A cover for a tablet PC provides protection to the body while allowing free access to a touch screen and other controls. The cover has an integrally connected keyboard or other input device which can be simply deployed for use, allowing conventional keyboard- or other-based input to the PC. When not in use the input device can be stowed at the rear of the cover, complementing device protection thereto. The cover further provides support elements allowing the PC to be situated for use on a horizontal surface, with the actual angle of situation adjustable to meet individual needs. When not needed or for transport, the support elements collapse and are received within the cover. In addition, the cover allows the PC to be situated, with the input device deployed or otherwise, in either a landscape or portrait orientation.

Located within a GFCI device having a receptacle is a movable contact bearing arm which is held in either a closed or open position with a fixed contact by a latching member that is connected to the spring loaded reset button. The reset button assumes a first or a second position which is determined by the conductive state of the GFCI. When the GFC is in a conducting state, the reset button is substantially fully depressed within the housing of the GFCI. When the GFCI is in a non-conductive state, the reset button projects outward beyond the top surface of the housing of the GCFI. Thus, the movable contact bearing arm, acting through a latching member, determines the position of the reset button. A blocking member located within the body of the GFCI is positioned by the reset button to allow free access of the prongs of a plug into the openings of the receptacle when the reset button is depressed or to block at least one opening of the receptacle to prevent a plug from entering the openings of the receptacle when the reset button projects out beyond the surface of the housing. Thus, when the GFCI is in a conducting state, the reset button is recessed within the GFCI housing and positions the blocking member to the first position to allow the prongs of a plug to be inserted into the receptacle openings. When the GFCI is in a non-conducting state, the reset button protrudes outward from the housing of the GFCI to position the blocking member to the second position to block at least one opening of the receptacle to prevent the prongs of a plug from entering the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a fault state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a fault state and, therefore, can eliminate the need for the bridge contacts.

A system and method of use for Access Files and Transferrable Access Right System for digital intellectual properties (IP). An IP-User gain paid, sponsored or free access of specific level of Access Right to remotely archived digital IP. Using the system's custodial software installed in the IP-User's access device, the IP-User downloads a copy of potentially large digital IP for local access and creates Overlays of value-added information for the digital IP. The Access Right and the Overlay information are stored in a small protected Access File. The large digital IP is deleted after each use, if desired, for security purposes or to save local memory space. The Access Files are stored in local protected folders and optionally stored securely in the remote IP archive system and they are indexed, searchable and retrievable by keywords and partial information. The IP-User opening the Access File will cause the applicable archived digital IP to be Access-Right-verified, accessed and downloaded again, the annotation overlay will be applied and then the composite IP is presented to the IP-User. The IP-User's Access Right is registered and can be securely transferred to another IP-User using the Transferable Access Right System.

The invention discloses an intelligent SD card and a method for accessing the intelligent SD card and solves the problem of incompatibility in drivers of various intelligent SD cards. The intelligent SD card comprises an SD interface, an SD memory, an intelligent card and an SD controller. The method for accessing the intelligent SD card comprises the steps that: an application program writes an interface file of the intelligent card; the SD controller is notified to establish the communication with the intelligent card; the application program reads the interface file and receives response data sent back by the intelligent card; when the communication is successfully established, the application program writes an operating command of the intelligent card in the interface file, which is retransmitted to the intelligent card by the SD controller; and the application program reads the interface file and receives the response data sent back by the intelligent card by the SD controller. The method provided by the invention can realize the drive-free access of the intelligent SD card and any upper layer application program which can access the SD card can conveniently access the intelligent card embedded in the SD card through the interface.

The invention relates to a participant station (10; 30; 50; 60) for a bus system (1; 2) and to a method for improving the error tolerance of a participant station (10; 30; 50; 60) of a bus system (1; 2). The participant station (10; 30; 50; 60) comprises a transmitting / receiving device (13) for transmitting a signal via the bus system (1; 2) to an additional participant station and for receiving a signal via the bus system (1; 2), wherein exclusive, collision-free access of a participant station (10, 20, 30, 50, 60) to a bus control (40) of the bus system (1; 2) is guaranteed at least temporarily, and a modification device (12; 14) for modifying the transmitting properties of a transmitting path (131) of the transmitting / receiving device (13) and / or the receiving properties of a receiving path (132) of the transmitting / receiving device (13).
