Ford Motor Co se pregătesc să elaboreze în comun
transmisii de vehicule cu 9 si 10 viteze pentru a le ajuta
să îndeplinească viitoarele standarde ale economiei de
combustibil. Desi nici unul nu a făcut încă un anunţ
oficial, cei doi giganti auto au semnat un memorandum
de înţelegere care să le permită să lucreze în cooperare
pe transmisii care ar putea fi gata pentru producţia încă
din 2015.
Robot broasca testoasa va înota autonom - Am văzut
un ton robotizat şi roboţi care inoata mai mult sau mai
puţin ca oamenii. Acum, inginerii de la Institutul Federal
Elvetian de Tehnologie au construit un robot modelat ca
o broască ţestoasă.
Robotul cel mai recent al Toyota dă o mână - Toyota
a dezvoltat un nou asistent personal robotizat, care poate
ajuta persoanele în vârstă sau alte persoane cu mobilitate
limitată, care ar putea avea nevoie de o mână
suplimentara pentru a face lucrurile în jurul casei.
Senzori de miscare a mainii ar putea ajuta Inginerii
Mecatronisti - Un anunţ recent de la o companie care
este specializata in senzori utilizati pentru detectarea
miscarii mainii a stârnit gânduri despre folosirea acestui
tip de control în dispozitivele mecatronice. Compania a
menţionat utilizarea controlerelor de miscare a mainii în
instalatii TV. Acest tip de control funcţionează de
asemenea pentru jocuri interactive.

International Visibility / Vizibilitate internationala
Currently researchers of National Institute of Research
and Development in Mechatronics and Measurement
Technique INCDMTM are working on a POSCCE A2-
O2.1.2-2009-2 project, contract 131 / 04.06.2010 –
INTELLIGENT AND INFORMATIONAL
DEVICES FOR MEASURING AND MONITORING
THE HYDRODYNAMICS OF THE SEDIMENTS
BASED ON NEW MEASURING METHODS –
SEDCONTROL. Director of this project is Prof. Boeriu
from IHE Delft.
INTRODUCTION
The importance of reservoirs, as water management
instruments, is detailed presented by Bătucă and Jordaan
in [1], their main functions being: power generation,
flood control, water supply, discharge regulations, level
regulations, fishing, navigation and recreation. From
exploitation reasons, it is necessary to have accurate
information about water depth and quality. Mathematical
aspects, experimental results and specific measurement
devices are presented by Van Rijn in [2] in 2006,
considering the following methods for accurate
measuring of bed level detection: mechanical bed level
detection in combination with DGPS (differential GPS),
acoustic bed level detectors (single and multi beam echo
sounders) and optical bed level detection. It is well
known [3] that “due to the particles of different sizes of
sand, silt and other materials transported in water, the
deposition of the incoming sediments starts from the
head of the reservoir and progressively extends towards
the downstream of the reservoir”. In [4], Boeriu et al.
show by the aid of complex simulations that this
simplified model becomes more complex due to the
lateral influx of water. Furthermore, the sediment
distribution is not uniform as expected along the border
of the reservoir. The limits of mathematical simulations
lead to necesity of direct measurement of water depth.
SEDCONTROL system performs measurements in fixed
points, being more accurate than a moving system like a
sonar placed on a ship, as it was stated more widely in
[5].
Description of the SEDCONTROL System
SEDCONTROL system (Figure 1) is composed of three
modules, as follows:

INTRODUCERE
Importanţa lacurilor de acumulare, ca instrumente de
gestionare a apei, este detaliat prezentată de Bătucă şi
Jordaan în [1], funcţiile principale ale acestora fiind:
producerea de energie, controlul inundaţiilor,
aprovizionarea cu apă, regimul de descărcare, reglarea
nivelului, de pescuit, de navigaţie şi de recreere. Din
motive de exploatare, este necesar să se dispună de
informaţii exacte cu privire la adâncimea şi calitatea
apei. Aspectele matematice, rezultatele experimentale şi
dispozitivele specifice de măsurare sunt prezentate de
către Van Rijn, în [2], în 2006, luând în considerare
următoarele metode de măsurare precisă de detectare a
nivelului de pat: detecţie mecanică a nivelului în
combinaţie cu DGPS (GPS diferenţial), detectoare
acustice de nivel mic (single şi multi fascicol) şi
detectoare optice. Este bine cunoscut [3], care "din cauza
particulelor de diferite dimensiuni de nisip, nămol şi alte
materiale transportate în apă, depunerea sedimentelor
porneşte de la coada lacului şi se extinde progresiv spre
aval". În [4], Boeriu et al. arată cu ajutorul unor simulări
complexe că acest model simplificat devine mai complex
datorită afluxului lateral de apă. În plus, distribuţia
sedimentelor nu este uniformă cum era de asteptat de-a
lungul malurilor lacului. Limitele simulărilor matematice
duc la necesitate de măsurare directă a adâncimii apei.
Sistemul de SEDCONTROL efectuează măsurători în
puncte fixe, fiind mult mai precis decât un sistem în
mişcare cum ar fi un sonar plasat pe o navă, aşa cum a
fost arătat mai pe larg în [5].
Descrierea sistemului SEDCONTROL Sistemul SEDCONTROL (figura 1) este compus din trei
module, după cum urmează:
1. Modulul subacvatic (dreapta jos)
2. Modulul plutitor (dreapta sus)
3. Modulul recepţie date (stânga sus)
Primele două module sunt conectate printr-un cablu de
ancorare cu lungimea de 18 m.

