Abstract: Satellites having autonomously deployable solar arrays are disclosed. A disclosed example satellite includes a solar array, a sensor to detect that the satellite has exited a launch vehicle, a processor to, based on the satellite exiting the launch vehicle, enable release of magnets or locks of an array, a release controller to control the release of the magnets or the locks of the array based on a release sequence to autonomously deploy the solar array, and a sequence analyzer to adapt the release sequence during execution of the release sequence, wherein adapting the release sequence includes changing an order in which the magnets or the locks of the array are released based on a degree to which the solar array is unfolded.

Abstract: A device includes a cue generator for a vehicle. Like many vehicles, the vehicle has a windshield and a hood, a gas pedal and a brake pedal. The cue generator includes a light projector configured to project a distinct visual cue based on a type of engagement signal received. The cue generator is configured to receive a gas pedal engagement signal when the gas pedal is engaged, and a brake pedal engagement signal when the brake pedal is engaged. The device is configured to project the visual cue within a portion of the driver's peripheral field of view that corresponds to the hood of the car.

Abstract: An ultrasonic imaging agent is produced by a continuous sonication processing of an aqueous solution of heat-denaturable biocompatible protein. The solution is carefully preheated to a temperature of incipient protein denaturation without forming insolubilized protein. A gaseous fluid, preferably air, is added to the solution. In the sonication, the air-containing solution is foamed, increasing the formation and concentration of microbubbles, and the solution is further heated to insolubilize a portion of the protein, thereby encapsulating the microbubbles and forming particulate microspheres.
