Patent CA-2154479-A1 (CA)
Inventor: KOIVUKUNNAS PEKKA
IPC: D21G1/02
Filed: 1994-11-23
Abstract: The invention concerns a method in the calendering of a paper or of an equivalent web material. In the calender, the web material (W) to be calendered is passed through nips (N1...N9) formed by a variable-crown upper roll (13a), a variable-crown lower roll (14a), and by two or more intermediate rolls (15a...22a) arranged between said upper and lower rolls (13a, 14a). The rolls (13a...22a) are arranged as a substantially vertical stack of rolls (12a). As the intermediate rolls (15a...22a), such rolls are used in which the form of the natural deflection line produced by their own gravity is substantially equal. The nip load produced by the masses of the intermediate rolls (15a...22a) and of the auxiliary equipment (167a) related to same is relieved substantially completely in the method, and an adjustable load is applied to the calendering nips (N1...N9) by means of the variable-crown upper or lower roll (13a, 14a) and/or by means of an external load (143a) applied to the upper or lower roll. The invention also concerns a calender that makes use of the method.

Title: Radio telephone system for minimizing co-channel interference utilizing geographic separation of signals and transmission power control
Inventor: RITZ MORDECHAI
IPC: H04B7/005
Filed: 1994-12-16
Abstract: A system for minimizing co-channel interference between transmission sectors at their common periphery. The system exploits the geographic separation of potentially interfering mobile transmitters (12) and utilizes transmission power control. The system employs sectored antennas in a combined frequency hopping, TDMA system wherein each subscriber in a particular sector is assigned a time slot in the system based upon that subscriber's geographic location within that sector. The transmission power in the sector is reduced during certain predetermined time slots and subscribers who are remote from the fringe of the sector are assigned to these power reduced time slots.  During up-link the transmission power for subscribers located proximal to the fringe are reduced to cause less co-channel interference between their signals and the signals from other subscribers in different sectors having the same time slot.

Abstract: A backup control system comprises a control package, a file package including a battery monitor and a flip-flop circuit, and a back board having a return wire which provides connec-tion/disconnection of the monitor terminal of the monitor.  The monitor checks a voltage of the monitor terminal at all times and outputs a reset signal to the flip-flop circuit when the voltage of the monitor terminal becomes lower than a reference voltage.          The return wire connects the monitor terminal to the power line when the file package is connected to the connection board, and disconnects the monitor terminal from the power line when the file package is removed from the connection board.  The flip-flop circuit stores one of a set state and a reset state, and changes in state from the set state to the reset state when the reset signal is received from the monitor.

Title: Higher order digital phase loop filter
Inventor: BHATT BHAVESH BHALCHANDRA
IPC: H04L27/00
Filed: 1994-01-12
Abstract: A higher order phase loop filter includes an integrator consisting of an adder (25) and a delay element (31) arranged in a feedback loop between the output port of such adder and one of its input ports. Signal to be filtered is applied to a second input port of the adder. A detector (30) is coupled to the output of the adder to detect limiting values, which, when detected, conditions the detector to reset the current value in the delay element of the integrator to a fixed value such as zero. Resetting the delay element momentarily lowers the order of the filter and speeds system response time in the presence of noise.

Patent CA-2186211-A1 (CA)
Inventor: HERSOM CHARLES
IPC: B64G1/36
Filed: 1996-09-23
Abstract: The present invention provides a method for distinguishing a boundary of an object, and the object itself, from its background. In the method electromagnetic radiation is detected from at least two fields of view substantially spanning the boundary of the object and background adjacent to the boundary and superimposed or overlaid as images onto a detector. The method includes correlating spatial transitions in intensity of the overlaid images on the detector with a boundary of the object. When used for determining the attitude of a satellite with respect to the earth, the detector is a thermal infrared detector thereby providing a sharp contrast between the thermal emission of the earth and cold space. The invention provides a simple, effective method and device for determining satellite orientation and/or attitude with respect to a thermal infrared-emitting target body.          The sensor includes a segmented limb-looking mirror to provide multiple fields-of-view within the field-of-regard and superimposing these fields-of-view as images onto a common detector. The required resolution can be obtained while providing a wide range of operational orbital altitudes. Multiple channels in a modular form provide redundancy, improved accuracy, and the opportunity of providing more diverse configurations. The utilization of uncooled microbolometer arrays as imaging detectors removes the requirement for additional cooling equipment thereby providing a low cost, small size and low mass sensor with configurational flexibility.
