Patent number: 10344523Abstract: A track-guided power door operator used to simultaneously open a set of opposing hinged doors is disclosed. The door operator comprises a pair of articulated arm linkages, each pair of which is pivotally mounted at one end to a vertically oriented pivot pin at one end of a guide member and pivotally connected at the other end to a vertically oriented pivot pin of a yoke member of a translating carriage, which is engaged by a horizontal lead screw. Translation of the carriage member due to rotation of the lead screw causes lateral separation between the knuckles of the articulated arm pairs to cause doors contacted by the knuckles to rotate about their respective hinges. The door operator may include a control unit to control operation of the doors. The operator may further include magnetic latches to lock the doors closed.Type: GrantFiled: October 19, 2017Date of Patent: July 9, 2019Inventor: John H. Staehlin

Patent number: 6029406Abstract: The seating arrangement of the present invention comprises a series of hingedly connected rigid platforms with a series of folding seats affixed to selected platforms. Beneath each series of folding seats are a series of hingedly connected folding panels connected to front and rear support frames. When collapsing the seating arrangement for storage, the seats are folded to their closed position and the folding panels fold inwardly, pulling the front and rear frames towards each other. The folding panels may be simultaneously folded by utilizing a member connecting one or more of these folding panels. Additionally, means may be provided for facilitating the collapsing of the seating arrangement from its use position to its compact, folded configuration.Type: GrantFiled: July 21, 1998Date of Patent: February 29, 2000Assignee: Volunteers for Medical EngineeringInventor: John H.

Patent number: 5988662Abstract: This invention relates to an improved lever driven bicycle including a shifting mechanism for controlling a drive ratio between the oscillating lever and the drive wheel. The drive lever arrangement may be located about the front or rear wheels of the bicycle and, when about the rear wheel, may include a sole lever or dual levers. The drive lever arrangement includes a drive lever, a force applicator, a shifting mechanism, and a force converter which together transform the oscillating displacement of the lever to a rotation of the drive wheel. The shifting mechanism includes a slide block located about the lever which engages with the drive lever upon downward motion of the drive lever and controllably slides along the drive lever upon upward motion of the drive lever. The position of the slide block corresponds to a drive ratio between the drive lever and the drive wheel.Type: GrantFiled: June 9, 1997Date of Patent: November 23, 1999Assignee: Volunteers for Medical EngineeringInventor: John H. Staehlin

Patent number: 5954673Abstract: A method for determining muscle strength of elements of the musculature used in speech and swallowing. In particular, a tool is equipped with at least one pressure sensor. A person inserts the tool into the person's mouth and utters sounds of speech or swallows. While uttering sounds of speech or swallowing, portions of the oral musculature contact and exert force on the sensor. A representation of this force is displayed at a visual display device as an indication of muscle strength and position.Type: GrantFiled: August 6, 1997Date of Patent: September 21, 1999Assignee: Volunteers for Medical EngineeringInventors: John H. Staehlin, Jack Light, Warren O'Reilly, Dan Buck, John Knight, Mike Robinson, Erick Figueroa, Forest Platt, Phil Atkinson

Patent number: 5704938Abstract: A bone lengthening mechanism is placed into a bone which is then lengthened by extending the mechanism. The mechanism is extended by effecting a rotational movement in a drive bolt which mates with a threaded portion in a section of the mechanism. The threads convert the rotational movement to a longitudinal force thereby lengthening the bone.Type: GrantFiled: March 27, 1996Date of Patent: January 6, 1998Assignee: Volunteers For Medical EngineeringInventors: John H. Staehlin, Gary I. Segal, David King, Guy Rubley, Dror Paley

Patent number: 5636640Abstract: An apparatus for sampling blood which includes a deformable housing defining a chamber that retains liquid. The housing has a pierceable membrane. The apparatus also includes a resilient piercer member that is adjacent the wall of a chamber and adapted to puncture the pierceable membrane. A removable layer that covers at least a portion of the pierceable membrane. Depression of the deformable housing proximate the piercer member urges the piercer member to puncture the pierceable membrane. The piercer member thereby forms an opening, allowing liquid to be drawn through the opening and into the chamber. Thereafter, the piercer member returns into the deformable housing.Type: GrantFiled: February 6, 1995Date of Patent: June 10, 1997Assignee: Volunteers for Medical EngineeringInventor: John H. Staehlin
