Abstract: In a method and a corresponding device for determining the optimal altitude for altitude control for a vehicle (1), flying at a low altitude over a sea surface, like an anti-ship missile, the distance between the sea surface and the vehicle is measured by an altimeter (2), placed in the vehicle. The altimeter gives an altitude signal, corresponding to this distance, which is varying due to the wave structure of the sea surface. The al­titude signal is processed in a signal processing unit (3), which gives to the steering means (4) of the vehicle (1) an altitude control signal, which is dependent on the difference between the actual altitude of the vehicle and the optimal altitude (H o ). The altitude signal is filtered in the signal processing unit (3) to eliminate any superimposed signals, the frequencies of which lie outside of a predetermined range of frequencies, comprising the range of frequencies of the wave movement. The rms-value of the filtered altitude signal is determined in the signal processing unit (3). An acceptable risk of a wave hit for the vehicle (1) is established. The optimal altitude (H o ) is calculated, considering the rms-value determined and the established risk of a wave hit for the vehicle (1).

Abstract: A glycoprotein phosphotyrosyl protein phosphatase is isolated from human tissues, such as human placental membrane. Upon membrane solubiliz­ation and extraction of the enzyme it was subjected to chromatographic purification and isolation. The analytical and biological responses of the enzyme demonstrate that it is novel and readily distinguished from other enzymes previously isolated from similar tissues. The enzyme is a dephosphorylation enzyme of membrane phosphoprotein kinases, and as such has utility as an antidiabetic agent, an antiatheroscler­osis agent or an antitumor agent since certain membrane receptor kinases involved in each such biological function involve a phosphorylation mechanism for cell transformation, metabolism and growth and which, when blocked by the instant enzyme, results in a suppression or alteration of the biological function.

Abstract: An orthodontic finishing positioner (20) for maloccluded teeth (T) to which are secured coupling members (21) having portions protruding from the sides of the teeth includes a body (22) constructed of an elastomer base material comprised of a silicone elastomer composition adapted to be operatively positioned about the teeth and coupling member of at least one dental arch of a patient. The positioner body is arcuate in shape and defines a recess (24,26) for receiving teeth of at least one dental arch wherein the recess includes walls (43) defining teeth-engaging surfaces (44) shaped generally complementary to the surfaces of the teeth (T) of the one dental arch when the teeth therein are positioned in a predetermined or ideal orientation. The recess walls (43) further defines a series of indentations (46) disposed across the teeth-engaging surfaces (44) wherein each indentation (46) is shaped to nestingly accept a corresponding coupling member (21) so that when the positioner body is operatively positioned within the patient's mouth and stretched about the teeth of the one dental arch so that the teeth thereof are operatively received by the recess of the arcuate-shaped portion and each coupling member is accepted by a corresponding indentation, the stretched body effectively grasps the teeth and acts against the teeth and the coupling member to bias the teeth of the one arch toward the predetermined orientation. The elastomer composition of the positioner body, when in an uncured condition, possesses a sufficiently low viscosity so that the positioner (20) can be formed in a low pressure injection molding process and which, when in a cured condition, possesses a relatively high resistance to tear. The method of the invention includes the steps involved in constructing the positioner of the invention. Such construction steps include the constructing of an impression-formed model (82) of the teeth and coupling member (21) of the one dental arch, repositioning the teeth-simulating portions of the model to a predetermined orientation and utilizing the model, with its repositioned teeth-simulating portions, as a standard for the formation of the desired positioner.

Abstract: The method of the present invention improves the damping property of the yaw motion of the vehicle by feeding back a detected yaw rate value (r) in a dynamic sense for compensating the front wheel steer angle (8f) so as to increase the damping coefficient(Ç) of the yaw motion of the vehicle. By controlling the front wheel steer angle by accounting for not only the proportional term of the steering wheel input angle (8sw) but also the derivative term which is proportional to the steering wheel input angular speed, in the feed-forward control of the front wheel steer angle in relation with the steering operation by the driver, and by appropriately varying the control parameters of the yaw rate feed-back and the steering wheel input feed-forward, the yaw response of the vehicle can be made proportional to the steering wheel input, and the response delay in the yaw rate against the steering wheel input can be reduced to substantially zero.
