Abstract: A scanning imager is described which includes a line camera (26) and a table (12) to mechanically present successive regions of an item to be imaged. The time of exposure of the camera for each successive region presented is controlled by encoding strips (18, 20) connected to the table. Thus, if the table is subjected to motion variations, the encoding strips are likewise affected and vary the exposure time for each analog image pixel scan. To compensate, an exposure correction system is provided which includes an analog voltage generator (56) whose output is related to each successive region exposure time. An A to D conversion circuit (62) is responsive to the analog voltage to normalize the analog image value from the camera so that, in effect, equal exposure images result.

Abstract: A method of programming a programmable hearing aid is disclosed. The programmable hearing aid has a serial data interface for receiving data transmissions, a decoder for decoding data transmissicns, a program memory which stores program data values received via the serial interface, and read control logic that transmits the program data stored in the program memory when the decoder detects the receipt of a predefined read signal. Programming begins with the sending a set of program data values to the programmable hearing aid, preceded by a predefined write signal. The hearing aid automatically mutes or inhibits its operation upon receiving the write signal. A first checksum value corresponding to the program data values sent to the programmable hearing aid is calculated. Next, the data stored in the hearing aid is checked by sending a predefined read signal to the hearing aid, causing the hearing aid to transmitting the program data stored in its program memory. A second checksum value corresponding to the program data transmitted by the hearing aid is calculated and compared with the first checksum value. If the first and seccnd checksum values do not match an error signal is generated and the hearing aid remains muted. If the checksum values do match, an unlock signal is sent to the hearing aid, causing the hearing aid to resume normal operation.

Abstract: A half-duplex digital speakerphone (10) includes a control state machine which controls the selection of either a transmit or a receive audio path based upon a present state of the speakerphone and the magnitudes of three signal related variables associated with each path. The three variables for each path includes a signal power variable, a noise power variable and a worst-case echo variable. A change of state of the state machine results in the value of a variable gain within each of the paths being adjusted to optimize the transition time from the receive to the transmit state or from the transmit to the receive state. Also optimized is a change of state from an idle state to a transmit or receive state or from a transmit or receive state to the idle state. A change of state is accomplished in accordance with a smoothly varying, substantially Gaussian switching waveform which is selected to optimize the transition time between states while simultaneously minimizing audible side effects.

Abstract: For controlling a group of relays in a low-power manner, a lower latching voltage and, for a short time in each case when switching on an additional relay, an increased actuating voltage are generated via a voltage regulator (VC) in normal operation. The switching-on of an additional relay is detected as a current rise by means of a current measuring device (RS, OP1) and is evaluated to generate a regulation signal (i) for the voltage regulator (VC). 
<??>In this way, the operating voltage can be regulated in a simple manner for any number of relays which can be individually switched on and used at different sites, such that no excessive heat loss occurs. Since there is no need for either a state measurement or individual voltage regulation, the cost of both sensor leads and circuit elements is low and, in particular, is independent of the number of relays.

Abstract: Methods and compositions for producing materials which exhibit high temperature superconductivity. The material produced using the present invention is high in purity and is able to exhibit superconductivity at temperatures above those obtainable by liquid nitrogen. The present invention discloses techniques for fabricating ceramic superconducting materials of the type having the general chemical formula MBa₂Cu₃O 7-x , using an aqueous coprecipitation process. 
     According to the teachings of the present invention, the metal components of the superconducting material are first placed in solution. The ratios of the various components are carefully chosen so that the final product has the desired stoichiometric ratio. 
     The solution pH is adjusted by the addition of a basic solution which contains only volatile components. That is, pH is adjusted in such a manner that the pH adjustment does not leave residue of any type in the final superconducting product after the product is   heated, sintered, or calcined. Accordingly, ammonium hydroxide, ammonia gas and urea are generally preferred for adjusting the pH.
