  • Patent number: 9653863
    Abstract: When a hobby enthusiast has recharged the battery for a remote controlled vehicle, such as a scale facsimile automobile, boat, helicopter or airplane, the battery must be connected again to the vehicle drive system, to provide power. This operation is typically performed by connecting each lead of an electronic speed controller to each corresponding lead of the battery, through a removable barrel receptacle lead and a mating barrel plug lead respectively, attached to each corresponding lead. An improved connector lead is described herein that protects components that may be attached to either lead in a connection. The charge dissipates in a resistive member that is physically coupled to a conductive member to form at least in part a first lead.

  • Patent number: 9625903
    Abstract: Electronic components that are operable within remote control vehicles include Electronic Speed Controllers, radio control receivers, and telemetry transmitters. Hardware and software are described that support communication between a user computer and electronic components. A data link device has analog input and output interfaces that communicate to a mobile computing device such as smartphone. The data link device communicates with an electronic component to send and receive data such as parameters or operational data over a wired bidirectional bus interface. Software for performing data link operations run for example on an electronic component, a mobile computing device, a smartphone, a data link device, or a telemetry receive radio, or a combination of the above.

  • Patent number: 9166506
    Abstract: Control of rotational speed of a motor is provided using an apparatus and method that provides a staging and a driving mode. A processor controls speed of the motor in three different modes to provide different control that is appropriate for different situations. Control-input indications are received by a processor indicating that a stepping mode is selected. In stepping mode, a sequence of commutation states are chosen in succession at a given stepping frequency for a given control selection. In an active-holding mode, the same phase in the commutation sequence is pulsed at low power to hold a motor location. In a closed-loop motor-control mode, the commutation state is sensed and state transition time is controlled relative to neutral timing. These modes may be used to advantage to simulate a drag race. An operator controls a remote-control vehicle in a stepping mode to drive toward a first beam at a drag start line.

  • Patent number: 8049601
    Abstract: Systems and methods are provided for controlling one or more servos coupled to a model vehicle. An input signal having a series of input pulses encoded at an input pulse repetition frequency is received at a receiver coupled to a model vehicle having one or more servos. The input signal is decoded at the receiver. A servo control pulse is generated using at least one of the input pulses at the receiver. The servo control pulse is outputted to at least one of the servos at an output pulse repetition frequency that is different from the input pulse repetition frequency.

  • Patent number: 7831351
    Abstract: Systems and methods are provided for processing control inputs at a receiver for one or more servos coupled to a vehicle. A signal containing a plurality of control inputs generated in response to an activation of at least one control element on a transmitter is received at a receiver mounted on a vehicle. The plurality of control inputs is mapped to a vehicle-specific set of servo control signals at the receiver using operations such as reversing, shifting, scaling, delaying, and mixing.

  • Patent number: 7624566
    Abstract: A Hall effect plasma accelerator includes inner and outer electromagnets, circumferentially surrounding the inner electromagnet along a thruster centerline axis and separated therefrom, inner and outer magnetic conductors, in physical connection with their respective inner and outer electromagnets, with the inner magnetic conductor having a mostly circular shape and the outer magnetic conductor having a mostly annular shape, a discharge chamber, located between the inner and outer magnetic conductors, a magnetically conducting back plate, in magnetic contact with the inner and outer magnetic conductors, and a combined anode electrode/gaseous propellant distributor, located at a bottom portion of the discharge chamber. The inner and outer electromagnets, the inner and outer magnetic conductors and the magnetically conducting back plate form a magnetic circuit that produces a magnetic field that is largely axial and radially symmetric with respect to the thruster centerline.

  • Patent number: 7582081
    Abstract: Systems, methods and apparatus for performing selective ablation of a corneal surface of an eye to effect a desired corneal shape, particularly for correcting a hyperopic/astigmatic condition by laser sculpting the corneal surface to increase its curvature. In one aspect of the invention, a method includes the steps of directing a laser beam onto a corneal surface of an eye, and changing the corneal surface from an initial curvature having hyperopic and astigmatic optical properties to a subsequent curvature having correctively improved optical properties. Thus, the curvature of the anterior corneal surface is increased to correct hyperopia, while cylindrical volumetric sculpting of the corneal tissue is performed to correct the astigmatism. The hyperopic and astigmatic corrections are preferably performed by establishing an optical correction zone on the anterior corneal surface of the eye, and directing a laser beam through a variable aperture element designed to produce a rectangular ablation (i.e.

  • Patent number: 7579796
    Abstract: Control of rotational speed of a direct current multi-phase brushless motor is provided using an apparatus and method that works at low speed but does not depend upon Hall effect sensors. An apparatus for accelerating rotation of the motor shaft has a power stage circuit coupled to a back Electromotive Force (EMF) sensor circuit and a microprocessor. The power stage pulses at a duty cycle less than 100% under control of the microprocessor. The back EMF sensor circuit measures an order with respect to voltage of at least one phase relative to one or more other phases during off-time. The microprocessor determines one or more phases to be pulsed, and the polarity of the pulses based on the measured order. A method for sustaining rotation pulses the phases, measures order with respect to voltage of at least one phase relative to one or more other phases, and updates commutation state based on the measured order.
