摘要： An intravenous system for monitoring the flow of IV fluids to a patient is embodied in a wristwatch sized unit for placement on the patient. The device includes a flow indicator switch capable of detecting when flow starts or stops. In one embodiment, the range of flow rates which may trigger a signal is increased using a plurality of sensor elements. The flow indicator switch uses a conical chamber with a movable flow element which reacts to the motion of the IV fluid. A light emitter-sensor arrangement provides a means for converting physical displacement into an electrical signal indicating displacement of the movable member.

摘要： A bulk stream detector for a conduit (4, 5) feeding granular, hygroscopic material to be filled into spacer frames (3) for insulating glass from a storage container to a filling head (1) comprises a punctiform light source (8, 9) connected to the conduit (4, 5), this light source emitting a light beam (11) traversing the conduit. A sensor (10) responding to the light (11) emitted by the light source (8, 9) is arranged in opposition to the light source (8, 9). The sensor (10), under the effect of the light impinging thereon from the light source (8, 9), transmits a signal to a control unit (12, 13) which latter, in turn, transmits a signal if, during a preselected period of time after the last signal transmitted by the sensor (10), no signal has been received from the sensor (10).

摘要： A fertility analyzer includes a laser beam impinging on a sperm sample in a capiliary, a first optical system including at least a first lens focusing the laser beam in the sample, and a second optical system including at least a second lens, a first diaphragm determining the volume element of the sample to be monitored, a second diaphragm determining the space angle of scattered light and a light intensity detecter. A signal processing device stores the signals from the light detector during a predetermined time separately for beams outgoing from the sperm sample in at least two chosen directions and computes at least two features having relation to the fertility of the sperm sample. A separator included in the combination of the first and second optical systems sorts out a determinable small section of the beam outgoing from the sperm sample in a direction lying in a plane approximately parallel to a plane including the capillary.

摘要： The invention concerns the flow and measurement of divided solids in small diameter tubes at high pressures. A flow channel is drilled through a metal block. A second channel is drilled so that the second channel intersects the first channel at a right angle. A beam of light, sent through an optical fiber in the second channel, travels across the first channel and is received and recorded in the distal end of the extension of the second channel. Interruptions of the light beam, due to the passage of solids along the first channel, are translated into indications of the flow of the solids.

摘要： A laser velocimeter that determines the direction of movement of particles. A laser produces a transmitted beam that illuminates the volume under investigation. The backscattered light is divided into two equal intensity beams. A first part of a sample of the transmitted beam is mised with one of the two equal intensity beams and applied to a first photodetector. A second part of the sample is phase shifted by 90.degree., mixed with the other of the two equal intensity beams and applied to a second photodetector. The output of the first photodetector is phase shifted by -90.degree. and then multiplied with the output of the second photodetector to produce a signal indicative of direction of movement.

摘要： A photo detecting flow sensing bending beam fluid flow switch and flow meter system having blocking targets that selectively block the optical path from an emission source to a photodetector. The device provides a system which is very sensitive to fluid flow in a pipe, container or duct by providing a shaped flexible flow sensitive bending beam having a blocking target which is bent so that the portion of the blocking target is displaced between the emission source and a photodetector. The shaped blocking target is configured to either interrupt or permit the transmission of emission from the emitter to the photodetector. The presence or absence of the source represents the presence or absence of a fluid flow rate above or below a selected value thus, performing a fluid flow switch function. By modifying the blocking target to provide a reflective control from an emission to a photo detector or an absorption of the emission by a target varying in opacity, the relative light output is continuously modulated to produce a voltage output directly proportional to the rate of fluid flow past the target on a flow sensitive bending beam. In an optional embodiment, flow sensitivity is improved by adding vortex shedding enhancements to the flow sensitive bending beam. This combination of functional elements can provide an analog fluid flow meter transducer for flow metering, totalizing in a flow monitoring system having single or multiple flow switching set points.
