  • Patent number: 11942148
    Abstract: Crossbar arrays perform analog vector-matrix multiplication naturally and provide a building block for modern computing systems. Specialized mixed-signal interface circuits are interfaced with the rows and columns of the crossbar arrays. During operation, the mixed-signal interface circuits provide high voltages for write operations and low voltages for read operations. This disclosure presents improved designs for the mixed-signal interface circuits which minimize the number of switches as well as the number level shifters.

  • Patent number: 7553199
    Abstract: A modular terminal block for connecting leads or wires to an electrical body includes a module stack of side-by-side module assemblies and an alignment plate. Each module assembly includes a housing, a number of conductors extending from the housing, and a cover member to cover the conductors. The alignment plate accurately positions the conductors despite variations in housing dimension due to manufacturing tolerances. The housing includes walls supported on both sides when forming part of the module stack. The walls resist deflection of the conductors during installation of the alignment plate and electrical body. Each cover member engages and is held closed by a conductor extending from the housing.

  • Patent number: 7056160
    Abstract: A hybrid electrical connector includes both signal and power contacts in the same connector housing. The housing includes a plurality of axially extending passageways for receipt of the signal contacts and a plurality of axially extending cavities for receipt of the power contacts. The connector housing further includes a plurality of transversely extending slots extending through the connector housing intersecting with individual power contact cavities. Moreover, the housing includes a protrusion extending across the lower surface thereof. A Y-shaped terminal retaining member is insertable in the slots and is resiliently held in place in the slots. The power terminals include an opening therethrough forming a locking shoulder for receipt of the transversely extending locking member. In addition, the power terminals include notches for mating with the protrusion. The combination of the notches and the protrusion ensure the terminal is properly positioned within the housing.

  • Publication number: 20050009380
    Abstract: A socket connector including a socket base having a slot oriented at a first angle with respect to a bottom surface of the socket base. The socket connector also includes a contact having a base beam and a retention portion. The retention portion forms an initial angle with the base beam before the contact is assembled with the socket base that differs from the first angle. The socket base receives the contact with the retention portion held in the slot such that an angle between the base beam and the retention portion is changed from the initial angle.
