Latest Patents

Del Rosario's latest patents include an "Apparatus for securing CCD board at a fixed position within a range of motion" and an "Apparatus for fixing the position of an optical sensor within a range of motion in relation to an optical apparatus." These inventions allow for a range of motion through five degrees of freedom (DOF) during the securing process. The apparatus features a housing for the optical assembly and a middle bracket that is secured to the optical apparatus. The gimbal design in the housing and middle bracket facilitates the five DOF. Notably, there are no screws involved in the fixing process, which prevents any torques or forces from affecting the alignment of the parts. An ultraviolet (UV) activated adhesive is utilized to secure the sensor housing to the middle bracket and the middle bracket to the optical scanner housing. The middle bracket is made from a material that is transparent to UV light, allowing a high percentage of UV light to pass through and cure the adhesive. A vertical hole runs through the tabs of both the housing and the middle bracket, where the adhesive is applied. This adhesive remains liquid during the alignment process, allowing for relative motion between the parts. Once alignment is complete, the adhesive region is exposed to UV light, curing it into a solid vertical column, which acts as a chemical rivet. This chemical rivet provides a strong mechanical interlock of the components, in addition to the adhesive bonding.
