  • Publication number: 20240298216
    Abstract: Disclosed herein are systems, methods, and computer-readable media for minimizing pre-roaming resource reservations. In one aspect, it is determined that a client device connected to a first Access Point (AP) will roam, based on the determination, generating a list of APs that are roam candidates supportive of one or more resources needed by the client device, issuing a reservation request to the roam candidates, where the reservation request includes a timeout feature that persists the reservation at each AP on the list of APs for a set period of time, determining that a second AP within the list of APs will honor the reservation request, and automatically withdrawing the reservation request when the timeout feature has expired and the client device has not connected to the second AP, where the withdrawal of the reservation request frees up the one or more resources associated with the reservation request at each AP on the list of APs.

  • Patent number: 11784037
    Abstract: An electrodeless laser-driven light source includes a laser source that generates CW sustaining light. A pump laser generates pump light. A Q-switched laser crystal is positioned to receive the pump light and generates pulsed laser light in response to the generated pump light that propagates to a breakdown region in a gas filled bulb comprising an ionizing gas. A detector detects plasma light generated by a CW plasma located at least partly in a CW plasma region in the gas filled bulb comprising the ionizing gas and generates a detection signal. A controller generates control signals that control the pump light to the Q-switched laser crystal so as to extinguish the pulsed laser light within a time delay after the detection signal exceeds a threshold level.

  • Publication number: 20230319959
    Abstract: An electrodeless laser-driven light source includes a laser source that generates a CW sustaining light and a pump laser that generates a pump. An optical beam combiner combines the CW sustaining light and the pump such that the CW sustaining light and the pump propagate co-linearly. A Q-switched laser crystal generates pulsed light in response to the pump. A gas-filled bulb is configured such that the pulsed light ignites a pulse plasma in a breakdown region of the gas bulb and the sustaining light sustains a CW plasma in a CW plasma region of the gas bulb, thereby emitting a high brightness light from the gas bulb, where the gas-filled bulb is positioned between the output of the pump laser and the pump input of the Q-switched laser crystal such that the CW plasma absorbs the pump light quenching the pulsed light generated by the Q-switched laser crystal.

  • Publication number: 20230178357
    Abstract: An electrodeless laser-driven light source includes a laser that generates a CW sustaining light. A pump laser generates pump light. A Q-switched laser crystal receives the pump light generated by the pump laser and generates pulsed laser light at an output in response to the generated pump light. A first optical element projects the pulsed laser light along a first axis to a breakdown region in a gas-filled bulb comprising an ionizing gas. A second optical element projects the CW sustaining light along a second axis to a CW plasma region in the gas-filled bulb comprising the ionizing gas. A detector detects plasma light generated by a CW plasma and generates a detection signal at an output. A controller generates control signals that control the pump light to the Q-switched laser crystal so as to extinguish the pulsed laser light within a time delay after the detection signal exceeds a threshold level.

  • Patent number: 11524270
    Abstract: A method of mixing a pharmaceutical solution including adding a gas into an interior compartment of a mix bag to form a headspace. The interior compartment of the mix bag includes a top portion and a bottom portion. The headspace adjacent to the top portion contains gas. The method includes adding a solvent into the mix bag, and establishing a bubble column in the interior compartment by activating a recirculation assembly. The recirculation assembly includes a connecting pathway operably coupled to a recirculation pump. A first end of the connecting pathway is coupled to a top gas recirculation port and a second end is coupled to a bottom gas recirculation port of the mix bag such that the recirculation pump draws the gas from the headspace and delivers the gas to the interior compartment via the bottom gas recirculation port. The method includes adding a solute into the mix bag.
