    Abstract: A lighting device include a first string of light emitting diodes (LEDs) to emit a white light having a warm white Correlated Color Temperature (CCT) and a second string of LEDs. The second string of LEDs includes blue light LEDs that emit a blue light and green light LEDs that emit a green light. The lighting device further includes a tuning circuit to adjust an amount of current flowing through the second string of LEDs. The warm white light, the blue light and the green light produce a combined light, and a CCT of the combined light is tuned by adjusting the amount of current flowing through the second string of LEDs.

    Abstract: A service provider based security system of a cellular network includes a security device that is deployed in the cellular network. The security device receives and monitors cellular network traffic to identify a data packet of the cellular network traffic that is associated with a graphics protocol. Responsively, the security device creates a digital fingerprint using unique service provider specific information and/or a portion of the data packet. The security device encrypts the digital fingerprint. Further, the encrypted digital fingerprint is embedded in a header of the identified data packet and/or stored in a database coupled to the security device for further access by authorized users. Additionally, the security device determines a security action that is to be executed in association with the identified data packet.

    Abstract: A water heater has a tank defining an interior volume, a heating element disposed within the interior volume, and a temperature sensor disposed with respect to the heating element so that the temperature sensor detects temperature of an area ambient to the heating element in the interior volume. The heating element is actuated at a predetermined actuation rate and for a cumulative actuation period so that the predetermined actuation rate maintains the heating element below a predetermined maximum temperature in air and so that the actuation period contributes a predetermined amount of energy to the ambient area when the heating element is immersed in water.

    Abstract: A downhole energy transmission system is described. The system can include a tubing string having a number of tubing pipe disposed within an annulus formed by a casing string disposed within a wellbore, where the tubing string has at least one wall forming a cavity. The system can also include a remote electrical device disposed within the cavity of the tubing string at a first location. The system can further include a first stripline cable disposed on an outer surface of the tubing string, where the first stripline cable transmits a first electromagnetic directional traveling wave received from an energy source. The system can also include a second stripline cable disposed adjacent to the first stripline cable at the first location, where the second stripline cable is electrically coupled to the remote electrical device.
