Light up some scented candles to add a classy touch. Here are some good suggestions. Its not attractive. Slide your hand onto the bend of her waist. Instead, just be yourself, nerves and all. Use your favourite cleanser,toner and moisturizer. Only put a bit on, you don't want to over-do it! If he mentions specific traits or qualities that he likes, such as a girl who cooks, be that girl! Don't be a best dating sites jerk. Silence is always better than strange conversations just for the sake of talking,and don't force it because you will end up saying stupid and embarrassing which will end up ruining the moment. Explain a couple, or one, of valid reasons why you don't like sex. Mimic their voices, expressions, or movements. Don't say sorry if it wasn't your mistake! It can also cause to them to distrust your sincerity, which will dampen any chances they'll fancy you. It doesn't matter how many delightfully winning asides he has included in profile about his cute devotion to his 96-year-old grandmother. Remember, they are women who have baggage, but the potential benefits of having a woman and her kids in your life outweigh the drawbacks. Decide when to move to the next step in making eye contact. In particular, don't worry about the finer points of looks: as with a nice car you've had for a while, you won't notice the details over time but just fondly recognize them overall. Keep the information on your online dating profile light and simple -- and the same goes for the first date. Dating sites featuring millionaires looking for dates. Once they get used to that, eventually they will expect less from you and talk less to you. You should have no trouble getting that number. Act dumb. In addition, if she's certain you're able to poke fun at yourself, it'll be easier to poke fun at her sweet foibles when you're more familiar with another without her seeing this as an attack on her. But getting too attached too soon is often the worst thing that can happen to a budding connection. An online dating profile is basically who you are in the virtual world of online dating.

SeaDevil AUV

SeaDevil is Autonomous Underwater Vehicle (AUV) designed to perform various tasks using custom electronic circuits, array of sensors, on board computer and powerful battery cells. Highly hydrodinamic body of AUV is composed mainly of carbon kevlar composite with steel reinforced ribs which enables diveing to depths up to 150m while maintaining low mass and high maneuverability. AUV is powered by four high capacity (90Ah) LiFeYPO4 battery cells which can provide high current output to power AUV propulsion system while ensuring long autonomy. AUV is expected to meet the following requirements:

  • Speed of lateral movement of at least 0.5m/s
  • low mass of vehicle (35 kg)
  • working depth up to 150m
  • autonomy of 8 hours
  • dynamic positioning
  • high manoeuvrability (6 degrees of freedom)
  • high speed of data processing
  • modularity
  • simple maintaince

Such AUV demanded development of custom electronic modules which enables maneuvering of AUV, battery management and data acquisition from sensors. Crucial requirement in development of this system was modularity of whole system which is achieved by using standard modules. Each module has its own role in submarine system, and if necessary it can be easily replaced by other modules. Beside the need of developing hardware there is a need to develop a software for embedded systems and on board computer which will enable data analysis from sensors and control over the AUV. Hardware is composed of motherboard where several modules can be attached. Modules are separated by their function, so each module can perform specific task. For now there are four types of modules that can be attached to motherboard: Module for controlling electrical motors

  • >Controls two DC motors
  • Controls two digital servo motors
  • Measures current, voltage, power consumption and temperature
  • Performs autodiagnostics

Module for battery management

  • Charges LiFeYPo4 batteries
  • Implements battery management (cell balancing, over and under voltage protection)

Module for hydrophone monitoring

  • Location tracking using hydrophones and triangulation

Module for analog measurement

  • Precise measurement of analog signals (current, voltage, pressure)

Motherboard

  • Performs diagnostics of all attached modules
  • Communicates with on board computer and modules
  • Enables mechanical and electrical bonding of all modules with motherboard

Special care in designing printed circuit board (PCB) is devoted to heat dissipation and topology of conductor wires to avoid problems relating to overheating and electromagnetic interference which can lead to irregular operation of system. Motherboard contains circuitry to perform diagnostics on all modules which is able to disconnect power from faulty modules in order to preserve integrity of AUV. AUV propulsion system

  • Four azimuth thrusters for thrust vectoring
  • Two bow thrusters for pitch control
  • Four high torques DC motors (Speed 900) for azimuth trhuster
  • For RC servo motors (Futaba S3010) for azimuth thrusters
  • Two medium torque DC motors for bow thrusters

On board sensors

  • High precision pressure sensor
  • Several temperature sensors
  • Inertial Navigation System (INS)
  • Voltage sensors for each battery cell
  • Current sensors for each electrical motor and whole battery pack
  • Three hydrophones (TC4013)
  • Two industrial HD cameras (BlueFox)
