摘要： An inkjet ink composition comprising: (a) water; (b) dispersed pigment particles; and (c) at least one humectant; wherein the pigment particles are present from about 4.5% by mass to about 10% by mass, and the pigment particles have a mass weighted mean Stoke's diameter of from about 35 nm to about 70 nm wherein the Stoke's diameter is determined by differential centrifugal sedimentation of the particles through a fluid in a disc centrifuge. The present invention employs specified sedimentation particle sizing criteria for selection of appropriate pigment particle sizes at high pigment concentrations to obtain improved ink performance. Further embodiments of the invention also demonstrate that the criticality of humectant types and levels employed in an ink can also become much more important at high pigment loading in order to obtain desired performance.

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.
