| 20090235589 | BREAKAWAY ELEMENTS FOR A HORIZONTAL SIDE-MOVING DOOR - A horizontal side-moving door with a side-winding curtain or horizontally translating panel includes a breakaway brace that helps hold a relatively rigid leading edge of the curtain or panel in a substantially vertical orientation. Should a forklift accidentally strike the leading edge of the curtain or panel, a replaceable shear pin incorporated in the brace breaks away to release the leading edge, thus protecting the edge from damage. Although the shear pin can break into two or more pieces, the brace includes means for holding the pieces in place and preventing them from falling and hitting anything underneath the pin. Although with some limitations, the door is still operational even while the pin is broken. | 09-24-2009 |
| 20090236051 | BOTTOM SEALS FOR A HORIZONTAL SIDE-ROLLING DOOR CURTAIN - A sideways rollup door with a horizontal side-rolling curtain includes a replaceable bottom seal that is zippered or otherwise removably connected to the curtain at an inclined joint. The inclination of the joint ensures that the joint wraps upon the curtain's take-up roller in an approximate helical pattern so as to prevent the joint from creating a concentrated bulge on the roller. In some cases, there is extra space underneath the roller to provide roll-up room for the bottom seal, which can be relatively thick. Such extra space could be further used to accommodate a seal joint and/or other curtain seams that are not necessarily inclined. | 09-24-2009 |
| 20090236052 | PLIABLE SHROUDS FOR A HORIZONTAL SIDE-ROLLING DOOR - A sideways rollup door with a horizontal side-rolling curtain includes a vertical roller that is shielded by a pliable shroud. The shroud is supported by a frame that includes a breakaway feature and/or readily replaceable frame elements. To access the roller for servicing, the frame elements allow the shroud to be selectively moved (without the use of tools) between an installed position and a retracted position. In some cases, the breakaway feature enables the shroud to break away in certain directions easier than others. In some embodiments, the shroud includes a seal that engages the curtain when the shroud is in the installed position. | 09-24-2009 |
| 20100218429 | UPPER SEAL FOR A HORIZONTAL SIDE-MOVING DOOR - An example of a horizontal side-moving door with a side-winding or horizontally translating curtain includes an upper seal comprising an upper edge of the curtain sliding within a groove of a seal guide. To protect the door in the event of an impact, at least a portion of the curtain's upper edge can restorably pull out from within the groove. To avoid damage in certain situations, the seal guide might resiliently deflect as well. After an impact, the curtain's upper edge is automatically fed back into the groove by simply opening and closing the door. During normal operation, the curtain's upper edge advantageously deflects in response to air pressure against either side of the door. In some examples, the seal guide is of a uniform cross-section, which makes the seal guide easy to manufacture by way of a conventional plastic extrusion process. | 09-02-2010 |
| 20100218431 | WASHDOWN DOOR - An example of a door with a pliable curtain includes various washdown features that make the door particularly suitable for use in food and drug related environments that demand cleanliness. To prevent product contamination, such as bacteria and other microorganisms, some examples of the door include a curtain storage track with a spiral groove machined in a unitary block of plastic, a ventilated side frame with a removable curtain guide track and a removable seal, and various curtain seams that not only join multiple sheets of the curtain together but also promote and strategically direct liquid runoff to avoid creating water-holding surfaces and to prevent liquid from dripping on products passing through the doorway. | 09-02-2010 |
| 20120025964 | METHODS AND APPARATUS TO DETECT AND WARN PROXIMATE ENTITIES OF INTEREST - Systems and methods to detect and warn proximate entities of interest are described herein. An example signal generation system for a vehicle capable of different modes of movement includes a detector to determine at least one property of vehicle movement and an output representative of that at least one property and a selectively variable signal generator includes an input to receive the at least one output representative of the at least one property of vehicle movement and, responsively, generates a selected signal based on the received output. In some examples, a detector on a pedestrian detects the selected signal from the signal generator and, responsively, provides an output indicative of a vehicle in proximity to the pedestrian. In some examples, a trajectory vector is generated for at least two entities of interest based on at least one characteristic of movement of each entity. Each entity's trajectory vector is expanded and each entity's expanded trajectory vector is analyzed for overlap with the other entity's expanded trajectory vector to assess the possibility of a collision between them. | 02-02-2012 |

| 20100119582 | Device for the Treatment and Prevention of Disease, and Methods Related Thereto - Disclosed are implantable devices for delivering a drug into the blood stream of a vessel or into the vessel wall of a subject's body to treat or prevent vascular or cardiovascular disease, such as vascular plaque, cardiovascular plaque, and diseases attributable to inflammation, such as arteriosclerosis, diabetes, rheumatoid arthritis, and Alzheimer's disease. The devices of the present invention comprise a biodegradable matrix that degrades gradually and vanishes over a period of time, and have a ring-like, flag-like, or plaster-like configuration. The flag-like configuration comprises a holding structure and at least one flag. These flags are preferably elastic, and may be constructed from fibers, woven tissue, strings, sheets, or any combination thereof. Disclosed devices may comprise more than one drug, or varying concentrations of the same drug. Also disclosed are methods related thereto. | 05-13-2010 |
