Abstract: A disclosed player tracking unit utilizes a memory arranged to store a plurality of different communication protocols allowing the player tracking unit to communicate with a plurality of different types of gaming machines and a plurality of different types of player tracking servers. The player tracking unit may contain many different types of player tracking peripheral devices such as card readers, key pads, displays, bonus buttons and biometric input mechanisms. The peripheral devices contained in the player tracking unit may be accessible to the master gaming controller on a gaming machine and may be utilized by the master gaming controller for other gaming applications. The player tracking unit may be designed with a standard housing and standard device layout allowing the player tracking unit to fit in many different types of gaming machines with minimal modifications to the gaming machine or the player tracking unit.

Abstract: For sample picking on a cryosubstrate, on which multiple cryopreserved samples are each positioned at preselected sample positions, individual samples are selectively separated mechanically or thermally from the cryosubstrate and transferred to a target substrate.

Abstract: A device (10) for removal of gas bubbles and dissolves gasses from fluids delivered into a patient during medical procedures is disclosed. A housing (20) having a number of gas permeable hollow fibers (50) passing therethrough is provided. The infused fluid is introduced through the interior lumens of the hollow fibers (50), and entrained or dissolved gasses are drawn through the fiber walls to the outer or shell side of the fibers. A vacuum may be drawn on the housing through a vent (32) to enhance gas removal. A passage (70) is optionally provided through the device to allow a tool or other device to be passed therethrough.

Abstract: Liquid crystals compositions, i.e. cholesteric liquid crystals or various types of liquid crystal polymers designed to turn red at or above a specified temperature and remain red at or above that temperature and that are shaped in the outline of the word "HOT" (or for cooktop stoves of a ring surrounding the heating element that may be interrupted by such an outline) are embedded on the top surface of the heating element of stoves or on the window surface of wall ovens and toaster ovens so that they glow red and instantly alert anyone that the heat element of the stove or the window is too hot to touch. For use on electric stoves including small mobile electric stoves called hot plates, the device is an improved electric coil whose central recessed area contains liquid crystals. For use on smooth cooktop stoves, including small mobile cooktop stoves called warming trays, the liquid crystal display is embedded in a top surface of the smooth area of glass or metal that forms the heating element of the stove.
