Abstract: A level shifter circuit suitable for high voltage applications with shoot-through current isolation is presented. The level shifter receives a first enable signal and receives an input voltage at a first node and supplies an output voltage at a second node.

The level shifting circuit includes a depletion type NMOS transistor, having a gate connected to the output node, and a PMOS transistor, having a gate connected to the first enable signal. It also includes a first resistive element that is distinct from the NMOS and PMOS transistors. The NMOS transistor, the PMOS transistor and the first resistive elements are connected in series between the first and second nodes, with the NMOS transistor being connected to the first node.

Abstract: This disclosure describes a system in which individual employee records can be updated across multiple services by an administrator at the interface to a particular service. Multiple services may be provided with this capability. This will eliminate the need in the current art for a central directory that contains a service description that will be common across all services. The technology eliminates the need for the development of this directory and the training of administrators in its interface. Administrators may utilize their training in one service interface to update records across multiple services. This will enable the more rapid development of solutions utilizing services from multiple vendors. Administrators need not be trained on interfaces for all services but can apply routine global updates from a convenient and familiar interface.
