  • Publication number: 20200168332
    Abstract: Provided herein is a display system for medical information and a method for generating display content. The system is applicable to a medical institution for monitoring statuses of patient beds. The system includes a patient bed system and a central serving system. The central serving system receives data generated by medical instruments around the patient beds simultaneously. In the central serving system, the data is analyzed and compared with thresholds for classifying the statuses of the patients. After visualizing the data, an information display panel is incorporated to display the information with respect to each of the patient beds. The status at each patient bed can be expressed by various graphic charts and shown on the panel. The different degrees of the statuses of patients are shown with different display effects that can be provided for the medical staff to determine and deal with emergency situations immediately.

  • Patent number: 10526838
    Abstract: The present invention provides a liquid drainage assembly for an automatic, roll-up door and has an attaching member connecting a drip tray to a surface proximate the door. The attaching member moves drip tray from a position where the tray is disposed under a bottom edge of the door to collect liquid flowing across the bottom edge when the door is in an open position to a position where the tray is outside the vertical plane in which the door moves to allow the door to move to a closed position. A motor moves the door in response to signals received from a controller which ensures coordinated movement of the door and the drip tray.

  • Patent number: 10082854
    Abstract: A network device that includes a power source device (PSE) circuit, a MOS switch, a network connector and a detection unit is provided. The network connector has a first and a second terminal electrically coupled to the voltage source and to the ground terminal through the MOS switch respectively. Under the condition that the PSE circuit is not activated, the detection unit detects a first non-zero voltage pulse at the second terminal to determine that a powered device is attached to the network connector to activate the PSE circuit to generate and transfer the power to the powered device through the network connector. Under the condition that the PSE circuit is activated, the detection unit detects a second non-zero voltage pulse at the second terminal to determine that the powered device is detached from the network connector to deactivate the PSE circuit to stop generating the power.
