Abstract: An air gun includes a gun barrel through which a bore passes from a breech end to a muzzle end, a piston, and a spring housed within a main housing. The spring biases the piston forward towards the gun barrel. An air compression chamber is defined by a cylindrical interior surface and a forward face of the piston. A cocking mechanism enables a user to forcibly retract the piston rearward from the gun barrel against the spring bias to a cocked position. The main housing includes a rearward cavity that accepts the rearward retraction of at least a portion of the piston, which portion may include a coating of paint. A first viewing port into the rearward cavity may have a translucent cover and visually indicates a state of rearward retraction of the piston.

Abstract: A safety release mechanism for snowboards functions with standard contemporary snowboarding boots and bindings. Bindings that would normally be fastened to the snowboard are instead both fastened to a single binding support platform. A platform retention assembly, fastened to the snowboard, includes preloaded compliant members that form interfaces with contours on the binding support platform. The interfaces prevent the binding support platform from separating from the snowboard except when a force or torque applied to the snowboard exceeds a set threshold. The platform retention assembly also includes firm features that contact firm mating features on the binding support platform to prevent translation of the binding support platform relative to the platform retention assembly in the plane of the snowboard. The firm features and the firm mating features are arranged such that the contacts between them, when projected onto the plane of the snowboard, are all tangent about one mutual center point.

Abstract: A suspension for connecting a slider to an actuator arm of a disc drive includes a cushion extending vertically from the suspension. The cushion limits vertical excursions and dampens motion of the suspension during a shock event to better maintain the slider in contact with a disc surface in the disc drive. The cushion can be formed as an external feature attached to the suspension, such as a foam or plastic cushion, or as an integral feature of the suspension. A disc drive assembly having a plurality of discs includes a first suspension and a first cushion extending vertically downward toward a second suspension. The second suspension may include a second cushion extending vertically upward toward the first suspension.

Abstract: A head suspension assembly for mounting and supporting a head in a disc drive which includes a preloaded gimbal assembly. The preloaded gimbal assembly acts, during certain applied mechanical shock events, to prevent separation of the head and the disc which can lead to damaging contact between the head and the disc. Various design and manufacturing considerations necessary to implementation of the invention are disclosed.
