IPC: G06F1/32
Filed: 2009-09-02
Abstract: A computer implemented method of monitoring the performance of a computer comprises determining S20 the total value of an activity metric of the monitored computer. The contribution to the total value of one or more predetermined activities is determined S22-S28. The contribution is subtracted S30 from the total value to provide a net value representing a measure of the performance of the computer. Similarly, the total values of a plurality of activity metrics may be determined, to provide respective net values representing a measure of the performance of the computer. A data set held in a data store may be used to identify the one or more predetermined activities. An activity metric may be CPU activity or a value of input/output activity and the predetermined activities may be processes. An activity metric may be the number of active network connections or the number of logons. The net value may be used to control the power consumption of the computer.

Title: Virtualisation logic for managing transactions between a physical device controller and a virtual machine
Inventor: BOGIN ZOHAR
IPC: G06F9/455
Filed: 2009-12-24
Abstract: An apparatus comprises a processor (120), a system memory (140), a physical device controller (150) and virtualization logic (132). The physical controller is shared by a plurality of virtual machines (162, 164) created by a virtual machine monitor (160). The virtualization logic (132) is connected to the system memory by a first interface (170). A second interface (180) connects the agent to the physical controller and allows the physical controller to be allocated to the virtual machines as virtual controllers. The logic operates as an agent and is able to inject transactions onto the first interface and the second interface on behalf of the virtual device controllers. In a particular embodiment virtualization logic will trap a transaction (132) and translate or map an address or identifier associated with the physical controller (150) to an address or identifier associated with the virtual machine. Translation, mapping or other processing information may be stored in configuration storage (134) or data storage (136). In this manner virtualization logic (132) may then act as an agent on either interface (170, 180) to inject a new transaction on behalf of that virtual controller.

Title: Improvements in vehicle brakes
IPC: F16D51/26
Filed: 1937-04-08
Abstract: 492,535. Brakes. GENERAL MOTORS CORPORATION. April 8, 1937, Nos. 10007 and 11981. Convention dates, April 8, 1936 and Feb. 1, 1937. [Class 103 (i)] A brake in which two shoes are highly effective in checking forward travel, one only being highly effective in checking rearward travel, comprises an hydraulic device operating one shoe and pivotally mounted on the anchor pin of the second shoe, and an hydraulic device operating the second shoe and pivotally connected with the first shoe. Means for mechanical application of the shoes may be added. In Fig. 1, to apply the brakes, fluid pressure is admitted by aperture 86 to cylinder 39 and thence by conduit 91 to cylinder 59. Cylinder 39 is pivoted on the anchor pin 23 of the second shoe 19, and the piston 43 acts through a cap 55 and pivot 51 to apply the first shoe 17 which anchors on a pin 21 through a link 27 pivoted to the shoe at 25. With clockwise rotation of the drum 11, corresponding to forward travel of the vehicle, the shoe 17 is thus self-actuating ; and the pivotal connection 65 of the cylinder 59 to the link 27 being therefore held, piston 67 applies the second shoe 19, which anchors by link 33 on pin 23 and is also self-actuating. With rearward travel (counterclockwise rotation), the shoe 17 holds cap 55 against cylinder 39, but. cylinder 59, owing to enlarged opening 63, moves bodily to the left to apply the shoe, again in a self-actuating manner. Shoe 19 howeyer, which is acted on only by piston 6 7, is now non-self-actuating. In Fig. 5, the second cylinder 69<1> is not connected to link 27, but is pivoted at 79<1> to a link 77<1> pivoted to the shoe at 81<1>, a roller 831 on link 771 contacting with the rear of the shoe. The link 771 is extended at 77a for emergency mechanical application of the shoes by a cable 871, in which application the cylinder 691 acts as an hydraulic link and the pin 21 acts as the anchorage for both shoes. In Fig. 9 (not shown), the links 27, 33 of Fig. 5 are omitted, the shoes directly engaging their anchor pins.

Title: Determination of the temperature of the working fluid in a steam generator
IPC: G01K13/02
Filed: 1961-03-20
Abstract: 942,486. Viscosity, pressure; temperature and density measurement. SULZER FRERES S. A. March 20, 1961 [March 30,1960], No. 10110/61. Headings G1A and G1N. A method of measuring the temperature of a gas comprises measuring one or more temperature dependent properties of the fluid and deriving the temperature from these measurements, the methods described are by measuring either density or viscosity, together with pressure; if the pressure is not already known. Density measurement Fig. 1. Radiation from the gamma radiation source 4 in the fluid pipe line 1 is detected after its passage through the fluid in detector 12, the output of this detector being compared with the output of detector 14, the output of which is independent of the density of the fluid, and the difference used to drive motor 20 and hence variable thickness shield 23 until the detector outputs are balanced. An electrical output dependent on the density may be extracted from potentiometer 24 mounted on the motor shaft. Viscosity measurement Fig. 3. A rotor 52 immersed in the fluid whose viscosity is to be measured is rotated by the field from coils 53. The speed of rotation depends on the frequency of the AC supply and the viscosity of the fluid in the chamber 50. Magnet 56 rotates with rotor 52 and generates a voltage proportional to its speed of rotation, and hence inversely proportional to the viscosity of the fluid, in coils 57. The output of coil 57 is rectified and compared with the voltage tapped off from potentiometer 52 and the difference energizes motor 60 to eliminate the difference so that shaft 61 is positioned in accordance with the viscosity of the fluid. Pressure measurement and correlation with the other variable to indicate temperature is performed by the apparatus of Fig. 2, in which a spring loaded piston 36 is positioned in accordance with the pressure in pipe 1 and hence positions three dimensional cam 31 longitudinally along shaft 21. The rotational position of the shaft is governed by motor 20 in accordance with density as described with reference to Fig. 2 and hence the cam follower 39 is positioned in accordance with the temperature of the fluid and this indication may be transmitted as an electrical signal by differential transformer 40, 41, 42. Alternatively the rotational position of cam 31 may be determined by the viscosity of the fluid as described above with reference to Fig. 3.

Abstract: 998,890. Time switches. HORSTMANN GEAR CO. Ltd. Feb. 11, 1964 [March 15, 1963], No. 10319/63. Heading H2B. An adjustable tappet arrangement for a time switch of the type wherein a dial 2 rotated by a synchronous motor or clockwork is visible through a transparent cover 1, comprises a shaft 11 keyed by a projection 12 to the hollow dial shaft 2b and fixedly carrying a gearwheel 13. A second gear-wheel 14 of the same diameter but slightly different number of teeth, is rotatable on shaft 11 and has secured to it the adjustable tappet 4. A planet pinion 15 meshing with both gear-wheels 13 and 14 is rotatably mounted on an arm 17 which is rotatably supported on shaft 11. Rotation of a knob 6 (after depression against spring 8) causes an arm 9 to engage a pin 16 and rotate arm 17, thereby rolling pinion 15 around the gears 13 and 14 with resulting reduction drive to the tappet 4, which is thus adjustable between limits set by stops fixed on to dial 2 (Fig. 1, not shown). Back pressure due to tappet 4 contacting switch mechanism (not described) does not move the pinion 15 due to the high reverse gear ratio. Arm 9 is mounted on shaft 7 by means of a friction clutch such that manipulation of knob 6 cannot interfere with the time drive of dial 2.
