Abstract: In certain embodiments, item relocation may be facilitated via augmented reality cues and location-based confirmation. In some embodiments, in response to a detection of a first pattern in a live video stream obtained at a client device, a first location associated with the client device may be obtained, and an augmented reality presentation of a visual directional cue may be presented on a user interface of the client device such that the visual directional cue is overlaid on the live video stream. The visual directional cue may include visual directions from the first location to a destination location. In response to an indication that the item has been relocated to the destination location, a determination may be made as to whether the client device is within a threshold distance from the destination location. A confirmation may be generated in response to the client device being within the threshold distance.

Abstract: In certain embodiments, model-based tracking-related prediction for shipped containers may be provided. In some embodiments, scan event information may be obtained. The scan event information may indicate a first-location scan event associated with a first container that occurred at a first location, a first-location scan event associated with a second container that occurred at the first location, and a second-location scan event associated with the first container that occurred at a second location. A prediction model may be used, without a second-location scan event for the second container occurring at the second location, to generate a prediction regarding (i) the second container being at the second location subsequent to being at the first location and (ii) the second container being at a third location subsequent to being at the second location. The prediction may be generated, using the prediction model, based on the scan event information.

Abstract: Disclosed is a glide path indicator (2) comprising a light emitter (20) configured to emit a visible light signal that defines a glide path (14) for use by a pilot of an approaching aircraft (10), and a camera (22) configured to capture images of the approaching aircraft (10), the camera (22) being arranged such that at least part of the glide path (14) defined by the light emitter (20) is located within a field of view of the camera (22). The glide path indicator (2) may be mounted to a vehicle (4), for example, an aircraft carrier. The glide path indicator (2) may further comprise a stabilization module (26) configured to stabilize the light emitter (20) and the camera (22) so as to reduce or eliminate the effects of the vehicle's motion on the glide path (14) and the field of view of the camera (22).

Abstract: A large, deployable space telescope (1) includes an optical system element (4) and a support structure (5) supporting the optical system element. The support structure is formed of a composite material (10) of boron and carbon fibers in a plastic resin matrix. The composite support structure has a net coefficient of thermal expansion within ±0.1 ppm/K at temperatures below 75K which enables diffraction limited performance of the telescope under cryogenic operational temperature variations.

Abstract: An articulating connector installed between a solid axle and a leaf spring suspension in a vehicle, which provides for lateral angular articulation of the axle about an axis parallel to the longitudinal axis of the vehicle without twisting the leaf spring laterally. The result is greater articulation of the axle and elimination of spring binding, thereby providing more freedom of spring travel and a great reduction in interleaf friction in the spring. Shear stresses on the bolts securing the spring eyes to the vehicle chassis or frame are also greatly reduced, thereby greatly increasing the life of these components. The present connector is directed to use in vehicles having either rear or front solid axle systems, or both, suspended by generally longitudinally oriented leaf springs. The present connector may be applied to either overslung or underslung axles, and provides greater freedom of suspension articulation than was achievable in the past with such solid axle and leaf spring suspension systems.

Abstract: A process for artificially producing a relatively high density, vitrified composite novaculite product of relatively homogenous, characteristics with a MOH hardness of between 7.0 and 8.0, and the artificial stone product thereby produced. First a supply of dry abrasive comprising at least 95% by weight silicon dioxide is supplied. This source preferably includes mixtures of 100 mesh novaculite powder and 200 mesh novaculite powder. The dry abrasive mixture is thereafter mixed with a wetting agent, such as a 16:1 mixture of liquid organic concentrate and water, a temporary binder, calcium stearate, and a high refractory frit. The resultant mixture is thoroughly blended to form a first intermediate mixture having a weight of approximately 64% of said dry abrasive, 5.72% of a temporary binder, 3.08% of the wetting agent approximately 1.98% calcium stearate, and approximately 24.3% frit.
