By integrating modular design, innovative propulsion systems, and advanced autonomous capabilities, Howard’s drones promise to transform various industries. The potential for quieter, more efficient, and powerful drones opens new possibilities for their application, paving the way for a future where intelligent machines play an increasingly vital role in our daily lives and industrial processes.

The ILT 800 series are a family of UV Curelight (or “belt”) radiometers that measure the process irradiance from fluorescent lamps used for sterilisation, high intensity mercury or xenon lamps used for curing, and LEDs used for photolithography. It is important to ensure that the irradiance or UV dose delivered to a surface or object satisfies threshold activation and uniformity criteria, for the process to be effective. With the ILT 800, you can easily check if your lamp’s energy levels of are high enough, or whether your system is in need of maintenance.

From the measured spectral power, the desired radiometric, photometric or colorimetric metrics can be calculated. A spectroradiometer avoids the potentially significant errors that filtered photometers and colorimeters suffer from where the spectral response of the filtered sensor doesn’t exactly match that of the target observer, for example the photopic response of the eye. This is an important consideration; a high-quality photometer may have a average spectral mismatch (the f1’ factor) to the photopic observer of 5% over the 380-780nm visible light band, but can still yield errors of 50% or more when used to measure blue or red LEDs, for example.

A radiometer can also be equipped with a filter that limits or adapts the spectral response and these are typically used in safety or medical applications where certain wavelengths are more dangerous or more efficacious than others. Examples of this are measuring the safety of UVC light sources, measuring the erythemal effectiveness of a UVB source and measuring blue phototherapy lights used for the treatment of bilirubin (jaundice in newborns).

The ILT800 simplifies measurement by continuously sampling until UV light is detected, then automatically initiating a measurement. The device’s large OLED display provides both numerical and graphical representations of the irradiance and dose. Sampling occurs at 3000 readings per second, allowing belt (process) speeds of up to 77 meters per second, providing a high-resolution profile for both continuous and pulsed light sources.

With the ILT 800, you can easily check if your lamp’s energy levels of are high enough, or whether your system is in need of maintenance.

It is important to control not only the dose of the UV light that your products receive, but also the irradiance level, to ensure proper curing throughout the entire coating or layer. In order to verify that the proper irradiance is maintained along the entire exposure path, a profiling radiometer is required. The ILT800 is a self-contained, powerful yet easy-to-use meter that captures, displays and stores all your data, across all your UV/VIS processes.

If Howard’s tangential flight concept using magnetic propulsion is realised, it could revolutionise drone technology. This system may offer quieter, more efficient, and powerful alternatives to traditional propeller-based drones, expanding their usability in sensitive environments.

The ILT800’s rapid measurement speed provides a high-resolution profile of your system.  System abnormalities and process failures can be pinpointed easily, and proper maintenance and adjustments can be made quickly, allowing you to get up and running faster.

The Lynchpin drone’s ability to perform complex manoeuvres and maintain stability while doing so demonstrates significant advancements in AI algorithms for real-time decision-making and control. This enhances the precision and reliability of autonomous operations.

Whereas radiometers, photometers and colorimeters employ photodiodes with special filters, a spectroradiometer measures what is called the spectral power of the light source, which is the amount of light at each wavelength. The spectral response of the spectroradiometer is calibrated at each wavelength, which therefore avoids the error that arises from measuring the irradiance of broadband light sources with unfiltered radiometers (or even radiometers equipped with normalising filters).

Tangential flight, a concept developed by Howard, involves a novel propulsion system that deviates from conventional methods. This system aims to use magnetic forces or other innovative means to achieve flight, potentially leading to quieter, more efficient drones. The principle behind tangential flight is to “decouple” traditional propulsion mechanisms, resulting in drones that can move smoothly and efficiently through the air.

Acclaimed Hollywood actor Terrence Howard, has ventured into the world of advanced drone technology with his invention of the Lynchpin drone and the concept of tangential flight. These innovations promise to revolutionise the way drones operate, presenting new possibilities for both commercial and industrial applications.

