Abstract: A lock-detection circuit detects whether a first clock signal is frequency locked to a second clock signal. A lock-detection scheme that continuously evaluates the lock condition between the clock signals and as programmable frequency-offset tolerances for reporting lock acquisition and loss. A quadrature clock generator produces two periodic signals from the first clock signal. The periodic signals are in quadrature, which is to say they are misaligned with one another by ninety degrees. These quadrature signals are sampled on edges of the second clock signal to produce a sequence of states that exhibit a Gray-code progression if first and second clock signals are locked. Errors in the Gray-code progression indicate whether edges of the first clock signal are early or late with respect to the second clock signal. The lock-detection circuit is adjustable to indicate loss of lock under in dependence upon the temporal spacing of errors.

Abstract: An integrated circuit comprises a signal transmitter and a sampling circuit coupled to the signal transmitter, wherein the sampling circuit is to sample output voltage levels of an output of the signal transmitter at different respective times. The integrated circuit further comprises a measurement circuit coupled to the sampling circuit, wherein the measurement circuit is to compare the output voltage levels of the output of the signal transmitter to corresponding reference voltages to identify a first time when a first output voltage level equals a first reference voltage and a second time when a second output voltage level equals a second reference voltage. A time difference between the first time and the second time is used to configure a slew rate adjustment control of the signal transmitter.

Abstract: A computer implemented method and apparatus for just-in-time transcoding. The method comprises receiving at a media server, video content, wherein the video content comprises a plurality of key frames and delta frames; generating, in response to receiving the video content, metadata, wherein the metadata is a lookup table of the plurality of key frames; storing the video content and the metadata; receiving a first request to view video content; generating a playlist for the video content; receiving a second request to view a video segment of the video content; and transcoding the video segment; and transmitting the transcoded video segment.

Abstract: An adhesive material, or “getter,” is applied to one or more interior surfaces of a display module of a near-eye display (NED) device, to act as a trap for foreign particles or debris. The display module can include a frame, a housing, and one or more display elements each to generate an image to be conveyed to an eye of a user of the NED device. The frame can have at least one surface adjacent to the image-generation surface of each display element. The display module can include an exposed layer of adhesive material covering at least a portion of each said surface within the housing.

Abstract: In one embodiment, a method includes receiving a request to refresh a display for a refresh period, wherein the display is coupled to a touch sensor operable to detect touch input at the display. During a first phase of the refresh period, a first portion of the display is refreshed while the touch sensor a second portion and a third portion of the display is activated. The second portion and the third portion are a half screen distance apart. During a second phase of the refresh period, the second portion of the display is refreshed while the touch sensor at a fourth portion and a fifth portion of the display is activated. The fourth portion and the fifth portion are a half screen distance apart.

Abstract: A system and method are disclosed for combining interactive gaming aspects into a linear story. A user may interact with the linear story via a NUI system to alter the story and the images that are presented to the user. In an example, a user may alter the story by performing a predefined exploration gesture. This gesture brings the user into the 3-D world of the displayed image. In particular, the image displayed on the screen changes to create the impression that a user is stepping into the 3-D virtual world to allow a user to examine virtual objects from different perspectives or to peer around virtual objects.

Abstract: Embodiments of the present invention relate to extraction of a social graph from contact information across a confined user base. Users are typically subscribed to a service that backs up data from end-user devices to a cloud. The data includes contacts from mobile address books. The service is able to determine relationships of contacts in the cloud to build a social graph or map of these contacts. The social graph can be used to drive individual and group analytics to, for example, increase membership and provide value-added features to its service members.

Abstract: A system and method are disclosed living room movie creation. Movies can be directed, captured, and edited using a system that includes a depth camera. A virtual movie set can be created by using ordinary objects in the living room as virtual props. The system is able to capture motions of actors using the depth camera and to generate a movie based thereon. Therefore, there is no need for the actors to wear any special markers to detect their motion. A director may view scenes from the perspective of a “virtual camera” and record those scenes for later editing.
