Abstract: A digital glitch filter for filtering glitches in an input signal includes a first flip-flop for generating a filtered output signal, and a self-oscillating circuit for generating a self-oscillating clock signal. A first logic gate enables the self-oscillating circuit when the filtered output signal is not equal to the input signal. A ripple counter generates a divided clock signal by dividing the self-oscillating clock signal. A counter and comparator counts the divided clock signal to obtain a count number and compares the count number with a predetermined count target. A second flip-flop, which is connected to the counter and comparator, generates a valid signal, which is activate when the count number reaches the count target. The valid signal is input to the first flip-flop such that the filtered output signal toggles when the valid signal is active.

Abstract: In one embodiment, a method for managing data includes collecting workload information for a data storage device in a data storage system over a period of time. A peak workload of the data storage device for the period of time is determined. A maximum workload threshold for the data storage device in the data storage system over the period of time is also determined. Movement of additional workload to the device in the data storage system is prevented during a subsequent period of time when the data storage device is predicted to be at about the peak workload for the data storage device in response to a determination that adding the additional workload would cause the workload of the device to exceed the maximum workload threshold.

Abstract: Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).

Abstract: An access point that provides link aggregation is described. During operation, this access point receives a message that may include a Dynamic Host Configuration Protocol (DHCP) response with an Internet protocol (IP) address of a gateway for an electronic device to access a network and a media access control (MAC) address of the electronic device. Based on the MAC address and/or at least a characteristic of the electronic device (such as a configuration, a capability and/or an operating system of the electronic device), the access point may determine a different IP address of another gateway for the electronic device to access the network. Moreover, the access point may modify the DHCP response by substituting the IP address of the other gateway for the IP address of gateway in a modified DHCP response. Next, the access point provides the modified DHCP response to the electronic device.
