Abstract: The invention belongs to the field of electronic instruments for measuring physiological parameters and medical diagnosis. The patellar reflex is a fundamental part of neurological examination when analysing damage to peripheral neurological structures with central medullary integration. At present, this reflex is visually assessed by the practitioner. In addition, it would be of interest to the practitioner to obtain information relating to latency and whether the reflex is polykinetic, parameters which are difficult to assess visually. The instruments of the current state of the art are disruptive to the patient, are complicated to position and/or they provide unprocessed information. The invention enables the reflex to be objectively measured, is minimally disruptive to the patient and calculates the relevant parameters immediately and automatically. It incorporates sensors, electronics, numerical signal processing for the extraction of parameters and elements for delivering the information.

Abstract: The Lap Shade provides fun and essential device for business people and students. The Lap Shade will expand your limitations where you can operate and enjoy your portable lap top computers, notebook computers, portable DVD players and such like portable computers and players outdoors, and view your screens clearly where the sun shines instead of being confined to the indoors because of the sun shinning on the screens. It's easy to attach to the computers or players and easy to fold and it's compact. The Lap Shade is also used to give you privacy as you work on your desk top computers or portable computers and portable DVDs from those that stand or sit next to you trying to view your screens as you work inside, outside, coffee shops and other locations. The Lap Shade can become a testing booth for desk tops or portable computers for companies and schools.
