Patent number: 9004204Abstract: A lightweight motorized and tracked sled for attachment to a variety of stair chairs is described. A power supply or power source provides power to a motor driving a track configured to engage a set of stairs. The motor and track can lift and support the stair chair and a patient thereon up or down one or more flights of stairs. The track driven by the motor has a length sufficient to simultaneously engage the lips or edges of a pair of sequential steps, but may be otherwise limited in length to reduce the weight of the track. To ensure that the sled and attached stair chair are stably supported while ascending or descending stairs, the sled may have rails, skis, or passive tracks having a length sufficient to ensure that the rails, skis, or passive tracks are always over the edge or lip of no fewer than two steps.Type: GrantFiled: December 5, 2013Date of Patent: April 14, 2015Assignee: Stryker CorporationInventors: Nathan R.

Publication number: 20080272629Abstract: A collapsible emergency vehicle chair cot that includes a support system and a movement system is described. The movement system is coupled to the support system and utilizes rotational movement to assist in moving the chair cot over a surface. The support system and movement system are configured to be collapsible to facilitate using the chair cot with an emergency vehicle. The chair cot may include at least two removable platforms for supporting a patient in a seated position. Furthermore, the chair cot may include one or more options for transporting equipment, including an equipment transport basket that may take the place of the removable platforms.Type: ApplicationFiled: May 8, 2008Publication date: November 6, 2008Inventors: Nathan R.

Publication number: 20070182220Abstract: The present invention relates to a collapsible emergency vehicle chair cot that includes a support system and a movement system. The support system is a retractable system disposed on the bottom of the cot to support the chair cot during transportation. For example, one embodiment of a support system includes a track that extends from the bottom for the chair cot. The track supports the chair cot thereby minimizing the need for an emergency worker to manually support the chair cot during transportation. The movement system is coupled to the support system and utilizes rotational movement to assist in moving the chair cot over a surface. For example, one embodiment of a movement system includes coupling a motor system and a brake system to the support system to provide motorized movement. The support system and movement system are configured to be collapsible to facilitate using the chair cot with an emergency vehicle.Type: ApplicationFiled: April 11, 2007Publication date: August 9, 2007Inventors: Nathan Walkinshaw, Tad Clark, Mark Wenzel

Patent number: 7014113Abstract: A graphical code reader is disclosed. The graphical code reader includes an image sensor. A first lens is provided for focusing light reflected from a graphical code to form a first image on a first region of the image sensor. A second lens is provided for focusing light reflected from the graphical code to form a second image on a second region of the image sensor. The first lens is separated from the image sensor by a first distance, and the second lens is separated from the image sensor by a second distance. The first distance is greater than the second distance. A decoder is also provided for processing image data to obtain information contained in the graphical code.Type: GrantFiled: August 18, 2003Date of Patent: March 21, 2006Assignee: The Code CorporationInventors: George Powell, Blake Crowther, Ryan Hyde, Mark Wenzel, Paul J.

Patent number: 6481432Abstract: A paintball hopper for connection to a paintball launcher or marker has a counter which includes a flexible potentiometer extending into a transfer conduit that connects to the paintball launcher or marker. The hopper has a reservoir shaped for movement of the paintballs toward the transfer conduit. The hopper has a nose with slanted surfaces that are deflection engineered to enhance the deflectability of paintballs directed at the user. The counter mechanism includes a timer and an LCD display so the user can see how many paintballs have been launched and monitor time. The hopper also includes an agitator to agitate the paintballs in the reservoir.Type: GrantFiled: April 19, 2001Date of Patent: November 19, 2002Assignee: American International Marketing, Inc.Inventors: Ennis Rushton, Douglas M. Odom, Mark Wenzel, Joseph Harris, Gregory Misbach, Gordon B. Langford
