Abstract: Rewritable signs (100, 1300) that include bistable cholesteric liquid crystal layers (102, 1402, 1404, 1406) are provided. According to one embodiment a rewritable sign (100) is devoid of circuitry for establishing electric fields in localize regions for writing information to the rewritable sign (100), and is consequently inexpensive. In the latter embodiment, a separate information writer (400) that includes an array of pixel electrodes (404) that is driven by an active matrix (602) is used to write information on the rewritable sign. According to another embodiment a rewritable sign (1300) includes three cholesteric liquid layers (1402, 1404, 1406) each of which reflects a different primary color. The three cholesteric liquid crystal layers (1402, 1404, 1406) are interleaved with sets of conductive lines (1316, 1320, 1322, 1324) that are used to apply signals to the cholesteric liquid crystal layers (1402, 1404, 1406) for the purpose of writing information.

Abstract: A communication device is designed to contain the lowest possible level of toxic or hazardous materials, so that when it is eventually disposed of, it will not harm the environment and can be safely recycled. Each component A.sub.1, A.sub.2, . . . , A.sub.n in the communication device has a calculated Component Toxicity Index value. A Product Toxicity Index for the entire communication device is calculated by summing the individual Component Toxicity Index values. The desired outcome is a communication device having a Product Toxicity Index less than or equal to 100. The resulting communication device is referred to as "environmentally friendly". The communication device may be a two-way radio (10), and some of the components are a radio transmitter (12), a radio receiver (14), an antenna (16), an amplifier (18), a battery (20) and a housing (22).

Abstract: An improved leadless semiconductor device package consists of a molded plastic carrier (30) with a plurality of C5 bumps (52) integrally molded into the bottom side of the carrier. The bumps are made of the same plastic as the carrier and are monolithic to the carrier. The C5 bumps are coated with a solderable material (50) so that they can be connected to pads on a PCB with solder paste. The top side of the plastic carrier has a metallization pattern containing a plurality of bond pads (44) that correspond to pads on the semiconductor die, and the bond pads are electrically connected to the C5 bumps by an electrically conductive structure. A semiconductor die (38) is mounted on the carrier top side and electrically connected to the plurality of bond pads, either by wire bonds (54) or by flip chip bonding. C4 bumps (70) can also be molded into the carrier for flip chip attachment.
