20090109410	Adjusting apparatus for projector - An adjusting apparatus is provided for a projector having a base. The adjusting apparatus includes a supporting member and a rotating member. The supporting member is partially received in the base of the projector and movably coupled to the base. The supporting member forms a plurality of teeth thereon. The rotating member is rotatably coupled to the base of the projector and partially exposed out of the base. The rotating member forms a plurality of teeth mating with the teeth of the supporting member, when the rotating member is rotated in either of two directions, the base of the projector correspondingly moves up and down relative to the supporting member.	04-30-2009

20100031206	METHOD AND TECHNIQUE FOR ANALOGUE CIRCUIT SYNTHESIS - Method and technique for analogue circuit synthesis. An analogue circuit usually includes many circuit components, and characteristics and functions of each circuit component are controlled by many corresponding parameters. In the presented invention, selected key design parameters of selected critical circuit components, as well as optimization targets, design specification or/and design constraint, are transformed into an optimization plan, and an optimization engine iterates circuit level or system level numerical simulations by changing values of the selected key design parameters recorded in the optimization plan, so as to find optimized parameters and circuit components which allow the analogue circuit to match the design specification/constraint and to approach the optimization target. Thus a systematic automation for analogue circuit synthesis/design/optimization is achieved.	02-04-2010
