Abstract: A traffic manager includes an execution unit that is responsive to instructions related to queuing of data in memory. The instructions may be provided by a network processor that is programmed to generate such instructions, depending on the data. Examples of such instructions include (1) writing of data units (of fixed size or variable size) without linking to a queue, (2) re-sequencing of the data units relative to one another without moving the data units in memory, and (3) linking the previously-written data units to a queue. The network processor and traffic manager may be implemented in a single chip.

Abstract: A waveguide couples an acoustic source (such as an ultrasound transducer) to a cosmetic product (such as a liquid or gel-based skin care product) applied to the skin. In one representative embodiment, a distal surface of the waveguide is placed in contact with a relatively thin layer of skin care product that has been applied to the skin. Alternatively, the thin layer can be applied to the distal face of the waveguide, and then the waveguide placed on the skin. The cosmetic product may be formulated such that when ultrasound energy is directed into the cosmetic product via the waveguide, microspheres in the cosmetic product oscillate and increase the permeability of the skin to active beneficial agents included in the cosmetic product.

In another implementation, a probe may have one or more inflatable bladders that form the HIFU therapy transducer. In yet another implementation, a probe may have an imaging component and a HIFU therapy transducer disposed thereon that rotate, as a unit, about a hinge.

An exemplary system may comprise a multiplexer, a table, and a scheduling circuit. The table may define when a port has access to the shared resource. The table entries may be based on the number of ports with access to the shared resource and the required bandwidth in each of the ports. The scheduling circuit controls the multiplexer according to the table, and the ports may gain access to the shared resource one port at a time.
