Abstract: A digital manufacturing system for producing first and second objects comprises a platen, a gantry, a pantograph extrusion head system and first and second sets of extruders. The platen defines a workspace upon which the objects are produced. The gantry defines a headspace displaced from the workspace. The extrusion head system is mounted to the gantry for movement in the headspace. The sets of extruders are connected to the extrusion head system and are configured to deposit extrusion material on the workspace to build the objects. Each set of extruders comprises a first extruder mounted to the extrusion head system; a second extruder mounted to the extrusion head system so as to be actuatable from a first to a second position; and a flexible linkage connecting the extruders. The flexible linkages position the second extruders in approximately equal known spatial relationships to the first extruders in the second positions.

Abstract: Systems and methods correct multiplied errors generated by feedback taps in self-synchronous descramblers. The multiplication of errors degrades the performance of most linear cyclic error check codes. Disclosed techniques are general applicable to multiplied errors even when those errors are not confined to a single block. Disclosed techniques permit a reduction in the amount of forward error correction used. For example, in general, to correct t errors, a linear cyclic error correction code requires a Hamming distance of at least 1+(2t)[wt(s(x))]. Embodiments of the invention allow correcting the multiplied errors with a Hamming distance of only 1+(t)(1+wt(s(x))) over the block size n, wherein wt(s(x)) is the weight of the scrambler polynomial s(x).

Abstract: This invention is a system, an apparatus and a method for measuring biomechanical properties of cornea and the intraocular pressure in vivo. More than one dimensional topographic information of the cornea is recorded and analyzed before and during the fluid discharge and converted to the stress-strain relationship and other cornea parameters, for example the cornea thickness and radius of curvature, etc. The deformation of cornea is initiated by a non-contact fluid discharge whose profile is predetermined and monitored in real time. Utilizing this non-contact topographer, the true intraocular pressure can be derived from the response of the cornea due to the impact of fluid discharge and the corneal topographic parameters. One embodiment of this invention includes the use of a multiple color strobe light/multiple detector system to record the corneal topographic deformation due to the impact of fluid discharge.
