Abstract
A handheld thermal imager includes a housing defining a cavity. A lens barrel has a first end portion and a second end portion. The lens barrel is at least partially disposed within the cavity. A lens is coupled to the lens barrel first end portion. A resilient buffer member supports the lens barrel within the cavity. A thermal sensor is coupled to the lens barrel second end portion. A processing module receives signals from the thermal sensor. A display is coupled to the processing module for displaying a temperature characteristic of a scene.

A handheld thermal imager, comprising:
- a housing defining a cavity;
- a lens barrel having a first end portion and a second end portion, the lens barrel at least partially disposed within the cavity;
- a lens coupled to the lens barrel first end portion;
- a resilient buffer member supporting the lens barrel within the cavity, the resilient buffer member including a ring-shaped body, a first radial extension member connected to and extending perpendicularly from the ring-shaped body, and a second radial extension member connected to and extending perpendicularly from the ring-shaped body, the lens barrel supported within the housing by the first radial extension member and the second radial extension member;
- a thermal sensor coupled to the lens barrel second end portion;
- a processing module receiving signals from the thermal sensor;
- and
- a display coupled to the processing module for displaying a temperature characteristic of a scene,
- wherein the first radial extension member and the second radial extension member are connected to the housing, and
- wherein the first radial extension member and the second radial extension member reduce impact forces transferred from the housing to the lens barrel.
An imaging device, comprising:
- a housing assembly including a first housing member and a second housing member, the first housing member and second housing member defining a cavity;
- a lens barrel having a first end and a second end, the lens barrel at least partially disposed in the cavity;
- a resilient buffer including a ring-shaped body, a first radial extension member connected to and extending perpendicularly from the ring-shaped body, and a second radial extension member connected to and extending perpendicularly from the ring-shaped body, the ring-shaped body annularly disposed about the lens barrel between the first end and the second end, the first radial extension member and the second radial extension member coupled to the housing assembly to support the lens barrel within the cavity;
- a lens coupled to the lens barrel first end;
- and
- a thermal sensor resiliently coupled to the lens barrel second end and supported by the first housing member and not the second housing member,
- wherein the first radial extension member and the second radial extension member reduce impact forces transferred from the housing to the lens barrel.
