Stereolithographically fabricated conductive elements and semiconductor device components and assemblies including these conductive elements. The electrical connector for use in a compact space, the electrical connector being flexible and inexpensive, and well suited for use in a vehicle fuel cell electrical system is disclosed. The masked data segments are communicated to a processor for processing. Each power source unit is connected to each light emitting element array in series, and supplies constant current to each light emitting element. In addition, the small cell backhaul network’s components namely a small cell radio base station, a small cell hub, a small cell backhaul controller, and a small cell backhaul storage unit are described herein. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient’s vasculature.
