Title: A planting machine
Inventor: ROY ERIKSSON
IPC: A01C11/00
Filed: 1998-01-21
Abstract: When planting plants and similar objects a forest vehicle (1) is used which is provided with automatic planting assemblies (13) mounted at hydraulically controlled arms (11). The vehicle (1) moves slowly forwards and the absolute geographic position thereof is determined by means of satellite signals received on the antenna (15). At the frontmost portion of the vehicle (1) on a movable arm (3) scanning means such as a georadar screen (5) is provided, which transmits radar waves having a suitable wavelength and scans the ground area in front of the vehicle (1). The georadar determines the depth of soil and obstacles to planting such as stones and stumps. From the determinations of the georadar also suitable planting places are determined and the positions thereof are stored. The planting arms (11) and their assemblies (13) are then controlled, so that during the continuous movement of the vehicle forwards the planting assemblies stand still at the determined planting places and there perform planting. Owing to the determination of the soil conditions planting can be made with a high yield and due to the automated procedure using a minimum of man power.

Title: Method for making plywood
Inventor: CAMPY AARO JOHN
IPC: B27D1/04
Filed: 1999-10-29
Abstract: A method for making hardwood or decorative plywood. The plywood includes a number plies including a back veneer, a face veneer, and a number of core and center plies. The method forms subunits of plies and stacks the discrete formed subunits to form a unit. The unit is processed to forms discrete hardwood panels. Subunits having different sets of plies are formed. The subunits are formed by sequencing the order of placement of the plies so that the face and back veneers do not touch the conveyor. This process enables line assembly of hardwood plywood. Without this sequencing, at least the back veneers would touch the conveyor subjecting the panel to aesthetic damage due to the nature of the outer veneers. This process also significantly reduced the labor necessary for forming the panels because numerous subunits can be formed simultaneously.

Title: Fiber-optic frequency shifter, optical interferometer and method of generating two complementary optical interference signals using the same
Inventor: KIM BYOUNG YOON
IPC: G02B6/34
Filed: 1999-03-30
Abstract: This invention relates to optical devices such as a fiber-optic frequency shifter and an optical interferometer. This invention also relates to a method of generating optical interference signals to obtain reliable sensor signals independent of polarization fluctuations of the optical waves in the fiber. Fiber-optic interferometers have many advantages such as high sensitivity and convenient way of using even in poor surrounding environments. These interferometer, however, exhibit polarization dependent signal degradation since the polarization of a light wave passing through an optical fiber irregularly changes depending on the birefringence of the fiber. This invention is characterized in that the frequencies of two orthogonal eigen polarizations of a light wave are shifted to different frequency values at one optical path of the interferometer. They produce two beat interference signals after interfering with the light wave passed through the other optical paht of the interferometer. The two beat interference signals have amplitudes varying complementarily. Selecting the larger one from the two beat signals can prevent polarization dependent signal degradation. Moreover, the beat signals from the optical interferometer according to the invention requires simpler signal processing compared to the output of conventional fiber-optic interferometer.

Patent CA-2300661-A1 (CA)
Inventor: WILKINSON SCOTT L
IPC: H04B7/15
Filed: 2000-03-14
Abstract: A method employing a demand assigned multiple access protocol for transmitting data on a processing satellite uplink and downlink in a satellite communications network, where multiple users are assigned to a common data transmission resource as part of a sharing set. A DAMA processor (32) on the satellite maintains a reservation log which identifies the uplink time slots in a non-contentious main flow resource that are currently reserved by the members of the sharing set, and allows the members of the sharing set to reserve the available time slots. To reserve a time slot on the main flow resource for the non-contentious transmission of data, a user of the sharing set will transmit a reservation request to the satellite on a contentious control flow resource (14). If a return message is not received (18), the user knows that the reservation request collided with another reservation request, and a retransmission strategy is employed (20). When the DAMA processor (32) receives the reservation request, it decides whether to grant, deny or delay the request based on predetermined criteria, including whether the requesting user already has a reservation (36), the length of the reservation request (40), the congestion state of the destination downlink port, and other flow control parameters. The DAMA processor (32) will issue a reservation grant message to the requesting user that includes the time, frequency and length to send the data on the main flow. When the requesting user receives the reservation grant message (16), it will then wait for its reserved time slot (22) to transmit the data on the main flow resource (24).
