Abstract:
A transport refrigeration system (100) includes an engine (102), a primary power source (104) driven by the engine (102) and a secondary power source (106) driven by a vehicle component (108) upon vehicle braking. An energy storage unit (110) stores energy from the secondary power source (106). A power control unit (112) is coupled to the primary power source (104) and the energy storage unit (110). A controller (114) is coupled to the power control unit (112) and a refrigeration component (116, 118) is coupled to the power control unit (112). The controller (114) operates the power control unit (112) to distribute power to the refrigeration component (116, 118).
Abstract:
A tractor cab has an access door with an associated door latch to hold the door in a shut position and an openable panel such as a window which is secured in a closed position by a window latch mechanism which acts between the window and cab. The window latch mechanism includes resilient means which, when the window is secured in its closed position, allows the window to move outwardly relative to the cab when the door is slammed shut thus ensuring that the door latch can be engaged.

Abstract:
The present invention relates to a vehicle sleep safety device comprising: a switch for connecting an oxygen sensor provided in an indoor area with a battery, which is a power source unit even when a vehicle start switch is turned off, or outputting an electrical signal by linking the same with an operation of the vehicle start switch or a switch with respect to a vehicle battery; an oxygen sensor unit for measuring oxygen inside a vehicle through an oxygen sensor and measuring oxygen inside the vehicle by operating according to a signal outputted from the oxygen sensor outputting a quantity of oxygen measured in ppm and the like as an electrical signal and from the power source unit; and a control unit receiving the signal outputted from the oxygen sensor unit, outputs an electrical signal to operate an operating means such as a servo motor so as to open an outdoor air control panel when the quantity of oxygen is a predetermined ppm or less, and enables the operating means such as a servo motor to be operated according to the outputted electrical signal.
