Title: Shading correcting method
Inventor: YAMANOUE MASAFUMI
IPC: G06T1/00
Filed: 1990-03-02
Granted: 1995-08-01
Abstract: The shading correction is performed with respect to a signal "A" indicative of the image density read by an optical read device in accordance with a reference signal "B".  Both the signals "A" and "B" consist of n bits.  An inputted signal having an initial value "A" is doubled by a multiplier when A?B and B?0.  A subtracter subtracts the reference signal "B" from a signal "X" outputted from the multiplier and discriminates whether or not a signal "X-B" is negative.  An S/P conversion register doubles an inte-grated value "S" having an initial value "0" and changes the integrated value from "S" to "2S" when the signal "X-B" is negative.  In contrast, when the signal "X-B" is not nega-tive,  the S/P conversion register adds  "1"  to  "2S"  and changes the integrated value from "S" to "2S+1".  The signal "X" outputted from the multiplier is again inputted into the multiplier when the signal "X-B" is negative.  Alternative-ly, the multiplier receives the signal "X-B" outputted from the subtracter when the signal "X-B" is not negative.  The above procedure is repeated n times.  The last integrated value outputted from the S/P conversion register is equal to or approximately equal to a value obtained by an expression "S=A(2n-1)/B", and therefore, the former can be regarded as a shading correction signal.

Title: Time-division multiplex communication system with a synchronizing circuit at the receiving end which responds to the coding of words inserted in the transmitted information
Inventor: WEIS BERND X
IPC: H04L5/22
Filed: 1990-07-03
Granted: 1996-05-21
Abstract: There are TDM communication systems in which synchron-ization is accomplished by means of code words which are transmitted at regular time intervals and coded in a particular code. In systems where the signals are trans-mitted in packets of uniform length, each of the code words contains the information of the so-called header of a packet. The checking device according to the inven-tion successively checks all n-bit bit groups (Xj to Xj+n-1) beginning with any one (Xj) of the successive bits of the received bit sequence as to whether they are coded in a particular code. This is done by calcu-lating the syndrome (S1 to Sn-k) in several networks (N1 to Nn-k) which operate in parallel and each of which calculates one syndrome component. The received bit se-quence is delayed until the networks have calculated the syndromes for a given n-bit bit group and until a syndrome evaluation circuit (LS) indicates whether the bit group is a code word.

Abstract: ABSTRACT OF THE DISCLOSURE A space frame comprises, in combination, a plurality of node members interconnected by a plurality of frame members, each frame member having at each end thereof an axial opening and a slot extending from each end and having a width which is less than the width of the opening, each node having a node body having a plurality of connectors extending radially outwardly from the outer surface of the node body for coaxial reception within an opening of an associated frame member, each connector having a cross sectional width which is smaller than the width of the slot so as to enable the connector to pass through the slot when disposed in edgewise alignment therewith and a cross sectional length whichis greater than the width of the slot and less than the width of the opening so as to prevent the connector from passing through the slot when disposed in other than edgewise alignment while permitting the connector to be rotatably received in the bore, whereby the frame member may be installed onto the connector by aligning the slot with the width of the connector and moving the frame member so that the connector passes through the slot and the connector may be retained within the frame member by angularly displacing the frame member to a position whereat the connector is not edgewise aligned with the slot.

Title: Modular ski rack and mounting kit
Inventor: CHIAROT JOHN B
IPC: A63C11/00
Filed: 1990-12-14
Granted: 1996-02-20
Abstract: A modular ski hanger system and kit for mounting the same, is provided with a bracket member which may be mounted on a vertical surface.  Ski hanger modules, which may be slidably mounted on the bracket member, each have an upright thickened back portion and a pair of substantially parallel upright wall members forwardly projecting from the back portion. The wall members are spaced apart by enough distance to permit insertion of a pair of typical skis arranged base-to-base at a portion adjacent their curved front ends, and the wall members have a dimension parallel to the back portion which is great enough to ensure that the pair of typical skis received between them will be maintained together by the wall members without slipping down.  This allows two ski hangers to be positioned with one inverted with respect to the other, allowing close spacing of the skis.  A cylindrical plug member may be inserted through opposed apertures in the wall members of a module in order to provide abutment means to retain the pair skis in the module against forward lateral sliding.  Apertures of adjacent inverted modules are substantially aligned so that locking means may be threaded along the length of a series of modules to lock all skis in place, or alternatively, a single locking means may be inserted through a lateral aperture in the plug member to prevent removal of the plug member from the module.

Title: Handoff procedure that minimizes disturbances to dtmf signalling in a cellular radio system
Inventor: DAHLIN JAN ERIK AKE STEINAR
IPC: H04W36/08
Filed: 1991-10-08
Granted: 2001-08-07
Abstract: Disturbances to DTMF signaling between mobile stations and the land-based system caused by handoff are minimized. DTMF signals are transmitted in real time between a mobile station and its associated base station. However, if during a DTMF transmission between a base station and the mobile switching center a handoff is requested, the handoff is delayed by a specified time in order to allow completion of the DTMF transmission. Alternatively, both base stations involved in the handoff transmit overlapping DTMF tones until the handoff is completed. If the handoff is requested before the start of the DTMF tone transmission, the DTMF transmission is delayed until the handoff is completed.
