    • A pressurised medicament canister (4) has a valve (2) which dispenses a metered dose upon being released from a depressed condition. An inhaler device adapted for use with the canister has a breath-actuated latch mechanism (60, 62; 208, 216) arranged in use to latch the canister (4) in a depressed condition and further to release the latch (60, 62; 208, 216) in response to inhalation through the inhaler by a user. Also disclosed is a dose counter for counting the number of doses dispensed from the canister comprising a counter member (240) having a helical toothed track (238) which is incrementally advanced each time a dose is dispensed from the canister (4). Also disclosed is a valve for the canister comprising a sliding seal delimiting the metering chamber and slidable relative to a nozzle member, said sliding seal being biased in (136) use to reduce the volume of the metering chamber (146) substantially to zero once the metering chamber (146) has been vented to the atmosphere.

    • In a data processing method and apparatus, an image signal representative of features in a space of two or more dimensions is progressively filtered at monotonically increasing filtering scales, the signal being input to the first filtering scale, and the input to the or each subsequent filtering scale is the output signal from the previous scale. Each input has a number of data samples each of which represents a respective region of the space, and at each filtering scale those samples are sorted into connected-sets, each of which contains a plurality of substantially equal value to data samples or a respective individual data sample not in other sets. The process then selects those connected-sets which contain data samples having values which are local maxima or local minima and which represent a composite region of a size related in a predetermined way to the current filtering scale. Each selected set is then effectively merged with the adjacent connected-set which contains data samples of a value closest to that of the sample(s) in the selected connected-set. This is achieved by changing the latter's value to that of the samples in the adjacent connected-set. The output signal for the filtering method is derived from the output of at least one of the filtering scales. In at least one of those scales, both connected-sets having local maxima and connected-sets having local minima are selected, thereby increasing the tolerance of the method to noise.
    • 在数据处理方法和装置中,代表两维或更多维的空间中的特征的图像信号以单调增加的滤波比例逐渐过滤,该信号被输入到第一滤波标度,并且输入到每个后续滤波 scale是来自前一个比例的输出信号。 每个输入具有多个数据样本,每个数据样本表示空间的相应区域,并且在每个滤波标度下,这些采样被分类成连接组,每个连接组包含与数据样本或相应个体基本上相等的多个值 数据样本不在其他集合。 然后,该过程选择包含具有局部最大值或局部最小值的数据样本的那些连接集,并且其表示以预定方式与当前滤波标度相关联的大小的复合区域。 然后,每个所选择的集合被有效地与包含在所选择的连接集中的样本的值的最接近的数据样本的相邻连接集合合并。 这是通过将后者的值改为相邻连接组中的样本的值来实现的。 用于滤波方法的输出信号从至少一个滤波标度的输出导出。 在这些尺度中的至少一个尺度中,选择具有局部最大值的两个连接组和具有局部最小值的连接组,从而增加该方法对噪声的容限。

    • Apparatus for determining a displacement characteristic of an object comprises means (Tx1, Tx2, 3, 4) for transmitting, at a given transmission time, a probe signal towards the object; means (5, 6) for receiving the probe signal returned by the object; means (DL11, DL12, PG28, PG30) for generating a detection timing signal at a delay after the transmission time, corresponding to a selected range for the object; first detecting means (Rx7, Rx8), coupled to the receiving means and responsive to the timing signal, for detecting the returned probe signal occurring at the delay of the timing signal; and second detecting means (Rx19, Rx20) for detecting the relative timing of the detection timing signal and of a signal having a predetermined timing with respect to the transmission time; whereby a measure of the range of the object can be determined from the relative timing of these two signals, from which range measure the object displacement characteristic can be determined. Apparatus for transmitting and receiving data is also disclosed, as further is apparatus for assessing the approach of an object to a specified location. Analogous methods are also disclosed.
