US Classification:

473290, 473345, 473324, 473349, 473409

Abstract:

A ball striking device, such as a golf club, includes a head with a face having a ball striking surface configured for striking a ball, a main body member connected to the face and having an engagement surface located in the rear side, a removable body member removably connected to the main body member, and a connecting element removably connecting the removable body member to the main body member. The connecting element includes a moveable engaging member that is moveable between a locked position, where the engaging member engages the engagement surface to retain the removable body member to the main body member, and an unlocked position, where the engaging member does not engage the engagement surface and the removable body member is removable from the main body member.

US Classification:

4352872, 422502, 4352891, 422 8205

Abstract:

The present invention relates generally to the control of fluid flow rate and direction on a microfluidic device. In particular, the present invention provides an integrated valveless microfluidic device, where directional fluid control is controlled using off-chip remote valve switching and fluid flow rate changes are controlled using on-chip flow-rate changing fluid reservoirs. The present invention provides methods and systems for directional fluid control and control of fluid flow rate in an integrated microfluidic device which enables processes with different flow rates to be performed on one device without the need of on-chip valves.
