Abstract:
A testing apparatus for flip chip LEDs includes a transparent substrate, a spacing member, a flexible transparent carrier, and a vacuum generator. The spacing member is configured on a first surface of the transparent substrate. The flexible transparent carrier is removably assembled to the spacing member so that a closed space is formed by the flexible transparent carrier, the spacing member, and the first surface of the transparent substrate. The vacuum generator is connected to the closed space for pumping air out of the closed space, and then a part of the transparent substrate clings to the first surface to form a testing area for loading the flip chip LED.
Abstract:
A flip-flop structure with reduced set-up time is provided. The flip-flop includes the first master latch receiving a function data through the first switch controlled by a clock signal, the second master latch receiving a scan data through the second switch controlled by the clock signal, and a slave latch connected to the first master latch through the third switch controlled by the clock signal. The second master latch is coupled to the first master latch through the fourth switch controlled by the scan enable signal so that the scan enable signal controls whether the function data or the scan data becomes an output from the first master latch to the slave latch, and the slave latch is used to latch and transmit the output from the first master latch.
Abstract:
A conveyor system comprising: a track section comprising a control system; a drive system that is controlled by the control system; a plurality of moving elements that are driven by the drive system; a pallet support apparatus; a plurality of pallets that are configured to engage with the moving elements and move on the pallet support apparatus; and a plurality of workstations provided along the track section, each workstation at a predetermined pitch from each other workstation, wherein at least some of the pitches are different among workstations, wherein the control system, drive system and moving elements are configured such that each pallet of the plurality of pallets is independently advanced through the workstations based on the pitches of the workstations.
Abstract:
A method compensates for changes in drop mass of drops ejected by ink jets in a printhead of an ink jet imaging device. The method comprises identifying an average drop placement position for a printhead with reference to ink drop positions on an image receiving member and adjusting a parameter of one or more ink jet driving signals in response to the average drop placement position being greater than a predetermined threshold.

Abstract:
A method for testing light-emitting devices in a batch-wise, associated with a system for the same purpose, comprises the steps of: preparing the light-emitting devices on a moving carrier unit in a manner of aligning a predetermined longitudinal direction of the light-emitting devices with a predetermined transportation direction of the moving carrier unit, each of the light-emitting devices further having plural light-emitting elements; transporting orderly the light-emitting devices to pass a test area on a base of the system, in which the base energizes only the light-emitting elements within the test area; and, a solar cell module detecting continuously the energized light-emitting elements within the test area and further forming signals with respect to photo energy received in the test area.
Abstract:
Improved methods and systems that assist a user in searching media items on a portable electronic device are disclosed. According to one aspect of the invention, a portable electronic device is provided with a search function that enables a user to search for media items resident on the portable electronic device. The search function can search through different types of media items. Those of the media items that are deemed matching can be ranked in order of relevance and displayed in a list for the user. Thereafter, the user can navigate the list to select one of the listed media items for playback. According to another aspect of the invention, various graphical user interfaces can be presented on a portable electronic device to assist a user in interacting with the portable electronic device to utilize a search function.
Abstract:
An electro-optic, noncontact, interior cross-sectional profiler (a "probe") and method of using the probe to determine the physical characteristics, such as interior dimensions, of an interior surface of a tubular structure, such as pipe, tubing, gun barrels and the like. The probe utilizes a disc of unfocused light to illuminate a cross-section of the interior surface and images the illuminated cross-section from the interior surface to a photodetector array, where the image can be evaluated. The probe is useful for off-line and on-line (or "in-line") processes, such as an extrusion process.
