An energy harvesting device and a display device are provided. The energy harvesting device is configured to generate a power signal and the energy harvesting device includes a slot antenna. The slot antenna comprises a first section and a second section. The first section of the slot antenna is a linear shape and comprises an opening end, and the second section of the slot antenna is a bending shape and comprises a plurality of continuously bending corners.

Provided is a computing technology for controlling information display of an electronic shelf label that is connected to a management server via a network and displays electronic information. The electronic shelf label measures a distance to at least one product arranged behind the electronic shelf label, and when a change in the distance occurs, activates a wireless tag reader. When product identification information acquired by the wireless tag reader is different from currently displayed product identification information, the electronic shelf labels request a label change registration to a server. Changed product information is received according to the label change registration, and the changed product information is reflected in displayed product information.

Systems and methods for controlling electronic shelf labels are disclosed. Product data identifying at least one product and a price of the at least one product and layout data of a physical environment including locations of one or more shelves, a respective shelf location of the at least one product, and coordinates of a plurality of electronic shelf labels is received. Coordinates for a first electronic shelf label associated with the respective shelf location is determined. A first emitter of a plurality of emitters that is capable of communicating with the first electronic shelf label is determined and positioned to direct a signal to the coordinates of the first electronic shelf label to establish a link with only the first electronic shelf label. A portion of the product data is transmitted via the signal, which causes the first electronic shelf label to display the portion of the product data.

A method for controlling remotely controlled displays, such as electronic price tags, of a remotely controlled display system, and a remotely controlled display system including at least one base station and a plurality of remotely controlled displays, such as electronic price tags. The remotely controlled displays are arranged in premises, such as a store, and include a light source, e.g. an LED light source. The system is adapted to provide guidance to people, such as emergency exit guidance, by turning on and/or off the light sources of the remotely controlled displays in a pre-determined manner.

An electronic label with a housing, that comprises a front wall and a rear wall and a side wall, wherein the front wall comprises a, particularly reflective, screen, and wherein by contrast to the front wall and rear wall, the side wall is constructed to be light-conducting and wherein a light source for emitting the light that can be generated using it through the side wall is positioned inside the housing, and wherein the side wall is inclined towards the front wall.

The invention relates to an electronic shelf label system that comprises a server for delivering shelf label display information to a number of display devices that are controlled by the server to display said shelf label display information on their screens, wherein said screen is designed to display video content represented by received video data, and said display device is designed to deliver video data to a screen and to receive label positioning data for defining the position of the shelf label display information in the display area of at least one of the screens connected to it, and to embed the shelf label display information in accordance with the received location data in the video content that is delivered to said screen.

A shelf tag attachment apparatus (100) includes a shelf tag holding portion (103) for holding an electronic shelf tag (101), and a support member (102) that supports the shelf tag holding portion rotatably about a rotation axis P extending in a left-right direction of the electronic shelf tag (101). The shelf tag holding portion (103) includes a bearing portion for rotating about the rotation axis P relative to the support member (102). The support member (102) includes an arm portion (110) that is provided with a shaft portion (112), and that sandwiches the bearing portion from the left-right direction. The shelf tag holding portion (103) includes a stopper (130) that contacts the arm portion (110), and thereby locks in such a way that a display surface (104) of the electronic shelf tag (101) does not rotate beyond a previously determined range in a direction to face downwards.

Systems and methods that employ an autonomous robotic vehicle (ARV) alone or in combination with a remote computing device during the installation of electronic shelf labels (ESLs) in a facility are discussed. The ARV may detect pre-existing product information from paper labels located on modular units prior to their removal and then detect the location of electronic shelf labels (ESLs) after installation. Pre-existing product information gleaned from the paper labels is associated with the corresponding ESLs. The ARV may also determine compliance or non-compliance of modular units to which an ESL is affixed with a planogram of the facility.

One broad aspect of the invention features a shelving facing display. The shelving facing display includes a housing, an electronic display, and multiple product sensors. The housing is mountable to a forward edge of a product shelf. The electronic display is mounted to the housing and arranged to be viewed from in front of the shelf. The electronic display is controllable to present desired images across at least a majority of a width of the shelf. The multiple product sensors are mounted to the housing. Each sensor is arranged to detect product on a respective width of the shelf. The display is configured to alter a displayed image in response to input from the product sensors.

Disclosed herein are electronic shelf-tag systems and methods thereof. For example, an electronic shelf-tag system includes, in some embodiments a fascia configured to mount to a shelf of a shelving unit and a light-emitting diode (“LED”) array coupled to the fascia. The LED array is configured to display product information in a shared electronic shelf tag for two or more products respectively stocked in two or more consecutive shelf slots when a horizontal resolution of a portion of the LED array corresponding to at least one shelf slot of the two or more consecutive shelf slots is insufficient for displaying the product information for the product stocked in the at least one shelf slot.
