Patent number: 7345956Abstract: A portable electronic device (1) is described, in particular of bracelet watch type, comprising at least first and second display members (8 and 9), means (23, 31) for making measurements of a physical magnitude related to the value of the altitude and a memory zone (26) for storing the measured values of the physical magnitude. The electronic circuits (20) of the device are adapted to control the analog display members, in one mode of operation called the rate of climb mode, so that a first display member (9) indicates the instantaneous rate of change of altitude and the second display member (8) indicates the value of a mean rate of change of altitude against appropriate graduations (10) of the device. Such a device finds its principle application in the field of aeronautical sports.Type: GrantFiled: March 2, 2005Date of Patent: March 18, 2008Assignee: ETA SA Manufacture Horlogère SuisseInventor: Gérald Maurice Matthey

Patent number: 7346418Abstract: Systems and methods for constructing custom orthotics are described. Several embodiments of the system use sensor pads to obtain both static and dynamic three dimensional information concerning the shape or topography of the bottom surface of a patient's foot. The information is analyzed to obtain information useful in constructing a custom orthotic from a selection of basic orthotic shells. Once constructed, the orthotic can modify a patient's gait. One embodiment of the present invention includes a user terminal including a sensor pad connected to a computer, a server configured to analyze three dimensional information acquired by the sensor pad, a manufacturing terminal configured to display the results of the server's analysis of the three dimensional information and a network that connects the user terminal to the server and the server to the manufacturing terminal.Type: GrantFiled: March 8, 2005Date of Patent: March 18, 2008Assignee: Quasar Group, Inc.Inventor: Craig E.

Patent number: 7308380Abstract: A planar pressure-sensitive switch unit has multiple pressure-sensitive switches that are disposed in a longitudinal direction of a bumper cover of a vehicle with given intervals for detecting the number of collision objects. Collision load sensors are disposed between a bumper reinforcement and side members for detecting a total collision load by adding up two outputs. Then, a collision load per a single collision object is computed by dividing the total collision load by the number of collision objects and is compared with a collision load corresponding to a pedestrian. Thus, even when the vehicle collides with multiple objects at the same time, collision with a pedestrian can be properly determined.Type: GrantFiled: October 13, 2005Date of Patent: December 11, 2007Assignee: DENSO CORPORATIONInventor: Takatoshi Tanabe

Patent number: 7273250Abstract: A method and a device are provided for individually adapting the saddle of a two-wheeled vehicle, especially bicycle saddles. The local pressing pressure of the buttocks of a test subject is measured on a adapting device (1) with a measuring saddle (2) and a pressure-measuring device (4) arranged on or in the seat surface at individual points or over a large area and in a localizing manner and evaluated. The two-wheeled vehicle saddle (8) is specifically adapted to the shape of the individual buttocks corresponding to the measuring results and is additionally cushioned where the contact pressure is higher.Type: GrantFiled: June 22, 2002Date of Patent: September 25, 2007Inventor: Claus Oehler

Publication number: 20070162254Abstract: If the diving mode is erroneously entered while travelling at a high altitude, such as when flying in an airplane, the error is detected so that calculating tissue in/out-gassing of inert gases continues. The control unit 50 of the dive computer records the water depth corresponding to the pressure measured by the depth measuring unit 61 together with the elapsed time, determines if the user is moving in a low pressure region based on water entry detection by a water entry detection unit and the depth detected by the depth measuring unit 61, and if the user is determined to be travelling in a low pressure region cancels measuring the water depth, cancels the wrongly selected operating mode, and changes from the operating mode used when diving to an operating used when not diving.Type: ApplicationFiled: January 4, 2007Publication date: July 12, 2007Applicant: Seiko Epson CorporationInventor: Takeshi Hirose
