摘要： A digital image capture and processing system comprising an illumination measurement subsystem for measuring the level of illumination at a particular region of the field of view (FOV) of the system during object illumination and imaging operations, and producing and storing an illumination measure for achieving a desired spatial intensity in a digital image to be formed and detected by the image formation and detection subsystem. An illumination control subsystem uses the illumination measure to control a LED-based illumination array during object illumination and imaging operations. A programmed image processor supports an image-processing based illumination metering program, as well as processes digital images formed and detected by the image formation and detection subsystem so as to read or acquire information graphically represented in the digital images. A computing platform supports the implementation of one or more of the subsystems above, and includes memory for storing at least one code symbol reading application.

摘要： A hand-supportable digital-imaging based system for reading bar code symbols involving: automatically detecting the presence of an object within a field of view FOV of the system, and in response thereto, automatically generating an image cropping zone (ICZ) framing pattern and projecting the ICZ framing pattern within the FOV and onto the detected object; visually aligning the code symbol on the detected object, within the ICZ framing pattern; manually actuating a trigger switch when the code symbol on the object is located within the ICZ framing pattern, and while the ICZ framing pattern and a field of illumination are being simultaneously projected onto the object during object illumination operations, forming and capturing a digital image of the code symbol on the detected object; automatically cropping the image pixels contained within the spatial boundaries of the ICZ framing pattern, from the pixels of the digital image; and decode processing the cropped image so as to read one or more 1D and/or 2D code symbols graphically represented therein.

摘要： Embodiments of a method for determining a mask pattern to be used on a photo-mask in a lithography process are described. This method may be performed by a computer system. During operation, this computer system receives at least a portion of a first mask pattern including first regions that violate pre-determined rules associated with the photo-mask. Next, the computer system determines a second mask pattern based on at least the portion of the first mask pattern, where the second mask pattern includes second regions that are estimated to comply with the pre-determined rules. Note that the second regions correspond to the first regions, and the second mask pattern is determined using a different technique than that used to determine the first mask pattern.

摘要： A method and mobile electronic device are provided that display, for a user, a packet switched congestion status of a wireless communication network that is useful for estimating a network quality of service. The method includes transmitting a packet switched congestion status inquiry message from the mobile electronic device to a first network element in the wireless communication network. A reply message received from the first network element in response to the packet switched congestion status inquiry message is then processed. The reply message includes transmission delay information obtained from a device transmission delay between the first network element and the mobile electronic device and a network transmission delay between the first network element and at least one packet switched support node. The packet switched congestion status is then determined based on the transmission delay information. Finally, the packet switched congestion status is displayed on the mobile electronic device.

摘要： A method and system for allocating subcarrier frequency resources for a relay enhanced cellular communication system is provided. The relay enhanced cellular communication system includes a base station, one or more mobile stations and one or more relay stations. Subcarrier allocation involves assigning a set of subcarriers by allocating subcarriers to one or more access communication links between mobile stations and their serving stations, to meet minimum data rate requirements of the access links, and allocating subcarriers to one or more relay communication links between the base station and relay stations to accommodate the data rates achieved on the corresponding access links. The serving stations may include one or more relay stations and the base station. Link balancing, multi-user diversity and minimum data rate constraint are jointly considered to achieve an optimal solution.
