A programmable variable depth and width random-access memory circuit contains rows and columns of memory cells in a RAM array 148 for storing data. A row decoder 190 is used to address individual rows of the memory cells. Column address circuitry receives a column address signal 168 and a width and depth selection signal 156. A column decoder 170 within the column address circuitry addresses one o...

A slider (16A) of a magnetic head (10A) is provided with first (12) and second (14) magnetic head parts, and a central groove (18A) so that first (20A) and second (22A) air bearing surfaces separate from each other are formed. An air flow produced between the air bearing surfaces, and a magnetic disk creates an elevating force. A width (A1) of the first air bearing surface at the leading edge is c...

A method and equipment for using two SIM cards with the same MSISDN number in a mobile communication system. To at least one subscriber identifier are allocated at least two identity modules (SIM), of which only one at a time can be registered as active. In connection with location updating it is checked whether the location updating relates to a subscriber identifier to which at least two identit...

An articulating prosthesis includes a cup having a shell and a liner and at least one resilient locking element. The shell has a spherical outer surface that may be adapted to articulate with an acetabulum and the liner has a spherical inner surface that forms an articulation surface for the spherical head of a stem member.
