Abstract: Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The method can include detecting the actual value of the coefficient of friction (e.g., between a tire and the ground), updating the coefficient of friction during braking using the braking torque data derived from at least one braking pad of each wheel, and adjusting brake force. For example, the brake force can be adjusted as a function of and/or to be approximately equal to the value of the actual tire-road friction during braking. Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The ...more ...less

Abstract: A system, a method and instructions embodied on a non-transitory computer-readable storage medium that solve a 3D point-in-polygon (PIP) problem is presented. This system projects polygons that comprise a set of polyhedra onto projected polygons in a reference plane. Next, the system projects a data point onto the reference plane, and performs a 2D PIP operation in the reference plane to determine which projected polygons the projected data point falls into. For each projected polygon the projected data point falls into, the system performs a 3D crossing number operation by counting intersections between a ray projected from the corresponding data point in a direction orthogonal to the reference plane and polyhedral faces corresponding to projected polygons, to identify polyhedra the data point falls into. The system then generates a visual representation of the set of polyhedra, wherein each polyhedron is affected by data points that fall into it. A system, a method and instructions embodied on a non-transitory computer-readable storage medium that solve a 3D point-in-polygon (PIP) problem is presented. This system projects polygons that comprise a set of polyhedra onto projected polygons in a reference plane. Next, the ...more ...less

Abstract: A computing system is described that obtains, based at least in part on information included in at least one previous communication associated with a user of a computing device, an indication of a future location and a future time and event information associated with the future location and the future time. The computing system obtains a duration of time for the user to travel from a current location of the computing device to the future location, and, based at least in part on the duration of time, obtains a departure time at which the user is predicted to need to depart from the current location in order to arrive at the future location by an arrival time based on the event. The computing system outputs, for transmission to the computing device, an indication associated with the event and including information indicative of the departure time. A computing system is described that obtains, based at least in part on information included in at least one previous communication associated with a user of a computing device, an indication of a future location and a future time and event information associated with the future ...more ...less

Abstract: A method is disclosed for incorporating preferences of a human occupant into an autonomous driving experience. The method may include a computer system autonomously controlling speed and steering of a vehicle. While it is controlling the vehicle, the computer system may interpret a speech command received from a human occupant of the vehicle. The computer system may determine whether changing at least one of the speed and steering in accordance with the speech command would be safe and legal. If it would be safe and legal, the computer system may change the at least one of the speed and steering in accordance with the speech command. If it would not be safe and legal, the computer system may leave the at least one of the speed and steering unchanged in contravention of the speech command.
