Abstract: In a self-organizing wireless multihop network, each node device selects operation among short-range (SR) and long-range (LR) communication modes, among which the SR mode uses a higher data rate than the LR mode. Each node device advertises connectivity link availability for neighboring node devices, and selectively initiates a link in response to connectivity availability advertised by at least one neighboring node device. The availability advertising is performed in the SR and the LR communication modes, according to a periodicity that is dynamically-variable in response to prevailing circumstances in the local neighborhood. The link initiation is selectively performed in one of either the SR or the LR communication mode based on selection criteria that include data throughput performance associated with different neighboring node devices with which connectivity is available via a certain communication mode.

Abstract: A lighting fixture can dispose a light source in a recess of a ceiling or another surface while providing at least one of three adjustments that facilitates installation or post-installation setup. The first adjustment can support mounting the fixture to surfaces of differing thicknesses while maintaining the light source at a uniform recess depth. The second possible adjustment can facilitate rotating a visible portion of the fixture, typically an aperture or hole through which light transmits from the light source into a room or some other illuminated space. After the lighting fixture is attached to the ceiling, a user can rotate the aperture for alignment with another fixture or another object. The third possible adjustment can provide an illumination pattern that can be tilted to various angles or oriented in various directions according to user preference or to establish a desired lighting effect.
