Exception event recorders and analysis systems include: vehicle mounted sensors arranged as a vehicle event recorder to capture both discrete and non-discrete data; a discretization facility; a database; and an analysis server all coupled together as a computer network. Motor vehicles with video cameras and onboard diagnostic systems capture data when the vehicle is involved in a crash or other anomaly (an ‘event’). In station where interpretation of non-discrete data is rendered, i.e. a discretization facility, captured data is used as a basis for production of supplemental discrete data to further characterize the event. Such interpreted data is joined to captured data and inserted into a database in a structure which is searchable and which supports logical or mathematical analysis by automated machines. A coupled analysis server is arranged to test stored data for prescribed conditions and upon finding such, to initiate further actions appropriate for the detected condition.

We disclose a compact source for high brightness x-ray generation. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sources, or through the use of novel x-ray targets that comprise a number of microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and / or higher energy electrons, leading to greater x-ray brightness.The orientation of the microstructures allows the use of an on-axis collection angle, allowing the accumulation of x-rays from several microstructures to be aligned to appear to have a single origin, also known as “zero-angle” x-ray emission.

This disclosure presents systems for x-ray illumination that have an x-ray brightness several orders of magnitude greater than existing x-ray technologies. These may therefore useful for applications such as trace element detection or for micro-focus fluorescence analysis. The higher brightness is achieved in part by using designs for x-ray targets that comprise a number of microstructures of one or more selected x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray flux. The high brightness / high flux x-ray source may then be coupled to an x-ray optical system, which can collect and focus the high flux x-rays to spots that can be as small as one micron, leading to high flux density.

A compact source for high brightness x-ray generation is disclosed. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sub-sources, or through the use of x-ray targets that comprise microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and / or higher energy electrons, leading to greater x-ray brightness.Some embodiments of the invention comprise x-ray optical elements placed between sub-sources of x-rays. These x-ray optical elements may form images of one or more x-ray sub-sources in alignment with other x-ray sub-sources, and may enhance the linear accumulation that can be achieved.

A heat dissipation module for removing heat from a heat-generating electronic component includes a base (106) and a clip (40, 40a). The clip includes a connecting arm (42, 42a) and a securing arm (44, 44a) for locking the base to the heat-generating electronic component. The connecting arm engages with the base. The securing arm extends from the contacting arm and is curve-shaped with a free end thereof being for being depressed whereby the securing arm exerts a downward force on the base so that the base and the electronic component can have an intimate contact with each other.

A Micro Blade is described for implementing an electronic assembly having a thin profile; it is a miniaturized stand-alone unit that is mechanically and thermally rugged, and connects to external components using a cable. The electronic assembly is preferably fabricated on a copper foil substrate including an interconnection circuit, a special assembly layer, and directly attached components. The components are preferably in bare die form, and are preferably attached using plated copper spring elements inserted into wells filled with solder. The copper foil substrate may be folded to form a compact system in package (SIP) inside of the Micro Blade. A jacket comprised of thermally conductive members is formed around the electronic assembly using hermetic seams. The Micro Blade is preferably cooled by immersion in water contained in a tank; the water is cooled and circulated using an external pumping system.

We present a micro-x-ray fluorescence (XRF) system having a high-brightness x-ray illumination system with high x-ray flux and high flux density. The higher brightness is achieved in part by using x-ray target designs that comprise a number of microstructures of x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray flux. The high brightness / high flux x-ray source may then be coupled to an x-ray optical system, which can collect and focus the high flux x-rays to spots that can be as small as one micron, leading to high flux density at the fluorescent sample. Such systems may be useful for a variety of applications, including mineralogy, trace element detection, structure and composition analysis, metrology, as well as forensic science and diagnostic systems.

A computer system includes a chassis and an airflow guiding duct. The chassis includes a chassis bottom wall, a chassis front wall and a chassis rear wall. The chassis front wall defines a first ventilation hole, and the chassis rear wall defines a second ventilation hole. A motherboard is secured to the chassis bottom wall between the chassis front wall and the chassis rear wall. A memory card is secured to the motherboard. The airflow guiding duct is secured in the chassis and includes an entrance portion. The entrance portion covers a portion of the memory card, so as to guide airflow. Airflow flows in the chassis via the first ventilation hole, over the memory card, and then out of the chassis via the second ventilation hole.

An electronic system includes a case, a plurality of fans, a plurality of shafts, at least one leaf member, and a plurality of elastic elements. The case defines a plurality of exits. The fans are fixed in the case corresponding to the exits. The shafts are fixed in the case corresponding to the fans. The at least one leaf member is rotationally mounted to one of the shafts. The elastic elements are mounted to one of the shafts to bias the at least one leaf member to close the corresponding exit. A guide apparatus for the electronic system is provided as well.

Disclosed are targets for generating x-rays using electron beams and their method of fabrication. They comprise a number of microstructures fabricated from an x-ray target material arranged in close thermal contact with a substrate such that the heat is more efficiently drawn out of the x-ray target material. This allows irradiation of the x-ray generating substance with higher electron density or higher energy electrons, leading to greater x-ray brightness, without inducing damage or melting. The microstructures may comprise conventional x-ray target materials (such as tungsten) that are patterned at micron-scale dimensions on a thermally conducting substrate, such as diamond. The microstructures may have any number of geometric shapes to best generate x-rays of high brightness and efficiently disperse heat. In some embodiments, the target comprising microstructures may be incorporated into a rotating anode geometry, to enhance x-ray generation in such systems.
