Abstract: The present invention generally relates to the field of medical services and more specifically to the area of chronic disease management. It comprises a new method for providing a disease management service which utilizes nurse practitioners to engage in regularly scheduled virtual evaluation and management “office visits” with patients, using off-the-shelf videophones for real-time video and audio communications. As these disease management services are delivered to the patient while he remains in his home, such convenient access to professional health care brings about a much closer monitoring of the patient's condition than would be otherwise practical, enabling clinicians to make necessary therapeutic modifications in a timely fashion. Engaging patients in such regularly scheduled office visits also causes increased compliance with recommended regimens and lifestyle modifications, resulting in overall improved management of the patient's chronic condition.

Abstract: A safety control system for a snowmobile engine provides a switch which senses the position of the carburetor control element, and a second switch which responds to the presence of the operator's hand on the throttle lever. The switches operate to short-circuit the ignition coil of the engine in the event of a malfunction so that, if the carburetor throttle remains stuck open after the pressure on the throttle lever has been momentarily released, the engine will be killed.
