Abstract: The present invention is a device and method for assuring “chain of custody” (CoC) in connection with a home sleep study (HST). An HST CoC device according to the invention includes a camera and a circuit board operatively connected to the camera. During the HST the circuit board signals the camera to periodically take images of the patient, to optimally assure CoC. The images are preferably still shots, but can alternatively be relatively short video clips. Further, the images are preferably taken randomly to discourage the patient from attempting to game the system and defeat CoC safeguards. Another embodiment includes a shipping container for a HST device, wherein a CoC device is operatively connected to the shipping container, whereby the CoC device is automatically returned to the lab along with the HST device following the HST.

Abstract: A system for detailing vehicles, including an elongate flexible tool (26, 28, 30) having first and second ends. A cloth or absorbent material (32) can be attached to the tool first end, and the second end of the tool can be grasped and manipulated to clean remote areas on the vehicle. The tool is preferably between about 10 and 20 inches long, and can be in one of several configurations, including a pointed flat paddle design, pointed rod, and/or a slotted rod. The latter in particular can be driven by a drill motor to speed up the detailing procedure. A kit according to the invention can also include a mesh bag (33) to store and wash the various cleaning cloths; and one or more broad area cleaning devices, e.g., a lamb's wool duster (25) and/or a mini-mop (22).
