A three-sided channel coupler for connecting the upper and lower portions of a U-shaped sign post, the coupler comprising two U-shaped elements, an outer three-sided, U-shaped element and an inner, three-sided U-shaped element, the three sides of each element comprising a transverse face and two lateral legs, the inner element being smaller than the outer element, a plurality of cross-braces attached to the two lateral legs of each element to hold the two elements together and a plurality of vertical ribs on the inner surface of the outer element and on the outer surface of the inner element.

Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

An exemplary suppressant actuator assembly includes a release member movable from a first position that restricts flow of a suppressant to a second position that permits flow of a suppressant. A biasing member moves from a more-biased position to a less-biased position to move the release member from the first position to the second position. A solenoid is activated to permit movement of the biasing member.

The present invention includes novel techniques, apparatus, and systems for optical WDM communications. Tunable lasers are employed to generate respective subcarrier frequencies which represent subchannels of an ITU channel to which client signals can be mapped. In one embodiment, subchannels are polarization interleaved to reduce crosstalk. In another embodiment, polarization multiplexing is used to increase the spectral density. Client circuits can be divided and combined with one another before being mapped, independent of one another, to individual subchannels within and across ITU channels. A crosspoint switch can be used to control the client to subchannel mapping, thereby enabling subchannel protection switching and hitless wavelength switching. Network architectures and subchannel transponders, muxponders and crossponders are disclosed, and techniques are employed (at the subchannel level/layer), to facilitate the desired optical routing, switching, concatenation and protection of the client circuits mapped to these subchannels across the nodes of a WDM network.

Devices, systems and methods are disclosed for repairing soft tissue. The surgical system allows for the creation of tissue repair by grasping, aligning and sewing or fixing tissue. For example, this system may be used for clipping together excessive capsular tissue and reducing the overall capsular volume. The deployment device includes a central grasping mechanism and an outer clip delivery system. The clip embodiments may be single or multi-component (penetration and locking base components) that penetrate tissue layers and deploy or lock to clip the tissue together. An example of the system is used to reduce the joint capsule tissue laxity and reduces the potential for subluxation or dislocation of the joint by either restricting inferior laxity (anterior or posterior) and resolving or eliminating pathologic anterior or posterior translation.

An automated budget management and bill payment system is provided where there is at least one customer (1), at least one bank (5), and multiple billers (3). The system has a customer registration process which requires the customer (1) to commit to make regular customer payment to the bank (5) for the cost of bills rendered to the customer (1) by the billers (3). This enables budgeted funds for bill payment to be provided. The customer (1) payment is based on a budget setting process (25) involving all of the anticipated bills from all of the billers (3) over a period of time. The customer (1) registration process also requires the customer (1) to identify each one of the billers (3). A billers (3) registration process is required where each of the billers (3) identifies a respective bill “pay into” account. The system requires the billers (3) to forward bill details to both the customer (1) and the bank (5) and wherein funds are drawn/transferred directly from the budgeted funds of the customer and there is payment of the drawn fund into the biller's “pay into” account for payment of a bill.
摘要:
A solid or screen bowl decanting-type centrifuge comprising:a rotatable bowl; a helical scroll conveyor which rotates coaxially within the bowl at a different rotational speed, the helical scroll comprising a hub carrying a plurality of flights whose radially outer edges lie close to an inner wall of the bowl such that, in use, solids are scrolled by the conveyer to solids discharge ports at one end of the bowl, with separated liquid being discharged from liquids discharge ports at the opposite end of the bowl. The conveyor hub carries a plurality of nozzles in a wash zone for supplying wash fluid to solids being scrolled by the conveyer towards the solids discharge ports. The conveyor hub also carries a blade in the region of the nozzles and intermediate adjacent flights of the conveyor for directing fluid droplets from the nozzles over said solids.

A system for analyzing one or more ion species of a sample including a first ion mobility filter associated with a first flow path for passing first ions of the sample, a second ion mobility filter associated with a second flow path for passing second ions of the sample, a first outlet from the first flow path for passing a portion of the first ions from the first flow path to the second flow path, and a first outlet from the second flow path for removing neutral particles from the second flow path where the first outlet from the second flow path is upstream of the second ion mobility filter in relation to the ion flow in the second flow path.
