International Classification:

F04B 43/06
F04B 53/16

Abstract:

A liquid delivery system includes an air elimination assembly disposed in a pathway between a liquid source and a recipient. As its name suggests, the air elimination assembly removes gas from the liquid as it flows between an input port and output port of the air elimination assembly. A magnitude of pressure at the gas output port of the air elimination assembly is controlled to expel gas from the liquid passing from the input port to the output port. The gas expelled from the liquid is outputted from the gas output port. The liquid delivered to the recipient is void of any gases.

International Classification:

F04B 43/073
F04B 53/20

Abstract:

A fluid delivery apparatus includes controller hardware, a diaphragm pump, a positive displacement pump, and a fluid conduit extending between the diaphragm pump and the positive displacement pump. During operation, and delivering fluid to a downstream recipient, the controller hardware draws fluid into a chamber of the diaphragm pump from a fluid source container. The controller hardware applies pressure to the chamber of the diaphragm pump to output the fluid in the chamber of the diaphragm pump downstream through the fluid conduit to the positive displacement pump. During application of the pressure to the chamber and outputting the fluid in the chamber of the diaphragm pump downstream, the controller hardware activates the positive displacement pump to pump the fluid from the positive displacement pump to the downstream recipient.

A61M 5/38

Abstract:

A controller in a fluid delivery system controls magnitudes of pressure in a first volume and a second volume. The first volume is of a known magnitude. The second volume is of an unknown magnitude and varies. The controller estimates a temperature of gas in the first volume and a temperature of gas in the second volume based on measurements of pressure in the first volume and measurements of pressure in the second volume. The controller then calculates a magnitude of the second volume based on measured pressures of the gases and estimated temperatures of gases in the first volume and the second volume.

International Classification:

F04B 43/12
F04B 43/00

Abstract:

A fluid pump device includes an elastically deformable conduit, multiple volume displacement elements, and a controller. During operation, the controller controls movement of the multiple volume displacement elements (such as compensation volume displacement elements and occluding volume displacement elements) with respect to the elastically deformable conduit at different times to cause flow of fluid in the elastically deformable conduit downstream to a recipient. The controller controls movement of the multiple volume displacement elements to volumetrically balance: i) an input flow rate of input fluid conveyed from a fluid source downstream to an input of the elastically deformable conduit, and ii) an output flow rate of output fluid delivered from an output of the elastically deformable conduit downstream to a recipient.

Abstract:

An acoustic probe includes a plurality of acoustic array components separated and spaced apart from each other. Each of the acoustic array components includes: an array of acoustic element circuits disposed contiguous to each other at a first pitch; a plurality of pads each corresponding to one of the acoustic element circuits and formed within a circuitry area of the corresponding acoustic element circuit, the pads being disposed at a second pitch; a plurality of interconnection bumps each corresponding to one of the pads and being disposed in electrical connection with the corresponding pad, wherein the interconnection bumps are disposed at a third pitch; and a plurality of acoustic transducer elements on the interconnection bumps. The acoustic transducer elements are disposed at a fourth pitch. At least two of the first, second, third, and fourth pitches are different than each other.
