摘要:
A method and apparatus are disclosed for determining more accurately, in a radio environment with time dispersion, the distance between a radio receiver and radio transmitter, by special processing of received radio signals that have been transmitted repeatedly from the same radio transmitter and are possibly subject to multipath propagation. The Time of Arrival (TOA) of the received radio signals is repeatedly estimated using channel power profiles. A TOA value near the minimum occurring TOA is selected wherein each estimated TOA is derived from incoherent integration of a randomly chosen number of the received bursts having the same known bit sequence, in order to eliminate the influence of noise.

In a particular embodiment, a method includes receiving a first set and a second set of location data at a mobile device. The method includes locating a first reference point identifier that is included in the first set of location data and a second reference point identifier that is included in the second set of location data. The first reference point identifier field and the second reference point identifier field identify a common reference point. The method includes identifying first information in the first set of location data that is associated with the common reference point. The method also includes identifying second information in the second set of location data that is associated with the common reference point and spatially aligning the first set of location data with the second set of location data based on the common reference point to associate the first information with the second information.

Various techniques are provided for Location Services (LCS) Assistance Data broadcast, for example for implementation in LTE and LTE-A systems. The embodiments described herein may use the LPP/LPPe positioning protocol, by making use of existing unsolicited Provide Assistance Data (PAD) messages. Embodiments avoid the need to define and implement a separate broadcast Assistance Data protocol. Additional exemplary embodiments for scheduling and verifying of the broadcast Assistance Data messages are described herein.

摘要:
Positions of non-reference wireless transceivers to be added to a wireless communication network are determined as follows. Each non-reference wireless transceiver performs measurements of times of arrival (TOA) of signals transmitted by other non-reference wireless transceivers, as well as reference wireless transceivers. Thereafter, time difference of arrival (TDOA) values are computed from at least two types of pairs of measurements as follows: (a) unknown-unknown TDOA values are obtained as differences between TOA measurements of signals transmitted by non-reference wireless transceivers and (b) unknown-known TDOA values are obtained as differences between a TOA measurement of a signal transmitted by a non-reference wireless transceiver and another TOA measurement of another signal transmitted by a reference wireless transceiver. Both types of TDOA values are used to solve simultaneous equations to identify the positions of the non-reference wireless transceivers and optionally times of transmission of the signals by the non-reference wireless transceivers.

The invention relates to a device and a method for producing containers, such as e.g. bottles, in which different types of bottles are produced. Alternative treatment methods are used depending on the type of bottle to be produced. For example, a cooling treatment is carried out when producing bottles for carbonated beverages and a sterilisation treatment is carried out when producing bottles for non-carbonated beverages.

Each of a first and a second navigation satellite system (NSS) are adapted to operate according to a first and a second specification, respectively, and each includes a first and a second plurality of space vehicles (SV), respectively. Each of the first and the second plurality of SVs are adapted to be identified by a first and a second plurality of unique corresponding identifications (IDs), respectively. A processor is adapted to receive and identify a first plurality of corresponding signals transmitted from the first plurality of SVs in response to the first plurality of unique corresponding IDs. The processor is adapted to receive and identify a second plurality of corresponding signals transmitted from the second plurality of SVs in response to the second plurality of unique corresponding IDs. The processor is adapted to determine position location information in response to receiving and identifying the first plurality of corresponding signals and the second plurality of corresponding signals.
摘要:
There is described a process for the cleaning of an installation, whereby the installation is rinsed with an alkaline cleaning solution and the result of the cleaning is tested by means of an indicator agent on the basis of permanganate in an alkaline environment. In order to make the cleaning more economical and less productive of waste water, it is proposed to introduce the indicator agent that is used as an indicator into the alkaline cleaning solution for further use as a cleaning agent.
