Effective differential dynamic range in a differential pixel detector is increased by avoiding saturation effects due to common mode contribution in optical energy to be detected. Photocurrent generated by each photodetector pair is directly integrated by an associated capacitor over an integration time T. Within time T, before either integrated capacitor voltage reaches Vsat for the photodetector, at least one of the capacitors is reset to a voltage such that the desired differential detector signal is still determinable. Reset may be generated externally or internally to the differential pixel detector.

In a maskless particle multibeam processing apparatus, a particle beam is projected through a pattern definition system producing a regular array of beamlets according to a desired pattern, which is projected onto a target which moves at continuous speed along a scanning direction with respect to the pattern definition system. During a sequence of uniformly timed exposure steps the beam image is moved along with the target along the scanning direction, and between exposure steps the location of the beam image is changed with respect to the target. During each exposure step the target covers a distance greater than the mutual distance of neighboring image elements on the target. The location of the beam image at consecutive exposure steps corresponds to a sequence of interlacing placement grids, and after each exposure step the beam image is shifted to a position associated with a different placement grid, with a change of location generally including a component across the scanning direction, thus cycling through the set of placement grids.

A radio base station includes multiple antennas associated with a cell. Multiple mobile radios are selected to receive transmissions over a shared radio channel during a predetermined time interval. Information is transmitted over the shared radio channel to multiple mobile radios in the cell during the predetermined time interval using multiple antenna beams. As a result, interference from the transmission appears as white additive Gaussian noise in time and in space in the cell. A “flashlight effect” caused by a single beam transmission over the shared channel during a predetermined time interval that would normally detrimentally impact mobile channel quality detection is avoided. Other methods for avoiding the flashlight effect are described.

A flip-chip semiconductor package structure and a package substrate applicable thereto are disclosed. The package substrate includes a body having at least a chip-attach area disposed thereon; a plurality of solder pads disposed in the chip-attach area and arranged at different intervals; and a fluid-disturbing portion disposed in the chip-attach area at a position where the solder pads are loosely arranged. A flip-chip semiconductor chip is mounted on the solder pads via conductive bumps and an underfill material is filled between the package substrate and the flip-chip semiconductor chip, the underfill material encapsulating the conductive bumps and the fluid-disturbing portion. By protrudingly disposing the fluid-disturbing portion at a position where the conductive bumps are loosely arranged, that is, the conductive bumps having bigger intervals therebetween, gap between the package substrate and the flip-chip semiconductor chip can be reduced so as to increase capillary attraction generated by capillary phenomenon, thereby balancing flow rate of the underfill material between the conductive bumps that are arranged at different intervals and thus avoiding problems of void formation, subsequent popcorn effect or delamination as encountered in the prior art.

An automated microscope and computer system captures a set of images for a capture area in a plurality of focal planes. The images can then be integrated into composite images for browsing to simulate viewing an item, such as a biological sample, under a microscope. A corrective filter can be constructed from the images to avoid an effect called “tiling.” Before capture, variable focal plane error can be avoided by collecting z locations for a set of points in the capture area. During image browsing, entire composite images can be loaded into memory in compressed form. Compressed image portions can be pre-decompressed to avoid delay as a browsing user navigates throughout the composite images. Pre-decompression can be done by a thread separate from the thread performing navigation operations.
