Abstract: A battery powered system and a battery powered method are provided. The battery powered method includes: disposing a first power connector and a first magnet on a first connecting face of a first electronic device; and disposing a second power connector and a second magnet on a second connecting face of a first battery device, wherein the first power connector is connected to the second power connector in response to the first magnet and the second magnet being attached to each other, and the first battery device powers the first electronic device via the first power connector.

Abstract: A control system and a control method are provided. The method includes: controlling, by a primary host, a plurality of clients actively; coupling a secondary host to the primary host through a synchronization link and a transmission link different from the synchronization link, where the plurality of client are coupled to each other in series on the transmission link; transmitting, by the primary host, a first instruction to the transmission link, and transmitting a first synchronization signal corresponding to the first instruction to the secondary host through the synchronization link; and determining, by the secondary host according to the first instruction and the first synchronization signal, that a failure occurs on at least one of the synchronization link and the transmission link.

Abstract: A picking system comprises a radio frequency identification (RFID) tag, a case, a two-wire conductive strip, at least one identifying unit and a processing unit. The two-wire conductive strip is electrically connected between the identifying unit and the processing unit. The identifying unit reads tag information within the RFID tag for actively and instantly controlling the authorization of an operating staff assigned for particular items thereby improving the accuracy of picking items.

Abstract: An electronic display comprises a transversally U-shaped fixing beam with a two-wired conducting strip installed therein. Two terminal-fixing bases to fix the two-wired conducting strip and connected electric cables are provided at both ends of the two-wired conducting strip, respectively. Two magnetic connectors are disposed at the back side of each display corresponding to the two-wired conducting strip, when the display is disposed on the fixing beam the electric connection is achieved through magnetically adhesive contact of the magnetic connectors with the two-wired conducting strip. The invention has the advantage of simple installation and flexible positioning.

Abstract: The present invention provides a transmission interface conversion device, which can first convert the communication signal of a master equipment controller and then connect to a plurality of slave devices through a pair of transmission lines so as to perform data transmission and power supply synchronously. The transmission interface conversion device includes: a conversion interface, formed by at least one repeater circuit, which transmits data by half-duplex; a signal inspector, which inspects whether a signal has been transmitted to the conversion interface; a control unit, to determine the orientation and the operation method of the repeater circuit by using the signal that has been inspected by the signal inspector; and a voltage adjustor, to supply needed electric power to all the above-mentioned circuits. The invention has features of being installed and maintained easily as well as being able to reduce the cost of cabling.

Abstract: An universal multimedia book interfacing device is disclosed in this invention. This device is used for operation with a multimedia book. The interfacing device includes a first adapting connector provided with connection compatibility for electrically connecting to several different multimedia books. Each multimedia book is provided with user interfaces for accepting user input signals therein and delivering user output signals therefrom. The universal interfacing device further includes a second adapting device provided with connection compatibility for electrically connecting to a data storage containing data relating to the multimedia books. The universal interfacing device is provided for electrically transmitting the user input signals received from one of the multimedia books to pre-designated locations in the data storage for generating user output signals and for electrically transmitting the user output signals to the multimedia books.
