  • Patent number: 11907008
    Abstract: A communication apparatus includes a communication circuit, a clock supply circuit, a CPU and a memory storing a program which, when executed by the CPU, causes the communication apparatus to function as a control unit which causes the communication circuit to operate in one of a first mode in which the communication circuit performs a normal communication with the external apparatus and a second mode in which the communication circuit operates with lower power consumption than in the first mode. In the second mode, the control unit controls the clock supply circuit so as not to supply the clock signal to the communication circuit. While the communication circuit is operating in the second mode and the clock signal is not being supplied to the communication circuit, the control unit controls the clock supply circuit to start supply of the clock signal to the communication circuit in response to a predetermined signal.

  • Patent number: 11841697
    Abstract: Described herein are methods and manufacturing systems that select fasteners for pre-feeding and, in some examples, pre-feed the selected fasteners. These methods involve aggregating historical manufacturing data, comprising hole identifications and fastener grip lengths, previously selected for these hole identifications. A specific grip length and a corresponding fastener repeatability rating are then determined for each hole identification from this historical manufacturing data. For example, a specific grip length corresponds to the most frequently selected grip length for this hole identification. In some examples, the historical manufacturing data is analyzed using machine learning. The fastener repeatability rating is compared to an operating threshold, in some examples, to determine if the corresponding grip length should be selected for a particular hole location.

The power consumption reduction circuit includes a frequency reduction control chip. The frequency reduction control chip, after receiving an overpower alarm signal generated by a Power Supply Unit (PSU), generates a frequency reduction control signal to a Power Break (PWRBRK) pin of each GPU so as to start a frequency reduction operation of each GPU. It can be seen that, in the present application, an underlying hardware circuit is directly used for implementation with relatively quick responses and without intervention of an operating system, whereby the whole frequency reduction operation of the GPU may be completed within 5 ms, and the PSU is prevented from triggering overpower protection within relatively short time. Therefore, loss of service data of a user caused by an exceptional power failure of the server is avoided.

  • Patent number: 11539203
    Abstract: A system and method of protecting the input components of a power supply. An input overcurrent protection module is provided, which may be implemented in firmware, which monitors the input current through an input interface of the power supply. When the input current exceeds a threshold current (i.e., a current above the maximum rating of an input component, such as an input cable), the input current protection module determines whether an input overcurrent event is occurring. When it is determined that an input overcurrent event has occurred, the input current protection module disables the output circuitry of the power supply and triggers a few timers. The input overcurrent protection module continues to monitor the input and, if the input current continues to exceed the threshold current, is configured to shut down the power supply. In this way, input components may be protected from overcurrent issues in high-power systems.

  • Patent number: 11397458
    Abstract: A data processing apparatus comprises a plurality of processor circuits to process an event stream comprising one or more high energy events. Each of the plurality of processor circuits draws power from a same power rail. Power management circuitry performs power consumption management by controlling a voltage supply to the power rail, and a frequency of a clock signal provided to the plurality of processor circuits. Status analysis circuitry obtains a status of the individual processing load of each of the processor circuits and restriction circuitry performs high energy event restriction on each of the plurality of processor circuits. The power consumption management and the high energy event restriction are both based on the individual processing load of each of the plurality of processor circuits and each of the processor circuits is restrictable by the restriction circuitry independently of others of the processor circuits.

  • Patent number: 11360820
    Abstract: Systems and methods are disclosed for scheduling threads on an asymmetric multiprocessing system having multiple core types. Each core type can run at a plurality of selectable voltage and frequency scaling (DVFS) states. Threads from a plurality of processes can be grouped into thread groups. Execution metrics are accumulated for threads of a thread group and fed into a plurality of tunable controllers. A closed loop performance control (CLPC) system determines a control effort for the thread group and maps the control effort to a recommended core type and DVFS state. A closed loop thermal and power management system can limit the control effort determined by the CLPC for a thread group, and limit the power, core type, and DVFS states for the system. Metrics for workloads offloaded to co-processors can be tracked and integrated into metrics for the offloading thread group.

  • Patent number: 11243601
    Abstract: Techniques are disclosed regulating an amount of power consumed by a server from a set of power supplies in which at least one power supply of the set is inactive. The power to a server, upon detecting that at least one power supply is inactive, is restricted based on a degree to which a power threshold value for the remaining power supplies is exceeded. The applied power reduction may be based on a proportion of a measurement interval during which an alert signal is received. The longer the alert signal is received by the system, the more server power consumption is reduced.
