Abstract

Two inductors formed in multiple layers of conductive layers of integrated circuits are disclosed. Symmetric portions of a first inductor and a second inductor are formed in two or more conductive layers. Portions of the first inductor in adjacent conductive layers are connected by vias, and portions of the second inductor in adjacent conductive layers are connected by vias. The first and second inductor portions form a substantially loop-shaped structure in each conductive layer. The first and second inductor vias may be positioned at the same position within the substantially loop-shaped inductor structure by alternating inner and outer radiuses, or the vias for the second inductor may be positioned opposite the vias for the first inductor within the substantially loop-shaped inductor structure, using notches in the first and second inductor portions.

Claims

1. An aerosol assembly for dispensing texture material on a target surface in two or more spray patterns, where each spray pattern corresponds to a texture pattern, comprising:

a container;

a valve assembly comprising

a valve housing defining an inlet opening and an outlet opening,

a valve seat defining a seat opening, where the valve seat is held between container and the valve housing such that the valve housing and the valve seat define a valve chamber,

a valve member defining a stem recess, where the valve member is disposed within the valve chamber such that the stem recess is accessible through the seat opening, and

a valve spring arranged within the valve chamber, where the valve spring is configured to bias the valve member against the valve seat to place the valve assembly into a closed configuration,

an actuator member defining a stem portion and a head portion, where an inlet slot is formed in the stem portion, an actuator outlet is formed in the head portion, and an actuator passageway extending between the actuator inlet and the actuator outlet;

at least one outlet member defining two or more outlet opening cross-sectional areas, where

each outlet opening cross-sectional area corresponds to one of the spray patterns, and

one of the outlet opening cross-sectional areas is selected such that the texture material is deposited on the target surface in a texture pattern that substantially matches a predetermined texture pattern; and

a collection tube that extends from the valve housing into the container;

whereby

the stem portion of the actuator member engages the stem recess formed in the valve member to fix the actuator member relative to the container during normal use of the aerosol system;

applying a force to the actuator member compresses the valve spring to place the valve assembly into an open configuration;

when the valve assembly is in the closed configuration, fluid is substantially prevented from flowing through the actuator passageway; and

when the valve assembly is in the open configuration, fluid may flow out of the container through the actuator passageway the selected one of the outlet opening cross-sectional areas.

2. An aerosol assembly as recited in claim 1, in which the at least one outlet member comprises a plurality of tubular members each defining one of the outlet opening cross-sectional areas, where one of the tubular members is selected to select the selected outlet opening cross-sectional area.

3. An aerosol assembly as recited in claim 2, in which a bore in the actuator member frictionally engages the selected tubular member to secure the selected tubular member to the actuator member.

4. An aerosol assembly as recited in claim 1, in which the outlet member comprises an outlet plate defining the outlet opening cross-sectional areas.

5. An aerosol assembly as recited in claim 4, in which the outlet plate is rotatably attached to the actuator member such that the outlet plate may be rotated to cause the selected outlet opening cross-sectional area to be in fluid communication with the actuator outlet.

6. An aerosol assembly as recited in claim 1, in which the outlet member comprises a resilient member defining the at least one outlet passageway, where the resilient member is deformed to select a selected outlet opening cross-sectional area.

7. An aerosol assembly as recited in claim 6, further comprising a collar movable mounted on the actuator member, where movement of the collar relative to the actuator member deforms the resilient member.
