This invention discloses a one-time programmable (OTP) memory cell. The OTP memory cell includes a dielectric layer disposed between two conductive polysilicon segments wherein the dielectric layer is ready to change from a non-conductive state to a conductive state through an induced voltage breakdown. In a preferred embodiment, one of the conductive polysilicon segments further includes an etch undercut configuration for conveniently inducing the voltage breakdown in the dielectric layer. In a preferred embodiment, the dielectric layer is further formed as sidewalls covering the edges and corners of a first polysilicon segments to conveniently induce a voltage breakdown in the dielectric layer by the edge and corner electrical field effects.

A coil arrangement that has a primary and a secondary C-shaped core, each C-shaped core having an elongated base and two shorter legs at the ends of the base, a winding being applied to each base and the ends of the windings being electrically connected at the legs of the cores and the cores being arranged with respect to each other such that the legs of the two cores are located opposite each other.

A vacuum apparatus rotatable about an axis through a filter screen for continually removing contaminants, which utilizes an asymmetrical vacuum arm supported by a center hub, and large longitudinally extending asymmetrical vacuum orifices in portions of the arm on opposite sides of the hub, operable for removing large elements of debris, trash and the like from the screen. One of the arm portions cleans a radial outer region of the screen, and the other cleans an inner region, the arm portions being generally even in mass for balance. A knife disposed on the screen cleans and cooperates with a brush on the arm for breaking up larger elements of trash. The arm is also manually removable via a snap together vacuum seal joint, for service and cleaning.

The invention relates to a porous scaffold structure, in particular to a low-modulus medical implant porous scaffold structure, and belongs to the field of medical implant material. The low-modulus medical implant porous scaffold structure is formed by sequentially overlaying a plurality of basic units in three-dimensional space along three-dimensional directions, wherein each basic unit comprises a quadruple prism body or a hexagonal prism body with a center communicating hole, formed by four or six side walls; each side wall adopts an X-shaped framework structure formed by intersecting two square ribs; the center communicating holes of each two adjacent basic units along the axis of the quadruple prism body or the hexagonal prism body are mutually communicated. The structure not only reduces the implant modulus, ensures that the implant modulus is perfectly matched with the implant strength, improves the configuration of a traditional metal implant, optimizes the mechanical distribution and reduces the stress shielding effect, but also has a regular through hole structures, is beneficial to the ingrowth of bone tissue, and can also enhance the mutual locking between the bone tissue and the implant, and shorten the rehabilitation time of patients.
