Abstract:
When starting a screw-type air compressor (12) in sub-zero conditions, current spikes are mitigated by detecting an over-current condition and/or a below- threshold temperature, and a warm-up routine (28) is initiated in which compressor motor (22) speed is ramped in a sawtooth fashion between two speeds that are substantially lower than a nominal operating speed of the compressor motor (22). In this manner, the internal components of the compressor (12) are warmed prior to fully starting the compressor (12), which mitigates current spikes, reduces blown fuses, and extends the life of the compressor motor (22) and other compressor components.
Abstract:
Disclosed are various systems and methods for processing and displaying video in a vehicle. In one embodiment, a vehicle video system (101) is provided that comprises a plurality of cameras (103, 106) mounted in a vehicle (100), each of the cameras generating a video image, and the cameras including a plurality of visible light cameras (103) and a plurality of night vision cameras (106). The vehicle video system (101) also includes a video processing unit (109), where each of the cameras and each of the monitors (113) are electrically coupled to the video processing unit (109). The video processing unit (109) being configured to select at least two subsets of the cameras from which output video images are obtained for display on monitors (113).

Abstract:
A backward movement indicator apparatus is provided for a vehicle having an alert device. The backward movement indicator apparatus comprises an image capture device arranged to capture image data which is representative of objects in vicinity of the vehicle. The backward movement apparatus further comprises an electronic controller arranged to process the captured image data to provide a signal which is indicative of the vehicle moving backwards.
Abstract:
Se proporciona un aparato indicador del movimiento de reversa para un vehículo que tenga un dispositivo de alerta. El aparato indicador del movimiento de reversa comprende un dispositivo de captura de imagen ordenado para capturar datos de imagen representativos de objetos en las cercanías del vehículo. El aparato indicador del movimiento de reversa además comprende una unidad de control electrónico acomodada para procesar los datos de la imagen capturada para proporcionar una señal que indique que el vehículo se mueve hacia atrás.

Abstract:
The vision system controller selects a video signal to be displayed on a display device, from several video signals received from corresponding cameras. A screen overlay controller overlays a message on the selected video signal and displays on the display device. An independent claim is also included for vision system interface method.
Abstract:
A vision system interface and method are provided for use in a commerci al vehicle. In one embodiment, the vision system interface comprises at least o ne input through which at least one of a plurality of video signals is received from a corresponding plurality of cameras for display on a display device. The visi on system interface also comprises a vision system controller facilitating a selection of at least one of the video signals that is to be displayed on the display device, the vision system controller being adapted to generate at least one message to be displayed on the display device. The vision system interface further compris es a screen overlay controller adapted to overlay the at least one message onto t he at least one selected one of the video signals for display on the display devic e.
Abstract:
A system and method for detecting alternator condition is provided. Information is taken from the vehicle powerline and the communication links, and processed by the vehicle ECU, such as the vehicle antilocking brake system ECU, to obtain data. The battery voltage ripple amplitude is then calculated and compared at different engine speeds. If the difference in the ripple amplitude at the different engine speeds is greater than a predetermined threshold value, a signal is sent indicating that the alternator has failed.
