Abstract: A system and method are disclosed for monitoring rides in a vehicle in which a driver of the vehicle picks up a rider at a pickup location and drives the rider to a drop-off destination. The system includes at least one sensor arranged in the vehicle and configured to capture sensor data during the rides, a transceiver configured to communicate with a personal electronic device of a driver of the vehicle, a non-volatile memory configured to store data; and a processor. The system captures sensor data during a ride, receives a ride identifier from the personal electronic device that uniquely identifies the ride, and stores the sensor data captured during the ride with the ride identifier as metadata.

Abstract: A system for rotating sound provides for the ability of the apparent direction of sound sources in a listening environment to remain in consistent orientations in space despite rotations of the microphones used to capture the sound and despite rotations of the head of the listener, even when wearing headphones. Modules are provided in the system to distinguish the sound sources and their apparent directions, as well as to rotate the sound sources in response to detected rotations of the listener's head and/or detected rotations of the microphones.

Abstract: A system for enabling a user to navigate a graphical user interface by touching pads on a touch surface. The arrangement of the pads on the touch surface is static, but the functions associated with each pad dynamically change in correspondence with functions in the graphical user interface. The functions are automatically and dynamically extracted from the software that creates the window display. Certain pads are regularly used for certain user options found in windows.

Abstract: A rotation angle sensor has a fluid-filled container which houses a vane immersed in the fluid. The vane which rotates freely with respect to the container. The container is fixedly attached to a body for which rotation angle measurement is desired. When the body, and therefore container rotates, the fluid, and therefore vane tend to remain fixed with respect tot he rotation. The angle of rotation can therefore be measured by determining the amount the container has rotated with respect to the vane.
