Claim 0:
1. A device comprising memory storing instructions; and
at least one processor that executes the instructions to perform operations comprising:
receiving a first signal representing a pulse wave relating to heart activity of a subject,
receiving a plurality of second signals representing time-varying information on a pulse wave of the subject;
identifying a first feature in the first signal;
identifying a second feature in one of the plurality of second signals; and
calculating a physiological parameter of the subject based on a difference between the first feature and the second feature;

wherein the device further comprises:
an acquisition module, wherein the acquisition module includes at least one acquisition unit, the acquisition module comprising:
an input device to receive information, and
a processor to further process the information;
an analysis module, the analysis module comprising:
a processor configured for performing operations, and
a plurality of operation units for collectively performing operations coordinated by a server;

wherein the analysis module is configured to calculate the physiological parameter of the subject based on the acquired information, and further comprises:
a pretreatment unit configured to pretreat the first signal and the second signal prior to calculating the physiological parameter, a pretreatment unit comprising:
at least one pre-treatment sub-unit to perform at least one pre-treatment steps for pre-treating the acquired signals in series and in parallel;

a recognition unit configured to analyze a feature of the acquired information, the recognition unit comprising:
at least one recognition sub-unit for processing at least one type of signal;

a calculation unit configured to perform a calculation based on the feature from the recognition unit, the calculation unit comprising:
at least one calculation sub-unit to perform calculations; and

a calibration unit, the calibration unit comprising:
a pneumatic device for acquiring at least one set of calibration data,
a controller for controlling a parameter of a process or an operation, and for processing and signals and information,
a storage for storing data, signals, information, calculation models, and calibration models, and
a transceiver for receiving or transmitting data, signals, information, or instructions.
