摘要： Operating an ultrasonic transmitter and receiver includes providing a MEMS composite transducer. The MEMS composite transducer includes a substrate. Portions of the substrate define an outer boundary of a cavity. A first MEMS transducing member includes a first size. A first portion of the first MEMS transducing member is anchored to the substrate. A second portion of the first MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A second MEMS transducing member includes a second size smaller than the first size of the first MEMS transducing member. A first portion of the second MEMS transducing member is anchored to the substrate. A second portion of the second MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A compliant membrane is positioned in contact with the first and second MEMS transducing members. A first portion of the compliant membrane covers the first and second MEMS transducing members. A second portion of the compliant membrane is anchored to the substrate. Electrical pulses are sent to the first MEMS transducing member which causes the first MEMS transducing member and the compliant membrane to vibrate. The vibrations of the first MEMS transducing member and the compliant membrane are transmitted to an object. Echo signals are received from the object. The received echo signals are converted into electrical signals by the second MEMS transducing member.

摘要： An internal filter includes a lower substrate and an upper substrate. Fluid passages are formed by etching grooves into the surface(s) of the upper and/or lower substrates, and/or in one or more intermediate layers. The filter pores extending between the fluid passages are formed by etching second grooves that fluidly connect the fluid passages. Two or more sets of the one or two intermediate layers can be implemented to provide additional filter passages and/or pores. Each set can be connected to a separate fluid source and/or a separate microfluidic device. In another internal filter, the inlet and outlet passages and the filter pores are formed on the same upper or lower substrate. The inlet and outlet passages are partially formed in a first step. In a second step, the inlet and outlet passages are completed at the same time that the filter pores are formed.

摘要： The present invention relates to a method that enables image quality of a printed image to be maintained by reducing unintended variations in drop volume, through the adjustment of ink drop ejecting conditions depending on the amount of ink remaining in an ink tank chamber or reservoir, and/or the ink demand for printing an image. The method of printing of the present invention comprises: providing a printhead in fluid communication with an ink chamber or reservoir; detecting at least one parameter related to an amount of negative pressure provided to the printhead; and adjusting an ink drop ejecting condition of the printhead as a function of the parameter so that an amount of variation in size of ejected ink drop is reduced.
