Abstract: A bimodal lithium transition metal oxide based powder mixture comprising a first and a second lithium transition metal oxide based powder. The first powder comprises a material A having a layered crystal structure comprising the elements Li, a transition metal based composition M and oxygen and has a particle size distribution with a span <1.0. The second powder has a monolithic morphology and a general formula Li1+bN?1-bO2, wherein ?0.03?b?0.10, and N?=NixM?yCozEd, wherein 0.30?x?0.92, 0.05?y?0.40, 0.05?z?0.40 and 0?d?0.10, with M? being one or both of Mn or Al, and E being a dopant different from M?. The first powder has an average particle size D50 between 10 and 40 ?m. The second powder has an average particle size D50 between 2 and 4 ?m. The weight ratio of the second powder in the bimodal mixture is between 20 and 60 wt %.

Abstract: A bimodal lithium transition metal oxide based powder mixture comprises a first and a second lithium transition metal oxide based powder. The first powder comprises particles of a material A comprising the elements Li, a transition metal based composition M and oxygen. The first powder has a particle size distribution characterized by a (D90?D10)/D50<1.0. The second powder comprises a material B having single crystal particles, said particles having a general formula Li+bN??bO2, wherein ?0.03?b?0.10, and N?=NixM?yCozEd, wherein 0.30?x?0.92, 0.05?y?0.40, 0.05?z?0.40 and 0?d?0.10, wherein M? is one or both of Mn or Al, and E is a dopant different from M?. The first powder has an average particle size D50 between 10 and 40 ?m. The second powder has a D50 between 2 and 4 ?m. The weight ratio of the second powder in the mixture is between 15 and 60 wt %.

Abstract: A method (200) and apparatus (100) that synchronizes audio levels of a device and an audio accessory is disclosed. In at least one embodiment, the apparatus (100) includes a housing (110) and a local speaker (130) coupled to the housing. The apparatus also includes a wireless speaker interface (180) coupled to the housing. The wireless speaker interface can be configured to send an audio signal to a remote separate speaker module wirelessly coupled to the wireless speaker interface and can be configured to send and receive volume level status data to and from the remote separate speaker module. The apparatus further includes a volume adjustment user interface (160) that can receive a user input to adjust the volume level of the remote separate speaker module. The apparatus additionally includes a controller (120).

Abstract: The invention provides for a closeable radio communications device (1) comprising a housing (21) having at two portions (22,23) pivotally mounted to each other to allow relative movement of the portions between a closed position and an opened position. There is a spacing projection (30) on one of the two portions (22,23), the spacing projection (30) being configured such that when the housing (21) is in the closed position an acoustic chamber (31) is formed by an inner surface (32) of the projection and facing surfaces (27,28) of the respective portions (22,23). A speaker (5d) mounted inside the housing (21) is in operative communication with the acoustic chamber (31).
