  • Patent number: 10922947
    Abstract: A ship includes a controller that performs wireless communications with a portable machine possessed by a passenger and a lanyard stop switch. When a lanyard code coupled to the passenger is pulled out, the lanyard stop switch operates to stop an engine of an outboard motor and stop the ship. When the controller detects that the lanyard stop switch operates, that is, detects a possibility that the passenger has fallen overboard, the controller starts wireless communications with the portable machine. The controller determines whether or not a rescue signal needs to be transmitted in accordance with conditions regarding a power density and a frequency of a radio wave of the wireless communications as predetermined conditions for estimating a situation of the passenger.

  • Patent number: 10852357
    Abstract: A system and method is disclosed for analyzing a set of collected raw data point values and determining which one or ones of the values are erroneous data values. In one implementation of the method specific ones of the values are examined to determine if they are outliers, and if so they are removed from the data set. At least two other ones of the values obtained at points in time prior to a given one of the values are examined. Weights may be assigned to the at least two other values, and the weights used to help generate a predicted data point value. The predicted data point value is compared to the given one of the values to determine if the given one of the values is an erroneous value. In this way the integrity of each data point value in the set can be checked.

  • Patent number: 10284305
    Abstract: Systems and methods are disclosed allowing for spatially separated nodes to transmit data to a single remote master receiver node in a synchronized way. Slave nodes can send acoustic data so that it travels through water and arrives at the master node exactly timed so that the data bit appears in a predetermined time slot. The next time slot could be a data bit coming from another remote or slave node in another direction and at a different distance. This can be repeated for many nodes and the incoming bits will be received in a time division multiplexed fashion at the receiver or master node. The senders address and bit meaning are implicit due to the time slot in which they arrive. The assumption is that all nodes have accurate synchronized time as well as the ability to accurately estimate sound travel time between itself and any master node.

A plot of acoustic intensity as a function of frequency versus time is generated from the acoustic data. A first waveguide invariant density distribution for the first frequency regime and a second waveguide-invariant density distribution for the second frequency regime is generated from the plot using curve detection. Whether the noise source is located below the thermocline is classified based on the first and second waveguide-invariant density distributions.

  • Patent number: 9829575
    Abstract: A sensor system detects objects in an environment ahead of a vehicle. The environment is represented by a predetermined fixed number of position points in an environment model. Initially and when no objects are detected, the position points may be distributed stochastically over the detection area of the sensor system. When objects are detected, the position points are re-distributed based on the detected objects, e.g. with a higher density of position points to represent the detected objects. Because the total number of position points is a predefined fixed number that remains constant, the processing, storage and transmission of the environment model involves a constant data volume and efficient use of memory and transmission bandwidth.

  • Patent number: 9244295
    Abstract: An optical modulator includes a plurality of electrode pads arranged in a zigzag alignment; two arms which are partially bent to circumvent the electrode pads so as to carry out optical phase modulation at various parts based on voltages input via the electrode pads; an optical branch structure branching the arms; and an optical coupling structure aggregating the arms together. Each arm is made of a silicon-base electro-optic element including a substrate; a first conductive semiconductor layer having a rib waveguide structure; a dielectric layer deposited on the rib waveguide structure; and a second conductive semiconductor layer deposited on the dielectric layer. The first conductive semiconductor layer is connected to first electrode wires via first contacts, while the second conductive semiconductor layer is connected to second electrode wires via second contacts. Thus, it is possible to miniaturize the optical modulator which can operate at a low voltage.

  • Patent number: 9225883
    Abstract: A hermetically sealed digital electronic camera that is designed to operate both on land and underwater to great depths, and method of making same. The present invention is a camera which is hermetically sealed by being totally encapsulated, preferably by being cast in plastic, with no seals, holes, joints, penetrating pins, wires or other objects. Wireless means are used for communicating information, electrical power and control signals. The invention is impervious to atmospheric contamination and absolutely incapable of leaking under water to great depths and pressures. In an alternate embodiment camera optics are not encapsulated but are immersed in water when the encapsulated digital camera is placed in water.

  • Patent number: 9057738
    Abstract: A typical inventive device is self-contained and is designed for adjunctive placement at the unconnected end of a towed body in order to test dynamic motions of the towed body. The inventive device includes an IMU, a computer, wired/wireless communication electronics, a fluid-dynamically shaped member, and a cylindrical housing (which encloses the IMU, the computer, and the communication electronics). The housing is connected to the towed body aft of the towed body, and the shaped member is connected to the housing aft of the housing. Data is acquired that is indicative of the inertial dynamics of the towed body while in motion through a fluidic medium. Differently shaped members can be independently connected to the housing at different times, each influencing in its own way the inertial dynamics of the towed body and yielding its own set of data. Comparisons can thus be drawn between/among differently shaped members.

  • Patent number: 9042946
    Abstract: An underwater communication device (100) is provided with a voice interface (4), a transceiving unit, a voice quality converting unit and a body (1), etcetera. A bone conduction/throat microphone unit, assembled in the voice interface (4), converts the vocal cord vibrations of a diver to voice signals. The voice quality converting unit converts the voice signals to voice signals based on a clearer voice. A transmitting unit, assembled in the transceiving unit, transmits the converted voice signals to the outside. A receiving unit, assembled in the transceiving unit, receives voice data which is transmitted from the outside. A bone-conduction speaker unit, assembled in the voice interface (4), outputs vibrations corresponding to the voice data received by the receiving unit. Attachment equipment (1, 2, 3) are put on a diver in a state where the bone-conduction speaker unit is in attached to the diver. The receiving unit and the bone-conduction speaker unit are integrally attached to the body (1).

  • Publication number: 20150098306
    Abstract: A method of acoustic depth determination in shallow water. At least one standard acoustic sensor located below an ocean thermocline is provided. The at least one acoustic sensor operates at a first frequency regime and at a second frequency regime. The first frequency regime is above a cut-off frequency. The second frequency regime is below the cut-off frequency. Acoustic data from a moving broadband noise source is recorded at the at least one acoustic sensor. A plot of acoustic intensity as a function of frequency versus time is generated from the acoustic data. A first waveguide invariant density distribution for the first frequency regime and a second waveguide-invariant density distribution for the second frequency regime is generated from the plot using curve detection. Whether the noise source is located below the thermocline is classified based on the first and second waveguide-invariant density distributions.
