Abstract: A bonded assembly includes an interposer; a semiconductor die that is attached to the interposer and including a planar horizontal bottom surface and a contoured sidewall; a high bandwidth memory (HBM) die that is attached to the interposer; and a dielectric material portion contacting the semiconductor die and the interposer. The contoured sidewall includes a vertical sidewall segment and a non-horizontal, non-vertical surface segment that is adjoined to a bottom edge of the vertical sidewall segment and is adjoined to an edge of the planar horizontal bottom surface of the semiconductor die. The vertical sidewall segment and the non-horizontal, non-vertical surface segment are in contact with the dielectric material portion. The contoured sidewall may provide a variable lateral spacing from the HBM die to reduce local stress in a portion of the HBM die that is proximal to the interposer.

Abstract: A microphone device including a first sound receiving module, a second sound receiving module and a sound collecting trough is provided. The first sound receiving module receives a sound signal to output a first electronic signal. The second sound receiving module receives the sound signal to output a second electronic signal. The first sound receiving module is coupled to the second sound receiving module, and the phase of the first electronic signal and the phase of the second electronic signal are inverse to each other. A distance between the first sound receiving module and the sound collecting trough is smaller than a distance between the second sound receiving module and the sound collecting trough, and another sound signal is transferred to the first sound receiving module through the sound collecting trough.

Abstract: A rotary combustion engine system is provided with compression unit and expansions unit offset which communicate through a transfer port. Each unit defines a toroidal chamber extending annularly about a central cavity, and a plurality of curved pistons displaced within the toroidal chamber to variably form a plurality of sub-chambers therein. A rotor member in each unit is eccentrically coupled to a mechanical member and linked by a plurality of swing rod members to the curved pistons. The curved pistons of the expansion unit are advanced by recursive combustion within sub-chambers defined therebetween, to drive angular displacement of the rotor member. The rotor member in the compression unit is angularly displaced with the mechanical member to incrementally advance the unit's curved pistons for recursive compression of air within sub-chambers defined therebetween. The compressed air is recursively passed through the transfer port to the sub-chambers of the expansion unit for combustion.

Abstract: The invention provides an office machine which includes a housing, a transparent platform, and an aligning device. The aligning device includes a casing, a dam member, and at least one resilient member. The dam member has a main body and an extension portion. A gap exists between the extension portion and the platform. If the thickness of an object is less than the gap, the object, placed on the platform, is inserted into the gap to make an edge of the object align with an aligning edge of the casing.

The second user interface is connected with the finance agency authorization end through a second communication path. The method for verifying personal identity on internet comprises transferring a verifying code to a user through a communication path and checking the verifying code entered by the user from another communication path.

Abstract: The present invention involves a porous rigid filter including a plurality of concentric filtration elements having internal flow passages and forming external flow passages there between. The present invention also involves a pressure vessel containing the filter for the removal of particulates from high pressure particulate containing gases, and further involves a method for using the filter to remove such particulates. The present filter has the advantage of requiring fewer filter elements due to the high surface area-to-volume ratio provided by the filter, requires a reduced pressure vessel size, and exhibits enhanced mechanical design properties, improved cleaning properties, configuration options, modularity and ease of fabrication.
