    摘要： Embodiments include a buoyant wave energy converter. In an embodiment, the wave energy converter comprises an upper chamber having a first fluid reservoir and a first gas pocket, and a lower chamber having a second fluid reservoir and a second gas pocket. In an embodiment, an injection tube is between and fluidly coupled to the upper chamber and the lower chamber, where the injection tube is to impel a fluid from the second fluid reservoir into the first fluid reservoir when the upper chamber, the lower chamber and the injection tube oscillate about a waterline with the upper chamber adjacent to the waterline and the lower chamber submerged below the waterline and vertically beneath the upper chamber. An effluent tube is fluidly coupled to the upper chamber and the lower chamber, where the effluent tube is to return the fluid from the first fluid reservoir to the injection tube.

    摘要： A fluid pump for generating a fluid stream (55) is provided. The fluid pump includes a first actuator (20) with a first vibration element, a second actuator (30) with a second vibration element, and a power source that is connected to the first actuator and second actuator to supply energy to the first actuator and second actuator. The fluid pump further includes a controller that is connected to the power source and controls the power source to vary the energy supplied to the first actuator and second actuator. The first actuator (20) and the second actuator (30) are arranged opposite to each other so that a first movement direction of the first vibration element is inclined with respect to a second movement direction of the second vibration element. The controller controls the power source so that the first vibration element moves towards the second actuator and the second vibration element moves towards the first actuator in a synchronous manner and thereby cyclically soaks in a fluid from the surroundings and ejects the fluid in a directed manner.

    摘要： The present disclosure is drawn to inertial pumps. An inertial pump can include a microfluidic channel, a fluid actuator located in the microfluidic channel, and a check valve located in the microfluidic channel. The check valve can include a moveable valve element, a narrowed channel segment located upstream of the moveable valve element, and a blocking element formed in the microfluidic channel downstream of the moveable valve element. The narrowed channel segment can have a width less than a width of the moveable valve element so that the moveable valve element can block fluid flow through the check valve when the moveable valve element is positioned in the narrowed channel segment. The blocking element can be configured such that the blocking element constrains the moveable valve element within the check valve while also allowing fluid flow when the moveable valve element is positioned against the blocking element.

    摘要： A piezoelectric blower includes an outer casing and a blower main body. The outer casing houses the blower main body. The blower main body includes a top plate, side plate, first vibrating plate, piezoelectric element, intermediate plate, second vibrating plate, side plate, and bottom plate and has a structure in which they are laminated in sequence. The top plate, side plate, and first vibrating plate define a columnar first blower space. The second vibrating plate, side plate, bottom plate define a columnar second blower space. The distance from a neutral plane of the piezoelectric element in the thickness direction to a surface of the second vibrating plate, the surface being near the piezoelectric element, is longer than the distance from the neutral plane to a surface of the first vibrating plate, the surface being near the piezoelectric element.

    摘要： The present invention is directed to a cooling system (1) for electronic components (4). The cooling system (1) comprises means (7) for producing cyclic air pressure fluctuations, wherein the electronic components (4) are distanced from the pressure producing means (7). In the vicinity of the electronic components (4) are situated means (5), preferably restrictions like holes, which are affected by the cyclic air pressure fluctuations, and which produce cyclic air jets (6). The air jets (6) affect the surface of the electronic component (4), and since the air jets (6) originate directly in the vicinity of the electronic components (4), an efficient heat transfer is affected. Preferably, the pressure producing means (7) actuate a pressure Pc inside a chamber (2), and turbulent air jets (6) are produced through holes (5) of a substrate (3), onto which electronic components (4) are mounted.
