Abstract: A cardiac assist device containing a device for connecting the cardiac assist device to a heart, for furnishing electrical impulses from the cardiac assist device to the heart, for ceasing the furnishing of electrical impulses to the heart, for receiving pulsed radio frequency fields, for transmitting and receiving optical signals, and for protecting the heart and the cardiac assist device from currents induced by the pulsed radio frequency fields. The cardiac assist device contains a control circuit comprised of a parallel resonant frequency circuit.

Abstract: A thermal printing assembly comprised of a first flexible section and a second flexible section joined to such first flexible section. The first section of such assembly is a thermally sensitive media that contains either a thermal transfer ribbon or a direct thermal sensitive substrate (such as thermal paper); the thermally sensitive media is adapted to change its concentration of ink upon the application of heat. The second section of such assembly is a flexible support with two sides, at least one of which has a smoothness of less than 50 Sheffield Units and contains particles with a Knoop hardness of less than about 800.

Abstract: A ceramic decal assembly containing a ceramic substrate, a layer of adhesive contiguous with the substrate, and a ceramic decal contiguous with the layer of adhesive.

Abstract: A ribbon cassette containing a supply core, a web located on the supply core, a storage core, a device for increasing the tension on the web as it passes from said supply core to said storage core to produce a tensioned web, a drive roller contiguous with the web, and a nip roller contiguous with the web. The said tensioned web is passed in a first rotary direction around a portion of the drive roller, and then it is passed in a second rotary direction around a portion of the nip roller, and then it is passed in a in rotary direction identical to the first rotary direction around a portion of the storage core. A nip is formed between the nip roller, the web, and the drive roller such that either the nip roller or the drive roller is compressed by at least about 0.001 percent.
