  • Publication number: 20050100330
    Abstract: An electric machine drive (50) has a plurality of inverters (50a, 50b) for controlling respective electric machines (57, 62), which may include a three-phase main traction machine (57) and two-phase accessory machines (62) in a hybrid or electric vehicle. The drive (50) has a common control section (53, 54) for controlling the plurality of inverters (50a, 50b) with only one microelectronic processor (54) for controlling the plurality of inverters (50a, 50b), only one gate driver circuit (53) for controlling conduction of semiconductor switches (S1-S10) in the plurality of inverters (50a, 50b), and also includes a common dc bus (70), a common dc bus filtering capacitor (C1) and a common dc bus voltage sensor (67). The electric machines (57, 62) may be synchronous machines, induction machines, or PM machines and may be operated in a motoring mode or a generating mode.

  • Publication number: 20050099083
    Abstract: An electric machine (40, 40?) has a stator (43) and a rotor (46) and a primary air gap (48) has secondary coils (47c, 47d) separated from the rotor (46) by a secondary air gap (49) so as to induce a slip current in the secondary coils (47c, 47d). The rotor (46, 76) has magnetic brushes (A, B, C, D) or wires (80) which couple flux in through the rotor (46) to the secondary coils (47c, 47d) without inducing a current in the rotor (46) and without coupling a stator rotational energy component to the secondary coils (47c, 47d). The machine can be operated as a motor or a generator in multi-phase or single-phase embodiments. A method of providing a slip energy controller is also disclosed.

  • Publication number: 20050057948
    Abstract: A power supply generates alternating current and direct current from a constant-voltage source. A multi-phase pulse width modulation voltage source inverter is connected across the source to output multi-phase alternating current. At least one waveform generator is bridged in parallel with the inverter, with each waveform generator outputting zero-sequence waveform current compensated to maintain the multi-phase current within a predetermined tolerance from a desired set point. A rectifier receives the waveform current and generates direct current.

  • Publication number: 20050001505
    Abstract: A radial gap brushless electric machine (30) having a stator (31) and a rotor (32) and a primary air gap (34) also has at least one stationary excitation coil (35a, 36a) separated from the rotor (32) by a secondary air gap (37a, 37b) so as to induce a secondary flux in the rotor (32) which controls a resultant flux in the main air gap (34). Permanent magnetic (PM) material (38) is disposed in spaces between the rotor poles (A-H) to inhibit the secondary flux from leaking from said pole portions (A-H) prior to reaching the main air gap (34). By selecting the direction of current in the stationary excitation coil (35a, 36a) both flux enhancement and flux weakening are provided for the main air gap (34). A method of non-diffused flux enhancement and flux weakening for the machine is also disclosed.

  • Publication number: 20040002922
    Abstract: Provided herein is a name service that includes published data that is associated with one or more duration entities and one or more modification entities, enabling the name service to more efficiently manage access to published data. To publish data, a publishing client transmits a publication request to a name service. The publication request may specify a modification entity. The name service creates at least one name entry that associates the published data with the modification entity. There are several types of requests to modify data that a name service will honor only when they originate from a modification entity.

  • Patent number: 6594702
    Abstract: Provided herein is a name service that includes published data that is associated with one or more duration entities and one or more modification entities, enabling the name service to more efficiently manage access to published data. To publish data, a publishing client transmits a publication request to a name service. The publication request may specify a modification entity and a duration entity. The name service creates at least one name entry that associates the published data with the modification entity and the duration entity. There are several requests to modify or depublish published data that a name service will honor only when they originate from a modification entity. These are (1) requests to modify published data, and (2) requests to depublish published data. A name service depublishes published data based on the termination of the duration entity that is associated with the published data, when, for example, a garbage collector detects that the duration of an entity has ended.

  • Publication number: 20020103084
    Abstract: The present invention is directed to a concentrated natural pesticide which contains a soybean component. The soybean component can be soybean extract, soybean slurry, soybean powder, or soybean paste. The soybean component is typically diluted with water and then sprayed onto plants to act as an insecticide or to control plant diseases. The concentrated natural pesticide can also comprise a soybean component and a second component which is selected from a group of oils, or an aldehyde such as cinnamic aldehyde. Although foliar application of the diluted pesticide is the preferred application, soil application can also be used.

  • Publication number: 20010055628
    Abstract: The present invention is directed to a natural pesticide, which comprises two oil components. The first component is selected from at least one of the volatile oils and the other component is selected from at least one of the non-volatile oils. Mixing of these two oil components greatly increases the effectiveness for use as a pesticide than if the oils were used separately.
