Abstract: An improved safety valve for a toy air gun apparatus in which the toy air gun includes a piston and a drive spring mounted in a grip portion of the air gun. A handle extends from the bottom of the grip portion and is manipulated by the user to cock the air gun by compressing the drive spring. When the user pull a trigger the piston is released and surges upward because of the expanding drive spring. A valve element located to the rear of a barrel section of the air gun receives a blast of compressed air in a direction lateral to the longitudinal axis of the valve element and lateral to valve element movement between an open, rearward position and a closed, forward position.

Abstract: A display system is disclosed that is capable of switching between graphics processing units (GPUs). Some embodiments may include a display system, including a display, a timing controller (T-CON) coupled to the display, the T-CON including a plurality of receivers, and a plurality of GPUs, where each GPU is coupled to at least one of the plurality of receivers, and where the T-CON selectively couples only one of the plurality of GPUs to the display at a time.

Abstract: An adapter including an associated battery capable of powering an electronic device. The power adapter typically includes the battery as an integral component that is connected to a plug or other interface capable of mating with a power source, such as a wall socket. Thus, the adapter battery may provide power either to operate the device or charge a battery within (or otherwise associated with) the device even if the adapter is not connected to a power source.

Abstract: An air gun toy which has a housing mounting a cylinder and a piston for compressing air to cause foam darts to be discharged. The air gun includes the piston, a first connector pivotally connecting a first link to the piston, a second connector pivotally connecting the first link to a second link, a third connector pivotally connecting the second link to housing, a main spring and a trigger. When the piston reaches its forward position, the first, second and third connectors align in a linear configuration, like a toggle joint, to brace the piston and prevent piston bounce back.

Abstract: A system and method efficiently manage clones of an object group. A base storage area contains metadata for each of multiple objects in the object group. The metadata for each object identifies data within each object. The system receives a request to clone a base storage area, and in response, the system creates a clone storage area containing an identification of the base storage area but not the metadata. If there is a subsequent request to update a portion of one of the objects, then the system copies the portion, copies the metadata into the clone storage area for the one object, makes the update to the object copy and changes the metadata in the base storage area to identify the portion copy instead of the original portion. If there is no subsequent request to update any of the multiplicity of objects, then the system does not copy the metadata for any of the multiplicity of objects into the clone storage area.

Abstract: A computer system manages first and second different file systems. The system comprises first and second, different file managers having first and second different APIs for the first and second file systems, respectively. The system also comprises a hybrid file manager for managing the second file system based on requests made using the first API. The hybrid manager applies rules from both APIs to control atomicity of requests, access concurrency, and data consistency rules. The hybrid rules prevent violation of the rules of either API.

Abstract: A file management and backup system manages access to data objects such as records stored in a primary repository, and occasionally backs-up the data objects to a backup repository. A backup utility within the system, periodically or at the request of a user, makes a backup request to a file manager, and specifies the scope of the backup. In response, the file manager makes an entry in a "backup in progress" table indicating that the corresponding file space(s), directory(ies), file(s) and/or data object(s) are currently involved in a consistent backup procedure. Then, the backup utility commences the actual copying of the data within the backup scope to the backup repository with assistance from the file manager in accessing the data from the primary repository.
