Patent number: 10481252Abstract: A sensor device includes a radio wave sensor and a signal processor. The signal processor includes an identifier and a noise remover configured to remove, from a second sensor signal, at least one frequency component determined as a noise component by the identifier. The identifier compares a signal intensity of each of the frequency components with one or more signal intensities of other frequency components. When a signal intensity of a first frequency component is greater than signal intensities of one or more second frequency components located in the vicinity of the first frequency component by an extent exceeding a threshold range, the identifier determines the first frequency component as the noise component.Type: GrantFiled: May 23, 2017Date of Patent: November 19, 2019Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Tatsuo Masuda, Tadashi Murakami, Shigeo Gotoh

Patent number: 6094718Abstract: A programmable controller includes a BPU that executes first-class instructions, a CPU that executes second-class instructions, and a memory that is shared by the BPU and the CPU and stores a program, which is formed of a combination of first-class and second-class instructions. The programmable controller also includes a judgment-data storage section that stores judgment data for judging whether a second-class instruction is a skippable instruction or not, and a skip processing section that judges whether the operation result of the preceding instruction satisfies a skip condition or not. If judging that the operation result satisfies the skip condition, then the skip processing section judges whether a current instruction of the second class is a skippable instruction or not, based on the above judgment data, and skips the current instruction without transferring control right to the CPU, if the current instruction is a skippable instruction.Type: GrantFiled: February 19, 1998Date of Patent: July 25, 2000Assignee: Matsushita Electric Works, Ltd.Inventors: Youichi Tanaka, Futoshi Nakai, Tatsuo Masuda

Patent number: 6073507Abstract: A shift control unit is provided in an electric-power-assist transmission which offers good operatability. A shift disabling unit employs a neutral-position detecting unit, a vehicle-speed judging unit, an engine-rotational-speed judging device, an OR circuit and an AND circuit. The neutral-position detecting unit is used for outputting an "H"-level signal to indicate that a gear is placed at a neutral position. The vehicle-speed judging unit generates an "H"-level signal for a speed of a vehicle equal to or higher than 10 km/h. On the other hand, the engine-rotational-speed judging device generates an "H"-level signal for a rotational speed of an engine equal to or higher than 3,000 rpm. The OR circuit generates an "H"-level signal when the vehicle-speed judging unit generates an "H"-level signal or the engine-rotational speed judging device generates an "H"-level signal.Type: GrantFiled: September 11, 1998Date of Patent: June 13, 2000Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Atsuo Ota, Satoru Narita, Tatsuo Masuda
