Abstract: A frequency selective transient voltage protector (FSTVP) circuit that may be used in connection with a communication line over which POTS and DSL service may be simultaneously provided. The FSTVP circuit attenuates high frequency transient voltages that exceed a predetermined voltage level, while permitting low frequency, generally high voltage signals (e.g., ring signals) and high frequency, low voltage signals (e.g., DSL signals) to pass with little or no attenuation. The FSTVP circuit comprises a frequency selective network (that comprises a frequency discriminator and a voltage discriminator) connected to an overvoltage protection device that shunts any high frequency transient voltages thus protecting devices connected downstream along the communications line from damage. The frequency selective network is tuned to gate the overvoltage protection device when the frequency and voltage of a signal present on the communication line exceed predetermined values.

Abstract: A sample testing device has a buffer container that can hold buffer fluid, a filter with a securement for holding a test strip, the test strip, a test strip container having a receptacle to accommodate the filter, so that when the filter is held therein the test strip is disposed in the receptacle, and a sample collector for holding a sample. The sample collector receives the buffer container, and the sample collector has a piercing member which, when the buffer container is placed in the sample collector, pierces the buffer container. Buffer fluid in the buffer container then contacts the sample. As buffer fluid flows through the sample collector, the buffer fluid that has contacted the sample passes through the filter to the test strip.

Abstract: A housing for a shaving razor with razor blade(s) immersed in oil or another liquid. The primary structure permits a minimal quantity of oil or other liquid to submerge the razor blade with the razor handle upright. It also may feature a catch extension on the back wall to aid oil drainage from the submersed end. The second structure is a frontally mounted lid with razor handle positioned for easy access. To secure the housing in the desired position, a “hook and loop” type attachment device can be provided to allow removal for cleaning. In another embodiment, an insert may be disposed within the housing, next to the back wall. The insert has a razor handle receiving portion and a razor blade catch extension. In another embodiment, the housing may be formed in a free-standing configuration so that it may be rested upon a countertop or table. This embodiment may be formed with a container holding portion having an oil container recess.

Abstract: A structure and a method of manufacturing the organic electroluminescent (EL) elements, patterns of icons on the display panel of organic EL elements are formed. Initially, ramparts are formed on a continuous surface of a transparent and conductive film, i.e. an indium-tin oxide (ITO) film, and ramparts determine patterns of icons, then organic function layers and electrodes are formed. Processes are compatible to a conventional method of manufacturing an array type display panel, to improve disadvantages of dividing processes of array type display panels and organic EL elements into two portions.
