20110176935 | JET EDUCTOR PUMP - The invention provides a synthetic jet eductor pump that includes a synthetic jet actuator coupled to a fluid conduit. The synthetic jet actuator may include a vibratable membrane, an actuating portion that vibrates the vibratable membrane, a pump chamber coupled to the vibratable membrane, and a pump conduit in fluid communication with the pump chamber such that vibration of the membrane draws fluid into and ejects fluid from the pump conduit to create a net momentum of fluid in a predetermined direction. The fluid conduit may include a jet receiving portion between intake and ejection portions thereof, wherein the jet receiving portion is in fluid communication with the pump conduit. The net momentum of fluid created by the synthetic jet actuator may be communicated to the fluid conduit at the jet receiving portion to create fluid flow in the fluid conduit from the intake portion to the ejection portion. | 07-21-2011 |

20150102745 | LIGHTING CONTROLLER, LIGHTING SYSTEM AND LIGHTING CONTROL METHOD - In a lighting system, sound levels are detected in the vicinity of at least one lighting unit to determine when there is a sound level above a threshold. The illumination provided by the lighting unit is adapted in such a way as to encourage a reduction of noise generation. | 04-16-2015 |
20150282912 | PLAQUE DETECTION USING A STREAM PROBE - An apparatus for detecting the presence of a substance on a surface includes a proximal pump portion and at least one distal probe portion configured to be immersed in a first fluid. The proximal pump portion and the distal probe portion are in fluid communication with one another. The distal probe portion defines a distal tip having an open port to enable the passage of a second fluid therethrough. The apparatus is configured such that passage of the second fluid through the distal tip enables detection of a substance that may be present on the surface based on measurement of a signal correlating to, in proximity to the surface, one or more bubbles generated by the second fluid in the first fluid. A corresponding method of detection includes probing the properties of an interaction zone via outflow of the second fluid medium from the surface. | 10-08-2015 |
