Abstract: An eyelash application practice apparatus has a head with a face section and a base for supporting the head. The face section has a plurality of eye zones. The eye zones include a plurality of displaceable parts including at least one eyelid with a closure mechanism that allows the at least one eyelid to be displaced to one of a plurality of discrete positions between a first open eye position and a second closed eye position.

Abstract: The present invention relates to an eyelash application practice apparatus. The practise apparatus comprises a head with a face section and a base for supporting the head, the face section has a plurality of eye zones; wherein the eye zones include a plurality of displaceable parts including at least one eyelid with a closure mechanism that allows the at least one eyelid to be displaced to one of a plurality of discrete positions between a first open eye position and a second closed eye position.

Abstract: Methods and structure are disclosed for normalizing storage performance across a plurality of logical volumes. One embodiment is a storage controller. The storage controller is adapted to couple with a plurality of host systems and a storage device. The storage controller is adapted to receive one or more requests to create logical volumes for the plurality of hose systems, and adapted to identify a plurality of performance zones for storage areas of the storage device. The performance zones exhibit different performance criteria for one or more of: reading data from the storage device and writing data to the storage device. The storage controller is further adapted to allocate storage from each of the plurality of performance zones for each of the plurality of logical volumes such that the performance criteria for accessing the storage device is distributed substantially uniformly across the plurality of logical volumes.

Abstract: A Point-to-point protocol configured to provide communication exchange between a first device and a second device. The point-to-point protocol is configured to negotiate an exchange rate and establish a connection for the communication exchange between the first and second device. As system dynamics change, the point-to-point protocol is also configured to permit application programs in the first device and the second device to request renegotiation of the exchange rate at any time. The point-to-point protocol is also configured to provide confirmation to a sending application program that information was delivered to a receiving application program.
