1. A method of receiving signals of multiple types, the method comprising:
- at a vehicle;
receiving a first signal, the first signal being of an ASK-compliant modulation type;
receiving a second signal, the second signal being of a FSK-compliant modulation type;
based upon a set of predetermined criteria, selecting one of the first signal and the second signal, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK compliant communications;
transmitting the selected signal data to a vehicular controller over a single transmission line;
wherein the predetermined criteria comprise at least one of;
whether a received low priority frame is an actual low priority frame rather than a reflection;
whether the actual low priority frame is being recreated; and
whether a valid high priority frame is being received;
selectively storing one of the high priority frame and the low priority frame in a buffer, wherein selectively storing comprises choosing between at least two of completely storing, partially storing, and not storing;
recreating a frame, at least partially, at a faster data rate than the data rate at which the frame was received.

Abstract
At a vehicle, a first signal is received and the first signal is of an ASK-compliant modulation type. A second signal is received and the second signal is of a FSK-compliant modulation type. Based upon a set of predetermined criteria, one of the first signal and the second signal is selected, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK-compliant communications. The selected signal is transmitted to a vehicular controller over a single transmission line.

7. An apparatus configured to receiving signals of multiple types, the apparatus comprising:
-
an interface having an input and an output, the interface configured to receive a first signal at the input, the first signal being of a ASK-compliant modulation type and further configured to receive a second signal at the input, the second signal being of a FSK-compliant modulation type; and a controller comprising a microcontroller, the controller coupled to the interface, the controller configured to, based upon a set of predetermined criteria, select one of the first signal and the second signal, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK compliant communications and to issue a control signal at the output that is effective to transmit the selected signal data to an external vehicular controller over a single transmission line; wherein the predetermined criteria comprise at least one of whether a received low priority frame is an actual low priority frame rather than a reflection; whether the actual low priority frame is being recreated; and
whether a valid high priority frame is being received;
the controller further configured to selectively store one of the high priority frame and the low priority frame in a buffer, wherein selectively storing comprises choosing between at least two of completely storing, partially storing, and not storing;recreating a frame, at least partially, at a faster data rate than the data rate at which the frame was received. - View Dependent Claims (8, 9, 10, 11, 12, 19, 20, 22)

13. A computer usable non-transitory medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method of receiving signals of multiple types, the method comprising:
at a vehicle; receiving a first signal, the first signal being of an ASK-compliant modulation type; receiving a second signal, the second signal being of a FSK-compliant modulation type; based upon a set of predetermined criteria, selecting one of the first signal and the second signal, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK compliant communications; transmitting the selected signal data to a vehicular controller over a single transmission line; wherein the predetermined criteria comprise at least one of; whether a received low priority frame is an actual low priority frame rather than a reflection; whether the actual low priority frame is being recreated; and
whether a valid high priority frame is being received;selectively storing one of the high priority frame and the low priority frame in a buffer, wherein selectively storing comprises choosing between at least two of completely storing, partially storing, and not storing; recreating a frame, at least partially, at a faster data rate than the data rate at which the frame was received. - View Dependent Claims (14, 15, 16, 17, 18, 23)
