Abstract: Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems implementing a one-touch login service are described. Information about a first IP address is obtained from a verification request sent by an application client device. A token is sent to the application client device. Information about a second IP address is obtained from a number acquisition request sent by an application server. Whether the first IP address is the same as the second IP address is determined. If the same, based on a token carried in the number acquisition request, a mobile phone number of a terminal device in which the application client device is located is obtained and the mobile phone number is sent to the application server. If not the same, sending the mobile phone number of the terminal device to the application server is refused.

Abstract: A computer-implemented method for communication channel management performed by a wireless access point (AP) device is described. An original management frame that carries a target information element is constructed, where the target information element includes an information element related to communication channel management. When determined that one or more clients are connected to the AP device, for each of the determined clients: A destination address of the original management frame is set to a MAC address of the client. To obtain an encrypted management frame by using a key corresponding to the client, information in the target information element is encrypted. The encrypted management frame is sent in a WiFi network, so that a connected client in the WiFi network determines, based on the destination address, whether to process the encrypted management frame.

Abstract: The present invention is directed to an apparatus and method of fabricating a sealed storage system for environmentally sensitive aqueous materials with liquid flow control and on-demand distribution. The present invention features a sealed storage apparatus capable of compactly containing a liquid reagent with liquid control capabilities. The apparatus may comprise a liquid-impermeable, air-impermeable, resistant to force-induced tearing pouch body capable of being penetrated through the application of a laser. The apparatus may further comprise a pouch cavity disposed within the pouch body for holding the liquid reagent. The apparatus may further comprise a liquid-impermeable, air-impermeable, and resistant to force-induced tearing sealing adhesive disposed over the pouch cavity to seal the liquid reagent within the pouch body capable of being penetrated through the application of the laser.

Abstract: The present invention is directed to a recirculation system for use in microfluidic centrifugal disc platforms for reusing and mixing an entire sample. The present invention features a system comprising a reservoir, an input channel, a detection array, a pressure chamber, and a recirculation channel connecting the pressure chamber to the reservoir. The recirculation channel may have a resistance lower than the channel upstream resistance. When the CD platform spins at a high RPM, the liquid may be directed from the reservoir into the pressure chamber. When the RPM of the CD platform decreases rapidly, the liquid may be from the pressure chamber through the channel and through the recirculation channel to the reservoir, such that the liquid travels through the recirculation channel faster than the liquid travels through the channel.
