During September 2017, Stark Ltd paid $319,000 in salaries of company engineers and consultants to conduct tests on motion-sensing systems currently available in the market, with a view to making possible modifications and obtaining the knowledge.
During November 2017, A new motion-sensing system was designed and a basic model produced at a cost of $215,000. This model was determined to be unsatisfactory as the materials of which it was made were not suitable.
During January 2018, a further $101,000 was incurred in costs for the new motion-sensing system. Stark Ltd purchased a software for the motion-sensing system at a cost of $93,000.
During April 2018, Stark Ltd spent a further $230,000 to incorporate the new material into the design of the new motion-sensing system. By 30 April 2018, Stark Ltd was convinced it now had a viable product, because preliminary tests showed that the new motion-sensing system was far superior to any other available on the market.
During May 2018, Stark Ltd developed a prototype of the motion-sensing system and proceeded to test it with a variety of models of audio visual systems for which they provided components. By the end of May, the motion-sensing system proved to work successfully with the majority of the audio-visual systems available on the market and for which Stark Ltd supplied components. Further costs of $112,000 were incurred in this process. Additional costs of $38,000 were incurred for the workshops to train their manufacturing engineers with the newly developed motion-sensing system.
During June 2018, after receiving positive feedback from their manufacturing engineers of audio visual systems, Stark Ltd decided in June that they had a successful model and commenced planning production of the motion-sensing systems. Expenditures in June included $40,000 to display and demonstrate the new model to prospective purchasers.
