Sensor with electrically controllable aperture for inspection and metrology systems
Pixel aperture size adjustment in a linear sensor is achieved by applying more negative control voltages to central regions of the pixel's resistive control gate, and applying more positive control voltages to the gate's end portions. These control voltages cause the resistive control gate to generate an electric field that drives photoelectrons generated in a selected portion of the pixel's light sensitive region into a charge accumulation region for subsequent measurement, and drives photoelectrons generated in other portions of the pixel's light sensitive region away from the charge accumulation region for subsequent discard or simultaneous readout. A system utilizes optics to direct light received at different angles or locations from a sample into corresponding different portions of each pixel's light sensitive region. Multiple aperture control electrodes are selectively actuated to collect/measure light received from either narrow or wide ranges of angles or locations, thereby enabling rapid image data adjustment. |

The described embodiments transfer an activity from a source electronic device to a companion electronic device. The source electronic device receives activity information describing an activity performed in a first application at the source electronic device, determines an activity identifier for the activity information, and broadcasts an activity advertisement comprising the activity identifier. Upon receiving the activity advertisement, the companion electronic device determines whether a second application that is associated with the first application is available at the companion electronic device. If the second application is available, the companion electronic device requests extended activity data from the source electronic device. The source electronic device responds by sending extended activity data from the first application to the companion electronic device.

Managing collaboration of shared content using collaborator indexing
Methods, media, and systems for managing access to shared content in a cloud-based service platform. Embodiments operate in a cloud-based environment that comprises storage devices that store content objects accessible by two or more users. The content objects have respective object path attributes and one or more object parent attributes. A server processes collaboration transactions to associate content object sharing between two or more users.

Network intrusion diversion using a software defined network
Methods, devices, and systems are described for diverting a computer hacker from a physical or other targeted production computer to a decoy software-based host emulator that emulates the physical computer. The decoy has the exact same IP address as the physical computer. In order to avoid packet collisions, a programmable physical switch and a virtual networking switch are employed, both of which can use software-defined networking (SDN). The virtual switch prevents packets from the decoy from flowing out of its virtual network until commanded. Upon a command, the physical switch redirects specific flows to the virtual switch, and the virtual switch opens specific flows from the decoy. The specific flows are those with packets containing the hacker's computer IP address, production computer IP address, and production computer port. The packets are associated with TCP connections or UDP sessions. The decoy host emulator can be a virtual machine (VM) running alongside many other VMs in a single computer. If the hacker performs a horizontal scan of the network, additional flows are diverted to other decoy host emulators. |
