摘要： A digital radiography (20) detector has a first housing (18) having substantially the form factor of a film cassette and having a chest wall edge (C). The first housing (18) has an X-ray converter (70) with a detection array (26), each detector generating a signal according to an amount of radiation received. Readout electronics (74) are coupled with switching elements in the detection array for obtaining the signals therefrom. The readout electronics (74) include elements formed from crystalline silicon and are distributed toward outer edges of the first housing (18) and away from the chest wall edge (C). X-ray shielding selectively protects the readout electronics (74) and is located beneath a portion of the detection array. A second housing (40), electrically connected to the first housing (18) has a power source for the detector, readout and control electronics for obtaining signals provided from the detection array (26).

摘要： A replaceable modular opto-mechanical unit includes a light source in the form of, for example, a laser assembly; an optical modulator assembly which modulates light from the light source; and a lens located in a light path between the light source and the optical modulator assembly. The lens focuses the light from said light source toward a center of the optical modulator assembly. The unit further includes a base adapted to removably support the light source, the optical modulator assembly and the lens in an optically aligned manner. The base is further adapted to be removably attached onto a receiving structure of a printer, such that an attachment of the base having the optically aligned light source, optical modulator assembly, and lens supported thereon, permits light from the optical modulator assembly to be focussed onto an optical element of the printer.

摘要： An athermally compensated printhead includes a laser diode having predetermined characteristics for generating a beam of light, a diode mount, cooling means, a collimator lens, and a len mount. The diode mount is formed of a predetermined material with a predetermined coefficient of thermal expansion for mounting the laser diode in the printhead. The cooling means is used to maintain the laser diode at a substantially constant operating temperature for longer life and to avoid wavelength changes. The collimator lens has characteristics which provide predetermined changes in focal length versus changes in ambient temperature over a predetermined temperature range. The len mount is formed of a predetermined material having a predetermined coefficient of thermal expansion for mounting the collimator lens adjacent a first major surface of the diode mount to receive the beam of light from the laser diode. The predetermined coefficient of thermal expansion of the material of the lens mount is chosen to compensate for the changes in focal length of the collimator lens versus changes in ambient temperature over the predetermined temperature range.

摘要： A relatively inexpensive coupling for preventing the transmission of thread drunkenness to a carriage or other element being driven by a lead screw. The coupling is formed with an input plate and an output plate both connected to an intermediate member. The connections via flexure members permit movement of the intermediate member relative to the coupling and the output plate to provide uniform motion to a carriage along the lead screw axis.
