摘要： An electromechanical variable fluid flow restrictor includes a support having a passage and a seal surface, a deformable seal that is engageable with the seal surface, and a bias member for exerting an electronically controlled variable bias against the deformable seal. The seal surface includes channels formed in its surface that extend beneath the deformable seal. The bias member can exert a bias sufficient to cause the deformable seal to fill the channels, preventing fluid flow through the channels. When the bias member decreases the bias against the deformable seal, the deformable seal gradually moves out of the channels, allowing fluid flow through the channels, and through the passage in a flow control. The deformable seal does not need to separate from the seal surface to allow fluid flow. Instead, fluid flows through the small, controlled flow areas created when the deformable seal withdraws from the channels. Because the deformable seal does not separate from the seal surface, oscillations are not created in the fluid flow, which provides for stable flow through the flow control.
摘要翻译：机电可变流体流量限制器包括具有通道和密封表面的支撑件，可与密封表面接合的可变形密封件，以及用于对可变形密封件施加电子控制的可变偏压的偏置构件。密封表面包括在其表面上形成的在可变形密封件下方延伸的通道。偏置构件可以施加足以使可变形密封件填充通道的偏压，防止流体流过通道。当偏置构件减小针对可变形密封件的偏压时，可变形密封件逐渐移出通道，允许流体流过通道，并且在流量控制中通过通道。可变形密封件不需要与密封表面分离以允许流体流动。相反，流体流过可变形密封件从通道退出时产生的小的受控流动区域。因为可变形密封件不与密封表面分离，所以在流体流中不产生振荡，这提供了通过流量控制的稳定流动。

摘要： An image sensor includes an array of pixels arranged in rows and columns. A reference current source provides the reference current to a transistor forming one half of a current mirror. Each column has a current source, which forms the other half of a current mirror. A switch is provided to selectively connect a resistance between ground and the transistor. When the resistance is connected, the transistor is starved of gate-source voltage, which reduces the current supplied by each current source.

摘要： Methods and system for sub-ambient pressure control for column head pressure in gas chromatography (GC) systems. The GC system includes an inlet and a capillary column connected to the inlet. The inlet includes a valve that regulates an inlet pressure and pressure sensor that measures the inlet pressure and outputs a signal that indicates a measured inlet pressure. The GC system also includes an inlet-pressure set-point that can be set to a negative pressure set-point representing a pressure below ambient pressure, the negative pressure set-point driving the valve to change the inlet pressure until the measured inlet pressure equals the negative pressure set-point.

摘要： Lighting flicker in the output of a video imaging device is detected. The video imaging device has a main picture area divided into pixels for producing successive images at a frame rate. A series of signals are produced from at least one additional picture area adjacent the main picture area, with the additional picture area having a size substantially larger than a pixel. Each of the signals is a function of light incident on the additional picture area in a time period substantially shorter than that of the frame rate. A predetermined number of the signals are accumulated to form a series of compound samples, and the compound samples are filtered to detect components indicating the lighting flicker. The filtering is performed using a bandpass filter tuned to the nominal flicker frequency. The compound samples are formed at a sample rate which is a multiple of the nominal flicker frequency, and the filtering is performed by taking the fundamental output component of a radix-N butterfly.

摘要： Solid state image sensors, and methods of operation thereof, includes an array of photosensitive pixels arranged in rows and columns and in which pixel data signals are read out from the pixels via column circuits, which introduces column fixed pattern noise to the signals. The signals are selectively inverted at the inputs to the column circuits and the inversion is reversed following output from the column circuits. Each column circuit may include an analog-to-digital converter and a digital inverter for inverting digital output therefrom. The selective inversion may be applied to alternate rows or groups of rows of the pixel data, and may be applied differently to different frames of the pixel data. These techniques result in column fixed pattern noise being modulated in a manner which makes the noise less apparent to the eye, and which facilitates subsequent cancellation of the noise.
摘要翻译：固态图像传感器及其操作方法包括以列和列排列的光敏像素的阵列，其中通过列电路从像素读出像素数据信号，该列电路将列固定图案噪声引入信号。这些信号在列电路的输入端被选择性地反相，并且在从列电路输出之后反转反转。每列电路可以包括模数转换器和用于反转数字输出的数字反相器。选择性反转可以应用于像素数据的行的交替行或组，并且可以不同地应用于像素数据的不同帧。这些技术导致列固定模式噪声以使噪声对眼睛不太明显的方式进行调制，并且有助于随后的噪声消除。

摘要： An active pixel array has the signal output of each pixel connected to a first column conductor, and a reset switch connected to a second column conductor. The first and second column conductors are connected to a read-reset amplifier. The read-reset amplifier operates in a first mode in which a reset voltage is applied to the second column line, and in a second mode in which pixel output signals are buffered from the first column line. The read-reset amplifier can also operate as a comparator forming part of an ADC circuit.
