Abstract: In one or more embodiments, one or more systems, methods, and/or processes may determine that a first vehicle is unsafe to continue navigating to the drop-off location while the first vehicle is traveling en-route to transport one or more passengers to a drop-off location. Based on this determination, an intermediate area for the one or more passengers to be dropped off by the first vehicle and picked up by a second vehicle is determined. Instructions are then provided to the first vehicle to cause the first vehicle to navigate to the intermediate area. Further, instructions are provided to the second vehicle to navigate at least in proximity to the intermediate area to pick up the one or more passengers, and navigate to the drop-off location after picking up the one or more passengers.

Abstract: The present disclosure is directed methods and apparatus that improve the energy efficiency of an air filtration apparatus while maintaining a high level of filtration capabilities. Air filtration apparatus consistent with the present disclosure may include an input, a fan, a pre-filter, and electrical conductors that provide a high voltage used to charge particles in an air flow. This apparatus may also include a secondary filter that traps charged particles. The pre-filter may filter air using conventional means, where a high energy electric field generated by high voltage conductors may charge particles in the air such that those particles may clump together and be captured in the secondary filter. These clumping effects may allow a less dense filter media to capture particles that would otherwise pass through the less dense filter. Micro-organisms attached to the captured particles may be degraded or destroyed after they are captured in the secondary filter.

For instance, an enclave manager may be created in an untrusted environment of a host computing device. The enclave manager may include instructions for creating one or more enclaves. An enclave may be generated in memory of the host computing device using the enclave manager. One or more enclave clients of the enclave may be generated by the enclave manager such that the enclave clients configured to provide one or more entry points into the enclave. One or more trusted application instances may be created in the enclave.

Abstract: Methods, systems, and computer-readable media for customized domain name resolution for virtual private clouds are disclosed. A domain name system (DNS) resolution service receives a DNS request from a computing resource associated with a virtual private cloud (VPC) in a cloud provider network. The service determines that the VPC is associated with one or more firewall rules. Responsive to determining that the VPC is associated with the firewall rule(s), the service determines whether the DNS request is allowed or blocked according to the one or more firewall rules. If the DNS request is allowed, the service resolves the DNS request using a DNS server and returns a response to the computing resource. If the DNS request is blocked, the service does not resolve the DNS request.

Abstract: Sensors on an aerial lift device determine the number of occupants in and occupant portion of the aerial lift device. Prior to permitting the occupant portion to rise up off the ground, the system checks the engagement of safety harnesses to verify that the number of engaged safety harnesses matches the number of occupants in the occupant portion of the aerial lift. If the number matches, operation of the aerial lift may be enabled and the occupant portion deployed. If the number does not match, an alarm is sounded and deployment of the occupant portion may be disabled. With pre-deployment safety testing, and no occupants in the occupant portion, the occupant portion may be deployed to verify all operational status of the occupant portion with no occupants. The system may further create a data log to verify the time and successful pre-deployment safety check.

Abstract: Methods and apparatus of the present disclosure monitor and change operation of an air filtering system or apparatus dynamically over time. Changes to the air filtering apparatus may be associated with a type of facility and air purity requirements associated with the type of facility. Examples of different types of facilities include an office building, a clean room, and a hospital. Apparatus of the present disclosure may include conventional air filters and may include disinfecting air filter sub-assemblies that use a high voltage to charge particles in the air such that those particles may conglomerate and be captured more easily in an air. Methods consistent with the present disclosure may change an air flow rate or may change the voltage used to charge the air particles as conditions associated with the air of a facility change over time.

Abstract: A system receives historical vehicle battery data from a gateway device connected to a vehicle. Some vehicles with plug-in rechargeable batteries recommend/require that the vehicle computer be turned off when recharging. Thus, obtaining a current state of charge while a vehicle is charging can be difficult because the vehicle computer can be off. While the vehicle/gateway device is unable to transmit current battery data, the systems estimate a battery charge from the historical data.
