A mortise latch and vertical rod exit device latches at a center point between two doors and at top points between each door and the door frame. Optionally vertical rods may also be used to latch at bottom points between the doors and the floor. The latch includes an active and a passive latch mechanism operated by corresponding operating mechanisms. The mortise latch mechanisms cooperatively interact so that either door may be opened first, and either door may be closed first, without regard to the position of the other door. The active mortise latch mechanism includes a latch bolt and an activation bolt arranged so that one bolt is retracted when the other is extended, except when the doors are being opened or closed, when both bolts are retracted. The active mortise latch mechanism automatically retracts the latch bolt when the doors are not aligned and automatically extends the latch bolt when the doors are aligned. The passive mortise latch mechanism ejects the latch bolt as needed to allow the passive door to be opened first.

A computer peripheral device suitable for operation with a Peripheral Component Interconnect (PCI) Bus or the like, has the ability to "wakeup" the bus from a cold state (e.g., D3cold) without the need to supply auxiliary power (e.g., 3.3 volts) to the entire device during the cold state. A modem in the preferred embodiment (although the invention is applicable to other peripheral devices), the device latches device status information from the main circuitry of the device (operating on 5 volts, for example) into a "keep alive" circuit connected to the auxiliary power supply upon the falling edge of a PCI reset signal (RST#). Additionally, the auxiliary power supply also powers a ring detect circuit for the detection of an incoming telephone call, which incoming call triggers a Power Management Event (PME#) signal for changing the state of the bus to an active state. Further, the auxiliary power supply powers a RST# detection circuit for indicating that a change in the power state of the bus is imminent.

A processor retainer assembly prevents inadvertent removal of a processor from a circuit board socket by forces exerted on an information handling system that are translated from a heat sink to the processor by the coupling of thermal grease between the heat sink and the processor. A retention frame couples to a motherboard around the processor socket to support movement of the processor retainer between open and closed positions. A securing device hinge rotationally couples the processor retainer to the retention frame and a securing device latch locks the processor retainer in the closed position to restrict movement of the processor from the socket. A heat sink contacts the processor through an opening in the processor retainer. Heat sink supports extending from the retention frame engage the heat sink so that a single processor retainer assembly retains the processor in the socket and the heat sink proximate to the processor.

A representative embodiment of the invention provides a MEMS-based safety and arming (S&A) device having a shuttle movably connected to a frame by one or more bowed springs. The device has an electrical path adapted to electrically connect the frame and a contact pad. In the initial state, the electrical path has an electrical break.

A post-erase channel clearing procedure for double well, floating gate, non-volatile memory cells. The channel is cleared of charged particles coming from the floating gate after an erase operation in two steps. In the first step the charged particles are pushed into an upper substrate well below the floating gate but not allowed into a deeper well of opposite conductivity type relative to the upper well. After a brief time, T, the charged particles are pushed by a bias voltage into the deeper well from the upper well. This two step clearing procedure avoids device latchup that might occur otherwise.
