In at least one embodiment of the disclosure, a projector includes a light shield unit that shields a portion of a light emitted from a light source. Furthermore, the heat-conducting films are separately attached and so configured to an inner side surface of each of two heatsinks. The second end of the elongate tunneling member includes a coupling segment adapted for securely engaging a catheter. An electrically insulating sleeve surrounds at least part of the probe element. SIMD processing element cells are controlled by the configurable VLIW controller through the reconfigurable communication and control fabric via the interface. The design combines the use of auxiliary parallelograms with springs to produce an orthotic device wherein the total potential energy of the system is constant during standing and sitting motion.
