Abstract: A display system can include a head-mounted display configured to project light to an eye of a user to display virtual image content at different amounts of divergence and collimation. The display system can include an inward-facing imaging system images the user's eye and processing electronics that are in communication with the inward-facing imaging system and that are configured to obtain an estimate of a center of rotation of the user's eye. The display system may render virtual image content with a render camera positioned at the determined position of the center of rotation of said eye.

Abstract: Methods for sending data between client devices, applications therefore, non-transitory computer media, and devices comprising non-transitory computer media.

Abstract: Reconfigurable security systems, devices, and methods are provided. These can include systems having a configuration device, a reconfigurable lock system, and a reconfigurable key system, where transferable tumbler code carriers, having transferable tumbler codes, may be exchanged in order to provide controlled access to the devices or structures secured by the security system. By way of metaphor, the particular teeth configuration of a manual key may be understood as reflecting a single or fixed tumbler code. In embodiments, such a tumbler code may be exchanged, compared, and stored to allow for selective configuration of keys, mating of keys and locks, and selective access to security systems by a key system configured with a proper tumbler code.

Abstract: A method of altering the level of at least one phytochemical in a harvested plant cell comprising chlorophyll or in harvested plant tissue comprising chlorophyll, the plant cell or tissue being capable of photosynthesis and/or being capable of blue light adsorption by shining blue light onto the surface of the plant cell or tissue, wherein the light intensity of the blue light striking the cell surface or the tissue surface is sufficient to initiate a biochemical process within the cell or tissue thereby altering the level of at least one phytochemical therein.

Abstract: A method for storing fresh produce and comestible derivatives thereof while controlling the total viability count and/or surface pathogen count thereon comprises the step of shining light wavelengths selected from blue light, red light or a combination of red light and blue light onto the surface of the produce.

Abstract: A method of treating malting grain, in which the grian is subjected to a water restriction stress after commencement of germination under normal conditions. The grain is germinated in a grain-germinating environment but before completion of germination is subjected to said water-restriction stress by reducing the amount of water available to the grain within said environment. This is done for at least one time-interval sufficient to modify, as compared with normally-germinated grain, at least one of the following parameters, namely: (i) the amount of soluble sugars in a hot water extract; (ii) the alpha-amylase level; (iii) the degree of root and shoot growth; (iv) the total nitrogen content and the soluble nitrogen ratio; and/or (v) the diastatic power; as determined in the germinated and thus-treated grain. Preferably the water restriction stress is imparted by lowering the relative humiditity of air flowing around the grain within a germination environment to below 95%.
