The computing element outputs a heart rate and a respiration rate according to the first and second filtered signals.

Abstract: Techniques for determining a parking trajectory for an autonomous vehicle. In some examples, a vehicle may navigate to a destination within an environment. The vehicle may receive parking locations proximate the destination, and determine a cost for navigating to each parking location, or multiple locations within a parking space. Each of multiple trajectories may include desired state(s) that represent the desired state information of the vehicle at a specific locations along the trajectory. The vehicle may determine a cost for the trajectory by comparing the predicted pose of the vehicle at the parking state to the target pose of the parking location. The vehicle may follow the trajectory based on the cost.

Abstract: This invention introduces a haptic communication system designed for high-bandwidth tactile interaction by converting external signals into dynamic patterns traced on the user's skin. It comprises a flexible, fabric-like mesh with a densely packed array of compact actuators. Activated sequentially, these actuators tap the skin, creating lines or patterns for tactile communication or sensory replacement. The mesh is adaptable for integration into wearable technology or electronic device casings, suitable for applications ranging from assistive devices for sensory impairments to immersive gaming and virtual reality experiences. The actuators are arranged in an array, with a controller managing power delivery to individual actuators, triggering movement for precise haptic feedback. This system offers a method for delivering nuanced, adjustable tactile sensations, paving the way for new forms of non-visual, non-auditory communication and interaction in diverse environments.
