Abstract:
An energy harvesting apparatus includes a housing that includes an internal portion filled with dielectric liquid in a vacuum state, first and second electrode portions that are disposed to face each other in the housing and configured to be polarized with different polarities, a first layer that forms a path along the internal portion of the housing to allow the dielectric liquid and bubbles generated from the dielectric liquid to flow through the path, and a second layer configured to insulate the first and second electrode portions from the housing. The bubbles are generated from the dielectric liquid when thermal energy is applied to the housing. The first and second electrode portions may change a dielectric constant of the dielectric liquid when the bubbles move between the first and second electrode portions to generate current.
Abstract:
A terminal apparatus includes a battery configured to supply operation power for the terminal apparatus and be rechargeable, a regulator configured to regulate and output the operation power supplied from the battery to have a predetermined level, a connector configured to include a plurality of terminal pins and receive charging power for the battery from an external charging source through the plurality of terminal pins, and a connector cap configured to couple with the connector and have a pattern for electrically connecting a first pin and a second pin among the plurality of terminal pins while coupling with the connector to prevent electric current of the battery from being consumed. A product including the terminal apparatus is released in a state that the cap for electric connection between the terminal pins is coupled to the connector, preventing a standby electric current of the battery from being consumed during distribution.
Abstract:
A display apparatus is provided. The display apparatus includes a display panel, a chassis configured to support the display panel, a backlight unit configured to be installed on the chassis, and an electricity generator configured to use the backlight unit as a heat source to generate electricity. The electricity generator includes a heat transfer unit which contacts the backlight unit, at least one heat storage unit which contacts the heat transfer unit, and at least one thermoelectric device comprising a heat generator and a heat absorber contacting the heat transfer unit. The at least one thermoelectric device absorbs heat, which is generated from the backlight unit, through the heat transfer unit in response to the backlight unit being driven and absorbs heat from the at least one heat storage unit through the heat transfer unit in response to the backlight unit not being driven.
Abstract:
A method of controlling a remote controller comprising a jog shuttle that provides a first control of moving a control knob along a plate surface of the remote controller and a second control of turning the control knob. The method includes transmitting, to an electronic apparatus, a display command of displaying a setting menu screen for the electronic apparatus on a display of the electronic apparatus in response to one of the first control and the second control being performed; and transmitting, to the electronic apparatus, a moving command of moving a cursor pointing to one of menus displayed on the menu screen in response to the other one of the first control and the second control being performed.
