Abstract: Technologies are described for a distributed audio system configured to switch operating modes. In some examples, the distributed audio system may include a device configured to execute first instructions from a first memory corresponding to operation in a first mode, receive a signal to switch modes, and, responsive to receiving the signal, switch a select signal corresponding to the first memory to select a second memory. Responsive to selecting the second memory, the device may be configured to execute second instructions from the second memory corresponding to operation in a second mode. The device may enter a registration mode to register portable parts to the device.

Abstract: A material handling bucket apparatus including a material handling bucket and method of use thereof. The material handling bucket includes a bucket back half and a bucket front half. The bucket back half is configured to engage a loader. The bucket back half includes a plurality of guide slots and a dozer scraping lip configured to engage a surface. The bucket front half is pivotally coupled to the bucket back half. The bucket front half includes a plurality of slide members receivable in the plurality of guide slots. The plurality of slide members are configured to slide within the plurality of guide slots to allow the bucket front half to move linearly and pivotally relative to the bucket back half.

Abstract: Devices for intranasal administration of naloxone are disclosed. The devices comprise a foam applicator and are configured to locate an applicator comprising a naloxone composition, in proximity to the middle turbinate and/or inferior turbinate. Naloxone can be delivered to the nasal mucosa by squeezing the nostril against the applicator. The device and methods of using the devices can be used to treat an opioid overdose.

Abstract: Methods are provided for the synthesis of a compound of formula (X). R2 is selected from —H, —C1-C4-alkyl, —C2-C4-alkenyl and C1-C4-aryl; R3 is selected from —C(O)H and —C(O)C1-C4-alkyl; and A is a pharmaceutically acceptable anion (e.g. a halide). Also provided are intermediate compounds formed during the synthesis.

Abstract: A screed system includes a screed plate and a plurality of pressure sensors coupled to the screed plate and configured to sense a weight of the screed plate. A method for positioning screed system includes receiving pressure information from a plurality of pressure sensors engaged with a screed plate; determining a pressure distribution across the screed plate based on the pressure information; determining, based on the determined pressure distribution across the screed plate, an angle of attack of the screed plate; and adjusting the angle of attack of the screed plate.

Abstract: The screed plate apparatus and method has a road paver/finisher, screed plate, and material matting apparatus having a power source and structural/conductor plate. Paving material is loaded into the material matting apparatus and applied homogeneously as a paving mat to a road surface in a road paver/finisher travel direction. The structural/conductor plate is attached to the road paver/finisher and to the screed plate to provide indirect heat to the screed plate. The screed plate bottom side has differing forms of textured surface impacting the paving material, by differing corrugations of differing patterns, into a more homogeneous consistency. The corrugated pattern may be oriented parallel or perpendicular to the paver travel direction, and/or progressively flattening or set in a crisscross rhombic pattern. A vibrating and oscillating mechanism operates horizontally and vertically upon the screed plate providing a homogeneously sorting on the paving material.

Abstract: The modular screed plate assembly and method has a road paver/finisher, a structural/conductor plate and modular screed plates. The road paver/finisher has a paver under side, a power source and a heating element, for heating the modular screed plates. The modular screed plates have coupling elements, and retainer quick-connect/releases, and align as a modular screed plate array, providing a tensionally yielding gap allowing the modular screed plate array to absorb pressures from paving operations. The structural/conductor plate couples with the coupling elements and has screed plate retaining locks to securely receives the retainer quick-connect/releases, in order to secure itself to the modular screed plates. The structural/conductor plate receives heat directly from the heating element, and provides indirect heat to the modular screed plate array.
