Photos of the Brazilian actigraph ACT10 produced by the company CE Brasil, also called “Tempatilumi” by researchers. The actigraph details can be found on the company's website (defunct) through the following link: https://web.archive.org/web/20071218222809/http://www.cebrasil.com.br/CE/Biomedicos.htm. "The ACT10 Actimeter is an electronic device that is attached to a person's body, like a wristwatch, capable of recording body temperature, movement intensity, ambient lighting and time of events, in order to assist in the acquisition of data on biomedical experiments. All of this information is stored in a non-volatile FLASH-type memory, together with time from a real-time clock. The system also has a programmable alarm according to the research needs."
