Abstract: An agricultural harvester includes an auger assembly including an auger having an auger shaft defining an axis of rotation and a fighting carried by the auger shaft, the auger being configured to rotate the fighting in a sweeping path about the axis of rotation and convey cleaned crop material toward the crop material elevator; an auger trough placed adjacent to the auger to hold crop material in the sweeping path; and an auger cover held above the sweeping path that is configured to direct flung crop material toward the auger and/or the auger trough.

Abstract: In one embodiment, a method includes accessing one or more content objects associated with a first user of an online social network; generating a set of tag candidates by extracting one or more n-grams from the content objects, wherein each tag candidate comprises one or more text strings or ideograms from the extracted n-grams; calculating, for each tag candidate of the set of tag candidates, a quality-score for the tag candidate based on an affinity coefficient between the first user and a respective content object from which the n-grams or ideograms comprising the tag candidate were extracted; and sending, to a client system for display, one or more of the tag candidates as suggested tags for the first user, wherein each suggested tag has a quality-score greater than a threshold quality-score.

Abstract: Provided herein are systems and methods for an active sensing instrument actively utilizing the Christiansen effect to sense and adapt to suspended scatterers such as dust. The instrument enhances detection of remote surfaces that are partially or fully obscured at visual wavelengths due to those suspended scatterers. The system also may be used to measure properties and spatial distributions of the suspended scatterers themselves. Though the system is broadly applicable to remote detection through scattering media, it is particularly drawn to remote sensing through dust particles in the atmosphere as may be produced from helicopter fly-overs, dust storms, or other events that draw up substantial concentrations of mineral-based dust particles into the air.

The tool includes an attachment member having opposed ends, one of these opposed ends is configured to grip a cemented or non-cemented intramedullary implant stem in a bone. The attachment member has a size and shape to be received into the hole and the other of opposed end includes at least one hook feature for gripping the implant. The tool includes an elongated lever having an elongate proximal section and a shorter distal end section with a pivot fulcrum at a transition from the distal end section to the elongate proximal section.

Abstract: A bilateral upper limb exercise device (10) for exercising a user's arms comprising a central mounting structure (12) that is mountable to a fixed surface or structure (15), left and right limb supports (14a, 14b) for supporting the forearm and/or hand of a respective arm of the user, and a pair of articulated linkage arms (22a, 22b) that are pivotably coupled to opposite sides of the central mounting structure (12) and which are arranged to support a respective limb support (14a, 14b) for movement in at least two degrees of freedom in a two-dimensional (2D) movement plane. A mirroring mechanism is also operatively coupled to the articulated linkage arms (22a, 22b) such that movement of the opposing limb support relative to a central line of symmetry of the device.

Abstract: The present invention includes a bucket anchoring device that limits or prevents a bucket from rotating when mixing thick, heavy, or low-viscosity materials within it. The anchoring device includes a ring having a plurality of removable, flexible engagement members extending from an inner circumference of the ring. The bucket is placed in the ring such that the engagement members contact and frictionally engage an outer surface of the bucket, similar to a sprag. The user steps on footpads located on the top of the ring to provide an anchoring force to the ring and therefore the bucket, thereby preventing rotation.

Abstract: Combining fulfillment of customer orders from merchants in computer-facilitated marketplaces. An order management system may include a virtual shopping cart interface that may be used with a number of merchants. Each merchant may be registered to receive fulfillment services from a fulfillment services provider for inventory items the merchant offers in commerce. The virtual shopping cart interface may be configured to receive requests to indicate various items within a virtual shopping cart corresponding to a customer. Different inventory items offered by different merchants may be placed within the virtual shopping cart. In response to the customer's request to finalize an order, the order management system may instruct the fulfillment services provider to ship the items in the virtual shopping cart to the customer. A single shipment may include items offered by several different merchants, and each of the merchants may be the merchant of record for its respective inventory item.

Abstract: A facility for managing ownership of units of an item is described. The facility defines a commingling zone. For units of the item that are outside the commingling zone, the facility attributes ownership among a plurality of owners individually to each of the units. For units of the item that are inside the commingling zone, the facility attributes ownership among the plurality of owners to particular numbers of the units without attributing ownership individually to each of the units. The facility includes a method for reconciling ownership of units in the event of any discovered innacuracies.

Abstract: Each LDIF entry of a directory tree is read, split to a domain of LDIF fragments (corresponding to backend servers) and written to each LDIF fragment. The split may be accomplished through a hash function, establishing, for that iteration of LDIF entry, a write file. The LDIF entry is appended to the write file. A subsequent LDIF entry is read. A corresponding LDIF fragment is determined, which need not be different from the LDIF fragment to which the first LDIF entry was written. The current LDIF entry is written to the currently selected write file. The process continues until all LDIF entries are exhausted from the directory tree. LDIF fragments are each copied to distinct backend servers, where, each LDIF fragment may be loaded into a distributed directory data structure.

Abstract: Method and apparatus for providing inventory fulfillment services to customers who have small quantities of heterogeneous items to sell. A self-service registration interface for generating lists of items to sell via the inventory fulfillment service is provided. The inventory fulfillment service may provide pricing suggestions to the customer. The inventory fulfillment service may determine whether a listed item satisfies one or more listing rules. Shipping information for a list of items may be automatically generated and provided to the customer. The customer may ship the items in one shipment to a specified facility. The customer is the seller of record for all items listed. The customer may not be charged for services until an item is sold. A listing period may be specified for which listed items will be carried. If an item does not sell within the period, option(s) for disposal of the item may be provided.

Abstract: A process and communication equipment is provided for secured e-mail using security associations between mail domains of the Internet. E-mail passes though at least one device having a list of security associations. The sending domain equipment verifies the name of the destination domain of each e-mail received from its mail server based on a list of existing security associations. If there is no security association, the e-mail receives an identifier and is transferred to the receiver. If there is no identical communication equipment at the receiver, the e-mail is transferred in transparent state. If there is identical communication equipment at the receiver side, the e-mail is verified by the receiving equipment for an identifier and transferred to the receiver. If there is an entry in the security association list, the e-mail is transmitted in a secured state using the security parameters of the destination domain.
