Abstract:
A catheter-based system for performing a cryoablation procedure uses a precooler to lower the temperature of a fluid refrigerant to a sub-cool temperature (−40° C.) at a working pressure (400 psi). The sub-cooled fluid is then introduced into a supply line of the catheter. Upon outflow of the primary fluid from the supply line, and into a tip section of the catheter, the fluid refrigerant boils at an outflow pressure of approximately one atmosphere, at a temperature of about −88° C. In operation, the working pressure is computer controlled to obtain an appropriate outflow pressure for the coldest possible temperature in the tip section.
Abstract:
Methods, systems, and media to enhance image processing for a color reprographic system are disclosed. Embodiments of the invention may calibrate a component like scanner and/or printer in response to user input and/or coupling the component to the reprographic system. More specifically, embodiments may generate correction parameters that describe differences in color values between an image scanned by a scanner or an image printed by the printer by comparing the outputs to known characteristics like color values for the image. Some embodiments comprise a graphical user interface (GUI) to communicate with the user, allowing the user to select user preferences to change, for example, the brightness of an image being copied. Further embodiments incorporate network and phone system interfaces to communicate with remote components as well as to receive input from and/or output to other systems via email, facsimile, etc.

Methods, systems, and media to calibrate a reprographic system are disclosed. Embodiments of the invention may calibrate a component like scanner and/or printer in response to user input and/or coupling the component to the reprographic system. More specifically, embodiments may generate a curve that describes tone differences between an image scanned by a scanner or an image printed by the printer by comparing the outputs to acceptable tone descriptions for the image. Some embodiments comprise a graphical user interface (GUI) to communicate with the user, allowing the user to select user preference curves to change, for example, the brightness of an image being copied. Some embodiments incorporate network and phone system interfaces to communicate with remote components as well as to receive input from and/or output to other systems via email, facsimile, etc.
Abstract:
A multiple beam printer system having N laser beams receives print job information from a print host. A rendering application uses a threshold array to generate halftone image data from the print job. The threshold array is defined based on a spot function. The defined screen is non-orthogonal and includes Y pels in a direction that is perpendicular to a scanning direction of the laser beams where Y is an integer multiple of N. A distance between screen dots in pels is preferably equal to an integer multiple of N. The screen dot may be defined by a supercell encompassing two screen dots and having an odd number of pels in a direction that is parallel to the scanning direction. The spot function may include a snap feature that snaps a screen dot to the nearest printer grid pel. The spot function may include scaling to compensate for the distortion of the non-orthogonal screen dot.
Abstract:
Various embodiments described and illustrated herein provide one or more of systems, methods, software, and firmware to handle attack generated demand proactively using distributed virtualization. One goal of some such embodiments is to provide a time window of stable operational response within which an intrusion detection system may detect an attack and/or cause a countermeasure against the attacks to be activated. Demand excursions which are not caused by an attack are supported during the variability of demand providing transparent response to legitimate users of the system. These embodiments, and others, are described in greater detail below.
Abstract:
Provided are a method, system, and program for replicating a file. A file is copied to a target storage file system stored as a base file. A reference file comprising the copied file is generated at a local storage. An update is applied to the file at the local storage. A delta file is generated indicating differences between the updated file at the local storage and the reference file. A file system command is used to transmit the delta file to the target storage file system store to store in a directory of the target storage file system, wherein the file in the local storage is replicated at the target storage by a combination of the base file and the delta file.
Abstract:
A system and method for adaptive tarpits using distributed virtual machines. A method in an embodiment may include determining an intrusion prevention strategy in response to a potential attack on a network. Then, based on the intrusion prevention strategy, allocating at least one virtual tarpit in the network, where the at least one virtual tarpit is implemented as a virtual machine, and the adapting the at least one virtual tarpit in the network includes one or more of suspending a virtual tarpit, resuming a suspended virtual tarpit and migrating a virtual tarpit to another virtual machine in the network. Other embodiments are described and claimed.
Abstract:
Stable liposome composition for delivering a pharmaceutical agent, the composition comprising: (a) a suitable aqueous medium; (b) liposomes formed from a suitable phospholipid; (c) at least one pharmaceutical agent being at least partially encapsulated in the liposomes, and being selected from: (i) a lipophilic amine and a pharmaceutically acceptable acid, wherein the pharmaceutically acceptable acid is selected from an organic or inorganic acid, and (ii) a pharmaceutically acceptable organic acid salt of a lipophilic amine, and optionally a pharmaceutically acceptable organic acid; wherein the quantity of the pharmaceutically acceptable acid present in the composition is such that the pH of the liposome composition is less than or approximately equal to the pKa of the amino group of the pharmaceutically active lipophilic amine. Compositions, kits, and methods for the preparation of same, as well as methods for further enhancing the stability of the compositions by autoclaving, and methods for the identification of stable liposome compositions of the present invention are likewise provided.
Abstract:
Apparatus and methods are provided for treating female urinary incontinence by injecting a bulking agent at the interface between the mucosal and submucosal layers of the urethral wall. The remodeling device comprises an elongated shaft preferably having means for forming a localized inward protrusion of the urethral wall, and a needle, movable between retracted and deployed positions, for delivering a bulking agent into the urethral wall in the vicinity of the localized inward protrusion to thereby reduce or eliminate symptoms associated with urinary incontinence.
