A plurality of resources, typically service operatives, are allocated to a plurality of tasks by a method in which initial information relating to the tasks to be allocated and the resources available to perform the tasks is provided. An initial series of schedules is first generated allocating resources to the tasks, and then modifying the individual schedule of at least one resource in response to updated information. Changes to individual schedules may be made in response to such updated information independently of the schedule generation. The initial, series of schedules may be generated in a two-stage process in which a rule-based system allocates tasks selected as being difficult to allocate (e.g., because they are linked to other tasks). then a stochastic (non-systematic) search system compiles the rest of the schedule. Periodically, the stochastic system may be interrupted to allow a further rule-based system to analyze the schedules created thus far, and fix the best ones in the schedule, so that the stochastic system can then concentrate on improving the remaining schedules. In order to allow the system to handle rapid changes in the requirements for tasks and the resources, on a scale faster than the time required to generate the schedules, a schedule modification system is arranged to make changes in the short term in between schedule updates delivered by the schedule generation system.

Device, system and method, in a vehicle communication system, to transmit wirelessly a message comprising the position, heading and speed of a vehicle or other moving object, wherein the transmission is repeated at regular intervals in a temporarily fixed time slot within a predetermined basic time interval. In a key embodiment the message duration is equal to or less than a predetermined time slot duration. Embodiments use generally the same time slot in a contiguous sequence of basic time intervals. Algorithms are described to resolve wireless interference within a time slot. Embodiments divide the basic time interval in multiple durations, “class regions,” for different message classes. Embodiments use different wireless bandwidth allocation algorithms for the class regions.

The disclosure describes systems for creating and authenticating printed objects using authentication information. Techniques for incorporating authentication information into digital representations of objects and using the authentication information to authenticate the objects are also provided.

The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.

A method for incorporating one-time-tokens, coupon and reward systems in conjunction with merchants' POS checkout systems in the physical or virtual environments includes providing a consumer computing device comprising an electronic wallet application, providing a One-time Token Redemption System(OTRS) and user electronic wallet accounts, logging into a user electronic wallet account through the electronic wallet application, sending a request for a one-time token valid for a specified time interval and then forwarding the request for the one-time token to the OTRS and upon approval sending the requested one-time token from the OTRS to the electronic wallet application. Next, presenting and entering the one-time token into a merchant point of sale checkout system within the specified time interval via the consumer computing device, sending the entered one-time token to a checkout application, and then processing payment via a secure payment application.

A device for use in, and system for, a vehicle-to-vehicle (V2V) communication and safety system that uses a hybrid combination of TDMA and CSMA protocols. The synchronized TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. The TDMA portions of a repeating time interval uses self-assigned dense time slots for high-priority safety messages, with one portion for emergency vehicles and road-side units. The CSMA protocol uses remaining available time for lower-priority and overflow messages. The higher-priority time interval classes change size dynamically based on the number of current transmissions. Modulation schemes, but not data link formats, use existing Standards. Embodiments include optimized traffic flow and signal timing.

Device, system and method, in a vehicle communication system, of transmitting a risk value in a message, wherein the risk value identifies quantitatively a risk of vehicle collision.

Embodiments include driver warnings responsive to the risk value in a received message. Embodiments include a collision type in a message. Embodiments include unique features of: risk is applicable to receiving vehicles; risk is applicable to a geographical region; computation and storage of location histories; messages free of IP and MAC addresses; haptic devices used for driver warning.

A transceiver in a vehicle-to-vehicle (V2V) communication and safety system that regularly broadcasts safety messages, comprising location, heading and speed, of a subject vehicle, that are free of MAC and IP addresses. The V2V system uses the location of the subject vehicle for vehicle identification, in place of a pre-assigned vehicle ID. Some embodiments broadcast safety message in self-assigned time slots in a synchronized TDMA broadcast architecture, with unusually short inter-message gaps and unusually short messages. The TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. Time slot selection uses weighted algorithms. Selected time slots are held until either a message collision or a timeout occurs. A transceiver equipped vehicle may proxy a different subject vehicle. Embodiments include optimized traffic flow and signal timing.

A data processing apparatus and method are provided for managing cache coherency. The data processing apparatus comprises a plurality of processing units, each having a cache associated therewith, and each cache having indication circuitry containing segment filtering data. The indication circuitry is responsive to an address portion of an address specified by an access request from an associated processing unit to reference the segment filtering data in order to provide, for each of at least a subset of the segments of the associated cache, an indication as to whether the data is either definitely not stored in that segment or is potentially stored in that segment. Further, in accordance with the present invention, cache coherency circuitry is provided which employs a cache coherency protocol to ensure data accessed by each processing unit is up-to-date. The cache coherency circuitry has snoop indication circuitry associated therewith whose content is derived from the segment filtering data of each indication circuitry. For certain access requests, the cache coherency circuitry initiates a coherency operation during which the snoop indication circuitry is referenced to determine whether any of the caches require subjecting to a snoop operation. For each cache for which it is determined a snoop operation should be performed, the cache coherency circuitry is arranged to issue a notification to that cache identifying the snoop operation to be performed. By taking advantage of information already provided in association with each cache in order to form the content of the snoop indication circuitry, significant hardware cost savings are achieved when compared with prior art techniques. Further, through use of such an approach, it is possible in embodiments of the present invention to identify the snoop operation not only on a cache-by-cache basis, but also for a particular cache to identify which segments of that cache should be subjected to the snoop operation.
