摘要:
A method, system and computer program product for avoiding unnecessary grace period token processing while detecting a grace period without atomic instructions in a read-copy update subsystem or other processing environment that requires deferring removal of a shared data element until pre-existing references to the data element are removed. Detection of the grace period includes establishing a token to be circulated between processing entities sharing access to the data element. A grace period elapses whenever the token makes a round trip through the processing entities. A distributed indicator associated with each processing entity indicates whether there is a need to perform removal processing on any shared data element. The distributed indicator is processed at each processing entity before the latter engages in token processing. Token processing is performed only when warranted by the distributed indicator. In this way, unnecessary token processing can be avoided when the distributed indicator does not warrant such processing.

A method, apparatus and program storage device for performing a return/rollback process for RCU-protected data structures is provided that includes checking a user-level state of a preempted thread having a RCU read-side critical section, and executing the critical section of the thread after preemption when the user-level state of the thread indicates execution, otherwise returning to a point of preemption, resuming execution of the thread and disabling checking the user-level state when the user-level state of the thread indicates return.

A method and apparatus for enhancing communication services in an evolved global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) are disclosed. At least one full rate physical channel and/or half rate physical channel are provided to support communication services that do not require higher order modulation (HOM), and at least one fractional rate physical channel is provided to support the communication services that require HOM. The fractional rate channel occupies N timeslots for every M frames of a channel, whereby N/M is less than one half. The fractional rate channel may be used when communication services are provided on a channel that uses either 16 or 32 quadrature amplitude modulation (QAM) in a dual transfer mode (DTM) session. The communications services include at least one of voice communication services, circuit switched (CS) services and supplementary services.

In one embodiment, a method can include: (i) receiving a contact center interaction request via a device coupled to a display screen; (ii) accessing information about the device or a user of the device from a customer database of a content provider; and (iii) establishing an interaction path between the contact center and a viewer. The method can further include providing information to the user via the interaction path in response to a request by the user for the information. The device can be a set-top box (STB) or a cable card and the display screen can be a television, for example. Also, the content provider can be a cable or satellite television provider, for example.

A system for moving a pallet is provided. The system provides for a pair of pallets each having means for inducing movement in relation to an other pallet. Further, logic is provided for calculating a movement instruction to move the pallets relative to each other. Additionally, the present invention provides for means for communicating the movement instruction to the movement means on the pallets to prompt movement of one of said pair of pallets relative to the other pallet. As no special floor surface or configuration is necessary, the present invention described herein may be readily adaptable for utilization within existing storage and inventory facilities.

A packaging system for transporting vials containing biological samples may comprise a first tray defining at least one first tray cavity; and a second tray defining at least one second tray cavity and configured to mate with the first tray. The packaging system may further comprise at least one first tray cavity and at least one second tray cavity, wherein the at least one first tray cavity and the at least one second tray cavity are configured to securely hold respective vials for transport, and to restrain caps on the respective vials during transport, wherein the at least one first tray cavity and the at least one second tray cavity oppose each other when the first tray and the second tray are mated together. The packaging system may also be configured to permit barcode scanning of vials held within the first tray cavity and the second tray cavity.
