Abstract: A fast data alignment display queue structure for image block transfer comprises a shift circuit, a bit mask, a multi-layer FIFO buffer and a plurality of multiplexers, wherein input data are shifted a desired number of bytes by the shift circuit, and written to the FIFO buffer, and then the data in each level of the FIFO buffer are read by an external DRAM. By using the structure above, a block can be shifted to right or left by filling the data to the FIFO buffer in the sequence started from the first level or in the sequence started from the last level. Therefore, shifting operation for a block can be implemented in different directions without additional transfer logic.

Abstract: A computer mouse for blind users and a method for its use. The mouse has a display area on its upper surface in which a portion of the computer's screen display is reproduced in tactile form, for example by raising and lowering members of an array of pins. A monochrome display is encoded by pin height. A color display may be encoded in various ways. Preferably, lightness is encoded as the range of vertical motion of the pins and hue is encoded as pin motion frequency. A blind user scans the screen display by moving the mouse around on a mouse pad and feeling the relative heights and frequencies of the pins.

Abstract: The present inventions relates to a mold for forming a one piece flip-top cap and process for making such a cap. A mold for forming and closing the one piece flip-top cap prior to ejection from the mold includes a first mold part, an inner core mold part and a second mold part movable into relationship with the first mold part and the inner core mold so as to form a mold cavity therebetween. The mold produces a one piece flip-top cap with a living hinge between the body and lid of the cap and which is maintained in a closed position upon ejection from the mold. Pull straps are used to ensure full closure of the cap lid to the body prior to ejection.

Abstract: A device for connecting two drum pedals of a drum includes an outer tube, an inner rod and a resilient strip. The outer tube defines therein an axial hexagonal (tetragonal) hole. A first end of the outer tube forms a recess on a periphery thereof having a plurality of screw holes and a through hole defined from a circumference of the outer tube to the outer surface of the recess. The inner rod is received in the hexagonal hole of the outer tube and defines a cutout in an appropriate position of a circumference thereof. The resilient strip is received in the recess of the outer tube and abuts the inner rod. A first end of the resilient strip has a protrusion integrally extending from one end thereof to be received in the through hole of the outer tube and a second end of the resilient strip is retained by the cutout of the inner rod. With this arrangement, the device for connecting two drum pedals can prevent damage to the inner rod and separation from the outer tube.

Abstract: A device for measuring distance between walls of coaxial cylindrical screens is provided. Rotation of motors is rotated to screw bars and rotation of the screw bars is converted to translational movement of gauge bars. The numbers of rotation of the screw bars corresponding to length of projection of the gauge bars from their withdrawn positions to positions at which they abut against wall surfaces of the screens are measured by rotary encoders and the distance between wall surfaces of the screens thereby is measured. A main body of the device is fixed between the wall surfaces of the screens by means of the projecting gauge bar and a pair of main body supporing units.

Abstract: A method for enabling traditional SCSI peripheral equipment to be compatible with a PLUG-AND-PLAY protocol comprising steps of: selecting an SCSI peripheral device as an object and assigning a predetermined identification number to the selected SCSI peripheral device; periodically detecting the signal status on an SCSI bus so as to change a specific signal level to thus communicate with a host computer which determines whether the assigned identification number is permitted; and delaying a time period during the detection of the signal status on the SCSI bus when the permission to assign an identification number has not been determined, and abandoning the assigned identification number when the same identification number has been found to be used by another SCSI peripheral device.
