Patent number: 9013060Abstract: A system and method for measuring, monitoring and controlling electrical power directed through one or more electricity directing devices is provided. The one or more electricity directing devices includes electrical sockets supplying power to one or more devices. The system includes a potential transformer configured to receive AC voltage directed through a socket and further configured to relay the voltage to a processing device. The system further includes a current sensor configured to sense current drawn from the socket and further configured to relay the current to the processing device. A microcontroller is adapted to receive analog or digital values of voltage and current corresponding to AC voltage and AC current. The microcontroller then measures values of voltage and current, calculate electrical power consumed and generate a control signal. The control signal activates a switching device operationally connected to the socket and switches power flow through the socket.Type: GrantFiled: June 14, 2010Date of Patent: April 21, 2015Assignee: Infosys LimitedInventors: Siva Prasad Katru, Kumar Padmanabh, Sanjoy Paul

Patent number: 8886736Abstract: A method for communicating with one or more sensor nodes in a Wireless Sensor Network (WSN) over a network is disclosed. The method includes initiating communication with the sensor nodes by sending messages to the server application using the instant messaging system. The server application formats the received messages and communicates to the sensor nodes and in turn also receives responses from the sensor nodes and communicates them back to the IM client. The method also includes steps for enabling a WSN messaging client to converse with an instant messaging client over the network during communication with the one or more sensor nodes in the WSN. The method further includes identifying the IM client the user has employed for communication and the corresponding IM protocol. Also, the method includes the step of configuring the WSN messaging client with the same IM protocol to enable communication.Type: GrantFiled: April 5, 2012Date of Patent: November 11, 2014Assignee: Infosys LimitedInventors: Adi Mallikarjuna Reddy Vanteddu, Siva Prasad Katru, Kumar Padmanabh

Patent number: 8743198Abstract: A method for detecting occupancy status of a plurality of conference rooms in real time is provided. The method enables, firstly, monitoring a first output signal of a first sensor. Secondly, the method enables monitoring a second output signal of a second sensor. The method further enables comparing the first and second output signals with one or more predetermined thresholds within a predetermined time. Furthermore, the method enables correlating the comparison results to identify any uncertainty in detecting the occupancy. Furthermore, the method enables processing output from one or more image and/or video sensors based on the correlation to obtain occupancy status information when there is uncertainty in detecting occupancy. Finally, the method enables displaying the occupancy status information on one or more user devices.Type: GrantFiled: March 1, 2010Date of Patent: June 3, 2014Assignee: Infosys LimitedInventors: Kumar Padmanabh, Sanjoy Paul

Patent number: 8659865Abstract: An electrical circuit for protecting an electrical load from overload current is provided. The system includes a voltage transformer configured to receive AC mains voltage from an electric mains supply and further configured to apply reduced voltage to the electrical load. A control switch comprising metal contacts is connected to the voltage transformer. The control switch is configured to facilitate application of reduced value of AC mains voltage to the electrical load. A reduced value of current flowing through the electrical load is measured by a current transformer connected in series with the electrical load. The reduced value of current is then used for estimating a current consumption value in event of AC mains voltage being directly applied to the electrical load. A control signal is then used for disconnecting the electrical circuit if the estimated current consumption value is greater than threshold overload current value.Type: GrantFiled: March 28, 2011Date of Patent: February 25, 2014Assignee: Infosys LimitedInventors: Kumar Padmanabh, Sai Pawan Kumar Chevuru, Sanjoy Paul
