Inventor: BELL CYNTHIA SUE EASTMAN KODAK
IPC: H05B33/12
Filed: 1989-10-16
Abstract: In the present invention a matrix array of organic electroluminescent storage display elements along with row and column selection circuitry (12, 14, 16) are used to select the particular display elements (40) within the matrix to be illuminated. Interposed between the column and row selection electronics are a plurality of memory cells (22) receiving as inputs bit values (B n -B o ) that correspond to the desired intensity requested from a display element (40). The memory cells (22) output activation signals which drive corresponding MOS switches (24) each of which in turn is parallel connected as part of a current driver source (28) feeding a single display element (40). Activation of one or more of the MOS switches (24) provides a controlled amount of current to be applied to the display element (40) to in turn provide a related amount of light from the display element (40).

Abstract: The vibrator includes a columnar vibrating body (20) consisting of a piezoelectric material. The vibrating body (20) is formed into a polygonal or cylindrical column and when necessary, a through hole (64) is formed axially thereof. Furthermore, the vibrating body is polarized. On side faces of the vibrating body, at least, three external electrodes (24a,24b,24c) are formed. Also, when the through hole (64) is to be formed, an internal electrode (66) is formed on its inner circumferential surface. By applying the driving signal to these electrodes, the vibrating body (20) bends and vibrates. And, when the rotational angular velocity is applied to the vibrating body (20) about its axis, a coriolis force is produced responsive thereto. By this coriolis force, the vibrating direction of the vibrating body (20) changes, and a voltage is produced between the two external electrodes. By measuring the voltage, the rotational angular velocity applied to the vibrator (20) can be measured.

Abstract: An Inverse Multiplexer is disclosed which first demultiplexes a first data rate input signal into a plurality of second lower data rate subsectional signals, where each subsectional signal is provided with a periodic synchronization marker and includes a data rate which is less than the channel data rate used to transmit that subsectional signal to a remote terminal. Programmable Multiplexers (PMUXs) then operate to each take one or more subsectional signals that are (1) clock synchronized to a PMUX clock, and (2) a rational fraction of the channel data rate, and map contiguously assigned time slots in a capacity domain frame for each subsectional signal to time slots of a time domain frame format using a 2-step or 3-step digit reverse technique. The resultant time domain format has the input subsectional capacity domain time slots substantially uniformly distributed over the time domain frame. At the receiving end, an Inverse Demultiplexer performs the reverse operation to recover the original first data rate input signal.
