The 2nd dipole antenna section includes a 2nd radiation section and a 2nd frequency section. The 1st and 2nd dipole antenna sections are electrically coupled together such that the currents flowing through the 1st and 2nd frequency sections substantially cancel and the current flowing through the 1st and 2nd radiation sections are substantially cumulative for a ½ wavelength antenna. For a full wavelength antenna, 1st and 2nd dipole antenna sections are electrically coupled together such that the currents flowing through the 1st and 2nd frequency sections are substantially cumulative and the current flowing through the 1st and 2nd radiation sections substantially cancel.

摘要： An analog-to-digital conversion scheme allows the conversion of a small dynamic range analog signal into a floating-point, digital representation with a larger dynamic range. A montonically changing analog signal is reset to a reference value at time t=0. The analog signal is then sub-converted by an analog-to-digital converter with maximum input signal level Ss to corresponding digital representations at several sub-conversion times t=T2>T1, t=T3>T2, . . . t=TM>TM−1, where TM≦T. These digital representations are then suitably combined to produce a cumulative, floating-point digital representation which accurately represents the analog signal even if the analog signal has a value greater than Ss at time t=T.

摘要： A method for simultaneously performing bit serial analog to digital conversion (ADC) for a potentially very large number of signals is described. The method is ideally suited for performing on chip ADC in area image sensors. In one embodiment, to achieve N-bit precision, the method employs a one-bit comparator per channel (or set of multiplexed channels) and an N-bit DAC. To achieve N bits of precision, 2.sup.N -1 comparisons are sequentially performed. Each comparison is performed by first setting the DAC output to the desired value and then simultaneously comparing each of the pixel values to that value. If a pixel value is greater than the DAC output value, its comparator outputs a one, otherwise it outputs a zero. By appropriately choosing the sequence of comparison values, the pixel values are sequentially generated. In another embodiment, the DAC is omitted and a continuous ramp signal is generated for comparison with the analog input.
摘要翻译：描述了用于同时执行位串行模数转换（ADC）用于潜在非常大量信号的方法。该方法非常适合在区域图像传感器中执行片上ADC。在一个实施例中，为了实现N位精度，该方法采用每通道（或多路复用通道组）和N位DAC的一位比较器。为了实现N位精度，依次执行2N-1比较。通过首先将DAC输出设置为期望值，然后同时将每个像素值与该值进行比较来执行每个比较。如果像素值大于DAC输出值，则其比较器输出1，否则输出零。通过适当地选择比较值的顺序，依次生成像素值。在另一个实施例中，省略了DAC，并且生成连续的斜坡信号以与模拟输入进行比较。

摘要： A portable unit with an endfire antenna and operating at 60 GHz makes an optimum communication channel with an endfire antenna in an array of antennas distributed over the area of a ceiling. The portable unit is pointed towards the ceiling and the system controlling the ceiling units selects and adjusts the positioning of an endfire antenna mounted on a 3-D adjustable rotatable unit. Several transceivers can be mounted together, offset from one another, to provide a wide coverage in both azimuth direction and elevation direction. These units can be rigidly mounted as an array in a ceiling apparatus. The system controlling the ceiling array selects one of the transceivers in one of the units to make the optimum communication channel to the portable unit. The system includes the integration of power management features by switching between Wi-Fi in favor of the 60 GHz channel.

The patterned organic mask is treated to reduce very low frequency line width roughness of the patterned organic mask, comprising flowing a treatment gas comprising H2, wherein the treatment gas has a flow rate and H2 has a flow rate that is at least 50% of the flow rate of the treatment gas, forming a plasma from the treatment gas, and stopping the flow of the treatment gas. The etch layer is etched through the treated patterned organic mask with the reduced very low LWR.
