Abstract: A method includes monitoring performance of a generated model while the generated model is being used for classification on live data, the monitoring including determining a first performance value of the generated model at a first point in time and determining a second performance value of the generated model at a second point in time; rendering, within a graphical user interface, a plot including a first axis and a second axis, the first axis including a characterization of a first performance metric and the second axis including a characterization of a second performance metric; and rendering, within the graphical user interface and the plot, a first graphical object at a first location characterizing the first performance value and a second graphical object at a second location characterizing the second performance value. Related apparatus, systems, techniques and articles are also described.

Abstract: Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

Abstract: Polymeric rings may be provided with an inner band formed of a polymeric material; and an outer band attached to the inner band and defining a channel about an inner circumference thereof, such that the inner band is uniformly disposed within the channel. In some embodiments, the outer band has a first outer diameter and a first inner diameter and defines a channel of a channel diameter, greater than the first inner diameter, in an inner surface of the outer band, the channel having a cross-sectional shape and a mating surface; and an inner band having a second outer diameter substantially equal to the channel diameter and a second inner diameter substantially equal to the first inner diameter, the inner band having the cross-sectional shape, the inner band being disposed in the channel and having a roughened outer surface attached to the mating surface of the channel.

Abstract: There is disclosed a compact wallet, comprising at least two rigid plates at least one having a channel into which an encircling elastic band is interposed to bias the at least two rigid plates inwardly and securely hold the card-like contents while providing elastic volume therebetween while allowing freedom for the dynamic extension and contraction of the band over the entire running length of the wallet. The wallet includes an auxiliary feature removably attached within the interior at least one of the at least two rigid plates interposed using a tang inserted into a recess formed inside the plate, the tang having a hook, the hook extending at an angle to the tang, the hook engaging an undercut of the recess to prevent inadvertent dislodgement of the auxiliary feature from the recess.

Abstract: A keycase includes a longitudinal top plate, a longitudinal bottom plate, a flexible connector connecting the longitudinal top plate and the longitudinal bottom plate, a key post coupled to the longitudinal bottom plate and extending from the longitudinal bottom plate toward the longitudinal top plate. The key post is configured to hold one or more keys. The key case further includes a fastener configured to detachably connect the key post and the longitudinal top plate and secure the key post with the longitudinal top plate, and a key pushing liner coupled to the longitudinal bottom plate and configured to push the one or more keys toward the longitudinal top plate.

Abstract: The present invention is a compact wallet designed to present a minimal silhouette in a shirt, pants or purse pocket. Novel features hold the silhouette to the minimal dimensions of a credit card while affording maximal expandability for content storage and accessibility. A novel method makes additional features modularly available.
