In this way, a connection may be established on the server to the storage resource for a given client browser. That connection may be utilized repeatedly to access data that is needed without reaccessing a web page. In some embodiments, this results in greater data access speed and less overhead, for example, in connection with remembering the various user selections that predate a given storage resource access request. |

Connection leasing for hosted services
Aspects herein describe techniques for brokering hosted resources in a virtual desktop infrastructure (VDI) using connection leases to reduce demand on connection brokers and to allow hosted services to be maintained even in the event of a broker outage. When a client device desires to connect to a hosted resource (e.g., a hosted desktop or a hosted application), the client device may present a lease token to the session host. The lease token is a self-sustaining package of data from which a session host can determine whether the requesting client device is authorized to access one or more resources hosted by that session host. The lease token may be cryptographically signed to ensure its contents have not been altered, and further that the lease token originated from a trusted source. Lease tokens may be stored independently from a connection broker, thereby still being usable if the connection broker goes offline. |

Remote industrial monitoring using a cloud infrastructure
A cloud-based infrastructure facilitates gathering, transmitting, and remote storage of control and automation data using an agent-based communication channel. The infrastructure collects the industrial data from an industrial enterprise and intelligently sorts and organizes the acquired data based on selected criteria. Message queues can be configured on the cloud platform to segregate the industrial data according to priority, data type, or other criteria. Behavior assemblies stored in customer-specific manifests on the cloud platform define customer-specific preferences for processing data stored in the respective message queues. Web-based tools can deliver automated notifications to an end user device based on analysis of the stored data, and allow the user to remotely view the stored data. |

Integrated circuit capacitor including dual gate silicon-on-insulator transistor
Dual gate FD-SOI transistors are used as MOSFET capacitors to replace passive well capacitors in analog microcircuits. Use of the dual gate FD-SOI devices helps to reduce unstable oscillations and improve circuit performance. A thick buried oxide layer within the substrate of an FD-SOI transistor forms a capacitive dielectric that can sustain high operating voltages in the range of 1.2 V-3.3 V, above the transistor threshold voltage. A secondary gate in the FD-SOI transistor is used to create a channel from the back side so that even when the bias voltage on the first gate is small, the effective capacitance remains higher. The capacitance of the buried oxide layer is further utilized as a decoupling capacitor between supply and ground. In one example, a dual gate PMOS FD-SOI transistor is coupled to an operational amplifier and a high voltage output driver to produce a precision-controlled voltage reference generator. In another example, two dual gate PMOS and one dual gate NMOS FD-SOI transistor are coupled to a charge pump, a phase frequency detector, and a current-controlled oscillator to produce a high-performance phase locked loop circuit in which the decoupling capacitor footprint is smaller, in comparison to the conventional usage of passive well capacitance. |
