Brannock Device Brannock Device The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person's shoe size. The son of a shoe industry entrepreneur, Brannock attended Syracuse University, New York. Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, patenting his first prototype in 1925 and an improved version in 1927. The device has both left and right heel cups and is rotated through 180 degrees to measure the second foot. Brannock
ISO 7637 environments, including a load dump simulation. ISO 7637 is referenced by many vehicle manufacturer standards and individual waveforms are modified to meet specific requirements. ISO 7636 includes both immunity and emissions components of electromagnetic compatibility testing. This standard, including ISO 7637-2 places specific requirements on test equipment that can be used to replicate electrical occurrences. ISO 7637 ISO 7637 Road vehicles -- Electrical disturbances from conduction and coupling is an international electromagnetic compatibility vehicle standard published by the International Organization for Standardization (ISO), that relates to 12 and 14 volt electrical systems. As of November 2018, four parts of ISO
