Abstract: Automatic local gateway router backup of a network gateway router is disclosed. A local gateway router communicatively coupled to a local subnet determines that a network gateway router that serves as a default gateway router for the local subnet has stopped responding. The local gateway router and the network gateway router are configured to communicate with one another via a tunnel implemented by a tunneling protocol. In response to determining that the network gateway router has stopped responding, automatically switching, by the local gateway router, from a tunneling mode to a routing mode, such that the local gateway router becomes the default gateway router for the local subnet.

Abstract: Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.

Abstract: A secure network device management system and method include monitoring and validating commands to network devices before such commands are executed. The security system accumulates inputs from a network device intended for display on a terminal and provided by the network device in response to inputs from the terminal and received by the network device. When a control input to execute the command is received from the terminal, the security system reproduces the command from the accumulated inputs and compares the reproduced command to a command list to determine whether the command is authorized. If so, the security system provides the control input to the network device such that the network device executes the command. Otherwise, the security system may delete the command and transmit an alert to the terminal.
