Abstract: A technique provides an amphibious, submersible vehicle, which includes an electric drive and is capable of operating both on land and in water. The vehicle includes a water-tight compartment that houses batteries and a set of electric motors for propelling the vehicle using tracks on land and on a subsea floor. The vehicle is further capable of propelling itself through water, using the tracks and/or a set of thrusters powered by the batteries.

Abstract: A firefighting vehicle includes a chassis that houses an electric drivetrain for driving wheels of the vehicle. A conduit extends within the chassis from back to front for conveying firefighting fluid. Within the chassis, a first motor and a first battery pack are disposed on a first side of the conduit and a second motor and a second battery pack are disposed on a second side of the conduit. The first motor is configured to drive a first wheel on a first side of the vehicle, and the second motor is configured to drive a second wheel on a second side of the vehicle. The conduit is configured to provide firefighting fluid to a monitor mounted at the front of the chassis, where the fluid can be discharged toward a target, such as a fire.

Abstract: Some embodiments are associated with a data center cloud computing environment executing a plurality of virtual machines. A virtual machine data store may contain information about the plurality of virtual machines associated with the cloud computing environment. A virtual machine test platform may access the information in the virtual machine data store and periodically initiate a network test for each of the plurality of virtual machines based on the information in the virtual machine data store. The virtual machine test platform may then receive network test result signals from the virtual machines in response to the executed network tests and apply, for each virtual machine, a digital signal processing noise filter to successive network test result signals from that virtual machine. An output of the digital signal processing noise filters may then be transmitted from the virtual machine test platform.

Abstract: A hairdryer including an ionizing system and a heater wherein the ionizing system comprises an ion producing electrode and the ion producing electrode extends along an external periphery of the heater. The ion producing electrode may extend along the heater to a downstream end of the heater. The ion producing electrode may extend along the heater from an upstream end of the heater. The heater may be generally cylindrical and the ion producing electrode extends along a radially outer surface of the heater. The ion producing electrode may have a first part which extends along a first axis and the first part extends along the external periphery of the heater. The ion producing electrode may have a second part, which extends along a second axis, wherein the second part extends radially inwards from the external periphery of the heater.

Abstract: A bicycle lighting system comprises a front light 13 with a power source 11 with a cradle 12 for mounting on a bicycle, said front light 13 being releasably secured to the cradle 12 to allow removal of the front light 13 when the bicycle is not being used, front light indicator lights 14A, 14B powered by the from light power source, a rear light 23 with a power source 2 for mounting on a bicycle, rear indicator lights 24A. 24B powered by the rear light power source, and a switch device 30 for mounting, on the handlebars X to operate the lights, the switch device being adapted to control the rear light and rear indicator lights through a wireless connection. Removal of the front light from its cradle may disable the rear light. The system may also include a helmet-mounted wirelessly controlled light and the power sources may be kept charged by means of a solar panel.

Abstract: An invention is disclosed for updating a networked, single-threaded application's data model without blocking the application's entire user interface. In embodiments of the invention, a client executes a networked application with a single-threaded user interface that communicates with a server to refresh its data model. The client sends a message to the server that requests a refresh of the data model. Before the data model has been refreshed, the client receives local user input to perform an action on the data model. The client sends a message to the server to cancel the refresh. When the client receives an acknowledgement from the server that the refresh has been cancelled, the client performs the action. After performing the action, the client sends a second message to the server that requests a refresh of the data model, and then refreshes the data model upon receiving the refreshed data model from the server.

Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.
