  • Patent number: 11980714
    Abstract: An improved system and method of determining a low water and/or water-out condition in a humidifier chamber of a respiratory or surgical humidifier system can use a specific frequency band to detect changes in a temperature of a heater plate. The temperature changes can correlate to the specific heat capacity value of the humidifier chamber. The low water and/or water-out detection process can be performed without having to determine the gases flow rate and/or can be run continuously. A heater plate assembly of the system can include a compliant insulation sheet to improve thermal coupling between the heating element and the top heating plate of the heater plate assembly, thereby improving the low water and/or water-out detection process.

  • Patent number: 11985177
    Abstract: Systems, methods and products for providing a centralized view of media production devices connected to a network. An example method includes identifying a set of media production devices connected to a network and compiling a list of the identified devices. Network position information is then collected for the identified devices using resources including IS-04 device registries, LLDP tables, FDB tables and ARP tables. For each of the identified devices, a corresponding connection to the network is identified and corresponding network statistics are collected for each of the identified connections of the devices to the network, where the network statistics are correlated to the identified devices. A list of the identified devices is then stored in a searchable format with the corresponding network statistics, and particular ones of the devices may be highlighted to denote conditions indicated by the corresponding network statistics.

  • Publication number: 20240153523
    Abstract: Systems and methods are described for generating a transcript of a legal proceeding or other multi-speaker conversation or performance in real time or near-real time using multi-channel audio capture. Different speakers or participants in a conversation may each be assigned a separate microphone that is placed in proximity to the given speaker, where each audio channel includes audio captured by a different microphone. Filters may be applied to isolate each channel to include speech utterances of a different speaker, and these filtered channels of audio data may then be processed in parallel to generate speech-to-text results that are interleaved to form a generated transcript.

  • Patent number: 11977711
    Abstract: A resource tagging service allows resource tags to be created and associated with computing resources in a service provider network. The resource tags can be utilized to search, collect, filter, organize and otherwise manage computing resources in the service provider network having matching tags, and/or to perform other types of functionality. A resource groups service allows customers and/or other users of the service provider network to view and access collections of computing resources that share common resource tags and/or other attributes. Resource groups can also be evaluated in order to identify computing resources in a service provider network for which certain types of actions or other functionality is to be performed. Membership of resource groups can also be evaluated over time and inferences can be drawn from the membership and from operational information associated with the member computing resources.

  • Patent number: 11975742
    Abstract: Methods of refining a planned trajectory of an autonomous vehicle are disclose. For multiple cycles as the vehicle moves along the trajectory, the vehicle will perceive nearby objects. The vehicle will use the perceived object data to calculate a set of candidate updated trajectories. The motion planning system will measure a discrepancy between each candidate updated trajectory and the current trajectory by: (i) determining waypoints along each trajectory; (ii) determining distances between at least some of the waypoints; and (iii) using the distances to measure the discrepancy between the updated trajectory and the current trajectory. The system will use the discrepancy to select, from the set of candidate updated trajectories, a final updated trajectory for the vehicle to follow.

  • Publication number: 20240134545
    Abstract: Disclosed in some examples are systems, devices, machine-readable mediums, and methods for customizing an in-memory versioning mode for each memory location according to a predicted access behavior to optimize memory device performance. Usage data in a previous time period may be utilized along with policy rules to determine whether to configure a particular memory address as a zero copy or direct copy mode. For example, memory addresses that are read frequently may be configured as direct copy mode to reduce the read latency penalty. This improves the functioning of the memory system by reducing read latency for memory addresses that are frequently read but written to less frequently, and reduces write latency for memory locations that are frequently written to, but not read as frequently.

  • Publication number: 20240136547
    Abstract: A fuel cell electrical power generation system is described herein. The system uses a combustor to increase the pressure and temperature of exhaust gases from a fuel cell stack of the system. The combustor uses hydrogen from a hydrogen supply to provide fuel to the combustor. The increased temperature/pressure of the exhaust gases post combustion are used to rotate a turbine, which in turn rotates a compressor of a turbocharger. The compressor compresses incoming air to increase the power output and/or the efficiency of the system. An ebooster can be used in low load conditions, such as during a startup or during at time in which the electrical loading on the fuel cells is relatively low.
