Title: Portable self-contained cooler/freezer for use on airplanes, common carrier unrefrigerated trucks
Inventor: SAIA LOUIS P III
IPC: F25D3/10
Filed: 1992-06-29
Abstract: A transportable container for carrying refrigerated products in frozen or refrigerated temperatures includes a structural container having an insulated outer shell with an access doorway.      The upper portion of the container includes a transverse perforated baffle and positioned above the baffle are a pair of spaced apart canisters containing liquid refrigerant. A gas or liquid feeder tube penetrates each bottle and communicates with an on/off valve. A feeder tube can draw liquid to dispense for cooling, or it can release gas and pressure within the canister to boil the CO2. When CO2 reaches its boiling point, the canister, its bracket, and the cold plate reach very cold temperatures to cool the cargo area. The gas is released through copper tubing over the cold plate to act as method for convection.

Patent CA-2187470-A1 (CA)
Inventor: MARIMONT DAVID H
IPC: G06T11/00
Filed: 1996-10-09
Abstract: A data structure representation of an image called an image structure map (ISM) accurately and explicitly represents the geometry, topology and signal properties of regions in an original image and allows for efficient and accurate spatial indexing of the image and those regions.      The ISM may serve as the basis for an image interaction system in which a user interacts with a rendered view of an original image that is produced from the ISM data structure. The rendered view of the original image represents the geometry and topology of the original image as represented in the ISM. The user interacts with the rendered view to make alterations to, or to query, the structures in the ISM. The user may also modify the ISM by interacting directly with a displayed view of the original image. The user may further invoke automatic operations to be performed using the original image data structure that produce image region data, such as signal property descriptors and boundary data, that may be used to modify the ISM. An image interaction system implemented in this manner takes full advantage of automatic computation methods to capture the geometric and topological properties of an image while permitting a user to employ human perceptual skills to augment the automatic operations.     An illustrated implementation of the system uses an ISM having the form of a vertical cell decomposition that is mathematically robust, topologically consistent with the original image and is able to be modified dynamically that is, without recomputing the entire ISM when a change is made.
