Extreme Networks has filed a patent for a handheld barcode reader that includes a housing with a head portion and a base portion, a vision camera in the base portion, and a barcode reading module in the head portion. The device also has a controller that decodes barcodes, receives images from the camera, and synchronizes the camera and barcode module to prevent image capture while the module is active.

Handheld barcode reader with synchronized vision camera and barcode module
A recently filed patent (Publication Number: US20230316016A1) describes a handheld barcode reader with several unique features. The device consists of a housing that includes a head portion and a base portion. The base portion contains a vision camera with a field-of-view (FOV) directed through a base window, while the head portion houses a barcode reading module with a separate FOV directed through a scan window.
The handheld barcode reader also includes a controller that is in communication with both the barcode reading module and the vision camera. The controller is responsible for decoding barcodes read by the barcode reading module, receiving captured images from the vision camera, and synchronizing the two components. Importantly, the controller ensures that the vision camera does not capture images when the barcode reading module is active, preventing any interference between the two functions.
The housing of the barcode reader also features a handle portion between the head and base portions. This handle portion is visible within the FOV of the vision camera, allowing the user to see the area adjacent to the handle while scanning barcodes.
Additionally, the base portion of the handheld barcode reader is designed to be modular. It consists of an upper portion and a lower portion that can be removably attached. The upper portion contains the base window, while the lower portion includes the vision camera. The lower portion can be switched out with another lower portion that does not include the vision camera. This modular design allows for flexibility and customization of the device.
The FOV of the vision camera at least partially overlaps with the FOV of the barcode reading module. The FOV of the vision camera has a horizontal viewing angle between 80 and 120 degrees, with a specific angle of 100 degrees. On the other hand, the FOV of the barcode reading module has a horizontal viewing angle between 40 and 60 degrees. The controller is programmed to activate the barcode reading module when an object is detected in the FOV of the vision camera.
Furthermore, the handheld barcode reader may include an optical sensor positioned in the base portion. This optical sensor has a third FOV that overlaps with the FOV of the barcode reading module. The controller receives signals from the optical sensor and uses them to synchronize the barcode reading module and the vision camera.
Overall, this patent describes a handheld barcode reader with a unique design that allows for efficient barcode scanning while preventing interference between the barcode reading module and the vision camera. The modular base portion and the inclusion of an optical sensor provide additional functionality and customization options for the device.