A colorimeter is a type of photometer that combines three of four photodiodes each with a filter that closely matches the tristimulus response of the eye (the XYZ or XRXBYZ tristimulus colour matching functions). A colorimeter measures the emitted colour of the light source under test, and reports this as tristimulus values, as CIE chromaticity coordinates and as correlated colour temperature (CCT) values or as a dominant wavelength. The Y filter of a colorimeter is the same as the photopic filter in a photometer, hence a “tristimulus” colorimeter can also function as a photometer.

The ILT800 comes with an extensive software suite including the CureRight internal meter software, CureRight PC software for programming and data extraction, and ILT’s Datalight III with full API for custom programming. The CureRight PC software allows customers to download all saved readings to a PC. It also enables programming of the ILT800 with up to 20 device IDs (light source model or nickname), programme the date and time, minimum light level, allowable delay between readings, auto shut off time and more. The meter’s internal software facilitates measuring, storing, viewing and comparing over 1000 saved measurements including profile, date/time, temperature, irradiance, and dose.

Radiometers and photometers consist of a photodetector, an electrical readout and a calibration. The spectral response of a photodiode varies with the wavelength of the incident radiation. This means that 1 W/m2 of irradiance at 350nm in the UV will produce a different electrical current compared to 1 W/m2 of red light at 650nm.

One practical application of the Lynchpin drone is in construction and heavy lifting. For example, on a construction site, these drones can autonomously lift and transport heavy materials such as steel beams or concrete slabs. By linking together to form a larger unit, the drones can handle tasks typically performed by cranes, improving efficiency and safety.

The modular design, where multiple drones can combine to form larger units, introduces a new dimension to collaborative robotics. This scalable approach allows drones to adapt to various tasks, improving flexibility and efficiency in operations.

The photodetector would typically be fitted with an optical filter which modifies the inherent spectral response of the sensor. For a radiometer to measure the amount of monochromatic light, you only need to know the calibrated spectral response of the photodiode at the relevant wavelengths. If the light source is anything other than monochromatic (which is the case for all light sources except lasers), a radiometer with bare photodiode cannot yield absolute radiometric measurements. A “radiometric” filter can be fitted to the photodiode that normalises the response over a limited wavelength range, typically ±10% from 450-950nm, which provides a partial solution.

The Lynchpin drone is a modular, omnidirectional drone system that leverages a unique geometric design to achieve unprecedented flight capabilities. This drone features twelve propellers and twelve opposing vortices, allowing it to move in ways traditional drones cannot. The design enables it to perform complex manoeuvres, maintain stability, and combine with other drones to form larger, more powerful units.

A photometer is similar to a radiometer, but the photodiode is equipped with a special filter that modifies the spectral sensitivity of the detector/filter combination so as to match as closely as possible that of the human vision system, defined at the CIE spectral luminous efficiency for photopic vision (“photopic” response). The photopic response of the human eye strongly favours green coloured light, with blue and red light being perceived as less intense. Thus, a photopic sensor ranks the brightness of light sources in close agreement to how the human vision system would perceive them.

The ILT 800 is a radiometer. Other types of light meter are photometers, colorimeters, spectrometers and spectroradiometers, which all measure the amount of light but they operate in fundamentally different ways and have advantages and disadvantages.

The ILT800 spectral filtration was designed to match the photoninitators’ response to UV light which is directly related to its absorption and is very wavelength selective. Most lamps emit broadband UV/IVS/IR, and the lamp’s output may not change evenly over all wavelengths. The ILT800 filters were designed to monitor changes in lamp output in the parts of the spectrum that effect the absorption, and in turn the effectiveness of the curing.

The five radiometers in the ILT 800 family all measure UV irradiance (W/cm2) and dose (J/cm2), the key difference between them being the exact spectral band in which the measurements are taken.

A spectroradiometer is the name given to a spectrometer that is equipped with appropriate collection optics and an absolute calibration. A spectrometer is an optical instrument that employs a diffraction grating that physically separates the incident light into its component wavelengths. Each discrete wavelength is imaged onto an array photodetector, which allows for the recording of a spectral power distribution instantaneously.
