Title: Full visibility warning flag for motor sports
Inventor: GEOFFREY JAMES DOBBERSON
IPC: G09F17/00
Filed: 2015-01-18
Abstract: A flag 3 may be made from a perforated air permeable non water absorbent plastic mesh material 9. The material may form sleeves at either end into which tubular or rod like means 2 and 5 may be inserted. Item 5 may be attached via a ferrule 6 to a shaft 7 and handle grip 8. The ferrule may act to allow the flag to rotate about the shaft and handle and the ferrule may be adjusted up and down the shaft to accommodate different flag sizes. The purpose of rods 2 and 5 is to stiffen the face of the flag allowing it to remain unfurled in windy conditions. The flag may be used in motorsports where the fully deployed face is advantageous in allowing drivers to see the nature of the flag that is being deployed.

Title: Fuel cell flow channels and flow fields
Inventor: LEGER DAVID EARL
IPC: H01M8/10
Filed: 2013-08-14
Abstract: A fuel cell anode flow field comprises at least one flow channel with a cross- sectional area that varies along at least a portion of its length. In some embodiments, the channel width decreases along at least a portion of the channel length according to a natural exponential function. This type of anode flow field may improve performance, reduce fuel consumption and/or reduce detrimental effects such as carbon corrosion and catalyst degradation, thereby improving fuel cell longevity and durability. When operating the fuel cell on either a substantially pure or a dilute fuel stream, this type of anode flow field may provide more uniform current density, which is desirable for efficient fuel cell operation and improved fuel cell performance and lifetime. Variants of the non-conventional reactant flow channels are described, along with examples of incorporating such flow channels into reactant flow field plates, fuel cells and fuel cell stacks.

Title: Method of intialising physical downlink control channel (PDCCH) for eMTC and IoT devices
Inventor: SIVA SUBRAMANI
IPC: H04W74/08
Filed: 2015-11-12
Abstract: In a wireless telecommunications system, a terminal determines a repetition number based on a reference signal received power (RSRP) from a base station. The terminal transmits a physical RACH (PRACH) request message which includes an indication of the repetition number and an identifier for the device. On receiving the request, the base station generates a random access response message (RAR) and scheduling data for at least one control message. The scheduling data is generated in accordance with the indicated repetition number. The at least one control message is transmitted in accordance with the scheduling data. The embodiment relates to coverage enhancements in LTE for low complexity devices such as narrowband internet of things (NB-IoT) or MTC devices. Devices with a poor coverage class receive PDCCH messages with greater repetition. .

Title: Data storage
Inventor: CEDRIC DENIS ROBERT AIRAUD
IPC: G06F12/1027
Filed: 2016-02-25
Abstract: A processor addresses a location in memory using indexed addressing with a base address and an offset. The processor compares the location address with a test address. The test address may be a tag in a cache or a translation look-aside buffer. The processor adds 320 part 350 of the offset to the corresponding part 340 of the base address. The result is compared 320 with the corresponding part 360 of the test address. The bits 390 of the base address, which are more significant than the part that was added, are compared 310 with the corresponding bits 380 of the test address. If both comparisons match 370, then a hit signal 300 is generated. The processor may generate an abort signal 250 if the hit signal was generated in error. This may depend on the carry 420 from the addition.

Title: Method of assessing damage to composite members
Inventor: MARTIN ROBERT PEEL
IPC: G01N19/08
Filed: 2016-06-16
Abstract: A method of checking for damage to a composite panel requires the formation of composite panel comprising at least one cavity. A first pressure differential is then established between the cavity and the surrounding ambient pressure. The rate of change of the pressure differential over a first predetermined period is monitored and then the pressure differential is allowed to subside. The result of the monitoring step is stored as a reference value, so that after the composite member is damaged, or after it has been in service for a predetermined time, the test can be repeated and compared with the reference value. If the result of the repeated monitoring differs from the reference value by more than a predetermined amount, it is determined that the composite member is defective and leaking. The composite member may be the component of an automobile body and made from fibre reinforced plastics or a carbon composite.
