The sensors include dry EEG electrodes, accelerometer and pulse oximeter. Examples of peripheral devices are&colon; blood pressure cuff, pulse oximeter, and glucometer. The pulse oximeter fits over a fingertip or an earlobe. Biofeedback can be delivered using a pulse oximeter. Supplemental oxygen, cardiac monitoring, and a pulse oximeter should be applied to the patient. The pulse oximeter may be incorporated into a multiparameter patient monitor. Pulse CO-oximeters estimate carboxyhemoglobin with a non-invasive finger clip similar to a pulse oximeter. People's oxygen levels are to be monitored with a pulse oximeter. Under BOC management, the pulse oximeter market expanded significantly. At E3 2010, Ubisoft introduced their own pulse oximeter sensor, "Innergy". Biox introduced the first pulse oximeter to commercial distribution in 1980. The original oximeter was made by Glenn Allan Millikan in the 1940s. Wilber invented the company's technology and developed the first oximeter patent.
