Claim 17:
18. A device comprising:
a first portion comprising an elongated tube, wherein the elongated tube extends in a first direction and comprises a proximal end and a distal end, opposite the proximal end, a smooth outer surface, and an interior tubular space, and
the interior tubular space comprises a first cross-section transverse to the first direction, and the first cross-section comprises a first length,
a sensor head, coupled to the distal end of the elongated tube, wherein the interior tubular space of the elongated tube extends from a first opening at the proximal end of the elongated tube to the sensor head,
the sensor head comprises a first structure and a second structure, the first structure is an emitter, and the second structure is a detector,
a printed circuit board comprising a current-to-voltage converter circuit coupled to the detector, wherein the printed circuit board comprises a first surface on which components of the current-to-voltage converter circuit are formed, and a plane of the first surface is parallel with the first direction, and
an electrical conductor, coupled to the current-to-voltage converter circuit; and
a second portion, coupled to the first portion at the proximal end of the elongated tube such that the device is a handheld device, wherein the second portion comprises a first enclosure having a second cross-section transverse to the first direction, and the second cross-section comprises a second length that is larger than the first length,
the first enclosure comprises
an analog-to-digital converter circuit, coupled to the second structure of the sensor head, wherein the electrical conductor extends from a first end of the printed circuit board through the interior tubular space of the elongated tube to couple to the analog-to-digital converter circuit, and
an interface circuit, coupled to the analog-to-digital converter circuit.
