Title: Varying bandwidth digital signal detector
Inventor: MYER ROBERT E
IPC: H04J1/00
Filed: 1990-10-11
Granted: 1994-08-02
Abstract: A digital communication system has a plurality of channels with distinct carrier frequencies and overlapping bands. Each receiver includes a filter having a time varying bandwidth. The received signal includes at least one carrier modulated by an information signal having a plurality of levels and transitions between the levels at predetermined intervals and components due to other channels. The receiver is synchronized to a selected one of the carriers. The received signal is translated to baseband and applied to the time varying filter which is set to a first bandwidth at the information signal transitions and reduced in the intervals between transitions. The first filter bandwidth accommodates the information signal transitions. Reducing the bandwidth between transitions limits interference components in the time varying filter output when the the information signal level is sampled. The technique may be applied to various modulation schemes.

Title: Optical transmission network with frequency locking means
Inventor: VAN DEVENTER MATTIJS O
IPC: H04B10/155
Filed: 1991-09-10
Granted: 1994-10-18
Abstract: Frequency stabilizing in a, for instance star/branched-tree shaped, network can be well executed by locking the frequencies (f1) of the transmitters (T1) in the network centre to a common reference frequency source (CFC) and, moreover, per duplex connection, locking (at a fixed frequency distance) the frequency (f2) of the subscriber's transmitter (T2) to the transmission signal (t1) as received from the network centre's transmitter (T1). Per duplex connection only the subscriber's local oscillator (L2) has to be tuned so that the transmission signal from the network centre is received optimally. If the subscriber's local oscillator is tuned thus and the subscriber transmitter's frequency has the right frequency offset to the tuned local oscillator frequency (f4), at the network centre's side, signals from the subscriber's transmitter will be received optimally too if the local oscillator (L1) of the network centre's receiver (R1) is set at a certain (predetermined) frequency offset to the signal transmitted to the subscriber's receiver.  Frequency setting, at the network centre's side and at the subscriber's side, can be executed by means of auxiliary receivers (R1a,R2a) and AFC-units, generating the various frequency control signals, or by means of the receivers (R1,R2) already in use, provided with multiple pass filters and AFC-units. For achieving relative low IF frequencies, certain frequency orders are preferred.

Title: Information processing apparatus having a floating-type head with a bevelled slider
Inventor: WADA KATSUO
IPC: G11B7/12
Filed: 1992-02-28
Granted: 1997-07-08
Abstract: An information processing, i.e. reproducing and recording, apparatus which has a rotative driving means for rotating a disk-shaped recording medium, a floating-type head for reproducing information recorded in the recording medium while floating above the disk-shaped recording medium that is being rotated by the rotative driving means, and a suspension, made of an elastic member, for supporting the floating-type head. The floating-type head has a slider which is floated by an air flow that is directed near the surface of the rotating disk-shaped recording medium. The slider has a bevelled portion at one side that faces the outer edge of the disk-shaped recording medium, such that any contact between the slider and the ridge that exists along the outer edge area of the disk-shaped recording medium is virtually eliminated. Since the slider virtually avoids contact with the ridge that exists along the outer edge area of the disk-shaped recording medium, the storage capacity of the disk-shaped recording medium can be more effectively used.
