Abstract: An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station to a receiving station. Each of the stations has a control counter each of which toggles between a logic 0 and 1. The control counter for the transmitter and the receiver are phase locked so that all errors may be corrected. The receiver echoes each data bit back to the transmitter which compares the echoed data to the transmitted data. If there is a match, the transmission was successful. If there is no match, the data must be retransmitted. A retransmit control character RTXx is sent to indicate that the receiver should discard the previous character and prepare for a retransmission of the character having the error. Under the proper circumstances and if the counters are still phase locked, the receiver then discards the previously stored character and inverts the counter.

Abstract: The present invention is for a method for correcting errors in received data during transmission of infrared radiation from a transmitter to a receiver without retransmitting entire packets. The method includes the steps of detecting an error in received data. A negative acknowledgement signal is transmitted from the receiver to the transmitter. A predetermined acknowledgement is transmitted by the transmitter to indicate to the receiver that the negative acknowledgement signal has been received. The data is then retransmitted.The data is transmitted using pulse position modulation. An error is detected by either sensing two pulses within one cycle or sensing no pulses within one cycle.The negative acknowledgement signal comprises transmitting a pulse several positions in duration. The predetermined acknowledgement by the transmitter includes purposely transmitting a cycle containing a known error.

Abstract: The present invention is for a radiation transmitter which transmits radiation to an illumination spot for forming reflected radiation. The transmitter includes a plurality of radiation transmission sources. Each of the sources transmits to a portion of the illumination spot. The transmitter includes means for alternately activating a portion of the transmission sources to illuminate a portion of the illumination spot for aligning a radiation receiver to receive the reflected radiation.Each resident of network transmits in turn its address and the address of each resident that it recognizes. Once a prospective resident can recognize each resident of the network it announces that it is joining the network and states its new address and the address of each resident it can see. Every resident then amends its list of recognized residents to include the new member.

Abstract: The present invention is an apparatus for wireless communications of information between two locations. A transmitter means modulates the information into infrared radiation at a first location. The infrared radiation is transmitted by the transmitter to a reflecting surface along a straight line path which is transparent to the infrared radiation. The infrared radiation is reflected at the reflecting surface forming reflected infrared radiation. A receiver means for receiving the reflected infrared radiation from the reflecting surface is positioned at a second location. The second location and the reflecting surface have a straight line path therebetween which is transparent to the infrared radiation.
