Abstract: A basic architecture for managing digital identity information in a network such as the World Wide Web is provided. A user of the architecture can organize his or her information into one or more profiles which reflect the nature of different relationships between the user and other entities, and grant or deny each entity access to a given profile. Various enhancements which may be provided through the architecture are also described, including tools for filtering email, controlling access to user web pages, locating other users and making one's own location known, browsing or mailing anonymously, filling in web forms automatically with information already provided once by hand, logging in automatically, securely logging in to multiple sites with a single password and doing so from any machine on the network, and other enhancements.

Abstract: Ultrasound contrast agents are used to enhance imaging and facilitate HIFU therapy in four different ways. A contrast agent is used: (1) before therapy to locate specific vascular structures for treatment; (2) to determine the focal point of a HIFU therapy transducer while the HIFU therapy transducer is operated at a relatively low power level, so that non-target tissue is not damaged as the HIFU is transducer is properly focused at the target location; (3) to provide a positive feedback mechanism by causing cavitation that generates heat, reducing the level of HIFU energy administered for therapy compared to that required when a contrast agent is not used; and, (4) to shield non-target tissue from damage, by blocking the HIFU energy. Various combinations of these techniques can also be employed in a single therapeutic implementation.

Abstract: A method and system for allowing a user of a computer program to select an option whereby adjacent characters in written words are automatically distinguished from each other on the screen. Variations in font size, color, appearance (e.g., blinking) are some examples of the types of variations proposed, as well as combinations thereof. By allowing variation of the characters of a word on a written page, each individual character receives independent focus by the user rather than having all of the characters receiving a “group” focus. This assists users with visual disabilities, such as dyslexia, in reading and writing on a computer screen.

Abstract: A method of obtaining data useful for one or more network applications is described. The method is performed responsive to a triggering event, such as a dropped call, a position fix, or even expiration of a timer. A position estimate for a subscriber station is obtained responsive to the event. A record is then formed associating the position estimate for the subscriber station with an identifier of the triggering event and/or data measured or obtained responsive to the event, such as the strength of one or more pilots visible to the subscriber station. The record is either stored locally or transmitted to a remote location. In one implementation, the record is transmitted to a remote location, and stored in a database holding like records relating to other subscriber stations.

Abstract: An improved therapy for both clearing the blood of unwanted carbon monoxide and anaesthetic chemicals and for rapidly re-oxygenating blood suffering from carbon monoxide poisoning or smoke inhalation. It also includes a therapy delivery device for carbon dioxide and oxygen metering and mixing apparatus for gases under pressure particularly for respirators and medical devices which has a plurality of compressed gas supply lines which are connected to a mixing device for delivery into a demand regulator (respirator or face mask). It includes a gas selection device, an automatic shut off of the carbon dioxide, a purging system, metering of the gases and a mixing chamber to promote a homogeneous mixture of gases and sized for field use by emergency care operators. The therapy is a mixture of carbon dioxide and oxygen for promoting the rapid oxygenation of the patient's blood supply for cases of carbon monoxide poisoning, smoke inhalation or other cases where the blood oxygen level is low.

Abstract: An alternative method, system and apparatus for addressing an e-mail message are provided. The alternative method, system and apparatus include using a physical location to address the e-mail message. The physical location may be a street address; however, whether a physical location or a street address is used, Global Positioning System (GPS) coordinates are used to forward the message to its destination. The message may include a range outside of which it is not retrievable. The message may further include a maximum number of recipients that may retrieve it as well as a time span outside of which it is not retrievable.

Abstract: A system, apparatus and method of delivering an e-mail message to a recipient are provided. Before a message is delivered to a recipient, a determination is made as to whether the recipient is within a particular range from a physical location to which the message was sent. The range may be a default range or one specified by the sender of the message. If the user is within the range, the e-mail message is delivered to the recipient; otherwise, it is not.

Abstract: A method, system and apparatus for receiving e-mail messages sent to physical locations are provided. To receive an e-mail message sent to a physical location, a recipient must be within a range from the physical location. The range may be a default range or may be specifically identified by a sender in the message. Furthermore, although the recipient may be within the range identified in the message, the recipient may still not receive the message if a time-span within which the content of the message is current has elapsed.

