Patent number: 11969999Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes an ID line, a fire line, a discharge path, a memory element, and a latch. The memory element is electrically coupled to the fire line and the discharge path. The latch disables the discharge path in response to a first logic level on the ID line and enables the discharge path in response to a second logic level on the ID line.Type: GrantFiled: January 20, 2023Date of Patent: April 30, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Boon Bing Ng, Mohan Kumar Sudhakar

Patent number: 11642883Abstract: In some examples, a circuit includes a data line, an input line, a first memory element, and a decoder to receive an address and to enable the first memory element for access in response to the address. The selector is responsive to the data line to select the first memory element, where the selector is to select the first memory element responsive to the data line having a first value, and where the data line is to communicate data of a second memory element in response to the second memory element being enabled for access. The input line is to communicate data of the first memory element in response to the first memory element being selected by the selector.Type: GrantFiled: June 10, 2022Date of Patent: May 9, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Boon Bing Ng, Rui Pan, Mohan Kumar Sudhakar, Brendan Hall

Patent number: 11351776Abstract: In some examples, a circuit for use with a memory element and a nozzle for outputting fluid, includes a data line, a fire line, and a selector responsive to the data line to select the memory element or the nozzle. The selector is to select the memory element responsive to the data line having a first value, and to select the nozzle responsive to the data line having a second value different from the first value. The fire line is to control activation of the nozzle in response to the nozzle being selected by the selector, and to communicate data of the memory element in response to the memory element being selected by the selector.Type: GrantFiled: July 6, 2017Date of Patent: June 7, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Boon Bing Ng, Rui Pan, Mohan Kumar Sudhakar, Brendan Hall
