Analysis system and method for analysing the movement of a portion of the body and/or of a human prosthesis

Abstract

An analysis method (200) for analysing the pressure exerted by a portion of the body and/or of a human prosthesis comprises the following steps: sampling data generated by the portion of the body and/or the human prosthesis during a threshold calibration period (TCP) at a sampling frequency (Fs) in at least one condition of use so as to obtain an array of sampled data (d(i,j,t)) of at least one sensing unit (15ij); providing at least one threshold value (TA1, TC1) of the sampled data (d(i,j,t)) for the at least one condition of use and storing the least one threshold value (TA1, TC1) in a memory unit (24); comparing at the sampling frequency (Fs) the sampled data (d(i,j,t)) with the at least one threshold value (TA1, TC1) to obtain calibrated data (dc(i,j,t)), and storing the calibrated data dc(i,j,t) in the memory unit (24) and/or send the calibrated data dc(i,j,t) to a computing device (4) if the calibrated data dc(i,j,t) is greater than the at least one threshold value (TA1, TC1). A sensing device (1) for sensing the pressure exerted by a portion of the body and/or the human prosthesis, comprises a body (11) formed by a flexible material and having a plurality of superimposed layers (12), each layer of the plurality of layers being provided with a plurality of sensing units (10) arranged into the body (11) and configured for sensing the pressure applied by the portion of the body of the user and/or the human prosthesis, each sensing units (15ij) of the plurality of sensing units (10) being a capacitive or resistive/capacitive force/pressure sensing unit.

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population. Sampling has lower costs and faster data collection compared to recording data from the entire population, and thus, it can provide insights in cases where it is infeasible to measure an entire population.
Sampling (signal processing)
In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values. A sampler is a subsystem or operation that extracts samples from a continuous signal. A theoretical ideal sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired points.
Memory management unit
A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory. In modern systems, programs generally have addresses that access the theoretical maximum memory of the computer architecture, 32 or 64 bits. The MMU maps the addresses from each program into separate areas in physical memory, which is generally much smaller than the theoretical maximum.
