Abstract: A multi-antenna system for harvesting energy and transmitting data includes an energy storing unit, antenna transmission units, and a load unit. Each antenna transmission unit includes an antenna module, a splitting module, an energy generation module, and a data processing module. The splitting module splits a wireless signal received by the antenna module into a first splitting signal and a second splitting signal and transmits the first splitting signal to an energy generation module to convert the first splitting signal into electrical energy stored in an energy storing unit and provided to the data processing module. The energy storing unit provides the electrical energy for the load unit. The data processing module receives one of the second splitting signals, converts it into a control signal, and transmits the control signal to the load unit. The load unit operates according to the control signal.

Abstract: The present invention is a message updating system for an electronic label. The system comprises a message updating device, wherein a controller thereof controls a power-supply transmission unit and a message-update transmission unit to respectively transmit a charging signal and a message-updating to the electronic label for charging the electronic label and updating label information of the electronic label. A detection device picks up the label information to generate label content information, transmits the label content information to the controller to make the controller compare the label content information with update comparison information, and generates an alert message if the label content information is different from the update comparison information. The present can charge the electronic label that is mounted on an article and update label information simultaneously while the article is being transported.

Abstract: A display device installed on the handle of a public transportation vehicle displays advertising information. The display device includes a body and two displays. The body includes a housing. The housing has a first surface, a second surface opposite the first surface, a third surface, and an opening. The housing is provided with a fixed hole penetrating through the first surface and the second surface. The housing is provided with a fixing component therein. The housing is provided with two electronic component-accommodating portions therein. The electronic component-accommodating portions are respectively arranged at two sides of the fixed hole. The third surface and the opening are perpendicular to the first surface and the second surface. The display device can reduce waste of ink and paper due to using advertising papers to advertise.

Abstract: An adjustable electronic tag device for a suitcase or luggage includes an electronic tag provided with a fixing assembly thereon. The fixing assembly fixes the electronic tag to the suitcase. The fixing assembly includes a positioning member including a binding hole and a movable fastener arranged in the binding hole. The positioning member connects with an end of a binder and another of the binder encircles the suitcase and penetrates through the binding hole. The binder has a plurality of bars arranged in rows, and the movable fastener is fastened with at least one of the plurality of bars to fix the binder.

Abstract: A portable router comprises a memory unit, a network sharing port, an operating/processing unit connecting with the two components. The memory unit has an original parameter configuration area and an updated parameter configuration area. An originally-configured network address and a prime DHCP server address range are built in the original parameter configuration area. The network sharing port has an external network connection port and an internal network connection port. The external network connection port implements connection with an external network having an external network address. The internal network connection port implements an internal network. The operating/processing unit retrieves the originally-configured network address and compares it with the external network address. When two addresses are identical, the operating/processing unit generates a new network address different from the external network address and a new DHCP server address range.

Abstract: An Ethernet adaptor comprises a box having an upper and a lower covers, a female connector and a circuit board. The upper cover includes an upper opening having a female press-fit element on the side wall, and two upper positioning ribs in the interior. The lower cover includes a lower opening having two positioning protrusions on a lower edge, and two lower positioning ribs in the interior. The upper opening, lower opening, upper positioning ribs and lower positioning ribs form a through-hole. The female connector is accommodated in the through-hole and includes an L-shape body. The bottom of the L-shape body has positioning notches corresponding to the positioning protrusions. An outward-facing surface of a vertical portion of the L-shape body has two positioning members. An inward-facing surface of the vertical portion extends through the through-hole to the interior of the box to connect with the circuit board inside the box.
