Natt med Annelie ?

Idag träffa jag en tjej från vetlanda som påstod att hon heter Annelie eller Pernilla, jag kolla av henne, och så hette hon förståss ej. Hon attackera mig med massa snack. men var eg inte så tuff. vad hon ville var inte klarlagt.

some word about receiver and wireless, with cmos mems loudspeaker


4. (Electronics) the equipment in a telephone, radio, or television that receives incoming electrical signals or modulated radio waves and converts them into the original audio or video signals

6. (Electronics) the equipment in a radar system, radio telescope, etc, that converts incoming radio signals into a useful form, usually displayed on the screen of a cathode-ray oscilloscope

Remember MEMS Sensor

sunlight - Iridium flare - convert to watt/m3 (work as a rectenna)
tranceiver - satellite modem
RFID - temperated battery - local heater
CMOS MEMS Sensor (ex vibrator) (CMOS MEMS Loudspeaker and CMOS MEMS Microphone)

Mems Sensor - vibration

Mems Sensor - Vibration

system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, lighttemperaturevibrationmagnetism, or chemicals. They are usually operated on acomputer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few millimeters and they may be vulnerable to electromagnetic disablement and destruction by microwave exposure.



From Wikipedia, the free encyclopedia
For mechanical oscillations in the machining context, see Machining vibrations.
For other uses, see Vibration (disambiguation).
Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.
Vibration is occasionally "desirable". For example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, or mobile phones or the cone of a loudspeaker is desirable vibration, necessary for the correct functioning of the various devices.
More often, vibration is undesirable, wasting energy and creating unwanted sound – noise. For example, the vibrational motions of engineselectric motors, or any mechanical device in operation are typically unwanted. Such vibrations can be caused by imbalances in the rotating parts, uneven friction, the meshing of gear teeth, etc. Careful designs usually minimize unwanted vibrations.
The study of sound and vibration are closely related. Sound, or "pressure waves", are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, when trying to reduce noise it is often a problem in trying to reduce vibration.
