Title: Directory hierarchies and file lists from a plurality of binary images embedded in a computing device are merged to form a composite file system
Inventor: FITZGERALD RICHARD
IPC: G06F12/02
Filed: 2008-06-19
Abstract: A computing device comprises a body of embedded software, such as an operating system, formed as a plurality of binary images for controlling operation of the device, wherein each image contains an independent file system containing a directory hierarchy and file list applicable to the contents of that image, and in which the computing device additionally contains a single merged directory hierarchy and file list applicable to the entire body of embedded software. The composite file system may be constructed before or after the images are embedded and embedded in the device in persistent storage such as NAND Flash EEPROM. Alternatively the composite file system may be constructed when the device is started up and be stored in RAM. The composite file system may be constructed by merging the directory hierarchy and file list of two or more of the images. When two or more versions of the same file are defined in the plurality of images each version may have a precedence order which may be embedded as metadata in the appropriate entry in the file lists and used to determine which file is accessible. Entries in the file list may also include a flag which can be set to indicate that that entry is to be ignored, or never ignored, for searching and listing purposes.

Title: Measurement while drilling tool and method
Inventor: HARVEY PETER R
IPC: H04H60/31
Filed: 2007-04-11
Abstract: An apparatus for telemetering a downhole parameter from a well. The apparatus comprises a housing having a bore. The apparatus further comprises an annular main valve with an enlarged end positioned within the bore, with the main valve having a center of axis.

Title: Variable gain amplifier suitable for gain scaling in an analogue-to-digital converter
Inventor: ZARE-HOSEINI HASHEM
IPC: G06G7/186
Filed: 2008-10-31
Abstract: A variable gain amplifier (VGA) includes multiple input paths, each containing a resistor 118 and a first transistor switch 124 connected between the input Vin and the inverting terminal of an operational amplifier 116. The VGA may be configured as an integrator by means of a capacitor C in the feedback path of the op. amp. 116. The integrating amplifier may form part of an analogue-to-digital converter. The feedback connection is completed via second transistor switches 126, each second switch 126 being connected to a node between an input resistor 118 and a respective first switch 124. Current flowing into the input terminal Vin passes through the feedback circuit and does not flow through first switches 124, thus avoiding problems of non-linearity caused by variations in the on-resistance of the first switches 124. Variations in the on-resistance of the switches 126 in the feedback loop of the integrator are acceptable. The input resistors may be scaled; the switch on-resistances may be correspondingly scaled by varying the area of the transistors used to implement the switches. A differential circuit is also disclosed (fig.4).

Title: Testing optical network transmission path quality via copied test signals
Inventor: MIYAZAKI SATOSHI
IPC: H04B17/00
Filed: 2009-11-30
Abstract: In a virtual concatenation (VCAT) line quality testing apparatus 10, a pseudo-random bit sequence (PRBS) test signal (top line, fig. 3) is generated (11a) and copied into each member signal (VC4 #1-7, fig. 3) of a concatenated signal (VC4-7C) by a control unit (11b, fig. 2) and used to calculate the line quality of two transmission paths 13A & 13B through the network (Routes A & B, fig. 7). The first four VC signals (VC4 #1-4, fig. 3) are sent via one route and the other three (VC4 #5-7, fig. 3) via a second route. This allows efficient and accurate determination of the error rate of each divided transmission path on an individual basis, for Ethernet over Synchronous or Plesiochronous Digital Hierarchy (SDH or PDH), Synchronous Optical (SONET), or Optical Transport (OTN) networks, using only a single PRBS monitoring unit 11c.

Abstract: 697,722. Television. THEILE, R., and CATHODEON, Ltd. April 5, 1950 [April 20, 1949], No. 10538/49. Class 40 (iii). In apparatus for the television transmission of cinematograph film 31 employing a video storage tube 10 of the image iconoscope type, the storage surface 14 is shifted negatively during part of the frame flyback period by submitting it to the combined action of a pulse of electrons and a negative electric field in accordance with the method disclosed in Specification 687,270, [Group XL (a)]. Thus, as shown in Fig. 2, the frame flyback period is divided into two intervals 1-2, 2-3, during the first of which pulses e1 and e2 are applied to cathode-ray tube light source 25 and collector electrode 24 in order to effect the negative charging, and during the second of which a pulse e3 is applied to cathode-ray tube light source 32 to cause an image of the film to be projected on to the photo-cathode 12. Thereafter the charge pattern is evaluated by the scanning beam in a normal manner to generate video signal c interrupted during the line flyback periods by blanking pulses w. The signal passed to amplifier 17 contains large negative and positive pulses a, b and is first restricted within the limits d1, d2 by a circuit, Fig. 3 (not shown), comprising two biased diodes. Information regarding the mean light level of the picture may be retained by a D.C. restorer operating on the line blanking pulses w (peak white) or on peak-black pulses generated by a black strip on one side of the picture. Cathoderay tubes 25 and 32 may be replaced by gasdischarge tubes or light sources obturated by rotating or vibrating shutters. The special construction of storage tube shown in Fig. 3 of Specification 687,270 may be used in which the collector electrode is replaced by secondary emitting collector forming part of an electronmultiplying arrangement.

Abstract: Parallel reinforcing wires are placed in position in production lines and tensioned, a mould is assembled around the wires at the mould-filling station, and the mould is filled with concrete and then slid along the production line (and along the wires).  The mould can slide by reason of the provision of slotted end-plates 23 thereon (see Specification 572,387).  The reinforcing wires are stretched between upright pedestals extending along the line.  The mould-filling station may be at one end of the line, the moulds being assembled around the wires, filled, vibrated, and slid in turn along the wires to the other end, where the concrete is allowed to set; at the setting position the concrete may be vibrated again. Alternatively, the mould-filling station may be at a mid-position in the line, the filled moulds being slid along the wires in either direction.  The moulds may run on rollers, or may be provided with rollers or wheels, or may rest on trolleys having rollers or wheels, or may be partly or wholly supported by the wires.  The filled mould may be slid only far enough to enable a second mould to be brought into filling position, this second mould being coupled to the first, and so on, each succeeding mould being coupled to the preceding mould and the whole train being pulled along the wires step-by-step to the setting station.  There may be several parallel production lines, and the lines may be on more than one level, e.g. in two tiers.  The moulds may be arranged in pairs, side by side.  The apparatus used may be the same as that described in Specification 572,385.  If a hold-up occurs, the wires are cleaned by the attrition device described in Specification 572,396.  Specifications 338,864, [Class 87 (ii)], 364,621, 393,576 and 572,388 also are referred to.
