Title: Epitaxial liftoff for releasing multiple semiconductor device layers
Inventor: CHENG CHENG-WEI
IPC: H01L21/78
Filed: 2012-09-26
Abstract: A method of removing a plurality of semiconductor device layers from an underlying base substrate is provided. A multilayered stack including alternating layers of sacrificial material layers and semiconductor material layers is formed on the base substrate. Each successive sacrificial material layer that is formed is thicker than the previously formed sacrificial material layer. Because of the difference in thicknesses of the sacrificial material layers, each sacrificial material layer etches at different rates, with thicker sacrificial material layers etching faster than thinner sacrificial material layers. An etch is then performed that first removes the thickest sacrificial material layer of the multilayered stack. The uppermost semiconductor device layer within the multilayered stack is accordingly first released. As the etch continues, the other sacrificial material layers are removed sequentially, in the order of decreasing thickness, and the other semiconductor device layers are removed sequentially.

Title: Monitoring changes in an environment by means of communication devices
Inventor: AMIT KUMAR MISHRA
IPC: G01S7/35
Filed: 2015-04-20
Abstract: Monitoring changes in an environment 202 utilises one or more communication devices 120 (mobile phones) within the environment. Each communication device receives a wireless signal transmitted from a source 140 (base station) and equalises the channels so that transmission by each channel is the same. A central computing device 130, 132 receives channel equalisation information (adaptive filter coefficients, trellis path obtained from minimum entropy trellis decoding) and location from each communication device. The central computer generates estimates of the environment using a neural network, which are recorded to determine changes in the environment over time. A model of the environment may be used. Data relating to a known state of the environment may be stored. The adaptive filter can band-pass filter, perform time recovery to extract data frame timing which identifies information and reference signals, and use the reference signal to train the filter to suppress channel noise / bit error rate.

Patent GB-2544754-A (GB)
Title: Improved fluid coupling
Inventor: MATT READMAN
IPC: F16L21/04
Filed: 2015-11-24
Abstract: A fluid coupling has a first part 100 sealed to a sealing surface of a second part 200, wherein the first part 100 carries a sealing part 300 and the second part 200 includes a gap in the sealing surface, across which the sealing part 300 is arranged to transition. The second part can comprise first and second sections, the gap being formed in a junction between these sections. A vent is provided between the sealing surface and the gap, and can be of a bent fluid passageway form. The aperture is spaced off-set from the gap on the sealing surface. The vent acts to allow fluid to enter the gap before the seal starts to cross the gap and to therefore act to equalise pressure on either side of the seal. Consequently, as the seal transitions across the gap and the sealing between two parts is lost, the fluid pressure imbalance that would otherwise act to deform the seal into the gap has been reduced. The risk of seal damage during the transition has also therefore been reduced.

Title: Methods, apparatuses, and computer programs for data processing, and hierarchical domain name system zone files
Inventor: ELLIOTT MICHAEL BROWN
IPC: H04L29/12
Filed: 2015-12-24
Abstract: Data is processed in a data communications network comprising a hierarchical domain name system. A user (201) enters a domain name e.g. example.com into a web browser. This query is passed via a router (202) to a DNS resolver (203). The resolver recursively queries parts of the domain name starting from the rightmost label i.e. com, and queries a top-level server (204) for the IP address of an authoritative name server (205) for the label com. The resolver then queries the server (205) for the IP address of an authoritative name server (206) for the domain name example.com. The server 206 receives the query from the resolver and supplies contact information for an entity associated with the domain name by obtaining one or more resource records associated with the first domain name. The server (206) then transmits a response to the resolver, which is forwarded to the user. The contact information may comprise a plurality of identifiers by which to contact the entity, e.g. via various social media platforms.

The programmable execution unit selectively stores thread output data in a register(s) of the register memory 4 assigned to the thread, and also calculations of common expressions in the further common local memory (20). A preload unit (17) may store data from an external memory (8) in the local memory (20), and may also store output data for a thread in the local memory. Duplicated write requests to the local memory may be discarded. The use of the local common memory to non-graphic multi-threaded processing units is also disclosed.
