摘要:
The scintillating screen of digital imaging systems used in conventional transmission electron microscopy is discretized and the scintillating material is contained in a cellular structure having a geometry judiciously selected for coupling to the optical channels of the imaging system. This allows optical matching, without smearing, between the elements of the scintillating screen and the discrete light-collecting and light-registering optical channels of the system. Cross-talk among optical channels is consequently minimized and the resulting light-imaging resolution of the digital imaging system is optimized.

A switch-type power converter comprising an FET switch operating in a variable duty cycle mode under the control of a Unitrode 3846 integrated circuit controller. Indications of excess input voltage and reverse battery connections are provided by circuits including an element which permanently changes state. A cooling fan mounted on a finned heat sink is operated in a variable speed mode. A single thermistor sensor provides inputs to both the fan speed control and a thermal shutdown circuit connected to shut down the gate drives to the FET switch in the event of a high temperature condition. Another shutdown function is provided in response to an input overvoltage condition by way of an operational amplifier. The converter uses foldback for short circuit protection and is compatible with microprocessor units to selectively provide multiple output voltage levels.

A combination tool for installing and crimping a cleat for fastening sections of ductwork, and for adjusting the threaded on support rods of strut channel for leveling the ductwork. The tool has an installing plate for holding a cleat and a removable handle that threads to the back of the installing plate. The handle has a hollow tubular body with a nut driver formed in the other end, for engaging and driving a threaded nut. The nut driver end is made by milling a rectangular slot transverse the axis of the hollow tubular body to form a pair of nut-engaging. A shank can be provided for attachment to the chuck of a power drill for rapid driving of the nuts. The tool also has a hinged crimping plate with threaded set screws for crimping the cleat securely to the flanges of the ductwork.

A security sensor system comprises one or more laser detection and ranging (LADAR) sensors configured for accumulation of three-dimensional image data. In one embodiment, the one or more LADAR sensors each comprise a LADAR device, such as a MEMS device, configured to transmit a plurality of laser pulses, and a microprocessor operatively coupled to the LADAR device. One or more data storage devices is operatively coupled to the microprocessor and configured to store the three-dimensional image data, as well as predetermined protected area boundary and fixed object definitions. A GPS receiver can be operatively coupled to the microprocessor and a GPS antenna. The microprocessor is configured to perform a LADAR image analysis that compares the three-dimensional image data with the protected area boundary and fixed object definitions to identify one or more potential intruders.

In preferred embodiments, the present invention provides methods of treatment and pharmaceutical compositions for the suppression, alleviation and prevention of the often chronic, severe and debilitating pain that can accompany inflammatory diseases and neuropathic insults, pain that is often unresponsive to conventional analgesic treatment. The preferred embodiments of the present invention further relate to methods of treatment and pharmaceutical compositions using benzodiazepine derivatives that provide suppression, alleviation and prevention of neuropathic pain, migraine-related pain and inflammatory pain with reduced sedative and ataxic side effects.
摘要:
A financial institution can provide financial services to a plurality of remote devices, such as personal computers, personal data assistants, screen phones, automatic teller machines, external service providers, and internally to staff terminals and individual branches. By separating the components of the system into independent components, the system and method can be developed and tested on a component level rather than the entire system level, thereby reducing the development and maintenance cycle time. The system and method operate in sessions and can employ a dialog component for gathering information from a customer, a rule broker component for providing answers to the various legal and regulatory rules in a particular country, a language man component for selecting appropriate language, a transaction executor component for performing transactions, and a presentation manager component for formatting outputs to the customer.

Improved SAW pressure sensors and manufacturing methods thereof. A SAW wafer including a number of SAW transducers disposed thereon may be provided. A cover wafer may also be provided, with a glass wall situated between the cover wafer and the SAW wafer. The cover wafer may be secured to the SAW wafer such that the glass wall surrounds the SAW transducers. In some instances, the glass wall may define, at least in part, a separation between the cover wafer and the SAW wafer. One or more contours may also be provided between the cover wafer and the SAW wafer such that at least one of the contours surrounds at least one of the SAW transducers when the cover wafer is disposed over and secured relative to the SAW wafer.

The present invention a method and apparatus for measuring the compression of a stator core 10 that comprises attaching a measuring device 22 to a tensioner 20, placing the tensioner on an end of a through-bolt 12 of the stator core, and performing at least one act of tensioning the stator core 10 with the tensioner. Then measuring a compression state of the stator core by the measuring device registers determining the amount of relative compression achieved by the act of tensioning, the relative compression is the amount of actual compression of the core and the amount of stretch of the through-bolt. Finally determining an actual compression state of the stator core based on the measuring.
