Abstract: An energy-saving device is electrically connected between an output terminal of an electric power and an input terminal of a load and includes a current dividing unit connected with the load in parallel, and a voltage dividing unit connected with the load serially. The current dividing unit has an input terminal electrically coupled to an output terminal of the load and an output terminal electrically coupled to the input terminal of the load. The voltage dividing unit has an input terminal electrically coupled to the output terminal of the electric power and an output terminal electrically coupled to the input terminal of the load. Thus, the voltage dividing unit drops the voltage of the load applied by the electric power, and the current dividing unit increases the current flowing into the load, so that the energy-saving device achieves an energy-saving purpose.

Abstract: A microplasma source and a sterilization system including the same are disclosed. The microplasma source includes: a microplasma-generating unit including: a gas transmission chamber having a first inlet and a first outlet wherein the first inlet is used to import a first gas; a protection and heat dissipation chamber of which a side is connected to the inner wall of the first outlet; a dielectric inner tube having a second inlet and a second outlet and penetrating through the protection and heat dissipation chamber, wherein the second inlet is communicated to the gas transmission chamber; an electrode arranged outside at the second outlet and located in the protection and heat dissipation chamber; and a hollow metal tube disposed in the gas transmission chamber and the dielectric inner tube and having a third inlet and a third outlet, wherein the third inlet is used to import a second gas.

Abstract: The present invention includes a monitoring end device and a warning end device. When the monitoring end device is placed on a laptop computer or connected with the laptop computer, if the monitoring end device is displaced by vibration or a distance detection unit loses a wireless signal of a transmission or receiving unit, then a warning sound will be sent out through a loud speaker. At this time, the warning end device also produces vibration and a warning sound through a vibration unit and a loud speaker, thereby warning and informing a user of a safety condition of the laptop computer.

Abstract: The present invention discloses a cuff which includes a wrap band. A surface of the wrap band is provided respectively with a first Velcro strip and a second Velcro strip made of a different material than the first Velcro strip that the first Velcro strip and the second Velcro strip can be fastened and fixed together. An interior of the wrap band is provided with a bladder which is connected with more than one joint pipe. The joint pipes are connected with a pressure regulation device by which a pressure of the bladder is increased and decreased repeatedly to result in a volume change that wounded tissues and surrounding unwounded tissues are depressurized and pressurized, thereby achieving an effect of reducing a risk of necrosis to the wounded tissues and the surrounding unwounded tissues.

Abstract: A bell side structure for a stethoscope head of the present invention is related to a design for a stethoscope head, and more particularly to a bell side structure fabricated from a metallic diaphragm. The metallic diaphragm includes a metallic membrane, and superior conductibility of metallic material is used to increase conduction efficiency of sound waves by the bell side, thereby increasing diagnostic effectiveness of the stethoscope head.

Abstract: A hose coupling device includes a flexible hose member having a bore formed by an inner peripheral surface, and having one or more longitudinal ribs extended into the bore, for engaging with the inner peripheral surface of the hose member, and for preventing the bore of the hose member from being completely blocked, and for allowing water to flow through the bore of the hose member even when the hose member is twisted. A coupler may be coupled to water reservoir and includes a mouth engageable into the hose member. The coupler includes one or more longitudinal grooves to receive the longitudinal ribs of the hose member, and to anchor the hose member to the mouth of the coupler.
