摘要:
A method of transmitting information in a network includes receiving, at a node, a data sample having a microutility associated with the data sample, the microutility including information as to how the data sample is to be handled in transit. The receiving node evaluates the microutility using information available at a receiving time on the receiving node and information encoded in the microutility to determine propagation characteristics of the data sample and propagates the data sample to other nodes in the network in accordance with the propagation characteristics.

An information dissemination system has at least one node acting as a data source, at least one node acting as a data recipient, and an information layer residing on all of the nodes in a system. The information layer receives a generic utility function from an application on the node acting as a data source wanting to propagate information, uses the generic utility function at the node acting as data source to produce a microutility and uses the microutility on non-data source nodes of the system to propagate the information through the system to any recipients based upon the microutility.
摘要:
A method of transmitting data includes determining how much data is desired to be transmitted from a data source. A utility function is used to determine a pattern of microutilities to be associated with data samples from the data source. The pattern of microutilities specifies a pattern of data delivery to at least one predetermined location relative to the data source. The data samples are propagated according to the pattern of microutilities.
摘要:
A method of managing traffic in an ad-hoc network includes receiving, at a local node, a received synopsis of data sample updates in a neighbor storage of a neighboring node, the synopsis being based at least in part on dynamic priorities associated with the data samples. The received synopsis is then compared with data sample updates in a local storage of the local node and the local node determines which data samples will be transmitted.

摘要:
A method of managing traffic in an ad hoc network determines local data traffic levels at a node, and uses the local data traffic levels to define a criteria. The criteria is applied to a microutility associated with the data sample to determine if the data sample should be propagated, temporarily delayed or dropped.
摘要:
Techniques are provided for creating and sharing information about arbitrary documents. A primary document is selected and a document content identifier generated based on the content of the primary document. Additional information such as comments, additional documents, reviews and the like are created and/or selected from an information repository. The additional information is associated with the primary document based on the document content identifier of the primary document. A search for information associated with the primary document compares the document content identifier of the primary document to document content identifiers associated with the additional information. Additional information associated with the document content identifiers matching the primary document content identifier is retrieved and displayed to the user.
摘要:
Techniques are presented for determining threshold probability or confidence levels for associating various types of health information with a set of users. Spatio-temporal information associated with one or more of the subjects is determined. Health information associated with spatial-temporal information is also determined. Candidate health-subject associations are associated with probabilities based on the spatio-temporally tagged identity and spatio-temporally tagged health information. Candidate health-subject associations with probabilities exceeding a threshold probability level are assigned as actual health-subject associations. Treatment plans, reports, remedial procedures and or other health related tests, procedures or the like are determined based on the associated health information.
摘要:
This disclosure introduces a system which generates a visual, audio, and/or tactile warning to a driver of a lead vehicle when a possible rear-end collision is detected, based on the approach of a second vehicle from a rear direction. The system may also generate a warning signal (such as quick blinking red brake light, or an array of multi-color lights) directed to the approaching vehicle when it is determined to be approaching at an unsafe speed. The system may include one or more of: approaching-vehicle-sensors mounted on the back end of the lead vehicle, a computer processing system, a set of warning lights, a set of speakers within the lead vehicle, and an antenna and transmitter/receiver for communicating with systems of other vehicles. This system may include a connection to the existing taillight system and other existing systems in the lead vehicle. Extended systems may include connections to and control of head support system, seat-belt systems and airbags system to provide additional safety to the occupants of the lead vehicle. The system may also record and store a few seconds of sensor data of the pre-crash and crash related scene when an impact occurs, and provide blind spot warnings.
摘要:
A process for producing a low-visibility retroreflective visual tag, which can be used to identify and/or determine the position of an object. This process involves placing an infra-red-blocking material over a retroreflective substrate to form the low-visibility retroreflective visual tag. This infra-red-blocking material is placed so as to form a pattern, which becomes visible to an infrared sensor when the low-visibility retroreflective visual tag is illuminated by an infra-red light source.
