Abstract: Implementations described and claimed herein provide systems and methods for resisting intrusion by a pest. In one implementation, a reservoir extends between a proximal end and a distal end, and the reservoir defines an interior. A basin is mounted to the reservoir. The basin has a basin body and a basin surface. A sleeve assembly has a sleeve body and a port defined in the sleeve body. A tensioner translationally mounts the sleeve body relative to the basin body. The sleeve body translates distally from an accessible position to an occluded position when a weight applied to the sleeve assembly exceeds a weight threshold set by the tensioner. The accessible position includes bird food on the basin surface being accessible through the port. The occluded position includes the port being disposed distal to the basin surface such that the bird food on the basin surface is inaccessible through the port.

Abstract: A perch extension for a bird feeder having an elongated perch body that defines a cavity that is adapted to fit at least partially over a perch on a bird feeder. The perch extension may optionally have a support member that is coupled to the perch body, and is further adapted to fit at least partially around the seed container of the bird feeder. The perch extension may optionally define protuberances to provide a snap-fit or press-fit engagement with the bird feeder perch.

Abstract: Implementations described and claimed herein involve an easy fill bird feeding system. In one implementation, a depression is received of a release button on a cap assembly connected to a body defining a reservoir. The cap assembly has a cap opening providing access to the reservoir. A lid of the cap assembly is released at a first side upon the depression of the release button. The lid is moved from a closed position to an open position using a bias of a spring assembly upon the release of the lid. The lid moves from the closed position to the open position along a rotation path created by a hinge at a second side. The lid is held in the open position by the spring bias, and the open position provides access to the reservoir through the cap opening. Birdseed is received through the cap opening into the reservoir.

Abstract: A fetal electrode assembly including a housing having a first opening for receiving a first connector and a second opening for receiving a second connector. The second connector is a snap connector of an electrode mounted on a mother's body. A support is disposed within the housing and has an access opening communicating with the second opening. A contact is mounted on the support opposite the second opening. The contact includes a pair of spaced, resilient members adapted to resiliently engage and make electrical contact with the snap connector. In one aspect of the invention, the contact is bent to define a pair of parallel spaced apart legs, one end of each of the legs being interconnected by a resilient loop portion, the other ends of the legs being free.

Abstract: A fetal electrode assembly for use in monitoring fetal heart rate and used in conjunction with a fetal monitor coupling device supported on the mother's body. The assembly including fetal and maternal electrodes secured to an insulating holder, a connector dimensioned and shaped to be received in an opening in a coupling device housing and having first and second contacts separated and electrically isolated from each other and positioned to make electrical contact with complementary contact members in the coupling device. An insulated pair of elongated flexible wires, each electrically connecting a respective one of the first and second contacts to a respective one of the fetal and maternal electrodes. An elongate tubular sheath covers the connector and has a first open end extending over and receiving the ends of the pair of flexible wires, the opposite end of the sheath being spaced from each of the electrodes.
