    Abstract: A multi-channel audio playback system includes a front speaker, a wearable speaker, and a signal processor. The front speaker is configured to receive front sound field signals (FS). The wearable speaker is designed to allow a listener to hear environmental sounds and is configured to receive rear sound field signals (RS). The signal processor is configured to divide a multi-channel signal into a front sound field signal group (FSG) and a rear sound field signal group (RSG); mix FSG (RSG) and generate the FS (RS), wherein the number of the FS (RS) is equal to the number of the drivers of the front speaker (wearable speaker); and perform time delay adjustment on FS or RS, so that a difference between times for sound waves emitted by the front speaker and by the wearable speaker to respectively reach ears of the listener is less than a default value.

    Abstract: A cloud design composition negotiation system includes a cloud design composition server including a database storing design composition data. A partial change program can access variable data in a variable data section. A processing unit executes partial change in the design composition data. An execution end operating unit is linked with the database and is operable by clicking a style selection program and an area selection program to present a style selection icon and an area selection icon on a screen, thereby obtaining one of the design composition data. Icons of a composition of the one of the design composition data are shown on the screen. The partial change program presents a partial change icon on the screen. Clicking the partial change icon enables an execution end user to access the variable data section to thereby proceed with partial change in the icons of the composition.

    Abstract: A device for synthesizing a high dynamic range image based on per-pixel exposure mapping includes an image-capturing module, an image-processing module, and a recursive control module. The image-capturing module serves to obtain a plurality of source images each having a unique exposure value. The image-processing module uses an exposure-value modulating means to perform exposure synthesis to pixels on an identical location of two of the source images that have similar exposure values according to exposure values of the pixels, so as to form synthesis images. The recursive control module sends the synthesis images back to the image-processing module for reprocessing until the image-processing module generates a single synthesis image.

    Abstract: A circuit has a first circuit module including a first resistor and first and second transistors coupled in parallel with the first resistor. The first resistor and the first and second transistors are coupled together at a first node. An equivalent resistance across the first circuit module increases as a voltage of the first node is increased from a first voltage to a second voltage, and the equivalent resistance across the first circuit module decreases as the voltage of the first node is increased from the second voltage to a third voltage.
