Abstract: Certain exemplary embodiments can provide a system comprising a substantially transparent radiation shield, which comprises transparent ammonium metatungstate. The transparent ammonium metatungstate can have a density of greater than 1.5 gram/(cubic centimeter). The substantially transparent radiation shield can be installed on tanks and/or pressure vessels, used as a transparent radiation shield in medical shielding/devices, used as windows in glove boxes, and any application where effective radiation shielding is needed with transparency. The substantially transparent radiation shield can be used in one or more articles worn by a human.

Abstract: A battery system includes a first cell that is electrically connected to a second cell via a push-on clip. The clip is an electrically conductive plate that includes a first cutout that is configured to receive and snap onto a first terminal of the first cell, and a second cutout that is configured to receive and snap onto a second terminal of the second cell. The first and second cutouts are irregularly shaped and formed in the peripheral edge of the clip. The first and second terminals each have a widened distal end, and an interference fit is formed between the clip cutouts and the corresponding widened distal end, whereby a secure electrical connection between the terminals and the clip is provided.

Abstract: Certain exemplary embodiments can provide a system comprising a housing having a first end and a second end, a first set of light emitting diodes, and a channel coupled to the set of light emitting diodes. The channel can comprise a surface to mount the set of light emitting diodes.

Abstract: A high output, powered air purifying respirator that includes an anti-contamination suit, a filter for filtering particulates from the air, a high powered blower for delivering a cool flow of air to the body, and a stabilization mechanism. The stabilization mechanism is configurable in either head mounted or back mounted modules as desired by a worker. The head mounted configuration facilitates stream lined mobility and includes a head mounted suspension system with a circular rail and roller bearing halo around the worker's head for stabilizing the blower/filter and allowing for rotation of the worker's head inside the halo. The invention also includes additional modules, also configurable by the user, such as personal hydration and independent camera and dosimeter support.

Abstract: Inhibitors of protein:farnesyl transferase enzyme are described, as well as methods for the preparation and pharmaceutical compositions of the same, which are useful in controlling tissue proliferative diseases, including cancer and restenosis.
