181 Method and mechanism for reduction of within-train reported data EP96303826.0 1996-05-29 EP0747726A2 1996-12-11 Hassan, Amer Aref; Hershey, John Erik

A tracking system for railcars is configured as a dynamic local area network having a master tracking unit and a plurality of slave tracking units, each tracking unit being affixed to a separate railcar. To improve reliability of communications between railcars, the distance from a master unit to a slave unit is estimated by comparing phase of a transmitted signal with that of the transmitted signal returned by another tracking unit in the network. Optionally, a determination is made as to whether the slave unit is "ahead" of or "behind" the master unit. Communication path loss between the master and slave units due to frequency selective fading may also be determined. A spectrum survey determines quality of the channel as to its capacity for passing data from the slave unit to the master unit.

185 Hydroacoustic ranging system EP91101777.0 1991-02-08 EP0447783A2 1991-09-25 Rouquette, Robert E.

Digital processing systems and methods of hydroacoustic pulse communications in offshore seismic exploration systems provide more efficient surveys with less critical equipment. Thus hydroacoustic transceiver transducers towed in a set of streamers behind a vessel are accurately positioned under variable operation conditions with a geodetic reference point for more efficiently and accurately monitoring echo points for seismically identifying underwater formations. Spacings between transducers are found by calculating from pulse arrival times the transit times of hydroacoustic pulses. Predetermined pulse shapes and carrier frequencies above 40kHz are accurately determined upon receipt by digitally sampling waveshapes to determine shape and timing the reception of identified pulse shapes at transducers which are transmitted from other transducers for computing separations between sending and receiving transducers. Pulse transit time averaging avoids precise synchronization for simpler apparatus. The carrier frequencies and associated high pass filters for received pulses eliminate hydroacoustic noise. The digital pulse sampling and timing techniques simplify communications with associated data processing systems for seismic analysis and provide compact on-location electronic systems coupled to the transducers.

189 Underwater work system US17590201 2022-02-01 US11964745B2 2024-04-23 Noriyuki Okaya; Koichi Fukui
An underwater work system of the present disclosure acquires a relative position of an underwater vehicle relative to a surface ship at the start of searching work, the relative position being measured based on a sound wave transmitted from a wave transmitter. The underwater work system calculates a position of the underwater vehicle based on the acquired relative position. When a measurement error region whose center corresponds to the calculated position of the underwater vehicle and an expected laid region of a pipeline extending in a predetermined direction overlap each other, the underwater work system moves the underwater vehicle to such a position that the measurement error region and the expected laid region do not overlap each other, and then, makes the underwater vehicle perform crossing detection in which the underwater vehicle detects the presence or absence of the pipeline while crossing the expected laid region.

193 SYSTEMS AND METHODS FOR CONTACT AVOIDANCE FOR PREVENTING EPIDEMICS US17228116 2021-04-12 US20210319912A1 2021-10-14 William R. Bandy; Michael R. Arneson
Embodiments described herein are directed to a contact avoidance system for preventing epidemics. A database maintains a record for each person enrolled in the system. The record comprises a risk level identifier that indicates a disease infection risk for the user. When devices carried by users are proximate to each other, the devices exchange identifiers that uniquely and anonymously identify the users. At least one device provides the identifier received thereby to the database, which retrieves the record associated with the identifier and determines a risk level for the user associated with the identifier. The risk level is returned to the device, which issues an alert if the risk level indicates that the other user is or may be infected with a disease. The database also updates the risk level associated with users that were determined to be proximate to a user determined to be infected with the disease.

197 Methods and system to assist search and interception of lost objects US15997815 2018-06-05 US10871566B2 2020-12-22 Thomas Danaher Harvey
Devices and methods for aiding a large area search for objects. A searcher transmits interrogation signals of long range relative to the return range to be received by a device at the target object. The target device responds with a ping signal modified to be more easily found by means of information contained in the interrogation signal. The information may be in the nature of the received signal or data encoded and embedded. The target device may use a microprocessor to do complex operations using the information from the interrogation signal and other information. Detection of a weak ping is facilitated by such means as being beamed in the direction of the interrogation, arriving at a predictable time, or having parameters adapted to values requested by the searcher. The object is then intercepted with help of the ping or other signals from the device.
