Abstract: The invention offers an ultracapacitor-based power system solution with four main functional blocks which are power conditioning block, monitoring block, charge-discharge block and protection block. The proposed system has the advantage of working well in the environment of vibration, high temperature, has a large capacity to provide a large amount and radiates less heat compared to systems using traditional batteries. In addition, the system has functions to protect and stabilize the output voltage, and the operating parameters of the system is monitored continuously.

Abstract: A rotorcraft with counter-rotating rotor blades can hover in place, translate forwards, backwards, or side-to-side irrespective of the airspeed over the rotorcraft. The rotorcraft includes a fuselage, a first axial-flow rotor, a radial-flow rotor, a propulsion funnel, and a plurality of lift funnels. The fuselage is used to house passengers, cargo, flight electronics, and or fuel. The first axial-flow rotor rotates independent of the radial-flow rotor and generates forward thrust for propelling the rotorcraft. The radial-flow rotor in the opposite direction of the first axial-flow rotor and generates upward thrust for lifting the rotorcraft. The airflow generated by the first axial-flow rotor travels through the propulsion funnel and exits out of the back of the rotorcraft. The airflow generated by the radial-flow rotor travels through the plurality of lift funnels which gradually directs the airflow downwards.

Abstract: Device-to-device (D2D) communications between user equipment (UE) allows two UEs in a long-term evolution (LTE) network to communicate directly with each other without the need to first send their communications to a network (such as via an evolved node B). In order to communicate in a D2D mode, the UEs first need to discover each other. One method of allowing the UEs to discover each other involves the use of a physical uplink control channel (PUCCH). After a network determines that certain UEs would benefit from D2D communication, the UEs can be set up to send and receive discovery signals using the PUCCH.

Abstract: An orbiter launch system for sending a spacecraft into orbit from the upper atmosphere. An orbiter launch assembly is connected to a launch system transporter, wherein the launch system transporter provides lift surfaces for shuttling the orbiter launch assembly and a space orbiter into the upper atmosphere. The space orbiter is slidably engaged with a plurality of stabilization rails of the orbiter launch assembly, wherein the plurality of stabilization rails guides the space orbiter along the orbiter launch assembly when the space orbiter is launched from the launch system transporter. A launching trough funnels exhaust and serves as a heat shield to protect the launch system transporter when the space orbiter is launched. The space orbiter is loaded onto the orbiter launch assembly upside down, wherein a plurality of reversible seats allows passengers to remain sitting upright.

Abstract: An apparatus for generating energy using mechanical energy and gravitational energy comprises a generator, a plurality of free wheels, a first pulling mechanism, a second pulling mechanism, and a battery. The generator and the plurality of free wheels are connected by a turbine shaft. The first pulling mechanism and the second pulling mechanism are connected to the plurality of free wheels. Each plurality of free wheels comprises a rod which oscillate forward and backward turning the plurality of free wheels. Since the turbine shaft is connected with the plurality of free wheels and the generator, the generator rotates simultaneously with the plurality of free wheels. As a result, the generator produced energy which is converted into electricity.

Abstract: A networked multimedia system comprises a plurality of workstations and at least one storage server. A signal path interconnects the workstations and the storage server. Each workstation includes video and audio reproduction capabilities, as well as video and audio capture capabilities. Any given storage server comprises a set of storage cells that operate under the direction of a storage cell manager. A storage cell may include one or more encoding and/or transcoding converters configured to convert or transform audio and video signals originating at a workstation into a form suitable for storage. A storage cell may further include one or more decoding converters configured to convert stored signals into a form suitable for audio and video signal reproduction at a workstation. Each storage cell additionally includes at least one storage device and storage device controller capable of storing, for later retrieval, signals generated by one or more converters.
