摘要:
The invention is directed to a method of synchronizing transmission between two nodes in a wireless network. The method comprises the steps of obtaining an expected interference profile for each node; and agreeing a synchronized transmission schedule between the nodes, where the expected interference profile of the or each node meets predetermined criteria.

The present invention presents a method, arrangement and computer program product for clocking exploiting the relative behavior of clocks of individual receiving stations as well as a corresponding modeling to derive a time difference of arrival of a signal from a user device which can be used to correct the time difference of arrival based on the modeled clock behavior and leads to a correct clocking of received user signals without the need of synchronization of the clocks in the various receiving stations. This principle is applicable to a plurality of pairs of receiving stations and beacon signals transmitted amongst them and allows for a correct location estimation of a user device.
摘要:
An apparatus for storing and dispensing of a plurality of items of stock (34) such as pharmaceuticals comprises a plurality of storage regions (20), e.g. shelves (26) and a dispensing station (48). The storage regions (20) are arranged to circulate around a continuous path (10) such that each storage region (20) is periodically brought into alignment with the dispensing station (48) so as to allow items to be removed from the storage region (20) at the dispensing station (48).
摘要:
An automated pharmaceutical dispensing system comprises a retrieval subsystem (4) for selecting and retrieving a pharmaceutical pack (38). The retrieval subsystem (4) is arranged to deliver the pack (38) to a labelling station (6). The labelling station (6) comprises a label printer (18) arranged to print a label (36) comprising information specific to a patient for whom said pharmaceutical pack (38) is intended and a label applicator subsystem (22) for applying the label (36) to the pack (38). The system further comprises a delivery subsystem (8) for delivering the pack from the labelling station to a user-accessible point. The label applicator can apply the label (36) in a way determined by a dimension of the pack (38)—e.g. at a predetermined position, predetermined orientation or across two discrete planes of the pack (38).

The invention is directed to a method of synchronising transmission between two nodes in a wireless network. The method comprises the steps of obtaining an expected interference profile for each node; and agreeing a synchronised transmission schedule between the nodes, where the expected interference profile of the or each node meets predetermined criteria.

摘要:
The invention is directed to methods and apparatus for transmitting data between a first node and a second node in a communications network, for example a wireless network. The method comprises the steps of selecting a transmission channel from a predetermined set of transmission channels according to probability information and transmitting data using the selected channel. The probability information is based on a determination of a characteristic of previous transmissions using each of said set of channels. The invention is also directed to a method of selecting a channel at a node in a communications network for communication with a second node.

A vehicle and method for controlling an engine in a vehicle are provided. A temperature of a lubricating fluid in the engine is determined, as are first and second engine speed limits. Operation of the engine at the first engine speed limit is limited to a predetermined time period when the lubricating fluid temperature is between first and second predetermined temperatures. The engine speed is at least temporarily limited to the second engine speed limit after the engine has been operated at the first engine speed limit for the predetermined time period and the lubricating fluid temperature is between the first and second predetermined temperatures.
摘要:
A non-rotatable radar antenna installation for aircraft for providing 360.degree. azimuthal scanning, which includes a generally triangular radome carried by the aircraft, and three substantially planar radar antennas arranged in a triangular planform within the radome. 360.degree. azimuthal coverage is achieved by the sequential side-to-side scanning of the three antennas. The planform area of the triangular radome and consequently the drag and weight penalty of the radome upon the aircraft is substantially less than equivalent radar antenna installations of circular configuration.
