Prof Richard Ocaya from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) Qwaqwa  Campus has achieved a significant milestone with a newly patented invention. This patent, developed in collaboration with researchers from Turkey and Saudi Arabia, is the result of work that began in 2017, focusing on a special material known as graphitic carbon nitride.

This breakthrough in temperature measurement technology aligns perfectly with the university's Vision 130 commitment to innovation and addressing global challenges. The new device offers a unique solution to a longstanding issue in the field, providing accurate temperature measurements across an extremely wide range. Existing solutions often require multiple devices, leading to increased costs and reduced accuracy, but this invention simplifies the process.

The device, based on a combination of graphitic carbon nitride and silicon, can measure temperatures from -250°C to 250°C with exceptional consistency and linearity. This range and accuracy set it apart from current technologies, making it suitable for various applications, from standard temperature measurement to specialized settings involving extreme temperatures. It could be especially valuable in deep-space exploration, where equipment faces drastic temperature fluctuations.

The patent underscores the university's commitment to fostering collaborative research, a key aspect of Vision 130. Prof Ocaya attributes the success of the invention to the robust nature of the team, established in 2015. The team is now seeking to commercialize the technology by licensing it to a suitable partner, with organizations like NASA expected to show significant interest.

Prof Ocaya advises other academics considering patenting their inventions to ensure the patent solves a real problem uniquely and is based on sound principles. This makes the invention reproducible and protects it from being copied, assigning exclusive rights to the patent holder. Patenting allows for either manufacturing the devices or licensing them to third parties for royalties and profit. He notes that the main consideration is that the innovation must be practical and solve a specific problem in a novel and commercially viable way. He also acknowledges the challenge many academics face, as the "publish or perish" mentality often leads to choosing scientific articles over patents.

Despite securing the patent, Prof Ocaya and his team continue their research efforts, exploring new possibilities while balancing practical research with academic pursuits. He believes the invention will significantly impact the field of temperature measurement, being integrated into many new designs requiring such measurements.

The university proudly supports this innovative research and anticipates its real-world impact, furthering Vision 130's commitment to increasing UFS's research capacity and capability.

“Ninety percent of deaf children are born into hearing families. When parents first receive the news, they are shocked, angry and confused,” says Susan Lombaard, Acting head of the Department of South African Sign Language at the University of the Free State (UFS).

The department hosted a workshop, “Early intervention options for the child with a hearing loss”, on Friday 12 May 2017 on the Bloemfontein Campus. “It is the first time a sign language workshop of this kind was hosted by the Department of South African Sign Language at the UFS,” says Lombaard, who facilitated the workshop. They hope to make it an annual event.

Parents of deaf children do not always know how they will communicate with their children or where the child must attend school. The workshop aimed to provide parents with the necessary information on different communication options and also touched on school placement.

Support group for parents established
A support group for parents was also established, the first of its kind in the province. It will provide much-needed support, information and guidance for parents of deaf children.

Some of the speakers at the workshop included Anri Esterhuizen, an audiologist; Marianne Kühn from the Carel du Toit Centre, Marisa Vermeulen, who is a mother of two deaf children, and Phillip Cook, the headmaster at De la Bat School for the Deaf in Worcester, in the Western Cape. Jeannie Cook, also a presenter, provided information on sign language acquisition of the small deaf child, which is done through creative play.

Professionals have responsibility
South African Sign Language is a language in its own right and is not international. “Sign language is a visual language with its own grammar and syntax different from spoken language,” Lombaard said.

There has been much controversy surrounding teaching deaf children to speak and teaching them to sign. “We as professionals have the responsibility to provide information on all options. This is to help the parent make informed decisions about communication and school placement.”
