Abstract: DC offset introduced into a differential signal is compensated for by DC offset correction circuitry. The DC offset correction circuitry receives a known training pattern of alternating logic high and logic low levels (i.e., 10101010 etc.). In one embodiment, the received signal is integrated and the result compared to a predetermined reference level. The result of the comparison is used to adjust a DC offset correction value that is added to the received signal. This process is iteratively performed until successive results of the comparison indicate that the DC offset has been compensated for in another embodiment, the duty-cycle of the received signal is calculated. The result of the duty-cycle calculation is used to iteratively adjust the DC offset correction value.

Abstract: An animated children's toy including a gear system for providing intermittent and reciprocal motion. The gear system includes a drive gear and a driven gear. The gear system is adapted to have a non-rotating configuration and an engaged configuration. In the non-rotating configuration the driven gear is prevented from rotating, and a corresponding portion of the animated children's toy is not moving. In the engaged configuration the driven gear rotates and a corresponding portion of the animated children's toy moves.

Abstract: Sputtering of the cathodes of a cold cathode fluorescent lamp is reduced or eliminated by removing electrodes altogether from the sealed envelope containing the gaseous medium. Electric field is then applied by means of electrically conductive members outside the tube. Alternatively, the current passing between electrodes can be spread over multiple sub-electrodes so that the current flow and sputtering experienced by each individual sub-electrode will be reduced. Different designs are employed to facilitate heat dissipation for high power and high intensity cold cathode fluorescent lamp applications. Thus, a container for the fluorescent lamp tube may be omitted altogether and adjacent rounds of a spiral-shaped lamp may be attached together by an adhesive material. Alternatively, the container may be open at one end to facilitate heat dissipation. Or the container for the lamp and the housing from the driver may each contain a hole to allow air circulation to carry away heat.

Abstract: A packaging system for storing and dispensing liquid or powder products. The product is housed within an inner container having a body defined by a side wall and an opening therein for dispensing the product. A flexible outer shell substantially surrounds the inner container and is removably secured thereto. The outer shell can be designed to resemble the three-dimensional shape of an animal, cartoon character or the like, for superior aesthetic appeal. The contents of the inner container may be sealed with a closure. A three dimensional topper may be provided, which is designed to resemble the head or upper portion of the character being depicted. The outer shell can be squeezed to cause dispensing of the product from the inner container, and can be adapted to hold inner containers of all shapes and sizes. The inner container is easily replaced once empty.
