Abstract: A memory system having multiple address tables to translate logical addresses to physical addresses at different granularity levels is disclosed. For example, a first address table is associated with a first block size of translating logical addresses for accessing system files and application files; and a second address table is associated with a second block size of translating logical addresses for storing and/or retrieving data from an image sensor of a surveillance camera. A user interface can be used to access a configuration option to specify the second block size; and a user may indicate a typical size of an image or video file to be recorded by the surveillance camera to calculate the second block size and thus configure the second address table for a partition to record the image or video files.

Abstract: Systems, devices, and methods related to a deep learning accelerator and memory are described. For example, a removable media (e.g., a memory card, or a USB drive) may be configured to execute instructions with matrix operands and configured with: an interface to receive a video stream; and random access memory to buffer a portion of the video stream as an input to an artificial neural network and to store instructions executable by the deep learning accelerator and matrices of the artificial neural network. Such a removable media can be used to replace an existing removable media used in a surveillance camera to record video or images. The deep learning accelerator can execute the instructions to generate analytics of the buffer portion using the artificial neural network, enabling the surveillance camera that is upgraded via the use of the removable media to provide intelligent services based on the analytics.

Abstract: Systems, devices, and methods related to video surveillance as a service (VSaaS) are described. For example, a removable storage device, such as a secure digital (SD) memory card or a micro SD card, can be configured to run a virtual camera agent. When the removable storage device is inserted into a digital camera to provide a storage capacity for the digital camera, the agent can convert the video captured by the digital camera into video captured by a virtual camera. The virtual camera can be configured to be in compliance with the camera requirements of a VSaaS platform. Thus, a digital camera not in compliance with the platform can still be used with the platform through the deployment of the virtual camera that is enabled by the removable storage device.

Abstract: An antenna structure with wide radiation bandwidth in a reduced physical space includes a housing, a first feed portion, and a second feed portion. The housing includes a metallic side frame, a metallic middle frame, and a metallic back board. The metallic side frame defines a first gap and a second gap. The metallic back board defines a slot. The slot, the first and second gaps divide a first radiation portion and a second radiation from the metallic side frame. The first feed portion is electrically connected to the first radiation portion. The second feed portion is electrically connected to the second radiation portion. The metallic middle frame and the metallic back board are connected to each other to form a system ground plane to provide a ground for the antenna structure.

Abstract: An antenna structure with wide radiation bandwidth in a reduced physical space includes a housing, a first feed portion, and a second feed portion. The housing includes a metallic side frame, a metallic middle frame, and a metallic back board. The metallic side frame defines first and second gaps, and the metallic back board defines a slot. The slot, the first gap, and the second gap divide the metallic side frame to give a first radiation portion. The first and second feed portions are both electrically connected to the first radiation portion. When the first feed portion supplies a current, the current flows through the first radiation portion, toward the second gap to excite a first working mode. When the second feed portion supplies a current, the current flows through the first radiation portion, toward the first gap to excite a second working mode.
