摘要： A shear valve obtaining selective fluidic communication between fluid ports formed in a first member and fluid ports formed in a second member comprises a first seal with means for providing a fluidic seal between aligned ports and which separates the first and second members to form a passage, and a second sealing means to obtain a fluidic seal between the first and second members and enclose the passage. A fluid port is provided to introduce wash solution into the passage formed between the first and second members and a drain port is provided to remove the wash solution introduced between the first and second members, so that a wash and purge operation may be performed to cleanse the sealing surfaces of the valve.

摘要： Plunger operated pipet operable to execute different lengths of plunger movement during successive fluid pickup and fluid discharge operations or strokes. A stop member is movable between first and second locations in the pipet body to halt plunger movement at two different positions. A drive spring for driving the stop member from one location to the other is energized by a manually operable arming element and is retained in one location against action of the drive spring during a first plunger stroke. A release mechanism responsive to plunger movement during the first stroke disables the retaining means allowing the drive spring to move the stop member to the second location at which position the plunger is halted during the succeeding discharge stroke. The arming element is actuated by and in response to positioning of a replaceable tip on the pipet body. The arming element exerts a force on the tip sufficient to expel the tip from the body unless the tip is properly seated on the body thus ensuring that the pipet is armed if the tip is properly seated. A signalling system is provided which signals the occurrence of the second or fluid dispensing stroke of plunger movement.

摘要： Apparatus for automatically and selectively supplying a blood sample or a wash/calibration solution to the entrance port of a flow cell which measures characteristics of the sample such as pH, pCO.sub.2 and pO.sub.2. A sample filled syringe and a solution supply conduit are supported by respective first and second fluid delivery mechanisms which rotate to move the syringe outlet and the conduit outlet in generally arcuate paths toward and away from the flow cell entrance port. The delivery mechanisms are rotated simultaneously, one toward and one away from the entrance port, by a common drive gear. Seating of the wash solution outlet in the entrance port is upstream of the seating of the sample outlet to ensure complete flushing of sample from the entrance port by the wash solution.

摘要： A signal conditioning circuit for extracting unipolar noise from an analog input signal by isolating the unipolar noise component and subtracting it from the input signal. The circuit includes a coupling capacitor receiving the analog signal and an ideal clamp connected to the capacitor output terminal to clamp the capacitor to an edge of the unipolar noise signal. The capacitor is thus prevented from charging toward a level representing an average value of the unipolar noise and hence functions to pass the noise undistorted for subtraction from the analog input signal. The clamp comprises an operational amplifier having a first input terminal connected to the capacitor output terminal and a second input terminal connected to a source of reference voltage. A diode is connected in a feedback path between an output terminal of the amplifier and the first input terminal thereof.

摘要： A method and structure for a display system having multiple spatial light modulators (SLMs) (16), each of which contributes an image of one color that is perceived by the viewer as a combined image. The SLMs (16) have more rows and columns of pixel elements (42) than rows or columns of pixel data to be displayed. A window of "active" pixel elements (42) can be shifted up and down or right and left by selecting which pixel elements (42) are to receive data. The addressing circuit (31, 31a, 35, 35a) of each SLM 16 can be controlled so as to accomplish this shifting.

摘要： A method of adjusting color temperature of images displayed by a display system (10) whose images are based on sequential pixel data and are filtered with a color wheel (15, 15', 15"). The relative display times for each color are adjusted to result in a corresponding adjustment of color temperature. In a first embodiment (FIG. 2), the size of the color wheel's segments are changed as well as the display times for data corresponding to each segment. In a second embodiment (FIG. 3), the display times for data corresponding to one or more segments are decreased with a black display time to fill in the difference.

摘要： A system (30) for packing data into a video processor is provided. System (30) comprises demultiplexer (32), first and second first in-first out buffer memories (34) and (36), and multiplexer (38). Demultiplexer (32) divides a field of video data into first and second parts (42) and (44). First and second parts (42) and (44) are stored in first first in-first out buffer memories (34) and (36), respectively. Multiplexer (38) combines one line from first first in-first out buffer memory (34) with one line from second first in-first out buffer memory (36) to form a single line for processing.

摘要： A SLM-based projection display system (10) samples and processes video data for delivery to a spatial light modulator (SLM) (13c), and uses a color wheel (14a) to color the SLM-generated images. A frame memory (13b) provides data to the SLM (13c) and is managed so that, if the phase of the incoming video signal changes, a desired phase relationship between the color wheel position and the data available to the SLM (13c) can be maintained. Also, a motor control unit (15a) uses a horizontal sync signal to generate a drive signal for the color wheel motor (16a), which limits the transient time during phase-changing events, and which provides a means for adjusting the phase of the drive signal.
