摘要:
The present invention discloses a role exchange method for Bluetooth system. It comprises the steps of: a first slave asking role exchange and transmitting a FHS packet to a first master at a first time point t1; the first master exchanging as a second slave at the second time point t2; the first slave re-transmitting a plurality of FHS packet; and the first slave exchanging as a second master automatically. The role exchange method according to the present invention can solve the failure problem of role exchange procedure due to the noise in the conventional Bluetooth scheme.

A channel quality evaluation method applicable to Bluetooth wireless network sends a first channel detecting format packet from the Bluetooth master to the Bluetooth slave. The master verifies if the slave recognizes the first channel detecting format packet from the response from the slave. If the Bluetooth slave does not recognize the first format detecting packet, the Bluetooth master will send a second channel detecting format packet. The error rate is to be calculated according to the response from the Bluetooth slave to obtain an estimate of the channel qualify. This method obtains the channel quality efficiently and does not interfere with the normal operation of the Bluetooth devices.

The wireless communication apparatus includes a blue tooth wireless earphone that can be operated independently and a network phone base. The blue tooth wireless earphone is embedded into the network phone base. When the blue tooth wireless earphone is used independently, a voice is inputted and outputted via a microphone and a loudspeaker of the blue tooth wireless earphone, respectively. Once the blue tooth wireless earphone is used in combination with the network phone base, the voice is inputted and outputted via a microphone and a loudspeaker of the network phone base. The blue tooth wireless earphone is also used independently to be connected to a blue tooth mobile phone, a PDA, etc. Furthermore, by being connected to an external apparatus through a USB interface, the blue tooth wireless earphone is charged by the network phone base, and such a design is also applicable in a hands-free car earphone.

A Bluetooth audio chip with multiple input/output sources is implemented on a monolithic integrated circuit. The Bluetooth audio chip includes a Bluetooth Baseband/RF module, an encode/decode module, a stereo ADC/DAC codec module, a USB module, a UART module, and a flash memory. Each one of the modules receives/transmits one kind of audio source, thus the Bluetooth audio chip has deeply embedded with multiple input/output sources. The Bluetooth audio chip is used in a diversity of applications to reduce the cost and time comparing to one purpose chip for just only one specific application.

An image retrieval method applies an application server, one or more calculating servers, and a sorting server to perform image retrieval. The application server extracts visual features of an exemplary image. The one or more calculating servers calculate similarities of available images according to the visual features of the exemplary image. The sorting server sorts the available images according to the similarities so as to obtain images similar to the exemplary image.

A method for isolating and cutting out figures in a design patent document divides each page of a figure section of the design patent document into a multiplicity of areas according to histograms, which are created based on information of black pixels and white pixels in a black-and-white image of the page. The method selects the areas that include the figures of the design patent, and displays the selected areas on a display device.

The plurality of power supply systems is mounted within the transportable container.
摘要:
An image processing system and method for comparing and correcting two monochromic images A2 and B2 that extracts a skeleton of objects in the monochromic image A2 to generate a skeleton image A3 and extracts a skeleton of objects in the monochromic image B2 to generate a skeleton image B3. The system and method then covers the skeleton image A3 with the monochromic image B2 to generate a covered image A4, and covers the skeleton image B3 with the monochromic image A2 to generate a covered image B4. The system and method further corrects allowable variances in the covered images A4 and B4, and outputs the covered images whose variances have been corrected.
摘要:
A method for merging separated pixel blocks into an integral image of an object is provided. The method performs binary image processing on an obtained image to obtain a binary image, finds pixel blocks in the binary image whose area is greater than a first preset value, and stores a position and a size of each found pixel block in a data structure. The method further merges two pixel blocks in the data structure if a distance between the two pixel blocks is less than a second preset value, so as to generate the integral image of the object.
摘要:
A method embeds product information in videos with product placements using an electronic device. The electronic device defines product information of one or more products that are embedded in a video, and embeds the product information in an image file having a file format that is compatible with the video, the embedding according to appearance times of the one or more products. During display of the video on the display device, the electronic device determines whether the image file includes product information about a product that is presented during display of the video. If the image file includes product information about the product, the electronic device displays a prompt on the display device concurrently with the product. After receiving a selection operation to select the prompt, the electronic device displays the product information on the display device.
