|An apparatus and method for expediting self-checkout at a point-of-sale station, |
employ a mobile electronic device, e.g., a cellular phone, held and operated by
each customer. The device images one-dimensional symbols identifying items to
be purchased, decodes the one-dimensional symbols to form ...
|A laser diode in a scanner (10) is deactuated during part of each scan to |
conserve power and to increase the working lifetime of the diode (33) and of a
battery for powering the scanner. The dead zone in which specular reflection may
prevent a successful reading of the symbol is minimized. The scanner ...
|An aperture stop (50) focuses light from indicia onto a solid-state imager (40) of |
an imaging reader The aperture stop has an open aperture (52) with a scan
dimension sized to resolve symbol elements, and with a height dimension to
allow sufficient light to be captured A cylindrical lens can be used to ...
|Laser power control arrangements interrupt power to a laser used in electro-|
optical readers upon detection of an over-power condition not conforming to
preestablished standards to meet prevalent safety standards.
|A cable interlock for connecting a scanning head via a cable to a remote device |
|An optical slot scanner (10) includes a housing (12) supporting a scanning |
arrangement (22), within an interior ...
|An optical scanner such as a bar code scanner includes a segmented mirror (14), |
the individual sections of which have different profiles (16,18,20). By directing the
scanning laser beam across the mirror, a plurality of scan lines are created, at
different distances from the scanner. This provides increased ...
|An optical scanner such as a bar code scanner includes a segmented fold mirror, |
the individual sections of which have different profiles. By directing ...
|The operating condition of data capture systems, such as electro-optical readers (|
10), RFID readers, and imagers, is monitored an reported to a host which
preferably modifies the operating condition (26, 27, 36, 41) when the latter is
outside a ...
|A portable scanning head emits and receives light from a light-emitting diode to |
read symbols, such as bar-code symbols. The optics within the scanner are
operative for focusing a light beam and the view of a light sensor in different
planes exteriorly of a scanner housing, Imaging means are provided in the ...
