Abstract: The disclosed inventions include an embodiment of a mechanism, wherein an implementation of spherical power is through the concept of gaussian reduction: ? total = ? 1 + ? 2 - ? 1 ? ? 2 ? t n where Øtotal is the total power applied by the two-lens system, Ø1 and Ø2 are the powers of the respective lenses, t is the thickness of the space between the two lenses and n is the index of refraction of the space between the two lenses. As seen in FIG. 5, this can be done with a two-lens system to generate optical power. Other implementations of the device could provide spherical power by using Gaussian Reduction with two Fresnel lenses.

Abstract: An weapon sight system includes a weapon sight having body with an optical element that is configured to superimpose a reticle that is visible through the optical element.

The light source may include an LED for generating a reticle image on the optical element at a plurality of different brightness conditions. The light source may include an array of LEDs for generating multiple different reticle images on the optical element. The weapon sight includes a Hall effect sensor in electronic communication with the controller to adjust user-selectable settings including reticle brightness or reticle image. The weapon sight system includes a magnetic input device for providing an input to the Hall effect sensor of the weapon sight.

Abstract: A method includes receiving a first data block including an identifier for a component, receiving a second data block including usage data for the component and a link to the first data block, storing the first and second data blocks in a blockchain, and allocating respective usage tokens to each of a plurality of entities based on the usage data.

Abstract: The invention relates to a liquid air energy storage system. The storage system includes a cryocooler, a dewar, and a Sterling engine. The cryocooler cools a tip of a cold head to cryogenic temperatures, the cryocooler further includes a heat sink to reject heat from the cryocooler and a cold head that protrudes into a dewar through a cryocooler cavity, the cold head to condense ambient air to create liquified air in the dewar. The dewar holds the liquified air at low temperatures, the dewar having the cryocooler cavity and a Stirling cavity. The Stirling engine drives an electric generator, the Stirling engine further including a cold finger protruding into the dewar through the Stirling cavity, the cold finger to move the liquified air from the dewar to a Stirling heat sink; the Stirling heat sink to expand the liquified air; and the electric generator to generate output electricity.

Abstract: A system includes a first plurality of blockchain nodes including first network nodes external to a vehicle and second network nodes internal to the vehicle, the first plurality of blockchain nodes maintaining a first distributed blockchain ledger; and a first computing device. The first computing device is programmed to transmit a first request to the first plurality of blockchain nodes requesting access to a vehicle network via a communications access port in the vehicle; demonstrate a first proof of work by responding to a second request from the first plurality of blockchain nodes; and receive, based on a first majority of the first network nodes and the second network nodes in the first plurality of blockchain nodes accepting the first request, first authorization specifying access to the vehicle access via the communications access port.

Abstract: A method of forming a gas burner membrane. The method comprises forming a plurality of holes in a sheet of material. The holes are formed by laser cutting a required pattern of holes in the sheet of material.

Abstract: A system includes a computer including a processor and a memory. The memory stores instructions executable by the processor to store an electronic ledger that specifies an authorized operation for an entity to perform for a vehicle, receive a request, including an entity identifier for an entity making the request, to perform a requested operation, query the electronic ledger to determine that the requested operation is the authorized operation, and actuate the vehicle based on the authorized operation. The electronic ledger is a distributed electronic ledger shared between at least the vehicle and the entity.

Abstract: A process is provided for preparing a low density, fibrous primary lignocellulose biomass, particularly straw for anaerobic digestion at large scale, i.e. >2 MWth, which comprises a step that greatly increasing the density of the straw through size reduction, moisture adjustment and compression ahead of loading and subsequent agitation of the resultant biomass in a pressure vessel through an atmosphere of saturated steam providing heat for thermal-pressure hydrolysis and recovering treated biomass from the vessel. The primary lignocellulose biomass may be prepared in admixture with secondary biomass which may be manure-based.
