Abstract: Systems, methods, and computer-readable media are described for compact radar systems. In some examples, a compact radar system can include a first set of transmit antennas, a second set of receive antennas, one or more processors, and at least one computer-readable storage medium storing computer-executable instructions which, when executed by the one or more processors, cause the radar system to coordinate digital beam steering of the first set of transmit antennas and the second set of receive antennas, and coordinate digital beam forming with one or more of the second set of receive antennas to detect one or more objects within a distance of the radar system.

Abstract: A conversion circuit device for connecting lithium based batteries to a standard inverter/charger for lead-acid batteries and an Uninterruptible Power Supply (UPS) system for homes and facilities comprising a standard inverter/charger for lead-acid batteries, at least one lithium based battery, and a conversion circuit device connecting the at least one lithium based battery to the standard inverter/charger; the conversion circuit device translating the state of the at least one lithium based battery into signals that correspond to the state of a lead-acid battery.

Abstract: A system and a method are disclosed for displaying menu options. A menu icon is displayed on a touch-sensitive screen. In some embodiments, the menu icon is displayed with a feed from a social networking system. In response to detecting a contact with the menu icon, an animation of a plurality of sub-menu icons emanating from the menu icon is displayed. The sub-menu icons move along different predefined paths to different predefined positions. Each sub-menu icon is associated with an interface to post content to a social networking system. In response to detecting a contact with a sub-menu icon, the interface associated with the sub-menu icon is displayed.

Abstract: The present disclosure generally provides for systems and methods that allow for LEDs to be effectively incorporated into existing lighting fixtures, including chandeliers and sconces. In some exemplary embodiments, the light source itself can include a heat sink disposed within a sleeve, a base disposed at the bottom of the sleeve and conductively coupled with the heat sink, an LED component disposed on the top of the heat sink, and one or more optical distributors associated with either or both of the heat sink and sleeve. For example, there can be both an inner and optical distributor, with at least the outer distributor being removable and replaceable. The present disclosure enables LEDs to perform effectively in lighting fixtures such as chandeliers where such performance was previously not achievable. Additionally, the present disclosure provides for ways to retrofit existing lighting fixtures having incandescent lights with LED modules.

Abstract: Optical and thermal splines are integrated in the external envelope of a non-planar lamp allowing the optical output of discrete light sources such as LEDs to be distributed for uniform output and the achievement of desired light distributions such as omnidirectional output. Integrated thermal splines and perimeter location of light sources allow for improved thermal management without significantly compromised optical performance.

Abstract: Optical and thermal splines are integrated in the external envelope of a non-planar lamp allowing the optical output of discrete light sources such as LEDs to be distributed for uniform output and the achievement of desired light distributions such as omnidirectional output. Opposing orientation of light sources is utilized to create integrated optical and thermal splines for improved thermal and optical performance.

Abstract: In one aspect, the present invention provides light emitting devices, including light fixtures and luminaires. In some embodiments, a light emitting device comprises at least one light source, a lightguide operable to receive light from the at least one light source at a first location on the lightguide, at least one light extraction region optically coupled to the lightguide and a substantially non-scattering region along a portion of the lightguide.

Abstract: An outcoupling optic and omnidirectional lamp are provided which enable an omnidirectional light distribution from a lamp with directional light sources such as light emitting diodes. Specific embodiments include the A-type lamp, A19.

Abstract: To encourage purchases and use, licenses to certain interactive applications and/or content are able to be given as gifts to others as part of a user purchasing a license for herself. In one implementation, each purchase of a license to an application includes the right to give a license to up to a predefined limit of other people. For example, the purchasing user buys a license for herself and the right to name a number of other people to also receive licenses to the same interactive application or content.

Abstract: Designs for collimating optical elements and assemblies are provided which are fabricated by a subtractive process using lasers or other tools to create embedded void spaces that provide reflecting walls for internally reflective optical elements. The designs have advantages in cost, reduced development time, and performance. Light from multiple light sources can be mixed and collimated. Some embodiments provide the ability to integrate a large number of internally reflective optics into a single component and very large components can be made. Embodiments are designed for manufacturing and can be made without molding tooling.
