  • Publication number: 20240074365
    Abstract: There is provided maintaining, at a network service operatively connected to a logging machine, master forest resource information, wherein the master forest resource information comprises prediction cells for product yield over a work area or a set of work areas, receiving, at the network service from the logging machine, logging machine measurements associated with the work area or the set of work areas, associating, at the network service, the received logging machine measurements to at least one prediction cell of the master forest resource information, determining, at the network service, based on the received logging machine measurements, a logging machine product yield for the work area or the set of work areas, modeling, at the network service, a difference between the logging machine product yield and a product yield of the at least one prediction cell, and compensating, at the network service, product yields of prediction cells based on the modeled difference.

  • Patent number: 5779115
    Abstract: A carrying device which is used together with a mobile station and with which the mobile station can be attached to a target and detached from the place of attachment and re-attached to it. The attachment device comprises a support stud (2) attached to a mobile station (10) and a carrying device (1) attached to a target by way of an attachment element (5), including gripping elements for a detachable grip on the support stud. The gripping elements of the carrying device comprise guide grooves (8) for the reception of the support stud (2) and a tongue (7) moving transversely (6) against the plane (4) of the guide grooves and held by a spring (13) in a locking position (L) extending across the plane of the guide grooves. The carrying device has a hand-operated slide (27) which includes an element (12) to force the tongue against a spring force (F) off the position extending across the plane of the guide grooves, thereby moving it into a release position (R) which releases the support stud.

  • Patent number: 5423070
    Abstract: In a method according to the invention the tuning information determined by a measuring computer (20) is stored in the memory of the radio telephone (1). In operation the microprocessor (10) receives from the sensors (14) information e.g. about the temperature, according to which it selects from its memory tuning data and adjusts signal levels and deviations through logic controlled amplifiers (16, 17). The tuning can be made automatically, without opening the casing of the radio telephone.

  • Patent number: 5335362
    Abstract: In the method of tuning the received signal strength indicator the tuning results for selected operating conditions are stored in the microprocessor (10) memory. When the radio telephone (1) is in use, the received signal strength indicator (RSSI) reading is corrected with the tuning result in order to select the strongest antenna signal. The tuning is performed by connecting the tuning equipment (2)to the external interfaces (31, 32) of the radio telephone without opening it.

  • Patent number: 5313656
    Abstract: Radio telephone tuning information is determined by a measuring computer (20) stored in the memory of the radio telephone (1). A microprocessor (10) receives from the sensors (14) information about the operating temperature, according to which appropriate tuning data is selected from memory. The information is used to adjust signal levels and deviations through logic controlled amplifiers (16, 17). The tuning can be made automatically without opening the casing of the radio telephone.

  • Patent number: 5077783
    Abstract: In accordance with the invention a radio telephone (1) is tuned so that the tuning equipment (2) selects the signal (S1, S2) to be tuned via the microprocessor (10) and the multiplexer (13), and that the logic controlled amplifiers (11, 11') are controlled to obtain the desired tuning result. The set values corresponding to the tuning result are stored in the microprocessor memory. When the radio telephone is in operation, the signals are amplified in accordance to the set values. The tuning can be performed without opening the radio telephone.
