Abstract: A strobe module can include a Fresnel lens that defines an external surface of the strobe module and a sidewall at least partially defining an internal volume and defining an external channel. A gasket can be disposed in the external channel. A substrate can be coupled to the sidewall to further define the internal volume and a light source can be disposed on the substrate in the internal volume.

Abstract: A hypodermic interface assembly is disclosed. The hypodermic interface assembly includes a hub, a cannula, and a cannula carrier. The cannula carrier is non-removably-connected to the cannula. The cannula carrier is controllably separable from the hub.

Abstract: A heat exchanger tube for an automobile cooling system comprising a first end, a second end and a wall formed from a unitary sheet of formable material. The wall has an outer surface and an inner surface and includes a first side and a second side spaced apart and parallel to one another extending longitudinally between the first end and the second end, a first distal end, a second distal end, a first edge, a second edge, a first partition, a second partition and a compound partition extending between the first and second sides longitudinally between the first and second ends and defining four fluid channels extending longitudinally between the first and second ends.
