Abstract: In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

Abstract: A blow-molded plastic structure, such as a tabletop, may include an undercut. For example, the tabletop may include a frame receiving portion and a frame connecting structure with an undercut may be disposed in the frame receiving portion. A portion of the frame may contact or engage the frame connecting structure, such as the undercut, when the frame is connected to the tabletop. In an exemplary embodiment, a first side of the frame receiving portion may include a first frame connecting portion with an undercut and a second side of the frame receiving portion may include a second frame connecting portion with an undercut. The first frame connecting portion with an undercut may be disposed on an opposing surface from the second frame connecting portion with an undercut.

Abstract: In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

Abstract: In one example, a method includes positioning a tool in a mold, forming a parison of melted plastic, closing the mold around the parison and tool such that part of the tool is positioned between a portion of the mold and the parison, creating a blow molded structure by inflating the parison so that the melted plastic comes into contact with an interior portion of the mold and into contact with the tool, and after the mold is closed, operating the tool to form an integral compression molded element within the mold, and a parting line formed by the mold in the blow molded structure forms no part of the integral compression molded element.

Abstract: A file system for nonvolatile memory media is disclosed, based on the assumptions that the file system structure is flat (i.e., does not contain directories), and that a relatively small amount of memory space is available. The nonvolatile memory medium is divided into logical blocks of predetermined size, depending on the typical file size expected for each particular implementation. Each of these logical blocks includes a header describing the contents of the block. For example, the block header may comprise a magic number indicating whether the block is a valid file system block or a free block, the name of the file to which the current block belongs, a flag indicating whether the current block is the first or last block of the file, the block number of the next block of the current file, if any, and the length of valid data in the present block.

Abstract: A method and apparatus for protecting secured files stored on a file system employs a file security status associated with each file to signal whether or not access to the file is allowed. The file security status is stored in a fixed location in memory. Upon opening the associated file, the file security status is copied to a second location in memory. Depending upon the file security status stored in the second location, operations on the file by a client are either allowed or denied. Operations on non-secure files are always allowed. Operations on secured files are allowed only after verification of the client's authorization to access the file and the subsequent modification of the file security status stored in the second memory location. The method protects secured files from deletion by unauthorized clients. This is accomplished by, upon opening a secure file, initializing a third memory location to a value indicating that the file will not be deleted upon closing.

Abstract: A deformable basketball goal support structure configured to selectively engage a rigid upright member and allow for adjustment of the height of a basketball goal above a playing surface. The basketball goal support structure has a backboard and an attachment member configured to selectively connect the goal support structure to the upright member. At least one support arm pivotally attaches between the attachment member and the backboard. Preferably, a pair of first support arms and a pair of second support arms pivotally attach between the attachment member and the backboard. The backboard includes a support frame having an internal periphery sufficient for receiving at least a portion of the attachment member and the support arms.

Abstract: A mounting assembly for permanently mounting a basketball goal assembly is provided. The mounting assembly may include a base plate with holes configured to fit over retaining members, which may take the form of J-bolts. The mounting assembly preferably has a shorter span of base plate material located between holes on the front side of the base plate, so that bending of the base plate is reduced and vibration of the backboard is not sufficient to disturb game play. The span may be shortened by providing an intermediate support member underneath the base plate, positioned between the front holes, by making the front holes closer together, by affixing the pole toward the front end of the base plate, or any combination thereof. Preferably, the front holes are elongated to form slots so that the front end of the base plate can rest on the ground while the basketball goal assembly is pivoted into position over the retaining members.
