Abstract: A cooling system for an electrified vehicle includes a first cooling loop for circulating coolant for cooling at least one of power electronics and a motor/generator of the vehicle. The first coolant loop includes a heat exchanger for exchanging heat with the coolant in the first cooling loop. A second cooling loop is provided for circulating coolant for cooling a battery of the vehicle. The second cooling loop includes a coolant chiller connected to a refrigeration system of the vehicle for exchanging heat in the coolant received from the battery with the refrigeration system of the vehicle.

Abstract: A method and system of equalizing in a decision feedback equalizer is provided. A plurality of adder circuits receives a digital code representing a previously decided symbol from an output of a prior path of a plurality of paths. A decision-making slicer circuit receives an input voltage and a first clock signal. The plurality of adder circuits receives a second clock signal and injects an offset current proportional to the digital code representing the previously decided symbol into a current injection input of the decision-making slicer circuit, at a first edge of the second clock signal. There is a predetermined skew between the first clock and the second clock to control a timing between the injection of the offset current of the plurality of adder circuits and the initiation of a decision-making phase of the decision-making slicer circuit.

Abstract: A system for transferring electric energy to a vehicle, in particular to a track bound vehicle such as a light rail vehicle, includes an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring electromagnetic energy to the vehicle. The vehicle includes at least one receiver for receiving the electromagnetic energy and at least one signal transmitter adapted to repeatedly or continuously emit an enable signal towards the track. The vehicle also includes a transmitter control arrangement adapted to stop transmitting the enable signal if the receiver or if any device combined with the receiver is not to be operated.

Abstract: An accumulator for an air conditioning system has a passage for oil to travel from an orifice to an outlet. To improve the percentage of oil flowing from the orifice to the outlet and/or the rate of flow, one or more oil vanes extend from or near the orifice to or near the outlet. Alternatively, instead of oil vanes, indentations could be used.

Abstract: An accumulator for an air conditioning system is adapted to ensure that any fluid exiting the accumulator has been filtered. Fluid comprising gaseous refrigerant, liquid refrigerant and oil enters the accumulator. Ideally, only gaseous refrigerant and oil will exit the accumulator. According to one embodiment, gaseous refrigerant is substantially separated from liquid refrigerant. Oil is entrained within the gaseous refrigerant. The gaseous refrigerant with the entrained oil is filtered prior to exiting the accumulator. In another embodiment, gaseous refrigerant, which has been separated from the liquid refrigerant, is filtered before the oil is entrained with it. The oil is then separately filtered.

Abstract: A deflector for an accumulator for an air conditioning system acts as a barrier to substantially prevent incoming liquid from entering a conduit which is primarily for gas. Fluid entering the accumulator comprises gas and liquid. The deflector also assists with the separation of gas from liquid, with reduced turbulence, to decrease the likelihood of liquid becoming re-entrained within the gas. An initial contact surface of the deflector receives the incoming fluid. The initial contact surface is substantially convex, so that liquid reflecting off the surface will be travel in a direction away (or different) from the flow of incoming fluid. The initial contact surface is also angled to direct liquid reflecting off it (or flowing down it) downward and outward.

Abstract: A suction accumulator for refrigeration or air-conditioning system use, especially for automotive air conditioning system use, which comprises a “pickup tube” to withdraw liquid from a reservoir of the accumulator to return oil to the compressor. The accumulator has a deflector with an outlet tube, to help ensure that fluid does not flow directly from the inlet opening to the outlet opening of the accumulator. The relatively narrow second portion of the outlet tube is closer to the outlet opening than the first portion. The pickup tube is secured in communication with the relatively narrow second portion and optimises the oil return function, minimises restriction to refrigerant flow, maximises effective and actual reservoir volume, and minimises the amount of liquid delivered to the compressor at switch-off.
