Abstract: A sensorless induction motor control device with a function of correcting a slip frequency wherein a slip frequency estimation unit estimates the slip frequency from at least one kind of current flowing through the motor. A voltage command value calculation unit calculates a D-phase voltage command value and a Q-phase voltage command value which are used for controlling a voltage applied to the motor using a Q-phase current command value calculated based on a difference between a speed estimation value, which is calculated using an estimation value of the slip frequency, and an externally supplied speed command value. An ideal voltage command value determination unit determines an ideal voltage command value using the speed command value and the Q-phase current command value. An actual voltage command value calculation unit calculates an actual voltage command value using the D-phase voltage command value and the Q-phase voltage command value.

Abstract: The present invention relates to a transmission method for a transmitter having Nt transmit antennas. The method (1) spreads symbols in two dimensions by means of a spreading code, the symbols coming from a signal for transmission over Nfft sub-carriers via the Nt transmit antennas. The signal is transmitted with a power pem(k) that is determined per symbol m, per user k=1, . . . , Nu, and per transmit antenna. The principle of the method (1) is to determine (2) a set of powers pem(k) that is constant over a symbol frame, with the distribution of power amongst the users minimizing an overall error criterion under the constraint that the sum of the powers pem(k) in the set is equal to the product of the number of users multiplied by the average power emitted per symbol over the users.

Abstract: A method and system of deterring mammals is disclosed involving incurring an acoustic startle response comprising the steps of selecting a target order, family, genus or species to be deterred, selecting a received level that is a predetermined level above a representative hearing threshold of the targeted mammals, and, taking transmission loss into account, transmitting an acoustic signal at a source level required to create the selected received level at a predetermined distance from the transmission point. The acoustic signal may comprise frequency components at which the aural sensitivity of the targeted mammals is greater than that of selected other animals, preventing the disturbance of the selected other animals while deterring the targeted mammals. In addition, a secondary conditioning sound may be played prior to the main acoustic signal to condition the mammals to avoid the main stimulus.

Abstract: Force-controlled autodistraction for lengthening a bone is disclosed. A distractor is coupled to first and second fixators that are coupled to first and second portions of the bone, respectively, on opposite sides of an osteotomy of the bone. A motor produces a motion of the first fixator relative to the second fixator such that the first portion of the bone is distracted from the second portion of the bone. A force sensor measures a resistant force to the motion, and a distractor displacement sensor measures a distractor displacement. A controller is operably coupled to the force sensor, the distractor displacement sensor, and the motor. The controller is configured to determine a variable limb stiffness using the resistant force, the distractor displacement, and a known distractor stiffness of the distractor, and to adjust a gain of the motor such that the variable limb stiffness matches a desired limb stiffness.
