Keys and consoles are used in various authentic connections, particularly human- machine interactions in the present state of art of Human Machine Interfaces (HMI). Automatic Teller Machines (ATMs), Charge/MasterCard machines, and pass-code-based support frameworks are a few cases wherein an individual has to touch the keys to provide a secret code are instructions to the machines. However, in situations such as the new COVID 19 pandemic, it is not desirable for customers to touch the same keys as it may cause easy spreading of chronic infections. There is therefore a need to provide a way to input data by users without physically touching any keys. This need is met in our design by offering a device and method to accomplish key or keyboard operation input operation based on the detection of a user finger with low power the laser light.

AbstractA workshop on problems related to the analysis of nicotine and nicotine metabolites in body fluids at levels pertinent to the human situation was held in November 1974 in Stockholm. It was organized by C. Enzell, B. Holmstedt and A. Pilotti at the request of the Medical Advisory Board of the Swedish Tobacco Company. The goal of the workshop was to summarize the present state of art in the area outlined by the organizers and to discuss critically the advantages and limitations of the different analytical methods available today. EIeven experts in the field of metabolism, detection and biosynthesis of nicotine and related compounds were therefore invited to present papers on these topics and to participate in the discussions. AIl speakers invited were able to attend and the papers were arranged in the following groups:Each speaker had one hour and a half at his disposal which included the discussion which, due to the informal atmosphere and the smaII number of participants, was very lively and fruitful. The papers read at this workshop comprise a very valuable coverage of recent research in the fields of metabolism of nicotine and minor tobacco alkaloids, and of the various methods available for detection of these alkaloids. The abstracts are given below, while full papers, now edited by A. Pilotti, can be obtained on request from C. Enzell of the Swedish Tobacco Company
