Patent number: 11920536Abstract: A fuel pump system for aircraft includes an auxiliary fuel pump in-line with the primary pump, and an electric motor driving the auxiliary fuel pump at an operational motor speed. The system includes an electric control circuit (ECC) and a pressure sensor to regulate the speed of the electric motor based on the output pressure from the sensor to maintain a constant predetermined output pressure. The system may have additional fault mitigation circuitry configured to automatically switch from a processor-controlled to a fixed voltage as a source of power driving the electric motor at either a regulated speed or a constant fixed speed, respectively. The system may include a switch having user-selectable operational modes, including ECC-controlled mode and a high boost mode selectable if the ECC fails. In high boost mode, the ECC is bypassed to drive the electric motor at a fixed safe speed.Type: GrantFiled: May 17, 2022Date of Patent: March 5, 2024Inventors: Gary Schultz, Conrad P.

Patent number: 11029291Abstract: A system for analyzing a sample includes a chromatographic device, an electrospray source, and a mass resolving device. The chromatographic device is configured to separate components of the sample as a function of retention time within a chromatographic column. The electrospray source is configured to direct a first portion of a flow from the chromatographic device via a waste outlet to a pressurized waste reservoir, direct a second portion of the flow to an electrospray ionization outlet to form a spray, and charge and desolvate the spray to form ions of the components of the sample. A flow rate of the second portion of the liquid flow is substantially determined by a pressure of the pressurized waste reservoir. The mass resolving device configured to receive the ions and characterize the mass-to-charge ratio of the ions.Type: GrantFiled: July 10, 2020Date of Patent: June 8, 2021Assignee: Thermo Finnigan LLCInventors: Gary A.

Patent number: 9247512Abstract: Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.Type: GrantFiled: August 25, 2011Date of Patent: January 26, 2016Assignee: Ubiquiti NetworksInventors: Gary Schultz, Paul Odlyzko
