Abstract:
A photoelectric element package with temperature compensation includes a substrate, and a first light-emitting element, a second light-emitting element, a photosensitive element, and a drive element disposed on the substrate, all of which are disposed in an internal space formed by a first casing joined with a second casing. Alternatively, the second light-emitting element and the photosensitive element are disposed in an internal space of a third casing. By adding the second light-emitting element, the photosensitive element can sense the light emitting intensity accurately in the absence of other interferences, so as to feed back the current operating state of the light-emitting element. A temperature compensation function is achieved by a laser driver, so as to reduce the influence of temperature on the light-emitting element, such that the light-emitting element emits light in an accurate intensity.

Abstract:
A remote control positioning system adopting radio frequency (RF) positioning technology and displaying positioning information of the remote control on a display is provided. When a user is searching for the remote control, the remote control positioning system can be used to obtain the positioning information from a screen of the display, and the user can rapidly determine a position of the remote control according to environment images captured by an image capturing module. Thus, the time for searching by the user is saved, and an effect of precise tracking is realized as well.
Abstract:
A first housing and a second housing of a handheld device are capable of sliding with respect to each other such that the first and the second housings can be positioned in different using positions and thus the handheld device can be configured at corresponding using statuses. The first housing includes a first magnetic element and the second housing includes a plurality of second magnetic elements aligning along a direction. The second magnetic elements having one polarity and the second magnetic elements having another polarity are disposed alternately. When the second housing slides on the first housing to a position where the first magnetic element faces a second magnetic element with opposite polarity, the handheld device is configured at a corresponding using status.
Abstract:
The present invention provides a remote controlling system using an optical fiber. The remote controlling system is for controlling N electronic equipments located in a situation. The remote controlling system according to the invention includes a receiving unit and a transmitting unit. A radiation signal receiver of the receiving unit is for receiving a first radiation signal. According to the first radiation signal, a first controlling module of the receiving unit is for driving a light-emitting device to emit a control light signal to the optical fiber. The control light signal is transmitted over the optical fiber and then received by a photo-detector of the transmitting unit. According to the received control light signal, a second controlling module of the transmitting unit is for driving M radiation signal transmitters to emit M second radiation signals, so as to control one of the N electronic equipments.
Abstract:
A compact pen has a top barrel, a controlling device securely mounted inside the top barrel, and a bottom barrel telescopically connected with the top barrel by means of threading engagement between the controlling device and the bottom barrel. An ink container having a tip is disposed inside the top barrel and the bottom barrel and further extends into the controlling device, whereby the tip is able to retract into the bottom barrel when not in use and the length of the compact pen is short in order to be conveniently carried around.

Abstract:
A handheld device includes a row of lighting elements configured at the side of its top body that faces a keypad of its bottom body for illuminating the keypad when the two bodies slide away for use. The lighting elements projects light in a direction nearly parallel with the keypad and toward the surface of the keypad, and illumination of the keypad is therefore accomplishable in various environmental conditions. The lighting elements may also be used for illuminating the keypad or displayed with different strength or bright and dark periods based on the ambient brightness, and based on the charging rate of the handheld device's rechargeable battery when the handheld device is being charged.
