Abstract:
An arm motion assembly for an exercise device includes a first link which is pivotally affixed to a frame portion of the exercise device at a first pivot point so as to be capable of reciprocal motion thereabout. The assembly includes a second link which is pivotally affixed to a second frame portion of the exercise device at a second pivot point separated from the first pivot point so that the second link is capable of reciprocal motion about the second pivot point. The assembly includes a connector link which extends between the first link and the second link. The connector link is pivotally joined to the first link at a first junction point and to the second link at a second junction point so that when one of said first links and said second links reciprocates about its respective pivot point the connector link causes the other of said links to pivot about its respective pivot point. The assembly includes a handgrip which is affixed to the connector link or to one of the first and second links.
Abstract:
A method and an apparatus providing high level signals by summing partial signal currents and magnetomotive forces. In one embodiment, an isolation transformer having a 1:1 turns ratio and a plurality of separate primary windings is utilized. A plurality of independently controlled current generators are coupled to each separate primary winding with appropriate terminations such that the data communications circuit is impedance matched across the entire system. The isolation transformer sums the partial currents and magnetomotive forces in each separate primary winding such that a higher level high quality signal is produced in the secondary winding. As such, high quality high level data communications signals are produced with the described data communications circuit from low voltage level signals.
Abstract:
A hydraulic strut for use with a vehicle suspension system includes a reciprocating piston rod and piston in an inner cylinder. A piston valving assembly is carried by the piston and controls the flow of fluid between upper and lower chambers of the inner cylinder. A base valving assembly controls the flow of fluid from the inner cylinder to a reservoir. A bypass valving assembly, selectively dependent upon a rotation movement input when the vehicle is steered, permits fluid flow to travel between the upper and lower chambers of the inner cylinder without traveling through the piston valving assembly.
Abstract:
A door assembly with a frameless window has a window regulator mechanism for raising and lowering the window and which includes a guide arrangement for stabilizing the window in all directions when being raised and lowered and which causes the upper end of the window to be moved away from its associated seal and the lower end thereof to be moved toward the inner door panel about a belt line pivot point upon being lowered while simultaneously causing the window to be moved longitudinally of the door, and vice versa, upon the window being lowered and raised, respectively.
Abstract:
A window guide arrangement for a door assembly of an automotive vehicle has a pair of one piece guide tracks and a pair of guides having spaced guide pins secured to a movable window and cooperatively received on the tracks and in which the guide tracks and guides are constructed and arranged such that they guide the window so that its inner side engages a seal and so that its top and lower ends are moved inwardly against the seal and outwardly of the door, respectively, when the window approaches its closed position so that its exterior is substantially flush at all sides with the adjacent exterior surfaces of the vehicle and door assembly.
Abstract:
An improved and simplified pill dispenser for patients required to take medication comprising a plurality of compartments (A, B, C, and D of FIG. 1) each containing one or more different kinds of pills but all of such pills falling into a class of pills having the same daily morning start-up time and the same time interval between the taking of each pill, a real time clock (RTC) (28), a control panel (FIG. 2) unique to each compartment and comprising, first and second indicators (19 and 20 of FIG. 2) for indicating, respectively, the morning start-up time and the time interval between taking pills, and a time readout indicator (18 of FIG. 2) indicating when the next pill is to be taken. Also provided are a comparator (170 of FIG. 6) for comparing the RTC time with the contents of the readout indicators, an alarm (203 of FIG. 6) responsive to the coincidence of the real time and the contents of the readout indicator to alert the patient to take his pills, a first energizer for transferring the contents of the start-up time indicator (20 of FIG. 2) to the readout indicator at the patient's bedtime, and other energizers (12 and 14 of FIG. 2) energizable by the patient to selectively transfer either the contents of the RTC to the time readout indicator and then add the time interval in the second indicator (19 of FIG. 2) to the contents of the time readout indicator (18 of FIG. 2) or, alternatively, to simply add the time interval to the contents of the time readout indicator (18), depending on how long before or after coincidence between the RTC time and the contents of the time readout indicator ocurred after the other energizers were energized.
Abstract:
An exercise device has a frame supporting guide links to which foot support links are pivotally attached. An arc center drive assembly is provided to raise and lower the foot receiving areas of the foot support links. Vertical drive elements couple a crank system to the arc center drive assembly to control the raising and lowering of the foot receiving areas.
Abstract:
An elliptical exercise device has a frame and guide link pivotally attached thereto. A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. Vertical control tracks are pivotally connected to the frame and support the foot support links. A vertical drive is coupled to the forward portion of the frame and vertical control elements connect the vertical drive to the vertical control tracks. A horizontal drive and horizontal control links control pivoting of the guide links.

A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. A cam drive has cams supported for rotation about an axis of rotation and pivoting arms each engaging one of the cams such that rotation of the cams causes movement of the pivoting arms. Flexible elements couple the foot support links to the pivoting arms such that rotation of the cams moves the foot receiving areas of the respective foot support links in a path of travel having a vertical component of motion. A crank and horizontal control links control pivoting of the guide links.
