  • Publication number: 20190239116
    Abstract: Embodiments herein describe wireless transmission techniques for mitigating interference between wirelessly controlled machines in a shared space. To mitigate interference, the machines may be assigned different channels within the same frequency band. However, if machines using the same channel in a frequency band receive each other's wireless signals, the wireless signals can interfere. To free up additional bandwidth, in one embodiment, the command signals are transmitted using a different frequency band than a heartbeat signal used to stop the machines in case of emergencies. In another embodiment, time multiplexing or directional antennas can be used to mitigate interference. In another example, antenna diversity and multiple-input-multiple output (MIMO) can be used to further focus the radiation pattern onto the desired machine while avoiding transmitting wireless signals to neighboring machines. In one embodiment, the machines may use dual-channels to transmit and receive duplicate data.

  • Patent number: 10354498
    Abstract: Embodiments herein describe techniques for operating lighting systems which can be used by associates who are colorblind or are susceptible to optically induced seizures (e.g., photosensitive epilepsy). In one embodiment, the lighting system includes programmable light sources which permit the lighting system to use colors that a colorblind person can easily distinguish—e.g., red, blue, orange, etc. Put differently, the lighting system can choose colors which are easily distinguishable to a colorblind associate when instructing the associate to take an action. Moreover, the lighting system can pulse a light source by changing its brightness or intensity over time. The lighting system can control a maximum gradient change rate and a maximum intensity change to mitigate a risk of optical seizures when pulsing the light sources to mitigate the risk of inducing a seizure.
