An anti lock braking system for commercial vehicles is described. The system includes a rear axle brake assembly having a rear brake for each rear wheel, a relay valve for controlling rear axle brakes and a plurality of pressure modulator valves operatively connected to the relay valve, each having an outlet connected to one of the rear brakes. Multiple connector cartridges are used to sealingly connect the relay valve to each of the pressure modulator valves. The connector cartridges have a first end defining a non rotation-dependent fitting, such as a cartridge fitting, cooperating with a corresponding port cavity to form the sealed connection.

A wheel speed sensor assembly includes a sensor having a housing configured to be received within a bore in a mounting block such that the sensor is spaced from, and faces, an exciter ring and senses rotation of the exciter ring. The housing extends along a longitudinal axis and defines a key on a radially outer surface having first and second portions having different heights. The first portion is configured to be received within a first keyway that is formed in the mounting block and is in communication with the bore in the mounting block. A clamping sleeve is configured to secure the sensor within the bore in the mounting block. The clamping sleeve defines a bore configured to receive the housing of the sensor and a second keyway in communication with the bore in the clamping sleeve. The second portion of the key is received within the second keyway.

A valve includes at least one of an electrical port adapted to receive an electronic control signal and a pneumatic control port adapted to receive a pneumatic control signal. The valve also includes a pneumatic delivery port. The pneumatic delivery port is adapted to transmit a pneumatic fluid, based on the at least one of the received electronic control signal and the received pneumatic control signal, from a second independent source to control i) a second associated service brake and ii) delivery of the pneumatic fluid from a first independent source to control a first associated service brake.

A method of operating an acceleration system comprises injecting charged particles into an RF accelerator, providing RF power to the accelerator, and accelerating the injected charged particles. The accelerated charged particles may impact a target to generate radiation. The RF power is based, at least in part, on past performance of the system, to compensate, at least partially, for dose and/or energy instability. A controller may provide a compensated control voltage (“CCV”) to an electric power source based on the past performance, to provide compensated electric power to the RF source. A decreasing CCV, such as an exponentially decreasing CCV, may be provided to the electric power source during beam on time periods. The CCV to be provided may be increased, such as exponentially increased toward a maximum value, during beam off time periods. The controller may be configured by a compensation circuit and/or software. Systems are also described.
