    • One example embodiment relates to a method that comprises receiving a request from a user via a computer network to list of one or more items on the computer network that are part of a garage sale; and providing advertising to the user that indicates where the items in the garage sale may be found using the computer network. Another example embodiment relates to a system that comprises a communication module connected to a computer network; the communication module being adapted to receive a request from a user to list items that are part a garage sale; a multiple listing engine that receives data relating to the items from the user and lists the items for sale on the communication network; and an advertisement that includes information as to where buyers can view the items that are part of the garage sale on the communication network.

    • Apparatus for measuring a pressure differential in a fluid carrying conduit characterized by a digital representation of the rate of fluid flow and a high degree of accuracy is disclosed. The sensor portion of the apparatus includes two identical electrically driven piezoelectric crystals. One crystal provides a series of pulses at its resonant frequency for use as a reference signal. The second crystal provides a series of pulses at a frequency which is inversely related to a force applied thereto. The sensor further includes two (minimally) arcuately curved stainless steel sealing diaphragms urged in opposing directions by two pressures acting in opposing directions. The movement of the two diaphragms, which are rigidly connected to one another, and which is directly related to the difference in magnitude of the two pressures, is used to apply the force to the second crystal. The pulse trains provided by the first and second crystals are transmitted to a modulator which provides, as its output, a series of pulses at a frequency which is equal to the difference of the frequencies provided by the first and second crystals, this last frequency, which is subsequently provided to utilization apparatus, therefore being directly related to the difference between the first and second pressures.
    • 公开了用于测量流体输送管道中的压力差的装置,其特征在于流体流动速率的数字表示和高精确度。 该装置的传感器部分包括两个相同的电驱动压电晶体。 一个晶体以其谐振频率提供一系列脉冲用作参考信号。 第二晶体以与施加到其上的力成反比的频率提供一系列脉冲。 传感器还包括两个(最低限度)弧形不锈钢密封隔膜,通过两个相反方向作用的压力在相反方向上推动。 使用两个彼此刚性连接并且与两个压力的大小差异直接相关的两个膜片的移动来将力施加到第二个晶体。 由第一和第二晶体提供的脉冲串被传送到调制器,该调制器以等于由第一和第二晶体提供的频率的差的频率提供一系列脉冲作为其输出,该最后频率, 随后将其提供给利用装置,因此与第一和第二压力之间的差异直接相关。
