Patent EP-0423053-A2 (EP)
Inventor: BARTOLANZO LEO JOSEPH JR
IPC: H04L12/56
Filed: 1990-08-22
Abstract: A process for selecting a least weight path between two nodes (10, 16) in a data communication network uses par­tial trees created and cached in prior route selection operations. All root nodes (12, 14) on possible paths between the two nodes (10, 16) are identified. Any cached tree having a root matching one of the identified root nodes (12, 14) is retrieved from storage. If necessary, each retrieved tree is extended until it includes all possible destination nodes. The extended and/or retrieved trees are used to select the least weight path between the two nodes (10, 16). The extended tree is then cached for possible use in future route selection operations.

Abstract: A process camera (1) includes: an original holder (12); a lens for projecting an image of the original on an image forming plane; a frame (2) having an opening (20) defining the image forming plane; a focusing glass (4) attached to the frame (2) movable between a portion covering only a part of the opening of the frame (2) and an open position freeing the opening for forming an image of the original of the surface thereof; a vacuum board (5) for holding a film thereon; and a member for mounting to the frame the vacuum board (5) rotatably around a predetermined axis of rotation between a closed position covering all of the opening (20) and a position covering only a part of the opening (20). Since the area of the focusing glass (4) is selected to be smaller than the area of the opening (20), the area required by the focusing glass (4) at the open position is small. The axis of rotation of the vacuum board (5) is provided crossing the opening (20), but not along sides of the opening (20). The axis of rotation of the vacuum board (5) is provided at a position other than an end portion of the vacuum board (5).

Abstract: Progressive surface for a progressive spectacle lens, which in conjunction with a short progression zone between the distant area and the reading area has a large usable width of this zone and of the near-vision zone, and in which the maximum value which the surface astigmatism reaches on the progressive surface is less than 1.1 times the surface addition. Such a progressive surface is achieved when it is formed to be continuously differentiable twice and fulfils a combination of six features which relate to the distribution of area astigmatism and mean surface refractive power over the progressive surface.

Abstract: In a high-speed signal multiplexing circuit, when data supplied to an input terminal (D₀-D₃) of a flip-flop circuit (13₀-13₃) differs from the data which has been latched in the flip-flop circuit (13₀-13₃), an exclusive OR circuit (14₀-14₃) supplies a control signal to a clock signal input terminal (CK₀-CK₃) of the flip-flop circuit (13₀-13₃). The flip-flop circuit (13₀-13₃) latches the data supplies to the input terminal (D₀-D₃) in response to the control signal. A data reading section (12) generates a read signal in synchronism with a clock signal. The data latched in the flip-flop circuit (13₀-13₃) is successively read out in response to the read signal.

Abstract: A first-in-first-out buffer is described for transferring data between two asynchronous clock regimes. The buffer comprises a first register file, for transferring data from the slow to the fast clock regime, and a second register file for transferring data in the opposite direction. The write addresses for the first register file are produced by a counter in the slow clock regime, and converted back to standard binary, and a predetermined offset is added to the result, so as to produce a read address for the first register file. This is also used as the write address for the second register file. The read address for the second register file is produced by adding a predetermined offset to the output of the counter. Thus, the read and write addresses of the two register files are always in a fixed relationship, so that it is not necessary to provide special logic for detecting the buffer full and buffer empty conditions.

Abstract: The object of the invention is to describe a method for frequency-to-voltage conversion which avoids the imbalance in the characteristic which occurs in state-of-the-art converters. The object is solved by shifting the frequency signal which is applied to an input (19) of the frequency-to-voltage converter (26) with a reference frequency (fr) into a higher frequency signal. The phase of this frequency signal is compared with the phase of a signal which is obtained via a balanced voltage-to-frequency converter (26) from the signal at the output (28) of the frequency-to-voltage converter and is also shifted into a higher frequency signal. The phase of the comparison signal is then compared with the phase of the reference frequency. The figure shows a block diagram of a frequency-to-voltage converter. <IMAGE>

Abstract: The effective resolution of a colour display device such as a liquid crystal display device is enhanced by offsetting one of the colour components. A three component colour signal 50 being used to generate a colour image in conjunction with a pel pattern is modified to horizontally displace, or delay, a single colour component 54 of the colour signal by substantially one half pel relative to the remaining colour components. The component pels 44 displaying this image are offset half a pel in the opposite direction to bring the images back into alignment, but with the pel sites horizontally out of alignment. This single component can be vertically offset in a similar manner relative to the remaining colour components. The effect of this colour component offset is to increase the effective resolution of the output display device, as seen by the eye, without adding significantly to the complexity of the image generating apparatus.
