Abstract: A detection system and method for the migrating cell is provided. The system is configured to detect a migrating cell combined with an immunomagnetic bead. The system includes a platform, a microchannel, a magnetic field source, a coherent light source and an optical sensing module. The microchannel is configured to allow the migrating cell to flow in it along a flow direction. The magnetic field source is configured to provide magnetic force to the migrating cell combined with the immunomagnetic bead. The magnetic force includes at least one magnetic force component and the magnetic force component is opposite to the flow direction of the microchannel. The coherent light source is configured to provide the microchannel with the coherent light. The optical sensing module is configured to receive the interference light caused by the coherent light being reflected by the sample inside the microchannel.

Abstract: A method for calibrating a depth of a 3D camera includes selecting a calibration plane and obtaining a first depth image of the calibration plane using a 3D camera when a distance between the 3D camera and a calibration plane is a standard distance. A first depth image, represented by a first phase values of pixel points, is obtained. Then obtaining a second depth image of the calibration plane using the 3D camera when a distance is a testing distance, and intercepting the phase values of the pixel points of the two-dimensional image region and deleting the phase values of the pixel points of the non two-dimensional image region in the second depth image. Calculating and outputting predicted phase values of pixel points in the non two-dimensional image region of the second depth image and calibrating the second depth image.

Abstract: A mobile communications device accompanying with a radio frequency (RF) unit is provided for roaming Public Land Mobile Network (PLMN) selection. In the mobile communications device, a processing unit directs the RF unit to register to a plurality of PLMNs one at a time for reception of at least one Short Message Service (SMS) text message from the currently registered PLMN, and then retrieves service charging information from the SMS text message for each of the PLMNs. Also, the processing unit directs the RF unit to register to one of the PLMNs for obtaining mobile services therefrom according to the service charging information.
