Abstract: A bird feeder has a tubular body member having an open bottom end. A base member interfittingly engages the bottom end of the tubular body member The base member is releasably secured to the tubular body member by the engagement of a spring-biased pin that communicates with an aperture through the wall of the tubular body member. Preferably, there are two spring-biased locking pins on opposing sides of the feeder with corresponding lock eye apertures. User manipulatable buttons, which are mechanically linked to the locking pins, are depressed to cause the locking pins to retract to permit releasable attachment of the tubular body member of the feeder thereon enabling easy access to the interior of the feeder.

Abstract: A nectar feeder for birds has a body member with a base and a lid. The base has an open top end and a side wall. The lid is interfittingly engaged with the top end of the base. A hinge connects the lid to the base to allow movement of the lid relative to the base. The lid has a support extending from an upper surface of the lid. At least one feed port, preferably three, is defined through the lid. The feed port and the support are substantially aligned on the same horizontal plane. A latch is attached to the upper surface of the lid to prevent movement of the lid relative to the base. A moat optionally extends about the periphery of the body member.

Abstract: The present invention is a nectar feeder for birds. The nectar feeder has a container for storing nectar feed. A base tray is attached to the container and connected in fluid communication with the container. A float is positioned between the container and the base tray. A ball is positioned on the float. The ball regulates the fluid communication between the container and the base tray. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the ball prevents fluid from flowing into the base tray.

Abstract: An antenna arrangement including a first antenna module having a first antenna loop positioned in a plane for emitting a signal in a first spatial area, and at least one additional antenna loop positioned in substantially the same plane for emitting a signal in an additional spatial area. The arrangement includes at least one power source in communication with the first antenna module for providing current thereto. The first spatial area and the additional spatial area at least partially overlap, and the first antenna loop and the additional antenna loop are powered by the power source in a specified pattern. A method of identifying at least one item is also disclosed.

Abstract: A powder sinter layered manufacturing apparatus is provided with a first container 13 of a cylindrical shape for defining a first manufacturing region, a first manufacturing table 15 configured to move vertically along an inner wall of the first container 13, a second container 17 of the cylindrical shape for defining a second manufacturing region within the first manufacturing region, detachably fitted to the first container easily, and provided with a flange which covers an upper face located outside the second manufacturing region but inside first container 13, and a second manufacturing table 15b configured to move vertically up and down along an inner wall of the second container 17.

Abstract: The present invention is generally directed to a novel and unique bird feeder base that includes a main body having a bottom edge where the bottom edge defines a bore having an inner surface. The inner surface of the bore has at least one female thread member residing and extending less than 360 degrees about such inner surface. Most importantly, the female thread member can be formed without the need for time consuming drilling and tapping. In addition, the bore and female thread member on the inner surface thereof is threadably engagable with a male threaded accessory, such as a mounting post, seed tray or squirrel guard.

Abstract: A removable seed deflector for a bird feeder is disclosed that can be installed into the bottom open bottom end and a side wall of the bird feeder. A base member interfittingly engages the bottom end of the tubular body member. The base member includes at least one aperture defining at least one seat, respectively. The base member is releasably secured to the tubular body member of a feeder. A seed deflector is releasably secured to the base member and includes at least one downwardly depending leg that releasably engages with the seats, respectively, in the base member.

Abstract: An antenna arrangement including a first antenna module having a first antenna loop positioned in a plane for emitting a signal in a first spatial area, and at least one additional antenna loop positioned in substantially the same plane for emitting a signal in an additional spatial area. The arrangement includes at least one power source in communication with the first antenna module for providing current thereto. The first spatial area and the additional spatial area at least partially overlap, and the first antenna loop and the additional antenna loop are powered by the power source in a specified pattern. A method of identifying at least one item is also disclosed.

Abstract: The present invention includes a method of filling a nectar bird feeder. The bird feeder includes a base with a nectar reservoir and an extension member that downwardly depends from the bottom surface thereof. A hanger is connected to the base and extends upwardly therefrom. A cover, which is releasably attached to the base, has a central aperture to receive the hanger therethrough. The cover is removed from the base and placed on a support surface. The base is then placed on the cover with the extension member being positioned through the aperture so it can be movably positioned so it is level for filling of the reservoir of the base with nectar. After filling, the base is removed from the cover and the cover is reattached to the base.

Abstract: A wireless networked monitoring system including multiple reader mechanisms for receiving, processing and transmitting signals, each reader mechanism associated with a read zone. Multiple signal emitting devices or tags are positionable within the read zones and emit signals containing data. A central processing device is in wireless communication with the reader mechanisms and receives, processes and transmits signals. In addition, the central processing device communicates with and controls the reader mechanisms and/or signal emitting devices.

Abstract: An identification apparatus for use in connection with a plurality of discrete identity source elements positioned in an identification apparatus signal identification area. The identification apparatus includes a plurality of signal receiving mechanisms forming a first signal receiving module and each of the signal receiving mechanisms having a respective field of detection, each of which comprises at least a portion of the identification apparatus signal identification area and at least partially overlaps another field of detection. Each signal receiving mechanism is individually powered in a specified pattern, and the first signal receiving module moves along an axis of movement. A control mechanism in communication with the signal receiving module.
