Abstract: Described are improved systems, computer program products, and methods for obtaining space usage information within a clustered database system. Some approaches provide an improved algorithm and structure that gives the ability to compute the latest and accurate space usage with only in-memory operations.

Abstract: There is disclosed an inspection system that combines 2-D inspection and 3-D inspection of the components of an electronic device into one compact module. The inspection system of the present invention comprises a 2-D image acquisition assembly for inspecting 2-D criteria of the components, a 3-D image acquisition assembly for inspecting 3-D criteria of the components, and a computer for control and data analyzing. The 3-D image acquisition assembly comprises a 3-D image sensor and a 3-D light source. The 3-D light source is preferably a laser capable of generating a planar sheet of light that is substantially perpendicular to the inspection plane of the electronic device. The 2-D image acquisition assembly comprises a 2-D sensor and a 2-D light source positioned above the holder. The 2D and 3D image acquisition assemblies are arranged so that the 2D inspection and 3D inspection can be done while the electronic device is being held in one location.

Abstract: A flash disk with wireless Blue tooth function comprises a battery capable of storing power for supplying power to other element of the body; a USB port connected with anther USB port of a external device; a control unit for controlling data transmission of the USB port; a blue tooth module being a wireless transmission element; a memory control unit; and a flash memory unit for storing data. The flash disk with wireless blue tooth function having a Flash RAM is a small size one. The device has not only a USB port for data transmission, but also has a blue tooth module so as to have the function of wireless data transmission. Thus, the flash disk is able to transmit data by using a blue tooth module to wirelessly transmitting data from one computer to another computer.

Abstract: A notebook computer with an independent number and operation inputting device comprises a mainframe body having a keyboard and a touch panel; two sides of the touch panel being installed with plate portions; a receiving groove of one of the plate portions; an independent number input device being installed in the receiving groove; a touch panel being installed at a top of the number input device; a shaft serving to connect the movable cover to the plate portion. The independent number and operation inputting device includes at least number keys, the operation keys, and keys of “Num Lock”, “Del”, “Enter”, etc. By the independent number input device, it is only necessary to input characters and numbers to the notebook computer alternatively so as to achieve the objective of easy operation and increase typing efficiency.

Abstract: A method and apparatus is disclosed for non-contact, on-line inspection of objects including a ball grid array package by means of a shadow moiré technique combined with a novel flash phase-shifting method. The grid pitch size, ball height, ball diameter, missing ball, coplananity can be determined or measured within several seconds. The apparatus includes a camera for viewing the object, a plurality of light sources arranged in a line for illuminating the object to be inspected, a frame grabber for capturing images of the object, an I/O adapter card for controlling the light sources and a personal computer for data processing. The individual components are integrated into system which provides a three dimensional map which is obtained quantitatively using a novel algorithm. The system can provide coplananity data, as well as data relating to grid pitch, ball height, ball diameter, and missing ball information.
