Provided are methods for autonomous vehicle and audio user guidance, which can include detecting user input at a first surface, determining context data associated with a feature of the first surface and providing an instruction associated with the context data. Systems and computer program products are also provided.

Autonomous vehicle with audio user guidance

Display screen or portion thereof with graphical user interface

Among other things, techniques are described for screening and monitoring the health of a vehicle user including receiving sensor data produced by a sensor at the vehicle, processing the sensor data to determine at least one health condition of the user of the vehicle, and in response to determining the at least one health condition, executing a vehicle function selected from a plurality of vehicle functions based on the at least one health condition.

Passenger health screening and monitoring

Methods, apparatus, and systems for passenger authentication and entry for autonomous vehicles are disclosed. A vehicle receives information over a first communication channel from a first mobile device. The information specifies a geographical location. The information causes the vehicle to arrive at the geographical location. The vehicle transmits a first message to a second mobile device indicating that the vehicle has arrived at the geographical location. The first message includes a graphical icon representing the vehicle. The graphical icon is for display on a user interface of the second mobile device. The vehicle receives a second message from the second mobile device over a second communication channel. The second message indicates that the graphical icon was dragged across the user interface into a graphical receptacle displayed on the user interface. Responsive to receiving the second message, at least one door of the vehicle is unlocked.

Passenger authentication and entry for autonomous vehicles

A solid state electronic spin system contains electronic spins disposed within a solid state lattice and coupled to an electronic spin bath and a nuclear spin bath, where the electronic spin bath composed of electronic spin impurities and the nuclear spin bath composed of nuclear spin impurities. The concentration of nuclear spin impurities in the nuclear spin bath is controlled to a value chosen so as to allow the nuclear spin impurities to effect a suppression of spin fluctuations and spin decoherence caused by the electronic spin bath. Sensing devices such as magnetic field detectors can exploit such a spin bath suppression effect, by applying optical radiation to the electronic spins for initialization and readout, and applying RF pulses to dynamically decouple the electronic spins from the electronic spin bath and the nuclear spin bath.

Use of nuclear spin impurities to suppress electronic spin fluctuations and decoherence in composite solid-state spin systems

Long spin coherence lifetimes are realized for ensembles of electronic spin impurities in solid state spin systems, for example NV color centers in diamond, by using spin-control RF pulse sequences to provide dynamic decoupling of the ensembles of spin impurities from environmental sources of decoherence such as dipolar and hyperfine interactions with proximal spin and other paramagnetic impurities in diamond. In this way, the measurement sensitivity of the coherent evolution of ensembles of solid state spin impurities are increased. Using the Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence, the spin coherence lifetimes of NV ensembles can be extended to more than 2 ms in room temperature diamond, and sensitivity of magnetometry that uses NV ensembles can be increased.
