Patent number: 7456731Abstract: A substrate forming a sensor element is connected to a non-inverting input terminal of an operational amplifier, and a common voltage is applied thereto from a reference voltage supply circuit to fix them to the same potential.

Patent number: 6774776Abstract: A method for alarming a decrease in tire air-pressure, in which rotational numbers of four tires are detected for judging whether any of the tire air-pressures is decreased or not, and issuing an alarm if the internal pressure of a tire is decreased. In an equation for calculating a judged value for detecting deflation of a tire, correction factor function values including a first factor related to lateral acceleration of the vehicle and a second factor related to lateral acceleration and front and rear wheel ratios are subtracted from actually measured values when performing actual running of the vehicle with the tires being set to specific air-pressures. The first and second factors are calculated such that a result of subtraction is approximately close to zero and is stored. It is possible to improve accuracy of detection of deflations of tires by automatically obtaining factors for turning correction after mounting the tires to the vehicle.Type: GrantFiled: July 30, 2002Date of Patent: August 10, 2004Assignees: Sumitomo Rubber Industries, Ltd., Sumitomo Electric Industries, Ltd.Inventor: Minao Yanase

Integrated sensor having plurality of released beams for sensing acceleration and associated methods
Patent number: 6750775Abstract: An integrated circuit and method are provided for sensing activity such as acceleration in a predetermined direction of movement. The integrated released beam sensor preferably includes a switch detecting circuit region and a sensor switching region connected to and positioned adjacent the switch detecting circuit region. The sensor switching region preferably includes a plurality of floating contacts positioned adjacent and lengthwise extending outwardly from said switch detecting circuit region for defining a plurality of released beams so that each of said plurality of released beams displaces in a predetermined direction responsive to acceleration. The plurality of released beams preferably includes at least two released beams lengthwise extending outwardly from the switch detecting circuit region to different predetermined lengths and at least two released beams lengthwise extending outwardly from the switch detecting circuit region to substantially the same predetermined lengths.Type: GrantFiled: February 26, 2001Date of Patent: June 15, 2004Inventors: Tsiu Chiu Chan, Melvin Joseph DeSilva -
Patent number: 6737979Abstract: The invention comprises a micromechanical shock sensor that is formed on the surface of a micro-substrate. A moveable proof mass is formed on the surface with at least one spring connected to the proof mass and the surface. The spring allows the proof mass to move a predetermined distance. Latching means are formed on the surface the predetermined distance from the proof mass. When the sensor is subjected to a sufficient shock, the proof mass moves and contacts the latching means. An indicator means is provided to allow this contact to be readily known by the user.Type: GrantFiled: December 4, 2001Date of Patent: May 18, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Gabriel L. Smith, Lawrence Fan, Ralph E. Balestrieri, Daniel L. Jean

Patent number: 6734802Abstract: There is disclosed an apparatus and method for reducing power consumption in physiological condition monitors that use a memory data storage device that operates in a high power mode when data is being written to the memory data storage device and operates in a low power mode when inactive. The apparatus comprises: 1) a controller for receiving incoming data to be written to the memory data storage device; and 2) a first low power buffer coupled to the controller. The controller stores the incoming data in the first low power buffer until a predetermined amount of incoming data has been accumulated in the first low power buffer and transfers the accumulated predetermined amount of incoming data to the memory data storage device in a single data transfer.Type: GrantFiled: April 22, 2002Date of Patent: May 11, 2004Assignee: iLife Solutions, Inc.Inventors: Michael E. Halleck, Michael D. Halleck, Michael L. Lehrman, Alan R. Owens

Patent number: 6731220Abstract: A strong shaking judgment method and device can use earthquake data recorded at all places in the world to process strong shaking waveform analysis in order to attain strong shaking characteristic parameters. These parameters are used as judgment standards of a strong shaking. A strong shaking judgment method according to the invention is described as follows: first, calculate and analyze every kind of earthquake characteristic parameter, such as a maximum acceleration value, number of times for passing over acceleration threshold, maximum velocity, maximum displacement, shaking energy index and shaking frequency, from acceleration change in a certain preset time frame. Next, use these six parameters to process a strong shaking judgment. A strong shaking judgment device can use a battery module, acceleration sensor module, micro controller module, alarm output module and state display module. The device in coordination with the method mentioned above can process a strong shaking judgment.Type: GrantFiled: April 2, 2002Date of Patent: May 4, 2004Assignee: Industrial Technology Research InstituteInventors: Chung-Chu Chen, Chien-An Chen

Patent number: 6731213Abstract: The present invention is directed to an apparatus, system and method for detecting a user's oral health habits and providing the oral health data over a network for access by a remote user. For example, the user may utilize an oral health apparatus to brush his teeth. During brushing, oral health data may be obtained relating to the user's oral health habits and usage of the oral health apparatus. The oral health data may then be provided over a network to a remote user, such as the user's dental health professional or parent in the case of a young child.Type: GrantFiled: May 31, 2001Date of Patent: May 4, 2004Assignee: Gateway, Inc.Inventor: Michael G.

Patent number: 6711485Abstract: A triggering algorithm contains an accident classification section. The accident classification section senses the type of an accident that occurs. The accident classification section forms probability values for the types of accident in question when an accident cannot be classified unambiguously. By reference to the type of accident or the probabilities that are determined, weighting factors are formed and are taken into account in the calculation of the criterion and/or of one or more comparison thresholds. The triggering algorithm is modular and can thus be easily standardized on a module-specific basis.Type: GrantFiled: September 4, 2001Date of Patent: March 23, 2004Assignee: Siemens AktiengesellschaftInventors: Michael Feser, Oskar Leirich
