Publication number: 20240082511Abstract: A fluid flow system and a method for detecting air bubble and liquid are provided. The fluid flow system comprises a force sensor configured to monitor at least one of an air bubble or an occlusion in a flow tube. The fluid flow system comprises a controller to execute the method. The controller is configured to monitor an output signal of a force sensor of the fluid flow system, and the output signal comprises an Alternating Current (AC) component and a Direct Current (DC) component, and detect a change in the output signal to a new output signal based on a number of transitions to the new output signal, and a time duration of the new output signal. The controller compares the change in the output signal with one of a predefined number of transitions or a predefined time and determines a new threshold when the change in the output signal exceeds one of the predefined number of transitions or the predefined time.Type: ApplicationFiled: November 22, 2023Publication date: March 14, 2024Inventors: Kuna V S R KISHORE, Abhishek JOSHI, Kumaran S.

Patent number: 11867583Abstract: Disclosed are pressure sensors including a die and an application-specific integrated circuit (ASIC) mounted on a top surface of a substrate. The pressure sensor can define an inner volume and a bottom opening configured to abut the substrate. The die and ASIC are mounted on the top surface of the substrate within the inner volume. The substrate defines a first aperture therethrough and the die defines a second aperture therethrough in a direction along an axis perpendicular to the substrate, the first aperture and the second aperture being aligned. Metallic barrier(s) disposed on a bottom surface of the substrate, circumferentially about the first aperture, can be at least partially coated with solder mask to reduce or prevent flow of unwanted materials past the metallic barriers and through the first aperture. The substrate can include electrical connection pads on the bottom surface configured to be in communication with a daughter board.Type: GrantFiled: November 3, 2022Date of Patent: January 9, 2024Assignee: Honeywell International Inc.Inventors: Manjesh Kumar B, Alistair David Bradley, Josh M.