Figure 1: Overview SEDCONTROL system identifying those three modules / Privire de ansamblu SEDCONTROL, cu identificarea celor trei
module
The three modules are described below:
1. Underwater Module is placed at the bottom of the
lake and consists in:
- The sensorial system
- The support for the sensorial system, including the
anchor
SEDCONTROL system is designed to stay located on
the lake bottom and can be equipped with various
sensors to provide an accurate picture of the parameters
of interest. In a minimal configuration, the sensorial
system includes an ultrasonic sensor for distance
measurement and a turbidity sensor. They are fixed on a
frame made of aluminum profiles, manufactured by
Bosch, which is placed on a platform specially shaped
with anchoring function, as shown in Figure 2.
Cele trei module sunt descrise mai jos:
1 Modulul subacvatic se amplasează pe fundul lacului
de acumulare şi se compune din:
- sistemul senzorial
- cadrul suport pentru sistemul senzorial
- elementul de ancorare
Sistemul SEDCONTROL este astfel conceput încât pe
cadrul suport amplasat pe fundul lacului de acumulare se
pot amplasa diverşi senzori care să ofere o imagine cât
mai exactă a parametrilor de interes. Într-o configuraţie
minimală, sistemul senzorial conţine un senzor ultrasonic
de măsurare a distanţei şi un senzor de turbiditate.
Aceştia sunt fixaţi pe un cadru realizat din profile de
aluminiu produse de firma Bosch, care la rândul său este
amplasat pe o platformă de formă specială, care are
funcţie de ancorare, după cum se observă în fig. 2.

2. Floating Module. Because radio waves attenuate
rapidly in water, underwater emission - reception
equipment work in ultrasound field or in infrasound field
for log distances. These devices are not appropriate for
SEDCONTROL system because the signal has to be
retransmitted on the ground station. For this reason the
solution that has been chosen was to build an
intermediate floating module located at the water surface
above the underwater module.
3. Data receiver module. Data receiver module includes
a radio modem located on a support made of Bosch
profiles, a cable RS232 communicating with the field
laptop. On it is installed the acquisition, processing and
2. Modulul plutitor. Deoarece undele radio se atenuează
rapid în apă, echipamentele de emisie - recepţie wireless
subacvatic se bazează pe unde din domeniul
ultrasunetelor, iar la distanţe mari din domeniul
infrasunetelor. În plus, atât emitorul, cât şi receptorul
sunt imersate în apă, ceea ce complică lucrurile privind
recepţia datelor la sol. Din acest motiv s-a ales soluţia
construirii unui modul intermediar plutitor (a unei balize)
plasat la suprafaţa apei, deasupra modulului subacvatic
3. Modulul de recepţie date. Modulul de recepţie date
cuprinde modemul radio pereche al celui amplasat pe
modulul plutitor, fixat pe un suport realizat din profile
Bosch, modem care comunică prin cablu tip RS232 cu

data presentation software. An application allows
changing the measurements sampling rate (their
frequency).
The distance measurement subsystem consists in an
ultrasonic sensor vertically downwards oriented, placed
at the end of a horizontal arm; it is mounted at a certain
distance from the anchor to minimize disturbance in
sediment bed. The piezoelectric crystal, electrically
excited in a certain way, emits a sound wave in
ultrasonic range, which is reflected by the sediment bed
and meets after a while the piezoelectric crystal,
producing an electrical signal; knowing the wave
propagation speed in that environment, the distance
between sensor and bed sediment is then calculated wit a
resolution of about 1 cm, having thus an image of
sediments variations. It was used an ultrasonic sensor
produced by RESON / Denmark of TC2024 type -
Figure 3 [6]. In Figure 4 and 5 are shown the horizontal
directivity pattern and the receiving sensitivity.
laptopul de teren. Pe acesta se află instalate programele
de achiziţie, prelucrare şi prezentare date. Programul
aplicativ permite modificarea ratei de eşantionare a
măsurătorilor (frecvenţei acestora).
Subsistemul de măsurare a distanţei constă într-un senzor
ultrasonic orientat vertical în jos şi este montat pe un braţ
orizontal la o anumită distanţă faţă de punctul de
ancorare pentru a diminua perturbaţiile în înălţimea
patului de sedimente introduse de sistemul de măsurare;
senzorul ultrasonic se bazează pe un cristal piezoelectric
care excitat electric într-un anumit fel, emite o undă
acustică în domeniul ultrasonic; această undă este
reflectată de patul de sedimente şi întâlneşte după un
anumit timp cristalul piezoelectric, producând un semnal
electric; cunoscând viteza de propagare a undei în mediul
respectiv se determină distanţa dintre elementul
ultrasonic fix şi patul de sedimente cu o rezoluţie de cca.
1 cm, rezultând evoluţia acestuia în timp; Senzorul
ultrasonic de distanţă este produs de firma RESON din
Danemarca şi este de tipul TC2024 - fig. 3 şi are
directivitatea frontului de undă ca în fig. 4. În fig. 5 este
prezentată sensibilitatea la recepţie.

rivers and lakes; further has a sensor to measure water
temperature and one for measuring hydrostatic pressure.
It also contains the power and signal conditioning,
analog digital converter and a data storage device and is
accompanied by processing, presenting and
interpretation software of the data.
