An optical system for eye tracking is disclosed. The system includes a light guiding prism that guides light from an ocular object to an imaging system through multiple internal reflections. The light guiding prism may include one or more freeform surfaces having optical power.

An insole assembly for use in footwear is provided. The insole assembly generally includes a full-length insole base made of a flexible and resilient material (e.g., resiliently compressible foam), and a heel cap made of a generally rigid material (e.g., a carbon fiber reinforced polymer) which is attached to the insole base and mimics the contours thereof to provide proper biomechanical support of the heel and arch areas of a foot in a particularly lightweight and sleek form factor.

The invention relates to the field of building construction machines, in particular to a four-beam steel structure tower crane foundation provided with counterweights and capable of being folded and moving quickly. The four-beam steel structure tower crane foundation mainly comprises main beams (1), a cross-shaped supporting frame (4), the main counterweights (2), the main beam counterweights (3)and ground anchors (1101) and is characterized in that the four steel structure main beams (1) and the adjacent main beams are matched through lug plates (15) with holes and hinged through pin shafts(16), wherein the lug plates (15) with the holes are arranged on the two sides of the front ends of the four steel structure main beams (1); the four steel structure main beams are distributed in a cross shape; the cross-shaped supporting frame (4) is arranged among the four main beams and connected with front blocks (14) of the four main beams through bolts (7) correspondingly, and a set of correction sizing blocks (5) is arranged between the cross-shaped supporting frame (4) and the front block (14) of each of the four main beams; and each main counterweight (2) is arranged between the two corresponding adjacent main beams and pressed on rib plates (17 and 18) at the bottoms of the main beams, and the main beam counterweights (3) are arranged in a main beam box body structure. The four-beam steel structure tower crane foundation is stable in structure, simple in manufacturing process, convenient and fast to move and transport and high in repetition utilization rate, compared with anexisting tower crane foundation, resource waste is reduced, the cost is saved, and the environment is protected.

A communication system, including a mobile communicator including a modem for conducting a communication with a remote party, an input unit for inputting communication data to the modem, and an output for outputting communication data from the modem, a display device including an input unit, an output unit, a connector for engaging the mobile communicator and for exchanging data with the mobile communicator, and a display for displaying party-specific information about the remote party involved in the communication, wherein the modem switches to receive its communication input via the display device input unit and directs its communication output to the display output unit when the mobile communicator is engaged with the connector, and wherein the modem switches back to receive its communication input via the mobile communicator input unit and directs its communication output to the mobile communicator output unit when the mobile communicator is disengaged from the connector.

A catcher tank assembly is provided for a waterjet cutting machine. The catcher tank assembly includes a catcher tank having a plurality of tank sections detachably coupleable together in a side-by-side manner to collectively define a catcher tank having a desired configuration. The catcher tank assembly further includes a workpiece support system detachably coupleable to an interior cavity of the catcher tank. The workpiece support system may include a plurality of workpiece support modules arrangeable in an array to support a workpiece platform of the waterjet cutting machine. The workpiece platform may be formed, for example, by a series of slats supported transversely to parallel rows of the workpiece support modules. Methods and systems which relate to or include the aforementioned catcher tank assembly are also provided.

The invention relates to a sample rod for automatic rotating ultrasonic detection of rods, which comprises a cylindrical rod body, a blind hole is opened at the upper end of one side of the rod body, and a central Horizontal hole, on the rear side of the central horizontal hole, there is a surface short shallow groove on the upper surface of the rod body, and on the rear side of the surface short shallow groove, there is a subcutaneous horizontal hole also located on the upper surface of the rod body, the rear side of the subcutaneous horizontal hole There is a surface long and deep groove on the upper surface, a central horizontal hole in the middle of the rod body is provided on the rear side of the surface long and deep groove, and a near-surface horizontal hole in the lower part of the rod is provided at the rear end of the central horizontal hole. There is a central horizontal hole in the middle of the rod near the rear end of the rod; it has standard shape, reasonable layout of artificial injuries, clear marking, simple structure, comprehensive functions, easy operation, accurate calibration, safety and practicality, and requires no maintenance. Features.

The invention discloses a production method for reducing the occurrence rate of folding at the edge of a wide plate, and relates to the technical field of steel material forming and control. After the pouring section, carry out secondary chamfering, the secondary chamfering pressure is set to 70~80bar, and the secondary chamfering size is 13~15mm; Phosphorus removal operation is not carried out, and phosphorus removal operation is carried out after forming pass and widening, and finishing rolling pass; the width ratio is greater than 1.5 times, the trimming amount of the rolled steel plate is ≥80mm, and the width ratio of all steel grades is ≤2.0 times; the strength level of steel grades If it is greater than 500MPa, the width ratio should be set to be ≤1.8 times, and if the width ratio is greater than 1.5 times, the trimming amount of the rolled steel plate should be greater than or equal to 100mm. The invention solves the manufacturing defect of the edge folding of the extra-wide steel plate in the production process.

The invention relates to a heat-preservation pipe shell and a mounting method thereof. The heat-preservation pipe shell structurally comprises a bottom layer heat-preservation structure, a middle layer heat-preservation structure and an outer layer heat-preservation structure in sequence from inside to outside; reinforcing base material structures are arranged on the inner surface and the outer surface of each layer of heat-preservation structures for fixing heat-preservation layers; and concave-convex modules are arranged at the two ends of each layer of heat-preservation structures, thus thetwo heat-preservation pipe shells can be mutually buckled tightly, and the heat-preservation effect is good. A sliding device and a rolling body are arranged between the two ends of the bottom layerheat-preservation structure and a high-temperature pipeline, the overall heat-preservation pipe shell can be supported to slide on the high-temperature pipeline, the heat-preservation pipe shell can be precast in advance, on-site construction, mounting and dismounting are quick and safe, and the labor intensity, the construction risk and the maintenance cost of on-site construction can be reduced;and a thin air layer is arranged among the bottom layer heat-preservation structure of the heat-preservation pipe shell, the high-temperature pipeline and the sliding device, thus the energy saving effect is greatly improved, the problem that the heat-preservation layer is excessively thick is solved, and the heat-preservation cost can be lowered reasonably.
