20120139710 | DIRECT COMMUNICATION IN ANTENNA DEVICES - Provided are a method, system, and device in which non-RF (radio frequency) data signals are transmitted to a non-RF data port connected to an antenna of a device. The non-RF data signals from the non-RF data port are coupled to a data bus using a low frequency coupler of the device. RF signals are blocked from the data bus using the low frequency coupler of the device. In another aspect, RF signals are transmitted to the antenna of the device and are coupled to an RF port using a high frequency coupler of the device. Non-RF data signals are blocked from the RF port using the high frequency coupler. Additional embodiments are described and claimed. | 06-07-2012 |

20140168084 | GESTURE PRE-PROCESSING OF VIDEO STREAM USING A MARKERED REGION - Techniques are disclosed for processing a video stream to reduce platform power by employing a stepped and distributed pipeline process, wherein CPU-intensive processing is selectively performed. The techniques are particularly well-suited for hand-based navigational gesture processing. In one example case, for instance, the techniques are implemented in a computer system wherein initial threshold detection (image disturbance) and optionally user presence (hand image) processing components are proximate to or within the system's camera, and the camera is located in or proximate to the system's primary display. In some cases, image processing and communication of pixel information between various processing stages which lies outside a markered region is suppressed. In some embodiments, the markered region is aligned with, a mouse pad or designated desk area or a user input device such as a keyboard. Pixels evaluated by the system can be limited to a subset of the markered region. | 06-19-2014 |
20140169621 | GESTURE PRE-PROCESSING OF VIDEO STREAM TO REDUCE PLATFORM POWER - Techniques are disclosed for processing a video stream to reduce platform power by employing a stepped and distributed pipeline process, wherein CPU-intensive processing is selectively performed. The techniques are particularly well-suited for efficient hand-based navigational gesture processing of a video stream, in accordance with some embodiments. The stepped and distributed nature of the process allows for a reduction in power needed to transfer image data from a given camera to memory prior to image processing. In one example case, for instance, the techniques are implemented in a user's computer system wherein initial threshold detection (image disturbance) and optionally user presence (hand image) processing components are proximate to or within the system's camera, and the camera is located in or proximate to the system's primary display. The computer system may be any mobile or stationary computing system having a display and camera that are internal and/or external to the system. | 06-19-2014 |
20140193030 | GESTURE PRE-PROCESSING OF VIDEO STREAM WITH HOLD-OFF PERIOD TO REDUCE PLATFORM POWER - Techniques are disclosed for processing a video stream to reduce platform power by employing a stepped and distributed pipeline process, wherein CPU-intensive processing is selectively performed. In one example case, the techniques are implemented in a user's computer system wherein initial threshold detection (image disturbance) and optionally user presence (e.g., hand image) processing components are proximate to or within the system's camera, and the camera is located in or proximate to the system's primary display. The threshold detection and/or target presence stages can be selectively disabled for a hold-off period. The hold-off period may be, for example, in the range of 50 to 1000 mSec and triggered in response to an indication that a user of the system is unlikely to be making navigational gestures or that the system is not ready to process video, thereby conserving power by avoiding processing of video frames free of navigation gestures. | 07-10-2014 |
20140267042 | GESTURE PRE-PROCESSING OF VIDEO STREAM USING SKINTONE DETECTION - Techniques are disclosed for processing a video stream to reduce platform power by employing a stepped and distributed pipeline process, wherein CPU-intensive processing is selectively performed. The techniques are particularly well-suited for hand-based navigational gesture processing. In one example case, for instance, the techniques are implemented in a computer system wherein initial threshold detection (image disturbance) and optionally user presence (hand image) processing components are proximate to or within the system's camera, and the camera is located in or proximate to the system's primary display. In some cases, image processing and communication of pixel information between various processing stages which lies outside a markered region is eliminated. In some embodiments, the markered region is aligned with a mouse pad, desk area, or a user input device (e.g., keyboard). Pixels evaluated by the system can be limited to a subset of markered region. A simplified skintone detection process can be employed. | 09-18-2014 |
20140327630 | METHOD, APPARATUS, AND SYSTEM FOR DISTRIBUTED PRE-PROCESSING OF TOUCH DATA AND DISPLAY REGION CONTROL - In an embodiment, a system includes a peripheral controller to interface with a touch controller and to communicate mapping information to identify primary and secondary regions of a display. The touch controller includes logic to filter touch data when it is for a touch within the secondary region and to communicate the touch data to the peripheral controller when it is for the user touch within the primary region. In an embodiment, display logic may determine when and how to use a display bezel area for displaying content, via a combination of criteria. Decision vectors (such as sensors, device configuration, content type, primary display activity) may enable/disable display areas for rendering, with independent control of each side of the bezel. Content can be rendered based on primary display content, environment, other devices and user preferences. Other embodiments are described and claimed. | 11-06-2014 |
