Abstract: A system for identifying one or more product engagements includes one or more microsensors configured to measure one or more signals indicative of one or more near-product engagements within a retail environment. Near-product engagements product movement, customer proximity to products, temperature, and the like. In some embodiments, the system may be configured to generate spatial relationship data associated with one or more spatial relationships between one or more transmitting electronic devices and one or more sensor units. The system may perform one or more filtering steps on the near-product engagement or spatial relationship data and providing the filtered data to a user interface.

Abstract: An energy transmission and control system includes a power supply, a conductive support to electrically couple to the power supply, and a vehicle to electrically couple to the conductive support to receive electrical energy from the power supply. The conductive support can be configured to support the vehicle for travel along the conductive support and to transmit the electrical energy from the power supply to the vehicle. The electrical circuit can be configured to transmit a communications signal at a low frequency of about five hundred kilohertz or less. The vehicle can include a translating contact for electrically coupling the vehicle to the conductive support, a switch for selectively transmitting the electrical energy from the power supply to an electrically powered element or subsystem, and a controller to receive the communications signal and operate the switch to selectively transmit the electrical energy to the electrically powered element or subsystem.
