MEASUREMENT DEVICE FOR ELECTRICAL INSTALLATIONS AND RELATED METHODS
First Claim
1. A measurement device comprising:
- a housing adapted to be hand-held by a user;
a logic device adapted to determine a physical parameter associated with an external article;
an infrared imaging module adapted to capture an infrared image of a scene; and
a display fixed relative to the housing and adapted to overlay information indicative of the physical parameter onto a user-viewable image, converted from the captured infrared image, to display the information and the user-viewable image for viewing by the user.

Abstract
Techniques are disclosed for measurement devices and methods to obtain various physical and/or electrical parameters in an integrated manner. For example, a measurement device may include a housing, an optical emitter, a sensor, a distance measurement circuit, a length measurement circuit, an electrical meter circuit, a display, an infrared imaging module, and/or a non-thermal imaging module. The device may be conveniently carried and utilized by users to perform a series of distance measurements, wire length measurements, electrical parameter measurements, and/or fault inspections, in an integrated manner without using multiple different devices. In one example, electricians may utilize the device to perform installation of electrical wires and/or other tasks at various locations (e.g., electrical work sites). In another example, electricians may utilize the device to view a thermal image of one or more scenes at such locations for locating potential electrical faults.
