Abstract:
A metal to glass seal comprising a metal cap having a depth D and comprising a base and a crown, a glass tube inserted into the metal cap to a depth less than D, and a low melting point glass (LMPG) material between the glass tube and the crown, such that when the LMPG material is heated to or above a melting temperature and then cooled, the LMPG material seals the metal cap to the glass. Methods of sealing metal to glass comprise, inserting a glass tube into a metal cap, the metal cap having a depth D and comprising a base and a crown, filling a space between the glass tube and the metal cap with a LMPG material, heating the LMPG material to or above a melting temperature, and cooling the LMPG material at least until it solidifies and seals the metal cap to the glass tube.
Abstract:
A method(600) and an apparatus for determining a point for processing a workpiece(108). The method(600) of determining a point for processing a workpiece(108) comprises: receiving an input representing an offset for adjusting a sample workpiece point, the sample workpiece point corresponding to a workpiece point for processing the workpiece(602); adjusting the sample workpiece point based on the input, so as to generate an adjusted sample workpiece point(604); and determining the workpiece point based on the adjusted sample workpiece point(606).
Abstract:
Embodiments of the present disclosure provide methods, apparatuses, systems (100) and computer readable media for managing a camera system (160). The camera system (160) comprises at least a first camera (110) and a second camera (120). In the method, a first position and a second position for a first object (310) and a second object (320) are obtained from the first and second cameras (110,120), respectively. The first and second objects (310,320) are used for calibrating the camera system (160). After a movement of the first and second objects (310,320), a third position and a fourth position for the first and second objects (310,320) are obtained from the first and second cameras (110,120), respectively. Here, a relative object position between the first and second objects (310,320) remains unchanged during the movement. A relative camera position between the first and second cameras (110,120) is determined based on the first, second, third, and fourth positions. With these embodiments, the camera system (160) may be managed with the separated first and second objects (310,320) in an accurate and effective way.
Abstract:
A method (100) of picking an object from a container (230) by a robot manipulator (211) is disclosed, and it includes obtaining a first image containing pixels representing greyscale information for the object (220) and the container (230); obtaining a second image containing pixels representing 3D spatial information for the object (220) and the container (230); identifying at least one surface of the object (220) in the first image based on the greyscale information; identifying pixels for the at least one surface of the object (220) in the second image based on the identified at least one surface of the object (220) in the first image and the 3D spatial information; and controlling, based on the identified pixels in the second image, the robot manipulator (211) to approach the identified at least one surface for picking the object (220). The device, system or method according to the present disclosure provides an improved solution for making the computing resources required by the image analysis less demanding. In addition, the processing speed will be greatly improved, and thus the picking motion of the robot manipulator (211) is fast and accurate.
Abstract:
It is therefore an objective of the invention to provide a mobile platform, a transfer system, and methods for operating the same. The mobile platform includes a carriage configured to be supported by its wheels on a ground surface; a robot mounted on the carriage; a plurality of first support members deployable and retractable for raising and lowering the carriage so that the wheels of the carriage are relieved from and placed on the ground surface; and at least one cantilever having a second support member arranged at one of its ends, being configured to rotatably engaged with the carriage by the other of its ends, where the second support member is deployable and retractable for engaging and disengaging the ground surface for balancing the carriage. By having the configuration of the mobile platform and the methods for operating the mobile platform, it makes it possible for the mobile platform to occupy a relatively small space when moving to a predetermined location, while with the help of the unfolded cantilevers, the mobile platform can remain stable without foot screws during work process.
