Abstract: A material removal system may control movement of a material removal machine based on whether a material removal tool is in contact with a sample. A material removal system may include a material removal machine (e.g., saw, grinder, polisher, and/or more general material preparation and/or testing machine) that is configured to move at the urging of one or more actuators. The system may further include control circuitry configured to control movement (and/or speed, acceleration, etc.) of the material removal machine (e.g., via the actuators) based on one or more power, thermal, position, and/or other parameters that indicate whether the material removal tool of the material removal machine is in contact with a sample.

Abstract: Door/lid operated page turner devices, systems and methods for reading materials such as books is provided for hands-free reading for the able-bodied and disabled reader. A platform supports a book that is covered by a bottomless box having an open top, with left and right transparent lids slidably attached to cover the open top with a small space between the lids when closed. A single protruding member with a tip is adapted to slide the right transparent lid to the right exposing a page of the stacked reading pages, the tip is also used to lift up an outer edge of the page to be above the right transparent lid, followed by the tip of the protruding member pushing against and sliding the right transparent lid to the left until the right transparent lid abuts against the spacer, wherein the tip of the protruding member pushes both the closed left and right transparent lids to the left until the raised first page is turned and overlaying the left portion of the supporting platform.

Abstract: Described is a bookmark having a bookmark body, on which a bookmark clip is disposed. The bookmark clip can clam the cover or inner pages of a book to prevent the bookmark body from falling off from the book. The bookmark body is bendable and includes a protection surface of mounting the bookmark clip, a bendable surface and folding sheet capable of being inserted into content pages of a book. The bookmark can be repeatedly used for many times while having the features of being simple in structure, easy to manufacture, and flexible and convenient to use.

Abstract: A reading item supporting system is provided including a reading item support for supporting a book thereon. Also included is at least one ruler assembly positioned on the reading item support with the book therebetween. The ruler assembly includes a ruler strip adapted to move downwardly an incremental distance upon the actuation.

Abstract: The present invention provides a copyholder having a ratchet mechanism including a flexible rack attached to a line guide with the rack being operable by a pawl which is moved by a foot operated actuator functioning through a cable to move the line guide in discrete steps the magnitude of which are adjustable. Manual adjustment of the line guide is permitted when the ratchet mechanism is in an inoperative position.

Abstract: An improved text scanning apparatus is disclosed. A support structure retainably holds a sheet of material to be scanned in snug planar engagement with an upright copyboard support surface. Light sources selectively enable illumination of the sheet from overhead or through the sheet. Horizontally and vertically movable masks overlie the sheet material and traverse over the material in precise operator preselected incremental timed manner, to highlight the text according to the operator's selections. The system provides for full automatic, semiautomatic or manual modes of operation.

Abstract: A line-guide advancement mechanism for copyholders of the type for holding a document containing information to be transcribed and containing a linearly moveable line-guide for highlighting individual lines of information. The line-guide advancement unit is structured to be able to fixably attach to an existing copyholder (10) and a line-guide (46). The unit contains a drive mechanism (12) and an operator's foot pedal (20) which provide step-wise movement to the line-guide (46). The drive mechanism (12) can be adjusted via a knob (36) and vernier scale (74) to provide a wide range of spacings in the movement of the line-guide.

Abstract: An apparatus wherein a line reader support housing is mounted to an articulated framework that in turn is securable to a support table. The line reader housing includes a transparent reader bar in operative relationship with a step motor to effect vertical repositioning of the reader bar relative to an underlying sheet member.

Abstract: A copy stand for shifting a cursor by a motor one line on a copy at a time in which a cursor holder is coupled to bend slightly and sandwich an endless belt driven by the motor. At the driving time by the motor, a coupling force works strongly by a tension of the belt to shift the cursor by the motor and when the cursor is to be returned to its upper end, the cursor can be easily shifted manually while the belt is stopped.

Abstract: An electrically controlled copy holder includes a face plate defining a copy support surface and a line guide extending across the face plate and slideably mounted adjacent one vertical edge of the face plate, for vertical sliding movement along the copy support surface. The line guide is attached to a motor driven endless belt mounted in a housing on the opposite side of the face plate. Electric control means are provided for maintaining the motor energized for an adjustable interval, and hence for moving the line guide a pre-selected distance.

Abstract: An electrically operated copyholder is disclosed wherein a line guide extending transversely of copy matter supported on a face plate is removably mounted on an endless driving element, such as a belt, which is driven by a motor controlled by a typist, thereby to move the line guide automatically across the material to be copied line by line.
