The channel structures can be used in conjunction with liquid-based cooling or air-based cooling. The frame can be implemented with low thermal conductivity molding compound or plastic so the heat transfer from one channel structure to another is inhibited. The channel structures can have different configurations (e.g., straight, pillars, and/or pin fins) to provide different rates of flow, mixing, and/or cooling.

The line segments are aligned along lines extending from locations of heads within an image to a vanishing point of a camera that captured the image. Trajectories of actors and visual data are transferred from the cameras to a central server, which links trajectories captured by multiple cameras and locates detected actors throughout the scene, even when the actors are not detected within a field of view of at least one camera. |

Due diligence in electronic documents
Due diligence of documents is faster and simpler. An electronic mortgage application, for example, often contains or references a collection of many separate electronic documents. Electronic data representing an original version of an electronic document and its current version may be hashed to generate digital signatures. Any auditor may then quickly conduct the due diligence by comparing the digital signatures. If the digital signatures match, then the due diligence reveals that the electronic document has not changed since its creation. However, if the digital signatures do not match, then the electronic document has changed since its creation. The auditor may thus flag the electronic document for additional due diligence. Regardless, a result of the due diligence may be incorporated into one or more blockchains. |

Systems and methods for obscuring data from a data source include devices and processes that may objectively measure the information loss for a dataset that is caused by applying a privacy policy, and may select and apply a policy to the dataset based on the measured information loss. The systems and methods may measure the information loss for a large dataset by taking a representative sample from the dataset and applying the policy to the sample in order to quantify the information loss. The quantified information loss can be iteratively used to change the policy in order to meet utility and/or privacy goals, and the system can subsequently apply the changed policy to the dataset. |

Note taking at a device based on whether the user is a known user, unknown user, or owner
When a user approaches or accesses a device, the device attempts to recognize the user. A multi-user note management system takes different actions based on whether the user is recognized as the owner of the device, is recognized as a known user of the device, or is determined to be an unknown user of the device. If the user is recognized as the owner or a known user, the system receives user input and stores the user input as a note. If the user is an unknown user, the system does not allow the user to leave a note at the device, or receives user input and captures an image of the user, and stores the user input as a note associated with the captured image. When the owner of the device unlocks the device after a note has been left, the system displays or otherwise presents the notes. |

Secure area in a file storage system
A system is provided for controlling access to data stored in a cloud-based storage service. Data associated with a user account is stored at the cloud-based storage service. A first request to cause a portion of the data to be associated with a heightened authentication protocol is received. In response, the portion of the data is caused to require the heightened authentication protocol for access. A second request for a file that is stored in the area that is associated with the heightened authentication protocol is received. The second request is authenticated based on the heightened authentication protocol. In response to authenticating the second request, permission is granted to access the file. In response to a failure to authenticate the second request, access to the file is denied, while access to files stored in other areas associated with the user account is allowed. |

Targeted very long delay for increasing speculative execution progression
A computer-implemented method for advancing speculative execution in microarchitectures is disclosed. A non-limiting example of the computer-implemented method includes receiving, by a processor, a test scenario including a first load instruction from a first memory location flagged with a delay notification and a speculative memory access instruction from a second memory following the first load instruction. The method executes, by the processor, the first load instruction from the first memory location and delays a return of data from the first memory location for a number of processor cycles. The method executes, by the processor, the speculative storage access instruction from the second memory location during the delay in returning the data from the first memory location. |

Automatic verification method and system
The application provides an automatic verification method and system, with the method executing in a startup procedure of a host electronic device and including: calculating specific to system information to obtain a set of verification values in the startup procedure when the host electronic device is booted up; comparing a verification value from the set of verification values with a preset verification value from a set of preset verification values according to a preset condition and obtaining a comparison result; decapsulating a key to substitute for a step of manually inputting a password when the comparison result indicates conformity; and decrypting the host electronic device with the key to complete the startup procedure. If the system information is desired to be changed, a proxy device is required to re-calculate according to the changed system information to obtain a new set of verification values to substitute the original preset verification values. |
