Abstract: 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.

Abstract: A method and system for channelizing a Passive Optical Network (PON) Media Access Controller (MAC) includes increasing a clock rate of each of one or more PON MAC(s) to create communication lanes each comprising a plurality of N channels. The PONs are channelized according to NX, where N equals a number of ports supported by the MAC and X equals a designated operating PON MAC clocking rate allowing for leveraging of existing Passive Optical Network (PON) infrastructures to provide a more power efficient and physically smaller MAC layer for OLTs.

A handle is connected to an upper end of the core member. An actuator lever is coupled to the handle and accessible to a hand of the user, the actuator lever being movable between actuated and released configurations. A latching mechanism is situated in the outer tube proximate the open end thereof. A drawbar having an elongate configuration is positioned in an interior of the core member. The drawbar includes a first end coupled to the actuator lever and a second end operatively coupled to the latching mechanism. Operation of the actuator lever operates the latching mechanism to selectively allow length adjustment of the cane.
