The disclosed sterilizer includes a humidity control system for controlling humidity. The sterilizer for sterilizing objects comprises a chamber for receiving objects to be sterilized and a humidity control system. The humidity control system comprises a water control system which can be connected to a water source for injecting a first quantity of water vapor into the chamber, a pressure sensor in fluid communication with the chamber for measuring pressure in the chamber, a humidity sensor in fluid communication, or in selective fluid communication, with the chamber for sensing a first humidity value (RH) of the first quantity of water vapor in the chamber; and a controller configured to inject a second quantity of water vapor into the chamber.

Sterilizer with a humidity control system

Systems and methods for controlling humidity. Methods can include providing a chamber configured to receive objects to be sterilized; injecting a first quantity of water into the chamber; determining a pressure rise and a pressure drop in the chamber resulting from the first injection; calculating an absorption ratio (AR) as the ratio of the pressure drop to the pressure rise; sensing the humidity of the chamber after the first injection to determine a first humidity value (RH); comparing the first humidity value to a pre-selected humidity value (RH) to determine a humidity error (RH), wherein RH=RH&#x2212;RH; and injecting a second quantity of water into the chamber, wherein the second quantity of water is calculated based on the absorption ratio (AR) and the humidity error (RH). Systems can perform the method; and the systems and methods can be employed in a sterilizer.

The present invention provides a display seal for a force-based sensor assembly that includes a flexible membrane having inner and outer surfaces, and first and second sides. The first side of the membrane is capable of being mounted to a housing of the assembly, such as a frame or bezel, and the second side of the membrane is capable of being mounted to a touch surface of a touch sensitive structure of the assembly. The seal, when mounted to the housing and the screen, is capable of creating a seal around the screen without passing extraneous forces to the transducers.

A laser imaging system for direct imaging with high optical power density a series of pixels forming an image on a media surface, The laser imaging system includes a laser light source, wherein the laser light source emits a laser beam representative of the image on the media surface. An optical path is defined between the laser light source and the media surface. A scanner is provided having a mirrored surface positioned along the optical path. An optical assembly is positioned along the optical path for shaping and focusing the laser beam at the media surface, including an F-Theta lens assembly positioned along the optical path between the scanner and the media surface. The F-Theta lens assembly includes a spheric lens, an aspheric lens and a toric lens, providing an increase in optical power density at the media surface.
