Abstract: Some embodiments of the current invention relate to finding and identifying a transmitter. In some embodiments, two antennas are separated by an offset, and/or receive a single signal. Optionally, a processor determines a direction to the transmitter of the signal. For example, the determination may be based on a phase difference between the response of the two antennas. Optionally, the device further includes an identification module that may determine an identification associated with the transmitter. For example, the system may be used to find a particular object or person and/or to differentiate between a friend and a foe.

Abstract: A head-mounted display includes a right-eye display area and a left-eye display area. A content rendering module retrieves, from a content source, content that includes two dimensional components of content. Each of the components has associated depth properties that have an associated offset value. The content rendering module generates content for the right-eye display area from the retrieved content by applying, for each component, a horizontal shift to the component in a respective first direction by the offset value associated with the component. The content rendering module generates content for the left-eye display area from the retrieved content by applying, for each component, a horizontal shift to the component in a respective second direction opposite the respective first direction by the offset value associated with the component rendering module. The content rendering module then sends the generated content to the respective right-eye and left-eye display areas.

Abstract: Computerized methods and systems create stereoscopic presentations of digital content. A depth transformation module receives an assigned depth value for each of one or more components in a layout editor. Each of the one or more components has an associated initial spatial position in two dimensions. The depth transformation module determines a corresponding offset value from the assigned depth value for each of the one or more components. For each of the one or more components, the initial spatial position of the component is shifted by the corresponding offset value separately in a first direction and a second direction. A rendering module presents the one or more components shifted in the respective first and second directions.

Abstract: A storage vessel retains a quantity of a compound. The compound has molecules that emit photons in response to stimulation by one or more beams of energy. A beam emitter assembly has a plurality of beam emitters. Each beam emitter selectively and controllably emits directional beams of energy toward the storage vessel. A control and processing subsystem selectively actuates the beam emitters in groups of at least two beam emitters. For each group, the beam emitters in the group emit directional beams of energy that converge at a convergence point in the storage vessel. The converging energy beams induce molecules located at the convergence point to emit photons.
