| 20080240433 | LIGHTWEIGHT SECURE AUTHENTICATION CHANNEL - A secure authentication channel (SAC) between two nodes in a communication network is created by the nodes themselves using mutual authentication. The network has two nodes, a coordinating entity, two PKI-based SACs, and one non-PKI SAC which is created by the two nodes and is for use by the nodes. The coordinating entity generates a master key which is transmitted to two nodes via a PKI-based SAC established between the coordinating entity and each of the two nodes. One node uses the master key to generate a first random number and the second node uses the key to generate a second random number. The second node also has an encrypted third random number. The network also has a third SAC, which is not solely based on PKI, between the first node and the second node and is created when the two nodes have authenticated each other. The mutual authentication process occurs without the intervention of the coordinating entity. | 10-02-2008 |
| 20090128618 | SYSTEM AND METHOD FOR OBJECT SELECTION IN A HANDHELD IMAGE CAPTURE DEVICE - A system and method for automatically selecting an object from a field of view of a handheld image capture device. The system includes sensors configured to sense features of one or more objects in the field of view and a decision unit configured to automatically select one or more objects from the field of view based on the sensed features using a decision algorithm that is based on a decision structure, wherein the decision structure receives and prioritizes inputs from the sensors. The system may also optionally include an object movement detecting module configured to detect movement of objects, and a manual selection unit configured to provide user priorities; if included, the information from these elements may also be used by the decision unit to automatically select the object or objects. | 05-21-2009 |
| 20090128647 | SYSTEM AND METHOD FOR AUTOMATIC IMAGE CAPTURE IN A HANDHELD CAMERA WITH A MULTIPLE-AXIS ACTUATING MECHANISM - A system and method for automatically and optically capturing an image in a handheld image capture device. The system includes an imager and an actuated mounting mechanism attached to the imager. The imager has one or more degrees of freedom (DOF) and includes at least one of a pan DOF, a tilt DOF, and a rotate DOF. In certain embodiments, the device can auto-center a selected object of interest in the image frame, auto-zoom in on the selected object of interest, and/or auto-rotate the captured image. The method includes providing an imager having a pan degree of freedom (DOF) and a tilt DOF, capturing an image by the imager to produce an image frame, selecting an object of interest from the captured image, and auto-centering the selected object in the image frame using one or both of the pan DOF and the tilt DOF. | 05-21-2009 |
| 20090165080 | GENERIC RIGHTS TOKEN AND DRM-RELATED SERVICE POINTERS IN A COMMON PROTECTED CONTENT FILE - Methods and systems of rendering content on a device having a native digital rights management (DRM) system are described. A device, such as an end-user device capable of executing or playing content, acquires content in a common content format file having standardized locations for specific types of data. A generic digital rights token associated with the content is obtained by utilizing one of the standardized locations in the content format file, where the rights token contains information sufficient to allow retrieval of the rights associated with the content. Utilizing data in another of the standardized locations, it is then determined whether the device is registered in a domain. A license server directory may be accessed utilizing data in another of the standardized locations in the common content format file and a domain identifier, a device identifier, or both are transmitted to the license server directory. A native DRM system trigger is received and, upon activation of the trigger, a native DRM license is acquired, thereby enabling rendering of the content in the common content format file on the device. | 06-25-2009 |
| 20100134641 | IMAGE CAPTURING DEVICE FOR HIGH-RESOLUTION IMAGES AND EXTENDED FIELD-OF-VIEW IMAGES - An image capturing device, such as a digital camera, is able to take photos having a resolution higher than the native resolution capabilities of the device determined by the imager. The device can also take photos having a field-of-view (FOV) that is greater than the normal capabilities of the device. The photos taken have a higher vertical and horizontal FOV (or only an increased horizontal FOV creating a panoramic photo) than the lens of the imager allows natively. The imager of the device may be positioned to point in different directions using an actuator, that is, the actuator can pan and tilt the imager. The imager can also zoom in or out at various levels and has a maximum zoom level. To create either type of photo, an array of cells is used as a tool to capture a series of subimages where the imager is pointed in different directions for each subimage. To create the high-resolution photo, the imager is zoomed into its maximum level and captures each of the subimages based on the array of cells. To create the extended FOV photo, the imager is panned and tilted as much as possible using the actuator and captures each of the subimages based on the array of cells. In both cases the subimages are then stitched together to form a final image. | 06-03-2010 |
| 20100146629 | CONTENT PROTECTION SYSTEM COMPATIBILITY IN HOME NETWORKS - In a first embodiment of the present invention, a method for performing digital rights management (DRM) for a media item in a device in a home network is provided, the method comprising: retrieving a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS); determining if the rights token must be downloaded by examining the metadata regarding the DIS; and downloading the rights token by following the pointer if it is determined that the rights token must be downloaded. | 06-10-2010 |
| 20100156781 | EYE GAZE CONTROL DURING AVATAR-BASED COMMUNICATION - An avatar image on a device display, such as a cell phone or laptop computer, maintains natural and realistic eye contact with a user (a human being) while the user is communicating with the other human being, whose avatar is displayed on the device. Thus, the user and the avatar have natural eye contact during the communication session (e.g., phone call). Modules within the device ensure that the avatar eyes do not maintain a fixed gaze or stare at the user constantly and that the avatar looks away and changes head and eye angles in a natural manner. An imager in the device captures images of the user and tracks the user's eyes. This data is inputted to an avatar display control module on the device which processes the data, factors in randomness variables, and creates control signals that are sent to the avatar image display component on the device. The control signals instruct how the avatar eyes should be positioned. | 06-24-2010 |
| 20100259368 | TEXT ENTRY SYSTEM WITH DEPRESSABLE KEYBOARD ON A DYNAMIC DISPLAY - A display component implements a text entry system for a device, such as a cell phone or other handheld device, has various layers that mimic characteristics of a conventional keyboard. A keyboard is displayed on a dynamic touch screen display. When a key is pressed by a user, the surface area of the key on the display depresses, thereby mimicking a conventional keyboard that would typically be used with a desktop or laptop computer. The display component is comprised of various layers or panels. One layer is a compressible touch sensitive or touch screen layer. Adjacent to this layer is a compressible display layer. Another layer is a deformable or cushion layer for supporting a specific weight, such as the weight of user fingers or hands. Adjacent to the deformable layer is a lower touch sensitive layer which has a coordinate system. A user pressing down on a key on the compressible display component at a specific spot creates a downward deformation at that specific spot, thereby providing a more ergonomic feel to the user when entering text into the device. | 10-14-2010 |
