Underwater Sensor Apparatus

View page
US Patent:
8272262, Sep 25, 2012
Filed:
Mar 4, 2011
Appl. No.:
13/041046
Inventors:
Ramon Cabrera - Miami FL, US
Zhivko Grozev - San Diego CA, US
Alexander Kovachev - San Diego CA, US
Daryl B. Slocum - La Mesa CA, US
Adam Jackson - San Diego CA, US
Daniel Osiecki - Asheville NC, US
Assignee:
YSI Incorporated - Yellow Springs OH
International Classification:
G01C 13/00
US Classification:
7317029, 7317033
Abstract:
An underwater sensor device comprises a submersible housing including one or more housing components, one or more sensors for monitoring and collecting water characteristics, a controller for controlling operations of the one or more sensors and an graphical user interface mounted to the housing that displays the water environmental data. The housing defines a channel that extends through one of the housing components, and at least one of the sensors is mounted to the housing and extends into the channel. The controller is disposed within the housing and is operatively connected to the one or more sensors.

Multi-Frequency, Multi-Beam Acoustic Doppler System

US Patent:
8411530, Apr 2, 2013
Filed:
Dec 16, 2009
Appl. No.:
12/639989
Inventors:
Daryl B. Slocum - La Mesa CA, US
Ramon Cabrera - Miami FL, US
Zhivko Grozev - San Diego CA, US
Alexander Kovachev - San Diego CA, US
Assignee:
YSI Incorporated - Yellow Springs OH
International Classification:
G01S 15/00
US Classification:
367 90
Abstract:
An acoustic Doppler system including an acoustic subsystem controller operatively connected to a plurality of acoustic transceivers, with a first of the plurality of acoustic transceivers, operating at a first acoustic frequency, operatively connected to a first group of at least one transducer, and a second of the plurality of acoustic transceivers, operating at a second acoustic frequency, operatively connected to a second group of at least one transducer, where the acoustic subsystem controller includes a digital circuit configured to sample analog signals received from the first and second groups of transducer in pairs having a pair-wise sampling frequency that is four times the operating frequency of associated acoustic transceiver. Also presented is a method of sampling acoustic Doppler signals received from such devices, with samples comprising a pair of values taken with a pair-wise sampling frequency that is four times the operating frequency of associated acoustic transceivers, and the resulting pairs of values being further processed as representative values of the cosine and sine components of a Doppler-shift signal.

US Patent:
20110075518, Mar 31, 2011
Filed:
Sep 24, 2010
Appl. No.:
12/890505
Inventors:
Craig Huhta - Fort Collins CO, US
Ramon Cabrera - Miami FL, US
Zhivko Grozev - San Diego CA, US
Alexander Kovachev - San Diego CA, US
John Sloat - Chula Vista CA, US
Daryl B. Slocum - La Mesa CA, US
International Classification:
G01S 15/58
US Classification:
367 90
Abstract:
An acoustic Doppler system comprising a plurality of acoustic transceivers, an acoustic subsystem controller and a main processing unit operatively connected to the acoustic subsystem controller. A first of the plurality of acoustic transceivers operates at a first acoustic frequency and is operatively connected to a first group of transducers producing an acoustic signal. A second of the plurality of acoustic transceivers operates at a second acoustic frequency and is operatively connected to a second group of transducers producing an acoustic signal. The first and second acoustic transceivers are adapted to operate concurrently at the first and second acoustic frequencies. The acoustic subsystem controller is operatively connected to the first and second acoustic transceivers and controls the acoustic signals produced by the first and second group of transducers. The main processing unit is adapted to execute instructions to the first and second group of transducers to produce acoustic signals having at least two frequencies and is adapted to run at least two processing methods concurrently. The main processing unit analyzes data received by the first and second group of transducers, automatically adjusts the acoustic frequencies of the acoustic signals produced by the first and second group of transducers, and automatically selects a method of processing the data received by the first and second group of transducers.
