Abstract: An electronic display including a screen including an outer perimeter and front surface. A housing including a screen frame may surround the outer perimeter, and extend in front of the front surface of the screen. An optical sensor shield may be positioned at least in part in the screen frame and extend in front of the front surface of the screen.

Abstract: A system and method for tracking a shopping cart in a retail store may include communicating signals into the pathways from multiple locations, where the signals may include identifiers indicative of location of respective signals. The communicated signals with the identifiers may be received, and the identifiers may be recorded. The recorded data may be processed to determine a path taken by the shopping cart through the retail store. The path of the shopping cart taken through the retail store may be presented to a user.

Abstract: A power bus system and method for providing electrical power to an electronic device at a shelf of a gondola in a retail environment may include a power track including a structure member and at least two electrical conductors. The structure member may be positioned along a bottom surface of the shelf of the gondola. A shuttle may be coupled to the power track, and configured (i) to be positionable along the power track and (ii) to conduct electricity from the at least two electrical conductors to the electronic device. A box holder may be connected to the shuttle, and be configured to physically support the electronic device.

Abstract: An electronic display may include a screen including an outer perimeter and front surface. A housing may include a trim ring that surrounds the outer perimeter and extends in front of the front surface of the screen. An optical sensor shield may be is positioned at least in part in front of the front surface of the screen. An optical sensor may be disposed between the optical sensor shield and the screen to reduce the ability for ambient light to illuminate the optical sensor.

Abstract: A display device has a spring-biased pusher carried on an elongate track. A sample carrier may be located at a front end of the track. A number of such tracks and pushers may be arrayed side-by-side with one or more pitch(es) corresponding to the products being displayed in a number of columns or lanes associated with each track and pusher. The sample carrier may include a principal portion unitarily formed with the track and one or more additional portions securable thereto to retain the sample.

Abstract: A system and method for supporting and providing electrical power to devices. One embodiment includes an elongated member coupled to the structure and configured to support a device and to supply electrical power to the device. A coupling member is operable to engage the elongated member or power bus and support the device. The coupling member is operable to be moved from a first position to a second position along the elongated member to reposition the device with respect to the structure. In one embodiment, the elongated member is configured to supply electrical power to the device substantially continuously during movement of the coupling member along the elongated member.

Abstract: A display device has a spring-biased pusher (20) carried on an elongate track (24). A sample carrier may be located at a front end of the track. A number of such tracks and pushers may be arrayed side-by-side with one or more pitch(es) corresponding to the products (500) being displayed in a number of columns or lanes (510-A-510-N) associated with each track and pusher. The sample carrier may include a principal portion (220) unitarily formed with the track and one or more additional portions (250;272) securable thereto to retain the sample (236).
