  • Patent number: 11614641
    Abstract: Eyewear having: an optical module; an input unit; a sensing unit; a storage unit that stores at least conditions that change optical properties of the optical module; and a control unit that performs electric control of the optical module, in accordance with a set mode, by using electric control. The set modes include: a first mode in which the control unit electrically controls the optical module on the basis of a condition stored in the storage unit and a detection value for the sensing unit; and a second mode in which the control unit electrically controls the optical module on the basis of instructions received by the input unit. The conditions stored in the storage unit are updated on the basis of the detection value for the sensing unit when the input unit has received an instruction in the second mode.

  • Patent number: 11294204
    Abstract: Provided is a sensor module that includes: a casing; a contacted part that is disposed so that at least a part thereof is exposed to the outside of the casing and that has conductivity; and a detection part that has an electrostatic capacitance type detection pad and that is disposed inside the casing. The detection part further includes a conductive plate provided so as to correspond to the detection region of the detection pad, the contacted part being electrically connected to the conductive plate. This configuration makes it possible to provide a sensor module that is highly sensitive to contact with an object, and that prevents damage to the detection pad caused by contact with the object.

  • Publication number: 20210132418
    Abstract: This eyewear comprises: a frame; an input unit which is disposed in the frame and accepts a first instruction operation and a second instruction operation that are different from each other; an optical module which is held in the frame and has an optical characteristic that changes by electric control; and a control unit which changes the optical characteristic of the optical module by selectively executing an upper-class function by the first instruction operation, and selectively executing a lower-class function by the second instruction operation. Consequently, the eyewear enabling execution of a larger number of functions with a simpler manipulation can be provided.
