Abstract: A container includes a container portion and a lid portion. The container portion presents a tab rim and internal threads. The lid portion presents a plurality of flexible removable tabs disposed around its outer periphery. The tabs are adapted to engage with and interlock with the container tab rim when the lid portion is pressed down on the container. The lid portion also has helical threads that are arranged to engage the helical threads of the container portion. At least one of the set of helical threads of the container portion or the set of helical threads of the lid portion are able to flex when the lid portion is pressed down upon the container portion. A closed container may be adapted for repeated use by removing the tabs and using the threaded lid portion to open and close the container.

Abstract: Pinene copolymers which function as crystallizable tackifiers are described. Also described are temperature switchable pressure sensitive adhesives comprising an elastomer and a crystallizable pinene-based tackifier. These pressure sensitive adhesives exhibit a sharp reduction in peel strength when the temperature is raised above the switching temperature. The adhesive properties of these adhesives may be readily tuned by adjusting the ratio of the elastomer and the crystallizable tackifier, and by altering the crystallizable group on the tackifier. The temperature switchable pressure sensitive adhesives have use in medical, consumer, and industrial applications.

Abstract: A method for driving a multiplexed LCD panel (38). An LCD controller (20) controls the LCD panel (38) and provides a low power mode which refreshes a subset of the display panel (40) sequentially while refreshing the rest of the panel (38) in parallel. By resolving the panel into these portions, the present invention reduces the power consumption of an LCD module. Display information is stored in a memory (12) and provided to the controller (38) which drives the LCD panel (38). A reset signal eliminates fetching and clocking of zeroes for common areas in the display. One embodiment bit fills to provide a two tone display in low power mode.

Abstract: A Schmitt trigger (30) operates at low power and low frequency and can be implemented in a small amount of surface area on an integrated circuit. Specifically, the Schmitt trigger (30) includes transistors (34, 40) that are implemented as long channel devices and operate in a linear region for providing resistive elements, and another pair of transistors (44, 46) that function as non-linear devices allowing a current through the Schmitt trigger (30) to provide both a reference and the switchpoints for the Schmitt trigger (30). These transistors also establish low current through the Schmitt trigger (30).
