Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Abstract: A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.

Abstract: A method of improving the performance of a powder dusting tip delivering powdered diatomaceous earth powder minimizing clogging in powder bulb duster tips through the use of tips with a more free flowing configuration and different spray patterns than the standard tip assembly and a flexible one piece powder dusting tube, which is attached to the tips which connects to reservoir of powder type insect repellents such as diatomaceous earth pesticides, boric acid pesticides, sevin based insecticides, deltamethrin based insecticides, and permethrin based insecticides as well as other powdered insecticides through threaded connections, made from flexible rubber tubing supported by memory wire that allows the powder duster tip to be positioned for hard to reach areas.

Abstract: The present disclosure is a toy that has hexagonal rings with letters on each hexagonal side that can be rotated to spell words that are present on cards that the users views, the hexagonal rings are removable and replaceable on a lift bar that fits into opening the vertical supports, to facilitate the rotating of the letters the inner hexagonal ring is offset from the letters on the outer ring so the letters fall into place, the variety of words that can be spelled are increased with sets of three hexagonal rings, each with their individual colors for their letters, and three sets of cards with words to spell, each with a color corresponding to the color of one of the set of hexagonal rings.
