摘要： A control device for digital display indicators using electromagnetic drums.An analogue/digital converter converts the information to be displayed, received in analogue form E, into digital information which can be utilized by the drums of the display device. The renewal frequency of the information delivered by the analogue/digital converter is made a function of the rate of change of the information by means of a differentiator which calculates the derivative dE/dt and a means of comparing voltages and/or frequencies and means of controlling the analogue/digital converter and/or all or a proportion of the display drums.

摘要： A digital indicator system in which a command signal activates a switching network selectively to couple digitally generated, bipolar, phase-displaced signals to the two-phase internal stator windings of a stepper motor having an outer permanent magnet rotor to cause the rotor always to step in the same direction no matter at what time the switching network is activated by the command signal. The rotor locks magnetically onto the stator poles of one phase when the input to the motor disappears. Miniature code drums driven by the stepper motor rotors provide feedback signals which are compared with the command signal to deactivate the switching network when the rotors reach the commanded positions.

摘要： A self-rotating display device includes and outer light transmissive container (402) containing a light transmissive fluid (406) and an body (404) containing an electric motor (421) for rotating the body with respect to the outer container. The body also carries an amount of the fluid (430a) contacting the fluid in the outer container through a pressure equalizing gap (431) in the body which forms a fluid pathway between the inner cavity of the body and the inner chamber of the outer container. The fluid pathway forms self-regulating pressure relief structure which accommodates slight pressure variations in the fluid due to climactic conditions for example. A specialized reduced footprint fluid-immersible electric motor having separate field and compass magnets, which do not rotate relative to each other, helps eliminate magnetic cogging. The device can be manufactured according to a method which eliminates the necessity of a fill hole in the body.

摘要： In a multi-polar electromagnetically energized rotary indicator each of the pole pieces is associated with a significantly isolated flux path, which, at one end of the turning axis of the rotor part of the indicator, leads diametrically to a flux concentrator displaced 180.degree. from the pole piece in question. In a particular embodiment, this result is realized by a system of separate but mutually nested bridging parts of ferromagnetic material, each of which defines an essentially independent flux path. Other embodiments provide quasi-independent flux paths serving a similar electromagnetic function. An arrangement for sensing the response of an indicator is described.

摘要： A method for adaptive wind-driven outdoor all-surrounding information display is disclosed, the method including: 1) installing an outdoor information display apparatus, of which a support means cooperates with a wind rotating means to achieve wind power generation and rotational speed control of an information display means; 2) disposing a plurality of electronically controlled light-emitting display strips on the sails; 3) installing a plurality of working units of a motor/electric generation assembly; 4) installing a control system so that the dynamic trajectories of the rotating electronically controlled light-emitting display strips after they are lit are successively connected with each other thereby creating an all-surrounding and continuous visible graphic and textual image. Apparatuses and control systems implementing the above method are also provided.
