Intraoral X-ray sensor with embedded standard computer interface
First Claim
1. An intraoral x-ray sensor comprising:
- a sensor housing having a top portion and a bottom portion;
a twisted-quad universal serial bus (USB) cable coupled to the top portion, the twisted-quad USB cable including an outer sheath;
a first data line, a second data line, a ground line, and a power line positioned within the outer sheath and twisted together to form a single bundle; and
circuitry within the sensor housing that converts x-rays received through the bottom portion into x-ray data and outputs the x-ray data along the twisted-quad USB cable, andwherein the outer sheath includes a shield and is coupled via a heat-conducting path to a metallic layer substantially covering an inner surface of the top portion, andwherein the heat-conducting path has a thermal resistance that is less than the thermal resistance of air.

Abstract
An intraoral x-ray sensor with embedded standard computer interface. The sensor includes a data transfer cable with improved mechanical strength and heat transferring properties. The cable is quad-twisted USB cable and includes two data lines, a ground line, and fillers twisted within a metallic sheath, e.g., a metal braided shield. The cable is symmetrically organized about a centerline. The symmetric cable has an improved life due to the ability to withstand mechanical stress (e.g., rotational stress). The sensor includes a processor and a housing with an inner metallization layer. The sheath is coupled to the inner metallization layer to transfer heat generated by the processor from the inner metallization layer to the sheath.
