    Abstract: Electronic education systems generally includes a central computer, a display unit, and various student terminals connected to the central computer by a data transmission network. The network transmits data to and from the central computer for analysis, the data includes students' task and their response. Such a system is relatively expensive, and is not portable. This invention provides an electronic education system for evaluating responses from a group of students to a set of multiple choice questions. Each of the questions having a maximum of x choices. The system includes at least one IR transmission device for transmitting a plurality of IR signals to a console, which includes a processor for analyzing the responses, a memory for storing the multiple choice questions and corresponding answers, output means for outputting data to a display device, and receiving means for receiving the IR signals.

    Abstract: A one-way or single-channel communication network utilizing electromagnetic radiation signals of a fixed single or narrow-band frequency in free air space consists of a plurality of transmitters and a central receiver in which each message is encoded in a wave train and is tagged with a sender identity (ID). The central receiver, which can be a single unit or a plurality of units connected in cascade, detects the messages in the free air space and send them along to a central processing unit (CPU) for message handling. Possible additional features of the system are: an option of a small display panel on the individual transmitter to show the message to be sent plus the number of attempts a message was sent within a preset time; a separate feedback segment, such as a colour change of a characteristic symbol on a central display screen visible to the sender, providing a confirmation that the message has been received; each symbol on the display screen showing the number of times a message was received from the corresponding transmitter within a present time; and a built-in option to either retain or black out the ID tag on the messages to be processed by the CPU. The free forming aspect of the system stems from the portability of the ID-encoded transmitters which enables any combination of transmitters to form a communication network, and a plurality of such combinations to form a plurality of networks.
