Abstract: An apparatus having a control circuit including a computer processor and a computer memory configured with computer software. The control circuit causes a first test assembly to conduct an initial test of the air pressure within an inner chamber of a first tennis ball; and if the control circuit determines that the air pressure is below a threshold, a pressurization process increases the air pressure inside the inner chamber of the first tennis ball by piercing the outer skin of the first tennis ball with a needle, until a tip of the needle is in the inner chamber, and a first opening, plugged by the needle, is formed in the outer skin of the first tennis ball. The needle tip is thereafter withdrawn from the inner chamber of the first tennis ball, leaving the first opening unplugged and sealant is applied to the first opening to close the first opening.

Abstract: An attachment apparatus; and a band apparatus including a first band. The attachment apparatus may include a first part; and a strap, wherein the strap is configured to removably attach the first part to a person's first body part. The first part of the attachment apparatus includes a body portion; a post projecting out from the body portion; and a loop connected to the post, wherein the loop is configured to be attached to the first band. The band apparatus may include a first ring which is attached to the loop of the first part to thereby attach the first band to the loop through the first ring. The attachment apparatus is attached to the first body part of the person; the band apparatus is connected to the attachment apparatus; and the first band of the band apparatus is stretched, to provide exercise for the person.

Abstract: A stud finder including a magnetic device, a first housing in which the magnetic device is located, and a second housing having a flat surface, and fixed to the first housing. The magnetic device may be configured to move freely within the first housing when the magnetic device is not being held in an orientation and in a position with respect to the first housing by magnetic attraction to an object. The magnetic device may be configured to not move freely within the first housing when the magnetic device is being held in an orientation and in a position with respect to the first housing by magnetic attraction to an object. The magnetic device may have a top surface, and a peripheral surface, which may be at an angle with respect to the top surface. The top surface may have a substantially different appearance from the peripheral surface.

The device may connect the first speaker or front speaker, and the second speaker or rear speaker, so that the device can be attached to an ear of a person so that the first speaker lies near the middle of the ear while the second speaker lies at a location between an ear lobe of the ear and a mastoid of a skull of the person.

Abstract: An apparatus is provided including a main body portion, a first portion connected to the main body portion, and an extension portion connected to the first portion. The extension portion is comprised of an extension arm and a base. The base is configured to slide up and down the extension arm. The apparatus further includes a base engagement means, and a base release. The base engagement means does not allow the base to slide down the extension arm away from the first portion unless the base release has been activated. The base engagement means allows the base to slide up the extension arm toward the first portion regardless of whether the base release has been activated. The apparatus may be used to hang up a picture frame.

Abstract: An apparatus including a cover, a foam housing, a pushing cap, a container, and a seal. The container may be adaptable for retaining a solvent, and the combination of the seal and the container may retain the solvent in a completely enclosed chamber. The seal may prevent the solvent from coming out of the container unless the seal is broken. The cover may be oriented with respect to the pushing cap so that when the cover is pressed in a first direction, the pushing cap moves in the first direction, and snaps into a first position on the container while breaking the seal, and allows the solvent to come out of the container and out of the foam housing.

Abstract: An apparatus including a J-shaped hanger and a first device is provided. The J-shaped hanger may include a hook and a base, the hook connected to the base, the base forming a substantially flat vertical portion of the J-shape, the hook forming the hook portion. The first device may have a first portion having an opening which is large enough so that the base can pass through the opening of the first portion while the base is substantially parallel to the first device. The first device has a front with a first temporary or removable adhesive and a back with a second temporary or removable adhesive. The apparatus can be used for hanging a picture frame.

Abstract: A method is disclosed, which may include attaching an apparatus to a picture frame, and removing an adhesive cover from the apparatus to reveal an adhesive surface. While the apparatus, without the adhesive cover, is still attached to the picture frame, the apparatus can be pressed against a surface of a wall so that the adhesive surface adheres to the surface of the wall. The method may further include detaching a first part of the apparatus from a second part of the apparatus so that the first part of the apparatus remains attached to the picture frame and the second part of the apparatus adheres to the wall. Fasteners may be inserted into the wall using the second part of the apparatus as a guide, and the first part of the apparatus and the picture frame may be hung from the fasteners.

Abstract: A device is provided which includes a cavity containing teeth whitening gel. The device can be attached to a tooth so that the tooth lies inside the cavity and the teeth whitening gel comes in contact with the tooth. The device may includes a plurality of sections, each of which may be designed to attach onto a corresponding single tooth. Each of the plurality of sections may have a width and a length which are about the same as the width and the length, respectively, of its corresponding single tooth. The device can be compressed, expanded, or flexed, so that the device can fit different sets of teeth for different individuals. The apparatus may further include a protective covering for sealing the gel inside the cavity.
