Abstract: An alignment device for a weapon that generates a simulation beam and an alignment beam used to align the simulation beam with the weapon's sight. The device can be secured to the weapon during the alignment process, after which it can be removed. The device includes a housing that can be mounted on the weapon so that its optical receiving port intersects both the optical alignment beam generated by the optical transmitter and the sighting axis of the weapon's sight. The optical receiving port includes an optical arrangement for receiving the alignment beam and focusing it on a projection screen located inside the housing. An image of the alignment beam on the projection screen can be viewed through the sight. The alignment beam is parallel to the simulation beam. Thus, by centering the alignment beam in the sight, the alignment beam, and hence the simulation beam, will be properly aligned.

Abstract: An alignment device is provided for a weapon that generates a simulation beam and an alignment beam that is used to properly align the simulation beam with the weapon's sight. The device can be secured to the weapon during the alignment process, after which it can be removed. The device includes a housing that can be mounted on the weapon so that its optical receiving port intersects both the optical alignment beam generated by the optical transmitter and the sighting axis of the weapon's sight. The optical receiving port includes an optical arrangement for receiving the alignment beam and focusing it on a projection screen located inside the housing. An image of the alignment beam on the projection screen can be viewed through the sight by a user. The alignment beam is parallel to the simulation beam. Thus, by centering the alignment beam in the sight, the alignment beam, and hence the simulation beam, will be properly aligned.

Abstract: An automated sprayer for spraying walls of a shower or bathing enclosure with a liquid cleanser. A spray head rotates on an essentially vertical axis. Its outlet nozzle pivots on an essentially horizontal axis (but not otherwise) to adjust the vertical angle of the spray, thereby rendering the device adjustable for different size enclosures, and for treating problem stains.

Abstract: An apparatus for communicating simulation data is disclosed. The apparatus includes an assembly for mounting the apparatus on an edifice. The apparatus further includes a receiver for receiving simulation data from a plurality of players within a specified area of the edifice and for receiving simulation data from a central controller. The apparatus further includes a transmitter for transmitting simulation data to the plurality of players and to the central controller, wherein simulation data is transmitted to the central controller only when a simulation event occurs. In one alternative, the apparatus further includes an infrared camera for capturing video and still images of simulation events. In another alternative, the apparatus includes an infrared radiator for producing infrared light for illuminating video and still images captured by the infrared camera.

Abstract: There are disclosed colloids containing polymer-modified core-shell particle carrier. The described colloids containing core-shell nanoparticulate carrier particles wherein the shell contains a polymer having amine functionalities. The described carrier particles are stable under physiological conditions. The carriers can be bioconjugated with biological, pharmaceutical or diagnostic components.

Abstract: The present invention relates to a method of particle separation comprising preparing a suspension of particles containing at least one recognizable target particle in a suspending solution, labeling the target particle with a conjugate marker, wherein the conjugate marker comprises at least one recognition unit for the recognizable target particle and at least one peroxidase enzyme, contacting a gelatin surface with the suspending solution, adding developer to the suspending solution in contact with the gelatin surface and in the presence of phenol to attach the target particle to the gelatin surface, and washing the gelatin surface to remove unattached particles. The method may also include detecting the presence of the target particle on the gelatin surface as well as detaching and recovering the attached particles after removal of the non-target particles.

Abstract: A protein microarray element comprising: a) a support; b) a gelatin layer containing functional groups capable of binding biological probes; and interposed between the support and the gelatin layer and c) an adhesive interlayer layer capable of maintaining contact with the support and with the gelatin layer.
