  • Patent number: 11957475
    Abstract: A biometric information processing device (1) includes a brain wave detecting unit (10), a control unit (20), and a movement assisting unit (30). The brain wave detecting unit (10) detects biometric information in at least one brain region from among a plurality of brain regions that are selectable in accordance with a body part that is a target of function recovery or function improvement. The control unit (20) determines, based on the detected biometric information, at least one activity state in the brain including the location of the brain region(s) that is (are) activated in a subject while attempting to move the body part, and an activation level of such activated brain region(s). When the control unit (20) determines that the at least one activated state of the brain satisfies a predetermined condition, the movement assisting unit (30) executes a predetermined motion to assist movement of the body part.

  • Patent number: 5197129
    Abstract: An input/output device has a processor which processes data strings received by the device. When a data string is received, it is passed to a serial interface and a timing means. The serial interface generates a signal which interrupts the existing processing by the processor and causes the process to start processing of the newly received data string. At the same time the timing means measures the length of the data string and compares it with a predetermined length set by user-controllable data setting means. If the data string length reaches the predetermined length, the processor is triggered to stop processing the new data string and to recommence the processing it was performing prior to interruption. The unprocessed part of the new data string is stored in a memory.In this way, urgent data strings, which are generally short, are processed rapidly and longer data strings are processed after the urgent data strings.

  • Patent number: 5070476
    Abstract: In a sequence controller which is capable of debugging a program including a plurality of sequence programs, a program head code is provided in the program to identify respective sequence programs. In executing the program, the number of sequence programs which are executed is counted by detecting the program head codes associated therewith. Thus, sequence processing can be effected for a predetermined number of sequence programs by stopping the processing of the sequence when the count of the detected program head codes becomes equal to the predetermined number. In addition, it is possible to count only those sequence programs which satisfy a certain condition, such as sequence programs which require a particular operation or relate to a particular control element. In this way, debugging of the program is facilitated.

  • Patent number: 5065307
    Abstract: A built-in insulating element for electrically insulating a process portion from a control object and for transmitting a process result to the control object is provided in the output portion for transmitting the process result of a sequence controller to the control object. Further, a noise preventive element is provided in the output portion for preventing a noise voltage from coming in from the control object side and damaging the insulating element.

  • Patent number: 4807178
    Abstract: Data processing between selected I/O terminals is switched between processing by direct access to the I/O terminals and processing by indirect access through an image memory having a one-to-one correspondence to the I/O terminals.

  • Patent number: 4748553
    Abstract: The states of the signals inputted to a programmable sequence controller or outputted from the programmable sequence controller are stored by a few scanning operations. A check is made to see if a combination of input and output signals which cannot be generated during one scanning operation in the normal operating mode exists in that memory content or not, thereby investigating causes of the occurrence of abnormalities.

  • Patent number: 4502112
    Abstract: In a sequence control apparatus using a microprocessor performing its processing of operation in terms of one word as the unit therefor, a change indicating signal from a process condition detecting or measuring instrument connected to an I/O unit is taken into the microprocessor in a form combined with predetermined pattern data. With the resulting composite data, the contents of those bits of an accumulator in the microprocessor which do not correspond to the change indicating signal can be optionally processed.
