Abstract:
Techniques are disclosed for direct viewer projection, which involves having each pixel's emitted light aimed at or otherwise provided directly to the target pupil of a viewing person. In one embodiment, the techniques are implemented using steerable, collimated light sources fashioned into an array to effectively provide a display screen. Each steerable, collimated light source of the array corresponds to one pixel of a given image at a given viewing location, such that no one light source shows a whole image; rather, the whole array is used to display an image. The array can be scanned to provide different images to different viewing locations. The content projected to the different locations may be related (e.g., a movie) or unrelated (e.g., two different movies). A specific viewer can be identified and tracked such that the content is only projected to the target viewer's eyes and no one else's.
Abstract:
A method of adjusting a circuit operating characteristic. The method includes generating a first signal for application to a reference termination. The method then includes generating a first voltage based on the first signal at a first point on the reference termination and generating a second voltage based on the first signal at a second point on the reference termination. The method also includes adjusting an operating characteristic based upon the first voltage and the second voltage. In an embodiment, the operating characteristic can be an impedance.

Generally, this disclosure provides systems, devices, methods and computer readable media for the use of digital TV (DTV) bandwidth for web cache pre-loading. A system may include a receiver module configured to receive a digital television (DTV) signal. The system may also include a data extraction module configured to extract the web cache data from the DTV signal, wherein the web cache data is encoded within the spectral bandwidth of the DTV signal. The system may further include a network interface configured to transmit the extracted web cache data to a device that includes a web cache pre-loading service.
Abstract:
Technologies for monitoring contact between one or more electrodes of a biofeedback monitoring device and a user include an electrode contact analysis device. The electrode contact analysis device is configured to transmit a body coupled communication (BCC) reference signal via a transmission electrode and receive biofeedback signals received by an electrode of the biofeedback monitoring device. The electrode contact analysis device is configured to process the received biofeedback signals to produce a received BCC reference signal from the received biofeedback signals and determine a quality of a contact between the electrode and the user based on the received BCC reference signal.
