Researchers at Rensselaer Polytechnic Institute have developed a technology which could improve VLSI testing by allowing for non-destructive testing of VLSI circuits under bias for electronic systems. With this new technology, researchers have focused on improving testing output as chip density increases along with decreasing chip sizes. Terahertz radiation (and related radiation at other frequencies – RF, sub-THz) is used to illuminate the chip under the test.
The terahertz (THz) band shows promise in terms of providing improved communications capabilities, including the ability for power-enhanced beam-forming and spatial multiplexing and reconfigurable array architectures that meet the capacity demands for 5G applications. All of these attributes of line of sight (LoS) systems in the THz spectral regime allow for wireless bit rates to be augmented without typical issues such as latency or noise complicating the picture.
Pictures taken with most camera flashlights are often considered unnatural looking due to a mismatch of the illuminance and color temperature between the flash light and the ambient light in the scene. Subsequently, image rendering software is used to enhance the picture to a desirable look or several pictures must be taken attempting a better capture. A smart light system has been developed, incorporating LED sources and a sensor, that studies the lighting environment and decides optimal light for specific applications.
This technology relates to highly sensitive and large area optical sensor arrays with smart control that feature wireless operation. The optical sensors convert sensed illumination into a corresponding impedance (e.g., capacitance, inductance, etc.). The resulting impedance can then be easily integrated into a wireless signal generator (e.g., an LC or tank circuit), such that a characteristic of the illumination (e.g., intensity, wavelength, etc.) can be translated into a wireless output.
Laboratory courses are a vital part of engineering and scientific education and training, but so far, lab courses have been considered impractical for remote education. Lab courses are traditionally conducted at a central location, with student, instructor, and experiment in close proximity to each other. As versatility of communications over the Internet increases, it is desirable to have a method to remotely conduct a lab experiment that allows a student to easily access the experiment from a remote location.
