Abstract: A method of controlling an automatic transmission connected to an engine in a motor vehicle employs a switch for requesting selection of transmission speed-ratio ranges. According to the method, the switch receives an input signal and generates an output signal having the same duration as the input signal. A controller programmed with an engine threshold speed and a threshold signal duration receives and compares the output signal with the threshold signal duration. The controller also determines a current transmission speed-ratio range and a transmission threshold speed-ratio range that is defined by engine's threshold speed. The controller additionally commands the transmission to change the current speed-ratio range to a neighboring speed-ratio range if the signal duration is less than or equal to the threshold. Furthermore, the controller commands the transmission to change the current speed-ratio range to the threshold speed-ratio range if the signal duration is greater than the threshold.

Abstract: A system includes one or more devices for use in a learning environment that transmit information about the learning environment to a computing system. A recording device for use in the learning environment includes a camera, a processing device, and a storage device. The processing device is configured to process each of a plurality of video files including video data captured by the camera to generate information about which of the plurality of video files satisfy a particular characteristic. The recording device is configured to transmit the information about which of the plurality of video files satisfy the particular characteristic to the computing system, and is configured to transmit a particular video file of the plurality of video files in response to a download request for the particular video file. Wearable devices are wearable by students in the learning environment and transmit signals to provide information about the students.
