  • Patent number: 10795326
    Abstract: The present disclosure relates to an information processing apparatus, a method, and a program capable of causing a system to efficiently learn a method of controlling a person. A control learning system calculates a reward based on an input objective state of a control target and a state of the control target based on a sensing result of the control target. The control learning system performs reinforcement learning using the calculated reward and the state of the control target to select a better action for bringing the control target closer to the objective state. The control learning system executes the selected action for the control target. For example, the present disclosure can be applied to a control learning system including a terminal and a cloud system.

    Abstract: Disclosed herein are non-fried potato chips that are produced without frying in oil to reduce an oil content but have a crispy texture and good meltability in the mouth, which cannot be sufficiently achieved by conventional non-fried potato chips, and are therefore comparable to potato chips produced by frying in oil. The inside of the non-fried potato chips is sufficiently puffed, and the non-fried potato chips have a number of pores. More specifically, the non-fried potato chips have 10/mm2 or more holes with a short diameter of 20 ?m or more and a porosity of 35% to 65% when their vertical sections are observed.

  • Patent number: 10741205
    Abstract: The present invention addresses the problem of providing an output device, which can reduce the impact on an object to which power is supplied even when an output unit continuously fails to supply a voltage. To solve the problem a brake mechanism includes a contact member and a variable unit. The contact member may be brought into contact with a read head that reads information recorded as an information stream stored in a medium that moves relative to the read head. The variable unit changes a contact state between the contact member and the read head when the information representing the displacement between the position on the medium read by the read head and the position in the recorded information stream exceeds a prescribed range.
