A computing device determines responsiveness of a user to notification sounds output by the computing device, by determining whether for each notification sound the user acknowledged a notification corresponding to the notification sound on the computing device. The computing device can determine characteristics of the notification sounds output by the computing device. The computing device recommends suggested notification sounds that promote user acknowledgment to notifications, for use in relation to future notifications. The computing device may determine other notification sounds that share the characteristics of the notification sounds for which the user acknowledged the notifications corresponding to the notification sounds on the computing device. The suggested notification sounds can include the other notification sounds, and/or the notification sounds output by the computing device for which the user acknowledged the notifications corresponding to the notification sounds on the computing device.

Recommending notification sounds that promote user acknowledgment to notifications

A method of cleaning a dust filter includes applying a negative electrical potential to a first electrode in a first area of a dust filter and applying a positive electrical potential to a second electrode disposed in a second area of the dust filter, wherein a voltage differential between the first and second electrodes is sufficient to cause electrostatic movement of dust from the first area to the second area. Then, the method further includes applying a negative electrical potential to the second electrode and applying a positive electrical potential to a third electrode disposed in a third area of the dust filter, wherein a voltage differential between the second and third electrodes is sufficient to cause electrostatic movement of dust from the second area to the third area, and wherein the first, second and third areas are generally linearly arranged.

Automated dust filter cleaning

A computer system includes a computer chassis housing a processor and having a dust filter disposed in an airflow pathway through the computer chassis. A plurality of electrodes is disposed across an area of the dust filter, and a voltage source is provided having a negative terminal and a positive terminal. A controller selectively couples a first subset of electrodes to the negative terminal and selectively couples a second subset of electrodes to the positive terminal, wherein a voltage differential between the first subset of electrodes and the second subset of electrodes is sufficient to cause electrostatic movement of dust from an area of the dust filter near the first subset of electrodes to an area of the dust filter near the second subset of electrodes.
