Abstract:
A data storage system which copies data from source data storage volumes to target data storage volumes restricts a write operation to at least one source data storage volume (FREEZE), to prevent the updating of a source while the data of a consistency group of interdependent data is being copied. Program logic selects a source data storage volume to which the restriction applies as a verification volume; and the program logic responds to a verification request to first employ the verification volume to verify that the restriction remains in place with respect to the verification volume, and to allow a reset of the restriction (THAW).
Abstract:
An apparatus, system, and method are disclosed for replicating point-in-time copies of local data to a remote site. The present invention mirrors point-in-time copy directives on the local data store to initiate a point-in-time copy operation on the remote copy of the local data, thereby efficiently providing remote access to a point-in-time copy of a dataset. Data integrity is ensured by committing local and remote point-in-time copy operations subsequent to successful initiation of both local and remote point-in-time copy operations. The present invention also, in one embodiment, rolls back a point-in-time copy operation in response to a failure to replicate the copy operation.

Abstract:
A method and a device are disclosed for an exercise machine having an integrated or removable computing device with a Graphical User Interface (GUI) to enable a user to control and interact with the computing device. In various embodiments, the computing device is configured to access other computers, run software applications related or unrelated to the exercise machine, communicate with other users via voice and/or visual data channels, and substantially perform all functions available using a personal computing device.
Abstract:
A system and method of forming surfaces on eyeglass lenses is described. In some examples, the surface is a spherical, cylindrical or spherocylindrical surface at a center of the lens and an aspherical surface at a periphery of the lens. In some examples, forming the surface on the lens reduces the thickness of the lens at the periphery of the lens.
Abstract:
Embodiments include a system and method for generating RTL description of an electronic device provided for a design test and a test bench environment to drive stimulus into the electronic device, identifying at least one register to be verified during the design test, authoring a property list including a plurality of properties, wherein each property includes a cause and an effect, creating a new property instance upon receiving an enqueue cause, transitioning a property instance from a waiting state to a pending state based on a dequeue cause, advancing property instances from the pending state to an active state and then to an expired state based on a defined time window, creating a current solution space including a plurality of solutions, wherein each of the plurality of solutions includes a list of unused active effects, inserting property instances into each of the plurality of solutions when the property instance enters to active state, pruning solutions from the current solutions space which have not used a property instance entering the expired state, and computing a new solution space based on the current solution space and target transition.
Abstract:
A gardening system includes a modular seed cartridge including a rigid, cup-shaped receptacle including an upper portion having an outer rim, a soilless growth medium located in the rigid, cup-shaped receptacle, and at least one seed in contact with the soilless growth medium. The gardening system also includes an aeroponic or hydroponic garden including a chamber including a lower portion for storing a liquid nutrient solution, a cover located above the chamber, the cover including a plant opening adapted to removably support the modular seed cartridge by the outer rim, and a pump located in the chamber and adapted to circulate the liquid nutrient solution from the lower portion of the chamber to the modular seed cartridge supported by the plant opening.
