In some embodiments, eye tracking is used on an AR or VR display system to determine if a user of the display system is blinking or otherwise cannot see. In response, current drain or power usage of a display associated with the display system may be reduced, for example, by dimming or turning off a light source associated with the display, or by configuring a graphics driver to skip a designated number of frames or reduce a refresh rate for a designated period of time.

A 360 degree panorama can capture a view of a real world environment. The view can be a 360 panorama which can conform to a stereographic projection. The capturing can be performed by a one shot panoramic video capture device lacking a display. A 360 degree arc frame can be analyzed to determine a one-to-one mapping to a target projection. The target projection can be a cylindrical or an equirectangular projection. The stereographic projection can be mapped to the target projection in real-time without performing a digital stitching operation within the device. Distortion in the target projection resulting from the mapping can be corrected. The target projection can be conveyed in real-time wirelessly to a display of a communicatively linked computing device.

A transparent metal mesh is used as an antenna element and is disposed over a graphical display so that the graphical display can be seen through the transparent metal mesh. A radio circuit is coupled to the metal mesh to receive radio signals using the transparent metal mesh. In some embodiments the radio circuit can also transmit signals using the transparent metal mesh as an antenna.

A stereographic panoramic media (SPM) can be received. The media can include a 360 degree field of view (FoV) within the horizontal plane and a usable FoV within the vertical plane. A first, second, and third field of view associated with the SPM can be identified. The first FoV can be 180 degree field of view and the second and third FoVs can encompass 90 degree FoV within the horizontal plane. The SPM can be translated to a cylindrical panoramic media (CPM). The CPM can conforms to a three dimensional hollow cylindrical projection (CP). The first FoV of the SPM can be mapped onto the inner surface of the CP, and the first and the second field of view can be mapped onto the outer surface. The CPM can provide a visible continuous field of view of at least 270 degrees.

A calibration method can begin by positioning a calibration image source around and substantially proximate to the exterior surface of a panoramic optical device that utilizes a conical quadric reflector having an aperture in its apex. The calibration image source can be made of a material that is substantially transparent to allow the passage of environmental light and can utilize a predetermined color palette having a calibration feature, such as a geometric shape and/or a line, which is in a known location. A quadric image of the calibration image source can then be captured. Coordinates for a visual image center of the calibration image can be determined by an image center calibration program using the location of the calibration feature. The visual image center can be the point around which a quadric image is transformed into a visually-correct panorama. The determined visual image center coordinates can be stored.

A wearable alert device includes an audio transducer and driver circuit that allows selection of either a high or low volume setting for driving the transducer. The driver circuit is operable in a single ended mode for low volume and a double ended mode for high volume. The single ended mode holds one terminal of the transducer low while the other is driven in correspondence with a clock signal, while the double ended mode drives one terminal in correspondence with the clock signal and the other terminal is inverted from the clock signal. The transducer is activated in response to an alert event, and can be driven according to a profile or pattern.

A host and a communicatively linked paired tag can be identified. The tag can be associated with a tracked entity. The tag can be a low power computing device which can provide a location of a tracked entity to the host. An out of range condition can be detected. The condition can result in communication between the host and the tag being temporarily interrupted. A last location of the tag can be established. A set of hosts proximate to the last location can be determined. The set of hosts can be queried to determine if the hosts have received an advertisement message from the tag. Each of the set of hosts can be linked to a different paired tag. A notification can be conveyed to the host when the set of hosts receives the message from the paired tag. The notification can include a new location of the paired tag.

A portable wireless communication device having a display screen, a light source that is capable of illuminating the display screen, and a processor coupled to the light source, dynamically adjusts a period of time during which the display screen is illuminated. The processor couples power to the light source to illuminate the display screen, determines at least one illumination time parameter associated with information to be displayed on the display screen, and maintains a coupling of power to the light source for a period of time that is based on the at least one illumination time parameter. In other embodiments of the present invention, the processor may further determine to not illuminate the display screen, or to terminate illumination of the display screen prior to expiration of the period of time, based on a received instruction or a detected level of ambient light.
