摘要： A mobile robot generally including a first suction module, a second suction module and a hinge assembly pivotably connecting the suction modules together. Each of the suction modules includes a support frame defining a vacuum chamber and a vacuum unit supported on the support frame and communicating with the vacuum chamber. The vacuum unit includes a rotating impeller and an exhaust cowling surrounding the impeller. The impeller has an axis of rotation and is adapted to draw air from the vacuum chamber into the impeller in a direction generally parallel to the impeller axis of rotation and to discharge the drawn air in a direction substantially perpendicular to the impeller axis of rotation. The exhaust cowling is adapted to redirect the discharged air, whereby a thrusting force is applied to the support frame in a direction opposite of the direction of the drawn air from the vacuum chamber.

摘要： A testing apparatus is disclosed that includes a turntable, an upper scissor jack assembly and a lower scissor jack assembly positioned in parallel planes, about a longitudinal axis and affixed to a base. The apparatus is powered by at least three motors with supporting controllers. The lower assembly is affixed to the base mechanically via the turntable which allows the lower assembly to rotate with respect to the upper assembly. There are two loading plates attached to the hinges of each scissor jack. The test specimen is secured by the loading plate. Each scissor jack operates by a screw-gear powered by one of the motors. Upon energizing a stepper motor; the screw-gear positions a scissor jack to apply a tension or compression on the specimen. While subjected to tension or compression, the lower jack assembly can be rotated with respect to the upper assembly for in-plane shear loading.

摘要： A spark plug is manufactured by assembling an insulator body and an outer metal shell using an improved crimping die having a specially configured annular working face. The working face includes a flat, annular leading working surface configured to exert a substantial portion of the die force initially on an annular lip of the metal shell to plastically deform the lip inwardly onto an adjacent annular shoulder of the insulator body and a flat, annular trailing working surface configured to subsequently engage the lip and exert a substantial portion of the die force on the shoulder of the insulator body generally perpendicular to the shoulder to internally seal the insulator body and the metal shell by plastically compressing an annular gasket therebetween. The crimping die improves the distribution of the die force on the metal shell and the insulator body to reducew excessive deformation of the metal shell and to enhance compression of the sealing gasket for improved internal sealing purposes.

摘要： A helmet for protecting the head of a user. The helmet includes an outer shell, an inner shell having padding that contacts the head and a cavity formed between the inner and the outer shells, wherein the cavity is filled with a fluid such as air. The helmet also includes a plurality of resilient strands located in the cavity and affixed between the outer and inner shells, wherein an impact force on the outer shell causes the head to impact the padding with a reaction force that compresses the cavity. Compression of the cavity pushes fluid through the strands to increase fluid friction and alter a velocity of the fluid. This decreases the energy of impact and consequently reduces an amount of force transferred to the head thereby protecting the head from normal and shear force.

摘要： A triaxial testing system of material properties having top and bottom joint assemblies that rotate about and move along a longitudinal axis in response to forces imparted by a testing machine. The joint assemblies are connected together by horizontal and vertical linkage assemblies. The horizontal and vertical linkage assemblies are connected to horizontal and vertical loading and clamping assemblies to thereby transfer in-plane and multi-axial loads from the testing machine and the joint assemblies to a material test specimen. The test specimen is rigidly clamped to the horizontal and vertical clamping assemblies. The bases and ends of the test specimen are shaped for clamping and axial loading. Rigid plates may be disposed over ends of composite test specimens for spatially stabilizing such specimens during testing. The test specimens may include devices to measure and record the axial and shear loads, displacement and strains imparted to the specimens during testing.
