Abstract: Systems and methods for monitoring soiling of one or more photovoltaic (PV) modules. A sensor is provided that includes a measure chamber and a clean chamber. Cells in the measure chamber allow a measurement to be taken that accounts for soiling. Reference cells in the clean chamber can be exposed to incident light outside of the clean chamber. Measurements taken when the reference cells are outside of the clean chamber allow a clean output to be determined that is not subject to soiling. Comparing the output of the reference cell and the cells in the measure chamber allows a soiling loss to be determined.

Abstract: Described are systems, devices, and methods which related to various aspects of assays for detecting and/or determining a measure of the concentration of analyte molecules or particles in a sample fluid. In some cases, the systems employ an assay consumable comprising a plurality of assay sites. The systems, devices, and/or methods, in some cases, are automated. In some cases, the systems, devices, and/or methods relate to inserting a plurality of beads into assay sites, sealing assay sites, imaging assay sites, or the like.

Abstract: A resource management system of a computing resource service provider performs adoptions of virtual resource instances, such as virtual machine instances and virtual data store instances that were not instantiated as members of a logical container, into logical containers that are used to manage members of the logical containers as a group. Adopting such “candidate” resources that were not generated from programmable infrastructure templates allows the resources to be managed in accordance with an infrastructure-as-code framework, alongside resources that are generated from such templates. A template for launching infrastructure instances may be modified to include an adopted resource definition describing the configuration of the adopted resource, so that management operations can be performed on the adopted resource together with the other members of the container.

Abstract: An apparatus includes an ultrasonic transmitter, an ultrasonic receiver, and an acoustic delay gradient layer disposed in an acoustic path between the ultrasonic transmitter and the ultrasonic receiver. The acoustic delay gradient layer is configured to cause a reflection from a platen interface of the transmitted ultrasonic signal to reach the first receiver region at a first time and the reflection from the platen interface of the transmitted ultrasonic signal to reach the second receiver region at a second time that is different from the first time. The apparatus can further include a controller configured to set for a first region or portion of the receiver, a first range gate window (RGW). The controller is also configured to set, for a second region or portion of the receiver, a second RGW, and to establish a first temporal delay between the first RGW and the second RGW.

Abstract: An apparatus includes an ultrasonic sensor array and a sensor controller. The sensor array includes a plurality of ultrasonic sensor pixels, each sensor pixel including an ultrasonic receiver and a receiver bias electrode and being operable in one or both of a transmit mode of operation or a read mode of operation. The sensor controller is electrically coupled with the receiver bias electrodes. The sensor controller is configured to set, at each sensor pixel, a range gate window (RGW) by modulating a bias voltage applied to the receiver bias electrode and to set, for a first portion of the ultrasonic sensor pixels, a first RGW. The sensor controller is configured to set, for a second portion of the ultrasonic sensor pixels, a second RGW, and establish a first temporal delay between the first RGW and the second RGW.

Abstract: Headsets presented herein may include at least one earpiece having an adjustable bone conduction element and an ear bud. The location of the bone conduction element may be repositioned by sliding a slidably-coupled section to which the bone conduction element is attached. The ear bud may be disengaged without disturbing the positioning of the bone conduction element. Additionally, the earpiece may be attached to a base member via a pivoting element that is coupled to wire that retracts into the base member. The base member can be controlled by a cell phone and charge by plugging into a solar harness.

Abstract: The stent assembly with exterior banding for delivery of therapeutic agents of the present invention comprises a stent and drug coated bands located circumferentially around the stent. The width of the bands allows free flow of blood or other fluids to side branch lumens within the body. Positioning the bands on the abluminal surface prevents the intrusion of the bands into the inner diameter of the stent, thus optimizing patency. The therapeutic agent can vary from band to band, or different therapeutic agents can be included at different radial locations within the band. In an alternate embodiment, the stent assembly can comprise a stent and one or more helical wraps around the stent, the helical wraps including one or more therapeutic agent.
