Abstract: A modular pet enclosure having interchangeable and configurable wall panels of varying size is provided. The tunnel connection panel can be placed in multiple different configurations and orientations. An open-ended tunnel that can be removably attached to the modular pet enclosure and a dwelling, including all known pet doors, is used for the pet to move between the dwelling and the enclosure.

Abstract: A chip-battery micro-module and fabrication method thereof wherein an integrated circuit "chip" is secured to a battery coin cell using various conductive and insulative layers that provide power to the chip while also forming a protective structure for protecting the chip. The chip-battery micro-module may be used to power an electronic accessory which is directly attached thereto, such as an LCD display or speaker, or to power a circuit in a smart card or electronic device such as a portable telephone. The chip may be secured to the battery using epoxy layers, epoxy bodies, dielectric layers, and plasma- or vapor-deposited layers. The above elements may be conductive or insulative as required. The chip-battery micro-module can be integrated into a plastic smart card. The use of the rigid battery coin cell provides the chip-battery micro-module with improved strength characteristics for withstanding loads and impacts during assembly and handling.
