Publication number: 20240099596Abstract: A gatekeeper electronic signal can be generated by a patient sensor and/or in an intermediate device, such as an electrical cable, that is separate from a patient's physiological information electronic signal. The gatekeeper signal can be generated to indicate to a computer monitor that the sensor and/or cable is of the type that is compatible with, and/or usable with, such computer monitor, and/or that the sensor and/or cable is properly attached to the computer monitor. The gatekeeper signal can be created by an ambient temperature sensor on, or in electrical communication with, the patient monitor, and/or the gatekeeper signal can be created by a gatekeeper electronic signal generator to simulate an ambient temperature value. The gatekeeper signal can be separate from an electronic signal or plurality of signals that include patient physiological information, and the gatekeeper signal may not include any patient physiological information.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Timothy John Hughes, Lina Derderian

Publication number: 20220189624Abstract: A patient monitor configured to receive patient-information electrical signals from an invasive patient sensor and a minimally invasive patient sensor, the patient monitor including a base unit and a detachable user interface unit for displaying hemodynamic parameters determined by the base unit. The base unit and user interface unit can be docked together, tethered together through a cabled connection, or physically separated from one another using wireless communication to transmit and receive information. The base unit and the user interface unit may pair before the user interface unit displays data to link the base unit with the user interface unit. The patient monitor can be configured to switch between invasive and minimally invasive monitoring of hemodynamic parameters of a patient, using invasive measurements to calibrate minimally invasive measurements.Type: ApplicationFiled: March 7, 2022Publication date: June 16, 2022Inventors: Tom McCall, David Snider, Timothy John Hughes, Lina Derderian, James Cobb, Alison D.

Patent number: 8950194Abstract: In order to minimize the loss of cryogen during transportation of superconductive magnet systems, or indeed at any time that the refrigerator is turned off, part of the boil-off gas is directed from the cryogen vessel through the refrigerator interface and past the refrigerator to cool the refrigerator. Some of the heat conducted along the refrigerator into the system is intercepted and removed by that part of the boil-off gas. The heat load onto the cryogenic vessel is thereby reduced, which in turn reduces the boil-off of cryogen from the cryogenic vessel. This part of the boil-off gas is then vented from the system along with the remainder of the boil-off gas, for example to leave the cryogenic liquid vessel via the access neck.Type: GrantFiled: May 12, 2005Date of Patent: February 10, 2015Assignee: Siemens PLCInventors: Timothy John Hughes, Stephen Paul Trowell, Keith White
