  • Publication number: 20160221445
    Abstract: A motor driving apparatus includes a driving unit configured to drive a motor according to a torque inputted by a rotation input from a human being; and a controller configured to control driving of the driving unit according to a relationship between an accumulated value of first amounts that correspond to the rotation input from the human being and an accumulated value of second amounts that correspond to rotation of a rotating object driven by the motor. The controller may be further configured to cause the driving unit to suppress driving of the motor when an accumulated difference that is calculated by subtracting the accumulated value of the second amounts from the accumulated value of the first amounts is equal to or less than a predetermined threshold.

  • Publication number: 20160182694
    Abstract: Embodiments described herein relate a mobile communication device and techniques to suppress deterioration of antenna characteristics. The mobile device includes metallic members that are disposed around, or in portions of a casing of the mobile device. The metallic member is grounded directly to a ground plane of the mobile device at a first predetermined position. The grounded metallic member forms a stub line that cancels a flow of electric current though the metallic member. Furthermore, the metallic member is also connected to the ground plane, at a second predetermined location, via a resonant circuit. The mobile device is capable of adjusting a phase of the antenna current flowing through the device, when the mobile device is being operated by a user, and thus suppresses deterioration of antenna characteristics in certain desired frequency bands.
