Abstract: Techniques for using acoustic notifications output via a multi-channel speaker configuration for pedestrian notification are described. Computing device(s) can determine a plurality of signals for dynamically emitting a plurality of sounds via a plurality of speakers associated with an acoustic array disposed on a vehicle. Each signal of the plurality of signals can be emitted from speaker(s) of the plurality of speakers that is/are associated with a particular channel of a plurality of channels. Furthermore, the computing device(s) can cause a portion of the plurality of speakers to dynamically emit the plurality of sounds so that the plurality of sounds are spatialized across the at least one surface of the vehicle. As a result, a pedestrian proximate the vehicle can localize the vehicle as a source of the acoustic notification and perceive a size, or other geometric characteristic, of the vehicle.

Abstract: A method of indicating an oxygen desaturation period has been initiated includes detecting an oxygen mask configured to supply oxygen to a patient to saturate the patient, detecting a removal of the oxygen mask from the patient to stop saturation of the patient, initiating a desaturation timer in response the removal of the oxygen mask from the patient, and operating an image display device to display a first running time on a screen of the image display device indicating a desaturation time elapsed from a time of the removal of the mask.

Abstract: Techniques for using beam-formed acoustic notifications for pedestrian notification are described. Computing device(s) can receive sensor data associated with an object in an environment of a vehicle. The computing device(s) can determine first data for emitting a first beam of acoustic energy via speaker(s) of an acoustic array associated with the vehicle, and second data for emitting a second beam of acoustic energy via speakers of the acoustic array. The computing device(s) can cause the speaker(s) to emit the first beam in a direction of the object at a first time and the second beam in the direction of the object at a second time. Directions of propagation of the first beam and the second beam are offset so that the object can localize the source the acoustic notification, thereby localizing the vehicle in the environment.

Abstract: A method of displaying information associated with an application of an intubation device includes detecting an orientation of a screen attached to the intubation device, and setting a template for displaying values of a parameter associated with one of the plurality of sensors in a display window on the screen according to the orientation of the screen. The method includes receiving data from the plurality of sensors, and continuously displaying a video image from an optical imaging device during an intubation of a patient and periodically displaying on a portion of the screen a display window including a value of the parameter according to the data received instead of a part of the video image. Setting the template includes setting a frequency of display, a size, or a color for the parameter.

Abstract: A metal laryngoscope blade is provided for use in a laryngoscope including a laryngoscope handle to form an operative generally L-shaped configuration. The blade comprises a metal laryngoscope spatula having a longitudinal centerline, a proximate end and a distal end correspondingly adjacent to and remote from the laryngoscope handle in the operative generally L-shaped configuration, a top surface and a bottom surface correspondingly facing away from and towards the laryngoscope handle in the operative generally L-shaped configuration. The distal end has a leading safety tip contact zone including a front edge and opposite leading side edges meeting the front edge at leading corners. The blade further comprises a non-metal safety tip mounted on said distal end to embed said safety tip contact zone therein.
