Abstract: A drilling assembly for downhole to surface communications is provided. The drilling assembly includes a series of pipe segments coupled in fluid communication between a slip ring assembly and an end pipe portion. The slip ring assembly is coupled in data and fluid communication with the pipe segments. A surface communications link is in data communication with the drilling assembly via the slip ring assembly. An end pipe portion is coupled with the drilling assembly that includes an electronics assembly with electronic components for transferring data to the slip ring assembly via the drilling assembly. A drill bit is operably coupled with the end pipe portion for drilling a borehole. Each pipe segment includes an outer conductor portion, a hollow inner conductor portion, and a dielectric portion for electrical isolation between the outer conductor portion and the inner conductor portion.

Abstract: A printhead assembly (100) suitable for a 3D bioprinter is disclosed, the printhead assembly (100) comprising at least one reservoir (106); a sample loading system (102) in fluid communication with the at least one reservoir (106), the sample loading system (102) configured to direct fluid into the at least one reservoir (106); and a dispensing system (103) having at least one dispensing outlet (126), the at least one dispensing outlet (126) in fluid communication with the at least one reservoir (106) and configured to dispense fluid from the at least one reservoir (106).
