  • Patent number: 12013716
    Abstract: In an operating device, a brake setting unit sets a target braking torque based on a braking torque pattern, and a rotational torque setting unit sets a target rotational torque based on a rotational torque pattern in accordance with information detected by a rotation detecting portion at reference time intervals. A control unit includes a time change adjustment unit. For at least one of the braking torque and the rotational torque, the time change adjustment unit changes the braking torque so that a current braking torque reaches the target braking torque and/or changes the rotational torque so that a current rotational torque reaches the target rotational torque in a predetermined time period greater than the reference time interval.

  • Patent number: 12009581
    Abstract: An antenna device (100) includes an antenna element (102) for emitting and receiving electromagnetic waves, a reflector (104) for reflecting the electromagnetic waves emitted from the antenna element (102), and a substrate (106) on which the antenna element (102) and the reflector (104) are positioned. The substrate (106) defines a main extension plane (108) extending along a horizontal direction (Y) and a lateral direction (X), wherein a vertical direction (Z) extends perpendicular to the horizontal direction (Y) and the lateral direction (X), and thus perpendicular to the main extension plane (108). The reflector (104) has a concave shape (112) in the vertical direction (Z) thereby spatially narrowing in the vertical direction (Z) the electromagnetic waves emitted by the antenna element (102), and has a convex shape (110) in the horizontal direction (Y) thereby spatially widening in the horizontal direction (Y) the electromagnetic waves emitted by the antenna element (102).
