Abstract: One aspect of this disclosure is a climbing skin attachment apparatus. The apparatus may comprise a climbing skin attachment portion and a snow device connection portion, a channel extending at least partially through the climbing skin attachment portion along a channel axis to receive an anchor portion of a climbing skin, and a passage extending through the climbing skin attachment portion and into the channel along the channel axis to receive a lead portion of the climbing skin. Related apparatus, methods, and systems also are described.

Abstract: A X-bit Digital-to-Analog Converter (DAC) circuit includes an effective X/2-bit coarse DAC configured to produce a coarse bitstream (CBS) from a digital input DC1 using an nth order Sigma-Delta (??) modulator, and to provide a coarse current source based on the CBS, wherein X is an even integer and n is an integer; an effective X/2-bit fine DAC configured to produce a fine bitstream (FBS) from a digital input DC2 using a 1st order ?? modulator, and to provide a fine current source based on the FBS; and an output configured to form a voltage from the combination of the coarse current source and the fine current source.

Abstract: There is described herein methods and devices for high DC gain closed loop operation amplifiers exploiting cascaded low gain stages and a controller-based compensation circuit for stability.

Abstract: A system and method for enabling users to draw emojis for insertion into electronic text-based messages are disclosed. The system receives a handwritten drawing input from a user composing an electronic text based message on a computing device. The handwritten drawing input is to represent an emoji for insertion into the message, and comprises a series of strokes input to the computing device by the user. The system analyzes the series of strokes and matches the analyzed series of strokes to at least one emoji in a set of emojis. The user can then select the at least one emoji for insertion into the message.

Abstract: A method and system for an aircraft communications system. The aircraft communications system comprises an Internet protocol network router and an aircraft communications addressing and reporting system network router. The Internet protocol network router, located within an aircraft, is configured to transmit data to a group of ground stations remote to the aircraft using an Internet protocol communications link. The aircraft communications addressing and reporting system network router, located within the aircraft, is connected to the Internet protocol network router. The aircraft communications addressing and reporting system network router is configured to transmit the data from aircraft systems to the group of ground stations using at least one of an aircraft communications addressing and reporting system communications link or, via the Internet protocol network router, using at least one of an Internet protocol communications link.

Abstract: A system, method, and computer-readable storage medium for enabling an individual to use a purchase-proxy mechanism to conduct a financial transaction from a computing device with an online merchant, whereby the individual is enabled to use stored personal data, such as financial account information and fulfillment information, without having to store the personal data with the online merchant. The system, method, and computer-readable storage medium furthermore enable an individual to change a payment and/or fulfillment option at the time of purchase with minimal inconvenience.

Abstract: Climbing aids for use on snow comprising a climbing skin and one or both of a climbing skin tip and tail are disclosed. At least the climbing skin tip and/or tail is comprised of a flexible sheet that may be composed of a plastic polymer. Embodiments are disclosed in which the sheet is resilient and curved in a generally transverse direction to transfer forces towards the edges of the climbing aid to reduce entry of snow between the climbing aid and the undersurface of a ski or snowboard.

Abstract: A trailer (50, 60) has a chassis (1) which is fabricated from sheet plastics material. The chassis (1) is hollow and substantially planar and has an upper sheet (6) and lower sheet (10) separated by a peripheral wall (12). The shape of the chassis is generally dart like being formed by a forward triangle 3 and a rear rectangle (4). The sheet plastics material is preferably high density polyethylene which is 16 mm thick.

Abstract: Systems for analyte detection are disclosed. The system includes absorption channels positioned along a surface of an object. The absorption channels are configured to trap an analyte. The system further includes a sensor embedded in the object and configured to detect the presence of the analyte. The sensor includes a light source configured to transmit light and a detector configured to detect a change in an intensity of light transmitted by the light source. The sensor further includes a cable configured to connect the light source to the detector, wherein the cable comprises detection regions, and wherein the detection regions include a portion of the cable exposed to the analyte in the absorption channel.
