comprises a base, wherein the base has a first width, a first length, and a proximal surface, and an elongated portion, which is attached to the base, wherein the elongated portion has a second width, a second length, and a distal surface, wherein the first width is greater than the second width and the first length is less than the second length; and a Y-shaped fluid conduit comprising a central stem portion, a first prong portion, and a second prong portion, wherein the central stem portion extends from an entrance port on the proximal surface of the base through the base, wherein the first prong portion extends from a distal end of the central portion through the base to an exit port on the partially curved first side, and wherein the second prong portion extends from the distal end of the central portion through the base to an exit port on the partially curved second side. ### Claim 22 (depends on 21) The manifold of claim 21 further comprising a first channel extending from the base through the elongated portion, wherein the first channel has an entrance port positioned on said proximal surface of the base and an exit port positioned on the distal surface of the elongated portion. ### Claim 23 (depends on 22) The manifold of claim 22 further comprising a second channel extending from the base through the elongated portion, wherein the second channel has an entrance port positioned on said proximal surface of the base and an exit port positioned on the distal surface of the elongated portion. ### Claim 24 (depends on 23) The manifold of claim 23 further comprising a third channel extending from an entrance port on the proximal surface of the base through to an exit port on the partially curved first side. ### Claim 25 (depends on 24) The manifold of claim 24 further comprising a fourth channel extending from an entrance port on the proximal surface of the base through to an exit port on the partially curved second side, wherein each of the first channel, second channel, third channel, and fourth channel are fluidically isolated and separated from each other. ### Claim 26 (depends on 25) The manifold of claim 25 further comprising a fifth channel extending from the base through the elongated portion, wherein the fifth channel has an entrance port positioned on said proximal surface of the base and an exit port positioned on the distal

defined by a housing that is substantially cylindrical with a substantially flat front face, a first curved side face, and a second curved side face. ### Claim 36 (depends on 35) The manifold of claim 35 wherein said interior volume further comprises a front image sensor, defined by a first optical axis, having a lens and an electrical assembly, wherein the lens is positioned on a surface of said substantially flat front face. ### Claim 37 (depends on 36) The manifold of claim 36 wherein said interior volume further comprises a first side image sensor, defined by a second optical axis, having a lens and an electrical assembly, wherein the lens is positioned in the first curved side face. ### Claim 38 (depends on 37) The manifold of claim 37 wherein said interior volume further comprises a
