Abstract: An authentication system authenticates remotely generated optical control signals. A remote optical emitter transmits an optical control signal from a remote location. A remote authentication device collocated with the remote optical emitter receives an authentication challenge signal and transmits a compatible authentication response signal. A control optical signal processor positioned at a first location receives the optical control signal from the remote optical emitter and generates a control output signal in response to detection of a valid optical control signal. An authentication device is coupled by a real time data communications link with the optical signal processor and with the remote optical emitter.

Abstract: A method for providing decision support through visualization of participant past performance is performed using a computer system associated with an electronic marketplace. The method includes retrieving stored past performance information for participants reflecting the performance of the participants in connection with prior transactions conducted using the marketplace. Substantially linear viewable objects are generated for display to a user, each object corresponding to a participant and including one or more subdivisions, each defined by first and second subdivision boundaries. Each subdivision corresponds to a past performance measure and has a length that is proportional to a value of the measure determined according to the past performance information for the participant corresponding to the object.

Abstract: In one embodiment, a method is provided for planning repairs in response to demand in a multi-level repair network of locations at which parts may be repaired. Modeled for a location are: (1) an unserviceable buffer for parts inspected at the location and repairable at the location, and (2) a serviceable buffer for parts inspected at the location and serviceable without repair. A forecasted demand, for a quantity of serviceable parts at a future time at the location, is accessed. In a push planning phase, for each inspected part in the unserviceable buffer, the earliest time at which repair can begin for the part at the location is estimated.

Specific implementations feature a while-in-use electrical device cover that includes a base having an aperture configured to receive the face of an electrical device, a lid configured to close over the base through a hinge while an electrical connector is inserted into the electrical device, and a cord port extending through a surface of the cover. The base and lid are substantially elliptical. The base, lid, and hinge may be manufactured from plastics or other conventional material for a while-in-use electrical device cover using conventional fabrication methods.

Abstract: A method for deploying parts is disclosed. Locations that include supply locations and demand locations are defined. A supply location supplies parts to a demand location. A demand is computed for each part at each location. An availability lead-time is estimated for each part at each location. A lead-time demand is computed for each part at each location using the availability lead-times for the part. A stock level is computed for each part at each location. A completely filled demand is determined from the lead-time demands and the stock levels, and a partially filled demand is determined from the lead-time demands and the stock levels. A coverage function for the parts at the locations is generated from the completely filled demand and the partially filled demand.

Abstract: A global content directory (42) includes a directory structure (44) that includes a plurality of product classes organized in a hierarchy. Each product class categorizes a plurality of products and defines one or more attributes of the products categorized in the product class. The directory (42) also includes one or more pointers that are associated with each product class. Each pointer identifies a seller database (32) in which product data enabling a product transaction is stored for products that are associated with the product class. The directory (42) also includes a search interface (45) that communicates, in response to a selection of a product class by a user (20) of the global content directory (42), a search query for product data to one or more seller databases (32) identified by the one or more pointers associated with the selected product class.

Abstract: A system for demand breakout for a supply chain includes a memory operable to store a plurality of orders for at least one product. Each product may be produced using at least one precursor. The memory is also operable to store a production schedule identifying one or more resources in the supply chain, a quantity of each product and precursor scheduled to be produced by the resources, and a time period associated with production of each product and precursor. The system also includes one or more processors collectively operable to identify one or more particular units of the product that correspond to each product order. The one or more processors are also collectively operable to identify one or more particular units of one or more precursors that correspond to each product order.

Abstract: Redistributing parts includes defining locations. An actual inventory of parts is established among the locations, and a desired allocation of the parts is established among the locations. A demand for the parts at each location is determined using the actual inventory and the desired allocation. Paths are determined, where a path transfers an excess part from one location to another location. A transfer function describing a cost of transferring the excess part along the paths is generated. The transfer function is optimized to achieve the desired allocation of the excess parts at a minimum cost.

Abstract: A recessed incrementally rotating nozzle assembly is located in a wall or bottom surface of a swimming pool in fluid communication through a conduit with a source of water under pressure from a valve, which valve periodically releases water into the conduit. Each time water flows, a nozzle housing is raised to eject a stream of water. As the nozzle housing rises, it is incrementally rotated by a pin engaging a saw tooth member of a cam ring. Upon cessation of flow, the nozzle housing is retracted and during retraction the nozzle housing is further incrementally rotated by the pin engaging another saw tooth member of the cam ring. After a predetermined degree of angular rotation, a cam reverser slidably reorients protrusions guiding the pin into and out of the saw tooth members to cause the pin to be guided by the opposite side of the saw tooth members and thereby cause reversal of the direction of rotation of the nozzle housing.

Abstract: A process for modeling at least a portion of a workflow includes accessing a computer data structure to represent an acyclic directed graph (10) including multiple nodes (12) and one or more edges (14), each edge (14) linking two adjacent nodes (12). The value of a function at a selected node (12) is requested, the value of the function at the selected node (12) depending on values of the function at one or more adjacent nodes (12) lying in a first direction from the selected node (12). If a cached value of the function at the selected node (12) is not assured to be valid, then the value of the function at the selected node (12) is recomputed based on the values of the function at the one or more adjacent nodes (12) and then returned. If the cached value is assured to be valid, then the cached value is returned without recomputing the value of the function at the selected node (12).

Abstract: A method for distributed inventory management includes receiving information regarding a number of participants in a value chain and information regarding one or more items relevant in the value chain. The method also includes modeling relationships between two or more of the participants based on the received information and modeling the one or more items based on the received information. Furthermore, the method includes receiving inventory data from the participants relating to the one or more items, processing the inventory data based on the models of the relationships and the items to generate inventory information related to one or more of the participants, and communicating the generated inventory information to one or more of the participants. The inventory information at least partially includes information regarding inventory data of participants other than those participants to which the inventory information is communicated.
