摘要： A compact, reliable scanning electron-beam x-ray source achieves reduced complexity and cost. In particular, the x-ray source includes an electron beam that is propagated parallel to an x-ray target and is swept across the target in response to a moving magnetic cross field. Rather than scanning the beam by deflecting it about a single point, the point of deflection is translated along the target length, dramatically reducing the volume of the device. The magnetic cross field is translated along the target length using either mechanical systems to move permanent magnets, or electrical systems to energize an array of electromagnets.

摘要： An electron beam amplification device provides trajectory modulation of an electron beam, and includes an electron gun, a modulator, an interceptor, an output circuit, and a collector. The electron gun produces an electron beam. The modulator receives an RF input signal and provides a corresponding electromagnetic field region that alters trajectory of the electron beam in correspondence with the RF input signal. The interceptor has at least one aperture oriented such that the electron beam transmits through the aperture when the electron beam altered by the modulator follows a particular transmission path and impacts upon the interceptor when the electron beam trajectory altered by the modulator follows a path other than the particular transmission path. The output circuit is arranged so that the electron beam transmitted through the interceptor aperture passes therethrough and produces an RF output signal. The collector recovers remaining energy of the electron beam after passing through the output circuit. An optional post-accelerator may be located between the modulator and the output circuit for increasing energy of the electron beam exiting the interceptor aperture.

摘要： A low power self-organizing network is made up of a plurality of wireless communication nodes communicating wirelessly with each other. The nodes each have a sensor providing a respective sensor data value indicative of a physical parameter in the environment of that node. The wireless network discontinues communication with any nodes in which the sensor data value is outside a range of network sensor data values. The network is preferably a group of vehicles moving ' together, especially a train in which each node is associated with a respective wheel of a railroad car. The nodes are low-power devices that communicate using wireless communications according to a Zigbee protocol. The nodes each have an additional sensor sensing a physical parameter the respective wheel thereof and determines from said electrical signal a degree of degradation of a bearing of the wheel, and transmits data of the degree of degradation to the main node. The main node communicates with another computer system using a higher power communication system and transmits thereto data indicative of degradation of said bearings.

摘要： A distributed simulation system is composed of simulator stations linked over a network that each renders real-time video imagery for its user from scene data stored in its data storage. The simulation stations are each connected with a physics farm that manages the virtual objects in the shared virtual environment based on their physical attribute data using physics engines, including an engine at each simulation station. The physics engines of the physics farm are assigned virtual objects so as to reduce the effects of latency, to ensure fair fight requirements of the system, and, where the simulation is of a vehicle, to accurately model the ownship of the user at the station. A synchronizer system is also provided that allows for action of simulated entities relying on localized closed loop controls to cause the entities to meet specific goal points at specified system time points.

摘要： Disclosed is an electronics packaging systems, which provides for a high density assembly of groups (2a, 2b, 2c, 2d) of similar solid state part packages. The system provides a novel method which includes the use of interconnect members (5) and crossover members (8) for interconnecting the signal paths, structurally assembling and supporting the parts (2a, 2b, 2c, 2d), and removing heat generated within the components (1). The system approach disclosed typically starts at the level of assembling pre-packaged parts (2a, 2b, 2c, 2d) into modules, and permeates through to the printed circuit board (6, 9) and box levels of assembly. The system is applicable, but not limited to, solid state memory device packaging, which typically consists of many similar parts interconnected in a matrix bus type configuration. The assembly of a building block of numerous memory components allows for the modular construction of large amounts of solid state memory.

摘要： A method is disclosed for obtaining a spreading code set for a Code Division Multiple Access (CDMA) communication system. The method includes generating of P' xP' as well as P' xP spreading code where P' = P/N, wherein P is the spreading gain in chips/symbol and where N is an integer multiple of 2 as shown Figure 8. The method also teaches how to calculate the bandwidth of the signal after being multiplied by the spreading codes in both vector and matrix form.

摘要： Digital video signals are transmitted from a transmitter to a receiver (100B) via a digital video interface including shielded twisted pair cables (200A, 200B) that are surrounded by an over-braid shield (250). The over-braid shield is connected to a chassis ground (140) at a transmitting end and the receiving end. An interface conveys the received signals to receiver processing circuitry (150). The interface is connected to an isolated ground (125B), isolating the receiver processing circuitry. Cable shields of the twisted pairs are also connected to the isolated ground (125B), such that a return current is forced back through the twisted pair cable shields rather than the over-braid shield. This reduces electromagnetic emissions and confines transients primarily to the over-braid shield.
