摘要： A system and method enabling precise range estimation and time synchronization between a first object such as a vehicle having a primary communications mechanism and an interconnected first controller, and a second object having a secondary communications mechanism and an interconnected second controller. The primary sends communications into the environment and the secondary receives them; the secondary then sends replies to the primary. The communications have information for determining range between the two objects and for comparing the second object's internal clock with a more accurate clock of the first object. Repeated exchanges of communications between the two objects enables additional precision of range as well as time synchronization information.

摘要： A device and method of use for the calibration of a detector. The calibration device includes a first source configured to produce first electromagnetic energy EMR. A first diffuser is connected to the first source and is configured to accept the first EMR and provide a first diffused portion of the first EMR. An integrating sphere defines an interior and is optically connected to the first diffuser, and is configured to accept the first diffused portion from the first diffuser into the interior. An exit port connected to the integrating sphere is configured to pass at least a portion of electromagnetic energy. A thermal mechanism is configured to adjust and maintain the temperature of at least the first source. The integrating sphere is configured to pass only a second portion of the first diffused portion of the first EMR from the first diffuser to the exit port. In another embodiment, the calibration device has an arm, an actuator, and a module. The module supports at least a first source that emits electromagnetic energy, a thermal mechanism, and a controller. The actuator is configured to move the arm and module to a calibration position enabling the first source to be within the line of sight of an external detector, while the controller is configured to control the thermal mechanism enabling precise temperature regulation of the source and therefore the regulation of the emitted electromagnetic energy. When the device is not in the calibration position, the actuator is configured to move the arm and module to a stowed position, protecting the device from ambient electromagnetic radiation and harm.

摘要： An efficient, large dynamic range electric motor system and method of operating same, including a frame, at least a first rotor-stator pair, together having a first dynamic range, and a second rotor-stator pair, having a second dynamic range, with the first and second pairs mounted within the frame for rotation about a common central axis of an output shaft, mounted for rotation about the first axis and configured to transfer torque from the first and second pairs. A clutch is configured to isolate at least one of the first and second pairs away from the output shaft, thereby establishing an at least one isolated pair, and preventing torque transfer between the at least one isolated pair and the output shaft. A controller is connected to the first and second pairs and is configured to control power delivery to the first and second pairs.

摘要： An ocean iron fertilization (OIF) method and system for electrochemically controlled release of iron in an ocean to stimulate growth of phytoplankton to increase CO2 sequestration by the ocean. The system includes a cathode submerged or floating in the ocean; an iron or iron-producing anode submerged or floating in the ocean spaced apart from the cathode; and a power supply unit connected to the cathode and the anode. The power supply unit drives electric current between the cathode and the anode such the anode generates oxygen (O2) and ferrous iron through electrolysis to be released in the ocean, and the cathode produces hydrogen (H2) and hydroxide (OH—) species through an electrochemical reaction at the cathode.

摘要： A system for the differentiation of plastic and non-plastic particles in suspension in a liquid, and the method of use thereof. The system having a channel for constraining and presenting the liquid to a detector, the detector having at least one transmit electrode for emitting electrical current to at least one receive electrode. Circuitry provides the current input and received electrical signals measurement capacities. Particles passing the receive electrodes alter the received electrical current according to the particle's dielectric properties, the circuitry records the received signals and discerns a particle's nature, most often plastic from non-plastic, from the differential signal of these received signals as a function of frequency.

摘要： A stowable generator device including a housing defining at least one storage chamber having an opening. A closure element is configured to selectively cover and uncover the opening. Support structure is disposed within the storage chamber in a collapsed position and is selectively extendable through the opening into an expanded position when the closure element is moved away from the opening. At least one energy generating unit is connected to the support structure. The support structure and the generating unit are configured to reversibly stow inside the housing in the collapsed position.

摘要： A system and method for detecting electrical events, often a corona associated with an impending lightning strike, including a coupling mechanism configured to establish an electromagnetic connection with a conductive substrate to receive signals intercepted by the conductive substrate. A detector circuit converts and discriminates the received signals into output signals. An output mechanism records and/or transmits the output signals, as well as determines if the output signal represents a qualified event signal.
