20140215637 | SECURITY ARRANGEMENTS FOR EXTENDED USB PROTOCOL STACK OF A USB HOST SYSTEM - Security arrangements for a universal serial bus (USB) protocol stack of a USB host system are provided. The security arrangements prevent an unauthorized or suspicious USB device from communicating with the host system, detect suspicious activity originating from a device which is already communicating with the host system and may provide notification to a user. | 07-31-2014 |
20140098179 | VIDEO CONFERENCING ENHANCED WITH 3-D PERSPECTIVE CONTROL - In one embodiment, images of a first user in a video conference are captured with one or more physical video cameras. The captured images are processed to form a three-dimensional (3-D) model of the first user. A location on a display screen is determined where an image of each of one or more second users in the video conference is shown. One or more virtual cameras are positioned in 3-D space. Each virtual camera is associated with a respective second user and positioned in 3-D space based on the location on the display screen where the image of the associated second user is shown. A view of the first user from the perspective of each of the one or more virtual cameras is rendered. The rendered view of the first user from the perspective of each virtual camera is shared with the associated second user for the respective virtual camera. | 04-10-2014 |
20140084963 | PASSIVE CAPTURE ADAPTER CIRCUIT FOR SENSING SIGNALS OF A HIGH-SPEED CIRCUIT - A multi-stage passive capture adapter (PCA) circuit is configured to sense and recover digital signals present on a high-speed serial bus for capture and analysis in external test equipment. A first stage of the PCA circuit includes a differentiator that functions as a high impedance probe that contacts the serial bus to capture an original input signal waveform of the high-speed digital signals. The signal waveform is fed to a dual-slope comparator/driver that includes a plurality of high-speed comparators and drivers. The second stage includes a differential receiver/shaper that converts logic levels of differential receiver outputs to input signals that set and reset a signal restorer whose output signals are fed to a driver of a driver/shaper. The output of the driver is then fed to a shaper network configured to substantially match an output signal of driver/shaper to the input signal waveform sensed from the high-speed serial bus. | 03-27-2014 |
20130326541 | ENABLING LEGACY APPLICATIONS TO ACHIEVE END-TO-END COMMUNICATION WITH CORRESPONDING LEGACY DEVICE SERVICES - Embodiments described herein enable legacy applications to achieve end-to-end communication with their corresponding device services in a host computer. To that end, one or more legacy protocol stacks are configured to interface with a component that implements and manages a Device Service Streams (DSS) application programming interface (API) which communicates through a Mobile Broadband class driver to a Device Service residing in a Mobile Broadband Interface Model (MBIM) compliant device attached to the computer. In one or more embodiments, end-to-end communication is illustratively achieved through the use of a plurality of components: a Device Services Composite Driver (DSCD), a Device Services Legacy Software Protocol Driver (DSLSPD), and a Device Services Legacy Software Protocol Controller (DSLSPC). | 12-05-2013 |
20130191564 | METHOD FOR DISPLAYING DYNAMIC CONTENTS THROUGH USB STORAGE MEDIA - A presentation system includes a remote device with a dynamic storage subsystem that dynamically updates designated storage locations in actual or virtual memory with content for presentation at times associated with the presentation of the updated content by a presentation device. The presentation device, which is connected to the remote device by a data transport connection, accesses the content from the designated storage locations and presents the content as playback data. | 07-25-2013 |
20130138860 | USB CLASS PROTOCOL MODULES - A computer system includes USB class protocol-aware modules for USB devices as part of a xHCI host controller. The protocol-aware modules serve as accelerators by implementing critical portions of the device class protocols, which includes fetching higher level protocol data directly from client buffers for transmission and delivering decoded data to client buffers on receipt; and emulating a register-based interface for the benefit of system software on the host computer. | 05-30-2013 |
20130014221 | SECURITY ARRANGEMENTS FOR EXTENDED USB PROTOCOL STACK OF A USB HOST SYSTEM - Security arrangements for a universal serial bus (USB) protocol stack of a USB host system are provided. The security arrangements prevent an unauthorized or suspicious USB device from communicating with the host system, detect suspicious activity originating from a device which is already communicating with the host system and may provide notification to a user. | 01-10-2013 |
