  • Patent number: 9545205
    Abstract: A method for preventing dozing off, comprising the steps of: a measurement step measuring human heartbeats; a decision step (S4 to S8) generating a trigger, hereinafter referred to as a “drowsiness trigger”, for indicating occurrence of drowsiness when a state in which a time interval between adjacent heartbeats, hereinafter referred to as a “heartbeat interval”, is longer than the previous heartbeat interval consecutively occurs; and a warning step (S9) giving a warning to prevent dozing off when the drowsiness trigger is generated.

  • Patent number: 8355811
    Abstract: A clothing simulation apparatus precisely determines clothing pressure for bringing a clothing into tight contact with a human body. A fitting part 22 divides a paper pattern model into a plurality of elements, imparts dynamic characteristics shown by a fabric model to each element, deforms the paper pattern model by solving the motion equation of each element using a finite element method, and then fits the clothing virtually to a human body model. The fitting part 22 sets a temporary model to cover a predetermined section of the human body model, deforms the paper pattern model to bring the paper pattern model into contact with the temporary model, and thereafter deforms the paper pattern model to bring the paper pattern model into contact with the human body model.
