The second temperature sensor measures a second temperature of the hydraulic fluid within a cooling flow stream downstream of an outlet of the pump. The controller determines a value of a temperature rise of the hydraulic fluid across the pump as a difference between the first temperature and the second temperature, and obtains an expected range for the temperature rise across the pump based on a speed of the pump. In response to the value of the temperature rise being outside of the expected range, the controller generates a maintenance message for communication off-board the aircraft, indicating the pump is degraded.Type: ApplicationFiled: October 14, 2022Publication date: April 18, 2024Applicant: THE BOEING COMPANYInventors: Morgan M.

Publication number: 20240125678Abstract: The present invention addresses the problem of providing a new compound that binds specifically to intracellular and/or extracellular vesicles, a cellular vesicle stain, and a method for fluorescent staining of cellular vesicles. The problem can be solved by a compound represented by formula (1). (In formula (1), R1 represents H, a C1-C6 alkyl group, a hydroxy group, an amino group, or a carboxy group. R2 represents H, a C1-C18 alkyl group, a C1-C18 alkoxy group, a halogen element, NO2, or N(CH3)2. R3 and R4 each independently represent H or CH3. However, R3 and R4 may bond to each other to form a ring, in which case R3 and R4 are CH2. 1 represents 1 or 2; m represents 0 or 1; and n represents 1, 2, or 3. Z represents a fluorescent group.Type: ApplicationFiled: January 19, 2022Publication date: April 18, 2024Inventors: Hiroshi TAKEMORI, Kyoji FURUTA, Yoko MORITA
