Detailed description of the embodiments:
[0006] Figure 1 illustrates a control unit for generating multiple signals according to one embodiment of the present invention. The control unit 10 receives at least one input from a user via a user interface 14 and transmits the at least one input to a first module 16 to generate a function layer 18 corresponding to the at least one input. The control unit 10 generates the multiple signals 12 from corresponding the function layer 18 and an intelligence module 20.
[0007] Further the components of the control unit and the function of the components of the control unit is explained further. The control unit 10 according to the present invention is chosen from a group of control units comprising a microprocessor, a microcontroller, a digital circuit, an integrated chip and the like. The control unit 10 comprises the user interface 12 through which the user can provide the inputs to the control unit 10 for generating the signals 12.
[0008] The inputs are chosen from anyone of the following comprising number of signals to be generated and the multiple ranges of characteristics of the signals 12. For instance, the multiple range of characteristics of the signals 12 are amplitude, pulse width and the like. For example, the user provides two inputs comprising two ranges of characteristics of PPG signals 12 (Amplitude and pulse width) and also a number representing the number of PPG signals 12 that are to be generated.
[0009] The range of characteristics of the signals 12 are not limited to above disclosed characteristics, but can be any other characteristics that are known to a person skilled in the art. The control unit 10 comprises multiple modules (14,16,20,22) for generating the signals. According to one embodiment of the invention, the control unit 10 comprises a user interface 12, a first module 16, an intelligence module 20 and a representative data module 22. The first module 16 is referred as a data transmission module. The data transmission module 16 receives the inputs that are provided from the user via the user interface 12 and generates corresponding functional layer 18 to each of the input provided.
[0010] According to one embodiment of the invention, the functional layers 18 are the mathematical form that are used to generate the signals 12. Each of the input has a corresponding functional layer 18 generated.
[0011] The control unit 10 further comprises a representative data module 22 having multiple data points related to the signals. In the absence of the data transmission module 16, the input from the user is directly provided to the intelligence module 20 for generating the signals 12.
[0012] Figure 2 illustrates a flow chart of a method for generating multiple signals according to the present invention. A method for generating multiple signals 12 according to the present invention. The method comprises following steps. In step S1, at least one input from a user is received via a user interface 14. In step S2, the at least one input is transmitted to a first module 16 for generating a function layer 18 corresponding to the at least one input. In step S3, the multiple signals 12 are generated from corresponding function layer 18 and an intelligence module 20. In step S4, the intelligence module 20 is trained by a representative data module 22 comprising multiple data points in the absence of the data transmission module 16.
[0013] The method is explained in detail. The user provides at least one input to the control unit 10 using the user interface 14. As mentioned above, the input will be a range of characteristics of the signal 12 and number of signals 12 to be generated. For better understanding of the invention, the inputs will be amplitude and the pulse width and the number of signals 12 to be generated will be twenty.
[0014] The amplitude and the pulse width values are provided to the data transmission module 22 for further processing. The data transmission module 22 upon providing the inputs generates the function layers corresponding to each input. For two inputs, the data transmission module 22 generates two function layers 18. The function layers 18 along with the inputs and the number of signals that needs to be generated are transmitted to the intelligence module. In the intelligence module 20, using any of the intelligence networks as known in the state of the art such as an artificial intelligence network, a deep learning technique, a machine learning technique and the like. The intelligence module 20 along with the function layers 18, generates the required number of signals 12 with the provided range of characteristics.
[0015] In this example, let the inputs are A1, P2 and the range of each of the characteristics will range from one to a maximum number. In this example, the range will be from one to five. Each input will be A11, A12, A13, A14, A15 and P21, P22, P23, P24, P25. The control unit 10 generates twenty signals as required by the user using the above-mentioned multiple amplitude values and the pulse width values. I.e., one signal will have A11 and P21 values and a second signal will have A11 and P12. Like this, the twenty signals generated will have all the combinations of amplitudes and pulse width values provided by the user.
[0016] In the absence of the function layer 18 in the data transmission module 16, the representative module 22 trains the intelligence module 20 using multiple data points that are preloaded. The inputs are provided directly to the intelligence module 20 and by taking into consideration the datapoints that are preloaded in the representative module 22, the control unit 10 generates the signals required by the user. According to one embodiment of the invention, the signal 12 is a photoplethysmogram (PPG) signal.
