Abstract: The present disclosure provides a wireless communication system including a first host computer, a communication dongle, a second host computer and an input device. The communication dongle is connected to the first host computer via a USB interface, connected to the second host computer via a Bluetooth interface, and connected to the input device via a wireless interface. The first host computer has first application software for intercepting the operating signal(s) of the input device and transferring, via the communication dongle, to the second host computer to be executed thereby. The first application software also controls the first host computer to ignore the operating signal(s) during the operating signal(s) is being transferred to the second host computer.

Abstract: A semiconductor structure includes a conductive line, a pad layer, and a barrier layer. The conductive line is embedded in a multi-level interconnect structure. The pad layer is over the conductive line. The barrier layer is between the conductive line and the pad layer. The pad layer is electrically connected to the conductive line through the barrier layer, and the barrier layer includes a first poly-crystalline layer and a second poly-crystalline layer. A boundary is between the first poly-crystalline layer and the second poly-crystalline layer.

Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.

Abstract: A self-moving cleaning device includes: a base; a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface; a vacuum module arranged over the base; a dust box arranged over the base and connected to the vacuum module, the dust box including a first opening and a second opening; a first suction port arranged on the base and including a first suction inlet connected to the first opening; a second suction port arranged on the base and including a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port; a roller brush device arranged on the base and within the second suction port; and an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening.

Abstract: A self-propelled cleaning machine includes a base, a walking module, a lift module, a cleaning device and a reciprocating device. The lift module includes a lift seat, which is provided below the base and is configured to move up and down relative to the base for the lift seat to approach or depart from the base. The reciprocating device is connected to the cleaning device. At least a portion of the reciprocating device is configured to be connected to the lift seat of the lift module, so that the at least a portion of the reciprocating device moves up and down along with up-and-down movements of the lift seat. Moreover, the reciprocating device is configured to enable the cleaning device to perform a reciprocating motion relative to the lift seat in a mopping mode to thereby mop the floor back and forth.

Abstract: A display device includes a display panel, a first substrate, a first pressure electrode layer, a second pressure electrode layer and a compression layer. The display panel has a display area and a peripheral area located besides the display area. The first substrate is disposed opposite to the display panel. The first pressure electrode layer is disposed at one side of the first substrate facing the display panel and corresponding to the peripheral area. The second pressure electrode layer is disposed at one side of the display panel facing the first substrate. The compression layer is disposed between the first pressure electrode layer and the second pressure electrode layer.

Abstract: A method for an Open Mobile Alliance (OMA) multimedia exchange allows a sender to send a multimedia data to a receiver via a rights issuer. The method begins by registering to the rights issuer and sending a pubic key from the sender to the rights issuer. Next, a right object and a content object are sent from the sender to the rights issuer, wherein the right object records a content key encrypted by a private key of the sender. Then, the public key is used by the rights issuer to decrypt the content key, and the right object and the content object are packaged into a DRM content format (DCF) object. Finally, an OMA download is used over the Air (OMA download OTA) to send the DCF object from the rights issuer to the receiver.

Abstract: A cipher method and system for multicast service. A group includes multiple user equipment, each having a respective key. The keys are orthogonal to one another. A content provider provides a raw message to the user equipment of the group. A BM-SC server has a key set composed of the respective keys of all user equipment of the group to encipher the raw message to thus obtain an enciphered message for broadcast. All user equipment of the group receives and deciphers the enciphered message with the respective keys. When a user equipment leaves the group, the key set held by BM-SC is updated by removing the key of the leaving user equipment.
