  • Publication number: 20230410027
    Abstract: The world's cargo is transported in shipping containers. Historically, there has been little visibility into cargo once it goes inside a container. Breakable cargo, such as glass, is sometimes damaged in shipping. Sensors can be used to measure shocks experienced by the container in transit. The present disclosure presents systems and methods for analyzing such shocks into shock clusters and outliers. The present disclosure also proposes a way to assign probable cause to the shocks in each cluster based on prior knowledge of shock causes. The nature of shock data presents nuances that contribute to the uniqueness of the example implementations herein.

  • Publication number: 20230410033
    Abstract: The world's cargo is transported in shipping containers. Historically, there has been little visibility into cargo once it goes inside a container. Moisture-sensitive cargo is often damaged in transportation. The present disclosure involves a system for monitoring and predicting water damage in containers. Use of this system can enable pre-emptive action to lessen damage. Specific considerations of container transportation and availability of weather data give this problem unique characteristics, distinguishing it from generic monitoring. These considerations in turn motivate the solution framework presented here.

  • Patent number: 9078270
    Abstract: Systems and methodologies are described that facilitate providing opportunistic relay node communication based on scheduling of other communications in a wireless network. In particular, a relay node can maintain a backhaul link with an access point and an access link with a mobile device to facilitate communicating information therebetween. Time slots during which the backhaul link is active can be determined and avoided during scheduling access link communications with the mobile device. Furthermore, resource assignments from the access point to the mobile device can be monitored and decoded such that time slots associated therewith can also be determined and avoided. Thus, the relay node can communicate with mobile devices in time slots where the backhaul link is inactive and/or the mobile devices are not occupied communicating directly with the access point.

  • Patent number: 8798526
    Abstract: Techniques for selecting and processing signals from different stations in a wireless network are described. A destination station may receive a direct signal from a source station and at least one relay signal from at least one relay station. The destination station may determine metrics for the source and relay stations, e.g., based on pilots received from these stations. The destination station may select at least one signal to process from among the direct and relay signals based on the metrics for the source and relay stations. The destination station may select the direct signal if the metric for the source station exceeds a threshold. The destination station may select the relay signal from each relay station having a metric exceeding at least one threshold. The destination station may process the at least one selected signal to recover a transmission sent by the source station to the destination station.

  • Patent number: 8774119
    Abstract: Providing for fair resource sharing among wireless nodes in a wireless communication environment is described herein. By way of example, fairness can comprise establishing a set of resource sharing credits for wireless nodes. By expending credits, a node can borrow a resource of another node, to enable or enhance operation of the borrowing node. Credits for the borrowing node are decreased based on consumption of a shared resource, or credits for the lending node are increased based on such consumption, or both. Once an amount of credits expires, a node can be restricted from borrowing further resources until enough resources are lent to build up a suitable amount of credits. Accordingly, fairness can comprise correlating shared resource consumption with shared resource provisioning, to encourage participation in cooperative wireless communications.

  • Patent number: 7821980
    Abstract: A method including transmitting a binary vector from a source node to a relay node and receiving a signal vector at the relay node. The method also includes compressing the signal at the relay node by multiplying the signal with a matrix using probabilities and converting output probabilities from the multiplying into retransmission signal amplitudes, the signal amplitude depending not only on a probability of a bit but on a transmission power constraint at the relay node. The method also includes transmitting, by the relay node, estimates of information from the source node to a destination node.

  • Publication number: 20090325479
    Abstract: Providing for distributed processing for a set of wireless communication devices to implement distributed, multi-antenna communication via one or more of the devices is described herein. By way of example, a relay link can be established between one or more wireless transceivers. The link can be utilized to distribute an indexing parameter to a remote transceiver. The indexing parameter can be employed to identify a set of index-specific instructions configured for a particular wireless node of a network. Based on the instructions and indexing parameter, such transceiver can locally compute and transmit, or receive and decode, a stream of traffic data for the multi-antenna communication. Thus, for instance, a P-P link between UTs can be employed to implement increased throughput and reduced interference benefits of multi-antenna communication for unplanned configurations of mobile devices.
