  • Publication number: 20240115410
    Abstract: An assistive device structure for positioning and pressure relief is provided, including a first elastic layer and a second elastic layer, which are attached by using a high-frequency encapsulation process, sealing, bagging, thermoforming, or an integrally molding process. Each of the first and second elastic layers has a bottom surface and an arc surface disposed opposite to each other. The arc surface includes two protrusions and a recess formed there in between. The two protrusions have different heights. A hollow area is disposed in the recess of the first and second elastic layers. Based on such structure, the bottom surfaces of the first and second elastic layers are attached to form the proposed assistive device structure for a user to lean against and providing multiple positioning effects and pressure relief. More than four axial directions of supporting forces are generated to effectively enhance muscle relaxation and stress relief.

  • Publication number: 20160065464
    Abstract: A modem capable of distributing IPv6 addresses upon request is connected to a user terminal. The user terminal requests and receives multiple IPv6 addresses from the modem, the IPv6 addresses including quality of service values corresponding to different priorities. The user terminal determines a range of quality of service required according to a priority of the message to be sent, and selects an IPv6 address with a quality of service value belonging to the determined range to send the message.

  • Patent number: 8902555
    Abstract: A smart alarm plug, socket, wall-mounted socket or connector includes a casing, a normally-open temperature control switch, a normally-closed temperature control switch and an alarm device. The casing is provided with a live wire pin, a neutral wire pin, an earth wire pin, and connecting core wires. The heat resistance value of the normally-closed temperature control switch is greater than the heat resistance value of the normally-open temperature control switch. When the temperature of the power wire is abnormal, the normally-open temperature control switch will be closed for the alarm device to connect with the power, such that the alarm device sends an alarm signal to warn the user to examine the circuit, providing a warning effect. When the temperature is over the preset value, the normally-closed temperature control switch will be opened to cut off power supply, achieving a fire alarm effect.

  • Patent number: 8774095
    Abstract: A wireless access point device receives a packet including a first source port number from a source wireless terminal device, determines if the packet is a control packet according to the first source port number, and obtains a time interval and a second source port number from the control packet and to receive a new packet. The wireless access point device further determines if the new packet is the data packet according to whether the first source port number of the new packet is the same as the second source port number, starts a timer to time for the time interval once the new packet is the data packet, and transmits a Clear-to-Sent packet to other wireless terminal devices once the timer times out.

  • Patent number: 8522336
    Abstract: A gateway device that is in electronic connection with at least one client computer, a first domain name system (DNS) server located in a first communication network, and a second DNS server located in a second communication network separated from the first communication network. When a domain name is transmitted to both the first DNS server and the second DNS server, the first DNS server and the second DNS server respectively resolve the domain name into two groups of internet protocol (IP) addresses, and the gateway device compares the two groups of IP addresses with each other to select one of the two groups of IP addresses that is identified as all IP addresses of which are safe, and allows the client computer to access websites within the first communication network via the selected group of IP addresses to prevent the client computer from phishing attacks.
