Abstract: A preferred apparatus for delivering an intravascular drug such as a sclerosing agent (or a microfoam sclerosing agent) to a varicose vein includes a catheter having three concentric tubes. The innermost tube has a guide wire lumen and an inflation lumen. The distal end of the innermost tube has an integral inflatable occlusion balloon in fluid communication with the inflation lumen. The intermediate tube has a lumen through which the innermost tube extends. The distal end of the intermediate tube has a self-expanding balloon with a plurality of fluid pores in fluid communication with the intermediate tube lumen. The outer tube has a lumen through which the intermediate tube extends. Sclerosing agent is dispensed through the intermediate tube to pores located at the distal end of the intermediate tube or in the self-expanding balloon. Veins are sclerosed as the self-expanding balloon is pulled through and ultimately out of the vein.

Abstract: A medicament tablet dispensing system and method dispenses any selected number of tablets, up to a maximum number, without a substantial delay associated with counting all of the tablets. A preset number of tablets are counted and stored in dedicated primary chambers. Furthermore, an overflow chamber is provided for temporarily storing and then dispensing tablets which are fed to the primary chamber after the primary chambers are filled with their respective number of tablets. In addition, a direct feed channel is provided for dispensing individually counted tablets. The chambers and direct feed channel can together dispense the selected number. It is also preferable that the chambers have subchambers, and that more than one subchamber be capable of being emptied during a single dispensing operation.

Abstract: Electronic mail software includes a main email component and a number installable components. The installable components include authoring/reading components for creating/reading different kinds of documents and mailbox components for listing different kinds of messages or for listing messages in different styles. The main email component provides an underlying graphical user interface for functions directly associated with the storage and transfer of electronic mail messages, and also handles all data bundling and unbundling required to transform a message created by an authoring component into a MIME compliant message. The authoring/reading components act like applications embedded within the email program and allow specific types of documents such as spreadsheets, graphics, databases, etc. to be created from within the email program and emailed directly.

Abstract: An improved electrical lockout mechanism includes a first connection means to a power source, and a second connection means to a power input terminal of the machine being protected. The machine includes a manually-operated ON/OFF switch. A switching element, which is coupled between the first and second connection means, selectively completes and breaks an electrical circuit between the first and second connection means in response to a control signal supplied thereto. A control circuit generates this control signal in a manner that prevents unwanted machine restarts. The switching element may be realized by an electromagnetic relay device, or by a thyristor-based switching device such as a triac device. The electrical lockout mechanism can be integrated with a power cord that delivers electrical power to a machine, or can be integrated into the machine itself.

Abstract: Methods and apparatus for supporting multiple UTOPIA bus masters on a single UTOPIA bus include coupling two UTOPIA bus masters via three signal lines (Ready, Request, and Grant), designating one of the masters a primary master and the other a secondary master, and coupling both bus masters to the same UTOPIA bus. When receiving cells from the UTOPIA bus, both masters accept cells and screen them (with a lookup table) to determine which cells are addressed to them. When transmitting cells, the primary master normally controls polling and PHY selection. The secondary master asserts the Request line during polling to indicate that it has a cell to send to a PHY that has responded positively to the polling. In response to the Request signal, the primary master asserts the Grant line and control of the bus is given to the secondary master for the next cell cycle. The presently preferred embodiment utilizes an arbitration scheme to assure fairness in allocating control of the bus.

Abstract: Interference caused by the propagation of a transmit signal transmitted from a transmit antenna to a receive antenna is effectively cancelled by an improved signal cancellation system. The system includes an interference cancellation signal generator that generates a time-delayed and amplitude-reduced representation of said transmit signal. A summing stage is operably coupled to the interference cancellation signal generator and the receive antenna. The summing stage subtracts the time-delayed and amplitude-reduced representation of the transmit signal from a receive signal to substantially cancel the interference. The interference cancellation signal generator preferably includes a novel programmable optical delay line that introduces a variable amount of optical delay to an optical signal derived from said transmit signal in addition to a thyristor-based sigma delta modulator that converts samples of the transmit signal to into a digital signal in the optical domain.

Abstract: A network switch includes at least one port processor and at least one switch element. The port processor has an SONET OC-x interface (for TDM traffic), a UTOPIA interface (for ATM and packet traffic), and an interface to the switch element. In one embodiment, the port processor has a total I/O bandwidth equivalent to an OC-48, and the switch element has 12×12 ports for a total bandwidth of 30 Gbps. A typical switch includes multiple port processors and switch elements. A data frame of 9 rows by 1700 slots is used to transport ATM, TDM, and Packet data from a port processor through one or more switch elements to the same or another port processor. Each frame is transmitted in 125 microseconds; each row in 13.89 microseconds. Each slot includes a 4-bit tag plus a 4-byte payload. The slot bandwidth is 2.592 Mbps which is large enough to carry an E-1 signal with overhead. The 4-bit tag is a cross connect pointer which is setup when a TDM connection is provisioned.

Abstract: A weighing apparatus includes a SAW oscillator and a “push oscillator” to force the SAW oscillator into a desired mode of operation. A SAW temperature oscillator and a thermistor are also provided. The frequency of the “push oscillator” is made immune to temperature changes by generating it via a mixer mixing the SAW temperature oscillator with an adjustable fixed frequency oscillator. Long term stability of the SAW temperature oscillator is achieved by periodic calibration with the thermistor.
