|Abstract||A recursive hexapod testing machine for mechanical testing of deformable material specimens under six degrees of freedom multiaxial loading. The machine includes a fixed base, a movable base connected to the fixed base at by a hexapod arrangement of six linearly extendable actuator linkages, with an end of each linkages attached to the movable base and the other end of the linkage attached to the fixed base. Each actuator linkage includes a hydraulic cylinder and piston, a digitally-controlled electro-hydraulic servo-valve for actuating the hydraulic cylinder in response to a digital command string, a load cell in line between the piston and the universal joint attached to the movable base, a linear variable displacement transducer for measuring extension of the piston, and a magneto-resistive position transducer for measuring a position of the piston. The servo-valves extend each hydraulic cylinder a predetermined amount to effect a desired motion of the material specimen.|

This patent was granted in 2 years, 227 days, which is a slower than average speed.
It has 16 claims, which is far fewer than average for this category.
Its proximity to basic research is much less than others in this category, and it displays a much slower than average technology cycle time.
This patent received far fewer citations from other patents, and references far fewer other patents, as compared to other patents in this category.
This patent had a slower than average grant time compared to others in this category.
Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.
This patent has far fewer claims compared to others in this category.
The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.
This patent has received far fewer citations from other patents, than others in this category.
Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.
This patent referenced many more citations to other patents, than others in this category.
A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.
This patent has much less proximity to basic research compared to others in this category.
Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
