Abstract: A rocket engine with porous structure is disclosed. The rocket engine can include an outer wall, a combustion chamber, a coolant distribution channel defined between the combustion chamber wall and the outer wall, and a manifold. The combustion chamber can have a combustion chamber wall, a first end, a second end opposite to the first end, and a nozzle section disposed at the second end. The manifold can be disposed at the first end of the combustion chamber and have an injector to direct a propellant into the combustion chamber and a coolant inlet to direct a coolant to flow through the coolant distribution channel. The combustion chamber wall can be manufactured through an additive manufacturing process and have a porous section to provide transpiration cooling to the combustion chamber from the coolant that flows through the coolant distribution channel.

Abstract: A system is provided comprising a control station for remotely controlling unmanned aerial vehicles (“UAV”). The control station is configured to display vehicle status data received from each UAV, including displaying a location of each UAV in a single interface. Through the single interface, the control station may receive a control command input associated with one of the UAVs. The control station may transmit the received control command, or a command derived therefrom, to the respective UAV. The single interface may provide for a user to view and control flight operation of each of the UAVs independently through the single interface.

Abstract: The described embodiments relate generally to methods, systems and security devices for authorizing use of a software tool. Certain embodiments of the invention relate to a security device. The security device comprises at least one communication subsystem for enabling communication between the security device and a first external device, wherein the first external device has a software tool executable on the first external device. The security device further comprises a memory and processor coupled to the at least one communication subsystem and configured to control the at least one communication subsystem. The memory is accessible to the processor and stores a key for authorizing use of the software tool. The memory further stores program instructions which, when executed by the processor, cause the processor to execute a security application.

Abstract: The present invention provides electrochemical cells and batteries having one or more electrically conductive tabs and carbon sheet current collectors, where the tabs are connected to the carbon sheet current collectors; and methods of connecting the tabs to the carbon based current collectors. In one embodiment, the electrically conductive tabs are metallic tabs.

Abstract: Techniques for registering for communications for a communications application stored in a mobile device are described. The mobile device communicates, via a communication network, a request for a connection with a private network. If the connection is established within a predetermined period of time, then the mobile device receives from the private network a first IP address for assignment to the mobile device, and communicates to a server a request for registering for the communications using the first IP address assigned to the mobile device. If the connection is not established within the predetermined period of time, then the mobile device communicates to a server a request for registering for the communications using a second IP address assigned to the mobile device.

Abstract: A wireless mobile communication device includes a first processor configured to execute a software application and a second processor configured to manage wireless communication over a wireless network. The processors are located in the same communication device and configured for one of the processors to send data to the other processor under a protocol. In accordance with this protocol, if the sending processor does not receive a receipt acknowledgement for the sent data from the other processor before the end of a resend time period measured from when the data was sent, then the sending processor resends the data to the other processor after the end of the resend time period. However, the sending processor does receive the acknowledgement before the end of the resend time period, then the sending processor does not resend the data to the other processor.

Abstract: Protection of real-time data such as voice data exchanged as packets between a mobile electronic device (10) and a VPN gateway (122) during a media session over a communications link (130) that includes a wireless network (132). A first VPN connection (136) is established between the mobile electronic device (10) and the VPN gateway (122) through the communications link (130), the first VPN connection (136) using key-based encryption to protect data exchanged therethrough. While the first VPN connection (136) is established, a second VPN connection (138) is established between the mobile electronic device (10) and the VPN gateway (122) through the communications link (130), the second VPN connection (138) using key-based encryption to protect data exchanged therethrough. Real-time data packets are exchanged between the mobile electronic device (10) and the VPN gateway (122) through the second VPN connection (138).

Abstract: In one illustrative example, a mobile communication device includes a wireless transceiver, one or more processors coupled to the wireless transceiver, memory, and a communications application stored in the memory. The communications application may be a VoIP telephony application which involves communication in accordance with a session initiation protocol (SIP).

Abstract: A system and method for adapting data for transmission to a mobile electronic device (10) in a communications system (100) that includes at least a first wireless network (110) and a second wireless network (130) having respective coverage areas wherein the mobile electronic device (10) receives data signals from a data conversion device (116) through one of the wireless networks (110, 130) based on a location of the mobile electronic device (10). Content that is destined for the mobile electronic device (10) through a selected one of the wireless networks is received at the data conversion device (116). The content is adapted at the data conversion device based on the selected wireless network (110, 130) and outputted for transmission over the selected wireless network (110, 130) to the mobile electronic device (10).

Abstract: The present invention provides a holder for a rectangular carton of the milk-type variety having a triangulated top with a forward pour spout and a rearward recess in the top opposing the pour spout. The holder itself comprises an upper and a lower set of rectangular arms, an upper tongue and a rearward handle. The arms in at least the upper set are resiliently spreadable for spreading outwardly to fit the tongue in the rearward recess in the top of the carbon and for thereafter rebounding inwardly to clamp to the front of the carton with the tongue fitted into position. The arms in the lower set may be additionally spreadable to assist in the fitting of the holder to the carton.
