Abstract: The invention described in this disclosure involves a new composition of matter, amyloid beta-derived dementing ligands (ADDL's). ADDLs consist of amyloid ? peptide assembled into soluble globular non-fibrillar oligomeric structures that are capable of activating specific cellular processes. The invention further encompasses methods for assaying the formation, presence, receptor protein binding and cellular activities of ADDLs. The invention further encompasses assay methods and inhibitor molecules for cellular signaling molecules activated by ADDLs. Also described are molecules that block proteins that promote the formation of ADDLs.

Abstract: Embodiments of the present invention provide mechanisms and methods for measuring shooting performance. These mechanisms and methods for measuring shooting performance make it possible for coaches and players to obtain information they need to measure levels of play, improve and maintain skills, select players to meet game situations and team requirements, and make decisions on player roles.

Abstract: An imaging apparatus includes a printing mechanism having a media path. A print media source is provided for supplying a sheet of print media to the printing mechanism. A drive unit is provided, with a drive shaft coupled to the drive unit. A media sensor device is mounted to the drive shaft, wherein as the drive shaft is rotated in a first direction the media sensor device is moved from a first position that is out of the media path to a second position that is in the media path for sensing the sheet of print media. As the drive shaft is rotated in a second direction opposite to the first direction the media sensor device is moved from the second position that is in the media path for sensing the sheet of print media to the first position that is out of the media path.

Abstract: Printer (1) feeds paper or other media sheets (5) to pinch rollers (9a, 9b), which further feed the sheets into an imaging station (7). Pressure rollers (9b) are held by plate 22 which is biased by a spring (33) and pivots on extensions (37a, 37) to moves pressure rollers (9b) into nip relationship with nip roller (9a). To evenly distribute the forces across pressure rollers (9b), plate 22 is weakened by depressed lines (27a, 27b) located between the spring and the pressure rollers (9b).

Abstract: Printer (1) has a pivotally mounted autocompensating system (19) mounted at an intermediate position in paper guide (17). That system (19) is driven by a motor (40) through a slip drive (70, 72, 74). The motor also drives paper feed system (15). When the motor turns in a direction to feed by system (15), the intermediate system is moved away from the paper guide. When a sheet reaches a position to be fed by the intermediate system, the motor is reversed, and the intermediate system pivots against the paper for moving it further through the paper guide.

Abstract: Per-6-substituted-per-6-deoxy-cyclodextrins and compositions containing the same are disclosed. The compounds and compositions inhibit the formation and/or activity of soluble ?-amyloid-peptide derived oligomers, and can be used to treat diseases and conditions wherein such inhibition is beneficial, for example, Alzheimer's disease.

Abstract: An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.

Abstract: A conductive releasable adhesive and method of making same for electrostatic discharge controlled surfaces in which a multiplicity of interlacing electrically conductive fibers is suspended in a releasable adhesional substance forming a conductive matrix throughout the volume of the adhesional substance for facilitating dissipation of electrical charges.

Abstract: A one-piece plastic pin fastener is utilized to secure the assembled position of a plate-like member, such as an electronic circuit board in an electrical receptacle equipped to provide ground fault protection. The headed pin fastener, having a T-shaped shank consisting of a flexible cross-beam and a transverse loading beam, is press-fitted in an undersized bore. The fastener securely holds the circuit board in place, and yet can be removed for servicing and replacement of the electronics.

Abstract: An organic friction pad having iron powder particles added thereto to provide thermal stability when used with a copper rotor to maintain a substantially uniform coefficient of friction up to 550.degree. F.

Abstract: An electronic module for use in ground fault circuit interrupting devices comprises an improved shell design structurally adapted for ease of assembly therein of the electronics and magnetics. The electronics, carried on a printed circuit board, is positionally mounted and retained in one shell compartment by integrally formed latching means. The magnetics are positionally mounted in other shell compartments and locked in place by the insertion therethrough of single-turn transformer winding elements. Potting of the electronics and magnetics thus becomes unnecessary.
