Title: Driving apparatus for reporting states of light-emitting diode channels in a binary mode
Inventor: HUNG CHI-CHANG
IPC: G01R31/26
Filed: 2007-07-30
Granted: 2009-09-23
Abstract: A driving apparatus for reporting states of a light-emitting diode (LED) channels in a binary mode comprises a plurality of channel points (NCHm), at least one controller 112, a plurality of detectors 114, and a signal converter (fig 2, 130). The controller controls operation of the connected LED channels and the signal converter receives a detecting signal Sm generated by each detector 114 and corresponding to the state of the LED channel, and computes the received detecting signal to generate a report signal with N bits in a binary mode, wherein N is an integer greater than 1, and the number of the channel points is less than 2<N>. The number of channels is preferably greater than or equal to 2<N-1>. The detector 114 may comprise voltage comparators 115,116 comparing the channel voltage with voltage references Vrefo and Vrefs corresponding to error states such as an open circuit and a short circuit, and logic element such as gate 117 to aggregate the state into detecting signal Sm. Error states may also comprise over temperature or electric leakage and the controller 112 may comprise a switch SW1/SW2 and regulating unit 113 to control turn-on of the switch. The apparatus may drive the light emitting diodes of a LED area display, such as one used for image display.

Granted: 1983-10-12
Abstract: The valve assembly comprises a deformable plug (1) eg. of rubber, having a cylindrical body formed with a circumferential groove (5) and a pair of backing plates (2) and (3) located at either end of the plug (1). 
<??>The plates (2) and (3) are bonded to the plug (1) and, in use, plate (2) is moved to stress the plug (1) and cause it to expand radially to restrict an annular clearance between the plug (1) and a valve seat (not shown) in which the plug (1) is located. This enables fluid flow through the clearance to be controlled. A flanged steel ring (4) is mounted on the backing plate (2) and a circular neck portion (10) of the plug (1) is located between the ring (4) and the plate (2), the portion being bonded to the plate (2). The ring (4), and expecially the groove (5), serve to prevent or inhibit erosion of the plug surface in use.

Title: Smoke producing target rocket
Inventor: CAMPAGNI ALDO
IPC: F42C/
Filed: 1985-03-22
Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.

Patent NL-179097-B (NL)
IPC: G11C29/32
Filed: 1976-09-30
Abstract: A read/write memory of n stages, periodically addressed in a recurrent scanning cycle of n time slots in which binary words are written in and read out from respective stages, is connected to a data-handling network by way of a writing multiple and a reading multiple each traversing a respective selective inverter, i.e., an upstream inverter in the writing multiple and a downstream inverter in the reading multiple. The two inverters are controlled by a generator of pseudo-random binary signals, unrelated to those processed in the data-handling network, having an operating cycle coextensive with a scanning cycle. Depending on the character of the control signals issuing from this pseudo-random generator during each cycle, the two selective inverters pass the bits of their incoming words either in their original or in a complemented form; with words written in a memory stage in one cycle read out in the immediately following cycle, the control signals delivered to the two inverters are identical but staggered by one cycle so that the words appearing in the output of the downstream inverter match those fed into the upstream inverter in the preceding cycle when the memory operates properly. Under certain circumstances, when a memory stage is addressed out of turn so that loading and reading of its contents occur successively in the same cycle, the staggering of the two control signals is canceled. Malfunctions of the memory are detected by parity checks carried out on the words traveling along the reading multiple to the downstream inverter; an alarm signal is emitted upon the occurrence of an error in the same bit position in two consecutive cycles.
