Publication number: 20190226935Abstract: Embodiments of the present disclosure pertain to low frequency pressure sensing. In one embodiment, the present disclosure includes an apparatus comprising a pressure sensor having at least one input and a chamber. The chamber is coupled to the input of the pressure sensor to control pressure variations sensed by the pressure sensor. The chamber comprises a hole, where the hole and the chamber are configured to low pass filter pressure variations at the input of the pressure sensor and filter out pressure variations above about 20 hertz.Type: ApplicationFiled: January 23, 2018Publication date: July 25, 2019Inventors: George Fuh Hwang, Kajiro Watanabe, Danh Le Ngoc

Patent number: 8657707Abstract: An analysis method includes the steps of: measuring a swing of a golf club to which a sensor capable of measuring accelerations in directions of three axes and angular velocities or angles about the three axes is attached; obtaining an index for classifying the swing based on a measuring result of the sensor; and classifying the swing based on the index. The index includes the item (a) or (b): (a) a grip angular velocity at least at one time during a downswing; and (b) a grip velocity at least at one time during the downswing. Preferably, times of an address, a top, and an impact are determined in the analysis method.Type: GrantFiled: September 7, 2012Date of Patent: February 25, 2014Assignees: Dunlop Sports Co. Ltd., Sumitomo Rubber Industries, Ltd.Inventors: Masahiko Ueda, Kajiro Watanabe

Patent number: 6125313Abstract: A control circuit for an air-bag mounted in a motor vehicle comprises an acceleration sensor for producing an acceleration signal indicative of acceleration of the vehicle, an ignition timing circuit for processing the acceleration signal to predict the time when a passenger's head will reach a front surface of the air-bag in fully deployed condition and producing a first air-bag deploying signal in accordance with the predicted time, and a damage discrimination circuit for processing the acceleration signal and judging the need of activation of the air-bag when the cumulative effect of the acceleration exceeds a predetermined limit. The damage discrimination circuit produces a second air-bag deploying signal when judging the need of activation of the air-bag. A so-called AND circuit is further employed which actually activates the air-bag when receiving the first and second air-bag deploying signals concurrently.Type: GrantFiled: April 23, 1998Date of Patent: September 26, 2000Assignee: Kanto Seiki Co., Ltd.Inventors: Kajiro Watanabe, Kazuyasu Kon, Shin-ichiro Tsurushima, Satoru Matsumori, Yasuo Saito, Kunihiro Kaneko, Katsushi Ohneda

Patent number: 5309760Abstract: The peak amplitude values of two different frequency pressure changes produced by the displacement device of a volume sensing arrangement, are obtained and one divided by the other to produce a value indicative of the volume of the unfilled portion of a storage vessel. The contents of the vessel are derived by subtracting the unfilled volume from the vessel capacity. In the embodiments wherein a single pressure sensor is used, the signal is simultaneously filtered with a low pass filter and a band pass filter in order to obtain static and dynamic pressure data. In some embodiments the single sensor is disposed in a chamber in which the displacement means produces two different frequency pressure variations. The chamber is communicated with the storage vessel by a pipe the length and diameter of which are selected to prevent the pressure variations produced by one of the frequencies from being transmitted therethrough.Type: GrantFiled: August 12, 1991Date of Patent: May 10, 1994Assignee: Kanto Seiki Co., Ltd.Inventors: Kajiro Watanabe, Katushi Ohneda

Patent number: 5128656Abstract: A level detecting method and apparatus wherein a tubular member with one end open has a stationary wave generating means located within the tubular member. The stationary wave generating means generates stationary waves having a node or antinode at the open end, whereby a switching signal is provided when the open end of the tubular member is completely closed by a measuring object or when the measuring object approaches the open end.Type: GrantFiled: August 28, 1990Date of Patent: July 7, 1992Assignee: Kansai Automation Co., Ltd.Inventor: Kajiro Watanabe
