  • Patent number: 5984838
    Abstract: A treadmill with a preferred frame relates to a running track frame being anchored at the two sides of the mainframe that primarily used for accommodating and stabilizing a running board. And the front and the back of the running board is coordinated with front and rear rollers, and combined with a running track to provide the user to stand on top of the running track to perform the jogging motion. At this time, the running track will start to rotate repeatedly around the perimeter of the front and rear rollers due to abrasion. The characteristic is the particular runner frame has at least one opening slot, or equipped with an open slot on one of the surfaces, while the total length of that open slots shall exceed one-half of the distance between the front and rear rollers as an optimal choice. Therefore, the existence of that opening slot is utilized to provide adequate reduction to the rigidity of the metal structure in that framework, thus reduces the counter-force and vibrations during the operation.

  • Patent number: 5385474
    Abstract: A method of simulating anesthesiology and operating room conditions including the steps of displaying initial patient simulated vital sign information from a memory to signify an initial patient condition, randomly modifying the displayed patient vital sign information according to a script matrix in a manner analogous to that in which a patient's vital signs would be effected in the operating room by drugs and other external effects, thereby indicating a deteriorating condition, displaying user options, evaluating the timeliness and appropriateness of user input selections from the options in response to the changes in patient vital sign data, and causing the patient vital sign information to improve to its initial state or deteriorate to a critical state in accordance with the successive script blocks in the script matrix depending upon the user's response and timeliness.
