Abstract: Techniques are disclosed pertaining to performing upgrades by upgrade controllers. A node upgrade controller determines to upgrade a first set of nodes, of a plurality of nodes, on which executes a first set of pods that facilitate access to an instance of a particular component. The node upgrade controller obtains a lock on the plurality of nodes to prevent a pod upgrade controller from upgrading a second set of pods that execute on a second set of the plurality of nodes and facilitate access to another instance of the particular component. The unavailability of the first and second sets of pods causes a requisite number of instances of the particular component to be unavailable. The node upgrade controller upgrades the first set of nodes and releases the lock to allow the pod upgrade controller to obtain a lock on the plurality of nodes.

Abstract: The present disclosure relates to a helmet including a shell, a housing comprising a front panel and a rear panel that form a chin portion of the shell, an electronic board disposed within the housing, a battery disposed within the housing and coupled to the electronic board, a camera disposed within the housing and coupled to the electronic board and the battery. The camera comprises a lens that extends through the front panel of the housing. The housing does is embedded within an external profile shape of the helmet.

Abstract: The present disclosure relates to a visual communication system for a helmet comprising: an array of light emitting devices arranged inside the helmet in a manner such that light emitted by the light emitting device is visible by a user of the helmet; a data communication interface arranged to receive situational related data from one or more sources; and a processing module arranged to process the situational related data and generate a light signal providing driving or riding guidance to the user of the helmet.

Abstract: Techniques are disclosed relating to upgrading nodes. A computer system may detect that an updated node image has been created that is an update to a previous node image used to deploy a plurality of nodes into an environment associated with the computer system. The computer system may determine an upgrade order in which to upgrade a set of the plurality of nodes. The upgrade order may be determined based on a rank associated with a given node of the set of nodes by a ranking service. The computer system may then upgrade the set of nodes according to the upgrade order. The upgrading of a first node of the set of nodes may include deploying a second node based on the updated node image and then evicting a set of application pods from the first node and redeploying the set of application pods onto the second node.
