A lane-changing support system includes a processing unit sets an assumed traffic-merging end, predicts a driving behavior of each peripheral vehicle, and generates at least one host vehicle's manipulated-variable time series to be executed until the host vehicle reaches the assumed traffic-merging end. The processing unit determines whether the host vehicle's lane change is appropriately achievable when executing the manipulated-variable time series, and additionally determines which of gaps defined between the peripheral-vehicles traveling on a traffic lane of destination of lane-changing should be suited for an entry of the host vehicle in case of a decision result that the appropriate lane change is achievable by execution of the manipulated-variable time series. The processing unit transmits information regarding a correspondence between a current host vehicle's manipulated variable on the manipulated-variable time series and at least one lane-changing enabling gap to the driver.

A digital camera for having a variable time duration burst capture mode, comprising: an image sensor; an optical system; a data processing system; a frame buffer memory; and a program memory. The program memory stores instructions including: specifying a first frame rate; initiating an image capture sequence; storing a sequence of digital images captured at the first frame rate in the frame buffer memory; determining whether the frame buffer memory has been filled to a predetermined capacity. If the frame buffer memory has been filled to the predetermined capacity, the program memory further includes instructions for specifying a second frame rate, wherein the second frame rate is lower than the first frame rate; designating a set of stored digital images that can be overwritten; and storing a sequence of digital images captured at the second frame rate in the frame buffer memory, overwriting the designated set of stored digital images.

A method and system performs parallel processing of asynchronous processes on ordered entities. A system focuses on the average time and variance of the variable time process. Each processor can run multiple contexts. The processing may be divided into a number of stages, each of which can be performed by each of the processors. A system also needs to ensure that the order of the entities is preserved as desired. This order may be maintained by performing some type of pre-processing on the entities to determine their order, and then not starting processing on an entity until the processing of any entity which must precede that entity has been completed. For processing of packets in a network, it may be needed to ensure that packets in the same flow maintain their order after processing. A system also may determine the number of processors that optimally are needed in order to process an incoming stream of entities at a desired speed. This computation may depend on how many different contexts each processor runs. In addition, this computation also may depend on whether there is an input buffer available to store the incoming entities, and the capacity of such an input buffer.

When the user works at home on his home computer, a work monitor logs his file activities on all the drives of his home computer in a work monitor log, which can be displayed in a work monitor window. The user can choose to update from the work monitor window. When update is selected, the files in the work monitor log are selected for file synchronization. When file synchronization is performed, files on the user's home computer are synchronized with corresponding files on the user's office computer. Preferably, the date and time of a file on the home computer selected for file synchronization are compared to the corresponding date and time of the corresponding file on the office computer to determine the direction of file synchronization. The newer version of the file overwrites the older version of the file on either the home or office computer. The file activities which qualify for logging in the work monitor log are selectable by the user as either accesses to the file, for example, reading a file without necessarily writing over it, or as file modification, which requires that the user writes the file. The generation of the work monitor log involves logging each file activity when the work monitor is enabled by the user. The user may wish to disable the work monitor for periods of time for various reasons. The user may select a variable time period for which log entries are maintained in the work monitor log, for example one week. Work monitor log entries are deleted from the work monitor after they have been in the work monitor log for more than the variable time period.

An architecture and method for performing coarse-grain reservation of lightpaths within wavelength-division-multiplexed (WDM) based photonic burst-switched (PBS) networks with variable time slot provisioning. The method employs extensions to the RSVP-TE signaling protocol, which uses various messages to reserve resources. A resource reservation request is passed between nodes during a downstream traversal of the lightpath route connecting a source node to a destination node via one or more switching nodes, wherein each node is queried to determine whether it has transmission resources (i.e., a lightpath segment) available during a future scheduled time period. Soft reservations are made for each lightpath segment that is available using information contained in a corresponding label. If all lightpath segments for a selected route are available, a reservation response message is sent back upstream along the route from the destination node to the source node. In response to receiving the response, the soft reservations are turned into hard reservations at each node.

A method is disclosed for separating energy resulting from actuating at least two different seismic energy sources from seismic signals. The sources are actuated to provide a variable time delay between successive actuations of a first one and a second one of the sources. The method includes sorting the seismic signals such that events therein resulting from actuations of the first source are substantially coherent in all spatial directions, coherency filtering the first source coherency sorted signals, sorting the seismic signals such that events therein resulting from actuations of the second source are substantially coherent in all spatial directions, and coherency filtering the second source coherency sorted signals.

Systems and methods are disclosed that facilitate central processing unit (CPU) throttling utilizing processes to facilitate enhanced management of CPU resources and to mitigate system crashes. A process (or group thereof) that occupies CPU resources at a percentage greater than a selectable predetermined threshold percentage can be monitored, suspended for a variable time period, and resumed. The process can be monitored to determine whether suspension of the process successfully reduced the percentage of CPU resources occupied by the process. Feedback information can be generated to facilitate a determination regarding a most suitable increase or decrease to suspension time of the process in order to minimize the number of reiterations required to successfully throttle the process. The invention also provides for an Ignore functionality, via which a process (or group thereof) can be exempted from throttling based on an exemption of the process, group of processes, and/or user.

A fully automatic and energy efficient lighting control or light switch comprises different settings, preset by a user, and activates all or a portion of at least one bank of lights upon detecting occupants within a room. In one embodiment, the light switch detects doppler-shifted, reflected ultrasonic waves caused by occupant motion within the room. In an automatic mode, the light switch is configured to automatically switch from an initial sensitivity level for detecting motion within a short range therefrom, to a higher sensitivity level for detecting motion anywhere within the room. After the room is empty or no motion is sensed, the light switch is configured to turn the lights off following a variable time delay. The light switch returns to its initial low sensitivity level following a predetermined grace period which begins once the lights are turned off. The lights can be turned off manually when the light switch is in its automatic mode, in which case, the light switch continues to operate at the higher sensitivity level. When motion is no longer detected, and following the variable time delay and predetermined grace period, the switch automatically returns to an automatic "on" state. In an alternative manual mode, the light switch can be activated manually and deactivated both manually and automatically. In its manual mode, the light switch is configured to deactivate the lights upon sensing no motion and is configured to reactivate the lights automatically within the predetermined grace period upon sensing motion.
