Abstract: The present invention relates to a new intravascular imaging device based on a Shape Memory Alloy (SMA) actuator mechanism embedded inside an elongate member such as a guide wire or catheter. The present invention utilizes a novel SMA mechanism to provide side-looking imaging by providing movement for an ultrasound transducer element. This novel SMA actuator mechanism can be easily fabricated in micro-scale, providing an advantage over existing imaging devices because it offers the ability to miniaturize the overall size of the device, while the use of multiple transducer crystals maximizes field of view. Also disclosed are methods of using the same.

Abstract: The present invention relates to a new intravascular imaging device based on a Shape Memory Alloy (SMA) actuator mechanism embedded inside an elongate member such as a guide wire or catheter. The present invention utilizes a novel SMA mechanism to provide side-looking imaging by providing movement for an optical coherence tomography (OCT) element. This novel SMA actuator mechanism can be easily fabricated in micro-scale, providing an advantage over existing imaging devices by offering the ability to miniaturize the overall size of the device. Because the device does not require a rotating shaft or fiber optic along the length of the catheter, it also allows for a more flexible catheter or guide wire, and provides room for other interventional devices. The device simplifies the manufacture and operation of OCT by allowing a straight fiber optic directed by an independent, oscillating reflector or prism controlled by the actuator mechanism located only in the distal tip of the device.

Abstract: A server machine has a first user interface for interactively producing templates and a second user interface provided through a client machine, such as a wireless telephone, for performing server actions using templates. In response to signals received through the first user interface, the server produces a template for use in performing server actions, such as creating e-mail messages, scheduling appointments, or submitting database queries. The template includes a field and a attribute data indicating whether it is necessary to obtain information through the second user interface to complete the field. The server receives a request from the client machine for performance of a server action using the template. In response, the server performs the server action, determining from the attribute data whether it is necessary to obtain information to complete the field. If not, the server performs the server action without obtaining information through the second user interface to complete the field.

Abstract: An intermediate system provides remote clients with access to a primary system, such as a server. The intermediate system creates and stores a log-in record for each client. The log-in record contains an encrypted primary system client identifier (PSCI). The PSCI contains authentication information for verifying a client's right to access the primary system. Storing an encrypted version of the PSCI enhances the security of the authentication information on the intermediate system. In some implementations of the present invention, the PSCI itself is an encrypted value. When a client attempts to log into the primary system, the intermediate system initially verifies the client's intermediate system access rights. The intermediate system makes this determination using the log-in record and data provided by the client. Next, the intermediate system sends the PSCI to the client's primary system for further authentication. The primary system uses the PSCI to verify the client's right to access primary system data.

Abstract: An intermediate system provides remote clients with access to a primary system. The intermediate system creates and stores a log-in record for each client. The log-in record contains an encrypted primary system client identifier (PSCI) and a security scheme identifier (Security ID). The PSCI contains authentication information for verifying a client's right to access the primary system. The Security ID identifies the security scheme employed to secure information for a client's log-in process. The intermediate system initially verifies a client's access rights using the security scheme identified by the Security ID and data provided by the client. Next, the intermediate system sends the PSCI to the client's primary system, which uses the PSCI to verify the client's access rights. When necessary, a security scheme update modifies values in the client log-in record. The update modifies values that depend on log-in data provided by the client, including modifications to the encrypted PSCI.

Abstract: A server machine transfers a version of an e-mail for presentation by a client machine. The version includes a user-understandable descriptor of an attachment to the e-mail but does not include the attachment. The server receives a request from the client to transfer the attachment for rendering. In response, the server obtains an output version of the attachment and transfers the output version to a rendering device, causing the rendering device to produce a rendered version of the attachment. The client machine can have a display, and the user-understandable descriptor can be visible on the display. The descriptor can be a selectable item; in response to selection of the descriptor, the server can transfer options to the client, including options that involve rendering an attachment. For an image attachment, the rendering options can include printing, sending to a copy shop, and sending to a fax machine.
