in face detection and recognition, digital audio and video codec technology, content-based multimedia data retrieval, multi-function sensing technology, especially in the field of digital audio and video codec technology, face detection and recognition technology, Chinese Sign language recognition and synthesis and other fields to make many original work.My research direction and development historyUnder the VIPL Research Group and Joint Laboratory Research Framework, I have been focusing on co

highest 1.5mb/s speed, either through the d+ pin or the D-pin (two stitches in the middle). Speed limit is due to the fact that the HCI device is always declared as a "low Speed Device" (USB 2.0 compliance) This serial signal is decoded at the computer's USB controller and is further explained by the universal keyboard driver for the man-machine interaction device. The code values of the keys are then transferred to the hardware abstraction layer

seen as an independent function body or a collection of functions capable of accomplishing certain functions.Each task has a task ID, which has a priority function, similar to the priority of Ucos.The difference between the RW kernel and the ucos is that the ucos is a multitasking kernel that has time slices in turn and has a mutex synchronization.Iv. Message4.1 Message IDA message distinguishes between what task it belongs to and the different messages within the same task. So a message consis

Because the work signed is the development of Bluetooth protocol stack, and is the kind of bottom, the assembly is the only tool for the company platform. But the things in the past always do not want to be wasted, design patterns, C, those used more handy things. So, still want to do something, this time last year, has been busy to a domestic audio codec company to do supporting the HCI Bluetooth chip, they use the Cortext M3 core, and the bottom of

transmission mechanisms for Bluetooth HCI data groups. The bluz Stack also supports these two transmission mechanisms (Drivers/Bluetooth /). Figure 4 shows the relationship diagram of the android Bluetooth part. Android includes support for the Bluetooth protocol stack, which enables Bluetooth devices to wirelessly connect to other Bluetooth devices for data exchange. The Android Application Framework provides APIs for accessing the Bluetooth

Example One Suppose we want to test the member function of the following class: int mode2 (int nparam), the software automatically generates the following 6 test cases for us when we do the White box test: Nparam = 1, 0,-1, 2147483647,-2147483647, 230 It can be seen t

Interaction efficiency is an important component of product availability and a key point of usability assessment. Compared with the traditional Internet products, the current mobile products in the soft and hard interface of the synergy and network environment There are many gaps, the user's interaction efficiency at a relatively low level. Some thoughts on the interactive efficiency of mobile products make it meaningful for us to design the mobile products with higher interaction efficiency and

keyboard, convert the count to two. How to be prepared If you have ever done design work and have a team experience, we welcome you and you will do better. If you have no experience, here are a few ways to help you improve your design skills: If you are still in school, you are advised to take more project-based courses. This will give you more practical design experience. Use every opportunity to develop your design concept. Keep asking yourself: "How can you design it differently? How do

BlueZ Introduction:Linux OS Open Bluetooth protocol stacks mainly include IBM's Bluedrekar, Nokia's affix, Axis's OPENBT and the official protocol stack BlueZ.Bluetooth protocol stack BlueZ is divided into two parts: kernel Code and User state program and toolset.The kernel code consists of the BlueZ core protocol and the driver , and the Bluetooth protocol is implemented in the kernel source code/net/bluetooth. Including the implementation of HCI,L2C

: Usually a physical device that sends and receives radio signals and knows how to translate these signals into packets carrying information;-Host: Usually a software stack that manages how the two devices communicate and how to use the radio to provide several different services at the same time;-Application: Application section, using the software stack to implement user instances. Link Layer Link Layer, which is the most complex part of BLE, is responsible for broadcasting, scanning, establis

relevant fields of graphics are related to human subjects, such as virtual reality and man-machine interaction (HCI). In addition, many of the problems with computers depicting the real world involve the probability of various unknown events. Two examples: a long tree, the probability of its branches branching; how the virtual animal determines its walking route. Finally, some techniques of solving the high difficulty equations are used to estimate t
