Title: Catheter centering device
Inventor: STINSON JONATHAN SWIFT
IPC: A61F2/958
Filed: 1998-03-19
Abstract: A medical device (10) for treating a body vessel (42) with a radioactive source (16) includes an elongated tubular catheter (14) and an axially flexible support structure (12) on a distal end of the catheter (14). The catheter (14) has proximal and distal ends, and a lumen (18) for receiving a radioactive source (16). The support structure (12) is formed from a plurality of filaments (22) which are helically wound and interwoven in a braided configuration and has a plurality of alternately spaced unconstricted (32) and constricted (30) regions. The unconstricted regions (32) are radially compressible and self-expandable from a positioning diameter when the device (10) is in a positioning state to a vessel-engaging, treatment diameter which is greater than the positioning diameter when the device(10) is in the treatment state. The constricted regions (30) are engaged with the catheter (14) and concentric with the unconstricted regions (32). When in the treatment state the support structure (12) causes the catheter (14) to be substantially radially centered within a vessel (42) so radiation is uniformly applied to the vessel (42) during treatment.

Inventor: MARSH BRIAN D
IPC: G06Q10/10
Filed: 1997-04-11
Abstract: The present invention provides a method and apparatus for scheduling the presentation of a continuously-changing display (702) to computer users, and is particularly well-suited for use in an advertisement-supported e-mail service. An advertisement display scheduler (700) resident on a user's computer receives advertisements from a server system over a network. Upon receipt, the advertisement display scheduler (700) determines the priority of the advertisement (MSG01 ....      MSGnn) and assigns it to one of a plurality of prioritized advertisement queues (Qo ....      Qn). Each queue is sorted (701) according to predetermined scheduling criteria so that advertisements deemed "more important" are presented to a user first. The advertisement display scheduler (700) logs statistical information relating to the presentation of advertisements for use in updating the scheduling criteria, and makes such statistical information available to the server system.

Abstract: Totally anonymous or effectively anonymous cash-like transactions are accomplished by using a pseudo cash data packet converter for inserting a user key into a pseudo cash preliminary data packet through the use of a user monetary value that can be used to purchase goods or services via the Internet. A pseudo cash repository facilitates the cash-like transactions and maintains a record of the pseudo cash units and their fixed monetary value.  Depending upon the level of anonymity selected by a purchaser (1), the pseudo cash repository can either transmit pseudo cash preliminary data packets or pseudo cash units to a first entity. If the first entity loses an effectively anonymous pseudo cash preliminary data packet, it can be replaced by the pseudo cash repository without risk of loss.

Title: On-site concrete truck wash-out apparatus
Inventor: BARRY C MARVIN
IPC: B08B9/00
Filed: 1999-03-30
Abstract: This application relates to an apparatus for containing and filtering rinse water, sediment and aggregate resulting from washing the hopper and discharge chute components of a concrete truck at a construction site following use, The apparatus comprises a container removably mountable on the end of the discharge chute, the container having an open upper end, a screen removably positionable within the container and an outlet located in a lower portion of the container below the screen. The apparatus further includes a pump mountable on the truck, the pump having a suction hose extending between the container outlet and the pump; and a discharge hose extending from the pump to an open end discharging into the mixing drum. When the pump is operating, rinse water and relatively small particle size sediment flushed down the chute and into the container is automatically conveyed through the suction and discharge hoses into the mixing drum. The screen has openings approximately 1/4 inches in diameter to trap relatively large particle size aggregate thereby preventing clogging of the pump fittings. The apparatus avoids the need for a designated truck wash-off station at the construction site and prevents contamination of the site or adjoining waterways with cementitious debris.

Title: Latency counter for scanning timers
Inventor: HOLMLUND JONAS
IPC: H04M3/22
Filed: 1997-11-11
Abstract: A latency counter for use in relatively complex systems having relatively large numbers of devices with associated timers. Whenever a timer is activated by setting a time period, the latency counter is set to the larger of its current value or a value associated with the time period of the last-expiring timer. Prior to scanning the timers to determine if a timer has expired, the latency counter is checked. If the value of the latency counter is equal to a predetermined value, then no timers are active and no scanning is performed. If the value of the latency counter is not equal to the predetermined value, the latency counter value is modified and a scanning operation of each timer is perfomed to determine if any timers have expired. Considerable processing resources can be saved.
