  • Patent number: 10564693
    Abstract: An information processing system is capable of communicating with an external apparatus via a network. The information processing system is capable of operating in at least three operation modes including: a first mode; a second mode, which consumes less power than the first mode; and a third mode, which consumes less power than the second mode and where the communication via the network is not performed. The information processing system includes a mode control section and a second mode processing section. The mode control section, when the information processing system operates in the third mode, shifts the operation mode to the second mode periodically or in accordance with a predetermined time schedule. The second mode processing section performs a communication process via the network as information processing in the second mode.

  • Patent number: 10365175
    Abstract: A surface pressure measuring device includes an abutting plate, a lift, a probe, a piezo actuator and a controller. A pinhole is formed in the abutting plate at an abutting surface that abuts a target. The lift causes the target to abut the abutting surface such that the target is compressed to a predetermined thickness. The probe is inserted through the pinhole to be movable in an axial direction of the pinhole. The piezo actuator holds a state in which a tip surface is flush with the abutting surface as the probe resists a repulsive force received from the target while the lift causes the target to abut the abutting surface. The controller calculates a local surface pressure of the target from a load applied to the probe and an area of the tip surface of the probe.
