摘要： There is provided in one embodiment an indicia reading apparatus with enhanced functionality which can filter image data prior to the capture of image data into an image frame memory for further processing. In one aspect the indicia reading apparatus can have an image sensing and processing circuit that can contemporaneously output, on respective first and second interfaces, both filtered and raw pixel values so that both filtered and raw frames of image data can be captured contemporaneously for further processing. Filtered and raw frames of image data or pixel values can also be serially output through a single interface in an interleaved manner. An image sensing and processing circuit which outputs either or both raw and filtered pixel values can be provided on a single integrated circuit. In another aspect an image sensing and processing circuit can be provided that develops data indicating a location of a decodable indicia representation within image data prior to capture of a frame of image data into an image frame memory so that when pixel values are first addressed for further processing, a decodable indicia representation such as a bar code representation has already been located. By processing of image data within an image processing circuit prior to capture into an image frame memory a trigger to read time (TTR) can be reduced.

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： The invention enables a registered PEAD user to exchange a secure message with another registered PEAD user by using the user ID and the user public key information in the server. The sender can retrieve the public key information from the server 1201 using the receiver's user ID as an index; then the sender can derive the shared secret using the receiver's public key. The sender then can encrypt the message with the shared secret and send it over to a server with the other PEAD user's (receiver's) ID appended with the sender's user ID over the wireless network and/or Internet. The server then stores the message and forwards the message to the receiver once the receiver's PEAD is polling for messages. (It is understood in the art that the server can push the messages to the receiver's PEAD).The receiving PEAD user can use the sender's PEAD user ID and sender's public key information to derive the shared secret to decrypt a received secure message. Once a shared secret is computed or established by protocol between two users, that shared secret can be saved in the PEAD for future communication encryption/decryption usage.
