JKI provides complete and modular solutions to
tough measurement and control application challenges. We employ both
off-the-shelf and custom techniques to find and satisfy the most demanding
of specifications. Major aspects of instrumentation are presented
Featured Custom Examples:

Sensors and Measurement.
any off-the-shelf sensor module can be integrated into a measurement system.
In these case where a measurement is needed, JKI has often developed custom
solutions and sensors for specific cases. Common sensors used in
our systems include:
We may also be able to tap into existing data
lines, and extract or insert signals.
Often sensory level signals are very small, non-linear,
noisy, and have poor characteristics. JKI commonly implements gain,
filter, offset, linear mapping, F/V conversion, and other signal processing
stages to extract the best information possible given the signal present.
In many cases, local pre-amplifier stages reduce excitation noise.
Several common stages will soon be available individually in our CyMods
(Circuitry Modules) line, described at the end of this section.
stand-alone applications, JKI has build many types of custom enclosures,
potted modules, or just cores (tested circuitry to be installed in clients
products). Our custom instrumentation devices are designed and built
to your specifications and performance standards. Devices can be
the remote extensions of local data collection hubs, or stand alone units.
Waterproof sealed units can be operated via magnetic pulse and the use
of docking stations.
implements optical, magnetic, and many choices of RF telemetry. We
use standard, coded, noise reducing, and other protocols depending on your
application. JKI also developed its own error avoiding coded non-standard
syntax which helps verify data readings. Optical and magnetic methods
are good for short range applications, where we use RF methods in several
bands that go from 30ft to 10+miles. Higher power units will draw
Embedded data logging and threshold revues are
often used to measure store data in remote, traveling, or non-networked
applications. Nonvolatile memory and data buffering can be time stamped,
and can also be review according to thresholds to trigger alarms.
Apply our years of R+D in energy efficient units, some of our embedded
units are still working after 3 years. Data logging can also be accompanied
by periodic downloading to permanent storage. Magnetic, optical,
or push-button triggers allow memory to be periodically cleared out. Auto-ID
and RFID techniques often allow triggering and downloading of proximal
data to be automatic.
once signals are digitized at the source, they are directly sent to a computer
for storage and graphing. In other cases, signals coming from transmitter
(sensory) modules are either digitized or similarly modulated for communications
purposes and it is desirable to convert the signal back into analog voltages/currents.
Sensory Re-Creation produces analog signals which are often brought into
a clients existing DAS system. Analog signals re-created at the receiver
may be zeroed, scaled, mapped, displayed on local panels, applied to thresholds
or alarms, and many other applications without involving the computer.

are output as line audio which was read directly by a PC sound card and
uploaded to the internet for review.
many cases, sensory inputs are just the beginning of more complex process.
Calibrated signals can be used to present highlights to operators.
Via analog and/or digital means, 'virtual operator' stations insure your
process runs smoothly. Especially in the case where stations are
remote and utilizing a dedicated computer is impractile. Our process
control stations can also be redundant local nodes of computer controlled
Large Scale Array Controller.
In the case where you need synchronous control
and remote pattern generation of a large number of outputs, JKI introduces
the Large Scale Array Controller. The same protocol and driver architecture
utilized by JKI's ElectroTactor and VibroTactile Stimulation systems is
applied here to .
Each synchronous pattern generator core handles
128 channels per channel band. LSACs are available in 1 to 128 channel
bands, or a maximum total of 16384 channels. Communications and control
can be direct connect, RS/RF232, or other methods. The syntax is
TSComm. TSCom can be generated by our Manual Control Consoles, Embedded
Control Consoles, or implemented by computer interface.
Achieve synchronous control of high numbers of
lights, rockets, pyrotechnics, vibration units, motors, devices, etc.
Output patterns can be controlled by our host or by the embedded patterns
within the driver enclosure. Create dynamic pulse trains, coordinated effects,
timed routines, and more.

Coming soon from JKI are these discrete instrumentation
building blocks. CyMods (circuitry Modules) are stand alone signal
process, data acquisition, communications, and similar instrumentation
based products. How often have you spend a fortune on new DAS equipment
just to boost a signal, apply a bit of filtering, offset, zeroing, data
communication modulation/demodulation, etc. JKI offers a handy and
simple method what can be allied to new and old equipment.
Need discrete digital waveform generation, digital
function generation, sequenced pulse trains, etc?? CyMods are coming
soon. CyMods.com, by JKI
