A reading apparatus has a sensor unit which is arranged on a substrate to read an object to be detected, a driver circuit unit which is arranged on the substrate to supply a drive signal for driving the sensor unit, and a static electricity protection portion, which is formed to cover at least a portion of the upper surface of the driver circuit unit, and at least a portion of which has electrical conductivity.

Disclosed is a reading lens consisting of one glass lens and first and second plastic lenses. A positive diffraction lens structure being is formed on one surface of the surfaces of the first and second plastic lenses. The positive diffraction lens structure functions at least to compensate a longitudinal chromatic aberration which is caused by refractive power of the glass lens and the first and second plastic lenses.

A system (11) for presenting textual and/or graphical information for reading. The system includes a visual display unit (15) for displaying the textual and/or graphical information within a general layout screen, a microcomputer including processing means (13) to receive the textual and/or graphical information in an electronically encoded form and process the same for presentation on the visual display unit (15). A computer program (19) is provided for controlling the presentation of the textu...

An apparatus and a method for assisting a child to read a book having at least one visual indicia displayed adjacent one or more of the plurality of printed objects. Each of the at least one visual indicia is uniquely associated with the adjacent one of the plurality of printed objects. The device includes a user input device separate from the book having at least one touch-sensitive switch and at least one visual indicia displayed thereon for receiving a user command indicative of a user's sele...

A hammock is described that has a concave across the mid portion of its hammock bed, a rigid curved bar extending between opposite sides of the hammock bed, beneath its concave, and a flexible strap extending taut between opposite ends of the rigid curved bar beneath the concave.

A portable reading machine has a scanner for scanning an image comprising text. The scanner has a scanning area occupying a maximum width and an active width defined by a scanning width limiting mechanism adjustable to a preselected width. A photoreceptive element forms an electronic representation of a portion of the image within the active width. The electronic representation is converted to a digital character string corresponding to the active image text. A speech system outputs the digital ...

A reading pen for reading text has an elongate casing with a reading opening (3) formed in one end thereof, a printed circuit board (5) which is arranged inside the casing, light-emitting diodes (7a, 7b)) arranged inside the reading opening and adapted to illuminate the text that is to be read, and a light-sensitive sensor (9) arranged inside the reading opening and adapted to read the illuminated text. The printed circuit board (5) has an end portion at said one end of the casing. The end porti...

Colored markings such as a series of colored rings applied to an ampoule are read by causing the ampoule to move beneath an illuminating system which projects white light at the colored markings. Light reflected or scattered from the colored markings is directed at an aperture member arranged in the field of view of a color sensitive photoelectric detector arrangement and the image of the colored markings moves in a first direction across this aperture member due to relative movement of the obje...

A pattern reading device comprises feed mechanism for storing a sheaf of cards carrying patterns and feeding said cards one by one, a conveying mechanism having a plurality of pinch members at regular intervals to pinch the forward edge of each fed card and convey said card to a reading section, and an optical reader provided in said reading section for reading patterns on said cards.

The disclosure relates to a method and device for reading data in the form of data pulses in a pulse train. The pulse train is obtained by the sensing of a flexible disc and contains, conventionally, a sequence of clock pulses which, in at least a portion of the pulse train, define mutually subsequent bit cells. These contain at most one of the data pulses. A bistable circuit is switched to its one state by the clock pulses and switched to its other state by the data pulses. The time which has e...
