A structure of a structure release and a manufacturing method are provided. The structure and manufacturing method are adapted for an interference display cell. The structure of the interference display cell includes a first electrode, a second electrode and at least one supporter. The second electrode has at least one hole and is arranged about parallel with the first electrode.

The present invention pertains to a wireless audio-video doorbell monitoring system, wherein a portable monitoring device administrates a doorbell device and detective devices. After initiation, the monitoring device calls other nearby devices to form a wireless network via a wireless broadcasting way, and then the monitoring device administrates each device to perform the doorbell or detection function. Via the automatic setup and simple operating interface, the present invention enables a general family to be free from a complex operational procedure. In the present invention, the detective device can sense the image and sound of the monitored regions, which is sent to a display panel and a speaker of the monitoring device without a time lag. Accordingly, the present invention provides an instantaneously-displaying and easy-operated wireless audio-video doorbell monitoring system, which is easy installed, automatically set up, highly securing, able to reduce the power consumption efficiently and suitable for a general family usage.

CBR control strategies provide constant or relatively constant bitrate output with variable quality. The control strategies include various techniques and tools, which can be used in combination or independently. For example, an audio encoder uses a trellis in two-pass or delayed-decision CBR encoding. The trellis nodes are states derived by quantizing buffer fullness values. The transitions between nodes of a previous stage and nodes of a current stage depend on encoding a current chunk of audio at different quality levels. When pruning the trellis, the encoder uses a cost function that considers smoothness in quality as well as quality in absolute terms. The encoder may store compressed data at different quality levels, then output the compressed data after simplification of the trellis to a suitable point. If the two-pass or delayed-decision CBR encoding fails, the encoder uses one-pass CBR encoding for the sequence or part of the sequence.

Methods of filling gaps with tungsten are described. The methods include a tungsten dep-etch-dep sequence to enhance gapfilling yet avoid difficulty in restarting deposition after the intervening etch. The first tungsten deposition may have a nucleation layer or seeding layer to assist growth of the first tungsten deposition. Restarting deposition with a less-than-conductive nucleation layer would impact function of an integrated circuit, and therefore avoiding tungsten “poisoning” during the etch is desirable. The etching step may be performed using a plasma to excite a halogen-containing precursor while the substrate at relatively low temperature (near room temperature or less). The plasma may be local or remote. Another method may be used in combination or separately and involves the introduction of a source of oxygen into the plasma in combination with the halogen-containing precursor.

A stall detection circuit and method for a stepper motor. The circuit has an H-bridge configuration with an additional circuit pathway to ground being connected at a point between two center windings. During the transition between step sequences, the circuit employs a monitoring phase in which the previously active low side driver is turned off such that current passes through only the first winding and then is diverted to ground via the additional pathway. While the phase voltage is thus momentarily extinguished, the second coil is used to monitor the motor's back EMF, from which it can be determined whether the rotor is in a normal running mode, a stall, or a reverse condition.

The area or confluency of a sample is determined by obtaining quantitative phase data relating to the sample and background surrounding the sample. The boundary of the sample is determined from the quantitative phase data by forming a histogram of phase data measurements and taking the derivative of the histogram to thereby determine the point of maximum slope. The line of best fit on the derivative is used to obtain a data value applicable to the boundary so that data values either above or below the determined data value are deemed within the sample.
