Abstract: The present invention proposes a relaxation state evaluation system and method and a computer program product thereof. The method comprises steps: measuring ECG data of a user; analyzing the ECG data to generate a first, second, third and fourth parameters, wherein the first parameter is the short-scale entropy slope of the user before cardiovascular disease treatment (CVDT); the second parameter is the difference of the post-CVDT and pre-CVDT mean RR intervals; the third parameter is the logarithm of the variance of the pre-CVDT high frequency NN intervals; the fourth parameter is the logarithm of the ratio of the variances of the pre-CVDT low frequency and high frequency NN intervals; working out an evaluation index, which is a function of the abovementioned parameters; and evaluating the relaxation state of the user, wherein the user is determined to be in a relaxation state if the evaluation index is over a threshold.

Abstract: A cable drag chain includes a number of first coupling members, a number of second coupling members engaging with the first coupling members, a number of latching members each including at least one mounting portion, a first fixing member and a second fixing member engaged with opposite ends of the first and second coupling members, and a sliding member slidably coupled to the first fixing member and including a latching portion. When the sliding member slides from the first fixing member to the second fixing member, the latching portion urges against the at least one mounting portion of each latching member to engage each latching member with corresponding first and second coupling members for holding a cable.
