Abstract: An animal collar includes a collar portion including a housing portion and a plurality of extension portions. Each extension portion can include an insert having a snap receiver aperture extending through the extension portion, as well as a strap receiver having a strap insertion slot and a snap fitting. The snap fitting includes a cap retention slot and one or more snap extensions positioned to engage an interior circumferential ridge of the snap receiver aperture when the snap fitting is inserted into the snap receiver aperture from the first side. The extension portion further includes a retention cap insertable into the snap receiver aperture from the second side and including at least one cap retention extension mateable with the cap retention slot and at least one cap extension positioned adjacent the one or more snap extensions.

Abstract: A system and apparatus to track and control an animal, including a tracking unit to track the animal, and a stimulus unit to provide a stimulus to the animal, wherein the tracking unit and stimulus unit are configured to be removably coupled together, and the tracking unit and/or stimulus unit communicate with a common control device.

Abstract: A button assembly for selectively actuating a switch. The button assembly (10) includes a button member (16) for being mounted in an opening of a housing. The button member (16) is fabricated of a resilient material and defines an outer surface (38) that can be depressed to bring the button assembly (10) into contact with the switch for purposes of actuating the switch. The button assembly (10) also includes a compression ring (26) for being received in a bore (28) provided in the button member (16) whereby the compression ring (26) compresses the button member against the edges of the housing that define the opening in the housing creating a substantially liquid impervious seal and holding the button assembly (10) in place in the opening.

Abstract: An antenna mounting for an animal collar including an O-ring and associated retainer disposed in an opening through the housing of a radio frequency receiver. The O-ring is compressed into multiple sealing locations between the circumference of the antenna and its surrounding structure to create a resilient hermetic seal between the antenna and such surrounding structure, and to resiliently suspend the antenna within the opening in the housing.
