Abstract: A flip chip micromirror assembly comprising a micromirror chip that is flip chip mounted onto the circuit board via a bonding layer. The micromirror chip has a micromirror layer in which a micromirror is formed. The micromirror chip has a flip chip surface facing the electrode surface of the circuit board. The bonding layer includes conductive region(s) that electrically couples corresponding board electrodes with corresponding chip electrodes. However, the bonding layer is not interposed between the electrode surface of the circuit board and the micromirror itself. In other words, the bonding layer spaces the micromirror chip from the circuit board, and provides a gap underneath the micromirror between the micromirror chip and the circuit board. This gap is of sufficient thickness that the micromirror can be actuated with full movement without being mechanically obstructed by the circuit board.

Abstract: A piezoelectric MEMS scanning mirror system is provided. In particular, the efficiency and life of the system are improved by use of new bonding methods. Mechanical and electrical connections between the actuator frame of a piezoelectric MEMS scanning mirror system and the piezoelectric actuators in the system may be created using an anisotropic conductive adhesive. An anisotropic conductive adhesive only conducts electricity across the bond line between a lower portion of the piezoelectric actuator and a top of the metal frame. One way this is done is to provide a sparse loading of conductive particles. When the piezoelectric element is compressed against the frame, the conductive particles only form a conductive path across the bond line. Grit blasting, sanding, or chemical etching may be used to roughen the metal surface prior to bonding. A surface roughness between 2 RMS and 6 RMS may be created on the metal frame.

Abstract: A micro electro mechanical system is provided. The micro electro mechanical system includes a first part bonded to a second part by a structural adhesive interface. The structural adhesive interface includes a conductive structural adhesive portion, and a non-conductive structural adhesive portion at least partially surrounding the conductive structural adhesive portion. The conductive structural adhesive portion and the non-conductive structural adhesive portion have a thixotropy index greater than one.

Abstract: The present invention relates to an absorbent article for managing bodily fluids, comprising a high coefficient of friction (“COF”) backsheet and at least one tape tab extending therefrom. The tape tab comprises a minimum amount of pressure sensitive adhesive sufficient to maintain the position of the article when a user's undergarments are away from her body. When the undergarments are near her body, the high COF backsheet acts as the predominant means for maintaining the position of the article due to normal forces exerted by the user's body and undergarments. When the user wants to remove the article from her undergarments, the tape tab provides additional advantages. The user may grasp the tape tab itself for removing the article as an alternative to grasping a portion of the soiled article. In addition the soiled article may be folded or rolled up, and then held in that configuration with the tape tab, for convenient and discreet disposal.

Abstract: The present invention relates to a method of applying a hot melt adhesive to an absorbent article, such that the article has low autoadhesion, yet maintains excellent attachment properties during use in a consumer's undergarments. This is achieved by selecting the rheological properties of the adhesive and the mechanical properties of the substrate being coated. The adhesive is directly applied to a backsheet layer outer surface, wherein the adhesive has a viscosity of less than about 10,000 centipoise at a temperature of about 130 to about 177 degrees Celsius. The backsheet layer has a tensile strength of at least 5 Newtons per 25 millimeter width of material.

Abstract: Absorbent articles having a top odor absorbing layer, a middle moisture absorbing layer, and a bottom non-skid layer are disclosed. The bottom non-skid layer has a static coefficient of friction of greater than 1.0 and a dynamic coefficient of friction of greater than 0.9. The articles are particularly useful for disposable shoe inserts.
