A method for monitoring a wheel system by comparing a wheel end temperature to a wheel end temperature threshold; generating a brake monitoring signal when at least one brake monitoring condition has occurred; and generating a wheel monitoring signal if a brake monitoring signal is generated when the wheel end temperature is greater than the wheel end temperature threshold. The brake monitoring conditions may include (i) a brake supply pressure is less than a brake supply pressure threshold; (ii) a brake control pressure is greater than a first brake control pressure threshold and a stop lamp power signal is not present; and/or (iii) the stop lamp power signal is present and the brake control pressure is not greater than a second brake control pressure threshold. A brake monitoring system configured to monitor a wheel system.

Brake monitoring system with temperature monitoring

An anti-lock brake system module for a trailer or dolly, including a module panel having a front side and a back side facing in an opposite direction to the front side, a plurality of anti-lock brake system components, at least a portion of the components attached to the front side of the module panel and at least a portion of the components attached to the back side of the module panel, the plurality of anti-lock brake system components including an anti-lock brake valve and an electronic control unit, and a mounting element for removably connecting the module panel to a mounting location, such as an I-beam, of the trailer or dolly.

Brake system module removably attachable to a vehicle

A vehicle monitoring system for monitoring pressures on the service and emergency brakes, tires and suspension of a tractor trailer. The system also monitors electrical stoplight power to the ABS brakes as well as various additional vehicle systems listed within the claims. The monitoring system also provides visual and audible alarms to the operator as well as an additional output to signal a wireless device to warn the operator's employer if the warning is ignored.

Vehicle monitoring system with multiple inputs for a tractor-trailer

An apparatus and method for mounting a trailer/dolly air brake system module onto a mounting surface of a trailer/dolly using a mounting element. More particularly, a trailer/dolly air brake system module is mounted to an I-beam or C-channel of the trailer/dolly via welding methods, fasteners, or clamps. This allows the trailer/dolly air brake system module to be easily removable and replaceable, minimizing trailer/dolly down time as well as diagnostic troubleshooting/repair time. More particularly, the system module is for a trailer/dolly air brake system module. The method allows for continued use of a trailer/dolly vehicle.

Method and apparatus for mounting a system module to a vehicle

An air brake monitoring system for monitoring a pressure of the system and providing various alarms and/or warnings to a user including tire and brake status/alarms and providing for a backup alarm. The air brake monitoring system configurable to function with the existing wiring of the vehicle and including an air brake monitoring device to be positioned in the vicinity of a brake valve. The air brake monitoring system is further provided to monitor the electrical stoplight power transmitted to the ABS brakes as well as the vehicle static/dynamic condition.

Trailer/dolly ABS system module

An air brake monitoring system for monitoring a pressure of the system and providing various alarms and/or warnings to a user. The air brake monitoring system configurable to function with the existing wiring of the vehicle and including an air brake monitoring device to be positioned in the vicinity of a brake valve. The air brake monitoring system is further provided to monitor the electrical stoplight power transmitted to the ABS brakes as well as the vehicle static/dynamic condition.

Brake monitoring system

A control circuit for a sump pump or other pump that controls the liquid level in a vessel. The liquid is maintained between upper and lower levels defined by probes in the vessel. The probes are associated with comparators and connect with one comparator input. The upper limit comparator connects with the gate of an SCR which supplies current to the lower limit comparator and also to a relay which controls the on/off condition of the pump. The output of the lower limit comparator controls a switching transistor which is arranged in a series circuit with the SCR and relay coil. Once the SCR is conductive, it is latched in the conductive state until the transistor is made nonconductive by the lower limit comparator. In a sump pump application, latching of the SCR allows the pump to remain activated after the liquid level is reduced below the upper probe.

Water level control circuit for sump pumps and the like

A sump pump powered by a rechargeable battery has a circuit for monitoring the battery voltage and controlling charging of the battery. Four comparators monitor the battery and control two flip flops one of which operates the pump in cooperation with a float switch and the other of which turns the battery charging circuit on and off. The circuit is arranged so that when the battery is in its discharge cycle, the float switch controls the pump and the charging circuit comes on only when the battery voltage is in a low range. In the charging cycle, the pump is locked out in a low voltage range of the battery and is controlled by the float switch only in a high voltage range.
