  • Patent number: 5814761
    Abstract: A passive Electromagnetic Interference (EMI) dissipation apparatus typically utilized with an active host component to reduce self-generated and externally-generated electromagnetic interference and to improve the performance of the host component is disclosed. The apparatus includes a housing and a circuit located within the housing. The circuit includes a plurality of pyramidal-shaped resonating chambers having internally conductive surfaces covered with a layer of electrically resistive material, a plurality of quartz resonators each mounted upon a damping compound, and a plurality of permanent magnets each including a magnetically permeable bar. The electromagnetic interference is dissipated in the circuit over a broad range of frequencies in the form of heat. In a preferred embodiment, the plurality of permanent magnets and the corresponding plurality of permeable bars are mounted within a common chamber located immediately below the base of each of the pyramidal-shaped resonating chambers.

  • Patent number: 5615640
    Abstract: A pet emergency disaster shelter typically utilized during a natural disaster to provide temporary emergency survival housing to a domestic pet to increase the probability that the pet will survive the disaster is disclosed. The pet emergency disaster shelter comprises a lower base section formed of a moisture-resistant, buoyant shell. The lower base section has a top surface supported by an air mattress positioned within the buoyant shell. The top surface and the air mattress in combination support the weight of the pet. An upper dome section is mounted upon the lower base section for housing the pet. The upper dome section includes a weather-resistant material for providing protection to the pet against a plurality of weather conditions. In a preferred embodiment, the upper dome section is mounted upon and attached to the lower base section in a suitable manner as by adhesives. The top surface of the lower base section is sloped and serves as a floor to the pet within the upper dome section.

  • Patent number: 5579657
    Abstract: An anti-theft device for small portable equipment and method includes at least one conductor extending therefrom having a first end permanently connected to the equipment and a second end formed into a plug for fitting into a receptacle. The anti-theft device comprises a planar disk having a penetration formed therethrough which is large enough to enable the passage of a loop of the equipment conductor but small enough to prevent the passage of the plug. A security cable passes through the loop of equipment conductor extending through the penetration of the planar disk. The security cable is securely anchored to prevent the removal of the loop of equipment conductor from the penetration of the planar disk which prevents the removal of the small portable equipment. The planar disk can be positioned to any location along the equipment conductor and along the security cable. In a preferred embodiment, the planar disk exhibits a flat, elongated shape and the penetration formed therethrough is oval shaped.

  • Patent number: 5560269
    Abstract: A wrench for use with a seized engine oil filter typically employed in a mechanical environment in which a conventional threaded oil filter cannot be removed from an oil lubricated engine. The oil filter wrench comprises a cap-shaped housing including a planar top surface and a wall formed orthogonal to the perimeter of the top surface. A plurality of flat keyed edges formed on an interior surface of the wall are provided for engaging a housing of the oil filter. Several threaded shaft and nut assemblies are mounted to the wall for piercing said oil filter housing. The threaded shaft and nut assemblies lock the cap-shaped housing to the oil filter for maximizing the torque on the oil filter when the cap-shaped housing is rotated. A socket receptacle formed in the planar top surface enables rotation of the cap-shaped housing. In a preferred embodiment, the flat keyed edges formed on the interior surface of the wall enable the cap-shaped housing to be fitted over the edges of a conventional oil filter.

  • Patent number: 5495960
    Abstract: A multi-tier storage apparatus employed in a sales environment for storing and displaying fragile merchandise subject to damage during earthquakes and other natural disasters. The invention includes a first container having a plurality of upright walls and a bottom surface each including a mesh construction which is utilized for storing and displaying merchandise. A horizontal projection extends into the first container from the upright walls. A plurality of second containers are mounted on the horizontal projection for storing and displaying merchandise. Each of the second containers includes a mesh construction and is movable relative to other of the second containers and to the first container along the horizontal projection for accessing the first container. In a preferred embodiment, a first or lower container is formed in a mesh construction and preferably in a rectangular shape.

  • Patent number: 5437068
    Abstract: An inflatable air mattress having a generally rectangular mat portion that is foldable or bendable in multiple directions in a fully inflated condition. The mat portion includes rows of generally sinusoidal seals extending transversely across the mat portion. Alternating rows of the sinusoidal seals are uniformly shifted out of phase by a range of about 1/8 to 3/8 of the repeating period, or a phase shift of from about .pi./4 radians to about 3.pi./4 radians, and most preferably by a phase shift of about .pi./2 radians. Alternating rows of inflation chambers are formed by the sinusoidal seals with enlarged body portions and neck portions of reduced thickness, which form natural fold lines in the mat portion when the mat portion is inflated. The mat portion is bendable longitudinally, transversely and obliquely to be rollable and foldable, and to permit the mat portion to cradle the torso and extremities of a person reclining on the inflatable mattress in water.

  • Patent number: 5326338
    Abstract: A lateral exercise apparatus for use in performing side-to-side skating movements having a surface layer for performing the skating movements on each side thereof. Each side of the surface layer has a very low coefficient of friction. A plurality of adjustable clamps are utilized to adjust the length of the surface layer with each adjustable clamp including at least one pair of releasable clamping surfaces for gripping the surface layer. Each of a plurality of resilient bumpers are removably interlocked to one of the releasable clamping surfaces of each of the adjustable clamps for terminating the side-to-side skating movements. The resilient bumpers are wedge-shaped and have a low impact surface angle .THETA. of less than or equal to 20.degree.. Finally, a high friction layer is provided for underlying and securing the surface layer to a floor surface.
