Abstract: A method of treating a hoof of an ungulate animal. The method comprises coating one or both of (i) at least a portion of a bottom surface of the hoof or (ii) at least a portion of a block surface with a curable polymer and allowing the polymer to cure for a period of time. The polymer is cured within 60 seconds or less of the coating and the cured polymer has a Shore D hardness of about 10 to about 50. The curable polymer is provided as a two component system. The first component is a reaction product of (a) comprises 4-4?-diphenylmethane-diisocyanate, castor oil, isocyanatopropyltriethoxysilane, and glycidoxypropyltrimethoxysilane, and wherein (b) comprises dicyclohexylmethane-4,4-diisocyanate, polyether polyol, 4,4?-diphenylmethane-diisocyanate (MDI), and triethoxy(3-isocyanatopropyle)silane. The second component comprises polyoxypropylene oxide ether polyol, diol (2000 MW), polyxoypropylene oxide ether polyol, triol (450 MW), tetrahydroxypropylethylendiamine, metaxylenediamine, and organobismuth catalyst.

Abstract: An improved sealable pouch has an interior volume for receiving products for sterilization and an integral, foldable flap sealable to the pouch to provide a fully enclosed interior volume. Included on one or more portions of the pouch are indicia, preferably at least a first and second spaced apart indicia, to aid in proper folding of the flap. The indicia provide alignment means so that when the flap is properly folded to provide a leak proof seal, a predetermined portion of the indicia is covered by the flap. An improper seal can be visually determined to exist if all of the indicia or none of the indicia is visible after the seal is made. A proper seal is evidenced by only a portion of the first and second indicia being covered by the flap.

Abstract: A retraction cord for retracting gingival tissue is pre-impregnated with a chemical agent for chemically retracting gingival tissue and/or a hemostatic agent for arresting bleeding. A wetting agent is further applied to the cord to ensure product efficacy and shelf stability. The retracting agent may be an astringent water soluble organic salt such as aluminum potassium sulfate, aluminum sulfate, aluminum chloride, or ferric sulfate-or an inorganic salt of organic vascoconstrictors such as epinephrine, pseudoephedrine, or VISINE. The wetting agent is preferably a non-ionic surface active surfactant such as SILWET L-7607 at a concentration of 0.05% by volume.

Abstract: An ultrasound system is described which can be turned off quickly by an operator command or in response to an interruption of a.c. power to the system. When a.c. power is cut off, the system switches to battery backup while a processor executes an orderly shutdown sequence. The system can completely shut down, or the state of the system can be minimally preserved by battery backup in either volatile or nonvolatile memory so that the system can restart without having to sequence through an entire bootup procedure. This enables the system to remain active even when the ultrasound system is unplugged and being moved.

Abstract: An ultrasound system is described which exhibits reduced power consumption and improved reliability. When the ultrasound system is idle for a period of time it automatically invokes a sequence of energy-saving procedures, including readying the system for use at a predetermined time. The use of periodically invoked low power states, even if only for seconds at a time, will over the long term save energy including the cost of air conditioning the site of the ultrasound system. Such low power states also reduce the heat dissipation and exposure of components to heat, one of the major causes of component failure. Thus an embodiment of the present invention can improve ultrasound system reliability and long term effectiveness and cost.

Abstract: An ultrasound system is described which can be turned off quickly and restarted to be ready for scanning in a matter of seconds. This is accomplished by allowing a processor and/or memory within the system to remain active even when the system is “turned off.” When the system is turned off the state of the system is minimally preserved in either volatile or nonvolatile memory so that the system can quickly restart without having to sequence through an entire bootup procedure.

Abstract: An ultrasound system is described which will automatically turn on at predetermined times and condition itself for a specific scanning procedure. The system can also respond to remote queries even when not in service. Such an ultrasound system can be turned off at night, respond to external queries during the night, and be ready for use at a desired time the next day, without operator intervention, thereby conserving energy while maintaining efficiency.
