  • Patent number: 11971845
    Abstract: An encapsulation block for a digital signal processing (DSP) block. The encapsulation block includes DSP block having an input terminal, an output terminal, and an input clock. The encapsulation block also includes pacing control network operatively connected with the input terminal, the output terminal, and the input clock of the DSP block. The input terminal of the DSP block is configured to receive a samples-in data stream inputted at a predefined clock period defined by the input clock. The output terminal of the DSP block is configured to receive a samples-out data stream outputted at a predefined paced parameter. The pacing control network is configured to control data flow at the samples-in data stream and the samples-out data stream independently of the DSP block.

  • Publication number: 20240090604
    Abstract: Various aspects disclosed relate to structure such as a textile, a garment, a garment component, footwear, or a footwear component. The present disclosure includes the structure having a first region having one of more first fibers. An individual first fiber includes co-extruded first and second filaments, the first filament formed of a first thermoplastic polymeric material. Due to expansion or contraction of the one or more first fibers, the first region contracts or expands on a change in relative humidity, relative to an equilibrium state of the first region prior to the change in relative humidity.

  • Publication number: 20230362679
    Abstract: A thermal management controller can be used to alter an operation associated with a network device when a temperature associated with a radio of the network device increases beyond a temperature threshold. A threshold is associated with a state of a plurality of states of the network device. As the temperature increases the thermal management controller to determine whether a current temperature exceeds a temperature threshold associated with the current state of the network device. Based on the determination, the thermal management controller can alter an operation based on the current state and an outcome of the determination. Altering the operation can cause the current temperature to decrease so that the network device can revert to a previous state, for example, a normal or default operation.

  • Publication number: 20230358246
    Abstract: A fan controller for fan of an electronic device can provide dynamic acoustic-based fan control so as to maintain a fan speed so as not to exceed an acoustic threshold. The fan controller can receive one or more temperature measurements associated with the electronic device and can based on these one or more temperature measurements determine an operational temperature of the electronic device. By dynamically and independently controlling the fan speed of a fan of the electronic device based on a determined operational temperature and the acoustic threshold, the electronic device can operate without exceeding the set acoustic threshold while maintaining the operational temperature so as prevent damage to one or more elements of the electronic device.

  • Patent number: 11746180
    Abstract: The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a non-amine catalyst used alone or in combination with an amine catalyst.

  • Patent number: 11663983
    Abstract: Techniques are disclosed for lighting displays such as those associated with electrophoretic display (EPD) devices such as e-readers or any other display technologies or applications. In an embodiment, an EPD device is provided with a number of internal LEDs or other suitable light source generally disposed along at least a portion of the display perimeter. The light can be activated in situations where the available ambient light is inadequate for viewing the display. Light from the light source is distributed across the display, and in some embodiments, can be adjusted to provide a desired degree of brightness. The light can be turned on or off via an existing single press-button or otherwise tactile, physical user interface that serves multiple functions. This user interface can be readily found and engaged by the user without the benefit of sight.
