  • Publication number: 20220280060
    Abstract: An electromagnetic tracking (EMT) system is configured for determining a frequency for generating at least a portion of a magnetic field signal using a transmitter coil of a plurality of transmitter coils. The EMT system configures a time-division multiplexed (TDM) control signal configured to cause the transmitter coil to transmit bursts of the magnetic field signal at the frequency. The EMT system configures a filter for filtering the TDM control signal, the filter configured to shape each burst to reduce or eliminate a harmonic artifact of the bursts. The EMT system causes the transmitter coil to generate the shaped bursts of the magnetic field signal. The EMT system receives, from a sensor, a sensor signal that corresponds to the magnetic field signal, the sensor including the output response indicative of the location of the sensor relative to the transmitter.

  • Patent number: 7511611
    Abstract: One embodiment of the present invention includes an identification mechanism, such as a radio frequency identification (RFID) tag or barcode, associated with a waste container. The identification mechanism contains an identifier that can be used to identify the waste container, and that can be read by a vehicle with an identification reader. In addition, the location of the waste container can be determined using a GPS receiver. The waste container identifier and its corresponding location can then be stored in a computer for later transmission to a second computer, for example, by using a wireless communication link. The second can be used to associate the waste container identifier and the waste container's position with a customer.
