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: The disclosed embodiments include a protective housing for a fragile article for containing fluid medicament.

Abstract: An improved golf ball marker comprises a cap having a generally hemispherical hollow, the hollow having approximately the same dimensions as one half of a standard golf ball, the cap having first and second linear slits forming a “T” shaped slit configuration for marking a golf ball inserted in the hollow with a “T” mark comprising a seam indicator line and a club alignment line. The golf ball is positioned and oriented in the hollow of the cap such that the seam is aligned with the first linear slit for making the seam indicator line on the ball with a marker and the second linear slit is perpendicular to the seam for making the club alignment line on the ball.
