Abstract: A contact lens contains an inward pointing camera, which will be referred to as a retinal camera since it images light reflected from the retina. These can be reflections of physical features of the retina, of images of an external scene imaged by the eye onto the retina, or images projected onto the retina for example from small projectors contained in the contact lens (femtoprojectors). The field of view (FOV) of the retinal camera is sufficiently large that these reflections can be tracked relative to each other and/or relative to their position within the retinal camera's FOV. This information can be processed to track eye gaze and movement relative to the outside world, to align images from the femtoprojector with the eye and/or to align images from the femtoprojector with images from the outside world, among other tasks.

Abstract: A bird blinder apparatus includes a blinder member for blocking views from eyes of a bird. A support member is connected to the blinder member for supporting the blinder member. The support member includes lock-member-reception channels. Flexible lock-member support arms are connected to the support member, and lock members are connected to the flexible lock-member support arms. The lock members include nostril entry ends. The lock members are received in the lock-member-reception channels, and the nostril entry ends extend into nostrils in the beak of the bird for locking the bird blinder apparatus onto the beak of the bird. The bird blinder apparatus of the invention provides a one-piece device that can be installed on the beak of a bird, by one hand of a user, without the need for a separate locking ring and without the need for a separate installation tool.

Abstract: An apparatus for maintaining the eyes of an animal, such as a dog or cat, closed during surgery to keep the surface of the eyes moist. The apparatus includes a collar, a head pad connected to the collar and positioned between an animals ears on its forehead, and a pair of straps also connected to the collar positioned to extend from beneath the animal's chin over the animal's eyes and to be fastened to the head pad. The head pad and straps cooperate to pinch or force together loose skin above and below the eyes to close the eyelids and prevent drying out thereof. A lead line extending from the collar attaches to a non-movable structure so that when the animal awakens, the movement of the animal pulls the collar loose from around the neck.

Abstract: A device for feeding and observing flying animals comprising a hat, a support mounted on the hat and extending outward from the hat, and a feeder mounted on the support. When flying animals feed from the feeders, a person wearing the hat may observe them from a short distance. The device may comprise a helmet with three poles mounted on it and extending outward from the helmet, and a feeder hanging from each of the poles. A variety of flying animals, including butterflies, hummingbirds, and other small birds, may be observed with the device.

Abstract: Improved anti-pecking devices, particularly for poultry and game birds, comprise a pair of limbs having end portions of reduced cross section which engage the nostrils of the bird or other animal, at least one bit member connecting the limbs, and a guard member which projects forwardly from the limbs beyond the end of the beak of the bird. The forward end of the guard may be split. The device may further include resilient bias members which bear upon the upper surface of the beak, in use. Other variations include guard members which extend laterally outwards from the sides of the limbs and multiple bit members spaced apart along the length of the device. The size and configuration of the device and its constituent parts may be varied to suit different sizes and species of bird. The devices are configured to be stackable, such that they may be stored in a cartridge or magazine for application using an automated fitting device.

Abstract: A veterinary oral speculum for use with a bird is a rod having a cut away portion formed in a first longitudinal surface near one end of the rod and defining a handle at the opposite end of the rod. A slotted hole is formed in an opposite second longitudinal surface of the rod. The slotted hole and the cut-away portion are opposed to and communicate with one another and form a through opening in the rod. The speculum is inserted between the mandibles of the bird, rotated through 90.degree. and slid within the mouth of the bird so that the slotted hole is oriented inwardly toward the bird, the cut away portion is oriented outwardly from the bird and the through opening is oriented between the mandibles as a window such that oral access to the bird is gained by the through opening.

Abstract: A poultry feed restraint is disclosed and is adapted to control the eating habits of a selected bird. The restraint comprises an elongated, resilient body that penetrates the beak of the bird. The restraint is inserted through the bird's nostrils or nares to a midpoint. Then the restraint is rotated from the insertion position to a deployed position. A pair of opposing ramps rest upon the exterior of the beak to secure the restraint. A groove defined between the ramps facilitates the rotary movement of the restraint. The restraint prevents the bird from inserting its head into a feeder equipped with a guard or grill. The restraint may be used as part of a system to effectively control the consumption of feed by selected birds. In the system, a feeder with a grill disposed over its top is used. The grill has a predetermined access gap between its bars so that the unselected birds may eat freely from it.
