  • 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.

  • Publication number: 20160198583
    Abstract: An AC to DC power adapter with an AC output has an AC output terminal serving to supply AC power to other equipment and connect to a peering AC to DC power adapter, such that multiple AC to DC power adapters can be connected in series with each other. Because all the AC to DC power adapters for installation at a site can be fully reused and no additional power adapters need to be purchased, material cost can be reduced. Also because the AC to DC power adapters can be relocated and reoriented and are sequentially connected with each other without having to concern locations of the fixed wall outlets to be connected, installation convenience can be ensured.

  • Patent number: 9355042
    Abstract: Method and apparatus for managing a translation lookaside buffer (TLB) at hardware in a virtualization enabled system. According to embodiments of the present invention, a series of operations caused by TLB miss would not need intervening from the hypervisor. On the contrary, when a TLB miss occurs, the hardware directly issues an interrupt to a virtual machine. In this way, the TLB can be efficiently managed by means of a hardware-level auxiliary translation table. Therefore, system overheads can be greatly reduced and system performance can be improved. Methods and apparatuses associated with hardware, hypervisor, and virtual machine in a virtualization enabled system are disclosed, respectively.
