Patents by Inventor Plamen Vanchev

Plamen Vanchev 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).

  • Publication number: 20210329454
    Abstract: Systems and methods detect a potential hacking attack by monitoring the number and timing of DELBA (Delete Block Acknowledgement) action frames. When the number and timing of the DELBA action frames correspond to an unauthorized access pattern, an unauthorized access is detected. The potential unauthorized access may be detected by an access point (AP) or by the AP and a backend system. When a potential unauthorized access is detected, the AP may remain in silent mode for a longer period of time and limit access to the network to only trusted devices. In addition, an alarm or other notification of the potential unauthorized access may be provided to a user or other designated contact.

  • Publication number: 20200366401
    Abstract: An RF front end may determine a RF energy ratio between environmental RF energy and a jamming signal. An RF energy analysis engine may implement an adaptive AGC processing to adjust a jamming signal level to perform a jamming operation on a target RF signal based on a relationship between the RF energy ratio and a threshold.

  • Patent number: 10565840
    Abstract: Events are generated by a security controller. Video confirmation of the events is routed via a wireline broadband connection to conserve bandwidth in a cellular network. However, when the wireline broadband connection is unavailable, video confirmation of alarms may be routed into a cellular network for processing. Video associated with benign events may be stored until the wireline broadband connection is restored.

  • Patent number: 10439860
    Abstract: Concepts and technologies are disclosed herein for an installation location noise floor evaluation device. The device can be configured to receive a radio frequency signal emitted by a radio frequency device that emits a radio frequency signal that can enter into an installation location and detect a radio frequency noise floor associated with the installation location based on the radio frequency signal. The installation location noise floor evaluation device can compare the radio frequency noise floor to a noise floor threshold associated with an operating frequency of a device, generating an indication that indicates an outcome of the comparing, and output the indicator.

  • Patent number: 10242559
    Abstract: Concepts and technologies are disclosed herein for limiting service availability when a sensor device is non-operational due to a noise floor change. According to one aspect of the concepts and technologies disclosed herein, a connected home system includes a controller device configured to monitor a plurality of sensor devices deployed within a premises, and a sensor device of the plurality of sensor devices. The sensor device can monitor radio frequency (“RF”) noise in a radio environment associated with the premises. The radio environment is associated with an RF noise floor. The sensor device can determine whether the radio frequency noise exceeds a noise threshold. In response to determining that the RF noise exceeds the noise threshold, the sensor device can cause the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold.
