Injection-locked laser system
A method and system for injection-locking multiple optical amplifiers is disclosed. A master laser is employed to generate a continuous-wave output field. Optical modulators then produce first and second seed optical fields from the continuous-wave output field. The first and second seed optical fields provide an input to injection lock one or more optical amplifiers, optionally at different operating frequencies. Since the first and second seed optical fields are generated from the continuous-wave output field then the output fields of the optical amplifiers exhibit a high phase-coherence with each other and with the continuous-wave output field. Employing the first and second optical fields reduces the requirement to induce large frequency shifts on a single optical field. Techniques for phase-locking the output of the injection-locked laser systems are also provided to further reduce phase noise within the systems. |

Warehouse automated cart priority notifications
Disclosed are systems and methods for monitoring operations of autonomous vehicles within a warehouse. The autonomous vehicle's processing unit may detect when the autonomous vehicle is delayed based on one or more timers or time thresholds, such as an amount of time that the autonomous vehicle has been located at a particular location or the amount of time between when the autonomous vehicle received product picking instructions and a shipping deadline. The autonomous vehicle may also use various types of data to detect potential problems, such as determining an amount remaining battery life. Once the autonomous vehicle identified a particular triggering condition, then the autonomous vehicle may trigger an annunciator (e.g., flashing lights, sounding horn) or transmit a notification to other devices, such as client devices. The annunciators or notifications attempt to capture personnel attention to resolve the identifier problem. |
