Laser-enhanced visual simultaneous localization and mapping (SLAM) is disclosed. A laser line is generated, the laser line being incident on an object and/or environment. While the laser line is incident on the object, one or more images of the object with the laser line incident on the object are captured. The camera is localized based on one or more characteristics of the laser line incident on the object. In some examples, improved feature localization provided by the laser line provides more accurate camera localization, which, in turn, improves the accuracy of the stitched mesh of the object/environment. As such, the examples of the disclosure provide for improved camera localization and improved three-dimensional mapping.

The invention provides a ceramic composite material forming method and a ceramic composite material, and relates to the technical field of ceramic composite material forming. According to the forming method, fiber is soaked into a sizing agent in advance, weaving is directly performed with the sizing agent, the sizing agent is continuously pouring into gaps formed between fiber during weaving, a prefab formed by weaving does not need soaking, and drying and sintering are directly performed, so that the ceramic composite material can be obtained. The forming method cancels a required process of repeatedly soaking the prefab in the traditional forming technology, greatly reduces the workload, shortens the production period, further reduces the operation cost, and improves the defects of complex forming technology, high cost and long production period in the traditional forming technology; the ceramic composite material prepared through the forming method can easily meet the required density. The invention further provides a ceramic composite material. The ceramic composite material has good density.

A plurality of past cross-sectional images are reconstructed from a plurality of past tomosynthesis images obtained by radiographing a subject by tomosynthesis. A plurality of current cross-sectional images are reconstructed from a plurality of current tomosynthesis images obtained by radiographing the subject by tomosynthesis. Each of the plurality of past cross-sectional images is superimposed on a corresponding current cross-sectional image included in the plurality of current cross-sectional images for each cross-sectional plane so as to align structural elements therein. When the structural elements are aligned, a subtraction image between the corresponding past cross-sectional image and current cross-sectional image is produced.

In a film substrate (FB) including a film base material (1) and conductor wiring (23) that is formed on the film base material (1), the conductor wiring (23) is arranged such that the conductor wiring thickness of an external connection portion on the film substrate to which another panel or substrate is connected is thicker than the conductor wiring thickness of conductor wiring portions (bent portions) (25) at other positions.

An improved process for the preparation of acyl aromatic ethers useful as important intermediates for drugs and pharmaceuticals by reacting an aromatic ether with an acylating agent selected from a C2-C8 acid anhydrides, employing nano- and microcrystalline zeolite beta as catalyst is disclosed.

A lacrosse head including a sidewall having upper and lower rails and an optional cross member. At least one of the upper and lower rails and cross member are cored out to define a recess. The recess can be partitioned by multiple trusses into multiple individual voids. The voids can be of increasing depth, progressing from shallower to deeper depths from the bottom rail to the upper rail. The lower rail can be reinforced with additional trusses near the base or ball stop of the head to add strength and rigidity there. The density of the trusses and/or cross sectional area of material can be altered in the upper rail, lower rail and cross member to selectively alter stiffness in those components. The stiffness of these components can also vary to provide different position heads, for example, attack, midfield and defense heads, with selectively different stiffness and strength characteristics.

Silicon nano-crystals may be formed using a heat treatment.

A method for controlling an amount of dampening solution in a printing unit of a printing press using a computer and a measuring device, includes setting an amount of dampening solution in the printing unit based on data of a current print job, reducing the amount of dampening solution towards a smearing threshold with the computer, recording color measurement values with the measuring device in at least one full tone area with low area coverage and in at least one halftone area with high area coverage on a printing material of the current print job, and stopping the reduction of the amount of dampening solution with the computer when a dot gain of the halftone in areas with high area coverage increases significantly and a density of the full tone in areas with low area coverage increases significantly.

A control-cage that can concentrate the distribution of shot-blasting media, a centrifugal shot-blasting device using this control-cage, and a centrifugal shot-blasting device for throwing abrasive grains, are provided.

This control-cage is used for a centrifugal shot-blasting device that rotates an impeller having a plurality of blades at high speed, and that throws shot-blasting media at an object to be processed through the opening of the control-cage by means of the blades. The control-cage is cylindrically shaped and is placed inside the impeller. The opening of the control-cage is made by cutting out the cylindrical part of it in parallel with its central axis. Also, the opening has a quadrangular shape, and has lateral walls located upstream and downstream of the direction of the rotation of the impeller. The upstream wall is made so that the angle between a plane containing the axis and the plane containing both the axis and the inner edge of the upstream wall is larger than the angle between the plane containing the axis and the plane containing both the axis and the outer edge of the upstream wall when they are measured in the direction opposite to the direction of the rotation of the impeller.
