Abstract: Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks (106, 108 ... 110). Each block contains N symbols wherein M of the symbols (102) comprise information to be transmitted and the remaining N-M of the symbols (104) comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks (106, 108 ... 110) in the data stream are divided into a succession of frames (144, 146, 148, 150, 152, 154), each comprising F of the coded blocks. A frame overhead symbol (112) is added for each of the frames, to provide data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second information rate M'/N', where M/N = (M' + b)/(N' + b) and b is an integer chosen to provide the second information rate at a desired value. N is less than 2<n> + 1, where n is the number of bits in each of the symbols. The number of coded blocks F in each frame is determined from the relationship F = M'P/(N-M)b. P is the smallest value integer that will render F an integer, and is also the number of overhead symbols added per frame. A plurality of X of the frames are formed into a superframe (100) containing FX coded blocks and PX frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function. <IMAGE>

Title: Plate casing having sealingly-mounted through insulators and manufacturing method.
Inventor: VAGHINI ALBERTO
IPC: H01B17/30
Filed: 1995-05-11
Abstract: A method of sealingly mounting electric insulators passing through a plate wall, in particular for the manufacture of a housing case (10) for electric disconnecting switches, comprises the steps of making a collar (14) projecting from the plate at a passage hole (13) for the insulator; fitting the insulator (12) into the hole in the direction of the collar (14) projection so as to bring, upon interposition of a seal (18), an abutment edge (15) radially projecting from the insulator against an edge of the hole on the side opposite to the collar projecting side; bending the free end of the collar inwardly, forming a locking angle and forcing said end into a circumferential seating (16) present in the insulator surface so as to prevent the insulator from being withdrawn from the hole. In this manner a plate casing (10) for an electric apparatus is achieved which has an excellent tightness between the casing wall and the insulators passing therethrough. <IMAGE>

Abstract: A small-sized arrangement for a circuit breaker includes
at least one DC circuit breaker (1a, 1b, ..., 1k), a parallel
impedance means with a suitably determined inductance (L) and
a suitable capacitance (C), and an energy-absorbing element
(4). The parallel impedance means has a parallel reactor (3)
of a carefully selected inductance and a parallel capacitor
(2) of a smaller capacitance value. Determining the
reactance and capacitance values of the parallel reactor (2)
and parallel capacitor (3) to satisfy certain conditions can
cause the DC circuit breaker (1a, 1b, ..., 1k) to take full
advantage of the inherent performance. The interruption time
remains minimal, thereby achieving enhanced interruption
performance. Since the capacitance (C) of parallel capacitor
(3) is rendered relatively smaller, the device can be small
in size and low in cost.

Abstract: A method and system (20) is described herein for adaptively
adjusting the transmission power and code rate for a transmitted
signal to compensate for high bit error rate for the signal
at a receiver (22). In particular, the method comprises establishing
a threshold bit error rate for the signal received
in the receiver (22), calculating the bit error rate of the
signal received in the receiver (22), transmitting information
indicative of the bit error rate to the transmitter (21), and
decreasing the code rate of the signal at the transmitter (21)
if the bit error rate is higher than the threshold bit error
rate. Prior to adjusting the code rate of the signal, the
transmission power of the signal can be increased to attempt
to improve the uplink signal strength. The system (20) comprises
a transmitter (21) including a coder (31) for transmitting
forward-error-corrected bits in a signal, a receiver (22) for
receiving the bits, and an independent backlink (30) allowing
communication between the receiver (22) and the transmitter
(21) relating to fading conditions at the receiver (22).

Abstract: A self-verifying identification card having an image
area which may contain a portrait, a finger print, a
retinal image, or all of these together with an image
signature which is derived from scanned intensity
measurements taken from the image area. In the
verification process, the image is scanned and aligned
with respect to reference points corresponding to the
original printing process which created the card, and
intensity values, their averages, or any other function
are compared to information provided by the image
signature. Mathematical transformations, such as a one-way
hash, an encryption, a compression algorithm, or a
truth table may be used to encode the image signature.
Alignment markers aid in scanning the image and the image
signature. The use of average values aids in reducing
noise and the use of comparison functions makes the
process less sensitive to variations among scanners. The
verification may be done at the point of a transaction,
for a standalone system, or may be referred to a
centralized data base in a networked system for further
inquiry. In a networked system the image signature may be
stored in the database.
