FLUIDIC METHODS AND DEVICES

摘要

A device for use by an individual for sexual pleasure varying in form, i.e. shape, during its use and allowing for the user to select multiple variations of form either discretely or in combination and for these dynamic variations to be controllable simultaneously and interchangeably while being transparent to the normal use of the device, including the ability to insert, withdraw, rotate, and actuate the variable features manually or remotely. According to embodiments of the invention localized and global variations of devices are implemented using fluidics and electromagnetic pumps/valves wherein a fluid is employed such that controlling the pressure of the fluid results in the movement of an element within the device or the expansion/contraction of an element within the device.

主权项

1. An electromagnetic pump comprising:
a piston formed from at least a first magnetic material having a first length and a first predetermined lateral dimension; a bobbin case formed from a first predetermined material having a second length comprising an inner shell defining a central bore of a second predetermined lateral dimension and having an electrical coil formed from a second predetermined material of predetermined diameter disposed around the inner shell; first and second assemblies disposed at each end of the bobbin case wherein each assembly comprising the following elements disposed in sequence away from the bobbin case and in physical contact with each other:
an inner washer having a first thickness with an inner bore of a third predetermined lateral dimension formed from a third predetermined material that is either ferromagnetic or paramagnetic and having a projection upon the surface towards the bobbin case having a third length with an inner bore of the third predetermined lateral dimension and a predetermined width;a magnet formed from a second magnetic material having a second thickness with an inner bore of a fourth predetermined lateral dimension;a magnet casing formed from a fourth predetermined material having the second thickness and an inner bore to allow the magnet to fit within the magnet casing; andan outer washer having a third thickness with an inner bore of a fifth predetermined lateral dimension and being formed from a fifth predetermined material; and a body sleeve formed from a sixth predetermined material having:
an inner bore having a predetermined tolerance with respect to the first predetermined lateral dimension of the piston and an outer profile defined centrally by the first predetermined lateral dimension and first length of the central bore of the bobbin case and then axially away in either direction by the third predetermined lateral dimension together with the first thickness and the second length of the inner bore of the inner washer, the second thickness and fourth predetermined lateral dimension of the inner bore of the magnet, the third thickness and fifth predetermined lateral dimension of the inner bore of the outer washer such that these elements are aligned; anda stop at each end having a fourth thickness, an inner bore of a sixth predetermined lateral dimension and a body against an outer surface of the outer washer in order to retain the elements of the first and second assemblies and the bobbin case in physical contact with one another.
