Patent number: 10460529Abstract: A computer system having a display generation component and one or more input devices displays a representation of a virtual three-dimensional object in a user interface region. In response to an input for rotating the object, when the input corresponds to a request to rotate the object about a first axis, the object is rotated by an amount that is determined based on a magnitude of the input and is constrained by a limit on the movement restricting rotation by more than a threshold amount. When the input corresponds to a request to rotate the object about a second axis, the object is rotated relative to the second axis by an amount that is determined based on a magnitude of the input, wherein, for an input with a magnitude above a respective threshold, the device rotates the object by more than the threshold amount of rotation.Type: GrantFiled: September 27, 2018Date of Patent: October 29, 2019Assignee: APPLE INC.Inventors: Jonathan R.

Patent number: 9966767Abstract: A charge control device uses external electricity to charge a plurality of battery devices. A constant current source uses the external electricity to generate and adjust an output current amount to a constant target value. A selector selects one battery device from the plurality of battery devices and supplies output current from the constant current source to the one battery device. A measurer measures an amount of actual current flowing from the constant current source to the one battery device. An instructor monitors a measured value provided by the measurer and instructs the selector, when the measured value meets a condition for a reduction of charging current amount to be regarded as having occurred, to change a destination to which the output current of the constant current source is supplied from the one battery device to a different battery device.Type: GrantFiled: April 22, 2015Date of Patent: May 8, 2018Assignee: Konica Minolta, Inc.Inventors: Yuhei Tatsumoto, Tomonobu Tamura, Satoshi Teshima
