Abstract: The present invention relates to a surveying apparatus for surveying an object as well as a surveying system comprising the surveying apparatus having a simple and compact optical setup. The surveying apparatus comprises a lens arrangement including at least one movably arranged focus lens element for focusing to sight an object; an imaging unit configured to obtain an image of at least a part of the object; a distance measuring unit configured to measure a distance to the object along the optical axis of the distance measuring unit; and a beam splitter/combiner configured to combine a part of the optical imaging path of the imaging unit and a part of the optical distance measuring path of the distance measuring unit so that the optical axis of the imaging unit and the optical axis of the distance measuring unit are at least coaxially arranged with the optical axis of the lens arrangement between the lens arrangement and the beam splitter/combiner.

Abstract: 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: A nectar feeder for hummingbirds is disclosed. The feeder includes a container configured and arranged to store nectar feed. A spout depends from the bottom end of the container with an exit port defined thereon. A base tray positioned below the container and contains nectar feed. A vertical member extends from the base tray. A float engages at least one vertical member to prevent substantial independent lateral movement of the float within the base tray. The float also includes a rounded bottom surface to further help stabilize it on the liquid feed to prevent leaking. The float has a stopper therein positioned below the spout. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the stopper engages the exit port on the spout to prevent fluid from flowing into the base tray.

A spout depends from the bottom end of the container with an exit port defined thereon. A base tray positioned below the container. The base tray is further configured and arranged to contain nectar feed therein. A vertical member extends from the base tray. A float is positioned between the container and the base tray. The float engages the vertical member to prevent substantial independent lateral movement of the float within the base tray. The float carries a stopper with a substantially flush surface positioned below the spout. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the stopper engages the exit port on the spout to prevent fluid from flowing into the base tray.

Abstract: A bird feeder has a body member, a base, and at least one feed port member. The body member is used for storing bird food having a top end, a bottom end and a sidewall with the sidewall of the body member defining at least one feeding aperture. A base is attached to the bottom end of the body member to prevent bird food from exiting the body member. The at least one feed port member is interfittingly engaged within at least one feeding aperture. The port member includes a frame member and a mesh insert attached to the frame member. The feed port member is releasably secured within the feeding aperture of the body member. In operation, the feed port member can be easily removed from the body member for easy cleaning or adapting to a particular bird feeder construction.

Abstract: The invention relates to an electronic distance measuring apparatus for surveying, e.g. for measuring the distance from the apparatus to an object. The apparatus comprises: a) an objective lens (101), defining an optical axis (OA), b) at least two sources (111, 112) of structured light for transmitting beams (?1, ?2) of separate wavelengths towards said object, said beams on reflection from said object received by the objective lens (101), (c) at least two receivers (141, 142) arranged outside a beam path (109) as defined by the objective lens (101), and adapted to receive said received beams (?1, ?2) of structured light.
