摘要： A permanent magnet is fabricated such that it has a magnetically hard core surrounded by a thin magnetically soft shell. The magnetically hard core provides a relatively high intrinsic coercivity (Hci), and the magnetically soft shell provides a relatively high magnetic flux density (B). Due to magnetic exchange coupling between the core and shell, a relatively high maximum energy product (BH)max is achievable over a wide temperature range, including temperatures above 150° C. Further, such effects can be achieved without using rare-earth metals or precious metals helping to keep the manufacturing costs of the magnet low. To allow sufficient exchange magnetic coupling between the core and shell, the width of the shell is less than about 40 nanometers, and the overall dimensions are controlled such that the width of the shell is less than two times the Bloch domain wall thickness of the core.

摘要： A hybrid dinghy pusher for pushing motorhomes is provided. A hybrid vehicle can be connected to a motorhome by a tow bar for towing the hybrid vehicle. When being towed behind a motorhome, the hybrid vehicle can be switched into hybrid dinghy pusher mode. In this mode, during acceleration of the motorhome, the electrical batteries and motors of the hybrid vehicle can provide a propulsive force through the tow bar to the motorhome, which assists the motorhome in accelerating and improves fuel efficiency. Additionally, the dinghy motors can act as generators when appropriate, creating energy which can be stored in batteries for later use during acceleration. The resistance created by the hybrid vehicle can also provide an additional braking force to the motorhome via the tow bar.

摘要： A smart object may be used to monitor the hydration level of a person. The object has at least two impedance sensors that can be used to sense the complex impedance of a person when a tissue of the user comes into contact with the impedance sensors. The measured impedance can then be used to determine the hydration level of the person. In addition to using the impedance sensors to determine the hydration level of the person, the impedance sensors can also be used to capture an electrocardiogram for the person. The smart object may also be used with another smart object to determine the identity of the user or other physiological parameters of the user such as blood pressure.

摘要： Systems and methods are provided to implement moving target defense techniques for transportation systems. The moving target defense techniques can randomly change the IP addresses of the nodes associated with both the vehicles and the corresponding control centers. The nodes for the vehicles and the control centers can be “mobile” nodes that use a “care-of” IP address for communications. The care-of address used by the nodes can be updated through a binding update process. During the binding update process, the one node sends the binding update notice (with a new care-of address) to the care-of address of the other node while maintaining its prior care-of address. The node that receives the binding update notice can send a binding acknowledgement back to the node that sent the binding update. Once the binding acknowledgement is received, the prior care-of address can be removed by the node that sent the binding update.

摘要： An antenna module (22) has an antenna (21) that is formed on a ferrite substrate (31), and the ferrite substrate is positioned within a small direct current (DC) magnetic field. The magnetic loss tangent of the ferrite is controlled by application of the small DC magnetic field, thereby improving antenna radiation efficiency and increasing the bandwidth of the antenna.

摘要： A silicon photomultiplier (SiPM) device is provided with a SiPM matrix and a temperature compensation circuit fabricated on a substrate. The temperature compensation circuit can include a temperature sensor, a bias adjustment circuit and a current source. The current source can provide a current to the temperature sensor and the temperature sensor can provide a temperature dependent signal to the bias adjustment circuit. The bias adjustment circuit can adjust a bias voltage provided to the SiPM matrix in response to the signal from the temperature sensor in order to maintain a predefined overvoltage value at the SiPM matrix.

摘要： An object redirection system may generate a high-resolution three-dimensional map of a surface of a target. Based on the map, the system may identify locations on the target's surface and direct energetic pulses toward the target at the locations. The system may continuously update the map of the target and continue emitting pulses at the target with reference to the map in order to achieve a desired velocity of the target within a desired timeframe.

摘要： A fiber optic directional sensor has a substantially hemispherical dome surface and a substantially flat surface. The sensor is formed from a plurality of optical fibers fused to one another, and each optical fiber extends from the dome surface to the flat surface. One end of each optical fiber is substantially perpendicular to the sensor's dome surface, and the opposite end of the fiber is substantially perpendicular to the sensor's flat surface such that an end face of the fiber is substantially tangent to the dome surface, and another end face of the fiber is substantially tangent to the flat surface. The sensor further includes an optical element which expands the field of view of the sensor and chromatically controls the incoming light. Using the sensor, light from projectiles, such as missiles, bullets, and other weaponry, can be detected, and the locations of the projectiles can be determined.
