Filed:

Mar 2, 2000

Appl. No.:

09/517142

Inventors:

Donald E. Morris - Kensington CA 94707

International Classification:

A61B 500

US Classification:

600590

Abstract:

A system is provided for monitoring an undesired behavioral disorder such as bruxism, jaw clenching, or snoring. A processor correlates the monitored behavior with the onset of the undesired disorder. Since behavior of this type is typically subconscious, the sensor is preferably coupled to a warning device to alert the patient when he or she is performing the undesired behavior. Typically the warning device causes the patient to experience an unpleasant sensation, thus promoting the discontinuance of the behavior. In one embodiment the system determines which stimuli is most effective and therefore best suited for an individual patient. The system may further include means to record the monitored data related to the undesired behavioral disorders. This feature allows the patient to receive data related to the rate, duration, intensity, and time of day that the unconscious behavior occurred thus allowing the patient to correlate the undesired behavior with outside factors.

International Classification:

B60P 143

US Classification:

414537, 414921

Abstract:

A wheelchair ramp assembly ( ) is disclosed. The wheelchair ramp assembly includes a frame attachable to a vehicle having a floor, a platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform for reciprocating the ramp between a deployed position and a stowed position in response to a force. The reciprocating mechanism counterbalancing the weight of the ramp during actuation of the ramp between the deployed and stowed positions to reduce the force required to reciprocate the ramp between the deployed and stowed positions.

Appl. No.:

12/255625

Inventors:

Donald Morris - Conifer CO, US
David Johnson - Modesto CA, US

Assignee:

Lift-U, division of Hogan Mfg., Inc. - Escalon CA

International Classification:

E01D 1/00

US Classification:

14 713, 414921, 74 892

Abstract:

A counterbalance for a ramp assembly includes a chain assembly and a spring assembly. The spring assembly includes a spring and first and second spring fittings. The first spring fitting restrains a first end of the spring when the ramp portion is between a neutral position and the stowed position and moves the first end of the spring toward a second end of the spring when the ramp portion moves from the neutral position toward the deployed position. The second spring fitting is spaced from the first spring fitting and restrains the second end of the spring when the ramp portion is between the neutral position and the deployed position. The second spring fitting moves the second end of the spring toward the first end of the spring when the ramp portion moves from the neutral position toward the stowed position.
