A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.

Systems and methods for illumination control and distribution during a vehicle bank

A light assembly and method for steering a vehicle headlight illumination pattern. In one aspect, a method includes providing a processor programmed to perform the steps of: illuminating a subset of consecutive LEDs in the line including LEDs associated with the first and second edge illumination fields; as the direction of the vehicle wheels changes: (i) fading the LED associated with one of the first and second illumination fields off while simultaneously fading the LED associated with the other of the first and second illumination fields on thereby changing the illumination pattern; and (ii) repeating step (i) so that the illumination pattern tracks the direction of the vehicle wheels.

Induction heating power supplies, data collection systems, and induction heating systems to communicate over an induction heating cable are disclosed. An example induction heating power supply includes a power conversion circuit configured to: convert input power into induction heating power and transmit the induction heating power via an induction heating cable, and at least one of a receiver circuit coupled to the induction heating cable and configured to receive data via the induction heating cable or a transmitter circuit coupled to the induction heating cable and configured to transmit data via the induction heating cable.

A heating system includes a power source connected to a heater to heat a workpiece via the heater and a controller. The controller is configured to receive the first temperature measurement signal, the first temperature measurement signal corresponding to a first temperature of the workpiece. The controller is to turn on the power source to activate the heater to heat the workpiece, receive the second temperature measurement signal in response to heating the workpiece, the second temperature measurement signal corresponding to a second temperature of the workpiece. The controller calculates a change in temperature of the workpiece based on the first and second temperatures, and determines a physical characteristic of the workpiece based on the change in temperature.

Systems and methods to determine workpiece characteristics

Induction heating accessories are disclosed. An example induction heating accessory comprises: a coupling circuit configured to be electromagnetically coupled to a cable carrying induction heating current; a power extraction circuit configured to extract power from the induction heating current via the coupling circuit; and circuitry configured to generate an output indicative of the induction heating current flowing through the cable based on receiving power via the induction coil.

A light assembly for generating a light pattern comprising LEDs; a first lens positioned in front of the LEDs to direct light from each LED into an illumination field, the illumination fields of energized LEDs create an illumination pattern and a first edge illumination field and a second edge illumination field; a processor controlling the LED duty cycles to move the illumination pattern in a first direction to the side of the first edge illumination field by (i) increasing an LED duty cycle associated with the first edge illumination field while decreasing an LED duty cycle associated with the second edge illumination field; and (ii) repeating step (i) with the illumination field adjacent the first edge illumination field in the first direction as the first edge illumination field and with the illumination field adjacent the second edge illumination field in the first direction as the second edge illumination field.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank. In some embodiments, the vehicle illumination optics can include a primary illumination group and a plurality of side illumination groups.
