  • Publication number: 20230331082
    Abstract: A four-wheel-drive vehicle includes: an engine as a driving source; a right front wheel and a left front wheel as main driving wheels and a right rear wheel and a left rear wheel as sub-driving wheels that are driven by a driving force of the engine; a driving force transmission device that transmits part of the driving force of the engine to the right rear wheel and the left rear wheel; and a control device that controls the driving force transmission device. The control device is configured to, when the four-wheel-drive vehicle moves straight forward, adjust the driving force transmitted to the right rear wheel and the left rear wheel by the driving force transmission device so as to maintain a state where the magnitude of a front-rear force generated in the right front wheel and the left front wheel is greater than zero.

  • Patent number: 11783129
    Abstract: An interactive control system according to an embodiment includes one or more hardware processors configured to function as a detection unit, a conversion unit, first and second estimation units, and an attribute determination unit. The detection unit detects an input keyword from input information. The conversion unit converts the input information into information including the input keyword and the input-keyword-excluded context information. The first estimation unit estimates, from the context information, at least a first estimate information piece in which the input keyword's first attribute is associated with a first likelihood of the first attribute. The second estimation unit estimates, from the input keyword, at least a second estimate information piece in which the input keyword's second attribute is associated with a second likelihood of the second attribute. The attribute determination unit determines the input keyword's attribute based on the first and second estimate information.

  • Publication number: 20220331793
    Abstract: In a recovery device, a removing target such as a blood cell is removed from a liquid sample in a sample container using a first filter unit, and a microorganism is filtered from the liquid sample using a second filter unit. A controller causes a first switch to block a flow channel in response to a sensor detecting a bubble. A medium flows from a second connection unit of the second filter unit toward a first connection unit. Thus, the microorganism filtered by the second filter unit is recovered by a recovery container together with the medium.
