Abstract: One embodiment of an unmanned carrier for carrying urban manned vehicles includes a computer, a motorized lift, an autonomous-driving control system, and a safety frame. The computer synchronizes pick-up of manned vehicles by the unmanned carrier; wherein each manned vehicle is an autonomous on-road vehicle that transports one or more occupants in a compartment, is authorized by law to drive in a residential neighborhood, and is unauthorized by law to drive on the highway on its own because it is not safe enough for highway speed. The motorized lift enables the manned vehicles to get on and get off the unmanned carrier without human intervention. The autonomous-driving control system navigates the unmanned carrier autonomously on a highway. And the safety frame protects the occupants who sit in the carried manned vehicles during a collision at highway speed.

Abstract: Detecting a respiratory tract infection (RTI) based on changes in coughing sounds, which can provide an early warning of infection with a disease like COVID-19, as well as indications of its progression and severity. In one embodiment, the system includes smartglasses, with sensors mounted thereto, which include an acoustic sensor mounted at a fixed position relative to a user's head, and a movement sensor. A computer receives current measurements of the user, taken with the sensors, while there were head movements that characterize coughing, and also earlier measurements of the user, taken with the sensors, while the user had a known extent of the RTI and while there were head movements that characterize coughing. The computer detects a change relative to the known extent of the RTI based on a difference between the current measurements and the earlier measurements.

In another embodiment, a processor instructs the display module to project video responsive to an indication that the head piece and the stiff module are connected, and instructs the display module not to project the video, responsive to an indication that the head piece and the stiff module are not connected.

Abstract: Described herein are embodiments of systems and a method for affective response-based user authentication. In one embodiment, a computer receives a model that was trained with data that includes: (i) temporal windows of token instances (TWOTIs) to which the user was exposed, and (ii) affective responses of the user to the TWOTIs. The computer also receives a temporal window of token instances (TWOTI) and an affective response of the user to being exposed to the TWOTI (e.g., as measured by a sensor, such as a heart rate sensor). The computer utilizes the model to calculate a predicted affective response of the user to exposure to the TWOTI, and then calculates a similarity between the affective response and the predicted affective response. The computer sends a notification indicative of the user having an affective response that is incompatible with the model, responsive to the similarity being below a threshold.

In one embodiment, an HMD includes a display module and a mount that includes a first piece and a second piece connected by a lock. The mount attaches the display module to a passenger's head while the pieces are connected. Upon receiving an indication of an imminent collision involving the vehicle, the lock disconnects the pieces such that the first piece stays on the head shortly after the disconnection, and the second piece is removed together with the display module from the head shortly after the disconnection.

Abstract: A light shading module is integrated with a vehicle window and is configured to be in different states that involve different values of Visible Light Transmittance (VLT) of the vehicle window. A camera fixed to the vehicle takes video of the outside environment. A computer generates a video see-through (VST) of the outside environment, which is presented to the vehicle's occupant on an augmented reality device (ARD). In order to improve the image quality, the ARD operates according to different modes involving varying intensities, depending on the VLT of the window.

Abstract: Disclosed herein are systems and methods for detecting a physiological response using different types of photoplethysmography sensors. Examples of physiological responses that may be detected include an allergic reaction, a stroke, a migraine, stress, certain emotional responses, manifestation of pain, and blood pressure. In one embodiment, a head-mounted contact photoplethysmography device measures a signal indicative of photoplethysmogram signal at a first region that includes exposed skin on a user's head (PPG signal). A camera, located more than 10 mm away from the user's head, captures images of a second region that includes exposed skin on the user's head. A computer detects the physiological response based on: (i) imaging photoplethysmogram signals (iPPG signals) recognizable in the images, and (ii) correlations between the PPG signal and the iPPG signals.

Abstract: Systems and methods for detecting an occurrence of a transient ischemic attack (TIA). In one embodiment, a device is utilized to measure first and second signals indicative of photoplethysmogram signals at first and second regions on the left and right sides of a user's head (PPGSL and PPGSR, respectively). A computer detects the occurrence of a TIA based on PPGSL and PPGSR that exhibit a pattern that involves the following: (i) an asymmetry between PPGSL and PPGSR, which is below a threshold, during a first period spanning more than a day; (ii) an asymmetry between PPGSL and PPGSR, which exceeds the threshold, during a second period following the first period and spanning between 5 and 180 minutes; and (iii) an asymmetry between PPGSL and PPGSR, which falls below the threshold, during a third period following the second period.

Abstract: Some aspects of this disclosure include systems, methods, and/or computer programs that may be used to filter measurements of affective response collected using sensors that measure physiological signals and/or behavioral cues of users. A bias may be tendency, attitude, and/or inclination, which may influence the affective response a user has to an experience. Some embodiments described herein involve learning a model of biases of the user from measurements of affective response of the user and descriptions of events to which the measurements correspond. The model may be used to filter measurements of the user, which may be provided to other entities, if the model indicates that the measurements are likely to contain a certain level and/or type of bias (e.g., bias to certain factors). Such a filtration process can help make results generated based on the measurements more accurate and also may help protect the privacy of the user.
