Abstract: Methods and apparatus for controlling a polyphase motor in implantable medical device applications are provided. In one embodiment, the polyphase motor is a brushless DC motor. The back emf of a selected phase of the motor is sampled while a drive voltage or the selected phase is substantially zero. Various embodiments utilize sinusoidal or trapezoidal drive voltages. The sampled back emf provides an error signal indicative of the positional error of the rotor. In one embodiment, the sampled back emf is normalized with respect to a commanded angular velocity of the rotor to provide an error signal proportional only to the positional error of the motor rotor. The error signal is provided as feedback to control a frequency of the drive voltage. A control generates a speed control signal corresponding to a difference between a commanded angular velocity and an angular velocity inferred from the frequency of the drive voltage.

Abstract: A technique for synchronizing data caches. Data is maintained in the data caches as records. The records are associated with buckets which represent collections of one or more records. The buckets are collectively maintained in a synchronization set which represents a state of a data cache. A local entity synchronizes its data cache with a remote entity by sending its synchronization set to the remote entity in a synchronization request message. The remote entity compares information contained in the local entity's synchronization set with its own to determine if the two are consistent. If not, the remote entity notes inconsistencies in a response message that is then forwarded to the local entity. The local entity processes the response message including using it to update its data cache to be consistent with the remote entity's data cache.

Abstract: The present invention pertains to an inkjet ink comprising performance additives and to an ink set comprising this ink, wherein the performance additives alleviate bleed in multicolor printed elements.

Abstract: A device for suspending and supporting various items including ice cubes or the like in common ice chests. The disclosed embodiments are comprised of an assembly of components including flexible fabric that is supported at its borders by a rigid frame or elastic frame, which is then attached to the ice chest with mounting components that are installed by the consumer or molded to the ice chest body during manufacturing. Items are placed on top of the fabric located at or near the top of the ice chest preventing the items from falling to the bottom of the ice chest where they may be damaged.
