Abstract: Disclosed is an apparatus for the batch polishing of workpieces, the apparatus includes an annular cavity, in which several workpieces are mounted, magnetic abrasives, which are arranged in the annular cavity and used for polishing the workpieces, and multiple magnet sets, which are used for generating a magnetic field for the magnetic abrasives in order to remove a surface material of the workpieces, wherein each of the magnet sets comprises magnets arranged on both inner and outer sides of the annular cavity and configured to rotate about the axis of the annular cavity.

Abstract: The present invention relates to LED lamps suitable for forming automotive lighting systems, made of high power lambertian LEDs and a TIR collimator lens. In the present invention, a novel TIR collimator lens is developed to collect the light emitted from the LED source and through a pillow lens array; redistribution occurs to form a light pattern meeting ECE requirements.

Abstract: A pivotally-leveraged manual centrifugal drive according to a preferred embodiment of the invention for use with a bowl and a basket formed to nest within the bowl, comprising: a) a housing formed to mate with the bowl; b) a rotation wheel rotatably connected to the housing, formed to mate with the basket, and having a plane of rotation; c) a handle pivotally attached to the housing and oriented to move in a plane that is substantially perpendicular to the plane of rotation of the rotation wheel; and d) gears connecting the handle to the rotation wheel. Also disclosed are an automatic clutch that engages the rotation wheel only when the handle is moved in one direction, and a braking mechanism that includes a disk having a diameter substantially smaller than the rotation wheel.

Abstract: A method for optimizing the deployment of RFID apparatus, and a RFID deployment optimizer of use thereof are provided. The method includes the steps: A. analyzing the interrogation zone where the RFID apparatus are deployed, B. identifying the readability o RFID tag associated with different sets of placement on a target object inside the interrogation zone, and C. selecting the best deployment alternative based on the analysis result of the interrogation zone attained in the step A and all the readabilities of RFID tag associated with different sets of placement identified in the step B.

Abstract: The present invention relates to a method of automated process control operation wherein a physical object is directed into a read zone, information stored on an ID Container attached to the physical object is retrieved, physimetric property of the physical object is captured, the retrieved information is processed to provide recorded physimetric property specific to the physical object, the recorded physimetric property and captured physimetric property are passed to an analysis algorithm for comparison, and the results of the comparison are delivered to a controlling device. The results of the comparison will determine whether the physical property will continue to pass through the read zone or require to be rotated by the operator.

Abstract: Ultra-precision freeform surfaces are important to the development of complex and micro-optical-electro-mechanical devices used in many photonics and telecommunication products such as F-theta lenses for laser printers. These surfaces are complex and large scale surface topologies with shapes that generally possesses no rotational symmetry. Due to the geometrical complexities of these ultra-precision freeform surfaces, it is difficult to characterize the form accuracy and surface quality of freeform optical surfaces.

Abstract: The present invention relates a scanable product made of a physical object and an ID Container, such ID Container possessing on its memory a Unique ID and a stored coded locking mechanism. The stored coded locking mechanism is generated by inputting physimetric property of the physical object and its Unique ID into hash functions to create an unintelligible code. Methods of making such a scanable product, and methods of authenticating a scanable product are also taught.