Abstract: An improved electrically operated pilot-type, “instant-on” solenoid assembly for near-instantaneous control over the flow of compressed gas. The assembly may be applied in fuel systems for propulsion in vehicles using gaseous fuel. It includes a housing with inlet and outlet passages connected to a primary chamber where a primary piston is slidably mounted, a secondary chamber having a secondary piston slidably mounted within the chamber, a solenoid to produce translational movement of the pilot piston, and passageways linking the various components. When the solenoid is energized, the pilot piston is moved to permit fluid to flow from the primary to the pilot chamber, producing an increase in the differential pressure in the regions of the primary chamber. The differential pressure then forces the primary piston to move, exposing the outlet to fluid flow from the gas inlet.

Abstract: A system of operating a wireless handset capable of making clear and secure calls is claimed. A secure call may be made by pressing a key for a predetermined amount of time. The handset enters a secure mode if the key is held for a time period greater than the predetermined amount of time. The handset enter is a clear mode if the key is held for a time period less than the predetermined amount of time.

Abstract: A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.

Abstract: A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source includes a body having an inlet, and a pressure regulating chamber disposed in the body. A high pressure fluid circuit extends between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber. The high pressure fluid circuit includes at least two longitudinally extending high pressure passages in fluid communication with each other. One longitudinally extending high pressure passage transmits the fluid in a first direction, and another longitudinally extending high pressure passage transmits the fluid in a second direction different than the first direction.

Abstract: A device for removing accumulated cerumen and a method for using the same, which device consists of a small balloon-tipped catheter inserted directly over the tip of a syringe or through the use of a plastic insert extended over the tip of a syringe, which balloon tip, when deflated, will fit easily into the auditory canal and, when inflated by depressing the plunger of the syringe, will provide a base for, when the syringe is removed from the ear canal, accumulating the blockage or excess cerumen thereon.

Abstract: A digital gas metering system includes inlet and outlet manifolds, a plurality of conduits each extending between the inlet manifold and the outlet manifold, and a solenoid-operated valve in each conduit. At least one of the valves is a tri-stable valve. Each tri-stable valve has a highest flow setting, a lowest flow setting, and an intermediate flow setting. The preferred embodiment utilizes at least two tri-stable valves, and these have respective highest flow settings which form a geometric progression in which each term is substantially triple the preceding term.

Abstract: A tri-stable, solenoid-operated valve defines an internal chamber communicating with an outlet passageway and an inlet passageway, with a valve seat surrounding the outlet passageway. A first piston reciprocates toward and away from the valve seat and supports a closure adapted to close the valve when the first piston is in a first position, and to be spaced away from the valve when the first piston is in a second position. A second piston is mounted to the first piston and can reciprocate toward and away from the valve seat. The second piston has a portion which projects into the outlet causing partial occlusion when the first piston is in its second position and the second piston is in its first position. The portion of the second position causing the outlet to be occluded is substantially withdrawn when both pistons are at their respective second positions.

Abstract: The present invention provides a supplementary pressure regulator that can be used with conventional single or multi-stage pressure regulators. It may also conveniently be used with a novel two stage balanced pressure regulator to form a three-stage vacuum demand pressure regulation system which may be used to regulate the pressure of compressed gases used as fuel in engines, such as natural gas used in natural gas powered vehicles. The pressure regulator of the present invention is a robust, compact, high flow, low droop, low pressure drop, low set-point drift and low creep regulator which is suitable for both OEM and after market use. It is particularly useful in mono-, bi-, and dual fuel engine applications.

Abstract: The present invention provides an improved two-stage pressure regulators for various compressed gases, and more particularly to pressure regulators used for gaseous fuels such as compressed or liquified natural gas. The pressure regulator of the present invention is a robust, compact, high flow, low droop, low pressure drop and low creep regulator which is suitable for both OEM and aftermarket use. It can be used by itself, or with an optional third stage to provide a three stage regulator such as the atmospheric (or zero pressure differential) types commonly used to regulate the fuel pressure for gaseous carburetion systems. It is particularly useful in mono-, bi-, and dual fuel engine applications.
