Abstract: A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

Abstract: A polyimide adhesive composition is a reaction product of polyamic acid and bismaleimide (I) modified by barbituric acid (II) or the derivatives thereof. Once the present composition is directly coated onto copper foil, the bonding force is greatly improved as compared to compositions without (II) or (I) and (II). Therefore, the adhesive normally used in the manufacture of flexible printed circuits boards and tape automated bonding (TAB) is no longer necessary.

Abstract: A nursing bottle system includes axially joined first and second container bodies or portions. The container bodies are liquid tightly separated from one another by a wall extending perpendicularly to the container axis. Different liquid foods can be carried in the container bodies, and fed as desired to an infant through a nipple provided at the open end of the selected container body of the system.
