Abstract: A wellhead monitoring system includes a conversion assembly, the conversion assembly including an actuator element for modifying an operating mode of a valve from manual to remote. The system also includes one or more sensors, associated at least one of a fracturing tree or the conversion assembly, the one or more sensors obtaining wellhead operating conditions. The system further includes a control unit, adapted to receive information from the one or more sensors, the control unit presenting the information, on a display, and transmitting the information to a remote system for analysis.

Abstract: Auto-detecting an action on a merchant service and rendering an offer button to display an offer redeemable based on the action. A user accesses a merchant service and an indication of the action is communicated to an offer system that maintains an account for the user. The offer system determines whether the user has an offer applicable to a purchase with the merchant. The user device presents an offer button rendered to indicate that the first offer is available for redemption by the user. The user initiates an action on the merchant service and the user device communicates an indication of the action to the offer system. The offer system determines if the user has a second offer applicable to a purchase with the merchant based on the action taken by the user and the offer button is rendered to indicate that the second offer is available for redemption.

Abstract: A drill string rotation angle sensor diagnostic system includes a first rotation angle sensor assembly, a second rotation angle sensor assembly, an operator interface; and a control module. The control module is configured to receive a first signal from the first rotation angle sensor assembly, receive a second signal from the second rotation angle sensor assembly, determine if a valid state exists based on the first signal and the second signal, and indicate a fault on the operator interface if a valid state does not exist.

Abstract: The present disclosure relates to field of an arrangement of multiple optical elements to generate multiple beam patterns. The arrangement (100) of multiple optical elements to plurality of fasteners (112), and an optics plate (106). The array board (102) having LEDs (104) mounted thereon in a plurality of first blade patterns (124a-124d). The optics plate (106) is removably fastened to the array board. The optics plate (106) defines lenses (108) in a plurality of second blade patterns (126a-126d) and reflectors (110) in a plurality of third blade patterns (128a-128d), identical to the first blade pattern (124a-124d). The optics plate (106) is manually rotated into a first configuration to align the second blade pattern (126a-126d) with the first blade pattern (124a-124d) and into a second configuration to align the third blade pattern (128a-128d) with the first blade pattern (124a-124d) to generate multiple beam patterns.

Abstract: A child-resistant dispenser includes a housing (110); and a slider (150) disposed on the housing and configured to slide from a closed position to a dispensing position, the slider comprising a movable engagement portion (148) that engages a stop (122) on the housing, wherein the engagement between the movable engagement portion and the stop restricts movement of the slider to the dispensing position and the movable engagement portion is configured to disengage from the stop in response to a release force applied to the slider.

Abstract: The present invention provides a sound attenuation system that includes a base having a first portion on an emitter end of the base and a second portion on a receiver end of the base, wherein the first portion has a first longitudinal axis, wherein the second portion has a second longitudinal axis, and wherein the first longitudinal axis is at a first angle to the second longitudinal axis; an adapter having a first end and a second end; a sound-attenuation plug, wherein the first end of the adapter is configured to couple to the sound-attenuation plug, and wherein the second end of the adapter is configured to couple to the first portion of the base; and a receiver-end component configured to insert into the second portion of the base.

Abstract: A Pancharatnam Berry Phase (PBP) color corrected structure is presented that comprises a plurality of switchable gratings and a plurality of PBP active elements. Each switchable grating has an inactive mode when reflects light of a specific color channel, of a set of color channels, and transmits light of other color channels in the set of color channels, wherein the specific color channel is different for each of the plurality of switchable gratings, and to have an active mode to transmit light that is inclusive of the set of color channels. The PBP active elements receive light output from at least one of the plurality of switchable gratings. Each of the PBP active elements is configured to adjust light of a different color channel of the set of color channels by a same amount to output light corrected for chromatic aberration for the set of color channels.

Abstract: A boat, having a transom, includes one or more aft-facing seats. Each aft-facing seat is positioned proximate to the transom and includes a seat bottom that is inclined at a downward angle in a direction extending from aft to fore, a seatback, a headrest, a seat support structure having at least one hidden compartment therein, and at least one pivot mechanism attached to the seatback and the headrest and configured to allow the seatback to move between a first position in which the seatback is capable of supporting the back of a person seated in the seat and a second position in which the seatback is pivoted upwardly to allow access to the compartment and the headrest to move between an upright position and a folded position. A plurality of handles may be provided for each aft-facing seat, with one at an outboard side and another at an inboard side.
