    Abstract: An optically triggered silicon controlled rectifier (SCR) circuit (20) has a number of semiconductor layers diffused into an N- substrate (21). The layers form an SCR (50) having a P+ anode region (25), a P+ gate region (24), and an N+ cathode region (27). An adjustable base-shunt resistance, in the form of a P- channel depletion mode MOSFET (Q3), connects between the SCR gate region and the cathode region. The MOSFET includes a MOSFET gate region (35), a P+ drain region (24), a P-- channel (26), and a P+ source region (23). The substrate also accommodates a PN photodiode (22, D1) which connects to the MOSFET gate region for switching the MOSFET on and off in response to incident optical radiation (L) thereon. The SCR gate region also comprises photosensitive material. When sufficient optical radiation illuminates the photodiode and the SCR gate region, the MOSFET is turned off and the SCR is triggered, permitting anode-to-cathode current to flow. When insufficient optical radiation is present, the MOSFET is turned on and provides a low-resistance shunt path which prevents the SCR gate region from triggering the SCR.

    Abstract: An enclosure for an energy monitoring current transformer includes upper housing that houses an upper transformer core section. Lower housing houses a transformer coil and a lower transformer core section. When the enclosure is assembled there is an overlap between the cap for the lower housing and the lower housing that lengthens a creepage path from the upper transformer core to the external surface of the enclosure.

    Abstract: An integrated circuit (IC) (20) is formed on a semiconductor substrate (21). The IC has a PN junction (28) and a graded junction termination (27). A reverse field plate (31) is mounted adjacent the junction termination. One end of the field plate is mounted on and electrically connected to the substrate; the remainder of the field plate extends over a passivating oxide layer (30) which covers the substrate surface (29) adjacent the junction termination. The field plate provides a common potential surface which maintains a fixed potential on the substrate surface at the junction termination.

    Abstract: An optically-triggered silicon controlled rectifier (SCR) (21) having a number of semiconductor layers (23, 24, 31) diffused into an N type substrate (22). Specifically, the SCR is formed by diffusing a first P+ layer (23) into an upper surface of the substrate. Then, an N+ layer (24) is diffused into a portion of an upper surface of the first P+ layer. An oxide layer (25) which is permeable to optical radiation is formed on the first P+ layer. A conductive cathode terminal (26) is then deposited on the N+ layer. Therefore, a trench (30) is etched in the lower surface of the substrate. The trench is defined by a depth and a surface. A second P+ layer (31) is diffused into the surface of the trench. The depth of the trench substantially defines a spacing between the first and second P+ layers. The chip is soldered onto a pedestal (33) formed on a lead frame (34). The solder is deposited in the trench and contacts the second P+ layer to form an anode terminal (36). The pedestal may be formed by either etching or stamping a depression (35) in the lead frame.

    Abstract: Embodiments provide for extending the architecture of a legacy messaging system that otherwise communicates message rules to a client as rows in a rule table. Due to architectural limitations of some messaging systems, rules larger than a specified size are prevented from being streamed between a server and a client. Example embodiments provides for extended rules that represent a combination of conditions, actions or exceptions to be performed on messages and are created by a client as message objects. Because they are created by a client as message objects, rather than rows on a table, the extended rules are allowed to be streamed between the client and server, thus extending the architecture of a legacy messaging system. The client also sets a property value on the message object created, thereby allowing the server to identify the message object as including the extended rule. The system, however, still supports legacy clients.
