Abstract: Disclosed are support-activators and catalyst compositions comprising the support-activators for polymerizing olefins in which the support-activator includes clay heteroadduct, prepare from a colloidal phyllosilicate such as a colloidal smectite clay, which is chemically-modified with a heterocoagulation agent. By limiting the amount of heterocoagulation reagent relative to the colloidal smectite clay as described herein, the smectite heteroadduct support-activator is a porous and amorphous solid which can be readily isolated from the resulting slurry by a conventional filtration process, and which can activate metallocenes and related catalysts toward olefin polymerization. Related compositions and processes are disclosed.

Abstract: A chip design-in aid system, wherein the chip has a plurality of chip controlling registers for storing at least one parameter. The system includes a user interfance for inputting user setting data, the user setting data corresponding to at least one function of the chip; a data processing unit for processing the user setting data; and a parameter adjusting unit for receiving the processed user setting data from the data processing unit, and transmitting the processed user setting data to the chip, so as to adjust the parameter stored in the chip controlling registers, whereby the chip is set to perform the function corresponding to the user setting data.

Abstract: A projector. The projector comprises a projection light source, a first digital micro-mirror device, and a second digital micro-mirror device. The projection light source emits a projection beam toward the first digital micro-mirror device. The first digital micro-mirror device reflects the projection beam to the second digital micro-mirror device. A first micro-mirror on the first digital micro-mirror device is rotated in a horizontal direction to adjust the horizontal position of the projection beam. The second digital micro-mirror device reflects the projection beam from the first digital micro-mirror device to a projection plate. Second micro-mirrors on the second digital micro-mirror device are rotated in a vertical direction to adjust the vertical position of the projection beam.

Abstract: A program correction method. A program-driven electronic device for implementing the program correction method contains an erasable memory storing a program comprising to-be-replaced codes need to be replaced stored in a first section. First, updated codes for replacing the to-be-replaced codes are acquired. Next, the updated codes are stored in a second section of the erasable memory. An initial instruction of the to-be-replaced codes is amended to be an exception-causing code which generates a corresponding code-replacement exception when executed. The updated codes are executed when the corresponding code-replacement exception is received.

Abstract: A new method which employs a mixed-valence cluster of M.sub.y.sup.z+ [Fe(II)(CN).sub.6 ] coated on an electrode surface to determine hydrogen peroxide concentration electrochemically is developed. M of the mixed-valence compound can be Co, Ni, Cr, Sc, V, Cu, Mn, Ag, Eu, Cd, Zn, Ru or Rh; z is the valence state of M; and y=4/z. In addition, this invention also reveals a new approach to determine a concentration of a hydrogen peroxide precursor, wherein a catalyst is immobilized in the matrix or on the surface of the mixed-valence compound on the electrode. In a typical biochemical system, the catalyst can be a glucose oxidase and blood sugar is catalyzed to form hydrogen peroxide.
