Abstract: Devices for supporting and/or positioning a martial arts board, or other strikeable object, are described. In one embodiment, the device includes a frame and a support assembly securing the board to the frame. The support assembly may include a pivotal retainer to facilitate rapid insertion and securing of a martial arts board by the device. In one embodiment, the device includes a rotational assembly configured to rotate the martial arts board and/or a tiltable assembly configured to tilt the martial arts board at an angle. Rotation and tilting may facilitate positioning of the board so that an individual is able to strike the board. In another embodiment, the device is modular and may be disassembled for transportation or storage.

Abstract: An automated nucleic acid compaction device for analyzing and compacting a nucleic acid complex into unimolecular nucleic acid particles. Broadly, the device includes a container support and agitation system; a measuring and testing system; and a dispensing system; all controlled by a control system. The control system controls the support and agitation system and the dispensing system based either on a predetermined formulation or by analysis of feedback data provided by the measuring and testing system. In a preferred embodiment, the device is a real-time measuring and mixing instrument operating in a closed loop system. The preferred embodiment also comprises a monitoring system including a submersible probe which is positioned in the batch solution to provide data to a controller. Once a desired level of nucleic acid compaction is reached, as detected by the monitoring system, the controller stops the dispensing and mixing agitating systems.
