An extended field-of-view near-to-eye display system provides for AR/MR image viewing over about a 180° FOV. The display system may include a multiplicity of display panels per eye of a user and may include both high- and low-resolution display capabilities. The high-resolution displays may be positioned in front of the user's eyes in their primary visual field while the low-resolution displays may be positioned so as to be seen by the user's peripheral vision. The low-resolution displays provide cueing information to the user out to the limit of visual perception (for each eye), placing encoded light and movement in the periphery of the user's vision for enhanced situational awareness.

A diffractive optic reflex sight (DORS) is provided for aiming devices in which a virtual image, such as a reticle, is produced and appears in the distance of a user's view when looking through the reflex sight. A light source illuminates a diffractive optical element (DOE) that includes a modulation pattern that generates a patterned illuminations corresponding with the virtual image. A reflective image combiner then reflects the patterned illumination so that the virtual image appears in the distance of the viewer's view. The DORS optical design system is mechanically and optically stable for precision aiming across a range of environmental conditions and in different use scenarios or applications including use in rapidly changing temperatures, varying light conditions, and a wide range of user proficiencies. The DORS optical design system is a readily manufacturable aiming and sighting device for a wide range of applications from handguns to astronomical telescopes.

The bowl with attachable grinder for use with a pipe is a mechanical structure. The bowl with attachable grinder for use with a pipe claims the benefit of United States 35 USC 120 from non-provisional application U.S. Ser. No. 16/253,282 filed on Jan. 22, 2019. The prior disclosure comprises a partitioned bowl. A gas phase of a pharmacologically active media generated by the combustion of a smoking material passes through the partitioned bowl. The bowl with attachable grinder for use with a pipe comprises an exterior screw thread and a burr grinder. The exterior screw thread removably attaches the burr grinder to the prism structure of the partitioned bowl. The burr grinder grinds the smoking material in preparation for the combustion of the smoking material within the partitioned bowl. The burr grinder deposits the ground smoking material directly into the prism structure of the partitioned bowl.

Holographic sight

The bowl for a water pipe having multiple partitioned compartments (hereinafter invention) is configured for use with a smoking material consumed through a hookah. The invention contains the smoking material during combustion. The combustion of the smoking material releases the pharmacologically active media in a gas phase. The invention is a partitioned structure. The invention is configured to store a plurality of doses of the smoking material. Each dose is stored in a partition. Each partition displays a scale that measures the dose of the smoking material contained in the partition. The invention comprises a partitioned bowl and a transport structure. The partitioned bowl is the partitioned structure that contains one or more doses of the smoking material. The transport structure forms a fluidic connection between the partitioned bowl and the hookah that transports the gas phase of the pharmacologically active media from the partitioned bowl to the hookah.

A direct enhanced view optic (DEVO) provides a user with enhanced target acquisition information, such as real time ballistic solutions, fused thermal imaging, extended zoom, and automatic target recognition. The direct view optic may include an optical device having a front objective, a rear ocular exit, and a waveguide. The front objective and the rear ocular exit may be separated by the waveguide, and the optical device provides a distant image onto a display. A diffractive based holographic display system is coupled to the optical device, and the holographic display system provides a see-through information overlay on the display.

An optical system for displaying light from a scene includes an active optical component that includes a first plurality of light directing apertures, an optical detector, a processor, a display, and a second plurality of light directing apertures. The first plurality of light directing apertures is positioned to provide an optical input to the optical detector. The optical detector is positioned to receive the optical input and convert the optical input to an electrical signal corresponding to intensity and location data. The processor is connected to receive the data from the optical detector and process the data for the display. The second plurality of light directing apertures is positioned to provide an optical output from the display.

Light-based deciphering and transmission of information from one remote party to another in line-of-sight is disclosed. The system speeds the pace of light-based transmissions, the decoding of transmissions, and improves the accuracy of reception of the transmissions. In certain embodiments, the system sends both visual and infrared light to send different types of information to the recipient or to send information under different conditions. Exemplary embodiments disclosed herein demonstrate three exemplary systems (mechanical, LCD, and LED) that are suitable for combination with the other components of the system as disclosed herein. In certain embodiments, the system is configured to focus on the correct light (when there are other lights in view) sending the code (e.g., Morse code or On-Off Keying) and track it.

A method of fabricating a multi-tone amplitude photomask includes providing a mask substrate. The method includes providing a stepped pattern in at least one layer of material on a surface of the mask substrate. The stepped pattern includes at least two steps and at least three levels. Each level of the stepped pattern provides a different intensity of light when a light source shines light on the stepped pattern.

A method of cleaving off a daughter single crystal substrate from a parent single crystal substrate includes providing a stress-mandrel and the parent a single crystal substrate. The parent single crystal substrate has a major surface and an edge surface that intersects the major surface. The major surface extends along a major surface plane. The stress-mandrel has a stress-mandrel coefficient of thermal expansion that is higher than the parent single crystal coefficient of thermal expansion. The method includes bonding the stress-mandrel to the major surface, and cooling the parent single crystal substrate and the stress-mandrel. The cooling of the parent single crystal substrate bonded to the stress-mandrel provides a thermal stress in the parent single crystal substrate sufficient to cleave the parent single crystal substrate. The cleaving extends substantially along a plane parallel to the plane of the major surface. In one embodiment the cleaved daughter substrate was used to make a photovoltaic cell.

A system for communicating with a projectile in flight toward an intended target includes a barrel-launched projectile and a remote receiver. The barrel-launched projectile includes an ordnance portion, an active communications apparatus and an onboard speed control. The active communications apparatus includes an onboard receiver, an electromagnetic wave reception device, and an active transmitter. The electromagnetic wave reception device includes at least one from the group consisting of an antenna and a photo receptor and is configured to receive an electromagnetic signal. The electromagnetic wave reception device is connected to provide a signal derived from the electromagnetic signal to the onboard receiver to deploy the onboard speed control. The active transmitter is connected and configured for transmitting a signal to the remote receiver during flight and before activation of the speed control. The transmitted signal is directed within a cone angle extending in a direction opposite of the barrel-launched projectile's flight direction. The onboard speed control includes a shaped explosive charge. Deploying the onboard speed control initiates explosion of the shaped explosive charge. The explosion of the shaped explosive charge adjusts velocity of the barrel-launched projectile.
