A system includes a robotic arm, a rotisserie control linkage, and a computer system. The robotic arm includes a touch probe and laser head. The rotisserie control linkage is configured to couple to a transport cart. The computer system is communicatively coupled to the robotic arm and the rotisserie control linkage and is configured to control the system to probe, using the touch probe of the robotic arm, a transparent outer layer of an aircraft canopy located on the transport cart in order to determine surface measurements of the aircraft canopy. The computer system also controls the system to ablate, using a plurality of predetermined parameters and the laser head of the robotic arm, an interface layer located between the transparent outer layer and the aircraft canopy, wherein movements of the robotic arm during the ablation are based on the surface measurements.

Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.

A pulsed laser printing module for a contact lens, comprises a steel mold, a pulsed laser device and a forming case. The steel mold is configured for transferring pigment. The pulsed laser device is configured for transmitting ultrashort laser pulses having pulse time widths less than 10.sup.−9 seconds. The ultrashort laser pulses etch the surface of the steel mold to remove a coating of the steel mold to form an etched layer. The forming case has a lower member and an upper member. The lower member is a concavity, and an inner surface of the lower member is provided with a lower curved surface. The upper member is provided with a protrusion corresponding to the lower member, and an outer surface of the protrusion is provided with an upper curved surface corresponding to the lower curved surface. The protrusion is capable of being placed in a concavity of the lower member to form a gap between the lower curved surface and the upper curved surface.
