    摘要: Described is a way for computing proximity (location-based proximity or preference-based proximity) between mobile wireless subscribers (who use different services) without either divulging their location/preference to the other (preservation of privacy). Privacy is kept by providing location/preference information in steps, along with an evaluation function. The services receive partial results and then locally compute the final result, or proximity. The term proximity includes not just physical proximity but also multi-dimensional data such as preference profiles and vectors (e.g., an affinity for baseball, apple pie, and ballroom dancing).

    摘要: An item of value to one or more individuals in a group is tracked wherein each valuable object is tagged, and one or more members of the group carry a personal information management (PIM) device equipped with a sensor which constantly scans for the presence of a known valuable. The sensor is able to detect the type of tag(s) used by the group of individuals. Whenever a member of the group carrying a PIM device comes across a known tagged valuable, the system detects it and logs the location, valuable ID, and user ID in a database. Optionally, visual data is captured from the valuable and compared against a standard located in a database in order to locate the valuable.

    摘要: A message pathway selection system dynamically selects an optimum message pathway for transmitting messages. The system dynamically optimizes a message pathway according to various criteria such as, for example, efficiency, economy, data requirements, auditing requirements, security, data size, etc. The system can direct a message to bypass an infrastructure messaging server, using a direct message pathway. The system can also switch from an infrastructure messaging server to a direct method. The system can also utilize an infrastructure messaging pathway either as an alternative or in parallel with the direct message pathway. The system allows an application to use a single communication system for both a direct mode and an infrastructure mode of data transfer. The present system can bypass the infrastructure message pathway, thus reducing message latency, number of messages sent, and improving overall bandwidth.

    摘要: A nonvolatile magnetic random access memory (MRAM) is an array of individual magnetic memory cells. Each memory cell is a magnetic tunnel junction (MTJ) element and a diode electrically connected in series. Each MTJ is formed of a pinned ferromagnetic layer whose magnetization direction is prevented from rotating, a free ferromagnetic layer whose magnetization direction is free to rotate between states of parallel and antiparallel to the fixed magnetization of the pinned ferromagnetic layer, and an insulating tunnel barrier between and in contact with the two ferromagnetic layers. Each memory cell has a high resistance that is achieved in a very small surface area by controlling the thickness, and thus the electrical barrier height, of the tunnel barrier layer. The memory cells in the array are controlled by only two lines, and the write currents to change the magnetic state of an MTJ, by use of the write currents' inherent magnetic fields to rotate the magnetization of the free layer, do not pass through the tunnel barrier layer. All MTJ elements, diodes, and contacts are vertically arranged at the intersection regions of the two lines and between the two lines to minimize the total MRAM surface area. The power expended to read or sense the memory cell's magnetic state is reduced by the high resistance of the MTJ and by directing the sensing current through a single memory cell.

    摘要: A thin film cobalt alloy magnetic recording disk has a metal nitride layer located between the disk substrate and the top surface of the disk to provide texturing of the disk at the head-disk interface. The texturing layer is made up of generally contiguous clusters of aluminum nitride (AlN) with rounded upper surfaces that are formed on top of the substrate and under the conventional Cr underlayer. The AlN texturing layer is formed by sputtering an Al target in the presence of N.sub.2 gas. The subsequently sputter-deposited Cr underlayer, cobalt alloy magnetic layer and protective amorphous carbon overcoat replicate the upper surface of the contiguous AlN clusters, resulting in a textured surface at the head-disk interface. The AlN texturing layer may also be sputter deposited above the magnetic layer in the middle of the protective carbon overcoat. The density and size of the AlN clusters in the texturing layer, and thus the texture of the completed disk at the head-disk interface, are controlled by the amount of N.sub.2, the sputtering power and pressure, and the substrate temperature.
