摘要:
Systems and methods for determining an optimal range of frequencies of electromagnetic waves are described. In some embodiments, mobile voice communications devices measure average power received from certain ranges of such frequencies, each range associated with a communications service provider. A cost may be associated with each range. An optimal range of frequencies may be determined based on these factors. Each device may also receive a set of data identifying the location of the device. Each device may transmit one or more communications signals to a CIP with such measurements and location information, and some of this information may be stored in a database.

Methods and apparatuses for accessing, via a public network, a device connected to a privately addressed network are disclosed. One method comprises the steps of automatically assigning a globally unique name to the device, which resolves to a gateway of the privately addressed network, automatically associating the globally unique name with a private address of the device, and automatically routing communications comprising the globally unique name to the device based on the private address. The name and the address of the gateway may be registered with a Domain Name System (DNS) in response to a request received from the device. If a communication comprising the globally unique name is received for the device from another device via the Internet, a private address for the device dependent on the globally unique name may be automatically obtained for automatically routing the communication to the device.

Methods, systems, and gateways are disclosed for automatically setting up a redirector of domain name system (DNS) name requests. A DNS setup packet is transmitted to a remote gateway via a tunnel of a virtual private network (VPN). The setup packet comprises a global name of a home network and a private address of a DNS server in the home network. A DNS setup reply packet is received from the remote gateway via the tunnel. The reply packet comprises a global name of another home network and a private address of a DNS server in the other home network. An application level gateway of the DNS server (DNS-ALG) in the home network is configured dependent upon the DNS setup reply packet to redirect DNS name requests for the global name of the other network to the DNS server in the other network. Methods, systems, and gateways are also disclosed for resolving a domain name request in a DNS.

This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted (556) from a first (904) and second (906) media packet stream. The extracted samples are written to a buffer (910) based on the output time of each sample (556). Extracted samples having the same output time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”, The location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.

The present disclosure is related to transmitting and receiving media channels, such as audio and video channels. These channels may be transmitted as packets from one or more transmitting devices to one or more receiving devices for playout. Certain embodiments of the present disclosure include systems, methods, and computer-readable media for determining latency of a data network for synchronized playout of received signals. Additionally, certain embodiments of the present disclosure include systems, methods, and computer-readable media for synchronizing playout among devices connected to a data network.

An assembly for attaching a first element to a second element. The assembly includes a first non-metallic connecting member. The first non-metallic connecting member includes a first member having a first surface and a second member. The second member extends substantially perpendicular from a first end adjacent the first surface to a second end and has an outer surface. Apertures in the first and second elements receive the second member.

A composite head-electrical conditioner assembly that includes a slider with a transducer head and transducer bond pads. The transducer bond pads communicate a transducer level electrical signal with the transducer head. An integrated circuit substrate has a conditioning circuit and first substrate bond pads electrically connected to the transducer bond pads. The integrated circuit substrate has second substrate bond pads with a conditioned electrical signal that is transmittable over a circuit. The slider is rigidly mounted to the integrated circuit substrate to form an assembly that is flexibly mountable. A thermal isolation space is provided between the transducer and the conditioning circuit. The integrated circuit can be in the form of a cap that provides windage reduction.
摘要:
A free space point-to-point signaling system is described in which optical beams generated by two free space transceiver units are optically aligned with each other using beam steering techniques. Once aligned, each transceiver unit detects the received signal strength and transmits this information to the other transceiver unit. This information is used by the other transceiver unit to vary the signal strength of the beam that it transmits and to optimise the alignment between the light beams transmitted by the two transceiver units. The determined received signal strength measure is also used to detect if the two transceiver units have become misaligned or if the beams have been interrupted, so that the transmission power can be reduced if necessary or so that the alignment procedure can be restarted.
