| 20080291024 | Method and system for locating devices with embedded location tags - One embodiment of the present invention provides a system that locates a set of target transmitting mechanism using a mobile sensing infrastructure. During operation, the system determines a reference frame of a sensing mechanism by detecting signals from at least two transmitting mechanisms. The system further determines locations of the target transmitting mechanism relative to the reference frame using the sensing mechanism. In addition, the system produces a result to indicate the locations of the target transmitting mechanisms. | 11-27-2008 |
| 20080309468 | Human-machine-interface (HMI) customization based on collision assessments - One embodiment of the present invention provides a system that facilitates collision warning. During operation, the system receives information on one or more predicted collisions and determines a utility of issuing a warning for a predicted collision based on the received information. The system further schedules one or more warnings for the predicted collisions based on the utilities of issuing the warnings. | 12-18-2008 |
| 20080312830 | Using long-range dynamics and mental-state models to assess collision risk for early warning - One embodiment of the present invention provides a system that for facilitating assessment of collision between a primary principal and a non-primary principal for early warning. During operation, the system periodically performs the following operations: The system obtains a current observation of the primary principal and non-primary principal. The system then assesses one or more future states for the primary and non-primary principals, respectively, based on: the current observation of the primary and non-primary principals, a dynamics model of the primary principal, and a mental-state model of a person associated with the primary principal. The system further produces one or more results which indicate an assessment of collision between the primary and non-primary principals. | 12-18-2008 |
| 20080312831 | Two-level grouping of principals for a collision warning system - One embodiment of the present invention provides a system that hierarchically groups principals to facilitate collision warning. During operation, the system obtains information on a number of principals and constructs one or more first-level groups of principals. Within a first-level group, the system constructs one or more second-level groups, thereby facilitating an assessment of probability of collision between a second-level group and a primary principal. | 12-18-2008 |
| 20080312832 | Dual assessment for early collision warning - One embodiment of the present invention provides a system that facilitates warning of collision between a primary principal and one or more non-primary principals. The system includes a triggering mechanism and a preliminary assessment mechanism. During operation, the triggering mechanism determines whether a trigger condition is met based on the state of the primary principal. When the trigger condition is met, the preliminary assessment mechanism generates one or more collision scenarios associated with the trigger condition, assesses a preliminary probability of collision in a collision scenario, and, based on the preliminary probability of collision in the collision scenario, activates a specialized assessment mechanism to assess a refined probability of collision in the collision scenario. | 12-18-2008 |
| 20080312833 | Using segmented cones for fast, conservative assessment of collision risk - One embodiment of the present invention provides a system that facilitates assessment of collision between a primary principal and a non-primary principal for early warning. During operation, the system receives information which indicates a state of the primary principal and a state of the non-primary principal. The system divides future time into a number of time intervals, and estimates a number of possible future states of the primary and non-primary principals, wherein each future state corresponds to a time interval. The system further represents the possible future states of the primary or non-primary principal as one or more geometric objects in a space of which at least one dimension indicates the time. In addition, the system determines a probability of collision between the primary and non-primary principals based on the geometric objects. | 12-18-2008 |
| 20090157352 | METHOD AND APPARATUS FOR USING MOBILE CODE FOR DISTRIBUTED DATA FUSION IN NETWORKED SENSING SYSTEMS - A sensing system includes a set of sensors and a data-fusing mechanism coupled to at least one of these sensors. In the set of sensors, at least one sensor is configured to store one or more measurement models for one or more phenomenon states.
