    摘要: Systems and methods for managing window transparency for a computer display, making windows wholly transparent or semi-transparent, on a window-by-window basis. Window transparency is triggered by monitoring messages exchanged between a program and an operating system, or by a user action. Upon detection of a first message indicating that a window of the display should be transparent, a layered display mode for the window is initiated. Upon detection of a second message indicating that the window should no longer be transparent, the layered display mode for the window is terminated. The layered mode can be controlled by the operating system or by a graphics processor.

    摘要: A closed loop, high-speed tape transporter (10) includes a vacuum supply (11A), a first vacuum column (40) operatively connected to the vacuum supply (11A) and positioned upstream from a pick-up head (100) and downstream from a tape bin (64) for receiving the loop of tape and exerting a vacuum-induced holdback tension thereon, a second vacuum column (50) operatively connected to the vacuum supply (11A) and positioned downstream of head (100) and upstream of the tape bin (64) for exerting a vacuum-induced pull forward tension on the tape in opposition to the holdback tension exerted on the tape by the first vacuum column (40). A motor-driven capstan (60) is positioned intermediate the pick-up head (100) and the second vacuum column (50). Capstan (100) is driven at a constant speed equal to the ideal reference tape duplication speed. Tape drive capstans (62A) and (70A) cooperate with the first and second vacuum columns (40) and (50) for moving the tape. A servo-control (42 ), (45), (48) senses changes in the position of the tape within the first vacuum column (40) and sends a signal to tape drive (70A) and a servo-control (58), (55), (56) senses changes in the position of the tape within the second vacuum column (50) and sends a signal to tape drive (62A). The speed of the tape is varied as it moves through the first and second vacuum columns (40), (50) thereby minimizing tension induced speed variation in the tape in the region of the pickup head (100).

    摘要: As tape moves through a closed loop, high-speed tape transporter (10) loops of the tape are accumulated and stored in a tape bin (64). The capacity of the tape bin (64) is increased by extracting air from and lowering the air pressure in the region of the bin (64) occupied by the loops of accumulated tape and inside the loops of tape sufficient to cause the accumulated tape to compress into tighter loops which occupy less space in the tape bin (64). Air extraction takes place through a vacuum port (95) which communicates with the interior of the tape bin (64) and which is connected to a vacuum supply (11A).

    摘要: An audio tape cassette winder (10) is disclosed which includes a splicer (30) which winds splicing tape ("T") onto a cassette ("C"). Tape ("T") is applied by means of a square applicator wheel 85 which simultaneously translates and rotates into and out of tape applying contact with two tape ends ("L" and "A") to be spliced. Application of tape ("T") to tapes to be spliced ("L" and "A") is assisted by positive air pressure through ports (106a-d) on respective tape carrying surfaces (85a-d) as each tape carrying surface successively applies tape ("T") to the tapes to be spliced ("A" and "L"). The positive air pressure is applied only for a very short period of time concurrent with physical impact of successive tape carrying surfaces (85a-d) with the tapes to be spliced ("A" and "L"). The invention proceeds substantially as described above with reference to the apparatus.

    摘要: A vacuum column (34) is used in a closed loop, high-speed tape transporter (10) to maintain constant tension on a moving loop of tape as it is delivered to a pick-up head (20) of the transporter (10). A motor driven capstan (35) intermediate a tape storage bin (23) and the vacuum column (34) pulls the loop of tape from bin (23) and delivers it to the vacuum column (34). A servo-control (39), (40), (41) senses changes in the position of the tape within the vacuum column (34) caused by tension changes of the tape within the bin (23) and sends a signal responsive to the change of position of the tape in the vacuum column (34) to the capstan motor (31), thereby changing its speed sufficient to maintain the position of the tape within capstan (34) at a relatively constant level. Sensing can be by means of a vacuum slot (34), an ultrasonic proximity indicator (42) or a series of photo-optical sensors (44), (45).

    摘要: An integrally formed ratchet (90) and star wheel (95) is disclosed which rotates in unison with a tape applicator wheel (85). Eccentrically formed fingers (96a-d) cooperate with a downwardly facing wall to align and position applicator wheel (85) into correct position after each reciprocation of the splicer (30). Correct alignment is essential because a cutter blade 127 cuts the tape on the applicator wheel into pre-determined lengths by passing through a notch (104) in applicator wheel (85). Misalignment of the applicator wheel (85) may cause blade (127) to impact the applicator wheel (85) itself, damaging or destroying it.

    摘要: A method for displaying a desktop display surface. The method includes creating a render target surface having substantially the same dimensions as a desktop display surface, casting the desktop display surface as a texture, and setting the render target surface as a scanout read location. The method further includes creating a two dimensional rectangular object, rendering the two dimensional rectangular object by mapping the desktop display surface texture to the two dimensional rectangular object, storing the rendered two dimensional rectangular object to the render target surface and scanning out the rendered two dimensional rectangular object from the render target surface.

    摘要: A home hearing test for use with a conventional home audio system comprising an audio player and a set of headphones connected to the audio player. The home hearing test includes an audio medium such as a compact disc playable in the audio player and containing a calibration tone recorded at a predetermined decibel level and a number of prerecorded sequences of tones. Each sequence has tones recorded at different decibel levels and decreasing by a step value. In a first sequence for obtaining a rough estimation of hearing threshold level, the tones start at 70 dB HL and decrease by 10 dB steps to 0 dB HL. In secondary sequences, tones start and end with tones from the first sequence and decrease in 2 dB steps. The home hearing system includes a calibration device for calibrating the output of the audio system to the ears of a person wearing the headphones against the predetermined decibel level of the calibration tone.

    摘要: A desktop manager application (20) manages graphical object creation, repositioning, resizing and related object placement functions in the context of a multi-monitor or other enhanced desktop environment. In a preferred implementation, the program manager (20) manages multi-pass window creation by allowing a graphical user interface operating system (16) to fill in a window structure in a hidden form and thereafter analyzing the window's coordinates relative to selected display criteria such as avoiding monitor splits. Based on this analysis, the program manager (20) selectively repositions the window under consideration in accordance with the display criteria. The program manager (20) thus provides a more user friendly interface between a GUI operating system (16) and applications in the enhanced desktop environment.
