摘要:
This invention provides a method and system for data encryption and decryption in data transmission through the web. The method includes: a browser sends a cryptographic information acquisition request to a cryptographic information providing equipment; the cryptographic information providing equipment sends cryptographic information back to the browser via an HTTPS channel; the cryptographic information includes a cryptographic algorithm and a cryptographic index; the browser uses the cryptographic algorithm to encrypt the data to be transmitted, and sends the encrypted data and the cryptographic index to the web server via an HTTP channel; the web server obtains the cryptographic algorithm corresponding to the cryptographic index from the cryptographic information providing equipment, then decrypts the encrypted data. Embodiments of the present invention can alleviate the load in the HTTPS channel, and improve the overall performance.

This invention relates to a chemically-modified polybenzimidazole porous tube. The tube has an outer diameter of 100-1000 microns, a wall thickness of 20-100 microns, and a pore size of 0.1-0.5 nm.
摘要:
A hollow fiber includes a lumen, a polymeric membrane defining the lumen, and a porous tubular substrate, a circumferential surface of which is in contact with a circumferential surface of the polymeric membrane. The polymeric membrane includes a first polymer having monomers each containing an imidazole group. The hollow fiber can be used for water reclamation and protein enrichment
摘要:
Systems and methods for monitoring equilibrium of a user are presented. A stability monitoring device in a shoe insole area utilizes pressure sensors to measure pressure information in real-time. The pressure information is transmitted over an RF network to a device for analyzing the pressure information and calculating postural state information including the current postural state, next postural state, and/or a range of postural stability. The person or a third party may be notified if the postural state information indicates an unstable state. Additionally, the postural state information may be analyzed to determine activity level of the user, diagnostic information, or performance information. Metrics may be displayed by the system for assisting physical therapy or training regimens.
摘要:
Methods and apparatus are provided for subscribing to dynamic attributes. One or more users are notified of information having a plurality of attributes, including at least one dynamic attribute. According to one aspect of the invention, a user can enter a subscription request to be notified when the at least one dynamic attribute changes a value. For example, the subscription request can notify user when the dynamic attribute (i) changes a value to one or more predefined values; (ii) changes to satisfy a user specified condition; or (iii) changes to a value within a specified range of values. The subscription request can optionally include one or more temporal conditions. For example, the temporal conditions can evaluate whether the dynamic attribute satisfied a value constraint during a given time interval.
摘要:
Methods and apparatus are disclosed for notifying one or more users of information. One or more users are identified that have entered a subscription that matches the information; and a communication flow expression is generated that contains at least one primitive keyword indicating how a notification to the identified users should be processed. The communication flow expression may be provided, for example, to a third party for delivery. Typically, a request identifier is received back from the third party and forwarded to the application associated with the information. The communication flow expression comprises at least one recipient for the notification. The identified users may be required to have appropriate privileges associated with the information before being added to the communication flow expression.
摘要:
Methods and apparatus are disclosed for automatic notification and response based on communication flow expressions having dynamic context. A message is provided from a sender to at least one recipient in accordance with a communication flow having a plurality of potential paths. The communication flow is controlled by a communication flow expression having a dynamic context, wherein the communication flow expression contains at least one primitive keyword indicating how the message should be processed. The dynamic context of the communication flow expression may be established using one or more labels or a context function. A number of primitive keywords are provided that allow a communication flow expression to react to a dynamic context.
