Abstract: Sensory feedback (“chaperoning”) systems and methods for guiding users in virtual/augmented reality environments such as walk-around virtual reality environments are described. Exemplary implementations assist with preventing collisions with objects in the physical operating space in which the user acts, among other potential functions and/or uses.

Abstract: Systems and methods for implementing radial density masking graphics rendering for use in applications such as head mounted displays (“HMDs”) are described. Exemplary algorithms are disclosed, according to which image resolution varies within an image depending on the distance of a particular point on the image from one or more fixation points. Reconstruction algorithms according to certain embodiments include three stages: (1) hole filling; (2) cross-cell blending; and (3) Gaussian blur.

Abstract: Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes a combined piston pump and rotatable valve. The piston pump is configured to prevent partial dosing of a bolus dose.

Abstract: Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes an inlet check valve, a first outlet check valve downstream of the inlet check valve, and a piston pump disposed between the inlet check valve and the first outlet check valve. The piston pump is configured to prevent partial dosing of a bolus dose.

Abstract: Apparatuses, methods, and systems are described herein for automating toolface control of a drilling rig. Such apparatuses, methods, and systems may change operating parameters of the drilling rig responsive to detected toolface orientations. Thus, if a toolface orientation of the drilling tool is determined to be outside an advisory sector, updated operating parameters may be determined and provided to the drilling tool. The updated operating parameters may change at least one of a clockwise rotation target or counterclockwise rotation target of the drilling tool.

Abstract: Apparatuses, methods, and systems are described herein for automating toolface control of a drilling rig. Such apparatuses, methods, and systems may determine an average drilling resistance function during a rotary drilling segment and, based on the average drilling resistance function during the rotary drilling segment, determine a target set of oscillation values to be used during a slide drilling segment.

Abstract: A method includes receiving and storing, at a server, retail product data related to a retail product offered for sale at a retailer, the retail product data including text data corresponding to a description of the retail product, price data corresponding to a price of the retail product, and image data corresponding to a graphical image of the retail product. The method also includes receiving, at the server, links to content generated by a content-generating user, the content being associated with retail products. The method also includes identifying, at the server, a link from the plurality of links that corresponds to content associated with the retail product offered for sale at the retailer. The method also includes generating, at the server, a web page that displays the product data, including the text data, the price data, and the image data for the retail product offered for sale at the retailer and that displays the identified link.

Abstract: A method includes receiving and storing, at a server, a project listing associated with a project that includes at least one shopping-related activity and providing access to the project listing to users. The method also includes receiving, at the server, a request for participation in the project from a user and receiving, at the server, approval for an approved user to participate in the project, based on the request. The method also includes receiving, at the server, a link to content generated by the approved user, the content being associated with the approved user's performance of the at least one shopping-related activity and the content including at least one of text content, image content, and video content. The method also includes providing, at the server, access to the link to the users.

Abstract: A latch includes three circuits. The first circuit drives a first output (QB) to a first level when a first input (D) and a first clock phase (CK) are both low, to a second level when D and CK are both high, and provides high impedance (HI-Z) when different logic levels are applied to D and CK. The second circuit drives a second output (Q) to the first level when a third input (DB) and a complimentary clock phase (CKB) are both low, to the second level when DB and CKB are both high, and provides HI-Z when different logic levels are applied to DB and CKB. The third circuit maintains voltages of Q and QB when the first and second circuits provide HI-Z at Q and QB. Odd-number dividers constructed with such latches produce 50% duty cycle operation without restricting output pulse widths to integer multiples of input periods.
