Abstract: The system set forth herein relates to a network formed between an instructor device and one or more student devices where the system monitors sensors in the student devices to determine whether the student is distracted. The instructor is able to identify operating parameters for the system in the form of rules. The student devices must follow the rules, and where the system detects a rule violation, a warning may be issued to the instructor, student, or both. This allows students to have their mobile devices (such as cell phones or tablets) in class, and even use the mobile devices to participate in class, but also allows the instructor to remotely control and monitor how those student devices are being used.

Abstract: A wireless sensor probe is used for performing experiments in an interactive laboratory. The probe may include a plurality of sensors for collecting experimental data during an experiment and a transmitter for wirelessly transmitting the collected data to a receiver module. The receiver module is adapted for transferring the data to a computer where a software component may process the data for presentation of the resultant processed data on a display substantially in real-time.

Abstract: An audience response system comprising a base unit and a plurality of remote units communicating using wireless communication operating on a frequency pair. When a response key on a remote unit is activated, the remote unit transmits a voting signal packet to the base unit. The base unit registers the vote and transmits an acknowledgment signal to the remote unit. When the remote unit receives an acknowledgment signal, the remote unit certifies to the operator that the vote was received. If an acknowledgment signal is not received, the remote unit will attempt at least one retransmission after a random delay before alerting the operator that the vote attempt has failed.
