Abstract: There is disclosed a waveguide for use in an augmented reality or virtual reality display. The waveguide comprises a plurality of optical structures in a photonic crystal. The plurality of optical structures are arranged in an array to provide at least two diffractive optical elements. Each of the two diffractive optical elements is configured to receive light from an input direction and couple it towards the other diffractive optical element which can then act as an output diffractive optical element, providing outcoupled orders towards a viewer. The plurality of optical structures respectively have a shape, when viewed in the plane of the waveguide, comprising twelve substantially straight sides, six of the sides having respective normal vectors at a first angle, and the other six of the sides having respective normal vectors at a second angle which is different to the first angle.

Abstract: Technologies for monitoring beehives in an apiary includes one or more sensors communicatively coupled to a remote data analysis computing device, which is communicatively coupled to a client computing device. The sensors are configured to monitor beehives and/or the environment of the apiary and transmit the sensed data to the remote data analysis computing device. The remote data analysis computing device is configured to analyze the received sensor data, determine whether to perform an action as a function of a result of the analysis, and perform the function, as applicable. The client computing device is configured to interface with the remote data analysis computing device such that a user of the client computing device can view results of the data analysis and actions, as well as provide input and adjust settings administered by the remote data analysis computing device. A model for assessing beehive strength from an infrared image is also disclosed. Other embodiments are described herein.
