MONITORING SYSTEM FOR TWO-POST LIFT
First Claim
1. A vehicle lift comprising:
- a vertically-orientated column;
a pair of swing arms vertically-shiftable with respect to said column, wherein said swing arms are configured to rotate with respect to said column;
a sensor associated with each swing arm, wherein each sensor is configured to obtain information related to its respective swing arm, wherein each sensor is associated with a radio-frequency identification (RFID) tag, with said RFID tag being configured to provide power to its respective sensor; and
a system controller in communication with said sensors and configured to control said vehicle lift based on the information obtained by said sensors.

Abstract
A vehicle lift comprising a vertically-orientated column and a pair of swing arms vertically-shiftable with respect to the post. The swing arms are configured to rotate with respect to the column. The vehicle lift additionally includes a sensor associated with each swing arm. Each sensor is configured to obtain information related to its respective swing arm. Each sensor is also associated with a radio-frequency identification (RFID) tag, with the RFID tag being configured to provide power to its respective sensor. The vehicle lift further includes a system controller in communication with the sensors and configured to control the vehicle lift based on the information obtained by the sensors.

15. A method for operating a vehicle lift, with the vehicle lift including a vertically-orientated column and a pair of vertically-shiftable swing arms, wherein the swing arms are configured to rotate with respect to the column, said method comprising the steps of:
-
(a) engaging the swing arms into contact with lifting-points of a vehicle; (b) raising the vehicle; during said raising of step (b), emitting an interrogation signal to radio-frequency identification (RFID) tags in communication with sensors associated with the swing arms; (c) obtaining, via the sensors, information related to the swing arms; (d) analyzing the information obtained from the sensors to determine if a problem condition exists; and (e) upon determining the problem condition exists, halting operation of the vehicle lift. - View Dependent Claims (16, 17, 18, 19)

20. A vehicle lift system comprising:
-
at least two lifting-posts, wherein each lifting-post comprises a vertically-orientated column, a pair of swing arms vertically-shiftable with respect to said column, wherein said swing arms are configured to rotate with respect to said column about a generally horizontal plane, a sensor positioned on each of the swing arms, wherein each sensor is configured to measure a load being supported its respective swing arm, an RFID tag associated with each sensor, wherein said RFID tags are configured to provide power to said sensors and to transmit measurement data indicative of the loads measured by the sensors; and a system controller configured to receive the measurement data transmitted by the RFID tags and to control the lifting-posts based on the measurement data.
