A camera module for an optical touchscreen includes a body part and a light emitting device coupling part. The body part may be disposed on one side corner of a touch region, provided with a light receiving hole at a portion thereof facing a center of the touch region, and provided with a lens mounted to correspond to the light receiving hole and an image sensor disposed to receive light collected through the lens. The light emitting device coupling part may be formed on at least one side of the body part that faces each edge of the touch region, and configured to be coupled to a light emitting device.

Camera module for optical touchscreen

Display screen or a portion thereof with a graphical user interface

The present invention relates to a camera module which senses the position of an on object touching a touch surface of an optical touch screen. The camera module comprises one or more lenses, an optical path converting unit, and an image sensor. Each of the lenses is arranged such that the angle of view for the direction vertical to the touch surface is smaller than the angle of view in the direction horizontal to the touch surface. The optical path converting unit reflects light converging through the lenses in the direction vertical to the touch screen. The image sensor is arranged behind the lenses and in the direction horizontal to the touch surface so as to receive the light reflected by the optical path converting unit.

Camera module for an optical touch screen

The present invention relates to an optical touch screen which can recognize touch coordinates when the screen is touched by a finger, a touch pen, or the like. The optical touch screen comprises units for generating infrared light sources. A control unit calculates coordinates of an object being touched on the touch screen based on data detected by the infrared cameras.

Optical touch screen

A portable terminal having a first body, a second body moveable with respect to the first body, and a swivel assembly that connects the second body to the first body is provided. The swivel assembly is configured to allow the second body to rotate in a substantially planar motion with respect to the first body between a closed configuration and an open configuration. The swivel assembly includes a spacing unit displacing the second body from the first body while the second body is rotated with respect to the first body.

Portable terminal

Hydrogen generating apparatus that is capable of controlling the amount of hydrogen generation. The hydrogen generating apparatus has an electrolyzer, a first electrode, a second electrode, a switch, which is located between the first electrode and the second electrode, a flow rate meter, which measures an amount of hydrogen generation in the second electrode, and a switch controller, which receives a set value, compares the amount of hydrogen generation measured by the flow rate meter with the set value, and controls an on/off status of the switch. The amount of hydrogen generation can be controlled by use of on/off time and/or on/of frequency of the switch.

A fuel cell is disclosed. The fuel cell can include a membrane electrode assembly (MEA), converting a chemical energy to an electrical energy; a first end plate, stacked on one surface of the MEA and formed with a first coupling hole; a second end plate, stacked on the other surface of the MEA; and a protrusion, formed on the second end plate such that the protrusion penetrates the first coupling hole and an end part of the protrusion protrudes a surface of the first end plate, and the end part being transformed such that the end part couples the first end plate and the second end plate. With the present invention, the fuel cell can reduce contact resistance between elements and its overall size and prevent a leak of fuel. In the manufacturing process, the end plates and the MEA can be arranged, improving reproducibility and repetition for mass production.

Fuel cell

A fuel cell power generation system is disclosed. The fuel cell power generation system in accordance with an embodiment of the present invention includes: a stack, which produces electrical energy by reacting hydrogen with oxygen and in which the hydrogen is supplied as fuel and the oxygen is in the air; a hydrogen tank, which supplies fuel comprising hydrogen to the stack; and a heat transfer tape, which transfers heat generated from the stack to the hydrogen tank. The fuel cell power generation system can improve the efficiency of supplying hydrogen by supplying waste heat generated from the stack to the hydrogen tank through the use of the heat transfer tape without a heat supplying device and be applied to a mobile device due to the reduced volume of the fuel cell power generation system.

Fuel cell power generation system

A fuel cell and a method of manufacturing the fuel cell are disclosed. A method of manufacturing a fuel cell by electrically connecting a first cell and a second cell that are coupled over both sides of a membrane with a predetermined gap between the first cell and the second cell, where the first cell and the second cell each has an anode on one side and a cathode on the other side, may include perforating a hole in the membrane between the first cell and the second cell, and electrically connecting the anode of the first cell with the cathode of the second cell through the hole using a conductive member. This method does not entail unnecessary increases in volume or complicated flow paths, and the method can reduce electrical resistance while simplifying the peripheral equipment.
