A hunting blind and method of use thereof, comprising a cylindrical mount having a tube disposed therethrough. The cylindrical mount attaches to a tree or other suitable object via straps, bungee cords and / or a hook. The tube comprises angled holes into which support tubes supporting screen panels are inserted. The support tubes are sectioned so as to enable disassembly for packing into a compact arrangement by rolling up same within the screen panels. The screen panels have extensions that can be secured together via cords. Alternate embodiments are directed to the addition of a mesh panel above the screen panels and extensions; a ground-based stand, wherein the screen panels and extension are secured to the ground via tent stakes; and a wheelchair stand, wherein a framework on the wheelchair carries the support tubes, panels and extensions of the preferred embodiment.

A backpack blower has a lightweight engine, a starter, a fuel tank, a fan, a frame for the engine, two hollow tubes, and a control mechanism upon one tube. The blower improvement comes from a housing and two elbows. The round housing contains the fan and has two tangential outlets. The two elbows have a generally round cross section and a generally right angle shape. On each elbow, the first end connects with an outlet and the second end joins a tube. The elbows rotate and bend, directing leaves and debris with airflow from the tubes.

This invention relates to novel photochromic and electrochromic monomers and polymers based on 1,2-dithienylcyclopentene derivatives and method of using and synthesizing same. The compounds are reversibly interconvertible between different isomeric forms under suitable photochromic or electrochromic conditions. The electrochromic conversion may be catalytic. The application also relates to ultra-high density homopolymers prepared using ring-opening methathesis polymerization (ROMP) where the central ring of the 1,2-bis(3-thienyl)-cyclopentene is incorporated directly into the polymer backbone. The monomer units may be readily functionalized to enable the synthesis of polymers with diverse structural and electronic properties. The compounds have many potential applications including high-density optical information storage systems, photoregulated molecular switches, reversible holographic systems, ophthalmic lenses, actinometry and molecular sensors, photochromic inks, paints and fibers and optoelectronic systems such as optical waveguides, Bragg reflectors and dielectric mirrors.

An autostereoscopic display having an improved 2D / 3D mode switchable structure, including a display device to display an image, and a parallax barrier unit to transmit all incident light in a 2D mode and to separate a left-eye image and a right-eye image by forming a barrier in a 3D mode. The parallax barrier unit includes a polarizer to transmit light having a predetermined polarizer polarization direction, a first plane array including first and second birefringent elements, which change a polarization direction of light transmitted through the polarizer into a first direction and a second direction opposite to the first direction, respectively, and a second plane array including third and fourth birefringent elements, which change a polarization direction of light transmitted through the first plane array into a third direction and a fourth direction, that is opposite from the third direction, respectively.

A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.

A tilt mechanism provides improved coordination in the motions of a chair seat and a chair back during chair tilt. In one aspect, the tilt mechanism includes a seat base, a back bracket, a back support bar, a guide track and a back follower member. The seat base is slidably coupled to the chassis and rigidly coupled to the chair seat. The back support bar is configured for moveable engagement with the back bracket coupled with the chair back. Additionally, the back follower member, coupled with the chair back, is received within one or more channels formed in the guide track for moveable engagement therewith. A proportional and asynchronous action is achieved via the back bracket moving relative to and in engagement with the back support bar, the back follower member moving within the guide track and the seat base sliding forwardly relative to the chassis.

An automatic clutch for automotive and other applications employs a control rod to manually control engagement and disengagement of the clutch independently of its speed of rotation, and in one form of invention can be employed in manual start motorcycles to engage the clutch for bumpstarting purposes before the engine is up to speed, and in an alternate form a control rod can be employed in electrically started bikes to lock the clutch against engagement whether or not the engine is up to the speed required for automatic engagement of the clutch. The control rod may either extend through the transmission shaft from one end of the clutch housing or may extend through the opposite end of the clutch housing, and in certain applications the hereinbefore described control rods can be combined to selectively control bumpstarting to manually effect clutch engagement or as a locking mechanism to prevent clutch engagement.

A container and method of using the container to maintain an excised tissue specimen in a fixed orientation during transport and imaging is described. The container includes a body, a flexible, soft retainer capable of holding various sized specimens, an adjustable soft retainer that interacts with the body to retain the specimen against the soft retainer without significant compression or distortion, and a lid that snaps tightly to the body reducing bodily fluid leakage when the container is placed in a horizontal position, and preventing contamination of the specimen.

A structural panel for use in building structures or in the formation, finish or decoration thereof includes an outer sheet and a connector sheet with a plurality of collapsible or compressible dividers therebetween. The panel in a rest condition is expanded and of a desired thickness for final use but can be compressed into a relatively thin thickness or profile for shipping purposes. The panel is very lightweight but structurally strong and can be selectively bent in one transverse direction if desired. The panel can be easily cut or formed into any predetermined size or shape.
