An integrated rockably released leverage snap fastening system is disclosed herein comprising a male snap and a rockable lever snap assembly wherein the rockable lever snap assembly may be removably fastened to the male snap to hold at least one item in place. To facilitate unfastening, male snap and rockable lever snap assembly cooperatively combine to create a class 1 lever system which may reduce friction and permit a user to rockably release the snap while reducing risk of damage to an item. Various embodiments of the present invention and a method of use are discussed herein.

Methods and apparatus provide an adaptive load balancer that presents a virtual data system to client computer systems. The virtual data system provides access to an aggregated set of data, such as files or web service objects, available from a plurality of server data systems respectively operating within a plurality of server computer systems. The adaptive load balancer receives a client data access transaction from a client computer system that specifies a data access operation to be performed relative to the virtual data system presented to the client computer system. The adaptive load balancer processes the client data access transaction in relation to metadata associated with the virtual data system to provide access to the file or service object within a server computer system, or to access the metadata. The adaptive load balancer can work in conjunction with other adaptive load balancers to dynamically adjust to demands for access to data by replicating and migrating data such as files or service objects as needed between the server computer systems to accommodate data access demands.

Fasteners, and related methods, for securing deck boards to a support joist are disclosed. In one embodiment, the fastener comprises a base portion and a cap portion on the base portion. In some embodiments, the base portion includes an opening formed therethrough for receiving a securing device, and legs extending from an upper surface of the base portion and between edges of adjacent deck boards to define a spacing between the adjacent deck boards. The cap portion can include an opening for receiving the securing device therethrough to secure the fastener to the support joist. In addition, the cap portion may include legs extending around the base portion and comprising teeth extending therefrom that bite into grooves formed in the edges of the adjacent deck boards when the securing device secures the fastener to the support joist, thereby securing the deck boards to the support joist.

A pet grooming tool, for use with a furry pet such as a dog or cat having loose hair and non-loose hair, is adapted for removing the loose hair from the pet. The grooming tool comprises an handle portion and a pet engageable portion secured to the handle portion. The pet engageable portion includes a blade portion and a plurality of teeth. The blade portion includes a blade edge. The teeth extend from the blade edge. The blade edge is adapted to engage the loose hair of the pet and pull it from the pet without cutting or pulling the non-loose hair from the pet.

A filter assembly for treating a compressed gas stream comprises a container which comprises a body and a cap which are sealingly joined to one another at an interface. The body and cap each have a port through which compressed gas can flow. The body contains a quantity of adsorbent material so that gas flowing through the container from one of the ports to the other port flows through the adsorbent material, and a plate located between the adsorbent material and the interface to hold the adsorbent material in place within the body. The cap includes a particle removal filter through which compressed gas passing through the port in the cap will pass, and a skirt which extends into the body to maintain a separation between the plate and the particle removal filter.
