Service delivery systems and methods are described. In one aspect, a service delivery system includes a set of tokens, a database, multiple terminals, and a service manager. Each of the tokens includes a respective token identifier. The database stores personal user profiles each of which is associated with a respective token identifier. The terminals are distributed about a selected locale. Each terminal has a reader that is operable to read token identifiers from tokens and a controller that is operable to transmit read token identifiers and context data identifying one or more conditions under which a token identifier is read through a network connection each time a token identifier is read. The service manager is connected to each of the terminals through a respective network connection and to the database. The service manager is operable to invoke one or more services in response to receipt of a token identifier from a transmitting terminal to collect data selected based at least in part upon context data received from the transmitting terminal.

A method and circuit are provided for synchronizing a first circuit and a second circuit. The first and second circuits are signaled to each generate respective waveform outputs. A phase difference is determined between the generated waveform output from the first and second circuits. A clock of the first circuit and/or second circuit is adjusted by an amount corresponding to the determined phase difference. In response to the phase difference being less than a threshold value, the first and second circuits are signaled to begin normal operation.

Lockstep synchronization and maintenance

A method for adjusting a clock for a jitter sensitive circuit begins by determining a low noise phase region of a primary clock. The method then continues by adjusting phase of an auxiliary clock such that a transition of the auxiliary clock falls within the low noise phase region of the primary clock to produce an adjusted auxiliary clock.

Access to data storage is described. A general-purpose processor and an auxiliary processing unit (APU) interface coupled to the general-purpose processor are provided. Data storage coupled to the general-purpose processor via the APU interface is provided for a fixed or low variable read latency access and a fixed write latency access to the data storage. A first instruction is passed to the general-purpose processor and to the APU interface. The first instruction is identified as part of a set of instructions accessible by the APU interface. The first instruction is used to write data into the data storage. A second instruction is passed to the general-purpose processor and to the APU interface. The second instruction is identified as part of the set of instructions accessible by the APU interface. The second instruction is used to read the data from the data storage, and the data is then output.

A method and apparatus to reduce the probability of programmable logic device (PLD) failure due to single event upset (SEU) of configuration memory. A first portion of configuration memory cells are initially programmed with configuration data, leaving a second portion of configuration memory cells that are un-programmed. The programmed and un-programmed configuration memory cells are grouped into voting groups, where each un-programmed configuration memory cell of each voting group is programmed with the identical configuration data as contained within the originally programmed configuration memory cell of each voting group. The logic values of each configuration memory cell of each voting group are monitored by voting circuits, which enforce a triple modular redundancy (TMR) validation policy. The logical validation results are then applied to control points to mitigate PLD configuration memory errors caused by anomalous events such as neutron induced SEUs.

An apparatus and method for the automatic positioning of information access points. An electronically connected individual (ECI) passes within range of a first information access point (IAP) and obtains location information. Subsequently, the ECI passes within range of a second IAP which hitherto does not have any location information. The location for this second IAP can be estimated based on the location obtained from the first IAP, elapsed time, and the individual's estimated velocity vector. As the ECI passes by a third IAP, the location, elapsed time, and estimated velocity vector data corresponding to the third IAP can be used to refine the location of the second IAP. Over time, the location of the second IAP can be successively refined as ECI's move between IAP's.

A phone-enabled Internet access system is described. The access system includes an Internet-enabled rendering system coupled to an external Internet to render web pages received via the Internet. The access system also includes a dial-up server coupled to the Internet and a telephone network to receive a voice signal from a remote telephone via the telephone network. The voice signal contains a first web address indicating a desired web page and a second web address indicating the Internet-enabled rendering system on which the desired web page is to be rendered. The dial-up server extracts the web addresses from the voice signal and causes the desired web page to be retrieved from a remote web site to the rendering system via the external Internet for rendering. A phone-enabled Internet access gateway system is also described.

A system of networked terminal apparatus for creating a three dimensional animated work environment wherein terminal users of various levels of immersion are depicted as avatars in the virtual work environment and wherein actions and information of the terminal users is input into the virtual work environment through their corresponding avatars in order to perform complimentary, independent and cooperative tasks in parallel to create simultaneous sets of solutions to problems relating to command, control, communications, cognition and intelligence. In a preferred embodiment, the virtual work environment emulates an actual military command post, with all of the instruments and familiar surroundings emulated in function if not in form. The terminal users of the environment (i.e., the commanders and staff) immerse in this environment via virtual reality displays (audio and video) and inputs (microphone, body encoders and pointing devices) connected to individual personal computers. The avatars are able to interact with one another in the virtual environment and they are able to select and manipulate functional objects displayed in the virtual work environment. Non-immersed terminal users provide raw data streams to the virtual environment. The non-immersed terminal users are displayed as seated avatars or selectable icons. The immersed users, through their avatars, may select the seated avatars or icons to display data streams prepared by the non-immersed terminal users on projection screens displayed in the virtual work environment. The displayed data may be further processed by the immersed terminal users for collaborative decision making by the avatars present in the virtual environment. The processed data may be transmitted outside the virtual work environment as orders or instructions.

A system, method, and apparatus for displaying map information in a cardinal direction-up setting. In one embodiment, map information is displayed on a display terminal. Next, an icon representing the position and heading of an item with respect to the displayed map information is placed over the displayed map information. In the present invention, the map information is displayed in a cardinal direction-up setting corresponding to the heading of the icon. Thus, if the heading of the icon is directed in a substantially eastern direction, the map information is displayed in an east-up orientation. The present invention further includes hysteresis logic which regulates when a different cardinal direction is oriented upward.

A Personal Digital Location Apparatus for displaying a geographical location as an icon on a map. The apparatus includes a GPS Smart Antenna for determining the geographical location, a personal computing device including a display, a processing system including a standard software operating system such as DOS, Windows, Macintosh, or Geoworks, and a map application program capable of running in the operating system. The GPS Smart Antenna includes an internal battery and a power sensor for sensing the connection of an external power source. The GPS Smart Antenna receives power from the external power source when the power sensor senses that the external power source is connected and receives power from the internal battery when the power sensor senses that the external power source is not connected. An input select switch controlled by a Request to Send signal from the personal computing device enables the GPS Smart Antenna to use a single UART chip for receiving a command/control signal from the personal computing device and a differential GPS (DGPS) signal from a DGPS radiowave receiver.

Apparatus for visually displaying simultaneously on one screen two variables that characterize the path followed by a land, marine or airborne vessel with reference to a preselected or ideal path that extends from a beginning point to an ending point. Using two distinguishable icons or other indicia for the two variables, the screen displays a single one-dimensional scale and displays the two indicia, each of which represents one of the following differences: (1) the difference between at least one of the two horizontal location coordinates for the present vessel location and for a nearest point on the preselected path; (2) the difference between the elevation coordinates for the present vessel location and for a nearest point on the preselected path; (3) the difference between the present horizontal bearing angle of the vessel path and the horizontal bearing angle along the preselected path at a nearest point on the preselected path; and (4) the difference between the present vertical bearing angle of the vessel path and the vertical bearing angle along the preselected path at a nearest point on the preselected path. Alternatively, the screen may display two one-dimensional scales with either two indicia, three indicia or two mutually exclusive sets of two indicia. Alternatively, two indicia may be used to define the size of a rectangle and the quadrant it appears in, for representation of the two indicia.
