Patents by Inventor Katsufumi Yoshida

Katsufumi Yoshida has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9998155
    Abstract: The invention relates to a signal processing device, a signal processing method, an information processing program and a recording medium, which removes wide-range frequency noise. In a signal processing device (10), a cycle of acquiring a signal from a sensor is a data acquisition cycle, which is shorter than a cycle of forwarding time sequence data from which noise is removed to a controller, that is, a forwarding cycle.
    Type: Grant

  • Patent number: 8887000
    Abstract: A safety device of the invention includes at least one of an input unit having one or more input terminals and an output unit having one or more output terminals, a testing unit having one or more test terminals, a rewritable nonvolatile memory configured to store setting information of a terminal specification which can be set from outside via the tool, and wherein the terminal specification of the one or more test terminals included in the testing unit is determined in accordance with the setting information of the terminal specification.

  • Patent number: 8090993
    Abstract: This invention enables setting of a diagnosis algorithm of a safety device to be easily carried out. A slice I/O unit stores a plurality of diagnosis algorithms each corresponding to a different safety device in an ASIC, and stores specifying information for specifying a diagnosis algorithm to use of the plurality of diagnosis algorithms in a register of the ASIC. The slice I/O unit performs diagnosis of a connected safety device using the diagnosis algorithm specified by the specifying information stored in the register of the plurality of diagnosis algorithms. The diagnosis algorithm to use can be selected by selecting a number, and the like, which is preferable as a setting process at a setting tool device can be facilitated and a human error does not occur.

  • Patent number: 7555353
    Abstract: This invention provides an input device of safety unit which enables an error diagnosis result referred to in a process of input processing for generating a control data from raw input signal to be referred by a side using the control data also in a safety unit such as a safety master and safety slave. An input device contains a function of outputting status data indicating the error diagnosis result referred to when input signal is converted to control data and the control data obtained by the conversion in pair, so that when the logical value of the control data is “LOW”, whether it originates from that the raw logical value is “LOW” or that “LOW” is compulsorily set due to an error in the terminal can be determined from the logical value of the status data.
