Abstract: A precursor for a Radio Frequency Identification (RFID) tag includes a conductive lead frame with at least three segments, an RFID Integrated Circuit (IC) with at least two antenna terminals, and at least two jumpers. The RFID IC is mounted on at least one of the segments. The antenna terminals are electrically coupled to at least two of the segments, and the jumpers electrically couple the segments such that the coupled segments form a two-turn coil between the antenna terminals of the RFID IC.

Abstract: Microcircuits may include polysilicon features that are vulnerable to defects due to undesirable phenomena during manufacturing processes such as, inter alia, over-etching. The same phenomena that may cause defects can be exploited to automatically isolate the affected circuit and thus limit the harm caused by defects or incipient defects.

Abstract: Methods are provided, and devices made by such methods. One of the methods includes procuring a semiconductor wafer, processing the wafer to form a plurality of circuits on a top side, forming trenches on the top side between the adjacent circuits, forming a trench passivation layer on side walls of the trenches, forming conductive bumps on the top side of the wafer; and removing material from the bottom side to thin the wafer, and eventually separate the wafer along the trenches into dies, where each die includes only one of the circuits.

Abstract: A programmable microcomputer controlled alarm clock has a multi-key input keyboard for setting the time of day, the month and date, and the alarm times of two or more independent alarms. Each alarm may be set to generate an alarm signal at a selected time on each day of two to six consecutive days of a seven-day period, the alarm sequence being automatically repeated each following seven-day period. In the normal operational mode, time of day is displayed until a month-and-date switch, an alarm-period or doze switch, or an alarm-enabling switch is actuated to display the respective date and alarm time. After the particular switch is actuated and the appropriate time information displayed, the clock returns to display time of day within several seconds.

Abstract: An alarm sounder for use with solid state integrated clock circuits employs an amplifying transistor controlled by the clock alarm output signal that contains an A.C. component to control the current through a coil, the core laminations of which magnetically actuate a metal reed that is audibly vibrated by utilizing a spring against the core and/or an adjacent member at the frequency of the A.C. component.
