Inventor: BERTHON-JONES MICHAEL
IPC: A61B5/087
Filed: 1997-09-23
Granted: 2011-02-01
Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor receives an airflow signal from a pressure transducer coupled to a port at a mask.  The microprocessor controls a servo that in turn controls the fan motor and thus the pressure of air delivered by the blower. The blower is coupled to a subject's mask by a conduit. The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

Abstract: After-cooking darkening is a gray-black discoloration of the potato tuber, formed after cooking by the oxidation of an iron-chlorogenic acid complex. Cinnamic acid 4-hydroxylase (C4H) is a key enzyme involved in the biosynthesis of chlorogenic acid. The full-length c4h gene was cloned and sequenced from both genomic DNA and cDNA of Russet Burbank tuber tissue by PCR and 5' and 3' RACE. The gene expression levels of c4h were examined by Northern hybridization in potato cultivars varying in susceptibility to after-cooking darkening. Results suggest that there is a relationship between the levels of c4h gene expression and the degree of after-cooking darkening in potato tubers.

Title: Pressure detector and pressure detecting method
Inventor: KANEKO MITSURU
IPC: A61M1/36
Filed: 2003-01-30
Granted: 2011-09-13
Abstract: A pressure detector having a pipe inner pressure receiving opening section comprising a fluid passage for transporting fluid and a diaphragm hermetically sealing an opening made in one side face of the fluid passage, and a pressure detecting section coupled with the pipe inner pressure receiving opening section through the diaphragm and detecting physical variation of the diaphragm, characterized in that the diaphragm is provided loosely at the opening, and the pressure detecting section comprises at least a pressure detector, a load transmitting means having one end connected with the diaphragm and the other end touching the pressure detector, and means for loading the pressure detector. Since a fluid being measured is not exposed directly to air, possibility of clogging the circuit with a blood clot can be reduced; and since a stress load on the diaphragm is reduced, irreversible creep deformation of the diaphragm can be prevented; thereby allowing the pressure detector to perform continuous measurement stably with high accuracy for a long time.
