In a method and apparatus for locating in a three dimensional data array an arcuate object having an axial extent, slices of data generally transverse to the axial extent of the object are selected. Rays generally radially of the arcuate object are selected within the slices. Crossing points where the rays cross the boundaries of the arcuate object are located. The position of the arcuate object is determined from the positions of the located points.

A system and method for receiving, at a packet-network telephone, a user message stored at a network device. Receiving the user message includes the packet-network telephone receiving a SIP message comprising an identifier that identifies (i) the user message, and (ii) a message transport protocol for retrieving the user message. The packet-network telephone transmits a request message addressed to the network device. The request message is arranged according to the message transport protocol and includes (i) at least a portion of the identifier so as to identify the user message, and (ii) a request for the user message to be transmitted to the packet-network telephone. The network device transmits the user message according to the message transport protocol. The packet-network telephone receives the user message, for presentation of the user message as the message is received or at a time subsequent to the packet-network telephone receiving the user message.

A method for offloading encryption and decryption of a message received at a message server to one or more end devices that are remote from the message server. An encrypting end device remote from the message server encrypts a message using cryptographic context and transmits the cryptographic context and encrypted message to the message server for storage at the message server. The message server stores the encrypted message as received without decrypting the message. The message server sends the stored cryptographic context and the encrypted message to a decrypting end device in response to the decrypting end device sending a request for the message server to transmit the encrypted message to the decrypting end device. The decrypting end device uses the cryptographic context to decrypt the encrypted message and then presents the decrypted message to a user of the decrypting end device.

This invention pertains to simplifying the modification of a process flow implemented by computer software. That is, an order of presentation of sets of data, which may be web pages, is defined in one repository so that any changes that need to be made to the order may be made in the one location, instead of having to make the change in multiple locations. The one repository, therefore, acts as a navigation repository that stores, in one location, the navigation information needed to advance from one set of data to another.

A method and a system for generating a panoramic x-ray image by obtaining volumetric x-ray image data having a first plurality of slices, segmenting the x-ray image data into a first portion above a vertical threshold and a second portion below the vertical threshold, and separating the second portion into a second plurality of slices. Further, the method and the system include generating a plurality of curves for each slice in the second plurality of slices, generating a master arch for the second plurality of slices, and generating a panoramic image based on the master arch.

In addition to alkyl benzenes, the composition also contains an antioxidant, an antifoaming agent, a pour point dispersant, a corrosion inhibitor and a detergent-dispersant additive, an extreme pressure additive, a lubrication additives, comprising of the following steps (I) removing of insoluble matter from the base stock, (II) tailoring the base stock by vacuum distillation and blending, (IV) removing the oxidized matters by adsorption, (V) addition of performance additives and homogenizing the mixture. The product of this invention has utility as an general purpose hydraulic fluid.
摘要:
A method and apparatus for generating a panoramic image of part of a target, comprises providing a scanner having a source of penetrating radiation facing a detector having an array of sensors for the penetrating radiation. The target is positioned between the source of penetrating radiation and the detector, and scanned with relative rotation of the scanner and the target. Radiation received at a plurality of the sensors spaced apart in the circumferential direction of the relative rotation is separately recorded. A panoramic image is generated by combining for each pixel of the panoramic image outputs from different sensors at different times during the relative rotation, the combined outputs being selected to represent rays of radiation passing through a point on a defined curve. The generated panoramic image and a graphical representation of the defined curve are displayed. Instructions are received from a user to alter the defined curve. The generating and displaying of the panoramic image are repeated using the altered curve.

This invention provides a composition of lubricating oil for two stroke gasoline engine and a process for the preparation thereof. In addition to alkyl benzenes, the composition also contains an antioxidant, an antifoaming agent, a pour point dispersant, a corrosion inhibitor and a detergent-dispersant additive, an extreme pressure additive, a lubrication additives, comprising of the following steps (D) removing of insoluble matter from the base stock, (II) tailoring by vacuum distillation, (III) blending of different alkylates, (IV) removing the oxidized matters by adsorption, (V) addition of performance additives and homogenizing the mixture. The product of this invention has utility as lubricating oil for two stroke gasoline engine in both water-cooled and air-cooled two-cycle gasoline engines producing reduced smoke.
摘要:
In one embodiment of a method of and apparatus for correcting for scatter, an object, which may be the jaw of a dental patient, is subjected to x-rays or other penetrating radiation. An intensity distribution of the transmitted radiation is detected. A first array of voxel data representing the absorption of the radiation by the object is reconstructed from the detected intensity. A radiation scatter pattern is calculated by forward projection from the first array using one or more point spread functions. The detected intensity is corrected using the calculated radiation scatter pattern. A second array of voxel data representing the absorption of the radiation by the object is reconstructed from the corrected detected intensity.
