摘要:
A data communication device includes both a two-way communications component having a first receiver and transmitter, and a second receiver. The second receiver activates the two-way communications component from a dormant state upon receipt by the second receiver of a wake-up broadcast that includes a wake-up identifier of the data communication device. A method of providing information via the second receiver—which information is auxiliary to the wake-up of the two-way communications component—includes transmitting a wake-up broadcast capable of being received by the second receiver. The wake-up broadcast includes a data construct including a wake-up identifier and the auxiliary information. The wake-up identifier may or may not be a wake-up identifier of the data communication device. Nevertheless, the auxiliary information is received and recorded by the data communication device via the second receiver with the two-way communications component remaining in the dormant state.

A method of securing a container includes inserting, into a seal device at a container, an electronic bolt; reading, by the seal device, a serial number stored in the electronic bolt; communicating, from the seal device, to a user application, insertion of the bolt; scanning, by the user via a handheld device, a barcode on the seal device representative of an identification of the seal device; communicating, from the handheld device to the user application, the identification of the seal device; inputting, by a user at the container via the handheld device, information associated with the container; communicating, from the handheld device to the user application, the information associated with the container; associating, in a database by the user application, the information associated with the container with the bolt serial number and the identification of the seal device; communicating, by the user application, a confirmation to the seal device.

A method of providing network communications includes receiving, at a second device via a virtual network connection that virtualizes network capabilities of the second device, a packet transmitted by a first device, the packet including protocol information; determining a third device to which to transmit the packet, said determination being informed by the protocol information; and transmitting the packet to the third device using a virtual network connection, which virtualizes network capabilities of the second device, in accordance with the protocol information.

An all weather housing assembly for protection of electrical components includes a first housing having an open end and defining a first compartment for receipt therein of electronic components; a cover attached to the first housing for enclosing the first compartment, the cover further including a mounting structure for receiving and retaining a power source which structure is mounted on a side of the cover that is exterior to the enclosed first compartment; and a second housing having an open end and defining a second compartment that is dimensioned to cover and protect a power source when received and retained by the mounting structure of the cover, the second housing being connected to the first housing independent of the attachment of the cover to the first housing.

Each of a plurality of network nodes in an ad hoc mesh network utilizes a data communication device that includes a two-way communications component, comprising a first receiver and transmitter, and a second receiver. The second receiver activates the communications component from a dormant state when it receives a broadcast including a wake-up identifier of the communication device. A method of activating and deactivating a mesh network includes, first, transmitting a broadcast that includes a wake-up identifier such that each second receiver of each communication device identified by the wake-up identifier, upon receipt, activates the communications component of the communication device, which then engages in mesh networking communications, and, second, transmitting a second broadcast including a second identifier such that the communications component of each communication device identified by the second identifier, upon receipt, will cease its mesh networking communications and will return to the dormant state.

A method includes communicating, by a first device, a request to a server to engage in communications with a second device; communicating, by the server, the request received from the first device to the second device; communicating, by the second device, acceptance to the server; communicating information associated with a third device to the first device; using a virtual network connection of the first device, establishing network communications with the third device; communicating information associated with the third device to the second device; using a virtual network connection of the second device, establishing network communications with the third device, wherein the third device is configured to act as a switch and provide cross-connect functionality between the first virtual network connection of the first device and the second virtual network connection of the second device.

A method of reducing server overhead in responding to requests for downloads from devices includes the steps of receiving, at a first device, a communication from a server regarding a request for download that the server has received from a second device; in response thereto, using virtualized network capabilities of a virtual machine of the second device, establishing a network connection with the first device using connection information received from the server; fulfilling the request for download by transferring data via the established network connection; and communicating an indication of fulfillment of such request to the server.

A method includes detecting, at a device, a request for a network connection from an application running on the device; spawning first and second virtual machines for network connections that virtualize network capabilities of the device such that first and second virtual network connections are provided; using the first virtual network connection, establishing a first connection with another device over a first path; using the second virtual connection, establishing a second connection with the other device over a second path; determining that the second path represents a trusted path; determining that a first packet does not need to be routed via a trusted connection; transmitting the first packet using the first virtual network connection for communication via the first path; determining that a second packet needs to be routed via a trusted connection; and transmitting the second packet using the second virtual network connection for communication via the second path.
摘要:
A method of forming ad hoc RSI hierarchical communication networks among pluralities of wireless transceivers includes assigning to each of the transceivers one or more common designations. A network organization routine of the transceivers operates to establish hierarchical networks based on the transceivers' common designations, resulting in a logical network organization that provides efficiencies for acquiring information from particular transceivers that share a common designation. Each transceiver's common designation is used by a digital processor of the transceiver to selectively receive data packets that are intended for receipt by transceivers sharing the particular common designation. Such a “common designation” network reduces power consumption and signal interference thereby increasing battery life. Each transceiver may include a sensor interface a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system of information such as, for example, sensor-derived information and time-sensitive information.

In a wireless network that includes a plurality of nodes, a method of maintaining, by a first node, information regarding communications links between nodes in the wireless network includes: for each communications link that is established with another node, recording an identification of the other node; and for each message received by the first node from the other node through the communications link with the other node, recording a network pathway by which the message has been sent in the wireless network, the network pathway identifying the nodes and the communications links therebetween by which the message has been sent. Another method includes recording, by a server, for each message that is received by the server from the wireless network, a network pathway by which the message has been sent, the network pathway identifying the nodes and the communications links therebetween by which the message has been sent.
