20080257672, Oct 23, 2008

Filed:

Jan 13, 2004

Appl. No.:

10/586034

Inventors:

Fred P. Smith - Alpine UT, US
John H. Atkinson - Provo UT, US

International Classification:

B60T 1/00

US Classification:

188 4 R

Abstract:

A single unit of the new deployment system includes a housing to which an electric drive motor is externally mounted. The deployment system for each vehicle requires at least a pair of deployment units: one each for right and left wheels. Each unit includes a reversable electric drive motor having an armature shaft; an intermediate drive shaft; a worm axially affixed to the intermediate drive shaft; an output shaft; a shock damper affixed to the output shaft; a worm gear affixed to the shock damper, the worm gear meshing with the worm, and providing rotational locking for said output shaft; and a deployment arm coupled to the output shaft, the deployment arm having rotatably mounted thereto a friction drive disc, said friction drive disc having peripherally attached thereto a plurality of chain segments. Torque applied to the output shaft by the electric motor is limited either by a spring-loaded clutch axially mounted on the intermediate drive shaft or by a circuit which limits current drawn by the electric drive motor to a preset maximum.

Inventors:

John H. Atkinson - Provo UT

International Classification:

B60T 100

US Classification:

188 4B

Abstract:

An improved snow chain system for wheeled vehicles that can be rapidly deployed and rapidly retracted, includes a rotatably-mounted friction drive disc having a circumferential edge that is pressure biased against the sidewall of a tire. Multiple arcuate chain attachment plates, which interlock much like a laminar puzzle, are placed end-to-end to form a ring-shaped unit. The ring-shaped unit is held together and to a planar surface on the friction drive disc by a plurality of bolts, each of which passes through a single attachment plate and through the friction drive disc. Each arcuate attachment plate has either one or two chain segments attached thereto. In the case where only a single chain segment is attached, a U-shaped anchoring chain link is welded to the attachment plate. In the case of attachment of a pair of chain segments, a M-shaped anchoring link is employed. The invention facilitates replacement of individual chain segments or chain segment pairs while retaining structural integrity of the circular ring.

International Classification:

H04L 9/08
H04L 9/14

Abstract:

Apparatuses, methods, systems, and program products are disclosed for secure data handling and storage. A method includes receiving a plurality of keys for unlocking an encryption engine. Each key may be associated with a key holder. At least a subset of the plurality of keys are combined to generate a master key. An encryption engine is unlocked using the master key. Encrypted data is received at the encryption engine on a continuous basis. The encrypted data is encrypted using a first encryption key, and includes sensitive information for one or more users. The encrypted data is decrypted using the first encryption key. The decrypted data is re-encrypted using a second encryption key that is newer than the first encryption key.

Appl. No.:

14/073847

Inventors:

Shane Evan McKenna - Draper UT, US
John Horace Atkinson - Provo UT, US

International Classification:

B60C 27/00

US Classification:

152214

Abstract:

A unit for rapid deployment and retraction of chain traction systems for vehicles includes a pneumatic cylinder having a cylindrical chamber enclosing a piston that is pneumatically-movable bidirectionally. A control rod coupled at one end to the piston passes through an end of the chamber and is coupled to a rack linearly movable within a sealed, grease-containing case. The rack is formed from a series of equally-spaced roller pins secured between parallel walls of a rack frame. The roller pins of the rack engage a sprocket affixed to a rotatable shaft to which is rigidly coupled an actuator arm of the rapidly-deployable vehicle ice and snow chain traction system. As the rack is moved back and forth, the actuator arm swings through an arc that—depending on the displacement of the control rod and the length of the rack, can be greater than 180 degrees.
