Abstract: The present invention incorporates a silicon based isolation device into a portable computer. An additional silicon based isolation device is also incorporated into a docking station for a personal computer. Either or both of the isolation components may be programmable. The invention also teaches a silicon based isolation device for use with a modem. Again, the silicon based isolation devices may be programmable. An embodiment of the invention teaches a circuit (or other means) to detect docking of the computer in a docking station.

Abstract: A method and an apparatus for determining the thickness of a layer of a first liquid above an interface formed by the first liquid and the second liquid underlying the first liquid in a subterranean formation. The apparatus includes an elongated metal rod having a sharpened distal end. An electrode is provided adjacent the sharpened distal end to indicate when the interface formed by the two liquids has been reached. A lengthwise running elongated slot is provided in the outer surface of the body of the metal rod and contains an indicator strip. The indicator strip is adapted to undergo a color change upon contact with the first liquid. By measuring the length of the indicator strip which has undergone a color change, the thickness of the layer of the first liquid can be determined.

Abstract: A container for receiving and holding an object comprises generally parallel front and rear panels, generally parallel side panels, and a bottom panel, the edges of the front, rear and side panels being joined together and being joined with the bottom panel to form a generally bag-like container with an open top. The top edges of the front, rear and side panels are folded toward the bottom panel to form a reinforcing cuff proximate the open top of the container. A support member includes a first portion installed within the cuff and a second portion extending from the first portion out of the cuff and beyond the top of the container. The second support member portion includes an opening for receiving a supporting member for supporting the container in a hanging condition.
