Abstract: An elongate beam has a mounting end and a projecting end, with a pulley mounted to the projecting end. A length-adjustable belt is mounted to the mounting end of the beam for securing the mounting end of the beam to an upright, such as a tree. A V-shaped brace assembly has a narrow supporting end pivotingly attached to the beam intermediate the beam ends, and a broad base end. The brace assembly includes a pair of legs which form the V-shape. The legs have spaced-apart base ends for positioning adjacent to an upright. A brace plate extends between the base ends of the legs and forms a recess facing away from the supporting end of the brace assembly for receiving uprights of different sizes.

Filed: 1999-12-09
Granted: 2003-06-10
Abstract: A punching, stamping rivet has a frustrum-shaped rivet head and a shank with a shank groove following thereafter. In order to create a riveted joint between two sheets, the sheets are punched through by the shank.      A groove is subsequently stamped around the shank end in the lower sheet, thus pressing material of the lower sheet into the groove. In order to increase the strength of the riveted joint, the shank groove is concavely constructed, whereby the section of the groove, which section is adjacent the rivet head, extends at an angle with respect to the shank axis, which angle is less than an angle at which the section adjacent the shank end extends with respect to the shank axis.

Title: Bioresorbable compositions of carboxypolysaccharide polyether intermacromolecular complexes and methods for their use in reducing surgical adhesions
Inventor: SCHWARTZ HERBERT E
IPC: C08J5/18
Filed: 1998-05-28
Granted: 2008-10-14
Abstract: The present invention relates to improved methods for making and using bioadhesive, bioresorbable, antiadhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides and polyethers, and to the resulting compositions. The polymers are associated with each other, and are then either dried or are used as fluids. Bioresorbable, bioadhesive, antiadhesion compositions are useful in surgery to prevent the formation of post-surgical adhesions. The compositions are designed to break down in-vivo, and thus be removed from the body. Membranes are inserted during surgery either dry or optionally after conditioning in aqueous solutions. The antiadhesion, bioadhesive, bioresorptive, antithrombogenic and physical properties of such membranes can be varied as needed by carefully adjusting the pH of the polymer casting solutions, polysaccharide composition, the polyether composition, or by conditioning the membranes prior to surgical use. Bi- or multi-layered membranes can be made and used to provide further control over the physical and biological properties of antiadhesion membranes. Antiadhesion compositions may also be used to deliver drugs to the surgical site and release them locally.

Granted: 2009-12-22
Abstract: A tridimensional map of the probability of functional brain conditions is obtained from the electric and/or magnetic signals (EEG/MEG) measured at the surface of the scalp. To this effect, statistical descriptive parameters of the EEG/MEG are measured and a map of its cerebral distribution is calculated.    The map is the reverse solution of EEG/MEG  based on: a) the restriction of the solution to structures with high probability to generate an electric activity by using a Cerebral Atlas and c) the solution has a predetermined uncertainty. The probability that said map or a subassembly of said map belongs to a template group is determined. To achieve said determination, the spatial correlation of the map as well as the dependency of experimental covariables are modelled. The resulting probabilities are coded in a pseudo-color scale and they are superposed on a Cerebral Atlas for their interactive tridimensional display. The Cerebral Atlas which are used in the solution of the reverse problem and for their display may be individual neuroimages, probabilistic Atlas or plastic deformation of a probabilistic Atlas with respect to the morphology of an individual.  Said methodology has been called quantitative electromagnetic encephalographic tomographic analysis (qEEG-T).
