Abstract: A modular pet assembly having a pair of end members that define an opening sized and shaped for the entrance and exit of a pet. At least one end member is configured for wall mounting at a selected elevation. A lateral member interchangeably engages between the end members at a plurality of locations for arrangement of the modular pet assembly in a plurality of configurations. The pet assembly assembles into a configuration for accommodating a pet, and disassembles into a configuration for storage and shipping.

Abstract: A level sensing device with a high frequency radar system is provided. The radar system includes a radar high frequency module, a carrier board and a controller. The radar high frequency module is mounted on the carrier board using surface mount techniques. The controller includes a processor and the radar high frequency module has a plurality of components including one or more microwave integrated circuits, a radiating patch antenna, and coupling means for channeling a radiated signal from the patch antenna out of the module. The components are encapsulated to form the module and the coupling means includes a dielectric rod.

Abstract: A radar high frequency module having at least one distance piece mounted at the flat top wall of the shielding cover for supporting the shielding cover on the printed circuit board without mechanical contact of the downwardly extending side walls of the shielding cover with the printed circuit board to allow alignment of a rod antenna to a patch antenna arranged on the printed circuit board with greater precision. The side walls may be fixed to the printed circuit board by a conductive adhesive.
