Methods for accurate object tracking are disclosed herein. An example the method includes receiving, from a first optical imaging assembly having a first field of view (FOV), a first image captured over the first FOV and based on a decode of an indicia associated with an object of interest, identifying the object of interest within the first image. The method further includes determining a location of the object of interest within the first image and mapping the location of the object of interest within the first image to a predicted location of the object of interest within a second image, the second image being received from a second optical imaging assembly having a second FOV and the second image being captured over the second FOV.

A sufficient decoding processing time for each image acquired by performing high-speed imaging is secured to obtain a stable reading result, thereby enabling immediate output of the obtained reading result. A processing unit has a first core and a plurality of second cores. The first core instructs the second cores, presumed to be capable of immediately executing the decoding process or executing the decoding process next to a decoding process being currently executed, to execute the decoding process. The second cores are configured to be capable of simultaneously executing the decoding process on read images instructed by the first core at different timings.

A barcode reader having lower and upper housings, a weigh platter in the lower housing, and an off-platter detection assembly. The weigh platter has a proximal edge adjacent the upper housing, a first lateral edge, and a distal edge. The off-platter detection assembly comprises an off-platter indication system having a plurality of linearly aligned light sources, each light source representing a location along the first lateral edge, and controller operatively coupled to the plurality of light sources. The controller is configured to: determine if an object extends over the first lateral edge; determine a location of the object along the first lateral edge; and illuminate a first portion of the light sources representing a distance between the proximal edge of the weigh platter and the object and de-illuminate a second portion of the light sources representing a distance between the object and the distal edge of the weigh platter.

Embodiment of the present invention generally relate to bi-optic barcode readers. In an embodiment, the disclosure describes a barcode reader for use in a checkout workstation having a surface. The barcode reader includes: a lower housing portion having a top portion; a first optically transmissive window positioned in the top portion, a top surface of the first optically transmissive window defining a horizontal plane, the top portion of the lower housing being substantially parallel with the surface of the checkout workstation when the barcode reader is used in the checkout workstation; a raised housing portion having a second optically transmissive window, the raised housing portion extending at least partially above the top portion; and a PCB positioned substantially upright relative to the horizontal plane, the PCB having a first imaging assembly and a decode assembly, the barcode reader having no other printed circuit boards with another imaging assembly.

A POS terminal (code reading device) according to one example embodiment of the present invention includes: a code reading unit that reads information of a code based on a reflected light from the code attached to an item; and a discount processing unit that, when the information of the code is not read by using a first light being irradiated on the code and the information of the code is read by using a second light being irradiated on the code, makes a discount associated with the second light for the item, wherein the second light is different from the first light.

Provided is an optical information reading device that can reduce an installation load on a user, and can accurately read a code provided to each of various workpieces. A polarized illumination light source includes light emitters that irradiate the workpiece with illumination light through a polarization filter. A non-polarized illumination light source includes light emitters that irradiate the workpiece with illumination light without through a polarization filter. An imaging element is provided with a polarization filter having a polarization direction different from a polarization direction of the polarization filter of the light emitters. Either of the polarized illumination light source and the non-polarized illumination light source is used in accordance with the workpiece.

A machine readable symbol reader can provide illumination form portions other than or in addition to the head of the reader, to enhance the ability to successfully read machine-readable symbols, for example symbols on curved surfaces and/or DPM symbols. A machine readable symbol reader include a first set of receiving optics in a head of the reader and a second set of receiving optics in a portion of the reader other than the head, to provide an alternative line of sight or field of view.

A semiconductor device and method of making the same wherein the semiconductor device includes a pFET region including a SiGe channel having a Si-rich top surface within the gate portion, and an nFET region including a Si channel. The method includes subjecting both the pFET and nFET regions to a single high-temperature anneal process thereby avoiding the need for an additional spike anneal process at RMG module.
