20080228110 | Device for computerized dynamic posturography and a method for balance assessment - A device for balance training and assessing dynamic balance by measuring a subject's ability to react to perturbations. A universal joint assembly is translated at the base of a support plate while a top plate on which the subject stands is fixed against translation. The universal joint permits the attached top plate to rotate about at least one and preferably multiple axes, and the subject must control balance following the translation of the universal joint. All components are housed in a one-piece platform assembly, made up of two plates in which the components are mounted. An existing force plate measurement system is placed on the top plate, and the subject stands thereon during use. A virtual environment, by image-creating devices, may be used to create a realistic sensation of tripping and general postural instability, or shifting of the support surface. | 09-18-2008 |
20110277562 | LOW PROFILE TRANSDUCER WITH HIGH MOMENT CAPACITY - A load transducer for use in an automated control system such as those used in robotic assemblies, and other linkage systems separated by joints. The transducer is capable of measuring force and moments transmitted by the joint of the robotic assembly. This localized sensory data is utilized by a microprocessor to control the motion of the linkages of the system. In addition to being very accurate and reliable, the Load transducer has a low profile and small size. This invention is easily manufactured using strain gage technology. | 11-17-2011 |
