Abstract: Headgear for a respiratory interface comprising multiple separate sections of material joined to form the headgear and different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear.

Abstract: The invention provides systems and methods for tissue-mounted electronics and photonics. Devices of some embodiments of the invention implement high performance, and optionally flexible, device components having miniaturized formats in device architectures that minimize adverse physical effects to tissue and/or reduce interfacial stresses when mounted on tissue surfaces. In some embodiments, the invention provides complementary tissue mounting strategies providing for mechanically robust and/or long term integration of the present devices, for example, via mounting on tissue surfaces that are not subject to rapid growth or exfoliation processes such as the fingernail, toenail, tooth or earlobe. Devices of the invention are versatile and support a broad range of applications for sensing, actuating and communication including applications for near field communication, for example, for password authentication, electronic transactions and biometric sensing.

Abstract: Electronic devices involving contact structures, and related components, systems and methods associated therewith are described. The contact structures are particularly suitable for use in a variety of light-emitting devices, including LEDs.

Abstract: The invention provides systems and methods for wearable and tissue-mounted electronics for monitoring exposure of a subject or object to electromagnetic radiation, particularly electromagnetic radiation in the visible, ultraviolet and infrared portions of the electromagnetic spectrum. In some embodiments, the devices are purely passive devices where absorption of incident electromagnetic radiation by the device provides at least a portion of the power for the measurement of the radiant exposure or flux of the incident electromagnetic radiation. Devices of the invention may include near field communication components, for example, for enabling readout by an external device, such as a computer or mobile device.

Abstract: Methods and apparatus for associating an entity with at least one search query. Some implementations are directed to methods and apparatus for identifying multiple queries associated with an entity and identifying one or more of the queries as an entity search query that provides desired search results for the entity. Some implementations are directed to methods and apparatus for identifying a particular entity and, in response to identifying the particular entity, identifying an entity search query corresponding to the particular entity.

Abstract: The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.
