Some embodiments provide a method for providing a layer 2 (L2) bump-in-the-wire service at a gateway device (e.g., a layer 3 (L3) gateway device) at the edge of a logical network. The method, in some embodiments, establishes a connection from a first interface of the gateway device to a service node that provides the L2 service. The method also establishes a connection from a second interface of the gateway device to the L2 service node. The method then sends data messages received by the gateway device that require the L2 service to the service node using the first interface. Some embodiments provide a method for applying different policies at the service node for different tenants of a datacenter. Data messages received for a particular tenant that require the L2 service are encapsulated or marked as belonging to the tenant before being sent to the service node. Based on the encapsulation or marking, the service node provides the service according to policies defined for the tenant.

Some embodiments provide a method for detecting a failure of a layer 2 (L2) bump-in-the-wire service at a device. In some embodiments, the device sends heartbeat signals to a second device connected to L2 service nodes in order to detect failure of the L2 service (e.g., a failure of all the service nodes). In some embodiments, the heartbeat signals are unidirectional heartbeat signals (e.g., a unidirectional bidirectional-forwarding-detection (BFD) session) sent from each device to the other. The heartbeat signals, in some embodiments, use a broadcast MAC address in order to reach the current active L2 service node in the case of a failover (i.e., an active service node failing and a standby service node becoming the new active service node). The unidirectional heartbeat signals are also used, in some embodiments, to decrease the time between a failover and data messages being forwarded to the new active service node.

An inkjet printing fluid composition including water and a water dispersible polyurethane additive of the general formula of (I)wherein Z is the central portion of a monomer unit that is the polymerization product of a diisocyanate; X1—Y1—X1 represents one or more soft segments wherein Y1 represents the central portion of a unit that is the polymerization product of a diamine or diol prepolymer having a molecular weight of greater than 300 Daltons; W is the central portion of one or more units containing an acid group; X2—Y2—X2 represents one or more hard segments wherein Y2 represents the central portion of a unit that is the polymerization product of a C2-C8 diol or diamine having a molecular weight of less than 250 Daltons; and X1, V and X2 can be the same or different and are an —O— or —N— atom; and further wherein the polyurethane additive has a weight average molecular weight of at least 6,000 Daltons and a sufficient number of acid groups to provide an acid number greater than 35, and the one or more X2—Y2—X2 hard segments are present at from 1 wt % to less than 13 wt % of the polyurethane additive. Also disclosed is a method for printing an inkjet image including I) providing an inkjet printing fluid according to the invention; and II) jetting the inkjet printing fluid in the form of ink drops onto a recording element to form a printed image.

The present invention is directed to the creation of optical waveguiding devices from standard optical fibers by the creation of zones of permanently altered refractive index characteristics therein. A high intensity femtosecond laser beam is focused at a predetermined target region in the fiber so as to soften the glass material at the target region. After aligning the focal region with the target region in the fiber there will be relative movement between the focal region and the fiber, which has the effect of sweeping the focal region across the fiber in a predetermined path. The result is a zone within the fiber in which the refractive index characteristics of the fiber have been permanently altered so as to control amplitude, phase, spatial propagation or polarization states of light within the material.

The present invention provides a method of providing a monetary incentive to a health care provider, typically a physician, responsible for treatment decisions of a patient with a condition during an episode of care. Once the patient identity and condition are obtained, a baseline value related to treatment of the condition can be associated. Thereafter, all the claims processed during the episode of care of the patient for the condition can be summed to obtain a total treatment cost. If the total treatment is less than the baseline value, then a monetary incentive can be provided to the provider based upon that episode of care. The healthcare provider may be a member of a managed care organization, such as an accountable care organization, and the monetary incentive may be modified based on time interval for the episode of care.

In an imaging method and a tomosynthesis apparatus, a two-dimensional low-energy image of the predetermined volume segment is obtained after administration of a contrast agent, followed by a two-dimensional high-energy image and then a high-energy tomosynthesis of the predetermined volume segment is obtained with a high total radiation dose that is significantly higher than the low radiation dose. The two-dimensional low-energy image is subtracted from the two-dimensional high-energy image to generate a result with which the concentration of the contrast agent is visible. Additionally, in a time interval in which an enrichment or a washing-out of the contrast agent occurs within the predetermined volume segment, a tomosynthesis of the predetermined volume segment is automatically implemented to show the concentration of the contrast agent in the predetermined volume segment.

A laser-working method is disclosed, which includes the steps of splitting a single pulse laser beam having a time width of not more than 500 picoseconds into plural pulse laser beams; subjecting said plural pulse laser beams to time delaying, and adjusting a working surface-irradiating shape, an intensity distribution and a working surface-irradiating position of each of the plural pulse laser beams; working a target object to be irradiated, while the respective working surface-irradiating shapes of said plural laser beams are partially or entirely spatially overlapped with each other or one another; and setting to a time interval of from a pulse width to 1 nanosecond a time period during which each of the pulse laser beams is irradiated.
