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.

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.

Systems and methods to generate maps or models of structures are disclosed. Features of the structure to be mapped may be determined for the purposes of generating the map or model based at least in part on images associated with the structure, sensor measurements associated with the structure, and phase data of communications signals that interact with the structure. The mapping or modeling processes may be performed at a mapping server that receives images, sensor data, and/or communications signal phase information from one or more user devices, such as mobile devices. The mapping servers may perform a simultaneous localization and mapping (SLAM) process and may enhance the generated maps using sensor and/or communications phase data to map one or more hidden features of the structure.

A method for managing information includes receiving bits of data, determining phasors for bits at only one frequency of a transmission spectrum, combining the phasors of bits that form a phasor having a spectral energy that lies within a predetermined range, and forming a codeword from the bits of the combined phasors.

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.

An apparatus and method is described herein for reducing noise in a power distribution network for an interface. The power distribution network is characterized. And based on that characterization, worst case patterns for the interface are predicted and avoided. As one example, characterization includes providing a stimulus, such as a step function stimulus, and determining a mathematical function response, such as a step function response. Then, based on the step function response, a resonant frequency for the power distribution network is determined; from which patterns that cause the resonant frequency are identified/predicted. And when identified patterns are detected, they are scrambled or manipulated to avoid causing a worst-case noise scenario in an interface's power distribution network.

A Dynamically Terminated Bus (DTB) comprising a transmission line coupled to a plurality of dynamically configurable components and a bus protocol that only permits a single component to transmit at a time. Each of the dynamically configurable components can be configured as a single unbalanced complementary metal-oxide-semiconductor (CMOS) pull-up driver and a gunning transceiver logic (GTL) on-die, pull-up termination receiver. However, only one dynamically configurable component can be configured as the CMOS pull-up driver at a time. Embodiments of the present invention provide a high speed, DTB for coupling to the components.

Systems and methods to provide distributed wireless communications from a plurality of wireless network devices are disclosed. The plurality of wireless network devices may be configured to provide direction communications with one or more user devices. This may be performed by adjusting one or more radio parameters associated with the plurality of wireless network devices. The plurality of wireless network devices may cooperate with each other to provide network connectivity for the one or more user devices with relatively high fidelity, relatively high bandwidth, and relatively low power consumption. The plurality of wireless network devices may further provide distributed processing capability to perform tasks for user devices that may provide task requests.
