The invention provides a multi-use light fixture that includes a light engine, a rugged housing, and an external power supply removeably embedded within an optional external enclosure. The light fixture includes several novel heat management features designed to reduce the risk of failure and thereby increase the reliability of the light fixture. The light engine includes groups of light modules, each having a light emitting diode (LED) and a zener diode. The housing includes an internal gap defined between the a circuit board and the housing. The housing also includes an arrangement of external fins and vents that dissipate heat generated by the light engine. The lens cover includes a plurality of inlets to supply ambient air into the fixture. During operation, heat is generated by the light modules, namely the LEDs, and then is transferred along a first flow path through a main body portion of the housing and the fins for dissipation to ambient and a second air flow path whereby ambient air flows through the light engine to increase the performance and efficiency of the light engine.

An adaptive “temporal audio scaler” is provided for automatically stretching and compressing frames of audio signals received across a packet-based network. Prior to stretching or compressing segments of a current frame, the temporal audio scaler first computes a pitch period for each frame for sizing signal templates used for matching operations in stretching and compressing segments. Further, the temporal audio scaler also determines the type or types of segments comprising each frame. These segment types include “voiced” segments, “unvoiced” segments, and “mixed” segments which include both voiced and unvoiced portions. The stretching or compression methods applied to segments of each frame are then dependent upon the type of segments comprising each frame. Further, the amount of stretching and compression applied to particular segments is automatically variable for minimizing signal artifacts while still ensuring that an overall target stretching or compression ratio is maintained for each frame.

It is intended to provide an image forming apparatus and image forming method capable of obtaining a comparatively high-quality image output even under a correction mode that gives preference to processing time required for correction, and capable of suppressing interruption of image formation to the utmost under operational condition such that internal temperature changes continuously. There are saved last five detections of positional shift quantity under first correction mode that gives preference to correction accuracy for each temperature band. Under second correction mode that gives preference to processing time required for correction, there is calculated a difference of a value actually obtained through measurement and an average value of data history belonging to a target temperature band (#7 through #9). Furthermore, the difference is multiplied by a reliability coefficient of main scanning direction and that of sub scanning direction, respectively, to determine correction quantity (#10, #11). Thereby, excessive change of correction quantity is prevented.

c, m, and y, which are the primary colors, are calculated from inputted RGB data. Duty limitation is then applied to c, m, and y by means of the limit amount α. c′, m′, and y′, which have been limited by α, are then normalized. The largest limit amount is β when the normalized values are less than 200%. If these values are between 200% and 250%, β+((c″+m″+y″) / 255−2)×2γ is then the largest limit amount, which is β+γ when the values are equal to or more than 250%. C, M, Y, and K are obtained by subjecting c′, m′, and y′ to under color removal and black generation processing. Unless the total of these values exceeds the largest limit amount, C, M, Y, K are outputted as is as the output values C′, M′, Y′, and K′. When the largest limit amount is exceeded, Duty limitation is applied.

A segmentation process section classifies signals of pixels in input image data into respective signals of a black text / low density area, a black text / high density area, a color text area, and an area other than a text area. A black generation and under color removal section performs an under color removal process with respect to the signal of the black text / low density area so that an amount of UCR is a middle value (C, M, Y) of signals indicative of color component density levels. Consequently, it is possible to prevent color fringing and a white spot at a time when chromatic aberration occurs in the input image data.

A processing apparatus processes input pixel data by referring to pixel data of peripheral pixels. The processing apparatus divides an input image in a first direction, inputs pixel data of a divided image divided in the first direction in a second direction crossing the first direction at a right angle, and stores the inputted pixel data. When a pixel to be referred to for processing the stored pixel data is not included in the divided image, the processing apparatus outputs pixel data of the reference pixel based on the stored pixel data, and processes the stored pixel data by referring to the pixel data of the reference pixel.
