Abstract: A group of glass compositions in the Li2O—Al2O3—SiO2—B2O3 family that can be chemically strengthened in single or multiple ion exchange baths containing at least one of NaNO3 and KNO3 for a short time (2-4 hours) to develop a deep depth of layer (DOL). In some instances, the DOL is at least 70 ?m; in others, at least about 100 ?m. The ion exchanged glasses have a high damage resistance (indentation fracture toughness ranging form greater than 10 kgf to greater than 50 kgf) that is better than or at least comparable to that of sodium aluminosilicate glasses.

Abstract: Ion exchangeable glasses containing SiO2, Al2O3, Na2O, MgO, B2O3, and P2O5 are provided. The compressive stresses of these ion exchanged glasses are greater than 900 megapascals (MPa) at a depth of 45 or 50 microns (?m) with some glasses exhibiting a compressive stress of at least 1 gigaPascals (GPa). The ion exchange rates of these glasses are much faster than those of other alkali aluminosilicate glasses and the ion exchanged glass is resistant damage to impact damage. A method of ion exchanging the glass is also provided.

Abstract: The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 ?m to 50 ?m), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

Abstract: The present systems, devices, and methods relate to managing shared vehicle access. Authorization policies are stored at a network device, and are provided to vehicle devices. Authorization policies each include an authentication scheme, a list of permitted vehicle operations, and a list of requirements to perform vehicle operations. In this way, whether even if a user is authenticated to access a vehicle, vehicle access is controlled based one whether the user is permitted to perform vehicle operations, and whether requirements are met to perform vehicle operations. This provides a flexible and roust vehicle access system. Authorization Policies are distributed to vehicle device in an Access Configuration, which can be updated.

Abstract: An embodiment provides a method for measuring an amount of total organic fluoride content of a PFAS containing sample, including: placing a sample comprising a PFAS compound in a measurement device, wherein the measurement device comprises an oxidation cell and a non-oxidation cell, wherein the oxidation cell comprises a boron-doped diamond electrode; measuring, using the measurement device, an amount of total inorganic fluoride of the sample before an oxidation; applying an electrical potential to a portion of the sample in the oxidation cell, wherein the electrical potential oxidizes the PFAS compound; measuring, using the measurement device, an amount of total organic fluoride of the sample after the oxidation to provide a measurement signal of the total organic fluoride; and determining a first derivative of the measurement signal of the total organic fluoride. Other aspects are described and claimed.

Abstract: A micro-transfer structure comprises a stamp comprising a rigid support, only a single contiguous bulk layer disposed on the rigid support, and posts disposed on the bulk layer. Components are adhered to (e.g., disposed in contact with) some but not all of the posts. The posts can be substantially identical and disposed in a regular array on the bulk layer. Each component is adhered to (e.g., in contact with) two or more posts. Components can be disposed on a source wafer entirely over sacrificial portions of a sacrificial layer on or in the source wafer and attached to anchors disposed between sacrificial portions with a tether.

Abstract: An electronic device may be provided with a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.

Abstract: A device for retaining a supra pubic catheter having a moveable retainer axially moveable along the catheter.

Abstract: A retention element has an axial portion having an internal conduit adapted to receive and engage a catheter. The retention element further includes a radially extending flange portion having an annular sidewall extending outwardly from the axial portion to an outer perimeter. The radially extending flange portion is adapted to contact the patient and secure the catheter, thereby retaining an inflatable balloon of the catheter in a position to seal the stomal tunnel. The radially extending flange portion is preferably generally conical in shape, such that only the outer perimeter of the radially extending flange portion contacts the patient at a contact location that is a distance from the stomal tunnel, and the annular sidewall does not contact the patient adjacent the stomal tunnel.

Abstract: A manual large game carrying device of the type having a substantially elongated upper receiving bar (30) that accommodates and secures large game at points of securement (32). The manual large game carrying device can be turned by a handlebar configuration (22) which engages a front fork axle assembly (20) at the frame/front fork/handlebar junction (44). This front fork axle assembly (20) is connected to the front rotatable wheel (10A) by the releasable front axle (12). In addition, the manual large game carrying device's speed is controlled by braking mechanism levers (26). The braking mechanism levers (26) engage the braking mechanism linkages (28), which engage the braking mechanisms (42) attached to the front brake rotor (16) and rear brake rotor (18). In addition to steering and stopping the manual large game carrying device, the handlebar configuration (22) has handle grips (24) conveniently placed for efficient transport.
