Abstract: Various devices for providing foot controlled computing device inputs are discussed herein. Some embodiments may include a rolling foot controller including a housing, one or more motion sensors disposed within the housing, and processing circuitry. The housing may include an upper portion configured to interface with one or more feet, and a lower portion configured to facilitate motion of the rolling foot controller when disposed on a ground surface. The processing circuitry may be configured to receive the motion data generated by the one or more motion sensors, and provide the motion data to a computing device, especially with regards to rotation in the pitch, yaw, and roll directions. The upper portion is generally of convex shape, curved about one or more axes, and the lower portion is generally convex as well, curved about two or more axes.

Abstract: A light-emitting system is provided which is removably attachable to headgear for personal illumination to enhance visibility of the user to others. The light-emitting system includes a housing that defines a receiving aperture and is configured to surround a portion of the headgear when the light-emitting system is removably attached to the headgear for use. The light-emitting system further includes at least one lens and a plurality of lighting elements coupled to the annular housing which are configured to selectively generate a halo or at least a partial halo of light that radiates outwardly away from the annular housing through the at least one lens to provide enhanced personal illumination.

Abstract: Systems and methods of providing composite search results are disclosed. A search query may be received by a general purpose search engine of a first website from a user. At least one general purpose search result may be determined based on the search query using the general purpose search engine. The at least one general purpose search result may be based on a search of multiple websites. Item listing information of an item listed for sale on a second website may be determined based on the search query. The at least one general purpose search result and the item listing information may be caused to be displayed concurrently on the first website to the user. The user may be enabled to interact with the second website regarding the item by interacting with the item listing information displayed on the first website.

Abstract: A system and method of metadata refinement using behavioral patterns is disclosed. In some embodiments, user behavioral data for results of a search query is received. The results can include an untagged item and a plurality of tagged items. A determination can then be made that the tagged items have been assigned a plurality of types of metadata. The untagged item can then be identified as a candidate to be tagged with at least one of the plurality of types of metadata assigned to the tagged items. In some embodiments, the user behavioral data comprises clickstream data indicating that a user selected the untagged item and at least one of the tagged items during a single search event.

Abstract: Methods and systems to build containers of uncategorized items are described. In some example embodiments, the methods and systems collect information from titles of items available for purchase within a network-based publication system, generate a title for a container of uncategorized items available for purchase within the network-based publication system that is based on the collected information, and associate two or more uncategorized items available for purchase within the network-based publication system to the container based on a comparison of titles of the two or more uncategorized items and the generated title for the container of uncategorized items.

Abstract: A piston may be provided which includes a first piston body portion having an end wall extending radially about a central axis along which the piston reciprocates. The piston may also include a second piston body portion having an end wall extending radially about a central axis along which the piston reciprocates. The first piston body portion and the second piston body portion are axially opposed. The piston may further include a first piston rod bore disposed in the first piston body portion extending along the central axis and a second piston rod bore disposed in the second piston body portion extending along the central axis. The piston may also include a circumferential opening disposed between the mating of the first piston body portion with the second piston body portion.

Abstract: Systems and methods of providing composite search results are disclosed. A system may receive input via a user interface of a device accessing a first website, and determine item listing information of an item listed for sale on a second website based on the received input, with the second website being different from the first website. The system may cause the item listing information to be displayed on the first website on the device via the user interface, and enable the device to interact with the second website, via the user interface, regarding the item listed for sale by interacting with the item listing information being displayed on the first website.

Abstract: A system and method allows the operation of a remotely located tool in an application where there is a telescoping space out joint in such a manner that the hanger need not be released. A hydraulic piston is surface actuated to move gripping teeth against the pipe and then take the pipe with the gripping teeth so that a tool that is engaged by the string can be remotely operated while safety features for the well can remain operative. The shifted position is held with maintained control line pressure. Some release of the control line pressure will not allow the operating piston to return. Rather, a check valve holds the shifted piston position until a differential pressure on the check valve drops to a predetermined value so that the check valve acts as a dump valve. The system operates off annulus pressure if the control line is damaged.

Abstract: Methods, computer-storage media, and graphical user interfaces are provided for identifying and presenting rich related sites for task-oriented search queries. Upon receipt of a search query input by a user, one or more query logs are analyzed to determine if the search query is a related to a task being performed by the user. If the query is determined to be a task-oriented search query, search results are identified, as is one or more Uniform Resource Locators (URLs) related to a particular search result. The related URL is presented to the user in association with the particular search result. Additional controls, e.g., search tools that facilitate querying of those URLs determined to be relevant to a particular search result, may also be provided to aid the user in performing the task at hand.
