摘要： The present invention provides a Positioning on One Device (POD) for locating and tracking objects and an autonomous ultrasound indoor track system (AUITS) and method for locating objects by using the POD. The AUITS can comprise: a tag device installed on a mobile object, which includes radio frequency (RF) and ultrasound transmitters for transmitting RF and ultrasound signals; and a POD for receiving the RF and ultrasound signals transmitted from the tag device to locate the mobile object. The POD can comprise: a plurality of leaf modules, each of the leaf modules including a positioning signal receiver for receiving the positioning signals (e.g. ultrasound signal) transmitted from the tag device, wherein there is a known structural topology relationship between the plurality of leaf modules. Then, the positioning signal detection times from respective positioning signal receivers and the structural topology relationship of the POD can be used for calculation of the position of the object. Compared with the prior arts, the POD and the AUITS system of the present invention presents several advantages, such as high accuracy, easy deployment, calibration free, low cost, in-device coordination, and flexibility.

摘要： A pattern of conductive micro-wires as in a conductive pattern can be prepared using photo-lithography, or imprint technology. A photocurable composition is cured to form a pattern of photocured micro-channels. A conductive composition comprising metal nano-particles is added to the photocured micro-channels and excess conductive composition outside the photocured micro-channels is removed. The conductive composition in the photocured micro-channels is then dried at a temperature of less than 60° C. The dried conductive composition in the photocured micro-channels is treated with hydrogen chloride vapor to form conductive micro-wires in the photocured micro-channels at a temperature of less than 60° C. The outer surface of the conductive micro-wires is then polished in the presence of water, to form a micro-wire pattern.
