[19] 5. Heart Rate Algorithm 5.1 HR calculation per beat When calculating HR of each beat, 9 beats including previous 4 beats and following 4 beats are required. Number of effective sections / (( time of B9 – time of B1 ) / 60 ) Definition of “section” is the interval between consecutive beats such as B1 and B2, and in case 1 of the 2 beats is A ( Artifact ) , exclude it from effective section. If there are less than 5 effective sections, no calculation. As the above picture, if beats S A N N V N N N N are within a section of 5 seconds and the excluded section is 1 second, the V beat in the center will have HR value of 6 / ((5-1) / 60) = 91 bpm. 5.2 Average HR calculation of a section Average HR of a section is calculated with the beats included in the section. If the above data is within a 20 second frame, the average HR is calculated as follows: Number of effective sections / (( Total length of effective sections ) / 60 ) At this time, “section” refers to the interval between consecutive beats such as B1 and B2, and in case 1 of the 2 consecutive beats is A ( Artifact ) , exclude it from effective section before calculation. Therefore, there are 12 effective sections, and if the total length of invalid sections is 2 seconds , the average is calculated as follows: 12 / ((20-2) / 60) = 40 bpm

Recommended separation distance where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as deter-mined by an electromagnetic site survey, a should be less than the compliance level in each frequency range. b Interference may occur in the vicinity of equipment marked with the following symbol :

Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to verify normal operation.
