  • Patent number: 9126692
    Abstract: A remote actuation system for de-manning a human/machine interface emulates the interface protocol to interact with the interface at a mechanical level. The system may function autonomously or with a remote human operator. At least one imaging module and at least one switch module with the same relative positions as and a complementary relief to the interface's gauge(s) and mechanical switch(es) are mounted on the instrument panel. The modules may be individually mounted or provided on a remote actuation panel that fits over the instrument panel. A data cable connects the imaging and switch modules to a processing module having at least one computer processor configured to execute an image-processing sub-module and a switch sub-module to emulate the protocol to interact with the interface at a mechanical level. The estimate of the measured value may be fed back to generate the switch command to control the remote switch actuator.

  • Publication number: 20110142522
    Abstract: This invention proposes to use the typing force to generate electricity. Electromagnetic devices are placed under the keys of a keyboard. When a key is pressed, the electromagnetic devices are driven so that the magnets and the coils or the coils and cores have relative movement to generate the electricity. When the key is released, the force stored in the spring or between the magnets and the cores or both drives the key, the magnets, and the coils or the cores and coils back to their positions so that the magnets and the coils or the coils and cores have relative movement to generate the electricity. Any number of keys may share any number of electromagnetic devices. For the wireless keyboard, with the generation of the electrical currents when the typing keys are operated with pressing down or raising up movements, the batteries are no longer required and can be eliminated.

  • Patent number: 5911529
    Abstract: A keyboard power generator provides a plurality of keys with one or more magnets mounted thereon. Additionally, a plurality of coils are mounted on both ends of the magnet such that, when the user is typing, the magnet traverses the coils. The movement of the magnet over the coils causes a current to be generated. In one embodiment, one magnet is mounted per key on the keyboard. In a second embodiment, a plurality of magnets are mounted per key to enhance the power generation capability of the keyboard. The currents generated collectively by the keys are provided to a charge pump which multiplies the voltage to achieve a level greater than the voltage level of the battery to be charged. The multiplied voltage is provided to a charging circuitry such as a trickle charger to recharge the battery. In this manner, the more information entered by the user, the more electricity is generated by the keyboard power generator.

  • Patent number: 4469461
    Abstract: A low profile keyboard actuator for a typewriter in which L-shaped levers are pivotally mounted on a transverse shaft mounted immediately in front of the typewriter. The levers have generally horizontal arms of various lengths, the ends of which contact the keys of the various rows of the keyboard. The levers have depending arms of uniform length and are resiliently biased to depress the keys. A common operating bar bearing against the depending arms cyclically permits the levers to depress the keys and then restores the levers to the original position where no key is depressed; however, depression of all but a selected key is inhibited by a plurality of vertically superposed, transversely shiftable, binary-coded slides having teeth which bear against all depending arms except that one corresponding to the selected key.

  • Patent number: 4207010
    Abstract: An electric typewriter of the type having individual type elements for each character has attached thereto a system for controlling the actuation of the type elements and the control functions of the typewriter by digital signals. The digital signals may emanate from a remote central processing unit or other device. The control system is an attachment to the typewriter which does not interfere with the normal manual operation of the typewriter. The control system is mounted in a housing which is placed under the typewriter in predetermined alignment with the key lever actuation means and employs an electromagnetic actuator to set a condition for a mechanical actuator for each key lever. A mechanical actuator initiates a key stroke if the electromagnetic actuator is positioned in an ON position and does not initiate a key stroke if the electromagnetic actuator is in the OFF condition.

  • Patent number: 4146336
    Abstract: Actuators are positioned over the rows of keys in a keyboard to drive the keys in response to coded information from a computer or other source of digital signals. The mechanical driving force is transferred from solenoids positioned at one end of each row simultaneously to all of the actuators of that row. Additional solenoids positioned across the bottom of the keyboard sequentially unlatch selected actuators allowing them to drive their associated keys in response to the driving force. Additional solenoids are used to drive the shift mechanism and, if necessary, other individual keys.
