摘要:
An integrated circuit that includes a substrate having a shape memory material (SMM), the SMM is in a first deformed state and has a first crystallography structure and a first configuration, the SMM is able to be deformed from a first configuration to a second configuration, the SMM changes to a second crystallography structure and deforms back to the first configuration upon receiving energy, the SMM returns to the first crystallography structure upon receiving a different amount of energy; and an electronic component attached to substrate. In other forms, the SMM is in a first deformed state and has a first polymeric conformation and a first configuration, the SMM changes from a first polymeric conformation to a second polymeric conformation and be deformed from a first configuration to a second configuration, the SMM changes returns to the first polymeric conformation and deforms back to the first configuration upon receiving energy.

The signal device, secured to the door of a rural mailbox, shows that mail has been received. The device operates by opening a shutter to display the message, "MAIL," when the mail carrier opens the mailbox door. It operates by gravity and latches magnetically. The shutter opens as a venetian blind when the weighted screen falls forward. The signal device is reset by pushing the reset tab. The device returns to the closed position by gravity. In the closed position the message, "NO MAIL," printed on the shutter, is displayed. Moving parts are contained in a weather-proof box with a transparent window. The messages, "MAIL," or "NO MAIL" are visible through the transparent window.

A transparent plate with fiducials for aligning and placing of dies on a panel with a high degree of accuracy is disclosed. The locations of the fiducials correspond to desired die locations. The transparent plate is arranged beneath the panel, with the fiducials aligned with cavities formed in the panel. The cavities have transparent bottoms. A die alignment mark on a die residing over the panel is used to establish the position of the die. Imaging a fiducial associated with a cavity is used to center the die with respect to the cavity. Accurate placement of the fiducials is accomplished by electron-beam lithography.
