Abstract: Electrical connector systems and methods create an electrical connection between a flexible circuit (FC) and a metal terminal of another connector. A reliable electrical connection is achieved with a low-cost tin contact plating, by an automatic FC to metal terminal wiping action with contact force, during the connector to FC assembly process. The connector to FC assembly process is also well suited for automated robotic assembly, which can save costs compared to manual assembly/installation.

Abstract: Magazine block device for firearm dry fire practice which allows a user to practice proper firearm handling skills without expending ammunition, including recocking and actuating the firearm slide without pressing the slide lock release. In an aspect, a magazine block device is provided having a bullet-shaped body, two upper ridges forming a longitudinal channel through which the firearm breach face loading tab may pass without dislodging the magazine block device, and an offset lower ridge. The lower ridge is configured to evenly force a magazine follower down a sufficient distance to prevent actuation of the firearm slide lock. This allows dry fire practice of pulling the slide. Several other features include ridges to assist a user to remove and load the block device in and out of a magazine, as well as a pocket to mechanically remove same.

Abstract: An on-line database updating network system and method using object-oriented programming to build a program of discrete blocks, with each block being separately accessible, modifiable, and replaceable. The system includes a user terminal, a host terminal, and a communications channel. Origin dates of user module blocks of information stored in the user terminal are compared, over the communications channel, with origin dates of corresponding host module blocks of information stored in the host terminal. Host module blocks having origin dates more recent than corresponding user module blocks are downloaded as updated blocks over the communications channel to the user terminal. The downloaded updated blocks are then used to update the relevant user module blocks of information. Alternate host terminals may also be accessed by the user terminal, and updated alternate host module blocks of information may be downloaded to the user terminal.

The system includes a user terminal, a host terminal, and a communications channel. Origin dates of user module blocks of information stored in the user terminal are compared, over the communications channel, with origin dates of corresponding host module blocks of information stored in the host terminal. Host module blocks having origin dates more recent than corresponding user module blocks are downloaded as updated blocks over the communications channel to the user terminal. The downloaded updated blocks are then used to update the relevant user module blocks of information. Alternate host terminals may also be accessed by the user terminal, and updated alternate host module blocks of information may be downloaded to the user terminal.

The source and the drain of the pull-up output transistor are formed in a common bulk region of the substrate. A bulk potential control circuit for controlling the voltage of the bulk region, a resistive element and a gate drive control circuit are also formed in the silicon substrate. A layer of interconnect formed over a top surface of the silicon substrate may selectively couple into the output driver circuit one or more of the resistive element between a source of the pull-down output transistor and a reference voltage source, the bulk potential control circuit to control the voltage of the bulk region of the silicon substrate, and the gate drive control circuit to control the rate of change of voltage on the gate of the pull-down transistor as a function of the voltage on this gate.

In another aspect of the invention, a resistive element is provided between the source of the pulldown FET and a ground voltage supply line.

Abstract: A leadframe for use in an integrated circuit package is described. The leadframe comprises a plurality of electrically conductive leads, a die attach pad, and an electrically conductive ring or rings formed generally around the circumference of the die attach pad and between the die attach pad and leads. In one embodiment, at least one of the leads is formed integrally with each ring. The die attach pad may also be formed integrally with one or more leads. In another embodiment, the ring or rings are formed so that they are electrically isolated from the die attach pad, and the die attach pad, leads, and ring or rings are all formed in substantially the same plane. In some embodiments, the ring or rings are broken into electrically isolated sections. Each of the ring sections (and die attach pad, if appropriate) may be electrically connected to a voltage source outside the integrated circuit package (e.g., a power supply or ground).
