Suresha Chandrasekhara has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11891839
    Abstract: An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.
    Type: Grant

  • Publication number: 20220275666
    Abstract: An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

  • Patent number: 11274470
    Abstract: An exemplary trim assembly comprises a housing assembly, a cam rotatably mounted to the housing assembly, a lift finger slidably mounted in the housing assembly such that the cam is operable to linearly drive the lift finger between a deactuated position and an actuated position, and a locking mechanism operable to selectively retain the lift finger in the deactuated position. The locking mechanism includes an interface member engaged with the lift finger such that movement of the lift finger moves the interface member between a home position and an offset position, a blocking member operable to selectively prevent movement of the interface member from the home position, and a driver configured to move the blocking member between a blocking position and an unblocking position to thereby lock and unlock the trim assembly.
