摘要： A system for reading optical codes, and more particularly to code reading systems with sound signal generators, modules a sound detector detects an ambient sound level in a vicinity of the system operator and the volume of the audible indicator is controlled in response to the detected ambient sound level. The sound may be produced by a transducer located in a raised rail adjacent the system operator. Various kinds of audio signals may be produced, for example, to distinguish the system's response from those of nearby optical code reading systems or to identify the kind of optical code symbology being read or its informational content.

摘要： A scanner module for use in a bar code reader has a scanning mirror which is mounted to a bracket by way of leaf-spring, allowing the mirror to oscillate in one direction. The bracket is hung from a stationary chassis by means of two strips of mylar film, allowing the entire bracket to oscillate in the perpendicular direction, thereby providing two dimensional oscillation of the mirror and raster scanning of a light beam reflected from the mirror. The mylar sheets are protected against mechanical shock by pins which pass through holes in the bracket. The pins are slightly smaller than the holes, allowing sufficient clearance for movement of the bracket during normal operation, but preventing too much stress being placed upon the mylar films if the module is dropped. The pins also provide accurate alignment of the bracket with respect to the chassis.

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 objective lens in front of the light emitter. The objective lens is laterally reciprocated in response to a motive force, for example as might be applied by a combination of a permanent magnet coupled to the objective lens and a fixedly mounted electromagnet driven by an alternating current signal. Reciprocation of the objective lens during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label.

摘要： Containers for holding goods are provided with a relay conductive structure for relaying RFID tags signals from one side of the container to another. The conductive structure includes a first antenna on the first side of the container, a second antenna on a second side of the container and a transmission line connecting the antennas. When the containers are arranged in a stack, the relay of RFID signals past each row of containers enables the interrogation toward the rear of the stack without disassembling the stack of containers.

摘要： A method of reading bar code symbols includes determining one or more parameters based upon the quantity and/or quality of the data which is being acquired, and providing the user with information concerning that parameter. The parameter may, for example, be the rate at which code words in the symbol are being read, and that information may be passed to the user by way of an LED which flashes at a rate which varies with the data acquisition rate. For a given bar code symbol being read, the rate of flashing varies with the position of the bar code reader with respect to the symbol. To improve the data acquisition rate, the user simply moves and/or rotates the bar code reader with respect to the symbol in a direction which causes the rate of flashing to increase. The invention extends to a bar code reader having means for providing an indication to a user of the relative suitability, for optimal reading of a symbol, of the current position of the reader.
