Abstract: A transfer belt apparatus, system and method are provided to prevent image blooming. For example, an ink jet printing apparatus may include a grounded print head, a counter-electrode opposite the ground print head, and a bi-layer transfer belt provided between a print head and a counter-electrode and at least partially supported by two or more transfer bias rollers. A method may include applying a voltage between a print head and a counter-electrode to accelerate ink drops coming out of the print head toward a transfer belt, and evacuating charge accumulated on the transfer belt with a time constant smaller than a drop ejection frequency of the print head.

Abstract: A data transmission interconnect assembly capable of transmission speeds in excess of 40 Gbps in which, for example, a line-card is detachably coupled to a backplane using flexible flat cables that are bent to provide a continuous, smooth curve between the connected boards, and connected by a connection apparatus that employs cable-to-cable interface members that are transparent to the transmitted signal waves. Microspring interface members are formed on the contact structure pressed against the cables to provide interface arrangements that are smaller than a wavelength of the transmitted signal. A connector apparatus uses a cam mechanism to align the cables, and then to press the contact structure, having the microspring interface members formed thereon, against the cables. An alterative contact structure uses anisotropic conductive film.

Abstract: In accordance with one embodiment of the present application, a piezoelectric diaphragm structure includes a diaphragm, with a piezoelectric material located on the diaphragm. The piezoelectric material is being poled in a radial direction to the piezoelectric material, wherein the poling direction is in-plane with the piezoelectric material. An inter-digitated electrode grid is positioned on a first surface of the piezoelectric material, the inter-digitated electrode grid including a plurality of electrodes configured to selectively receive positive and negative voltage. The application of the positive and negative voltages generate electric fields in the piezoelectric material, at least a portion of which are in-plane with the piezoelectric material, resulting in an actuation of the piezoelectric material, causing a length change of the piezoelectric material in the Radial direction. In accordance with another embodiment of the present application, provided is a method of actuating a piezoelectric diaphragm structure, including poling a piezoelectric material in a radial direction of the piezoelectric material, wherein the poling direction is in-plane with the piezoelectric material. The piezoelectric material is located in operative contact with the diaphragm, and an electrode arrangement located on a surface of the piezoelectric material is selectively supplied with voltages generating electric fields. The generated electric fields are at least partially in the same plane as the poling direction, resulting in a d33 mode of actuation of the piezoelectric material, causing a length change of the piezoelectric material in the Radial direction.

Abstract: A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. The microdisk laser is coated with a biological or chemical recognition element, which binds preferentially with a target analyte. Because the recognition element and the target analyte adhere to the sidewall surface of the microdisk laser, they increase the effective diameter of the laser, which shifts the output wavelength by a detectable amount. The presence of a wavelength shift indicates the presence of the target analyte, and the magnitude of the wavelength shift corresponds to the mass load of the target analyte on the sidewall surface of the microdisk laser.
