Combining inheritance with the module pattern

I like the module pattern that returns constructors as described in: http://elegantcode.com/2011/02/15/basic-javascript-part-10-the-module-pattern/

However I am not sure how to inherit from an object that is implemented with this pattern. Suppose I have a parent object implemented thus...

namespace('MINE');  

MINE.parent = (function() { 
    // private funcs and vars here

    // Public API - constructor
    var Parent = function (coords) {
       // ...do constructor stuff here
    };

    // Public API - prototype
    Parent.prototype = {
       constructor: Parent,
       func1:  function ()    { ... },
       func2:  function ()    { ... }
    }

    return Parent;
 }());

How do I define a child object that also uses the module pattern that inherits from parent in such a way that I can selectively override, for example, func2 ?

---

MINE.child = (function () {

  var Child = function (coords) {
    Parent.call(this, arguments);    
  }

  Child.prototype = Object.create(Parent.prototype);

  Child.prototype.constructor = Child;
  Child.prototype.func2 = function () { ... };

  return Child;

}());

---

I find the solution from this blog (http://metaduck.com/08-module-pattern-inheritance.html) cleaner. For example:

function Parent(name) {
    // Private variables here
    var myName;

    // Constructor
    myName = name;

    // Public interface
    return {
        func1: function () {alert("Parent func1. Name: " + myName); },
        func2: function () {alert("Parent func2. Name: " + myName); }
    }
}

function Child(name) {
    // Private variables here
    var myName,
        exportObj;

    // Constructor
    // Inherit
    exportObj = Parent(name + "'s father");

    // Override
    exportObj.func2 = function () {
        alert("Child func2. Name: " + name);
    }

    // Export public interface
    return exportObj;
}

An example can be run here: http://jsfiddle.net/wt4wcuLc/
