Patent number: 7041141Abstract: A grip device for an artificial or prosthetic arm, including at least two opposable digits and a drive linkage powered by a drive motor. When the drive motor is powered it enables the two opposable digits to grip. The drive linkage includes a drive and transmission attached to the drive motor. A backlock is connected to the drive and transmission. Surrounding the backlock is a backlock housing which contains the drive, selected transmission elements, and a backlock. A stop element is also included for holding the backlock housing fixed with respect to ground. The stop element can be released to allow the backlock housing to move freely and to avoid power transmission without disrupting the operating structure of the transmission.Type: GrantFiled: February 21, 2002Date of Patent: May 9, 2006Assignee: Motion Control, Inc.Inventors: Edwin K. Iversen, James R. Linder, Steven R. Kunz, Arthur D. Dyck, Harold H. Sears

Patent number: 6424886Abstract: A movable prosthetic limb includes a drive linkage which is configured to move the prosthetic limb. An ultrasonic drive motor is coupled to the drive linkage and powers the drive linkage. The ultrasonic motor is non-backdrivable and has high torque at low speeds. Specifically, a prosthetic limb uses an ultrasonic motor to drive an elbow joint or prosthetic fingers. A movable prosthetic wrist includes a base configured to be coupled to an amputee. An ultrasonic drive motor is attached to the base, and a hand piece is attached to the ultrasonic drive motor to form a wrist joint. In this configuration, the ultrasonic drive motor directly moves the wrist joint. A harmonic drive can also be used for gear reduction in the wrist joint.Type: GrantFiled: October 17, 2000Date of Patent: July 23, 2002Assignee: Motion Control, Inc.Inventors: Edwin K.

Patent number: 5888213Abstract: The present invention relates to improved controllers for externally powered prosthetic limb devices or similar extension devices such as orthotic devices or a sensor probe device. The improved controller operates a highly-efficient, compact, reliable and low-maintenance tactile force feedback system for translating a sensed pressure force from a prosthesis contacting an object or surface into a tactile sensory feedback pressure force to the user. The tactile force feedback system comprises at least one contact-responsive transducer which translates a sensed contact pressure from a portion of an extension device which contacts an object or surface into a corresponding electrical signal. The electrical signal is received by a microprocessor and processed into a proportional output voltage for producing a proportional torque from a motor.Type: GrantFiled: June 6, 1997Date of Patent: March 30, 1999Assignee: Motion Control, Inc.Inventors: Harold H. Sears, Edwin K. Iversen, Kevin B. Hays, Arthur D. Dyck
