摘要： A method of ejecting liquid includes providing a liquid dispenser including a substrate and a diverter member. A first portion of the substrate defines a liquid dispensing channel including an outlet opening and a second portion of the substrate defines an outer boundary of a cavity. Other portions of the substrate define a liquid supply channel and a liquid return channel. The diverter member includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the 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 MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member. A second portion of the compliant membrane is anchored to the substrate such that the compliant membrane forms a portion of a wall of the liquid dispensing channel. The wall is positioned opposite the outlet opening. A continuous flow of liquid is provided from a liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply. The diverter member is selectively actuated to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel when drop ejection is desired.

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.
