International Classification:
B01J 19/00
US Classification:
422242, 422129
Abstract:
A reaction hydrogen production control mechanism is provided that includes, a solid sodium borohydride mixture, a liquid fuel reactant, at least one liquid delivery medium (LDM), a movable boundary interface (MBI) and a reaction zone, where the MBI is disposed to provide a constant contact between a reacting surface of the solid fuel mixture and the primary LDM to form the reaction zone. A reaction in the reaction zone includes a hydrolysis reaction. The MBI moves according to a spring, gas pressure, or an elastic membrane. Product paths are disposed to transfer reactants from the system. The product paths can include a channel on a surface of the solid fuel mixture, a channel disposed through the solid fuel mixture, a channel disposed about the solid fuel mixture, a contained region disposed about the solid fuel mixture, or a conduit abutting the solid fuel mixture.

G02B 27/01
G02B 26/08
Abstract:
Head-worn computers may include a rigid optical chassis mechanically configured to provide a stable optical mounting reference plane with an image source reference plane, a first image source mounted on the image source reference plane and configured to project a first image light from the stable optical mounting reference plane to a combiner positioned in front of a user's eye when the head-worn computer is worn by the user, an outer frame configured to hold the optical chassis such that, when worn by the user, the first image light is aligned with the eye of the user, and an arm rotatably mounted on the outer frame and adapted to be positioned on a user's ear, wherein the arm comprises a battery compartment and a wire connected to at least the first image source.
