Patent number: 8446294Abstract: This invention allows for the precise determination of an aircraft's landing conditions and whether an aircraft has experienced a hard landing that exceeds the allowable design loads of the aircraft's landing gear. The system comprises a computer that measures signals from an inertial measurement unit (IMU) at high data rates (e.g. 100 Hz) and also records signals from the aircraft avionics data bus. The computer compares the output from the inertial measurement unit's accelerometers against at least one predetermined threshold parameter to determine whether the aircraft's three dimensional landing deceleration is safely within the design allowances or other regulatory limitations, or whether the landing event needs further investigation.Type: GrantFiled: August 11, 2009Date of Patent: May 21, 2013Assignee: Messier-Dowty Inc.Inventor: R.

Publication number: 20130118227Abstract: Provided are a device (10) and a method for measuring the crispness of a food product. An item to be measured (22) comprising a porous food product is broken apart by causing the blade of a knife (14) to penetrate into the item. A vibration detector (18) attached to the knife (14) detects crack vibrations from cracks that form when the item to be measured (22) is broken apart. In a computer (20), the small crack vibrations of a predetermined vibration power or less that are included in the crack vibrations within an individual cracking duration time are extracted from the detected crack vibrations. Crispness is measured on the basis of the number of extracted small crack vibrations counted (number of cracks).Type: ApplicationFiled: July 20, 2011Publication date: May 16, 2013Applicants: GIFU UNIVERSITY, NISSHIN SEIFUN GROUP INC.Inventors: Michihiro Sakakibara, Takahisa Nishizu

Publication number: 20130111972Abstract: Testing methods and equipment are provided for fast, non-destructive testing of the quality of seal and/or integrity of a package. According to certain embodiments, dynamic impact characterization is used to determine whether a loss of pressure due to a leak in the package occurs. The methods and equipment can be used in-line with product packaging processes. According to one embodiment, an initial pressure is applied to a package under test. A region of the package is impacted with a force sufficient to create a disturbance to the package while not destroying the package by using an impacting rod. Force sensors/transducers contact with the package and spaced a distance away from the impact region of the package detect a force signature from the impact. The existence of a leak is determined by evaluating the force signature.Type: ApplicationFiled: July 18, 2011Publication date: May 9, 2013Applicant: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC `Inventor: Ghatu Subhash

Patent number: 8408041Abstract: The invention relates to a fall detection system, for detecting human fall incidents. The detection system comprises a sensor module to be worn by a user, for collecting motion data of his body, for instance acceleration data; first evaluation logic for identifying a potential fall incident on the basis of an impact observed in the acceleration data; and second evaluation logic for verifying that the sensor module is actually worn by the user, at least around the time of said impact, to prevent the system from raising an alarm if only the sensor module has fallen. The second evaluation logic may comprise free fall detection means for evaluating the acceleration data on characteristics which are typical for a free falling object, such as one or more full rotation and/or a free falling phase, during which the magnitude of the acceleration data is relatively stable and small.Type: GrantFiled: April 15, 2008Date of Patent: April 2, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Warner Ten Kate, Ingrid Christina Maria Flinsenberg, Ningjiang Chen, Sheng Kim, Stephan Schlumbohm, Rudie Bernardus Maria Schonenberg
