Patent GB-2451334-A (GB)
Title: Vertical LED with conductive vias
Inventor: MCKENZIE JAMES STUART
IPC: H01L27/15
Filed: 2008-07-18
Abstract: A light emitting device comprises a network of electrically conductive vias 112 embedded in a multilayer reflector stack , to act as an electrically-conductive, low-loss, high-reflectivity reflector layer (CVMR) 110. The multilayer reflector stack is configured such that at least 60% of light generated in a light emitting region that is incident on the multilayer reflector stack is reflected. The network of electrically conductive elements is configured such that the light generated in the light emitting region, that is incident on the network of conductive element is reflected and is forbidden to couple into localised or propagating surface plasma modes associated with the network of electrically conductive elements. Preferably, the CVMR stack is employed between a reflective metal bottom contact and a p-GaN semiconductor flip chip layer. The CVMR stack may comprise at least 3 layers with at least 2 differing dielectric constants. The conductive vias may be arranged such that localised and propagating surface plasmons associated with the structure reside within the electromagnetic stopband of the CVMR stack, which in turn inhibits trapped LED modes coupling into these plasmonic modes, thereby increasing the overall reflectivity of the CVMR. A light emitting module and method of manufacture are also described.

Title: Fishing Hook
Inventor: CHRISTIE ANDREW
IPC: A01K83/06
Filed: 2009-01-03
Abstract: A fishing hook 1 includes an inbuilt bait attachment device 7, for the purpose of attaching bait to the back of the shank 3. The point 5 and bend 4 are not masked/obstructed by the bait 6 and therefore remain completely effective. The fish therefore finds it more difficult to eject the bait and hook from its mouth, resulting in a higher proportion of hooked fish. The bait attachment device may be in the form of a spike with a barb or a coil/spring like structure. Ideally, the bait attachment device 7 is formed of the same material as the shank 3 and point 5. The size of the point 5 and the bait attachment device 7 may vary depending on usage.

Title: System for protecting data files by monitoring file access events by applications that attempt to manipulate the data in the file.
Inventor: BARILE IAN
IPC: G06F12/14
Filed: 2009-10-30
Abstract: Disclosed is a method for protecting the files and the data in the files by monitoring and classifying the behaviour of applications based on their data access patterns. The method includes monitoring file access events associated with an application, and determining whether any of the file access events indicates the application's attempt to manipulate data in the file. If a file access event indicates that the application has attempted to manipulate the data within the file, then an action is performed. The action to be performed includes scanning the file for confidential information and then restricting file read requests. If the file access attempt is an request for the file metadata, then the request is allowed. The application may be one of a disk burning, data compression, a browser or a cloud storage application. The file access events may be received via a filter driver or a network-based application sniffing network traffic, and the each file access event identifies the file and specifies a read block size and read offset.

Class 6(iii) A draw-bar for attaching mowing machines to a tractor as in Specification 664,229 and for supporting the operating mechanism is formed of several units secured to a frame to form a rigid structure which can readily be dissassembled to replace any unit, the frame consisting of parallel spaced plates extending transversely. The several units are clamped between the plates and act as spacers for the plates. The units include a bearing C for the main drive shaft, a bearing F for a countershaft, a support bracket I for a pulley in the counterbalancing means and a connection for the drag link, all the units being placed between parallel plates A, B. The unit C, which acts as a spacer, is secured by bolts D entering slots E in the plates A, B. The unit F, which is secured to the plates by bolts, has a bearing portion F' passing through apertures G, Fig. 7, in the plates A,. B. Below the bearing F<SP>1</SP> is a portion F<SP>6</SP> with a bore F' for receiving a pivot pin (not shown) for engagement with a link on the tractor.' On the opposite side of the central unit C is the unit I with a bracket arm I<SP>1</SP> provided with a bearing I<SP>2</SP> for a pin (not shown) on which a pulley is mounted. Above the bearing is a guard I' for the pulley. The unit has a lower part I<SP>5</SP> secured between the plates by clamping bolts. Beyond the part I<SP>5</SP> is a portion I<SP>6</SP> similar to the part F<SP>6</SP> and receiving a pivot pin in a bore F.

Filed: 1924-04-24
Abstract: 237,953. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E., (Automatic Electric Co.). April 24, 1924. Automatic exchange systems.-In the case of a dead number or faulty line, the line switch cutoff relay is disconnected from the test terminal, with the result that the call is extended over conductors 47, 48 and switches LF, TS to an operator's position Y. A piece of insulating material is placed between springs 70 in the case of a dead number, while a plug P<2> is inserted in the case of a faulty line to connect up the high frequency apparatus T to light a lamp L' in the operator's cord-circuit. Means are provided for delaying the setting up of the connection over the switches LF, TS. Dead number call. Switching relay 17 fails to energize, and when stepping relay 16 falls back, a start relay 100 operates over the upper winding of relay 17 (now inoperative) and a resistance 99, but attracts only armatures 102, 103. Earth is thereby removed from a multiple terminal of the finder-switches LF, and relay 110 energizes. Twostep relays 111. 112 now energize in turn over interrupter I and look to delay the setting up of the connection. The magnets 139, 156 of a pair of switches LF, TS are then connected up over wipers of the allotting switch FD, switching relays 113, 114 being connected to test wipers 153, 164 in the usual way to enable hunting to take place. When relays 113, 114 are both energized, circuits are closed for the magnet 104 of the allotting switch and relays 115, 140. The latter conneets the talking wires to the operator's position and connects test wipers 153, 164 to wire 158. Line relay 172 energizes, connects ring-back tone to the calling line, lights lamp L and earths test wire 150. Relay 100 now energizes fully over test wire 155, removing earth from start wire 175 and short-circuiting switching relay 17. Relays 110, 111, 112, 113, 114 now relapse, opening the energizing circuit of the magnet 104 and relay 115 to advance the switch FD to the next idle link circuit. start wire 175 being meanwhile disconnected. When the operator plugs in, relays 174, 158 energize, cutting out ring-back tone and lamp L. Sleeve relay 170 energizes, and connects up relay 171 which prevents lighting of lamp L<1>. The operator converses with the calling subscriber, and release takes place in the usual way, relays 100, 140 being disconnected at rotary off-normal contacts 45. Call to a faulty line. The connection to the operator's position is set up as before, but, upon plugging in, an A.C. relay 162 energizes over the test circuit 150, 155, 46, P<2> and prevents operation of relay 171, so that lamp L<1> lights. The operator may be provided with an ordinary cordcircuit, and test for high-frequency current on the sleeve of the jack upon plugging in.
