摘要:
An automatic focusing camera which includes an image sensor is provided having a fixed lens system with a lens having an object side and an image side. The fixed lens system is located in a fixed position relative to the image sensor. A mirror is moveably positioned between the image side of at least one lens and the image sensor. The mirror is located at an angle such that an image observed through the fixed lens system is reflected toward the image sensor. An actuator is connected to the mirror and moves the mirror relative to the lens system to change a distance between the lens system and the image sensor to adjust an object focal length between an object and the object side of the lens.

摘要:
A system for scanning objects having at least two linear array sensors, adapted to detect light input signals, is provided. A lens is optically connected to each of the linear array sensors, and are adapted to receive and transmit an optical image located in a respective lens field of view along a respective lens axis to the respective one of the at least two linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis across a depth of the field of view is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe. This arrangement provides a wider system field of view with generally more uniform resolution.
摘要:
A system and method for removing perspective distortion from an image of an object (112) moving along a transport device (114) having a top surface (124) is disclosed. A line scanner (110) to create a first image of an object. The first image is composed of a plurality of scan lines, each having a resolution. Each of the scan lines is then rescaled, so that the resolution of each scan line is equal to the resolution of every other scan line. Each of the scan lines is processed in two halves so that the center lines of the scan lines are co-linear after rescaling. The line scanner is optionally configured to vary its field of view as a function of the distance between the line scanner and the portion of the object being scanned.

摘要:
An RF identification label includes a selectively activatable battery and control and RF generating circuitry which is coupled to the battery. The battery includes two separate components which are brought together in operative contact to activate the battery and provide power to the control and RF generating circuitry. The preferred embodiment of the control and RF generating circuitry includes a programmable integrated circuit with contacts which permit programming by a user to define the identification signal which is generated.
