Computerized method for adherence to physical restriction in the construction of an ITE hearing aid
View Patent ↗In a computerized method for adherence to physical restrictions in the construction of an ITE hearing aid, each component to be placed in the shell of the hearing aid has a collision plot associated therewith. The collision plot is generated as a scatter plot by measurement and simulation, and represents the physical extent of the influence of a particular property of the component on other components. When virtual representations of the respective components are moved relative to another in the e-detailing software for determining the physical positions of the components in the ITE hearing aid, the collision plot for a given component is visually displayed, so that it can easily be seen when another component invades that collision plot, thereby representing an unacceptably close relative position of the two components.
1. In a method for constructing an ITE hearing aid using an e-detailing program in which each component of the ITE hearing aid has a visually displayable virtual representation representing a physical size of that component, the improvement comprising the steps of:
for each of said components, electronically determining a collision plot that is larger than the virtual representation of that component and that represents a region within which that component exerts a non-mechanical influence on other components;
electronically logically linking the collision plot for a component to the virtual representation of that component;
at a display, visually displaying the collision plot for a first of said components together with the visual representation for the first of said components;
at said display, moving the visual representation of a second of said components with respect to the visual representation of the first of said components to identify an acceptable position of said second of said components relative to said first of said components in the ITE hearing aid; and
providing a visual indication at said display of an unacceptable relative position if said virtual representation of said second of said components invades said collision plot of said first of said components.
2. A method as claimed in claim 1 comprising generating said collision plots as scatter plots by measurement and simulation.
3. A method as claimed in claim 1 comprising, for each of said components, generating a plurality of collision plots respectively for different non-mechanical physical characteristics.
4. A method as claimed in claim 1 comprising generating said collision plot to represent a magnetic influence exerted by the component to which the collision plot is logically linked.
5. A method as claimed in claim 1 comprising generating said collision plot to represent an electrical influence exerted by the component to which the collision plot is logically linked.
6. A method as claimed in claim 1 comprising generating said collision plot to represent an acoustic influence exerted by the component to which the collision plot is logically linked.
7. A method as claimed in claim 1 comprising changing a size and shape of said collision plot of said first of said components dependent on an angle of the virtual representation of said second of said components.
8. A computer-readable medium encoded with program code for use in a computer with a computerized e-detailing program in which each component of the ITE hearing aid has a visually displayable virtual representation representing a physical size of that component, causing said computer to:
for each of said components, electronically determine a collision plot that is larger than the virtual representation of that component and that represents a region within which that component exerts a non-mechanical influence on other components;
electronically logically link the collision plot for a component to the virtual representation of that component;
at a display, visually display the collision plot for a first of said components together with the visual representation for the first of said components;
at said display, allow manual movement at the visual representation of a second of said components with respect to the visual representation of the first of said components to identify an acceptable position of said second of said components relative to said first of said components in the ITE hearing aid; and
provide a visual indication at said display of an unacceptable relative position if said virtual representation of said second of said components invades said collision plot of said first of said components.
