Abstract: A body cool harness is disclosed. The body cool harness may have a body portion for overlaying the back region of a person, a first wrap-around portion, and at least one cooling device.

Abstract: A cooling assembly is disclosed. The assembly includes a substrate and one or more cooling devices. The cooling device includes water and a reactant (such as ammonium nitrate), which when mixed, result in an endothermic reaction. One type of cooling device has an impermeable bag and a selectively breakable bag inside. Another type of cooling device has an impermeable bag and a selectively breakable barrier, which divides the bag into two packages. In use, when the water and reactant are allowed to mix, the cooling device becomes cool. The cooled device absorbs heat from an injured person placed on the device, thereby minimizing inflammation that may occur from injuries sustained by the person. One type of substrate that is in keeping with the invention includes a body portion, a first wrap-around portion, a second wrap-around portion, and a hood. Another type of substrate that is in keeping with the invention includes a body portion, a first side cooling flap, a second side cooling flap, and a hood.

Abstract: A medical device embodied as a stretcher, body bag, or mattress is disclosed. The device includes water and a selectively breakable package. The selectively breakable package includes a chemical, such as ammonium nitrate, which when mixed with water will cause an endothermic reaction. In use, the package is broken in order to cause the water to cool. The cooled water absorbs heat from an injured person placed on the device, thereby minimizing inflammation that may occur from injuries sustained by the person.

Abstract: A method and a system of authorizing a transaction without using a man-made token is disclosed. In a method according to the invention, a biometric sample is registered, biometric information is provided, the biometric information is compared to the biometric sample, a determination is made as to whether the biometric information matches the biometric sample, and if a match is determined, then the transaction is authorized.

Abstract: Medical information systems and methods are disclosed. A database of pointers may be used to identify the location of medical information and a biometric may be required to obtain those pointers.

Abstract: The invention may be embodied as a customer reward system or a method of rewarding a customer. A reward system may have a database of enrolled biometric samples, a point-of-sale station having a biometric-sample receiver, and a comparator in communication with the database and the point-of-sale station. In a method according to the invention, an enrollment station is provided and a first biometric sample is received along with an enrollment request. The first biometric sample may be enrolled in a database to provide an enrolled biometric sample. A point-of-sale station may be provided, and a second biometric sample may be received along with a point-of-sale request. The enrolled biometric sample may be retrieved and compared to the second biometric sample, and then a determination may be made as to whether the enrolled biometric sample is equivalent to the second biometric sample.
