摘要： The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

摘要： Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.

摘要： A scanning apparatus comprises a laser source adapted to emit a beam along an axis and illuminate a target, a detector adapted to receive light of varying intensities scattered from the target and convert the light into a signal, and a controller operatively associated with the detector for receiving the signal from the detector and decoding the signal. A focusing apparatus comprising a deformable lens element in optical communication with the laser source has a deformable surface, at least part of which transmits the beam. The deformable lens element defines an index of refraction difference with an index of refraction of an adjacently disposed substance. In one embodiment the index of refraction difference is greater than 0.30.

摘要： A portable data terminal (PDT) adapted to participate in a wireless mesh network including a plurality of peer PDTs can comprise: a PDT module including an encoded information reading (EIR) device, and a mesh point (MP) module communicatively coupled to the PDT module. The MP module can include a microcontroller and at least one wireless communication interface and can be configured to perform IEEE 802.11-conformant wireless station services including authentication, de-authentication, privacy, and MAC service data unit delivery, and IEEE 802.11-conformant wireless distribution system services including association, disassociation, distribution, integration, and re-association. The MP module can be further configured, responsive to receiving a MAC frame addressed to a recipient inside the wireless mesh network, to deliver the MAC frame using the distribution service. The MP module can be further configured, responsive to receiving a MAC frame addressed to a recipient outside of the wireless mesh network, to deliver the MAC frame using the integration service. The MP module can be further configured to route an incoming MAC frame according to its destination address and the frame control field. The MP module can be further configured to cause the PDT module to exit said sleeping state responsive to receiving a mobile management software (MMS) wake-up command.
