Abstract: A cap adapted to cover an end of a cask for maturation of a spirit, comprises a body having an outer plate and a flange extending from the outer plate, and an inner plate spaced from the outer plate. The inner plate lies between the outer plate and the end of the cask when the cap is in place on the end of the cask. A layered or ridged spacer can separate the plates, and can permit fluid transfer in the space between the plates. The inner plate can be resistant to vapor transfer, and can be pressed against the outer surface of the end of the cask when the cap is in place on the end of the cask, and leaves an annular area of the end of the cask uncovered.

Abstract: An electronic wallet which is biometrically secured stores credit card and other information. A biometric sensor prevents the electronic wallet from being used by the user who does not have permission to use the wallet. A rewriteable card is inserted into a slot of the wallet in order to have credit card information placed on the card. After the card is used the information is erased from the card when it is placed back in the slot in the electronic wallet.

Abstract: An object detection system utilizing one or more thin, planar structured light patterns projected into a volume of interest, along with digital processing hardware and one or more electronic imagers looking into the volume of interest. Triangulation is used to determine the intersection of the structured light pattern with objects in the volume of interest. Applications include navigation and obstacle avoidance systems for autonomous vehicles (including agricultural vehicles and domestic robots), security systems, and pet training systems.
