Abstract
A telemetry system is described including a remote unit having a remote input unit coupled to a remote transmit unit. The remote input unit receives one or more sensor output signals and produces a sensor status signal dependent upon the sensor output signals. The sensor status signal alternates between a first state and a second state, wherein an amount of time the sensor status signal remains in the first state is dependent upon one of the sensor output signals. An amount of time the sensor status signal remains in the second state may depend upon sensor output signals from other sensors. The remote transmit unit receives the sensor status signal and transmits a transmit signal each time the sensor status signal transitions between the first and second states. The transmit signal may be a frequency modulated radio frequency carrier signal including a status portion having direction information indicating a direction of the transition between the first and second states. The transmit signal may also have an identification portion including identification information uniquely identifying the remote unit. The telemetry system may also include a base unit coupled to receive the transmit signals transmitted by the remote transmit unit, wherein the base unit is configured to reproduce the sensor status signal from the transmit signals. The base unit may also produce a sensor status from the sensor status signal, and may display the sensor status.
