摘要:
A variable area heat sink has a first heat sink area and a second heat sink area. A bridge is connected to the first heat sink area and includes a bi-metallic portion operable to connect and disconnect with the second heat sink area in response to a temperature change in the bridge which is sufficient to distort the bi-metallic portion from a first shape to a second shape. The first heat sink area may be installed in a computer chassis adjacent a first heat producing component. The second heat sink area may be installed in the chassis adjacent a second heat producing component. The combination of heat sink areas may be enlarged or reduced in size due to the coupling or uncoupling.
摘要:
A toilet seat incorporating a laser pointing device for creating a target to increase accuracy during standing urination. Several embodiments of decorative and/or functional lighting may also be combined in various embodiments of the toilet seat. Power may be supplied from an internal battery pack or, optionally, from an external power supply connected to the power grid. Numerous versions of sensors and/or controls may be implemented to switch one or more features on or off depending upon such factors as ambient light levels, the proximity of a person to the toilet seat, etc. In some embodiments, timers may be used to control one or more features. Ancillary devices such as audio annunciatiors, audio message generators, and fragrance generators may also be included.
摘要:
A filtration system is provided that may be used in remote areas; a pump for forcing water through a filter is powered by at least one solar panel and may force water through the filter in either direction; in a filtering operation, water is passed in a forward direction until a pressure sensor measures that the water pressure on the filtered water side of the filter has dropped to a predetermined level, at which point water is forced through the filter in the reverse direction. A controller is configured to control the operation of the pump.

A novel electro-opto-mechanical assembly is provided. The electro-opto-mechanical assembly comprising: a first wafer, the wafer having a top and bottom surface; at least one optical element disposed on one surface of the first wafer; at least one discrete opto-electronic transducer element disposed on the bottom surface of the first wafer and in optical communication with the optical element; and an optical waveguide; wherein the first wafer and the optical element form an optical relay which relays light between the discrete opto-electronic transducer and the optical waveguide and thereby forms an efficient optical coupling between the discrete opto-electronic transducer and the optical waveguide.
摘要:
A pump system for a pressure sewer system, comprising a pump, a cutter and an electric motor configured to drive the pump and the cutter; the pump system comprises a current sensor that measures the electric current provided to the motor and the controller stops the operation of the motor if the current drawn by the electric motor exceeds the predetermined threshold.
摘要:
The present invention provides a fish attracting composition. Previously fish sex hormones were considered only to have a role in sexual reproduction, however the present invention shows that these hormones can be used to induce feeding behaviour in fish. In particular a fish attracting composition is disclosed which contains at least one fish sex hormone which functions as a sex pheromone, however a synthetic nature similar version thereof may alternatively be used. In particular, a fish composition containing the composition 12,20β-dihydroxy-4-pregnen-3-one is shown, this for inducing feeding behaviour in carp.
