  • Patent number: 12291081
    Abstract: A method for operating a refrigeration system having a heat pump function for motor vehicle, including the following steps: setting a heat pump operation, in which the refrigerant is routed from the refrigerant compressor into the secondary line; setting an expansion valve assigned to the third heat exchanger such that a total mass flow of refrigerant flows through the third heat exchanger; and detecting the temperature of the coolant in the third heat exchanger. The total mass flow of refrigerant is routed through the third heat exchanger when the temperature of the coolant is greater than an upper limiting temperature.

  • Publication number: 20240236610
    Abstract: Processing sound in an enhanced reality environment can include generating, based on an image of a physical environment, an acoustic model of the physical environment. Audio signals captured by a microphone array, can capture a sound in the physical environment. Based on these audio signals, one or more measured acoustic parameters of the physical environment can be generated. A target audio signal can be processed using the model of the physical environment and the measured acoustic parameters, resulting in a plurality of output audio channels having a virtual sound source with a virtual location. The output audio channels can be used to drive a plurality of speakers. Other aspects are also described and claimed.

  • Patent number: 12023991
    Abstract: A method for operating a coolant circuit of a refrigeration system of a vehicle having multiple system sections. A single pressure sensor is located in each system section. A temperature sensor is arranged downstream at each component to be balanced in the system sections, such as heat exchangers and a coolant compressor. The sensor signals of the pressure and temperature sensors are supplied to a control unit for the control or regulation of the refrigeration system. Furthermore, a pressure approximation value at the position of the temperature sensor is calculated by a pressure loss value determined using a pressure loss calculation function starting from the position of the pressure sensor arranged in the system section of the component up to the position of the temperature sensor if the temperature sensor and the pressure sensor are arranged at different positions in the system section.

  • Publication number: 20240007820
    Abstract: An audio system and a method of providing a faded audio experience during a transition from a first audio experience to a second audio experience, is described. The first audio experience can include playback of an audio signal spatialized using a first space impulse response that is generated by the audio system. The second audio experience includes playback of the audio signal spatialized using a second space impulse response that is received by the audio system. The audio system generates a hybrid space impulse response based on the first space impulse response and the second space impulse response. During the transition between audio experiences, the hybrid space impulse response is used to spatialize the audio signal to create the faded audio experience. Other aspects are also described and claimed.
