Patent number: 11002073Abstract: The present disclosure includes a retrofitted door brake cam. The retrofitted door brake cam may, in various embodiments, comprise a hub comprising a cylindrical central axle, a plurality of projections extending radially away from an outer circumference of the central axle, and/or a cam comprising a plurality of pins that hold the projections away from a channel wall of a brake housing. The pins may be configured to break away from the cam to release the projections into contact with the channel wall, and the pins may be fitted with a cover, such that the pins are capable of withstanding abrasion and wear. The cover may comprise a cylinder having an axially running aperture, and/or a beveled edge that shaves a layer of the outer surface from one of the plurality of pins as it is fitted over the pin.Type: GrantFiled: December 14, 2018Date of Patent: May 11, 2021Inventor: David Lueker

Patent number: 9752382Abstract: The present disclosure includes a system and article of manufacture for a door assembly for rolling and unrolling, or retracting and extending, a door curtain. The door assembly may include various mechanisms to protect a door curtain from wear and abrasion, as well as muffle noise associated with the operation of the door curtain. The door assembly may comprise a curtain shaft. A door curtain may roll and/or unroll (e.g., open and/or close) on the curtain shaft. The door assembly may further include an insulator shaft, which may receive or hold a door curtain insulator or insulators. A door curtain insulator may attach to the insulator shaft as well as the curtain shaft and/or door curtain itself. In operation, as the door curtain is rolled up, one or more lengths of insulator may be unrolled from the insulator shaft and layered, or interleaved, between consecutive layers of rolled up door curtain.Type: GrantFiled: January 5, 2016Date of Patent: September 5, 2017Assignee: CORNELL IRONWORKS ENTERPRISESInventor: David Lueker

Publication number: 20160156248Abstract: The present disclosure includes a system and article of manufacture for a low profile motor. The low profile motor can include a motor housing, a hub, an annular gear train encircling the hub, a rotor encircling the annular gear train, and a stator encircling the rotor. The orientation of the hub, the annular gear train, the rotor, and the stator is concentric, providing a low profile motor assembly with various benefits such as higher torques and advantageous braking. The gear trains that are efficient, reduce the profile or overall volume of the motor assembly, and reduce torsional reactions and coaxial shifting. Such motor assemblies may also have gear trains that more effectively distribute the load in the gear train and thus, torque capability.Type: ApplicationFiled: December 1, 2014Publication date: June 2, 2016Inventor: David Lueker

Patent number: 8919718Abstract: An apparatus including one or more beverage container receptacles for holding a beverage container in the upright position in multiple convenient and possibly unstable locations is described. Slender legs separate the beverage container receptacles from direct contact with the mounting or bearing surfaces and serve to damp spilling forces transmitted from these surfaces when the apparatus is placed in various horizontal or vertical orientations such as vertically between couch cushions; or horizontally between a bed mattress and box spring; or on a picnic blanket. Multiple stemmed and non-stemmed beverage container types such as wine glasses, coffee cups, large soda cups are simultaneously held. Additional storage space for personal effects such as digital electronic devices, remote controls or reading glasses is included. One embodiment of the invention includes speakers, amplifying electronics and batteries for playing digital music from a users digital electronic device.Type: GrantFiled: November 18, 2012Date of Patent: December 30, 2014Inventor: Mark David Lueker
