherapy system to circulate the water through the heat exchanger of the heat pump.
Abstract:
A method and system for modeling water flow of a watershed restoration project. The modeling system allows a user to create a graphical representation of the different areas of a development site design. The graphical representation shows the water flows between the different areas. The user may also specify the attributes of each area, such as rate of infiltration, runoff coefficient, size, rate of evapotranspiration, and so on. The modeling system can simulate the impact of rainfall on the development design. The simulation determines the inflow of water to each area and determines the outflow of water for each area. The results of this simulation can be used to evaluate the development design and adjust the design to achieve the desired cost-benefit balance of the watershed protection criteria of choice.
Abstract:
A vehicle wheel suspension has a composite, transversely oriented, leaf spring which is vertically thick and stiff in end regions extending inward from each end of the spring past the vehicle body support area but is vertically thin and compliant in a middle region between the end regions. The spring is constructed of a long, longitudinally aligned fiber and resin composite which is split at each outer end of the middle region into upper and lower horizontal layers separated by a core having a tapered inner end and extending through the end region. The inserts provide the additional vertical thickness in the end regions without widening the middle region and may be made of a different material, such as a short, randomly oriented fiber and resin composite. The spring thus flexes easily in the heave mode, in which the thin middle region of the spring flexes vertically in opposition to each end. But the center of the spring resists flexing in the roll mode, in which the ends of the spring move vertically in opposition to each other and the spring attempts to flex in the thick end regions. The spring thus provides a high spring rate in roll with a low spring rate in heave for a high roll ratio. The flexing of the spring in the middle, and thus the roll ratio, is additionally enhanced by providing pivoting and longitudinally translating body mounts for the spring. Two specific mount structures are described: a hybrid mount in which mount members above and below the spring each comprise a high modulus member with a rounded surface adjacent the spring affixed to a low modulus member providing longitudinal compliance, and a link mount providing pairs of fore and aft links pivoted at both the spring and body ends.
Abstract:
The present invention provides a recondensing service neck for a cryostat. A service neck tube (22) provides access to the interior (10) of the cryostat. A recondensing surface is provided (44) for recondensing liquid cryogen boiled off from a liquid cryogen (12) within a cryostat; and a recondensing refrigerator (30) is provided for cooling the recondensing surface to below the boiling point of the cryogen.
