Abstract:
1. A powered awning assembly comprising: an awning frame comprising a first side arm member having a first distal end and a first proximate end for attachment to a wall, a second side arm member having a second distal end and a second proximate end for attachment to a wall, and a connecting member having a first end attached to the distal end of the first side arm and a second end attached to the distal end of the second side arm; a roll awning attached to the awning frame; a wind sensor assembly attached to one of the first side arm and the second side arm; the wind sensor assembly comprising a sensor housing comprising a housing base and a housing cover, a sensor mounting structure for removably receiving the sensor housing, a wind speed sensing zone located between the housing base and the housing cover, a first thermistor positioned within the sensing zone for measuring a temperature of wind in the sensing zone, and a second thermistor positioned within the sensing zone for sensing a cooling effect over time of wind in the sensing zone; a thermistor control circuit for heating the second thermistor to a predetermined temperature; a motor for opening an awning; a relay for selectively connecting power to the motor; a wired remote switch for opening and closing of the awning; a wireless remote control circuit for opening and closing of the awning; an ignition interlock circuit for connection to an ignition circuit of the recreational vehicle; a microprocessor for causing the relay to control the opening and closing of the awning in response to inputs received from the wired remote control and the wireless remote control circuit, wherein the microprocessor repeatedly receives input from the first thermistor and the second thermistor, repeatedly retrieves a corresponding wind speed value from a lookup table, repeatedly stores the corresponding wind speed value, repeatedly calculates a cumulative average wind speed value and automatically causes the awning to close when the cumulative average wind speed value reaches or exceeds the threshold wind speed, and wherein the microprocessor prevents the opening of the awning in response to an ignition signal received from the ignition interlock; a power supply circuit for supplying operating power to the motor, the wireless remote control circuit, the thermistor control circuit and the microprocessor; and a first sensor enable switch and a second sensor enable switch for selectively enabling and disabling the automatic closing of the awning by the microprocessor when both the first sensor enable switch and the second sensor enable switch are activated together.
