The dual cameras of the Apple iPhone 7 Plus have been receiving high attention because of their possibility of 3D mapping, and they were once passed as the layout of the "AR mobile phone." Nowadays, Apple has submitted a new patent No. 9456307. According to the patent description, in this portable system, the data in the laser sensor and the positioning circuit are combined to create an accurate depth map of the user's surroundings. So it seems that the new Apple mobile phone dual camera is quite possible for the layout of the AR.
In many ways, 3D mapping uses lasers to complete the projection. For example, Microsoft's HoloLens glasses do the mapping of the rooms. Google's Tango cameras do the same. Apple also purchased PrimeSense, a 3D depth mapping company. The new patent, titled "Electronic Devices with Mapping Circuits," may allow an iPhone to use mapping applications, use laser sensors and laser beams to obtain room measurements, including shapes, distances, and environmental object characteristics. Quantity.
Apple has been exploring the acquisition of AR resources in recent years. From a lot of details it can be seen that Apple's interest in AR is far greater than VR. Faced with the increasing competition pressure of the mobile phone industry, the iPhone series that has been repeatedly "small reforms" has been difficult to support the huge expenses on technology research and development. Apple itself also urgently took out the corresponding black technology to consolidate the status of the "first brother."
For now, mobile devices are still a long way from real AR functionality, but nobody knows how much "black technology" Apple has stocked. At the moment when major corporations are involved in VR heat, to realize AR functions on mobile phones, it seems that only Apple has the most potential.
The task of the managed switch is to keep all network resources in good condition. The network management switch product provides a variety of network management methods based on the terminal control port (Console), based on the Web page, and supports Telnet to remotely log in to the network. Therefore, network administrators can perform local or remote real-time monitoring of the switch's working status and network running status, and manage the working status and working mode of all switch ports in a global view.
The switch is the most important network connection device of the LAN, and the management of the LAN mostly involves the management of the switch.
The network management switch supports the SNMP protocol. The SNMP protocol consists of a set of simple network communication specifications, which can complete all basic network management tasks, has a small demand for network resources, and has some security mechanisms. The working mechanism of the SNMP protocol is very simple, mainly through various types of messages, namely PDU (protocol data unit) to achieve the exchange of network information.
There are also Managed Switches that provide policy-based QoS (Quality of service). Policy refers to the rules that control the behavior of the switch. The network administrator uses the policy to allocate bandwidth and priority for application flows and control network access. The focus is on the bandwidth management strategy required by the service level agreement and the way of publishing the policy to the switch. Multifunction light emitting diodes (LEDs) used to indicate port status, half duplex/full duplex and 10BaseT/100BaseT at each port of the switch, and switch status LEDs that indicate system, redundant power supply (RPS) and bandwidth utilization A comprehensive and convenient visual management system has been formed.
