摘要： A high speed fluid jet nozzle made at least in part of a porous material and configured so that the porous part of the nozzle is surrounded at least in part by a reservoir containing a lubricant fluid. As a cutting fluid passes through the nozzle, lubricant from the reservoir is drawn through the porous material and lubricates the surfaces of the nozzle exposed to the fluid jet. The invention not only resolves the main difficulties of the prior art relating to nozzle wear, it expands the use and applications of high speed fluid jet cutters. By reducing wear of a jet nozzle, it is possible to increase the jet speed and reduce the nozzle diameter even further than the prior art, allowing much higher precision, deeper cutting, and usage on difficult to cut material such as ceramics. The invention thus provides a reliable but yet very simple method for preventing nozzle wear.

摘要： A pre-analysis chamber having reduced turbulence is provided for a flow particle analyzer. The chamber has a conical diverging section for decelerating sheath fluid flow to form a laminar profile, followed by a conical converging section for accelerating flow. A sample inlet tube is supported in the chamber near the interface between the diverging and converging sections, and terminates in the laminar, accelerated sheath flow. The sample enters the laminar sheath flow to form a discrete sample stream.

摘要： A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read; a first actuator manually displaceable from a first position to a second position for producing a first light beam for aiming or positioning the reader, and a second actuator manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol. The actuators are independently operative of each other. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol.

摘要： A bar code scanner and method for scanning a bar code symbol that splits a light beam using a liquid crystal device and directs the split light beams toward a bar code symbol using a moveable mirror. The light reflected by the symbol from each of the split light beams is added summed and converted to an electrical signal indicative of the bar code symbol. The electrical signal is processed to decode the bar code symbol and, if the decoding is unsucessful, the liquid crystal device is changed to affect the number of split light beams incident on the bar code symbol.

摘要： A plurality of the areas of differing light reflectivity of a bar code symbol or the like are simultaneously illuminated using, for example, a beam of light that has an elongate cross-section. The light beam is swept over the symbol to be read in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time. The reflected light is sensed by a 1D CCD array. A microprocessor within the scanner provides visual feedback to aid a user in aligning the device, and also provides for a selectable aspect ratio for the image, a selectable image resolution and size, a selectable aspect ratio of the illumination, and a selectable pixel size. All of these options may be programmed within the microprocessor, enabling the device to read a large variety of two-dimensional symbols.

摘要： A scanning device for reading indicia of differing light reflectivity, including bar code or matrix array symbols, has a single light emitter, such as a laser or light emitting diode, for generating a scanning light beam to visually illuminate sequential portions of the indicia. A sensor, such as a charge coupled or other solid state imaging device, simultaneously detects light reflected from portions of the indicia and generates an electrical signal representative of the spacial intensity variations the portions of the indicia. The scanning device may also include an ambient light sensor, and a second light emitter for use only in aiming or orienting the scanning device. A photodetector may also be provided to separately detect one symbol virtually simultaneous with the detection of another symbol by the sensor or to provide dual modalities. A method for reading indicia is also provided.

摘要： A bar code scanner employs an electronic means for causing the light beam to scan a bar code symbol, rather than using a mechanical device to generate the scan. A linear array of light sources, activated one at a time in a regular sequence, may be imaged upon the bar code symbol to simulate a scanned beam. Instead of a single linear array of light sources, a multiple-line array may be employed, producing multiple scan lines. The multiple scan lines may be activated in sequence, or activated simultaneously (time-division or frequency-division multiplexed. The multiple scan lines can provide signal enhancement, noise reduction or fault correction if directed to the same bar code pattern. Multiple scan lines may be generated using a single light source and a beam splitter, with mechanical scanning, as well as by the sequentially-activated light sources. Multiple simultaneous scan lines may be employed to generate a raster scan at lower mechanical scan frequency. In another embodiment, a tunable laser may be employed to provide a scan without moving parts; a laser beam from the tunable laser is reflected from a diffraction grating that produces an angular deviation dependent upon the wavelength of the laser output. As the frequency of the tunable laser is varied in some selected pattern, the laser beam will scan accordingly.

摘要： To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. A flexible support structure, such as one or more strips of mylar, movably mounts the light emitter in response to a motive force, for example as might be applied by a combination of a permanent magnet coupled to the light emitter and a fixedly mounted electromagnet driven by an alternating current signal. Reciprocation of the light emitter during emission of light by the light emitter causes the light to scan a surface, such as a surface beating a bar code label.
