Abstract: Exemplary embodiments are directed to methods and systems for controlling fluid parameters within a detector. A first and second fluid pump manager control the flow of a first and second fluid to one or more heating/cooling devices, and a mixer receives and mixes the first and second fluids. An optical detector flow cell receives the fluid mixture from the mixer, and a pressure regulator controls the pressure at the optical detector flow cell. Thus, the composition, temperature, and pressure of a fluid mixture entering an optical detector flow cell can be controlled in real time.

Abstract: The invention provides differential refractive index detectors and methods for the use of differential refractive index detectors. In an exemplary embodiment, a differential refractive index detector includes a flow cell body having a proximal end, a distal end, and a flow axis extending between the proximal and the distal end. The flow cell body includes a first chamber and a second chamber and the fluid conduits coupled to the flow cell body can be tapered to reduce dispersion.

Abstract: The present invention is directed to devices and methods for performing photoreactions of photo-reacting compounds in solution. The invention features a vessel defining a chamber and a light source. The chamber has a chamber volume, a first window, an inlet and an outlet. The inlet is placed in fluid communication with a source of photo-reacting compounds in solution. The first window is transparent to light transmission and is placed in optical communication with a light source to receive photons. The chamber receives a solution of one or more photo-reactive compounds over time to define a dwell time. The device further includes a light source, in optical communication with the first window, for emitting photons which photons are received by the first window and transmitted into the chamber.

Abstract: Embodiments of the present invention are directed to devices and methods for performing photoreactions of photo-reacting compounds in solution. The invention features a vessel and a light source. The vessel has at least one wall defining a chamber. The chamber, for performing photoreactions, has a chamber volume, a first window, an inlet and an outlet. The inlet and outlet are in fluid communication with a source of photo-reacting compounds in solution. The first window is transparent to light transmission and is placed in optical communication with a light source to receive photons. The chamber is for receiving a solution over time to define a dwell time. The solution potentially has one or more photo-reactive compounds having a concentration. The device further comprises a light source, in optical communication with the first window, for emitting photons which photons are received by the first window and transmitted into the chamber.

Abstract: A biometric device comprising a scanner for reading a user's fingerprint. There can be at least one communication device in communication with the scanner. There can also be a control unit in communication with this scanner, this control unit can be for receiving biometric information from the scanner in the form of for example, a fingerprint. This control unit can be for controlling a remote device. There can also be a remote keypad, which can selectively communicate with said scanner, wherein this remote keypad can be used to adjust controls in the control unit to perform at least one of the following functions: selectively add a user, selectively delete a user or to review a list of users enrolled. The keypad can be in the form of a non-powered keypad or in the form of a cell phone, or PDA.

Abstract: A method and system of testing tubular member for contaminates. A testing prod may be used to collect particles from within the tubular member. A testing agent may be used to indicate whether the tubular member is contaminated as a function of the collected particles.

Abstract: A standalone, self-contained device for accessing and preventing unauthorized access to a home or dwelling using biometrics technology. The device improves upon traditional security access methods such as garage door openers, door locks, and alarm systems, by eliminating the need for physical keys and passwords. An individual's unique biometrics characteristics are captured and stored within the device through a secure administrative process which is used to identify authorized users. The correct identification of an individual results in authorized access controlled by the device.

Abstract: A method and system to represent surface temperatures. The method and system represent a surface temperature experienced by a medical device during a washing cycle in a medical washing machine. A temperature strip is positioned proximate a surface of the medical device to represent the surface temperature experienced by the medical device during the washing cycle in the medical washing machine.

Abstract: The present invention is directed to a sterilization tray assembly for sterilizing medical instruments. The sterilization tray preferably includes a base tray and a cover. Also, a secondary tray may be mounted within the base tray. These components ideally include ventilation apertures to allow steam or vapor to pass through the sterilization tray assembly to effect sterilization of medical instruments stored therein. The components of the sterilization tray assembly preferably are made of a mineral filled polypropylene and most preferably is a homopolymer which is filled with calcium carbonate, 40% by weight. This material exhibits good heat deflection characteristics at high temperature while being relative inert to absorption of H.sub.2 O.sub.2 vapor.
