The "work-made-for-hire" doctrine generally defines the relationship between a software developer and his or her client.

A segment of software code is a "work-made-for-hire" if it is either:

a) A work prepared by an employee in the scope of his or her employment; or

b) a work specially ordered or commissioned for use as [1] a contribution to a collective work, [2] as a part of a motion picture or [3] other audiovisual work, [4] as a translation, [5] as a supplementary work, [6] as a compilation, [7] as an instructional text, [8] as a test, [9] as answer material for a test, or [10] as an atlas, if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire. (17 U.S.C. § 101)

In either situation, the author of the code does not own the copyright in the code, as would be expected under the basic copyright framework. Rather, the person or business that employs the author or that commissioned the software owns the copyright in the code.
When a developer creates software as an employee, determining ownership of that software under the "work-made-for-hire" rule is relatively straightforward. Any work a developer creates within the scope of his or her employment is owned by the employer. Analysis of whether work is "within the scope of employment" can be extremely complex. However, at its most basic, if a developer writes a particular piece of software for work, his or her employer owns the copyright to that software.

“光电容积脉搏波描电法(PPG)正是借助光电手段在活体组织中检测血液容积变化的一种无创检测方法，它基于动脉血液对光的吸收量随动脉搏动而变化的原理。”

“脉搏波分析中的一些难点；脉搏波中存在多种干扰、噪声和伪迹，使得信号特征难以提取；脉搏波信号的特征参数(如周期、峰．谷值等)具有模糊性，每个特征参数都是在一定范围内变化着的量；同一个特征参数的正常值与异常值的区分阈值对不同的
个体都有所不同，这样造成参数确定、提取和识别的困难；脉搏波形态多变，在个体间、个体内都有一定差异性。要对其正确识别，又要使得运算量不至于过大是件困难的事。”
