  • Publication number: 20210295053
    Abstract: To accurately recognize observed objects. An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.

  • Patent number: 11027920
    Abstract: Provided is a rack management system, including a processor and a storage unit. The storage unit stores information indicating positions of sections included in an area in which storage racks that store articles can be arranged. One of the storage racks can be arranged in each of the sections. At least one of the sections is surrounded by other adjacent sections without an aisle to convey the storage racks therebetween. The processor classifies the sections into sections assigned ranks indicating a degree of efficiency of an operation to convey the storage racks placed therein to a predetermined working area, and one or more empty sections into which, if there is a need to move one or more other storage racks in order to convey a storage rack placed in a given section, the other storage racks that were moved are placed, and outputs results of the classification.

  • Patent number: 10596994
    Abstract: A grill bracket, a rear end portion of which is fixed to a shroud, is provided below a fascia upper member which is provided in front of a bonnet (engine hood). A front-side portion of the grill bracket is configured as an impact absorbing structure (a rib structure with ribs, for example) which extends forward along a back face of the fascia upper member. A front end portion of the impact absorbing structure is configured to be bent downward. Impact absorption for a relatively-small load which is applied from an upward side is attained by downward-bending deformation of the grill bracket (the front-side portion). Impact absorption for a relatively-large load which is applied from a forward side is attained by a bracing operation as well as downward-bending deformation of the front-side portion.

  • Publication number: 20180151709
    Abstract: An n-type drift layer DRL formed on a buffer layer BUF in a semiconductor device (SiC-IGBT) is configured so as to have (c1) an n-type first drift region DRL1 formed on the buffer layer BUF and (c2) an n-type second drift region DRL2 formed on the first drift region DRL1, (c3) an impurity concentration of the first drift region DRL1 is made lower than an impurity concentration of the buffer layer BUF and higher than an impurity concentration of the second drift region DRL2, and (c4) the first drift region DRL1 is made thinner than the second drift region DRL2. By forming the drift layer DRL so as to have a stacked structure as described above, an electric field on a surface on an emitter region side can be lowered at the OFF time of the semiconductor device even if a high voltage is applied. Moreover, at the time of switching, noises can be reduced since a carrier-stored region can be ensured.
