摘要:
A joint socket device for memory cards provides a common lower base with an upper covering to offer a common space for receiving a smart media card (SMC), a multimedia card (MMC), a secure digital memory card (SD) and a memory stick (MS). The joint socket device is available for being inserted with four different memory cards without a need of offering four different socket devices so as to save contact points thereof, reduce the size occupied thereof, and facilitate the use thereof, respectively.

A direction sensor includes two electrode guides, at least six contact pins, a moving member and a signal processing circuit. The two electrode guides are formed with a gap. The two electrode guides and the at least six contact pins define a space. The moving member is restricted to move in the space. The two electrode guides are electrically connected to one signal terminal of the signal processing circuit, respectively, and the at least six contact pins are electrically connected to another signal terminal of the signal processing circuit, respectively. A direction is sensed after the moving member moves in the space according to a sensed direction and contacts with the contact pin corresponding to the sensed direction below, so that one of the electrode guides and the contact pin corresponding to the sensed direction below form a sensing signal loop through the moving member.
摘要:
A common socket device for memory cards is a common inserted base with an upper cover to offer a common space for receive a smart media card, a multimedia card, and a secure digital memory card. The common base may be inserted by two or three memory cards without a need of providing two or three kinds of different socket device. Therefore, contact points in the common socket device is reduced substantially, a less volume of the common socket device is obtained comparing to the gross volume of two or three conventional socket devices, and it enhance the convenience for the user.

An offline setup recording device used in an electronic apparatus is illustrated. When the electronic apparatus is power on, the total energy storage unit is charged by a power supply through the unidirectional conduction unit, such that a total voltage is stored therein. When the electronic apparatus is power off, a user operates the automatically recovering switch to be conducted, such that the state energy storage unit is charged by the total energy storage through the automatically recovering switch, and a storage voltage signal is stored therein. When the electronic apparatus is power on again, the reading unit receives the power, reads out the storage voltage signal, and outputs a read voltage signal accordingly.

A power saving device for a GPS device is to utilize acceleration of gravity sensor to continue detecting the acceleration variation of the GPS device; if an acceleration value is larger than a threshold value, a GPS signal receiver is then started; if the acceleration value is smaller than the threshold value, the GPS signal receiver is then shut. This allows the GPS device to be power saving and not need to facilitate an extra oscillation switch therein to save the production cost.

A detection device and method commonly used for a video interface outlet and earphone line outlet is used to allow the detection device to detect whether a three- or four-terminals plug is inserted in the outlet. The detection device detects whether the impedance value of the video output terminal of the plug is larger than the preset value. If yes, the detection device control a video signal output terminal to output a video signal. If the impedance is not larger than the preset value, the detection device then controls the video signal output not to output a video signal and only to output an audio signal.

摘要:
An illuminating device comprises a heat sink, at least one light emitting module and a speaker. The heat sink has a first containing space, a second containing space and a first channel being in communication with the first containing space and the second containing space. The light emitting module is arranged in the first containing space and contacted with the heat sink. The speaker comprising a thin film is arranged in the second containing space. When the speaker is in operation, the thin film vibrates so that a first airflow from the second containing space to the first containing space through the first channel is formed. In the above-mentioned illuminating device, the vibration of the thin film of the speaker causes air in the first containing space to flow, and the heat dissipation efficiency of the illuminating device is improved.
