Computer-implemented systems and methods implement a unified workflow to capture data representing the usage of both sterile and non-sterile surgical assets. Such capture may be performed within, or at the edge of, the sterile field. Item usage data about both sterile and non-sterile items may be machine-captured, such as by using one or more of a bar code reader, RFID tag reader, and image capture device. The item usage data about both sterile and non-sterile items may be captured and stored into a single data store by a single software application executing on a single computer, and displayed by that software application in a single user interface. A user may provide input to that software application to certify both the sterile and non-sterile item usage data.

A data capture device for a building system has a housing in which a display device, an optical reading device, and a first reading device are arranged and which are communicatively connected to a control device arranged in the housing. The optical reading device is embodied to optically detect information from a first information carrier, wherein the optical reading device is arranged in such a way that light from the direction of the front side of the housing, which is accessible to a user, can be captured by an image sensor of the optical reading device. The first reading device has a first antenna in order to detect information from a second information carrier by means of radio communication, the first antenna comprising an air coil which has an inner space. The image sensor of the optical reading device is arranged entirely or partially in the inner space of the air coil.

A matrix bar code on a surface may comprise a plurality of colors and an ultraviolet layer. The matrix barcode may be a fiducial marker for conveying spatial information. The The conveyed spatial information may stem at least in part from the ultraviolet layer.

Techniques to improve detection and security of images, including formation and detection of matrix-based images. Some techniques include logic to process image data, generate one or more colorspaces associated with that data, and perform colorspace conversions based on the generated colorspace. The logic may be further configured to generate an image based on the colorspace conversions, including but not limited to a matrix bar code. The logic may be further configured to apply one or both of an ultraviolet layer and an infrared layer to the image, e.g. matrix barcode, generated from the colorspace conversion(s). Other embodiments are described and claimed.

An example method for charging a barcode reader that can be implemented by a charging cradle includes: detecting that the barcode reader is coupled to a first interface of the charging cradle for the barcode reader; detecting that a spare battery of the barcode reader is coupled to a second interface of the charging cradle; receiving, via a connection between the charging cradle and a port of a host power source, an indication of a magnitude of an input current that the host power source is capable of delivering to the charging cradle over the connection; comparing the magnitude of the input current to a threshold magnitude; responsive to the comparing, determining a charging order in which to charge the barcode reader and the spare battery using the input current from the host power source; and charging the barcode reader and the spare battery in accordance with the charging order.

Disclosed are systems, methods, and non-transitory computer-readable media for geofence based QR codes, Geofences are used to define a geographic location-based restriction on the use of QR codes. For example, geofence data embedded in a geofence based QR code defines the boundary of the geographic region in which the QR codes may be accessed. When a geofence based QR code is scanned, the geofence data is extracted and compared to a current geographic location of the client device used to scan the geofence based QR code, if the location of the client device is within the geographic boundary defined by the geofence, the digital content item associated with the geofence based QR code is presented on the display of the client device. Alternatively, the digital content item is not presented if the location of the client device is not within the geographic boundary.

A camera based code reader is provided that has an image sensor for detecting image data having an optical code, a memory for storing image data, a first processing unit for transmitting the image data from the image sensor to the memory in an image data stream, and a second processing unit that is configured for a decoding in which the stored image data are evaluated to read the code content of the optical code, In this respect, the first processing unit is configured for at least one auxiliary function in which the first processing unit reads back at least some of the image data from the memory and writes a pre-processing result back to the memory; and in that the second processing unit is configured to invoke the auxiliary function of the first processing unit as required to assist the decoding.

A method for an imaging module can include rotating an imaging assembly that includes an imaging device about a first pivot point of a bracket to a select first orientation, fastening the imaging assembly to the bracket at the first orientation, rotating a mirror assembly that includes a mirror about a second pivot point of the bracket to a select second orientation, and fastening the mirror assembly to the bracket at the second orientation. An adjustable, selectively oriented imaging assembly of a first imaging module can acquire images using an adjustable, selectively oriented mirror assembly of a second imaging module.

Techniques for pre-configuring a barcode reader device for establishing a communication link with a particular computing device via a short-range communication protocol are provided herein. An example method includes sending, by a barcode reader device, a request to a computing device via a first short-range wireless communication protocol (e.g., NFC); receiving, by the barcode reader device, from the computing device, via the first short-range wireless communication protocol, an indication of one or more barcode reader device settings for establishing a short-range communication link with the computing device via a second short-range wireless communication protocol (e.g., Bluetooth®); modifying, by the barcode reader device, the one or more barcode reader device settings as indicated; and establishing, by the barcode reader device, the short-range communication link with the computing device via the second short-range wireless communication protocol.

Methods for human characteristic and object characteristic identification at a point of sale (POS)) are disclosed herein. An example method includes capturing, a series of image frames of a product scanning region for each item passing through the product scanning region at the POS workstation. A first set of image frames of the series of image frames for each item may be captured using a first illumination setting configured for a first background brightness level, and a second set of image frames of the series of image frames for each item may be captured using a second illumination setting that is configured for a second background brightness level. The first set of image frames may be analyzed to identify an individual associated with the item, and the second set of image frames may be analyzed to identify the item.
