Abstract: A system includes a first cavity with an open upper proximal end and a distal end including a plurality of ports. A second cavity can be concentric with and advanceable through the open upper proximal end of the first cavity. The second cavity can include an open upper proximal end. A plunger can be on a distal end of the second cavity. The plunger can be configured to move a first constituent from the first cavity through at least one of the plurality of ports. A plunger rod can be advanceable through the open upper proximal end of the second cavity and configured to move a second constituent from the first cavity through at least one of the plurality of ports.

Abstract: During operation, an access point may provide a first WLAN and a second WLAN, where the first WLAN uses a WPA2-compatible authentication protocol and the second WLAN uses a WPA3-compatible authentication protocol. In response to an association request or a probe request associated with (or from) an electronic device, the access point may establish a connection with the electronic device using the first WLAN. Then, the access point may confirm, with a computer system, that a binding between a passphrase associated with the electronic device and the second WLAN exists. Alternatively, when the binding does not exist, the access point may establish the binding in the computer system. Next, the access point may perform a BSS transition of the electronic device from the first WLAN to the second WLAN.

Abstract: The present disclosure relates to a short-range communication device (10, 10?, 5 10?) for a personal protective equipment or a personal protective device (200, 210, 220, 230) comprising a transmission unit (20, 20?, 20?) for wirelessly transmitting a voice signal of a user (100, 110, 120, 130, 140, 150, 160) to a receiving unit (40,40?, 40?) over a predetermined distance such that a communication channel is established between the transmission unit (20, 20?, 20?) and the receiving unit (40, 40?, 40?) so that a user (100, 10 110, 120, 130, 140, 150, 160) can hear the voice signal. The present disclosure further relates to a short-range communication system comprising at least two short-range communication devices (10, 10?, 10?) according to the present disclosure and to a method of establishing a short-range communication between such devices (10, 10?, 10?).

Abstract: Provided are devices, methods, and systems for generating and deploying networking profiles for enabling computing devices to connect to wireless networks in a secure manner. For example, a method may include: receiving a request for a networking profile from a second computing device, the networking profile configured to enable the second computing device to access to a wireless network; generating, based on the received request for the networking profile, a code for presentation; transmitting the code for presentation to the second computing device; receiving an indication of a content of the code for presentation from a first computing device different than the second computing device; generating the networking profile based on receiving the indication of the content of the code for presentation; and transmitting the generated networking profile to the second computing device.

Abstract: During operation, a computer network device may provide an identifier for a network (such as an SSID for a WLAN) that supports certificate-based authentication and pre-shared-key-based authentication. Then, during an authentication procedure, the computer network device may receive an authentication request associated with an electronic device, where the authentication request specifies an instance of the certificate-based authentication or an instance of the pre-shared-key-based authentication. Moreover, the computer network device may provide authentication information addressed to a computer based at least in part on the authentication request.

Abstract: An electronic device that selectively provides secure access of a second electronic device to a network is described. This electronic device receives an access request associated with a computer, where the access request includes one or more authentication parameters associated with a user. In response, the electronic device confirms the one or more authentication parameters to determine whether there is an authentication match. Moreover, when there is an authentication match, the electronic device accesses a policy associated with or that includes: a spatial criterion, a temporal criterion, information associated with the user, information associated with the one or more authentication parameters, and/or information associated with the network.
