Components for a recording from a single flight mill include two 100-Ohm 1/2-Watt resistors, a coil of wire, 1 LED bulb, a photoresistor (light-dependent resistor), and a 1.5 V laser pointer (with a power source) (Fig.
The toothbrush switches and the photoresistor value data are read here.
This solution incorporated several sensors; we used a photoresistor to detect the status of the parking places.
One piece of evidence can be found in [1, 2], where we showed that the most likely situation is the opposite one, where [G.sub.S] accounts well for the gain of the photoresistor because the [G.sub.B] contribution is negligible.
Sumitomo established an advanced materials section that dealt in electronic materials, and tried to strengthen the photoresistor business for semiconductors in 1991.
This variable beam was then caught by a photoresistor (Vactec VT 732E 77 29, EG & G Vactec, 200 Orchard Ridge Drive, Suit 100, Gaithersburg, MD 20 878, USA) mounted within a plastic black cylinder (25 mm long).
One spectrometer was constructed from a film canister using an interchangeable LED as the combined light source and monochromator and a photoresistor as the detector.
The resonant circuit is loaded on a photoresistor, which is modulated at the frequency of the LF signal coming from the analyzer through an optic fiber.
In the second stage, the nanomask was patterned onto surface of the as-prepared diamond films by a nanolithography procedure with positive photoresistor. Au was then deposited onto the as-patterned diamond films at room temperature employing sputtering equipment [22].
