专利汇可以提供Device for producing electrical signals by means of a control stick专利检索，专利查询，专利分析的服务。并且A device for producing electrical signals, comprises a control stick which is pivotally mounted for back and forward movement intermediate its length. One end of the control stick, for example the bottom end, is provided with a source of luminous radiation adjacent this end, and the stick is biased into a neutral position, for example a central position, by means of spring elements engaging it from respective opposite sides. The apparatus includes at least four fixed photosensitive cells which are disposed symmetrically about the radiation source. Two of each of the photosensitive cells are connected to each of two circuits of an electrical transmission means which comprises two electrical circuits. The source of radiation is advantageously surrounded by a screen which is secured to the control stick for movement therewith. Preferably, two photosensitive cells are disposed at mutually opposed locations and connected in a common circuit with the cells disposed in one plane and the cells disposed in the opposite plane being mounted in opposition to each other.，下面是Device for producing electrical signals by means of a control stick专利的具体信息内容。

权利要求

1. A device for producing signals, comprising a control stick having a manipulatable handle portion and being universally pivotally movable to transmit control signals, universal mounting means mounting said control stick for universal pivotal movement, biasing means urging said control stick into a neutral position, transmission means comprising two electrical circuits adapted to be influenced by the angular position of said control stick, a source of luminous radiation mounted on and adjacent an end of said control stick at a spaced location from its pivotal mounting, means associated with said luminous radiation source to shield the photocells from the source in predetermined positions of said control stick, and at least four fixed photosensitive cells arranged in opposed pairs disposed symmetrically about said radiation source and two being connected in each of said two circuits, the center lines of said cells each being in a plane containing the axis of said control stick in said neutral position and being disposed at an angle to each other which is less than 180*.

2. A device for producing signals, according to claim 1, wherein said shielding means comprises a screen surrounding said source of radiation and carried by said control stick and in which said photosensitive cells have bottom edges which extend in the same plane as the bottom edge of said screen.

3. A device for producing signals, according to claim 1, wherein said photosensitive cells are directly exposed to the said source of radiation.

4. A device for producing signals, according to claim 1, wherein said electrical circuits include a circuit having two photosensitive cells disposed at mutually opposed locations and being disposed in a plane which is perpendicular to the plane of the other two of said cells.

5. A device for producing signals, according to claim 1, wherein said photosensitive cells are passive cells.

6. A device for producing signals, according to claim 1, wherein said photosensitive cells are active cells.

7. A device for producing signals, according to claim 1, wherein said control stick is a double-armed lever, including an upper portion which is adapted to be engaged by a person''s hand and a lower portion on the opposite side of said pivotal mounting carrying said source of luminous radiation.

8. A device for producing signals, according to claim 7, wherein said source of luminous radiation is carried on the outer end of the bottom of said control stick.

9. A device for producing signals, according to claim 1, wherein said control stick comprises a single arm lever, said luminous source of radiation being spaced from said pivotal connection upwardly along said control stick.
