Abstract: An adaptor device for retrofitting in a filter housing is disclosed. The adaptor device allows the filter to be retrofitted with a plurality of filter elements, thereby improving its filtering efficiency.

Abstract: An audio device with a body configured to be worn on or abutting an outer ear of a user, wherein the body is configured to contact at least one of the outer ear and the portion of the head that abuts the outer ear, at two separate spaced contact locations, and wherein the body is compliant at a body portion that defines one of the contact locations. The device also has an acoustic module carried by the body and configured to locate a sound-emitting opening anteriorly of and proximate the user's ear canal opening when the body is worn on or abutting the ear of the user.

Abstract: The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

Abstract: An adaptor device for retrofitting in a pool filter housing is disclosed, where the pool filter housing has a conventional cylindrical concentric filter. The adaptor device allows the pool filter to be retrofitted with a plurality of filter elements, thereby improving its filtering efficiency.

Abstract: A curtain of a flexible fabric is provided that is deployable to create a physical and visual barrier between an employee and a person perpetuating a crime such as a robbery or assault. The barrier can be in the form of a curtain that is electrified with an extreme high voltage, similar to a stun gun, and which prevents the assailant from approaching an employee or a restricted area. The curtain can be mounted in any area where it is beneficial to limit site and access of a trespasser or an assailant, such as between a cashier at a convenience store and the store's open retail area. The curtain can also be used to create temporary safe rooms or deployed within hallways of a restricted area to limit movement of an intruder.

Abstract: A hydraulic shock absorber comprising a piston and hollow piston rod slidable within a cylinder, and a plug assembly including a spool valve for metering fluid into the piston rod when an impact force forces the piston into the cylinder. A coil spring normally biases the valve spool to block fluid passage. An adjustment rod is threaded into the plug assembly to form a seat for the valve spring, and extends through the hollow piston rod. The adjustment rod may be rotated from externally of the piston rod for varying spring bias on the valve spool. A closed cell sponge is disposed within the plug-remote end of the piston rod.
