Manual Reaction Time Device Using Extraction and Disposable Timing

The patent extracts the essential measurement function from complex computer-based systems and implements it using simple manual timing mechanisms. The reaction time measurement is achieved through basic stopwatches or timer devices combined with manual signal delivery, eliminating the need for computers, specialized software, and complex electronic infrastructure while maintaining adequate measurement precision for clinical purposes.

The invention replaces expensive, complex computer-based measurement systems with inexpensive, simple timing devices such as stopwatches or handheld timers. These basic timing instruments can be easily obtained and discarded or replaced, eliminating the need for costly computer hardware and software licenses while providing sufficient measurement capability for assessing reaction time in concussion evaluations.

The patent employs inexpensive timing devices such as stopwatches, handheld timers, or even simple digital watches that can be purchased for minimal cost. These basic timing instruments replace expensive computer-based measurement systems, reducing the cost per evaluation from hundreds to dollars while maintaining adequate measurement precision for clinical concussion assessments.

The invention extracts and eliminates the costly components of computer-based systems including computer hardware, specialized software licenses, and electronic infrastructure. By removing these expensive elements and retaining only the essential timing function through simple mechanical or basic electronic devices, the system achieves significant cost reduction while preserving measurement capability.

The patent incorporates feedback mechanisms where the examiner provides immediate verbal or visual confirmation of stimulus delivery and response timing. The timing device displays measured reaction times to the examiner who can then verify the measurement process, correct any timing errors, and ensure accurate recording. This feedback loop compensates for the limitations of manual timing methods and maintains measurement reliability.

The invention implements preliminary actions including pre-positioning timing devices, pre-establishing stimulus delivery protocols, and pre-instructing the examinee on response requirements. The examiner prepares all measurement equipment and procedural details in advance, ensuring that when the measurement occurs, everything is ready for accurate timing. This preparation minimizes delays and ensures consistent, reliable measurements despite using simple manual methods.
