Abstract: A device includes: a first portion configured to be grasped by the hand of the user, and a second portion defining a reservoir containing a control material, wherein the control material contains a target analyte in a known or predetermined concentration. A method of verifying the accuracy of an analyte monitoring device includes receiving a fluid sample, identifying the fluid sample as a control solution, and analyzing the fluid sample.

Abstract: A line circuit is described which provides isolated power to a subscriber telephone line in a manner that produces a constant power characteristic over the normal range of telephone line loop resistance. The isolated feed characteristic of the present invention simplifies protection against lightning and other transients. The constant power characteristic limits power dissipation under short loop, i.e. low resistance, or short circuit conditions yet allows enough current flow under short loop conditions to activate the voice level reducing varistor in the telephone sufficiently to prevent excessive loudness. This eliminates the need for additional circuits at the telephone central office for detecting short loops and for providing voice frequency (VF) level attenuation under such conditions.

Abstract: This invention comprises a tool for baiting of fishing hooks and lines. The tool has a handle with a pair of telescoping needles; the first needle is hollow and slidably receives the second needle. Both of the needles have end recesses for receiving the point of a fishing hook. The first, outer needle also has a distal notch for attachment of a leader or fishing line while the second, inner needle has a distal aperture through which a leader or fishing line can be threaded.The handle slidably receives the inner needle and has detents to lock the inner needle in its extended and retracted positions. The inner needle is used for application of bait to small hooks or to a leader, while the outer, larger diameter needle is used for the application of bait to large hooks or to leaders. Both needles can be used to apply bait to multiple-hook fishing hooks.

Abstract: Flexible pipe used to supply water to remotely located drilling rigs, typically made from a suitable synthetic resin such as polyethylene, is laid and retrieved from spools or reels mounted with a vehicle as the vehicle is moving. The vehicle may be a truck or a trailer drawn by a truck or tractor. Guiding structure is provided on the vehicle to facilitate loading and unloading of the pipe from the reels.
