摘要： A system and method for tracking or otherwise determining positioning of an intracorporeal device is provided. The invention includes a device that may be inserted into a subject and tracked based on an imageable tag included with the device. The imageable tag is at least partially formed of a substance whose nuclei precess at a Larmor frequency different than the Larmor frequency of hydrogen when subjected to a polarizing magnetic field. MR data may be acquired from the imageable tag using an RF receiver tuned to the Larmor frequency of the substance and used to track movement of the device within the subject.

摘要： To improve the measurement accuracy of an air analyzer, a method of introducing position information to group and average a set of position-dependent air quality samples is proposed. The method comprises the steps of sampling the air at a first sampling rate to obtain a plurality of air quality samples by using a first sensor; sampling the positions of an apparatus at a second sampling rate to obtain a plurality of position samples; analyzing the plurality of position samples to obtain a plurality of spatial relationship information; grouping the plurality of air quality samples into a second plurality of air quality sample sets; and for each air quality sample set, calculating a representative value as the air quality value of a corresponding sampling duration. By using this method, non-position-relevant air quality samples can be excluded from the calculation of the air quality of a specific position or area.

摘要： The present invention proposes a wireless control system and method which may be mainly used in illumination networks. The wireless control system and method of the invention distributes data signals to be transmitted at a control terminal in different time slots of different frequencies for transmission, while each node in the system will only receive its corresponding data signal in a predetermined time slot of a predetermined frequency. Thus a high operating rate can be obtained at the control terminal while maintaining the operating rate of the node unchanged. This helps to greatly reduce the cost of the wireless transceiver of each node, thereby correspondingly reducing the cost of the whole system and realizing a high expansibility.
