Abstract:
Eine Vorrichtung und ein Verfahren zum Beschleunigen der Selbstbedienung an einem Point-Of-Sale-Terminal verwenden ein von jedem Kunden gehaltenes und bedientes mobiles elektronisches Gerät, z. B. ein Mobiltelefon. Das Gerät bildet eindimensionale Symbole ab, die zu erwerbende Waren identifizieren, decodiert die eindimensionalen Symbole, um decodierte Daten zu bilden, kombiniert die decodierten Daten, um ein oder mehrere zweidimensionale Symbole zu bilden, und zeigt jedes zweidimensionale Symbol auf einem Anzeigebildschirm an. Jedes angezeigte zweidimensionale Symbol wird einem Fenster eines elektrooptischen Scanners am Point-Of-Sale-Terminal präsentiert. Der Scanner bildet jedes angezeigte zweidimensionale Symbol ab und decodiert es, um eine Reihe decodierter Daten zu bilden, die alle eindimensionalen Symbole angeben, und sendet die Reihe decodierter Daten an ein Hostnetz.
Abstract:
A plurality of solid-state imagers is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing images along different fields of view of diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. The imagers are commonly mounted on a circuit board for joint installation at, and joint removal from, the reader for ease of serviceability.
Abstract:
Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields.that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield.
Abstract:
Described is a shock protection arrangement comprising a flexure coupled to a first magnet and a second magnet positioned adjacent the first magnet. The second magnet is oriented so that a repellant magnetic force generated by the second magnet resists motion of the first magnet when there is a predetermined distance between the first and second magnets.
Abstract:
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 decoded data, combines the decoded data to form one or more two-dimensional symbols, and displays each two-dimensional symbol on a display screen. Each displayed two-dimensional symbol is presented to a window of an electro-optical scanner at the point-of-sale station. The scanner images and decodes each displayed two-dimensional symbol to form a series of decoded data indicative of all the one-dimensional symbols, and sends the series of decoded data to a host network.
Abstract:
A system for, and method of, enhancing product selection and purchase in a retail environment, utilizes a handheld device that includes a cellular telephone operative for long-range, mobile, wireless communication over a wide cellular network, a solid-state imager having an array of image sensors for capturing return light from a target, and a communications interface operative for short-range, mobile, wireless communication over a local network associated with the retail environment. A controller is operatively connected to the telephone, the imager and the interface, and is operative for automatically pairing the handheld device with the local network by operating the imager to capture the return light from a command target code associated with the retail environment.
Abstract:
Combining one or more elements of a beam shaping assembly in a lens module to, for example, reduce the mechanical tolerances in construction of the assembly. An exemplary lens module comprises a molded plastic lens with alignment features, a cylindrical surface, a focusing surface, and an aperture. The aperture is formed by surface positioned on the lens module at an angle greater than the angle for total internal reflection.
Abstract:
An optical slot scanner (10) includes a housing (12) supporting a scanning arrangement (22), within an interior region (14) of the housing, including an imaging camera (26) and a light source (24) disposed within a recess compartment (80) located in the housing (12). The imaging camera has an imaging field of view (40) for reading indicia on a target object. The light source (24) has an illumination field (42) for illuminating the targetted indicia such that the illumination field (42) is substantially coaxial with the imaging field (40) during indicia reading. Also, the light source (24) is coupled to an object-detection sensor (92) for actuating said light source (24) upon indicia detection.
Abstract:
An apparatus for and method of electro-optically reading targets arbitrarily oriented in a workstation, such as a dual window workstation, employs a solid-state imager for capturing return light from the targets over a field of view. The imager has an array of sensors arranged along mutually perpendicular array axes. An optical system splits the field of view into a plurality of subfields of view that extend through a workstation window to a target. One subfield is optically configured to enable the imager to capture light from the target along one array axis. Another subfield is optically configured to enable the imager to capture light from the target along the other array axis. A controller processes the captured light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.
Abstract:
Methods and apparatus for providing a relatively miniature injection molded scan motor, for example, for a retroreflective illumination system. An exemplary scan motor comprises a spring module that includes a static substrate and a dynamic substrate coupled together by an injection molded flexible spring. In an embodiment, the spring can be liquid injection molded. The scan motor also comprises a magnet and a reflective element that extends beyond the static substrate and/or the dynamic substrate.
