Abstract: Systems and methods of tracking distribution items using hardware components on or in the distribution items. Shippers and recipients of distribution items can track or locate a distribution item, especially a high value item, if the distribution item is lost, misrouted, or delayed. Distribution items can be tracked until an indication of delivery, such as at a delivery location.

Abstract: A device, system, and method for maintaining temperature control of a distribution item, or of the contents of a distribution item, as the distribution item moves through the distribution network. A container housing an item can include a cooling unit, a heating unit, or both, and control circuitry including a temperature sensor. The control circuitry activates the cooling unit or heating unit as required to maintain the item at a desired temperature or within a desired temperature range.

Abstract: A method of inventory management is described. Upon activation of a button on a wireless device, the wireless device having a light source and a transceiver with a unique media address corresponding to a unique product, the device broadcasts a first signal including an order command and the unique media address by the transceiver via a wireless medium. A central controller then receives the first signal, identifies the unique media address included in the first signal, and using a database, identifies the unique product associated with the unique media address.

Abstract: A transponder and sensor apparatus with on-board power supply is mounted in or on a vehicle tire. A pressure sensor, a temperature sensor and a tire rotation sensor are mounted in a housing along with the transponder, the power supply and an antenna. Upon receiving an interrogation signal from a remote interrogator, the transponder activates the sensors to sense tire pressure and temperature and then backscatter-modulates the radio frequency signal from the interrogator with the tire condition parameter data from the sensors to return the backscatter modulated signal to the interrogator.
