Abstract:
A scanning device includes: a housing portion defining a scanner head axis and a nose end; an image sensor to capture an indicia; an optics component between the image sensor and the nose end to cooperate with the image sensor to define a scanning device FOV extending along a scanning device optical axis through the nose end and toward an object surface, and to convey light reflected from the object surface within the scanning device FOV to the image sensor; and a light source to illuminate the object surface, wherein the scanning device optical axis is tilted relative to the scanner head axis to cause the scanning device FOV to extend along the scanning device optical axis in a direction tilted away from in parallel with the scanner head axis to prevent including a direct reflection of the light source from the object surface in the scanning device FOV.
Abstract:
A battery support for a scanning device includes a separator plate and multiple elongate battery guides. The separator plate includes multiple mounting supports to engage mounting portions of the interior of the head portion to install the separator plate within the casing. The multiple elongate battery guides extend from the handle-side surface of the separator plate into the interior of the handle portion when the separator plate is installed within the casing. The multiple elongate battery guides engage a removable battery as the battery is inserted into a second end of the handle portion opposite a first end to guide a battery mating connector towards a scanner battery connector. The multiple battery guides continue to engage the removable battery while the battery connector engages the mating connector. The multiple battery guides are configured to prevent exertions of physical stress on the battery connector through the mating connector by the battery.

Abstract:
Real-time locating systems (RTLS) for self-shopping systems that utilize a dual technology approach. Self-shopping terminals are equipped with a passive or active ultra-wideband (UWB) tag that includes a UWB backscatter module or a UWB transmitter, respectively, as well as a standard wireless communication transceiver, such as a Wi-Fi® or UHF-RFID transceiver, that enables communication over the wireless communication channel. Readers fixed within a shopping environment activate the UWB tag of a selected one of the self-shopping terminals by addressing the self-shopping terminal using the standard wireless communication channel. Once activated, the UWB tag of the selected self-shopping terminal transmits UWB signals which are received by a plurality of the readers and used to determine the location of the UWB tag and hence the location of the self-shopping terminal. A messaging system may send messages to the self-shopping terminal for presentation to the customer on a display of the self-shopping terminal.

Abstract:
The invention relates to a method of capturing an image on a surface of an object by means of one or more line sensors and a related system, wherein consecutive line images are taken from a plurality of surfaces or surface portions having a different inclination to a given reference plane with a predetermined frequency during a relative movement of said object with regard to one or more of said line sensors and a two-dimensional first image of the surfaces or surface portions is formed from these line images. The method comprises resampling said two-dimensional first image so as to reduce the surface resolution of an image or of images of one or more surfaces or surface portions with regard to a direction oblique to the direction of the lines corresponding to consecutive line images taken by a line sensor in such a way that differences in the surface resolution of images of surfaces or surface portions with different inclination to said reference plane are reduced or eliminated. The system of the invention is adapted to perform such resampling.
