摘要:
A system can include one or more processors and one or more non-transitory computer-readable media storing computing instructions that, when executed on the one or more processors, cause the one or more processors to perform operations: receiving a new notification; determining, using a binary search algorithm, a number of one or more notifications, wherein an interval of the binary search algorithm comprises a time period between a reclamation pointer and an ingestion pointer; when the number of the one or more notifications is greater than a maximum number of notifications, removing, from a central data store, at least one notification of the one or more notifications; and storing the new notification in the central data store. Other embodiments are described.

Provided herein are a pin sharing circuit, a pin sharing method and an electronic device, an electronic wire using the same. The pin sharing circuit enables at least one pin on an integrated circuit to be shared by a keyboard device and a touch panel and prevents signal interference between the keyboard device and the touch panel using an impedance element disposed on a wire for the pin, such that the pin can output or receive a stimulation signal and a sensor signal that contain both an AC component and a DC component so as to enhance the efficiency of the overall system and prevent the stimulation signal and the sensor signal from conflicts between the keyboard device and the touch panel.

A serial peripheral interface of an integrated circuit includes: a first transfer pin for receiving an instruction and an address; and a clock pin for inputting a plurality of timing pulses each having a rising edge and a falling edge. After the first transfer pin receives the instruction, the integrated circuit receives the address through the first transfer pin in continuity with the receipt of the instruction. The first transfer pin receives the instruction at either of the rising edges and the falling edges of the timing pulses and receives the address at both of the rising edges and falling edges of the timing pulses.

This specification describes an integrated circuit comprising: a single wire interface; a clock circuit configured to detect a voltage from the single wire interface and to generate a clock signal having a frequency that is based on the detected voltage; and a digital system coupled with the single wire interface and the clock circuit. The digital system is configured to: receive a data signal from the single wire interface; power the digital system using a power signal from the single wire interface; and perform one or more operations clocked by the clock signal.

A single wire serial interface for power ICs and other devices is provided. To use the interface, a device is configured to include an EN/SET input pin. A counter within the device counts clock pulses sent to the EN/SET input pin. The output of the counter is passed to a ROM or other decoder circuit. The ROM selects an operational state for the device that corresponds to the value of the counter. In this way, control states may be selected for the device by sending corresponding clock pulses to the EN/SET pin. Holding the EN/SET pin high causes the device to maintain its operational state. Holding the EN/SET pin low for a predetermined timeout period resets the counter and causes the device to adopt a predetermined configuration (such as off) until new clock pulses are received at the EN/SET pin.

An integrated circuit within an integrated circuit package, including a configuration module and a timing module. The configuration module configures the integrated circuit using a configure operation performed via N pins of the integrated circuit package, where N is an integer greater than 1. The timing module is configured to control on/off timing of (N*M) light emitting diodes arranged in N columns and M rows connected to the N pins and M pins of the integrated circuit, respectively, where M is an integer greater than 1. During a first period, the configure operation utilizes the N pins. During a second period, the N*M light emitting diodes receive data from the M pins and refresh signals from the N pins. The second period is different than the first period.

Systems and methods for detecting states are disclosed. An information handling system may include a processor and a plurality of information handling resources communicatively coupled to the processor via the common control line. The processor may be configured to produce a first signal on a common control line. Each of the plurality of information handling resources may include a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag.
