Abstract: An autonomous solar collector cleaning device includes at least one main shaft, a first driver attached to a first end of the at least one main shaft, and a second driver attached to a second end of the at least one main shaft. The first and second drivers propel the cleaning device along a surface of the solar collector. A first sensor is attached to the first driver to detect an edge of the solar collector, and a second sensor is attached to the second driver to detect the edge of the solar collector. A control circuit maintains alignment of the cleaning device with respect to the solar collector based on outputs from the first and second sensors.

Abstract: Systems and methods capable of selecting and positively grasping objects of interest within a cluttered environment are described. Some aspects of the present disclosure provide for real-time control of a robot that uses various sensors and reacts to sensor input in real time to adjust the robots path. In some embodiments, a robotic item picker includes an end effector having a shaft extending along a longitudinal axis between a proximal end and a distal end, a carriage configured to rotate about and translate along an intermediate portion of the shaft between a proximal position and a distal position, a suction device coupled to the distal end of the shaft, and a plurality of fingers spaced radially about the carriage. The robot may be a t-bot including a longitudinal member rotatable about a lengthwise axis of the longitudinal member, a carriage translatable along the lengthwise axis, and a radial member slidably mounted to the carriage.

Abstract: A system or method for providing price transparency for healthcare or medical procedures or services and/or financing. Users are allowed to search by desired attributes (e.g., cost, procedure, location, etc.) to obtain pricing information for medical care. The system or method provides comparison of the costs of in-network and out-of-network medical services and cash-only payments. The user can choose medical care at a desired location, and schedule an appointment. Bundled packages of medical services and ancillary services can be offered to enable the user to compare bundled costs based on in-network and out of network medical services and cash-only payments. Any costs calculated by the system or method can account for copayments and deductibles and can enable a user to compare total out-of-pocket expenses with a cash-only payment option. Financing may be included. Advertisement revenue can be obtained on a click-through basis based on a healthcare provider profile.

Abstract: An apparatus and system for requisitioning medical procedures and/or corresponding devices or services. An apparatus system includes electronic devices or hardware, including processors and storage for containing digital data and transmitting communication signals among local hardware devices and/or remote (e.g., cloud-based) hardware devices in response to stimuli. The system may include particular data structures, variables and/or formats that are matched with stimuli during operation to control system output. Local and remote hardware components may be synchronized for redundancy purposes and/or speed during transactions.

Abstract: A system and method for cleaning a collector surface of a solar collector. The system includes a first liquid-dispensing unit configured to deliver a first spray of liquid to the collector surface. The system also includes a brush element having a longitudinal side oriented along a first direction and disposed adjacent to the first liquid-dispensing unit. A first squeegee element is oriented along the first direction and adjacent to the brush element. The first squeegee element, the brush element, and the first liquid-dispensing unit define a first cleaning area. A second squeegee element is oriented along the first direction and separated from the first squeegee element by a gap to define a second cleaning area. The system also includes a second liquid-dispensing unit configured to deliver a second spray of liquid to the second cleaning area located between the first and second squeegees.
