    Abstract: An energy conversion and transmission device is disclosed which, in its preferred embodiment, has a rigid substrate with a resistive area printed on its top surface, a spacer of non-conductive material with an aperture therethrough positioned in register with the rigid substrate resistive area, and a flexible substrate with a resistive area printed on its bottom surface in register with the aperture and the rigid substrate resistive area so that application of a force to the flexible substrate with an elastomeric actuator will move the flexible substrate resistive area to establish an electrical contact area with the rigid substrate resistive area, which electrical contact area increases and, thus, the resistivity of that area decreases as the applied force increases. Thus, when an electrical potential is applied across the two resistive areas, current flow through the two resistive areas increases as the applied force increases. Capacitive, inductive and other embodiments of the device are also disclosed.

    Abstract: A pressure transducer device particularly useful in an electronic musical instrument includes a flexible base folded to define upper and lower flexible base portions, a donut-shaped first spacer between the upper and lower base portions and a resiliently deformable diaphragm attached about its periphery to the upper flexible base portion with a second donut-shaped spacer therebetween. A center region of the diaphragm laterally spaced from the second spacer is adhesively attached to a central region of the upper flexible base portion so that the upper flexible base portion moves inwardly and outwardly in response to the movement of the diaphragm. A pair of conductors are disposed on the folded flexible base member to face one another. A pressure responsive composition disposed over the conductors provides a contact resistance across the pair of conductors which varies inversely with the amount of pressure force exerted against the diaphragm. The upper flexible base portion may be attached between the first and second spacers about its entire periphery or at a small hinge region with the upper base portion being a flap movable about the hinge region in the region surrounded by the first spacer.

    Abstract: One variation of a keyboard system includes: a substrate including an array of inductors; a tactile layer arranged over the substrate defining an array of key locations over the array of inductors; an array of magnetic elements, each arranged within the tactile layer at a key location configured to inductively couple to an adjacent inductor and configured to move relative to the adjacent inductor responsive to application of a force on the tactile layer at the key location; and a controller configured to read electrical values from the inductors. In response to detecting a change in electrical value at a first inductor, the controller also configured to: register a first keystroke of a first key type associated with a first key location defined over the first inductor; and drive an oscillating voltage across the first inductor to oscillate the tactile layer over the substrate during a haptic feedback cycle.

    Abstract: One variation of a system for a haptic actuator includes: a substrate; a baseplate; a magnetic element; and a set of spacer elements. The substrate includes: a first layer including a first spiral trace coiled in a first direction; and a second layer. The second layer is arranged below the first layer and includes a second spiral trace: coiled in a second direction opposite the first direction; and coupled to the first spiral trace to form an inductor. The substrate further includes terminals arranged about a periphery of the substrate and coupled to the inductor. The baseplate is arranged opposite the substrate. The magnetic element is: arranged on the baseplate; and defines a first polarity facing the inductor. The first set of spacer elements are: interposed between the baseplate and the substrate; arranged proximal edges of the baseplate; and defines a nominal gap between the magnetic element and the inductor.
