Cleaning of depth data by elimination of artifacts caused by shadows and parallax
Multiple Holocam Orbs observe a real-life environment and generate an artificial reality representation of the real-life environment. Depth image data is cleansed of error due to LED shadow by identifying the edge of a foreground object in an (near infrared light) intensity image, identifying an edge in a depth image, and taking the difference between the start of both edges. Depth data error due to parallax is identified noting when associated text data in a given pixel row that is progressing in a given row direction (left-to-right or right-to-left) reverses order. Sound sources are identified by comparing results of a blind audio source localization algorithm, with the spatial 3D model provided by the Holocam Orb. Sound sources that corresponding to identifying 3D objects are associated together. Additionally, types of data supported by a standard movie data container, such as an MPEG container, is expanding to incorporate free viewpoint data (FVD) model data. This is done by inserting FVD data of different individual 3D objects at different sample rates into a single video stream. Each 3D object is separately identified by a separately assigned ID. |

Server using proof-of-work technique for hardening against denial of service attacks
A computerized device and a process protect against denial-of-service (DoS) attacks by using a memory-time hard problem that a client (e.g., IoT device or mobile app) solves as part of a request such as an initial registration process.

Detecting and mitigating wardriving
Determining the physical location of wirelessly connected devices within a network can provide a number of security benefits. However, manually determining and configuring the physical location of each device within a system can be burdensome. To ease this burden, devices within a network are equipped with a location detection sensor that is capable of automatically determining a device's location in relation to other devices within the network. A location detection sensor (“sensor”) may include a light source, a light direction sensor, a rangefinder, and a radio or wireless network interface. Two location detection sensors can perform a location detection process to determine their relative locations to each other, such as the distance between them. As more sensors are added to a network, a sensor management system uses the relative locations determined by the sensors to map the sensors to a physical space layout. |

Smart routing synchronization system and methods for socializing a synthetic rebroadcast and group stream
Smart routing synchronization systems socialize a synthetic rebroadcast or group stream for enabling members of a user group to (re)broadcast select content to other members of the user group and collaboratively curate content delivery.

DAC servo
A servo block in a Buck, Boost, or switching converter allows a positive offset to be applied to the DAC voltage. In a typical switching converter application, the load will have a positive current, sourced from the switching converter to ground through the load. This will cause the output voltage of the switching converter to fall with the output impedance. The servo block corrects the output voltage by adjusting the DAC voltage upwards. In the case where current is forced back into the switching converter, causing the output voltage to rise, the servo block will have affect. The behavior of the servo block is desirable as it reduces the negative affect the servo block may have on load transients occurring when the switching converter is in over voltage. In particular, the idea of shifting the DAC voltage for several different loops with a single servo block is disclosed. This scheme is particularly effective for a switching converter design, allowing the slow loop integrator and fast existing switching converter control loops to be considered almost independently. |
