Abstract: Methods, systems, apparatuses, and computer program products are provided for enabling access to a resource in a secured manner. A token request from an application executing in a first computing environment may be received in a second computing environment. The second computing environment may assign a trust level to the received token request that indicates that the first computing environment may not be trusted. The token request, along with the trust level, may be provided to an authorization server to generate an authorization token that includes a trust indication indicative of the trust level of the second computing environment. When the application executing in the second computing environment transmits the authorization token to a resource manager to access a resource, the resource manager may be configured to perform a precautionary action to protect the resource prior to providing access, such as creating a backup of the resource.

Abstract: A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format.

Abstract: The End-to-End Encryption and Hot Wallet Key Recovery Apparatuses, Processes and Systems (“E2EEHWKR”) transforms key backup request, key recovery request datastructure/inputs via E2EEHWKR components into key backup response, key recovery response outputs. A key backup request datastructure specifying a wallet private key, a private key backup server identifier, a PIN shard fracture scheme definition, and a plurality of PIN shard backup devices is obtained. A user security PIN is obtained and utilized to encrypt the wallet private key. A symmetric key is calculated from a public key associated with the private key backup server identifier and an app private key. The encrypted wallet private key is encrypted utilizing the symmetric key. The twice encrypted wallet private key is sent to a private key backup server. The user security PIN is encrypted utilizing an asymmetric keypair. Encrypted user security PIN shards are generated and sent to PIN shard backup devices.

Abstract: In an embodiment, during an overload or short circuit condition, a current limit circuit of an inverter is utilized in a pulse-by-pulse manner, which in turn causes the AC output of the inverter to operate in a hiccup mode (e.g., pulse-by-pulse based on and off dependent upon the output current) and automatically recover once the operating parameters (e.g., output current) are within the proper ranges. The pulse-by-pulse current limit circuit is configured to protect the switching circuits of the inverter from shorting or device failure during any peak operating voltage conditions by ensuring on/off timing accuracy of the inverter.
