Appl. No.:

09/858310

John R. Lackner - San Jose CA
Mark D. Russell - Hollister CA

Assignee:

Media Arts Group, Inc. - Morgan Hill CA

International Classification:

D06C 308

US Classification:

381024, 38102, 3810291

Abstract:

A method includes steps for modifying tensile stresses in an unpainted canvas that is mounted on a frame under applied tensile stresses. The canvas is formed of material that can undergo heat-shrinking when at or above a thermoplastic shrinking temperature, and can undergo heat-softening when at or above a thermoplastic softening temperature. The method includes heating the canvas to a temperature at or above the thermoplastic shrinking temperature and the thermoplastic softening temperature. The method further includes maintaining the canvas at a temperature at or above the thermoplastic shrinking and softening temperatures. This induces heat-shrinking, and thereby increases the tensile stresses in any portions of the canvas in which the applied tensile stresses are less than the opposing stresses of the heat-shrinking. This also induces heat-softening, and thereby decreases the tensile stress in any portions of the canvas in which the applied tensile stresses are greater than the opposing stresses of the heat-shrinking. The method further includes subsequently cooling the canvas to a temperature below the thermoplastic shrinking and softening temperatures, whereby the canvas becomes set in a condition of modified tensile stresses.

Abstract:

In one embodiment, a communicating device (e.g., either a ground station server or a particular distributed module of a satellite communication system) mitigates congestion on a particular return communication path via an intermediate satellite from the plurality of distributed modules to the ground station server. In particular, in response to determining that the level of congestion is above a threshold, then the communication device mitigates the congestion by, e.g., one or both of either a) determining an uncongested return communication path from a particular distributed module to the ground station server, ensuring that the uncongested return communication path would not interfere with any unintended receiver, and then causing the particular distributed module to use the uncongested return communication path, and b) enforcing one or more communication restrictions on a utilized return communication path to reduce the effect of a communication on the overall congestion of the utilized return communication path.

Abstract:

In one embodiment, a ground station server of a satellite communication system mitigates congestion on a particular forward communication path via an intermediate satellite from the ground station server to a plurality of distributed modules. In particular, in response to determining that the level of congestion is above a threshold, then the ground station server mitigates the congestion by, e.g., determining uncongested forward communication paths, scheduling a sufficient amount of communication over the uncongested forward communication paths to alleviate congestion on the particular forward communication path without congesting the one or more uncongested forward communication paths, transmitting instructions on the particular forward communication path to corresponding modules of the plurality of distributed modules, the instructions causing the corresponding modules to use a respective uncongested forward communication path, and communicating to the corresponding modules on their respective uncongested forward communication path.

International Classification:

H04W 16/24
H04L 29/06
H04W 4/02

Abstract:

In one embodiment, a terminal of a first wireless communication network determines a protection zone for each of a plurality of unintended receivers of a second wireless communication network, where a protection zone defines a geographical area where transmission by the terminal might interfere with operation of a corresponding unintended receive. At the time of an attempted transmission, the terminal determines its current location, and whether the current location is within any protection zone of the plurality of unintended receivers. If not within any protection zone of the plurality of unintended receivers, the terminal performs the transmission, but if so, then the terminal may then perform a local assessment of interference to the one or more unintended receivers. Once concluding that there would be no interference with any of the one or more unintended receivers, the terminal may then perform the transmission. Otherwise, the terminal prevents the transmission.

Abstract:

In one embodiment, the techniques herein provide a fully automated satellite-based backhaul system. In particular, a system in accordance with the techniques herein may utilize a satellite communication terminal to allow an Internet of Things (IoT) device (or any device) to be deployed in any location which has a line of sight towards a communication satellite. Specifically, the placement, orientation, and/or communication characteristics of the IoT device and/or satellite communication terminal (or antenna) may be manipulated (e.g., manual adjustment based on calculated directions and/or completely autonomously) to ensure avoidance of interference in any other wireless communication network.

H04W 64/00

Abstract:

In one embodiment, a server of a first wireless communication network receives a wireless communication originated by a terminal of the first wireless communication network, the wireless communication containing a current geographic location of the terminal as determined by the terminal. The server may then determine acceptable communication parameters for the terminal to communicate on the first wireless communication network, e.g., based on preventing transmission by the terminal that might interfere with operation of one or more unintended receivers. The server then generates an instruction message for the terminal based on the acceptable communication parameters, and transmits the instruction message toward the terminal to cause the terminal to only continue transmitting according to acceptable communication parameters.

Abstract:

In one embodiment, a device of a first wireless communication network determines a link budget from a terminal in the first communication network to an unintended receiver for a communication from the terminal to an intended receiver in the first wireless communication network, based on the communication being configured with initial communication parameters. The device also determines whether one or more adjusted communication parameters would result in reducing a received power at the unintended receiver being below a link budget threshold, while still satisfying a receive sensitivity of the intended receiver. If so, the device causes the terminal to transmit the communication using the adjusted communication parameters. In one embodiment, the device is the terminal, and causing comprises transmitting as the terminal. In another embodiment, the device is a server of the first communication network, and causing comprises instructing the terminal to transmit the communication using the adjusted communication parameters.
