Filed:

Jul 14, 1998

Appl. No.:

09/115328

Inventors:

Thomas Lindquist - Eden Prairie MN

Assignee:

Digital Biometrics, Inc. - Minnetonka MN

International Classification:

G06K 900

US Classification:

382100, 101493, 205582

Abstract:

A computer implemented gambling chip recognition system having the ability to capture an image of a stack of gambling chips and automatically processing the image to determine the number of chips within the stack and the value of each. The system processor determines the classification for each chip in a stack by way of processing performed in real time on the image of the stack of gambling chips. The system further includes the ability to communicate the information derived from the stack of gambling chips to a video monitor and the ability to communicate the information to a main database where information is being compiled and stored about an individual gambler.

Appl. No.:

11/200363

Inventors:

Thomas Lindquist - Eden Prairie MN, US
William Preska - Woodbury MN, US

International Classification:

G06K 9/40

US Classification:

382254000, 382128000

Abstract:

A method of and system for controlling image quality in a digital image printing system, such as a medical image printing system, is provided a digital medical image including a set of pixels, each of which has a pixel value, is acquired from a medical image source. A medical image printer prints the medical image on media to produce a medical image print. A device measures the density of at least a subset of the set of pixels on said medical image print to produce a measured density image. There is calculated for at least the subset of the set of pixels of the digital medical image a predicted density image. The measured density image and the predicted density image are compared to produce density corrections, if any; and any density corrections are used in printing subsequent digital medical images to improve image quality thereof.

International Classification:

US Classification:

220694, 73 405 R

Abstract:

In various embodiments, systems and methods are provided for constructing and testing of a barrier providing secondary containment for aboveground storage tanks. Concrete storage containers can be manufactured with primary steel tanks and spill containment formed using an airtight tank wrap. Concrete storage containers can be manufactured with a barrier providing secondary containment to meet or exceed most current codes and standards commonly required for the storage of petroleum, flammable, combustible and other hazardous liquids. Such storage containers can include one or more thermal barriers that provide enhanced resistance when subjected to liquid-pool/furnace fire tests. Additionally, a concrete exterior acts as a thermal mass reducing temperature variations. The concrete exterior further provides a non-corrosive, durable exterior having increased vehicle-impact and projectile-impact resistance. Due to the method of construction in some embodiments, concrete storage containers are provided which give thermal/vehicle impact/projectile resistance while also meeting expectations in weight and buoyancy criteria.

Abstract:

A storage vault includes an inner tank entombed within a concrete outer tank by first erecting a pair of sidewall forms on a base plate to create an open-top enclosure. The wall forms are securely clamped together. A layer of concrete is then poured onto the base plate and the inner tank is restrained by lowered onto the layer of concrete. Concrete is poured into the enclosure to entomb the inner tank while the bottom layer of concrete is still wet. The inner tank is a pair of reinforced hold-down bars extending over the top of the enclosure and having a pair of downwardly extending hold-down tubes which contact the top of the inner tank. Back hold-down bar is forced downwardly by a chain which passes over the hold-down bar and is fastened to the base plate. After the concrete has set sufficiently, the hold-down bars and tubes are removed and the holes created by the hold-down tubes are filled with concrete. After curing, the wall forms and base plate are removed from the vault created within the form assembly.
