  • Patent number: 7313925
    Abstract: An atomizer for thermal management system for efficiently thermally managing one or more heat producing devices. The atomizer for thermal management system includes a housing having a coolant passage and a dispensing end, an orifice within the dispensing end, and an actuator manipulating a plunger within the housing. The plunger includes a head that is sealable within a recessed portion of the orifice to open or close the orifice. The coolant passes through the coolant passage into the orifice for spraying upon a heat producing device. The actuator may reciprocate so that the coolant spray emitted through the orifice is pulsating. The pulsing frequency may be increased to increase cooling or decreased to decrease cooling of the heat producing device.

  • Patent number: 7275604
    Abstract: A sprinkler system includes a control panel including a processor, a power supply source, and a memory including software instructions for automatically toggling the system between operating and non-operating modes. The control panel includes controls mated to the processor that generate and transmit a user input control signal thereto. The processor executes a control algorithm for enabling the user to override the system. Sensors are spaced along a perimeter of the building structure, are camouflaged and shaped as an outdoor ornamental lawn art such as insects and amphibians, and generate and transmit an RF detection signal to the control panel, identifying an ambient temperature. Lawn and fire sprinkler assemblies are positioned about the building structure. The lawn and fire sprinkler assemblies are mated to the control panel and are independently operable.

  • Patent number: 7141215
    Abstract: The present invention is an aromatic evaporator consisting of a base, a heater, a heat conduction aluminum plate, a constant temperature controller, a plug, a ceramic carriers and a cover. The plug sets inside the base to deliver D.C. power; the heater converts the electricity from the plug into heat; the heat conduction aluminum plate adhered to the heater directly evens the heat; the constant temperature controller contains the electric conduction switch and the memory alloy plate connected with the heat conduction aluminum. When the memory alloy plate is straight, the electric conduction switch is switched off and stops the heater from heating. When the temperature reduces, the memory alloy plate is curved by external force and switches on the electric conduction switch, making the heater reheat. The memory alloy plate of the constant temperature controller controls the heater to heat intermittently, making the heater heat at constant temperature.

  • Patent number: 6843199
    Abstract: An odor-emitting port is provided in a housing member composed mainly of an inorganic material. An odorous material is contained in the housing member, and the odor-emitting port is sealed with a low-melting metal to constitute a heat-sensitive odor-emitting component. In this heat-sensitive odor-emitting component, as soon as the temperature of a heat generation site has reached a predetermined value, the low-melting metal is instantaneously melted down to open the odor-emitting port through which the odorous material contained in the housing member is immediately spread around the odor-emitting component. Therefore, the odor-emitting component is highly sensitive to temperature. Further, since the housing member is formed of an inorganic material, the long-term stability can be improved.

  • Patent number: 6579563
    Abstract: A fluid dispensing system for monitoring a weight of a fluid dispensed by a fluid dispenser. A first monitoring device determines a first flow characteristic, for example, pressure, of the pressurized fluid flowing through the fluid dispenser; and a second monitoring device determines a second flow characteristic, for example, viscosity, of the pressurized fluid flowing through the fluid dispenser. A monitor control produces an output representing a weight of the fluid dispensed by the fluid dispenser as a function of the first and second flow characteristics. The monitor control also stores values relating to a size of an orifice through which the pressurized fluid is dispensed and a density of the pressurized fluid. The weight value is determined as a function of the orifice size and the density values. The present invention also includes a method of monitoring a weight of a fluid being dispensed by a fluid dispenser.
