Active and Passive Light Sensor - light detection system

APLS has various applications-

In Mode 1 - A Passive light detector able to indicate relative intensity of ambient light whilst walking/moving from a directed external light source i.e. daylight, torchlight , mains light or laser pointer.

In Mode 2 - Built-in LED light emitters of switchable Ultraviolet and/or Infrared light, are pulsed at a resonance frequency of the selected LED light frequency.
The APLS is able to indicate the presence of an object within the range of emitted light and the detector/sensor capable of reflecting light.
Responses are indicated on a 10 led display as audio from a coupled sound generator
If a reaction is indicated on the LED display, a corresponding tone will be heard as an increasing audio tone.

The switched LED Infrared emitters are ideally suited for use in darkness, the switched Ultraviolet are ideally for use as partial illumination.
A most successful use of this technology was captured by television.

DIGITAL LIGHTING click for details
An active system

An alternative lighting system for use with still cameras, video cameras and our eyes.
DL is a 'pulsed' lighting system - a high frequency, pulsed/strobbed light can freeze motion similar to a dance floor strobe flashing light.
DL uses LED illumination to allow a new experimental photography technique.
3 individually selectable LED colours - infrared, blue and ultraviolet (recommended) are fitted (others available on request)
Switched and in 2 frequency ranges, an auto resetting ramped pulsed drive scans through a wide range of frequencies every 2 seconds (aprox)
The DL is also capable of manual pulsed frequency control.
When used with still cameras a tripod and long exposure time (2-4 seconds or longer) is recommended .
It can be used with standard cameras on a 'night scene' setting and secured on a firm base
(results will vary with various cameras and may not function correctly with all recording systems)

SENTINEL click for details
A passive system

The Sentinel is an energy change detector and is complementary to the PX 09/10 or an alternative to an EMF meter.

The Sentinel can be used as an electronic trigger object reacting to changing electric fields or magnetic fields, or with optional extra - vibration sensor.
A 9 LED centered display able to indicate positive or negative energy change from a verity of energy - electric field, magnetic field and vibration.
Tone generator linked the LED display for an audio response
Selectable - built in electric field or magnetic field sensors
Able to detect minute changes in electric or magnetic fields
Several sensitivity adjustable controls
Sockets for external sensors.
Can be used in combination with a portable battery powered plasma ball (not supplied)
Plased in closed proximity as an EMF change detector.
A multi-purpose instrument

At the judgment of the operator the signal from an external microphone can be mixed with the white noise.

Can be used with or without the microphone

Features-
Electronic mixing of white noise. and audio
Electro-magnetic mixing of white noise and audio
Microphone mixing level
Volume control
External microphone socket
Line out/record socket

PX 10
With the features of the PX 09 with the following additions
It contains an active EMF generator with adjustable output level
Microphone input with adjustable mixing level.
Adjustable EMF input sensitivity

The active EMF emitter forms an energy bubble that if affected by an external force or object will be indicated as a change on the LED display and affect the audio tone output.
It includes a speaker and audio amplifier.

Features
10 Led display
Tone generator with volume control
EMF sensitivity level control
Microphone input level control
EMF generator output level control
Audio volume control
