摘要： A method and apparatus for sensing different levels of liquids in their respective containers in a liquid-consuming and/or producing instrument system. According to a preferred embodiment, an elongated liquid-sensing probe having axially spaced electrodes adapted to sense liquid at multiple levels is arranged in each container of liquid. A controller, e.g. a suitably programmed microprocessor, operates to selectively poll different pairs of electrodes carried by the probe to determine whether or not the polled electrode pairs are immersed in the contained liquid. Preferably, the polling circuit comprises an electronically-controlled resistor that serves to normalize the level-sensing output signal for liquids of different bulk resistivity.

摘要： A liquid transfer system for transferring liquid from a plurality of containers to a plurality of destinations comprises a plurality of inlet valves. Each inlet valve is operable between an open position allowing liquid from a container to be drawn into the system and a closed position blocking liquid from a container from being drawn into the system. Liquid drawn from each of the liquid containers is delivered to a buffer chamber designed to degas the liquid in the buffer chamber. The buffer chamber leads to a vented feeder chamber that is also adapted to retain a volume of liquid. A chamber connection valve is provided between the buffer chamber and the feeder chamber to allow or block the flow of liquid between the buffer chamber and the feeder chamber. The feeder chamber is connected to a plurality of distribution valves operable to deliver liquid to a plurality of destinations.

摘要： Method and apparatus for controlling the temperature of one or more reaction vessels in a bio-chemical analyzer comprises a heat-exchange block, preferably made of cast aluminum or the like, and a thermoelectric device for heating or cooling the block to within a desired temperature range. The heat-transfer block cradles one or more reaction vessels in a thermal energy-transferring relationship, and further supports, in a thermal energy-transferring relationship, one or more fluid conduits serving to transmit a liquid or gas to the interior of the reaction vessels. Preferably, the heat-transfer block is cast from aluminum, and the fluid conduits are disposed inside the casting. By supporting the reaction vessel(s) and fluid conduit(s) in a common block, a single thermoelectric device and controller can be used to simultaneously control the respective temperatures of multiple fluid reagents and/or gases, as well as one or more reaction vessels, thereby reducing the power requirements of the thermal control system.

摘要： A liquid aspiration device comprises an aspiration tube that slideably engages an opening in a cap such that a head on the end of the aspiration tube is moveable with respect to the opening in the cap. A tube cover is positioned between the opening in the cap and the head of the tube. The tube cover is operable to collapse into the cap when the head is moved into the cap. When the head and the tube cover are moved into the cap they are shielded from potential contamination that may occur when the aspiration device is moved from one container to the next. A lock is positioned in the cap. The lock is operable to move between an engaged position where the head may be retained within the cap and a disengaged position where the head is free to pass into or out of the cap.

摘要： Apparatus and method for aspirating liquid from a container, e.g., a test tube or other vessel, includes apparatus for sensing that an aspiration probe tip is contacting the inside bottom wall of the container, whereby a maximum volume of liquid can be aspirated from the container. According to the invention, an encoder is mounted on the driven member of a motor (e.g., on a rotatably-driven drive shaft or a nut of a stepper or D.C. motor, or on a linearly-driven shaft of a linear actuator) used to rectilinearly advance the probe tip into the container. Such encoder produces a series of pulses indicating the speed and/or linear position of the probe tip. A motor controller responds to a predetermined change in pattern of pulses from the encoder indicating that movement of the probe tip has been resisted by the vessel bottom, whereby further movement of the driven member and of the probe connected thereto is arrested, and the probe tip remains in contact with the vessel bottom.

摘要： Provided is a bio-sensor system which utilizes radio frequency identification technology and which includes a remote transponder in wireless communication with an implantable passively-powered on-chip transponder. The bio-sensor system is specifically adapted to provide a substantially stable and precise sensor reference voltage to a sensor assembly that is included with the on-chip transponder. The remote transponder is also configured to remotely receive data representative of a physiological parameter of the patient as well as identification data and may enable readout of one or more of the physiological parameters that are measured, processed and transmitted by the on-chip transponder upon request by the remote transponder. The precision and stability of the sensor reference voltage is enhanced by the specific circuit architecture of the glucose sensor to allow for relatively accurate measurement of the physiological parameter such as measurement of glucose concentration by a glucose sensor without the use of a microprocessor.

摘要： Apparatus for aspirating liquid from a container, e.g., a test tube, having a puncturable stopper includes a pair of stepper motors that share a common linear actuator or drive member. One motor operates to axially advance the linear drive member (preferably a lead screw) to a position in which it serves to position a rigidly connected tube-detector/stripper member in engagement with the top of a stopper on a tube. Thereafter, the second motor operates to move along the surface of the same drive member to advance an aspiration probe through the engaged stopper and into a liquid aspirating position within the tube. Preferably, a linear guide rail, slidably-mounted on a frame that supports the liquid-aspirating apparatus, serves to guide both the movement of the aspiration probe and the linear drive member. As a result of the shared components, the apparatus is highly precise and reliable.
