Abstract: A pet toy with one or more treat holding receptacles is provided. A receptacle generally conforms to the outer surface or shape of the pet toy, and extends into the interior of the pet toy for holding a primary treat. The receptacle has a plurality of interior engaging surfaces that frictionally hold the primary treat in a desired orientation. An opening is formed through the receptacle for loading secondary treats into an interior of the pet toy. The primary treat has an exposed portion shaped and sized to provide a desired degree of difficulty for an animal to remove the primary treat from the corresponding receptacle. The portion of the primary treat in contact with the engaging surfaces of the receptacle forms a cap or closure, and when all or part of the primary treat is removed, the secondary treats may be dispensed through the opening of the receptacle.

Abstract: A device to transmit an audio signal comprises at least one light source configured to transmit the audio signal with at least one wavelength of light. At least one detector is configured to detect the audio signal and generate at least one electrical signal in response to the at least one wavelength of light. A transducer is supported with and configured to vibrate at least one of an eardrum, an ossicle or a cochlea. Active circuitry is coupled to the transducer to drive the transducer in response to the at least one electrical signal, so as to provide the user with high quality sound.

Abstract: A deformable membrane assembly comprises an at least partially flexible fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a resiliently bendable supporting ring, a fixed support for the envelope and selectively operable means for causing relative movement between the supporting ring and the support for adjusting the pressure of the fluid in the envelope, thereby to cause the membrane to deform. The bending stiffness of the ring varies round the ring such that upon deformation of the membrane the ring bends variably to control the shape of the membrane to a predefined form. The moving means comprise a plurality of ring-engaging members that we arranged to apply a force to the ring at spaced control points.

Abstract: A packet-based video network including: two or more video data sources, each configured to launch video data packets onto the network as multicast data packets each associated with a multicast group identifier corresponding to that video data source; and a video data destination configured to receive and process video data from a video data source by joining a multicast group corresponding to that video data source, and execute a switching operation to switch from receiving video data from a first video data source to receiving video data from a second video data source by leaving a multicast group of the first video data source and joining a multicast group of the second video data source. The video data destination is configured to process video data corresponding to a video frame which, at end of a frame period, represents a most recently received video frame from the first video data source.

Abstract: The present invention is directed to a portable feeding apparatus or bowl, more particularly to a travel feeding apparatus for pets having hinged, collapsible bowls for holding food and water.

Abstract: A device to transmit an audio signal to a user comprises a transducer and a support. The support is configured for placement on the eardrum to drive the eardrum. The transducer is coupled to the support at a first location to decrease occlusion and a second location to drive the eardrum. The transducer may comprise one or more of an electromagnetic balanced armature transducer, a piezoelectric transducer, a magnetostrictive transducer, a photostrictive transducer, or a coil and magnet. The device may find use with open canal hearing aids.

Abstract: The pet toy comprises a body resembling an animal such as a bird with a laser light source mounted in the body. The body is attached to an elongate flexible wand or spring. The opposite end of the elongate wand connects to a base. The base has a plurality of prongs that extend substantially perpendicular to the base. Each prong has a stem and an arm extending substantially perpendicular to the stem. The pet toy is mounted to a corrugated surface having gaps between layers of material, such as cardboard. The prongs are oriented to engage the surface so sufficient frictional engagement is achieved to keep the pet toy mounted when an animal makes contact with the pet toy. In another embodiment the pet toy is a brush with a base and plurality of prongs in the same configuration such that the brush can be mounted flush to the corrugated surface.

Abstract: A pet toy includes an anchor member and at least one ring member connected thereto. The ring member has a noise making device. In one embodiment, the noise producing feature includes a squeaker protected within a housing disposed within the interior of the toy. In another embodiment, the noise producing feature includes multiple layers of material with one of the layers producing sound. When an outer shell of the ring member is deflected or compressed by contact, noise is produced by the noise making device.

Abstract: The present invention provides a deformable membrane assembly 1 comprising an elastic membrane 8 that is held under tension around its edge by a bendable membrane supporting member 2,10, a body of fluid in contact with one face of the membrane, the pressure of the fluid being controllable for adjusting the shape of the membrane, and one or more bending controllers 24 acting on the supporting member 2, 10 to control the bending of the supporting member in response to loading through tension in the membrane. The bending stiffness of the membrane-supporting member 2, 10 varies round its extent to control the profile of the edge of the membrane 8; etc. upon actuation. A variety of different types of bending controllers are disclosed which permit out-of-plane bending of the supporting member 2, 10 but prevent or control in-plane bending or deformation of the supporting member.

Abstract: A pet toy includes a ring shaped peripheral body and an interior dispenser. An interior curved engaging surface of the peripheral body engages an exterior spherical surface of the dispenser. A curvature of the interior engaging surface allows the dispenser to continuously roll or rotate, yet maintain engagement with the peripheral body when the peripheral body is displaced by contact. The dispenser is hollow thereby defining a chamber to receive treats. One or more dispensing openings are provided on the dispenser to selectively dispense treats. The openings can be sized to selectively dispense treats of various sizes and shapes. The invention further includes a method of dispensing treats from a pet toy and a combination comprising the pet toy and selected treats loaded within the chamber.

Abstract: A treat dispensing device has a body and a hollow interior. A plurality of dispensing openings function to dispense treats. A non-adjustable opening is formed on an exterior surface of the body. A sleeve is slideably engaged within a part of the hollow interior of the body. At least one adjustable opening is formed on the sleeve. A user selectively places the pet toy in a first position to cover the adjustable opening with a portion of the body and a second position to expose the adjustable opening. The sleeve may include two sections in which an adjustable opening is formed on each section. A third position of the pet toy is defined by placement of the body relative to the sleeve so an adjustable opening is exposed on each sleeve section. An incremental position is defined by placement of the body relative to the sleeve so at least one adjustable opening is partially or fully exposed. A method includes placement of the device in a selected position to dispense treats at a selected rate for selected treats.

Abstract: The pet toy comprises a body having a chamber that may hold attractants. A plurality of openings in the body enables the aroma of an attractant to escape. One end of the body includes a projection that frictionally engages one end of an extension in the form of an elongate spring. The opposite end of the elongate spring connects to a base. The base has a plurality of prongs that extend substantially perpendicular to the base. Each prong has a stem and an arm extending substantially perpendicular to the stem. The pet toy is mounted to a surface having gaps between layers of material, such as cardboard. The prongs are oriented to engage the surface so sufficient frictional engagement is achieved to keep the pet toy mounted when an animal makes contact with the pet toy.
