  • Publication number: 20210349067
    Abstract: A sensor system is disclosed that includes a plurality of sensors, a deployment system for deploying the sensors, a control and charging system for receiving sensor data and optionally charging the batteries within the sensors, and one or more algorithms employed by the sensor system for processing, analyzing, and otherwise using data received by the plurality of sensors.

  • Patent number: 8490758
    Abstract: An electro-hydraulic brake system for a vehicle can include at least one hydraulic piston that exerts a force on a brake pad in a direction away from a brake disk and opposite to a force exerted, e.g., by a spring, on the brake pad in a direction toward the disk. A hydraulic pressure actuator can in one embodiment actuate the hydraulic piston to hold the brake in a disengaged position. A controller can in one embodiment actuate the hydraulic pressure actuator to advance the brake pad into engagement with the disk to exert a braking force based on a brake command signal, and can in one embodiment actuate the hydraulic pressure actuator to retract the brake pad from engagement with the disk upon receipt of a brake release signal. In one embodiment, the brake pad can move into engagement with the brake disk when an emergency (e.g., a loss of power or hydraulic pressure) occurs.

  • Patent number: 8104589
    Abstract: An electro-hydraulic brake actuator for a vehicle can include an electric motor configured to operate at about 28 Vdc, and to operate at about 2 Amps or less to hold a vehicle brake in a disengaged position. A hydraulic master piston can be operatively coupled to the electric motor, the hydraulic master piston configured to slidingly move within a master cylinder fillable with a hydraulic fluid such that advancement of the master piston within the master cylinder varies the hydraulic pressure supplied to the vehicle brake. The electric motor and hydraulic master cylinder are configured to fit within a wheel hub corresponding to the vehicle brake, the motor configured to operate the hydraulic master piston to vary the hydraulic pressure applied to the brake.
