A golf mat includes artificial grass fibers attached to and extending upward from a backing material, which may be one or more layers. The artificial grass fibers include groups of at least two different kinds of fiber sewn through a common path in the backing material. One of the kinds of fibers in each group is shaped so as to appear like a blade of grass.

The lateral excursions cause portions of one such pre-stressed fiber to overlap and interfere with another, forming a mesh. The height of the pre-stressed fibers in their relaxed state in the turf is less than the height of the relatively unstressed artificial grass fiber(s). The crimped fibers form a resilient mat with impact characteristics similar to natural turf.

The present shoulder strap and waist belt invention is conceived to help the person who must carry weight comfortably and access the contents while carrying that weight. A person practiced in the art may imagine a number of deviations in the scope of this invention. One imagined deviation is a substitution of the bag for a more shelf-like creation which would be useful to people with injuries that need time for rest, such as an injured arm: Additional padding, webbing, and means of attachment of additional pieces could allow superior rest for the injured limb. Other deviations come to mind: a child carrier; a dog or other small pet carrier; a book or papers carrier without the external bag but instead with a grill-like cage or other means of containment, and others. As new raw materials are invented, substitutions may be made while using or otherwise keeping the ideas of the present invention. While the embodiment of the present invention teaches a soft bag with a small rigid section, a more fully rigid or completely rigid case may be imagined by one practiced in the arts, including a more rigid system of attachment of the case to the waist belt. Gel materials with imbedded shorter pieces such as aluminum, a pliable plastic, and other materials may be imagined, along with, or independent of, additional constructions and material changes as may be imagined by one practiced in the arts. The ability to carry weight comfortably while accessing the contents regularly will be of importance to walking delivery people, but utilization of this invention may well be more expansive. The current messenger bag trend may wane, and people young and old who are attracted by the informality of messenger bags but who want more comfort, may use the present shoulder strap and waist belt bag invention for school, work, and travel.

A simplified rear suspension for a bicycle or the like comprises a wishbone seatstay structure. The wishbone structure is provided with a first extension extending toward the seat junction. A low friction guide component, for example a spherical element, is provided at the distal end of the extension. A second extension is provided at the seat junction, with a hollow interior for receiving the guide component. The guide component slides with little friction and play within the hollow interior. A stop member may also be provided within the hollow interior, stopping travel of the guide component under load. Motion of the rear wheel (via dropout) relative to the main frame (e.g., from the terrain) is translated into motion of the guide component within the hollow interior. The chainstays, in a pivotless arrangement, provide a moment which acts as a spring, resisting the motion of the dropouts and providing shock absorption and / or damping for improved ride and control.

A material and method for production of ballistic armor. One or more absorbing layers are inserted between layers of woven cloth made of high strength fibers. Mechanical energy absorbing layers are of two types, either a large number of small objects in loose contact with one another which will dissipate energy by moving traversely to the direction of impact, embedded in a matrix along with randomly oriented high strength fibers, or a large number of small objects in a matrix along with parallel oriented high strength fibers. A method for production of such a layered device is also taught. The material may be used in body armor including vests and helmets as well as applied to construction of shields and armored vehicles.

A reversed kinetic system for a shoe sole includes a fluid chamber containing fluid and a fluid expansion chamber in fluid communication with the fluid chamber, wherein the fluid chamber and fluid expansion chamber are separated by an elastic spring including at least one valve providing fluid communication. Each valve preferably comprises an inlet bore through the elastic spring and a yieldable diaphragm having a valve bore, whereby foot pressure on the fluid chamber causes fluid to dissipate through the valve bore into the fluid expansion chamber, wherein the dissipation of fluid through the valve bore causes friction and absorbs energy. Removing the foot pressure creates a negative pressure gradient in the fluid expansion chamber causing the yieldable diaphragm to release and allowing fluid to flow back into the fluid chamber through the inlet bore.

An improved mobility assistance apparatus for use by a person as a walking aid, e.g. a cane, crutch, or walker, has a support capable of bearing vertical forces during use of the apparatus as a walking aid and a resilient device connected to a lower portion of the support for ground engagement.

Two coiled springs are monolithically formed with the device at an upper end thereof. A flexible elongated member is connected to a radially inner, free end of each of the coiled springs and extends about a return at a lower portion of the device for resiliently expanding the coiled springs to store energy with force loading of the apparatus during use and to release stored energy during force unloading to generate propulsive force to aid mobility. The dorsiflexion moment of the resilient device is an order of magnitude greater than a plantarflexion moment thereof to mimic human ankle joint function.
