  • Patent number: 11361205
    Abstract: A key fob duplication device is disclosed. The duplication device may have a housing and a display device attached to the housing. The duplication device may also have a controller enclosed within the housing. The controller may read data stored in the first key fob. The controller may also determine whether the first key fob can be duplicated based on the data. When the data indicates that the first key fob can be duplicated, the controller may write the data of the first key fob and an indicator value on a second key fob. The indicator value may indicate that the second key fob cannot be duplicated. When, however, the data indicates that the first key fob cannot be duplicated, the controller may display a message on the display device, indicating that the first key fob cannot be duplicated.

  • Patent number: 10560806
    Abstract: A method includes moving an interrogation device through multiple geographical positions. At each geographical position of the interrogation device, a wireless communication terminal is solicited to establish temporary communication with the interrogation device, and a distance value indicative of a distance between the wireless communication terminal and the interrogation device as well as a velocity of the interrogation device is estimated using the temporary communication. A geographical location of the wireless communication terminal is calculated based on multiple estimated distance values and velocities of the interrogation device corresponding to the respective multiple geographical positions of the interrogation device.

  • Patent number: 10305606
    Abstract: Communication between a wireless base-station and a microwave reflector link are enhanced by feeding back a portion of the transmitter signal, adjusted for phase and amplitude, to cancel ambient reflection blocker signals being received at the base-station. The microwave reflector link does not utilize a transmitter gain stage, but communicates data back to the base-station in response to modulating the reflections of its antenna (e.g., in gain and/or phase). The disclosure aids in the proper amplification and processing of reflection signals from the microwave reflector link, by canceling out the blocking signals which arise as background objects reflect transmitter signal energy back to the base-station.

  • Patent number: 10297914
    Abstract: An apparatus and method for enhancing full-duplex radio communications using an indented transmitter and receiver antenna. A multi-element antenna array is configured with each antenna coupled to a circulator that has connections to both a transmission path and a receiving path. The apparatus is configured with indentations that provide a tilting of the array from its broadside to create a progressive phase delay between adjacent pairs of elements. Transmitted and received waves travel a single trip through the indention, while antenna reflection or circulator leakage travels a round trip through indention, so that these signal components can be readily separated to achieve high levels of isolation during full-duplex transmitting and receiving.

  • Patent number: 10256672
    Abstract: A first power receiving apparatus observes a power transfer signal from a power supply apparatus, and detects whether power transfer is being performed between the power supply apparatus and a second power receiving apparatus. When the power transfer is being performed between the power supply apparatus and the second power receiving apparatus, a waveform of the signal is deformed with a predetermined pattern. The second power receiving apparatus detects deterioration in power which is received from the power supply apparatus and detects whether the waveform of the signal changes with the predetermined pattern within a predetermined time after detecting the power deterioration. When detecting the change in the waveform of the signal with the predetermined pattern, the second power receiving apparatus determines that the first power receiving apparatus is in a power suppliable range of the power supply apparatus.

  • Patent number: 10237000
    Abstract: A method for compensating phase shift is provided. The method includes sweeping a transmitter (TX) clock frequency over a frequency range and sampling resistance values at a receiver (RX) circuit while sweeping the TX clock frequency. A first frequency in the frequency range is determined which corresponds to a maximum resistance value sampled at the RX circuit. Using a look-up table (LUT), a phase adjust value is determined based on the first frequency. A phase of the TX clock is adjusted based on the phase adjust value.
