Patent number: 11035814Abstract: A method of microfluidic detection can include detecting, using an impedance sensor, an impedance of a fluid to indicate whether a threshold amount of fluid has been received in a reservoir of a microfluidic chip. The method can include initiating a test performed by the microfluidic chip on the received fluid when the threshold amount of fluid has been received.Type: GrantFiled: January 30, 2015Date of Patent: June 15, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeremy Sells, Chantelle E. Domingue, Manish Giri, Melinda M. Valencia

Patent number: 10875018Abstract: A fluid testing cassette may comprise a microfluidic channel having a constriction and a micro-fabricated integrated sensor within the constriction. In one implementation, the constriction is less than or equal to 30 ?m. In one implementation, the cassette further comprises a nozzle connecting the microfluidic channel to the discharge reservoir, wherein a thermal resistor expels fluid within the microfluidic channel into the discharge reservoir.Type: GrantFiled: January 30, 2015Date of Patent: December 29, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Manish Giri, Chantelle E. Domingue, Robert J. Moline

Patent number: 10725019Abstract: Example implementations relate to coagulation sensing. For example, a microfluidic chip for coagulation sensing may include a microfluidic channel, an outlet at an end of the microfluidic channel having an air interface, and an impedance sensor located within the microfluidic channel and within a particular proximity to the air interface, the impedance sensor to determine a stage of a coagulation cascade of a blood sample flowing through the microfluidic channel to the impedance sensor.Type: GrantFiled: January 30, 2015Date of Patent: July 28, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Melinda M Valencia, Chantelle E Domingue, Jeremy Sells, Manish Giri, Sadiq Bengali
