Abstract: A method includes identifying, using at least one processing device, a time period in which a first user is online and available based on the first user's schedule. The method also includes identifying, using the at least one processing device, one or more second users who are online and available, where the one or more second users are remote from the first user. The method further includes sending, using the at least one processing device, invitations to the first and second users. In addition, the method includes, in response to at least two of the users accepting the invitations, initiating, using the at least one processing device, a communication session between the at least two users.

Abstract: A method includes transmitting a first electromagnetic signal from a first node to a second node through free space. The method also includes transmitting a second electromagnetic signal from the first node to the second node through a communication link, where the communication link physically couples the first and second nodes. The method further includes identifying a distance between the first and second nodes based on a time-difference-of-arrival between reception of the first electromagnetic signal at the second node and reception of the second electromagnetic signal at the second node.

Abstract: A method includes transmitting a first electromagnetic signal from a first node to a second node and receiving a second electromagnetic signal from the second node at the first node. The method also includes repeating the transmission of the first electromagnetic signal and the reception of the second electromagnetic signal multiple times. The method further includes identifying, based on the repeated transmissions and receptions, a time-of-flight associated with a travel time for one of the electromagnetic signals to travel between the first and second nodes. The time-of-flight is indicative of a distance between the nodes.

Abstract: A method includes receiving electromagnetic signals containing pulses. The method also includes converting the pulses contained in the electromagnetic signals into an electrical signal that identifies at least some of leading or trailing edges of the pulses. The method further includes repeatedly (i) accumulating the electrical signal to generate a voltage using an integrating circuit and (ii) resetting the integrating circuit in response to the voltage of the integrating circuit meeting or exceeding a threshold voltage. In addition, the method includes providing a count value identifying a number of times that the voltage of the integrating circuit meets or exceeds the threshold voltage. Each time the voltage of the integrating circuit meets or exceeds the threshold voltage is representative of a specific number of pulses received in the electromagnetic signals.

Abstract: A method includes communicating first and second signals between a first node and a second node, where the first signal includes a sonic signal and the second signal includes an electromagnetic signal. The method also includes using the electromagnetic signal to one of start or stop a timer and using the sonic signal to another of stop or start the timer. The method further includes identifying a one-way time-of-flight associated with the sonic signal traveling between the first and second nodes using the timer. The one-way time-of-flight associated with the sonic signal is indicative of a distance between the nodes.

Abstract: Covert acoustic communications (CAC) through solid propagation channels that connect node pairs is achieved by encoding signals using spread spectrum coding techniques that position the encoded signal at a center frequency fc within a narrow frequency bandwidth BWNB in which the amplitude of the channel response H(f) between each node pair is relatively high. The channel response H(f), bandwidth BWNB and center frequency fc, and accordingly the signal data rate will adapt for each node pair and possibly each side of the node pair. A pre-distortion filter 1/H(f) pre-distorts the encoded signal over bandwidth BWNB to compensate for material and modal dispersion and multipath between the node pair. This technique avoids the problems associated with frequency dependent attenuation of the continuous solid path and allows for simultaneous transmission and reception of signals among the multiple node pairs.

Abstract: Technology for determining a point-to-point separation between a first ship (e.g., guide ship) and a second ship (e.g., following ship) is disclosed. One approach can include maritime autonomous station keeping (MASK) interactive device comprising a communication module and a processor. The communication module can be configured to receive a following ship reference point (SRP) generated by at least one differential global positioning system (DGPS) receiver on a following ship relative to a guide SRP generated by at least one DGPS receiver on a guide ship. The processor can be configured to generate a plurality of fixed following reference edge points (REPs) relative to the following SRP representing a following ship hull, generate a plurality of fixed guide REPs relative to the guide SRP representing a guide ship hull, and monitor a plurality of distances between the plurality of following REPs and the plurality of guide REPs.
