A hierarchical folder security system for mapping files into and out of alias directories and/or real directories depending on: 1) the directory of the specific file being accessed, 2) the program thread requesting access to a memory storage device (114), and 3) the type of access request being made (i.e. load, save, run, etc.). For write access requests (i.e. save, modify, paste, delete, cut, move, rename, etc.), security controller (180) determines if the requested folder access address (150a) is associated with the requesting program's folder address (168). If it is, the file is written at absolute address (156b) on disk platter (160) through real folder map (152). If requested address (150a) is not associated with program folder address (168), then an alias directory address is created and the file is written at alias address (156a) through alias folder address map (154).

A minimally invasive, implantable heart sound and ECG monitor and associated method for deriving blood pressure from heart sound data. The device is equipped with an acoustical sensor for detecting first and second heart sounds which are sampled and stored during sensing windows following R-wave and T-wave detections, respectively. ECG and heart sound data are stored in a continuous, looping memory, and segments of data are stored in long-term memory upon an automatic or manual data storage triggering event. Estimated blood pressure is calculated based on custom spectral analysis and processing of the first and second heart sounds. A calibration method includes measuring a patient's blood pressure using a standard clinical method and performing regression analysis on multiple spectral variables to identify a set of best fit weighted equations for predicting blood pressure. Concurrent ECG and estimated blood pressure may be displayed for review by a physician.

Certain commands, such as commands that may modify the storage device, may be discarded.

A system and method for storing and processing physiological data in a medical recording device that allows continuous data collection and storage of such data in multiple time-resolved levels are provided. The method includes: sampling one or more physiological signals at a selected sampling rate; deriving physiological parameter values from the sampled signal; storing the parameter values as they are determined in a temporary memory buffer for a predetermined storage interval; determining a statistical aspect of the stored parameter values upon expiration of the storage interval; and writing the statistical aspect to a long-term memory buffer. A number of long-term memory buffers may be designated for storing a statistical aspect of a physiological parameter at uniquely different time resolutions. The resolution of each long-term memory buffer is determined by the storage interval defined for an associated temporary memory buffer, which stores parameter values from which statistical aspects are computed.

A computerized method for collecting suspected data of interest from a computer comprises searching the computer's shot-term memory to locate at least one target memory range containing the suspected data of interest, and copying the suspected data of interest within the target memory range to an alternate data storage location in a manner which avoids writing the suspected data to the computer's long-term memory. Alternatively, the suspected data of interest can be copied to a previously unused data storage location while preserving integrity of non-volatile memory resources. A computer-readable medium and a system for collecting target forensics data are also provided.

The invention discloses a target tracking method based on target template updating. A target template base is established based on particle filtering principles under characteristic fusing and employing a video block multi-task means. The information of the next frame and target information in the target template base are matched and sorted by using color and edge characteristics. Template memory criteria are used to update the target template base, thereby realizing target long-term memory under different states. The target tracking method overcomes the defect that conventional video target tracking technology is likely to be influenced by external interference. Targets can be accurately positioned, and tracking errors can be effectively reduced.

Techniques are described for detecting anomalous events using a long-term memory in a video analysis system. The long-term memory may be used to store and retrieve information learned while a video analysis system observes a stream of video frames depicting a given scene. Further, the long-term memory may be configured to detect the occurrence of anomalous events, relative to observations of other events that have occurred in the scene over time. A distance measure may used to determine a distance between an active percept (encoding an observed event depicted in the stream of video frames) and a retrieved percept (encoding a memory of previously observed events in the long-term memory). If the distance exceeds a specified threshold, the long-term memory may publish the occurrence of an anomalous event for review by users of the system.

Methods are disclosed for instructing a player in a video game in a more effective manner. In an embodiment, a first fact is provided to a player and then the player is asked questions about the first fact, solidly placing the first fact in the player's short-term memory. Then a player is provided a second fact, interrupting the short-term memory of the first fact. The player is then asked a question about the first fact, interrupting the short-term memory of the second fact. A question is then asked about the second fact, interrupting the player's short-term memory of the first fact. Additional facts may be similarly handled. By the use of the strategic interruptions, the facts are pushed into the player's long-term memory deeper and more quickly than with the use of pure repetition of facts while they are in the player's short-term memory. The questions may be incorporated into virtual entities that the player is required to interact with. To improve gameplay, the player's input may be automatically processed once the player enters the expected number of digits associated with the expected answer.
