A two-dimensional code is attached to a location of a reagent storage unit which is visually recognizable from the outside, and a coordinate position of the two-dimensional code in a coordinate system of the two-dimensional code and coordinate information of an installation position of a reagent bottle are held. After that, an image of the two-dimensional code is captured by a portable terminal so that a coordinate system of an image capture unit of the portable terminal is converted into the coordinate system of the two-dimensional code using AR technology. The coordinate information of the installation position of the reagent bottle in the coordinate system of the two-dimensional code is regarded as positional coordinates in the captured image on the basis of the conversion, thereby ascertaining the position of the reagent bottle on the captured image and displaying the ascertained position on a display unit.

An optical information reader includes an imaging lens and a lens retainer retaining the imaging lens and assembled, in this state, into the holder. The lens retainer includes a flange bottom surface and end faces as a reference surface that is parallel to an optical axis of the imaging lens. The holder includes a top surface and edge faces as a guide surface. The guide surface is brought into surface contact with the flange bottom surface and the end faces when the lens retainer is assembled into the holder, and is brought into slidable contact with the flange bottom surface and the end faces when the lens retainer is moved along the optical axis. Thus, influence of one-sided blur is minimized in terms of variation in resolution which is measured when obtaining an optimal focus position by changing relative positions of the area sensor and the imaging lens.

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.

This disclosure relates to a communication system where a user can use a smart phone to scan a tag, such as a QR code, to retrieve a weblink. The weblink is unique and associated with the location of the tag, which may also be the location of an unpersonalised device, such as a video projector or other A/V equipment. Therefore, when the mobile phone connects to the weblink, the webserver can retrieve information associated with this particular unique code. This information is now specific to the location of the tag and may even include information about the unpersonalised device. The operator receives the information when the communication channel is established and therefore knows exactly what the subject of the call will be. Further, the call can be automatically routed to the most appropriate operator without audio menus to be navigated by the user.

A wireless, Bluetooth® paired connection is established between a wireless, electro-optical reader and a host by reading a multi-parameter, pairing symbol displayed by the host. An identification parameter is extracted from the pairing symbol to automatically identify the host, and one or more configuration parameters are substantially simultaneously extracted from the same pairing symbol to automatically configure the paired connection between the reader and the host.

An electrosurgical return electrode configured for operable association with a transponder detection unit. The return electrode includes a conductive element having an aperture array configured to allow passage of a magnetic, electric, or electromagnetic interrogation signal from the transponder detection unit through the conductive element and through the return electrode. The return electrode is positionable over a transponder detection unit such that the return electrode may be placed upon the transponder detection unit and a patient may be positioned upon the return electrode. The return electrode enables the detection of a transponder located on, within, and/or near the patient without the need for repositioning the patient relative to the return electrode and without the need for positioning an ancillary transponder reader or transmitter above the patient.

Dimensions of an object associated with an electro-optically readable code are estimated by aiming a handheld device at a scene containing the object supported on a base surface. A scanner on the device scans the scene over a field of view to obtain a position of a reference point of the code associated with the object, and reads the code. A dimensioning sensor on the device captures a three-dimensional (3D) point cloud of data points of the scene in automatic response to the reading of the code. A controller clusters the point cloud into data clusters, locates the reference point of the code in one of the data clusters, extracts from the point cloud the data points of the one data cluster belonging to the object, and processes the extracted data points belonging to the object to estimate the dimensions of the object.

A method and apparatus for performing a process associated with an item to be imaged is disclosed. The process requires data associated with a plurality of required features of the item to be imaged. A handheld device is used to obtain a sequence of images. For at least a subset of the obtained images, a camera field of view is directed toward the item from different relative juxtapositions while obtaining the images. At least a subset of the obtained images are examined to identify the required features. Images are obtained until each of the required features are identified in at least one image. Feedback is provided to a user indicating at least one additional required features to be imaged, required features that have already been imaged and guidance indicating how to manipulate the handheld device to obtain images of additional required features.

To achieve an information output device in which information of a medium disposed on a stage surface can be surely and efficiently read out, and a stage effect and a security are high. In the information output device, media are disposed on a stage surface in a state where the media are opposite to the stage surface, the media where dot patterns are printed on medium surfaces on the basis of a predetermined rule, the dot patterns are read by imaging units disposed in a space below the stage and converted into code values or coordinate values indicating the dot patterns from photographed images obtained by the imaging units, and information corresponding to the code values or the coordinate values is outputted. Further, light transmitting reading holes are respectively provided at a plurality of medium disposing locations on the stage surface, and the imaging units are disposed in the space below the stage corresponding the respective reading holes such that the imaging units photograph the medium surfaces of the media disposed on the reading holes.
