  • Patent number: 12136711
    Abstract: A battery safety system includes a flow valve and a sensing device. The flow valve is disposed on a housing of the battery and includes a first valve that is embedded inside the housing and a second valve that intersects the housing. The first valve includes a cavity through which analytes released upon electrochemical reactions within the battery flow towards the second valve. The second valve extends through the housing to the outside, and defines an opening through which the released analytes exit the housing. The sensing device is disposed within the cavity of the first valve of the valve and is situated in a manner to be in fluidic contact with the released analytes as they flow from the inside of the battery to the outside. In some aspects, the battery safety system can detect a minute presence of one or more analytes. In some aspects, the sensor is in communication with a battery management system.

  • Patent number: 12074917
    Abstract: This disclosure describes, in part, techniques for sharing content associated with network applications. For instance, a user may want to share content for a network application, such as a game stream for a gaming application. As such, system(s) may launch a broadcasting session on a first virtual server and launch the network application on a second virtual server. The first virtual server may then receive content data representing states of the network application from the second virtual server. Additionally, the first virtual server may receive video data representing the user and/or audio data representing user speech from a user device. The first virtual server may then generate broadcasting data using the content data, the video data, and the audio data. After generating the broadcasting data, the system(s) may send the broadcasting data to one or more computing devices associated with a user account.

  • Publication number: 20240262679
    Abstract: A venting device includes an anchor structure and a membrane. The membrane is anchored on the anchor structure and configured to form a first vent and a second vent. The membrane includes a first flap, a second flap and a third flap. The membrane partitions a space into a first volume and a second volume, and the first volume and the second volume are connected when the first vent and the second vent are formed. The first flap is actuated to move toward a first direction and the second flap is actuated to move toward a second direction opposite to the first direction, so as to form the first vent. The first flap is actuated to move toward the first direction and the third flap is actuated to move toward the second direction opposite to the first direction, so as to form the second vent.
