Patent CA-2316177-A1 (CA)
Title: Frame-synchronizing-signal capturing circuit of receiver
Inventor: SHIRAISHI KENICHI
IPC: H04J3/06
Filed: 1998-12-11
Abstract: A demodulator (1) produces I and Q symbol streams from a received PSK signal which is a time-multiplexed signal composed of a 20-symbol-long BPSK frame sync signal, a 20-symbol-long BPSK superframe identification signal, and an 8PSK digital signal. BPSK demappers (3) produce bit streams B0-B3 demapped according to a base criterion, which allows signal points to be the same along the Q-axis in the I-Q phase plane, and to criterions obtained by shifting the base criterion counterclockwise by .pi./4, 2.pi./4 and 3.pi./4. First comparators (60-63) capture, from the bit streams B0-B3, patterns being different few bits at most than the frame sync signal. A predetermined time later, second comparators (64-67) capture patterns being different few bits at most than the superframe identification signal. A frame sync capture signal (SYN) is then produced by a generator (90).

IPC: A61G12/00
Filed: 1999-03-22
Abstract: An apparatus (20) for supporting a service column (28) from a ceiling (26) includes a mounting assembly (22), an arm assembly (24), and a leveling mechanism (270). The mounting assembly (22) is adapted to be coupled to the ceiling (26) and includes a tube (46) configured to extend downwardly with respect to the ceiling (26). The arm assembly (24) includes a first arm (30) coupled to the tube (46) and extending therefrom. A portion of the arm assembly (24) is adapted to be coupled to the service column (28) so that the service column (28) is supportable at a location spaced from the mounting assembly (22). The first arm (30) is subject to loads having a tendency to deflect the first arm (30) relative to the tube (46). The leveling mechanism (270) includes a first member (272) engaging the tube (46), a second member (274) coupled to the first arm (30), and an adjuster (276) coupled to the first and second members (272, 274). The adjuster (276) is movable to move the first member (272) relative to the second member (274) thereby to move the first arm (30) relative to the tube (46) to compensate for deflection of the first arm (30).

Title: Record carrier, playback device and method of recording information
Inventor: TALSTRA JOHAN C
IPC: G11B7/24082
Filed: 2000-01-10
Abstract: A record carrier has substantially parallel tracks, which exhibit first variations of a first physical parameter and second variations of a second physical parameter of the track. The first variations represent information recorded on the record carrier, which information is recoverable by means of a controllable type of data processing. A modulation pattern of the second variations represents a code for controlling said type of data processing. In respect of a code track that comprises the modulation pattern, the modulation pattern in the left neighbouring track (41, 44) is aligned to the modulation pattern in the right neighbouring track (43, 46). Thereby crosstalk due to the second variations is decreased, and at least two tracks have the same modulation pattern. The playback device has a demodulator and a control unit (56) for retrieving the code from at least two tracks.

Title: Method and system for providing an appliance user interface
Inventor: BARTLETT GREGORY J
IPC: H04N7/24
Filed: 1999-05-11
Abstract: A method and system for providing user interfaces for controlling various media appliances through a master device. The user interface system allows media appliances to provide executable code that implements their user interfaces to a master device that can execute the user interface code. To provide an appliance-specific user interface, the master device first identifies the appliances that are connected to the master device, for example, via a bus. The master device then displays an indication of each of the identified appliances to a user. The user can then select one of the displayed appliances that is to be controlled or monitored. In response, the master device retrieves from the selected appliance the user interface code that may be customized to the selected appliance. The master device then stores the retrieved user interface code in memory. The master device can then execute the stored user interface code to control and monitor the selected appliance.

Patent CA-2333325-A1 (CA)
Title: Trunk management system for telecommunications
Inventor: MARTIN ANDREW LOUIS
IPC: H04L12/24
Filed: 1999-05-26
Abstract: A system is dislosed for allowing the stations of a telecommunications trunk to communicate with one another, and with a control centre, using IP addresses and packets on the trunk service line. This is effected by the use of service packets or headers having short (preferably single-byte) station addresses so that the service packets can be routed by low-level routines without the need to buffer or examine each IP packet. When the service packets reach their destinations, the IP packets can be extracted and processed by IP-capable remote site controllers at each station. As a result, communication between the control centre and any station can be conducted transparently using higher level protocols such as SNMP/UDP/IP. A method of monitoring alarms at trunk stations using this communications system is also disclosed.

Abstract: A method of geophysical exploration using seismic methods. The receivers and the source are rotated to one another, such that the orthogonal excitations of the seismic source are readily differentiated.
