A method of providing precise common timing in a wireless communications network including at least one timing marker unit with a precise common time source, e.g., GPS. Wireless mobile units and/or timing marker units periodically measure transmission timing differences between pairs of neighboring base stations and each provide the measurements to a base station or central network entity. Timing marker units measure timing associations and return the results. An absolute transmission timing difference (ATD) is determined for each base station timing difference measurement. ATDs are collected and combined for each pair of base stations. A timing relationship is developed for all base stations from the combined ATDs, relating transmission timing of non-reference base stations to reference base stations. Timing associations are extracted for non-reference base stations from these timing difference relationships and the timing associations for the reference base stations.

An electronically generated simultaneous display of the local time within multiple time zones in the world is adjusted to accommodate local time arising from Daylight Saving Time. A preferred modified south polar projection of the Earth which schematically depicts the Northern Hemisphere is divided into geographical time zones. Each geographic time zone is associated with a time marker that points to an adjacent time scale. Either the geographical time zones or the time markers are adjusted in order to correctly display the ongoing time changes resulting from the continuous observation of Daylight Saving Time in time zones of the world. As further features, a user may adjust the display to present a hypothetical time and the corresponding times experienced in different time zones around the world. A user may have a specific time zone highlighted by invoking data, such as a city name, a telephone area code or an address book contact reference, which is associated with specific time zone. Conversely, highlighting a time zone may invoke a list of data associated with that time zone, e.g. city names, countries.

A vehicle-mounted subsystem of the wireless signal system is internally provided with two train signal wireless transceiving devices, namely a maneuvering desk wireless transceiver and a tailstock wireless transceiver; the tailstock wireless transceiver is used for sending local train encrypted response information and local train basic marker data to a rearward train in real time; and the maneuvering desk wireless transceiver is used for detecting and receiving the encrypted response information sent out by the tailstock wireless transceiver of a forward train of a same direction and a same station track in real time, performing interactive recognition on the received encrypted response information and the local train encrypted response information, sending out the local train encrypted response information to the forward train, sending signals on the received encrypted response information to a local train control computer used for sending out an instruction on deceleration or braking, and receiving the basic marker data emitted by the tailstock wireless transceiver of the forward train, and the local train control computer is used for processing GPS (Global Position System) positioning information differential value of synchronous time-markers of two trains and calculating a distance between the forward train and the rearward train, so that the speed of the local train is controlled.

A system to determine position, frequency and clock offsets over a network utilizing signals of opportunity transmitted by one or more transmitters with known locations, the system includes a base receiver with a clock and a known position that determines ranges to the transmitters, takes a series of samples of the signals of opportunity and time tags the series with times of receipt, calculated times of transmission based on the calculated ranges, or both. The base receiver transmits the time tagged series and, as appropriate, computed ranges to the remote receivers. A given remote receiver saves and time tags samples of the signals of opportunity, correlates the time-tagged series with the saved samples, and calculates a time offset as a time difference of the times of receipt at the remote receiver and either the time of receipt at the base receiver or the time of transmission calculated at the base receiver. The remote receiver calculates position based on the time offsets, and as appropriate, the ranges provided by the base receiver. The elevations of the remote receivers may be calculated as part of the position calculations, determined iteratively based on constraining the Z coordinate to an average elevation, or determined from differences in air pressure sensor readings at the base and remoter receivers.

A method and apparatus for temporal tagging of videos in response to identification of locations on the video where persons in a contact list of a user are identified in response to facial recognition. The temporal tags can be retained within the video, or contained separately in a metadata file having fields to indicate time locations in the video and identified persons seen at those locations. Use of the temporal tags allows for automatic distribution of content relevant to the recipient, based on their presence in the video, or of persons in the video of which they are interested.

A page of non-volatile multi-level storage elements on a word line WLn is sensed in parallel while compensating for perturbations from a neighboring page on an adjacent word line WLn+1. First, the programmed thresholds of storage elements on WLn+1 are sensed in the time domain and encoded as time markers. This is accomplished by a scanning sense voltage increasing with time. The time marker of a storage element indicates the time the storage element starts to conduct or equivalently when the scanning sense voltage has reached the threshold of the storage element. Secondly, the page on WLn is sensed while the same scanning voltage with an offset level is applied to WLn+1 as compensation. In particular, a storage element on WLn will be sensed at a time indicated by the time marker of an adjacent storage element on WLn+1, the time when the offset scanning voltage develops an appropriate compensating bias voltage on WLn+1.

A process for producing a recorded version of proceedings that is aligned with a textual transcription of the same proceedings. The process using an audio recording of the proceedings matches words recognized by a speech-recognition program with words in the textual transcription file. Each word of the textual transcription, is marked with the time at which the corresponding word occurred in the recording. The transcribed recording and transcription file are sent in a series of sequences from one or more user stations. The server distributes the word matching and word timing tasks to one of a number of workstations before returning the time marked transcription file to the user stations. The process is particularly useful in preparing and presenting recordings of witness' depositions and other legal proceedings.

  • a step of determining a first flight plan portion comprising the definition of a lateral offset angle from the original flight plan;
  • a step of determining a vertical descent profile;
