Title: Vacuum coaters and methods of operating a vacuum coater
Inventor: COPELAND NICHOLAS JOHN
IPC: C23C14/58
Filed: 2014-08-27
Abstract: A vacuum coater for coating a polymeric web with metal or metal oxide comprising an unwind, deposition and rewind portion; the coater further comprises a gas injector 16 in the rewind portion for providing gas to the metallised web 18 prior to rewinding the web onto the rewind roller 17.

Further modified PTB7 viz. PTB7 + PCDTBT has been used in combination with PC60BM acceptor, which shows power conversion efficiency (PCE) in the range of 2.5-6% as compared to PCE of 3% or 2% obtained in PTB7/PC60BM or PCDTBT/PC60BM active layer, respectively, in the polymer solar cell. Besides that, the present invention also addresses the development of cost effective and efficient solar cells as PC60BM is cheaper than PC70BM which is currently used with the low band gap polymers for similar PCE achievement.

Title: Embedded computing device
Inventor: ERIK LINDMAN
IPC: G06F3/14
Filed: 2015-04-17
Abstract: A first less power consuming processing core PU1 controls a display DISP via first display interface in phase 430. A second more power consuming processing core PU2 also controls display DISP via a second display interface in phase 410. After a trigger in phase 420, the first core PU1 causes the second core PU2 to enter or leave hibernation 450 in phases 440 and 470, respectively. The second core leaves hibernation if a graphic mode unsupported by the first processor is requested or its communications capabilities are required. Hibernation is entered if reduce map view graphics is required. Context is stored upon transition into hibernation. Both cores can be interfaced with a shared random access memory. Hibernation state is generated by setting the clock frequency to zero. Intermediate low power states allowing faster transitions to an active state are disclosed. Used for conserving battery power in embedded devices, e.g. smartphones.

Title: Axial Flow Pumps
Inventor: William James Beer
IPC: F04D29/44
Filed: 2015-08-12
Abstract: An axial flow centrifugal pump 1 with a body, an inlet 2, an outlet 4 and a rotary drive. An impeller 6 is provided with alternating sets of first curved vanes 7 to generate a pumping action and second vanes 8 to contribute towards straightening of spiral flow of the fluid being pumped, minimising / reducing eddy formation and propagation.

IPC: H04L27/26
Filed: 2018-05-11
Abstract: A method of configuring a reference signal, such as a demodulation reference signal (DM-RS), for a stationary wireless link in a wireless network by activating a reference signal overhead reduction mode if a predetermined condition is met. The predetermined condition may be a message received at a UE or previously measured channel conditions and overhead reduction may further utilize an orthogonal cover code such as OOC 4. A phase tracking reference signal (PT-RS) included in a first slot or subframe may extend across adjacent slots or subframes which do not include DM-RS, whereby PT-RS RB and RE offsets may be chosen to maintain an association of DMRS and PTRS. The stationary wireless link may be a link where there is little or no time variation in the channel and typically be line of sight (LOS). As the channel condition is usually very good, a very high order modulation coding scheme (MCS) such as 1024 QAM may be utilized.
