According to various aspects and techniques to enable methods and systems for a first communication device to determine an approximate number of other communication devices that have lost contact with a host communication device. This includes determining a common future time window using a last known global time stamp and determining a transmit time within the common future time window. This also includes receiving samples that are captured during the common future time window on a predefined communication channel, as well as analyzing the received samples to estimate the total number of other communication devices.

The present invention is a message updating system for an electronic label. The system comprises a message updating device, wherein a controller thereof controls a power-supply transmission unit and a message-update transmission unit to respectively transmit a charging signal and a message-updating to the electronic label for charging the electronic label and updating label information of the electronic label. A detection device picks up the label information to generate label content information, transmits the label content information to the controller to make the controller compare the label content information with update comparison information, and generates an alert message if the label content information is different from the update comparison information. The present can charge the electronic label that is mounted on an article and update label information simultaneously while the article is being transported.

An electronic shelf label that comprises: a display unit that is arranged to display an image, and an interaction interface which is arranged separate from the display unit, wherein the interaction interface is realized as touch sensitive unit that provides a touch-triggered signal, and a processing unit that is connected to the touch sensitive unit and is arranged to process the touch-triggered signal.

A method of controlling a display device is provided. The method includes a transparent screen to recognize a position of a user in front of the transparent screen and an eye gaze of the user looking at the transparent screen, recognize a position of a background object behind the transparent screen, estimate, based on a distance between the transparent screen and the user, and a direction of the eye gaze of the user, a minimum angular change of the eye gaze by which the display device is able to detect a change in the eye gaze, and display, on the transparent screen, information related to the background object when the background object is at a position within the minimum angular change of the eye gaze from a current eye gaze of the user.

According to an embodiment of the present disclosure, an electronic shelf label capable of touch input includes a display configured to receive touch input from a user and display information to a user on a screen; and a controller configured to control the screen displayed by the display based on the input received through the display, the controller is configured to: control the display to be operated in a consumer mode in which product information is displayed to the user or a manager mode in which a screen displayed in the consumer mode is set.

The present disclosure relates to a label for an injection device. The label includes a flexible substrate configured for attachment to a body. The label further includes a first label area on the substrate provided with a first information content, wherein the first information content includes at least one visual sign or character. The label further includes a second label area on the substrate non-overlapping with the first label area, wherein the second label area includes an electronic display configured to display a second information content, The label further includes a processor connected to the electronic display and configured to modify at least the second information content.

An electronic shelf label that comprises a display unit that is adapted to display an image, wherein the electronic shelf label is adapted to operate in a customer-oriented information presentation mode in which the image represents customer-oriented information, and to operate in a staff-oriented information presentation mode in which the image represents staff oriented information, and to detect the approach of an external freely movable radio communication device relative to the electronic shelf label based on a received radio signal transmitted by the radio communication device, and to automatically activate the staff-oriented information presentation mode upon the detection of the approach of the radio communication device.

A dynamic information tag is disclosed for performing a dynamic information tag operation. The dynamic information tag includes a tag housing, the tag housing being sized to fit within a recess of an information handling system configured for receipt of a static information tag; a control and connection portion; and, a display coupled to the control and connection portion, the display being controlled via the control and connection portion to present information handling system information, the information handling system information comprising dynamic branding information.

An electronic shelf label system comprising an electronic display device and a plurality of electronic shelf labels is provided. A computing system transmits data transmissions to the plurality of electronic shelf labels. Each of the electronic shelf labels are configured to receive, from the computing system, data to render on an electronic display of each of the electronic shelf labels. The electronic display device is configured to determine, based on at least one of a set of specified conditions or the data rendered on each of the electronic shelf labels, content to be rendered on the electronic display of the electronic display device, and adjust the display of the electronic display device to render the content based on the determination.

A method and system for displaying and managing products with artificial realities. An N-layer digital image is created that includes an M-layer hierarchy of vector images and/or visual overlays in progressive resolution format and allows progressive resolution display without loss of image quality for selected plural consumer products that appear in the N-layer digital image. Plural artificial reality objects are created with physical location information and product information. Consumer products are displayed via the N-layer digital image from a server network device via a communications network whenever a target network device matches a current physical location included in the physical location information in an artificial reality object.
