The number of managed network elements within a SONET network is configured to exceed the number addressable elements in a given address area. This is achieved through the use of SONET extension network elements and a special TL1 command message protocol. Any network element that has only one optical path (protected or unprotected) to an adjacent network in the SONET network can become an extension network element. TL1 command messages may be targeted to an extension network element through its only adjacent network element based on the network element's physical port connecting the network element to the extension network element.

The disclosed embodiments of exercise garments includes a torso portion adapted to substantially cover the torso of a user and one or more flaps. Each flap is secured substantially to a side of the torso portion. The exercise garment also includes at least one fastener adapted to selectively secure the pair of flaps across at least a portion of an abdominal region of the user. The fasteners may include a hook-and-loop arrangement (such as Velcro7), buttons or snaps. The illustrated embodiment includes a pair of flaps, which may overlap over the abdominal region when both flaps are secured. The fasteners may be adapted to provide adjustable positioning of the flaps. The adjustable positioning includes variable placement of the flaps relative to the abdominal region. The torso portion may also include a corset arrangement extending from a top portion of the torso portion downward through at least a portion of the abdominal region.

A reaction vessel used in industrial applications is heated by a multiple mode microwave beam that is directed to an interior wall of the reaction vessel. The beam is in an inclined-angular fashion and the wall is arranged so the beam is absorbed and reflected from it many times to provide a helical-like reflection and absorption pattern within the vessel interior to uniformly heat the vessel wall and the material. A microwave isolator connected between a source of the microwave energy and the reaction vessel includes a quartz plate and a seal for compensating disparities in thermal expansion coefficients between the plate and a housing for the plate.

A lockable quick-release mechanism for preventing theft of a bicycle wheel or seat from a bicycle frame. The lockable quick-release mechanism includes a rotatable lever having an eccentric cam rotating within a piston head. As the eccentric cam rotates within the casing, the piston head moves in relation to the casing. For tightening, the piston head is brought from its outermost to innermost position relative to its casing. Conversely, for loosening, the piston head is brought from its innermost to outermost position relative to its casing. Flat abutment surfaces are formed on the lever adjacent to the eccentric cam. A locking disc is disposed within the casing and includes a pair of extension arms engaging the abutment surfaces to prevent rotation of the lever. A spindle, which is disposed within the casing and extends through an aperture in the locking disc, rotates the locking disc from a locked to an unlocked condition. The spindle and locking disc are retained in the locked condition by a lock means.

The disclosed subject matter describes systems and methods of delivering a therapeutic agent, such as a sclerosing agent, to the walls of a blood vessel to perform sclerotherapy. In an exemplary embodiment a catheter includes a guidewire catheter having at least one guidewire lumen extending therethrough and a slidable concentric tube disposed over the guidewire catheter. At least one bellow is coupled to the concentric tube and configured for conversion between an unexpanded and expanded configuration wherein movement of the concentric tube in a first direction causes the at least one bellow to expand and movement of the concentric tube in a second direction causes the at least one bellow to contract. Additionally, the concentric tube contains at least one port for delivery of a therapeutic agent, e.g. a sclerosing agent. The at least one bellow expands and contracts via mechanical forces.

Methods and systems are provided for detection of unauthorized entities in communication systems. The method includes obtaining a secret string by a first network element and generating a random number by the first network element. The method also includes computing a first cryptographic result by the first network element. The first cryptographic result is based on a cryptographic function, the secret string, and the random number. The method further includes attempting to transmit, by the first network element, a first packet that includes the random number to a second network element using a layer 2 packet terminating protocol. The method includes receiving, within a configured time, a second packet including a second cryptographic result at the first network element, and terminating transmission to the second network element when a second cryptographic result is different from the first cryptographic result.

The invention is directed to in vitro methods of inducing differentiation of anterior foregut endoderm and the enriched populations of anterior foregut endoderm produced by such methods. Such enriched populations are useful for studies of the molecular events that occur during differentiation and for generating cells for cell replacement therapy.

A graphics engine with shader unit thread serializing and instance unrolling functionality that executes multi-threaded shader logic in a single hardware thread is described. Hardware accelerated tessellation functionality is implemented utilizing programmable pipeline stages that allow custom, runtime configuration of graphics hardware utilizing programs compiled from a high level shader language that are executed using one or more shader execution cores. In one embodiment, multiple shader unit program threads are serialized to run in one hardware thread to allow a greater number of instructions to be executed on the shader cores and preserve hardware threads for primitive processing by other shader units.

A modular device includes a first printed circuit board and a wireless transceiver (e.g., a radio). Electrical connectors (e.g., pads) are located along multiple edges of the first printed circuit board. The electrical connectors are in locations that correspond to a land pattern on a second printed circuit board. Along one edge of the first printed circuit board, the electrical connectors also correspond to electrical connections in a socket. For certification testing, for example, the device can be plugged into a socket. For installation in a host device, the device can be soldered down to the second printed circuit board.
