  • Patent number: 11074400
    Abstract: A collaborative content management system is disclosed herein for receiving a command to add an annotation object following a character input into a line of a collaborative content item. The system inserts an annotation object onto the line following the character, detects a selection of the annotation object, and displays a secondary collaborative content item in visual association with the character. The system detects textual content that corresponds to a citation within the secondary collaborative content item, and responsive to detecting the textual content, generates for display a template for inputting fields of a citation. The system receives text entered into one or more of the fields, generates a citation based on the text, and inputs the citation into the secondary collaborative content item.

  • Publication number: 20070084923
    Abstract: A dual mode smart card controller is provided. In one embodiment, a USB and ISO7816 smart card controller is provided that determines the type of card that is inserted into a slot. If the smart card is a USB smart card, the controller is adapted to pass control of the smart card to an external PC host USB hub circuit. If the smart card is an ISO7816 card, then control is handled by the dual mode controller. In another embodiment, the controller includes an embedded USB hub circuit to permit the controller to directly control both USB and ISO7816 smart cards. Exemplary control sequencing includes monitoring a C4 signal line for a preselected time period, or generating an enable signal if a USB smart card is detected.

  • Publication number: 20060214003
    Abstract: The present invention provides a device for connecting a contactless integrated chip card (ICC) to a host computer having a USB host input/output bus interface, comprising a first logic set, a second logic set, and a third logic set. The first logic set detects the presence of an external radio frequency transceiver RF circuitry which communicates with the contactless ICC. The second logic set includes a Chip/smart Card Interface Device (CCID) interface, wherein the CCID interface is enabled when the first logic set positively detects the presence of the RF circuitry. The third logic set converts data received by the CCID interface to a format compatible with the USB host input/output signal interface so as to connect the contactless ICC to the host computer.

  • Publication number: 20050081071
    Abstract: A pre-boot security controller in an electronic device is energized even though a power subsystem does not energize operation of a digital computer in the device. The security controller stores supervisor and user passwords in a non-volatile password memory for comparison with a password entered using a security keypad. While the security controller is in a security operating mode, an output signal from the securing controller indicates the existence of that operating mode. Upon entry of a matching password, the security controller enables the power subsystem to energize operation of the digital computer, disables the output signal that indicates the existence of the security operating mode, and the security controller transitions from the security to an application operating mode. In the application operating mode, the pre-boot security controller preserves data about pressings of the security keypad.
