Abstract: In some implementations, a near field communication (NFC) device may determine whether the NFC device is to perform a wireless transaction in a powered mode or an unpowered mode, and may selectively perform the wireless transaction in the powered mode or the unpowered mode based on determining whether the NFC device is to perform the wireless transaction in the powered mode or the unpowered mode. The wireless transaction may be performed using power from a power source internal to the NFC device when the wireless transaction is performed in the powered mode. The wireless transaction may be performed without using power from the power source internal to the NFC device when the wireless transaction is performed in the unpowered mode.

Abstract: The present disclosure relates to systems and methods for using multicomputer data transferring to active contactless communication. In one example, such a system may include at least one memory storing instructions and at least one processor configured to execute the instructions to perform one or more operations, the operations including: receiving a transaction associated with a merchant on a list of merchants stored in the at least one memory; determining, based on the merchant, a remote server associated with the merchant; assembling a data packet including an identifier of the contactless card and an identifier of the transaction; transmitting the data packet to the determined server across one or more computer networks; receiving confirmation from the determined sever in response to the data packet; and transmitting the confirmation to a user device associated with the transaction.

Abstract: Controlling an activation status of a proportional-integral-derivative (PID) controller for an information handling system cooling system, such as the on/off status of the PID controller, can reduce power consumption and processing and memory requirements for such a system. A decrease in resource consumption can be realized by deactivating the PID controller during certain periods and activating the PID controller during others. For example, the PID controller can be deactivated when a temperature of a system component falls below a threshold temperature and activated when the temperature of the system component rises above the threshold temperature.

Abstract: Adjusting a cooling fan speed control profile to account for system implementation factors, such as ambient temperature and usage history, can optimize power consumption and reduce the volume and variation of sound generated by shifts in fan speed in response to changes in system and component temperature. Adjusting a cooling fan speed control profile may include adjusting a maximum fan speed based on an ambient temperature or component temperature of the information handling system.

Abstract: Control signals, such as PWM control signals, can be used to control aspects of a cooling system and can be generated using proportional-integral-derivative (PID) control. PID control systems for cooling systems are designed based on default environmental and system characteristics and pre-programmed for operation prior to delivery to customers or end users. Changes in environmental and system characteristics, such as component aging, environmental variations, and variation in manufacturing from system to system, such as heat sink effectiveness and application of thermal pastes, can impact system level performance of the control system. Adjusting gain parameters for the P, I, and D components of a PID control signal can reduce negative impact on system performance resulting from such changes and allow the control system to better adjust to external factors.

Abstract: A method for cooling system components of information handling systems may include generating a first pulse width modulation (PWM) control signal for controlling at least one cooling fan configured to cool a system component, filtering the first PWM control signal, and applying the filtered first PWM control signal to the at least one cooling fan. The first PWM control signal may be used to control a component fan and then filtered to generate a filtered first PWM control signal used to control a system fan. The filtering of the control signal may include dampening the control signal such that the control signal is less responsive to temperature changes as the temperature nears a set temperature.
