摘要:
A circuitry (10) is provided for automatically retiming a received synchronous data signal to a local clock. The circuitry (10) includes a first flip-flop (20) operable to register at least one synchronous data signal in response to a receive clock signal and to generate at least one data output signal. An OR gate (26) receives a data latch enable signal and a local clock signal. The local clock signal is frequency coherent with the receive clock signal. The OR gate (26) produces an enable signal. A latch (28) is coupled to the OR gate (26) for receiving the enable signal and in cascading arrangement with the first flip-flop (20). The latch (28) latches the data output signal on the falling edge of the local clock signal when the data latch enable signal is low. The latch (28) holds the latched data output signal as long as the local clock signal and the data latch enable signal are low. When either the local clock signal or the data latch enable signal is high, the latch (28) passes the data output signal. A second flip-flop (30), coupled in cascading arrangement with the latch (28), registers the data output signal passed through the latch (28) in response to the local clock signal. The signal output by the second flip-flop (30) is timed to the local clock signal.

A vehicle ordering system that recommends to a vehicle dealership a vehicle to order from a vehicle manufacturer based on past sales (at various sales time periods and taking into account sales at the dealership level versus sales at the district and/or region level), current inventory (including in stock and in route), anticipated but not yet finalized orders, dealership size and calculated metrics derived from and using those elements.

A method for constructing a radio frequency filter (100) includes depositing on a dielectric substrate (102) a plurality of layers of a conductive material (210, 216, 218, 220, 222), a dielectric material (217), and a sacrificial material (1200, 1500, 1700, 1900). The deposition is controlled to form at least one transmission line (104, 106, 108) including a shield (202) and a center conductor (204) disposed coaxially within the shield. The deposition is further controlled to form at least one distributed filter element electrically coupled to the center conductor (204), and at least one housing (402) electrically coupled to the shield. The method also includes dissolving at least one layer of the sacrificial material to form an interior channel (226) within at least one shield. The dissolving of the sacrificial material also results in the formation of a interior space within at least one housing containing the distributed filter element.

Increasing the effective aperture of an ultrasound imaging probe by including more than one probe head and using the elements of all of the probes to render an image can greatly improve the lateral resolution of the generated image. In order to render an image, the relative positions of all of the elements must be known precisely. A calibration fixture is described in which the probe assembly to be calibrated is placed above a test block and transmits ultrasonic pulses through the test block to an ultrasonic sensor. As the ultrasonic pulses are transmitted though some or all of the elements in the probe to be tested, the differential transit times of arrival of the waveform are measured precisely. From these measurements the relative positions of the probe elements can be computed and the probe can be aligned.

A method has been described for making an electrical structure having an air dielectric and includes forming a first subunit including a sacrificial substrate, an electrically conductive layer including a first metal on the sacrificial substrate, and a sacrificial dielectric layer on the sacrificial substrate and the electrically conductive layer. The method further includes forming a second subunit including a dielectric layer and an electrically conductive layer thereon including the first metal, and coating a second metal onto the first metal of one or more of the first and second subunits. The method also includes aligning the first and second subunits together, heating and pressing the aligned first and second subunits to form an intermetallic compound of the first and second metals bonding adjacent metal portions together, and removing the sacrificial substrate and sacrificial dielectric layer to thereby form the electrical structure having the air dielectric.

A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate apertures of ultrasound arrays. Some embodiments provide systems and methods for designing, building and using ultrasound probes having continuous arrays of ultrasound transducers which may have a substantially continuous concave curved shape in two or three dimensions (i.e. concave relative to an object to be imaged). Other embodiments herein provide systems and methods for designing, building and using ultrasound imaging probes having other unique configurations, such as adjustable probes and probes with variable configurations.

A communication plate extends along and is sandwiched between cylindrical communication manifolds of a first heat exchanger assembly and a second heat exchanger assembly. The communication plate includes a saddling surface arcuate in one direction and a saddling surface arcuate in the opposite direction for engaging in saddle-like fashion the cylindrical shape of the manifolds. The communication plate defines a plurality of communication plate orifices disposed along the communication plate and aligned co-axial with a plurality of communication orifices disposed along the manifolds to seal the communication orifices of the manifolds and establish distributed and sealed fluid communication between the heat exchanger assemblies.

A lightning protection system, method and aircraft are provided for reducing the flammability of jet fuel spilled during an in-flight refueling operation between a supplying aircraft and a receiving aircraft. An inert gas is injected adjacent to a refueling interface in order to displace oxygen in the fuel-air mixture and thereby reduce the ability of the fuel vapor to ignite upon occurrence of an ignition source such as lightning. The refueling system may comprise a boom or a hose and drogue type device.
