Abstract: An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

Abstract: A radio-frequency receiver achieves high sensitivity by pumping atoms to high-azimuthal (?3) Rydberg states. A vapor cell contains quantum particles (e.g., cesium atoms). A laser system provides probe, dressing, and coupling beams to pump the quantum particles to a first Rydberg state having a high-azimuthal quantum number ?3. A local oscillator drives an electric field in the vapor cell at a local oscillator frequency, which is imposed on a distribution of quantum particles between the first Rydberg state and a second Rydberg state. An incident RF signal field interferes with the local oscillator field, imposing an oscillation in the distribution at a beat or difference frequency and, consequently, on the intensity of the probe beam. The beat frequency component of the intensity of the probe beam is detected, and the detection signal is demodulated to extract information originally in the RF signal.

Abstract: The present disclosure describes approaches to camera re-localization using a graph neural network (GNN). A re-localization model includes encoding an input image into a feature map. The model retrieves reference images from an image database of a previously scanned environment based on the feature map of the image. The model builds a graph based on the image and the reference images, wherein nodes represent the image and the reference images, and edges are defined between the nodes. The model may iteratively refine the graph through auto-aggressive edge-updating and message passing between nodes. With the graph built, the model predicts a pose of the image based on the edges of the graph. The pose may be a relative pose in relation to the reference images, or an absolute pose.
