Abstract: A system and method for automated filling of one or more medical syringes with desired volume(s) and concentration(s) of an injectate solution, such as a contrast solution usable for medical imaging procedures (e.g., x-ray, MRI, ultrasound). The system may incorporate an automated syringe magazine which interfaces with the programmable system controller to deliver the desired number of syringes after the syringes have been filled. Also, the system may utilize a low-pressure pumping arrangement wherein a pumping device engages each receiving syringe and withdraws the plunger of the receiving syringe to pull the desired injectate solution into the receiving syringe by negative pressure.

Abstract: A terminal emulation program for an IBM host is described. The program can record scripts (mini-programs) of IBM host sessions. For each action or event, as desired, the program records an appropriate script. Scripts may be created for connecting to and disconnecting from the IBM host, for sending key strokes, for sending playback-time inputs, for awaiting a certain screen, and for importing displayed IBM host data. The scripts are stored in a file on a PC and may be replayed either from the terminal emulator, from Windows, or via OLE.

Abstract: A system and method for reducing and removing and ophthalmic lens of a mammalian eye. The system includes a rotary lens-reducing probe device of either straight or curved configuration, said probe device comprising a tubular outer sheath through which a rotatable drive shaft extends. A rotating lens-reducing head member is positioned on the distal end of the drive shaft. The head member is configured and constructed to draw a flow of fluid and lens matter into contact therewith, thereby facilitating complete reduction of the entire lens without requiring significant axial (i.e., longitudinal) movement of the probe within the lens capsule. The distal portion of the tubular sheath is preferably configured to shield a portion of the lens-reducing head, during operation, to avoid inadvertent damage to lens capsule. Also, the distal portion of the sheath may be aimed or positioned to direct the flow of fluid and lens matter created by the rotating head in a preferred flow path within the lens capsule.

Abstract: A method of identifying computer screens is disclosed. The method is particularly useful in identifying IBM host screens in script creation and playback. According to the method, a signature is composed for a given screen. The signature comprises characteristics of a given screen which differentiate that screen from substantially different screen displays. For an IBM host screen, signature composition is based upon the screens protected fields. The protected fields are further processed by removing transient information such as the date and time.

Abstract: In a networked system having workstations, file servers and intelligent peripheral devices, the intelligent peripheral devices are capable of determining information concerning their device status and communicating the device status information via a communications line. The file server obtains the device status information from the peripheral device and stores this information as a file readable by the workstations.

Abstract: A pipelined bus which can support more than one channel between data sources and data destinations at a time. The bus includes an arbitration bus, a command bus and a data bus. In accordance with the bus protocol, different channels may access the various bus components in the same clock cycle. For example, the data source of one channel may issue a command on the command bus to its selected data destination to get ready to receive data while at the same time, a data source of a second channel actually transmits data on the data bus to its selected data destination. During the same clock cycle, a third data source can be selected by the arbitration bus to initiate or resume a channel.

Also included are methods for performing transvascular interstitial surgery (TVIS) wherein extravascular passageways are formed from a blood vessel to another vascular or non-vascular intracorporeal location. Also disclosed are devices usable for forming extravascular passageways in accordance with the invention, or for modifying, valving, maintaining or closing such passageways.

Abstract: A method of recognizing correspondence between a pre-recorded sample announcement and the identical pre-recorded reference announcement is shown. The reference pre-recorded sample announcement is characterized in terms of: (1) Start of speech (SP) where the transition from silence to voicing occurs, (2) average frame power (AFP) for each power frame length of a voicing segment of speech (3) silence gap length (SGL), the duration of non-voicing between two consecutive voicing segments and (4) end of speech (EOS). The sample pre-recorded announcement is also characterized in terms of SP, AFP, SGL, and EOS. The SP, AFPs, SGLs, and EOS of the reference pre-recorded announcement is compared with that of the sample pre-recorded announcement to determine if a match exists.

Abstract: In accordance with the invention, a traveler can use a portable computer to automatically retrieve voice mail from a PBX-based voice mail system or a telephone answering machine. The computer has a modem, an audio output system (e.g., SoundBlaster card and speakers) and a special program. During a training phase of the method, the program creates a script of normal interaction with the voice mail system. The script is used during a message retrieval phase to retrieve voice mail messages. Multiple scripts may be recorded. During the retrieval phase of the method, the program uses word spotting to compare prompts received from the voice mail system to prompts in the script to ensure that the process is working properly. The program can create script commands for: dialing the voice mail system; entering a mail box number and password; making appropriate selections to listen to new messages; recording the messages from the voice mail system into the portable computer; and disconnecting from the voice mail system.

Abstract: A method and apparatus wherein a germicidal lamp's tube is positioned in a particular manner relative to the HVAC system such that the system coil and drain pan components are subjected to UVC radiation and an increased flux density of photons emitted therefrom, and the photons are continuously reflected and directed within and through the coil until absorbed. In this manner the flux density of the photons is increased, as well as the dosage of the photons actually applied to a surface or airborne microorganism, minimizing the occurrence of HVAC-sourced bioaerosols and effectively and efficiently killing the mold and bacteria that grow on the coil and in the drain pan of a HVAC system without producing a secondary contaminant.

Abstract: An apparatus for mounting a radially expandable intraluminal stent or stented graft onto a delivery catheter. The apparatus comprises a hollow housing defining an interior chamber and a fluid port which communicates with the interior chamber. Disposed within the interior chamber of the housing is a collapsible, resilient tubular sleeve which is sized to receive a portion of the delivery catheter having the stent or stented graft positioned thereupon. The sleeve includes an open end which communicates with the exterior of the housing. The pressurization of the interior chamber of the housing via the fluid port facilitates the uniform radial compression of the sleeve, with the depressurization of the housing via the fluid port causing the sleeve to resiliently return to an uncompressed state.

Abstract: In a magneto-optical recording method and, more particularly, a bit position recording method, laser beam intensity is pulse-modulated between high and low levels according to data to be recorded. The modulated laser beam is radiated on a recording medium under the presence of a bias field. High-level emission time of the laser beam is shortened at the inner portion of the medium, and is prolonged at the outer portion. Low-level intensity of the laser beam is decreased at the inner portion of the medium, and is increased at the outer portion, thereby increasing C/N ratio upon reproduction.
