  • Patent number: 10841061
    Abstract: An apparatus for wireless communication includes a classification unit and an allocation unit. The classification unit classifies communication devices in a cell where the apparatus is located, the communication devices are classified into a plurality of communication device groups including a first communication device group and a second communication device group. The allocation unit allocates pilot frequency sequences in a first pilot frequency group to the first communication device group, and allocates pilot frequency sequences in a second pilot frequency group to the second communication device group. When the number of the pilot frequency sequences is insufficient, a multiplexing configuration is executed, such as communication devices in the second communication device group multiplex at least one pilot frequency sequence in the second pilot frequency group.

  • Patent number: 10723029
    Abstract: The present invention discloses a safety protection method of dynamic detection for mobile robots. The mobile robot is provided with a sensor. Said sensor obtains the obstacle information in the detection areas in front of a mobile robot, and the mobile robot is caused to progressively slow down and dynamically adjust the detection area when an obstacle appears in the detection area. If no obstacle is detected in the detection area after adjusting, then the mobile robot is caused to keep on moving, and if an obstacle is still detected in the detection area after adjusting, then the mobile robot is caused to keep on decelerating until they are stopped. The sensor sets different detection areas according to the traveling speed and traveling direction of the mobile robot, or presets the detection area according to the path and dynamically adjusts it when the mobile robot is running.

  • Patent number: 10705061
    Abstract: A rapid flow-through, highly sensitive microfluidic photoionization detector (PID) which is micro-fabricated directly onto a substrate, such as a conductive silicon wafer, is provided. The microfluidic PID has an ionization chamber volume of less than 9 ?L. The microfluidic PID may have a flow through design with a microfluidic channel defines a serpentine pattern on the substrate. The flow through design of the microfluidic PID results in negligible dead volume, thus allowing a shortened response time over existing commercially available designs. Such microfluidic PIDs are particularly useful with gas chromatography (GC), including microGC and multi-dimensional microGC systems. Methods for calibrating PIDs are also provided.
