Abstract:
PROBLEM TO BE SOLVED: To provide a bar code scanner platform in which a gain of an analog signal which indicates a bar code is controlled by means of a control loop. SOLUTION: An MTF detector 310 generates: a value that indicates a low frequency portion (various wide elements, that is, various elements that have different optical focal points) of an analog signal; and a second value that indicates a high frequency portion (various narrow elements, that is, various elements that have the same optical focal points) of the analog signal. A processor 308 uses the first value, the second value and a reference amplitude to calculate a gain IE signal. The processor 308 supplies the gain signal to an AGC circuit 304, and the circuit uses matching JFET to supply a linear response to the gain signal. A noise filter 312 is validated or invalidated based on the first value, the second value and/or a bar code scanner platform reading rate. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To improve mechanical and optical characteristics by a micromechanical or microoptomechanical structure in a silicon (SOI) wafer on an insulator. SOLUTION: This invention provides the micromechanical or microoptomechanical structure. This structure is manufactured by processing comprising the following stages: that is, to define a pattern on a monocrystal silicon layer 12 separated from a substrate layer 14 by an insulating layer 16, to define the structure on the monocrystal silicon layer 12, to deposit and etch polysilicon layers 40 and 42 on the monocrystal silicon layer 12 while leaving polysilicon for forming a mechanical element or an optical element of the structure as it is, and to dissociate the formed structure.

Abstract:
PROBLEM TO BE SOLVED: To improve the mechanical and optical characteristic of a silicon (SOI) wafer on an insulating body by using a micro-mechanical or a micro- optomechanical structure. SOLUTION: The micro-mechanical or the micro-optomechanical structure is manufactured by a process including following stages. The structure is defined on a mono crystal silicon layer 12 separated from a substrate layer 14 by an insulating layer 16. Poly silicon layers 40 and 42 are formed on the mono crystal silicon layer 12 by vapor deposition and etching as the poly silicon forming a mechanical element or an optical element of the structure is left. A selected range of the mono crystal silicon layer 12 is exposed. The formed structure is dissociated.

Abstract:
A process including retrieving a list of one or more candidate objects with which an origin object can communicate using a standard command language, wherein at least one of the one or more candidate objects uses a command language different than the standard command language. The process queries the schema of one or more target objects selected from among the one or more candidate objects and uses the standard command language to transmit to the one or more target objects commands and/or data consistent with the schemas of the target objects.
