Abstract: A threat analyzer receives threat data measured by detectors. The threat data characterizes a status of detected emissions for a corresponding detector. The threat analyzer analyzes the threat data to identify a geographic region that contains a threat to humans and stores the threat data and analyzed data in a database. The machine readable instructions also include a graphical user interface (GUI) generator that provides an interactive map with indicia that characterizes the analyzed threat data.

Abstract: The apparatus is for use with a LAN that has a backup system, an Internet connection and an associated memory storage capacity. The apparatus comprises a computer case, data storage devices and a motherboard. The computer case is adapted to receive data storage devices at least equal in capacity to the LAN. The data storage devices are mounted in the case and have capacity at least equal to that of the LAN. The motherboard has an operating system, a virtualization product, a NAS program and a firewall. The firewall is operatively interposed between the LAN and the Internet connection to protect the LAN from attack. The NAS is configured to be active only during backup operations initiated by task manager components of the virtualization to facilitate a location for the backup of a mirror copy of the data on the LAN by the backup system on the data storage.

Abstract: The tool for expanding a bore swab is a device adaptable for uses such as cleaning, as an applicator or for polishing the inside of a bore or cavity. One embodiment of the tool allows the insertion of a swab, smaller than the bore, into a work piece and provides a means to increase the radial size of the swab as needed. This is accomplished in one embodiment by forming or placing a swab on the tool, which includes a rod with a head and a sleeve. When the sleeve is moved in an axial direction towards the head, the swab expands in radial size. Other embodiments are described and shown.

Abstract: Simulation of an electronic circuit including a model of a ferroelectric capacitor. The model of the ferroelectric capacitor includes a multi-domain ferroelectric capacitor, in which each of the domains is associated with a positive and a negative coercive voltage. A probability distribution function of positive and negative coercive voltages is defined, from which a weighting function of the distribution of domains having those coercive voltages is defined. The electrical behavior of the ferroelectric capacitor is evaluated by evaluating the polarization of each of the domains, as weighted by the weighting function. A time-dependent factor can be included in the polarization expression evaluated for each domain, to include the effect of relaxation. The effects of longer-term mechanisms, such as imprint, can be modeled by deriving a probability distribution function for the domains after an accelerated stress.

Abstract: A non-quasi-static model of the programming behavior of a floating-gate metal-oxide-semiconductor (MOS) transistor. This model is based on evaluation of a body current, for example determined as a function of voltages applied to the transistor from the circuit environment. The body current is used as an input to a non-quasi-static function on which the modeled gate injection current is based. In one example, the body current is applied to a representation of a series R-C circuit beginning from a time corresponding to the onset of avalanche breakdown, with the voltage across the capacitor serving as a control voltage of a voltage-controlled current source that drives the gate injection current. Integration of the gate injection current over the time interval of the programming pulse provides an estimate of the trapped charge at the floating gate.

Abstract: A system for consolidating multiple discrete machines and applications into a single rack mounted server system. Dedicated application servers maintain the discrete machines as virtual machines accessible by thin clients through secure hardwire or wireless connections and through client management servers. The system polls the application servers to compile lists of available and active applications. The list of available applications is displayed to users via an application navigation graphical user interface. The graphical user interface presents a menu from which users can point and click to select the application they wish to access.

Abstract: A wear-resistant cast iron rocker arm or similar machine element is formed by differential pressure, countergravity casting an iron melt of low superheat into a ceramic investment shell mold maintained initially at room temperature and rapidly solidifying the melt therein to provide a wear-resistant, as-cast microstructure throughout the body of the element. The as-cast microstructure comprises a dendritic constituent of austenite or transformed austenite (e.g., pearlite) depending on alloy composition and an interdendritic carbide constituent. Interdendritic ledeburite will also be present if the austenite remains untransformed. The as-cast microstructure of the rocker arm is devoid of graphite.
