Abstract: Improved housings for electronic devices are disclosed. An electronic device housing can make use of at least one outer member (e.g., cover) that can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. In one embodiment, an electronic device housing can have one or more outer members (e.g., exposed major surfaces), such as front or back surfaces, that are formed of glass. Protective sides can be provided in some embodiments to protect the edges of the one or more glass surfaces so as to dissipate impact forces and thus reduce damage to the electronic device housing. The one or more glass surfaces can be part of outer member assemblies that can be secured to other portions of the electronic device housing. The electronic device can be portable and in some cases handheld.

Abstract: A method, performed by an access point controls transmission of a data stream from a station, by determining whether or not to admit the transmission of the data stream. The method includes receiving, from the station, a QoS registration request frame, indicating a request for transmission of a data stream, and including information indicating a QoS requirement comprising information indicating a required interval between a start of two successive time periods during which the station is permitted to transmit the data stream. A schedule for the transmission of the data stream subject to the QoS requirement is calculated when the transmission is admitted and a QoS registration response frame, including information indicating the schedule is transmitted to the station.
