20120308863 | WOUND TYPE BATTERY AND METHOD FOR FABRICATING SAME | 12-06-2012 |
20130076998 | OPTICAL DEVICE - Disclosed is an optical device which includes: optical components configured to be electrically actuated such that light transmission states are variable; a driver circuit for the optical components; a power source unit for driving the optical components; rims for supporting the optical components; temples having front and rear ends and connected at the front ends to the rims; and earpieces formed at the rear ends of the temples. The power source unit includes a secondary battery, and a charge/discharge circuit for controlling charge and discharge of the secondary battery. The secondary battery is provided near the rear end of the temple or in the earpiece. | 03-28-2013 |
20130100363 | OPTICAL DEVICE - Disclosed is an optical device which includes: an optical component configured to be electrically actuated such that a light transmission state is variable; a driver circuit for the optical component; a power source unit for driving the optical component; a rim for supporting the optical component; a temple having front and rear ends and connected at the front end to the rim; and an earpiece formed at the rear end of the temple. The power source unit includes a secondary battery, a power switch, a power switch control portion, and a use-status sensing portion for sensing the status of use by a user of the optical device. The power switch control portion performs control to turn off the power switch when the use-status sensing portion does not sense any use by the user of the optical device. | 04-25-2013 |

20130120706 | OPTICAL DEVICE AND CHARGING SYSTEM INCLUDING THE SAME - An optical device including: one or more optical components configured to be electrically actuated such that light transmission states are variable, a driver circuit for the optical components, a power source unit for driving the optical components, a pair of rims for supporting the optical components, a pair of temples having front and rear ends and being connected at the front ends to the pair of rims, and a pair of earpieces formed at the rear ends of the pair of temples. The power source unit includes a secondary battery, and a power receiver coil for charging the secondary battery. The secondary battery includes a case made of a non-magnetic material. | 05-16-2013 |
20130316209 | BATTERY AND MANUFACTURING METHOD OF THE BATTERY - A battery includes a first electrode plate, a second electrode plate, a separator interposed between the first and second electrode plates, a closed-end cylindrical metal case accommodating these three elements, and a sealing member sealing an opening of the metal case with an insulating member interposed therebetween. The first and second electrode plates are wound with the separator interposed therebetween to form a wound electrode group. A center axis portion of the wound electrode group is substantially the same as a center axis of a cylinder of the metal case, and contains no power-generating element. A first current collector lead coupled to the first electrode plate extends toward the opening of the metal case, and joined to an inner sidewall surface of the metal case. A second current collector lead coupled to the second electrode plate extends toward the opening of the metal case, and joined to the sealing member. | 11-28-2013 |
20140242448 | CYLINDRICAL BATTERY - Provided is a small-sized cylindrical battery in which improvement in battery characteristics and improvement in long-term reliability and safety are both realized. | 08-28-2014 |
20150077664 | OPTICAL DEVICE - Disclosed is an optical device which includes: an optical component configured to be electrically actuated such that a light transmission state is variable; a driver circuit for the optical component; a power source unit for driving the optical component; a rim for supporting the optical component; a temple having front and rear ends and connected at the front end to the rim; and an earpiece formed at the rear end of the temple. The power source unit includes a secondary battery, a power switch, a power switch control portion, and a use-status sensing portion for sensing the status of use by a user of the optical device. The power switch control portion performs control to turn off the power switch when the use-status sensing portion does not sense any use by the user of the optical device. | 03-19-2015 |
