Abstract: In some implementations, a robotic device may receive, from a first light detection and ranging (LIDAR) sensor and a second LIDAR sensor, calibration data associated with a physical environment of a robotic arm of the robotic device. The robotic device may determine, based on the calibration data, a configuration of a boundary for the robotic arm. The robotic device may position, relative to the robotic arm, the first LIDAR sensor at a first position and the second LIDAR sensor at a second position to sense an activity within the boundary. The robotic device may monitor the boundary based on first sensor data from the first LIDAR sensor and second sensor data from the second LIDAR sensor. The robotic device may disable, based on the first sensor data or the second sensor data indicating the activity associated with the boundary, the robotic arm from moving within the boundary.

Abstract: Systems and methods for detecting a state of at least one button are disclosed herein. The method detects a first signal of a headset of a user. The first signal is indicative of the headset being coupled to a device. The headset has a microphone and at least one button. The method determines, based on the detected first headset signal, a first voltage of the microphone, and sets, based on the first voltage of the microphone, a threshold voltage for detecting a state of the at least one button. The method stores the threshold voltage and determines a second voltage of the microphone. The method compares the second voltage of the microphone and the stored threshold voltage, and generates, based on the comparison, a signal indicative of a state of the at least one button.

Abstract: Methods and apparatus for aligning a lens holder in a small-height scan engine are disclosed herein. An example method for aligning a lens holder in a small-height scan engine includes: mounting an image sensor to a circuit board; optically aligning, using one or more alignment fixtures, a lens holder holding one or more lenses or optical elements with the image sensor based upon one or more images captured by the image sensor through the lens holder; and after the lens holder and image sensor are optically aligned, physically aligning, using the one or more alignment fixtures, the lens holder with the circuit board based upon a misalignment between a surface of the lens holder and an edge of the circuit board.

Abstract: A system for determining a distance between a receiver and a transmitter are disclosed herein. The transmitter includes a first antenna array having a first spatial orientation and is configured to transmit a signal. The receiver includes a second antenna array and an orientation sensor to determine a second spatial orientation of the second antenna array and is configured to receive the signal. A logic circuit is configured compare the first spatial orientation to the second spatial orientation to determine a relative orientation of the second antenna array; determine an angle of arrival of the signal; identify, based on the relative orientation of the second antenna array and the angle of arrival of the signal, a received signal strength compensation value; and calculate a distance between the transmitter and the receiver based on a measured received signal strength of the signal and the identified compensation value.

Abstract: In some implementations, a device may transmit, to an authentication server, a certificate signing request (CSR) based on a private key stored on a data logger, wherein the data logger is integrated with a sensor within the device. The device may receive, via the data logger and from the authentication server, a signed device certificate based on the CSR. Additionally, the device may receive, via the data logger and from the authentication server, a signed owner certificate associated with a controller. The device may receive, via the data logger and from the controller, a command signed using the owner certificate. Accordingly, the device may store, in the data logger, measurements from the sensor based on the command. The device may generate a data structure including the stored measurements, wherein the data structure is signed using the signed device certificate. The device may transmit, to the authentication server, the data structure.

Abstract: In some implementations, a server device may receive event-based data associated with a user device, wherein the user device is communicatively coupled with the server device via an access point within a physical environment. The server device may determine, using a model, a status of the user device that is based on the event-based data, wherein the model is configured based on historical event data associated with historical events involving a plurality of other user devices that are associated with the user device. The server device may determine, based on the status indicating that the user device has likely been abandoned within the physical environment, a location associated with the user device. The server device may perform an action associated with the user device and the location.
