摘要： A method and system for dynamically tracking the location of mobile nodes (104, 106, 108, 110n) in a wireless network (102) is disclosed. The method comprises: for each mobile node, dynamically measuring the range between the mobile node and at least one neighboring node (step 202); and executing a Bayesian tracking algorithm for each mobile node (step 204). The algorithm has the measured range as an input, exchanges data with tracking algorithms for neighboring mobile nodes, and utilizes a statistical model of error in measured range and a statistical model of node motion to dynamically determine location.

摘要： Disclosed is a method of measuring time of arrival of a signal transmitted from a transmitter (120) to reciever (110-n). The method comprises: modulating a plurality of narrowband signal portions onto different carrier frequencies; transmitting by the transmitter, each modulated signal portion to the receiver; receiving, by the receiver, the transmitted signal portions; estimating the channel impulse response by combining (610) the received signal portions; and measuring (620) the time of arrival using the estimated channel impulse response. Further disclosed is a method of measuring a time of arrival of a signal transmitted from a transmitter to a receiver. The method comprises: estimating a noise level (1310) in an impulse response of a channel between the transmitter and the receiver; finding a first peak (1330) in the channel impulse response that is not noise or a side lobe of a subsequent peak, using the estimated noise level; and measuring the time of arrival (1220) using the first peak.

摘要： A fluid dispensing device for dispensing a fluid form medicament formulation having a viscosity of from 10 to 2000 mPa·s. is disclosed and comprises a housing and a fluid discharge device. The fluid discharge device is arranged to be actuated by one or more levers so as to apply a force to the fluid discharge device which is used to move a container forming part of the fluid discharge device along a longitudinal axis of the fluid discharge device to cause actuation of a pump forming part of the fluid discharge device. A pre-load means is used to prevent actuation of the pump until a pre-determined force is applied to each lever of sufficient magnitude to guarantee the production of a well developed efficient spray from the fluid dispensing device.

摘要： There is disclosed a method and receiver for decoding a data signal from analogue signals received at one or more receiving antennas (24). The decoding is performed on the basis of bit value probabilities (66) derived from an effective signal to noise ratio (ESNR) (64) and a respective symbol error value (SEV) (62) calculated for all of the one or more receiving antennas. The ESNR is calculated utilising signal to noise ratios (SNRs) (58) per sub-channel and sub-channel transfer functions (60) measured for each of the one or more receiving antennas (24). Also, the SEVs are calculated utilising the measured sub-channel transfer functions.
