  • Publication number: 20180154874
    Abstract: The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

  • Publication number: 20170368897
    Abstract: The present disclosure includes a system, method, and device related to data collection and communication related to after-market and external vehicle systems, such as towing systems, cargo carrying systems, trailer breakaway systems, brake systems, braking control systems, and the like. Data is sensed, processed, shared, and further leveraged throughout the discrete components of the system, and possibly via internet and other communications' links, to effect various beneficial actions with minimal driver/user interaction or intervention. In the same manner, data from the system may be used for diagnostic reasons, safety controls, and other purposes.

  • Patent number: 9758089
    Abstract: A trailer signal converter includes a plurality of inputs, including a first towing vehicle turn light signal, a second towing vehicle turn light signal, and a trailer brake signal. The trailer brake signal is a pulse-width modulated signal. The trailer signal converter selectively drives the turn and stop light signals on the trailer based on the input signals. In a three-wire system, the signal converter is configured to receive a brake signal input and a brake light input and selectively drive the trailer stop light signals.

  • Patent number: 6615125
    Abstract: A brake control unit for providing a brake output signal to a brake load includes a processor, an accelerometer and a memory subsystem. The accelerometer is coupled to the processor and provides a brake control signal to the processor, which is configured to provide the brake output signal to the brake load in response to the brake control signal. The memory subsystem is coupled to the processor and stores processor executable code, which causes the processor to automatically set at least one of a gain level and a boost level for the brake control unit.

  • Patent number: 6445993
    Abstract: A brake control unit for providing a brake output signal to a brake load includes a processor, an accelerometer and a memory subsystem. The accelerometer is coupled to the processor and provides a brake control signal to the processor, which is configured to provide the brake output signal to the brake load in response to the brake control signal. The memory subsystem is coupled to the processor and stores processor executable code, which causes the processor to automatically acquire an operating point of the brake control signal when the brake control unit is mounted within a range of operating positions.

  • Patent number: 5133346
    Abstract: An apnea monitoring system which utilizes a portable data storage cartridge for storing the monitored events and waveforms of a patient's respiration, ECG and the like. The cartridge is easily carried or mailed to a remote location and connected to a transfer unit to provide a cost-effective and time-efficient method of transferring the stored information to a computer for displaying selected events and waveforms. The monitor includes provisions for indicating the available memory space on the cartridge, and the cartridge is replaceable to provide an unlimited amount of memory space and permit continued use of the monitor during transferring of information to a computer.
