摘要： A method and apparatus for catching a rotating motor is described. Switches (typically the lower switches) of an inverter of a motor drive circuit are short-circuited for a brief period of time. The pulses generated by this process are analyzed to determine the speed and direction of rotation of the motor. The pulses are checked to determine whether they are orthogonal. If they are, the motor velocity determination is deemed to be reliable and then motor is magnetized and normal motor control can be resumed. If not, the motor velocity determination is deemed to be unreliable and a magnetization pulse before the velocity determination step is repeated.

摘要： A battery-operated light bulb can be used as (i) a regular light bulb, inserted into a standard light socket to be powered off an electrical grid; (ii) an automatically battery back-up emergency and safety light bulb for operation when the electrical grid is offline; and (iii) a portable flashlight when separated from the light socket. The light bulb is also equipped with a motion sensor for turning on the light bulb when movement is detected; a timer for turning off the light bulb after a preset time period, and an ambient light sensor for adjusting the intensity of the light bulb depending on ambient light levels, with all of which the operation of the light bulb can be controlled so as to conserve power, to preserve battery life so it is available when needed in emergency situations, and to prolong the life of the bulb.

摘要： Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

摘要： A heat exchanger (10) of a heat exchange device used for air cooling cold water units or commercial roof machines, a method for manufacturing the heat exchanger (10), a heat exchange module, a heat exchange device, and a heat source unit. The heat exchanger (10) comprises: a main body portion (ab); a bent portion (cd) with a trapezoid cross section, the bent portion (cd) and the main body portion (ab) being connected and approximately perpendicular to each other; two collecting pipes (11, 12), disposed on two opposite sides of the heat exchanger (10); and multiple heat exchange pipes (13), each extending from one collecting pipe (11) of the two collecting pipes (11, 12) to the other collecting pipe (12) by passing through the main body portion (ab) and the bent portion (cd), wherein a top edge of the bent portion (cd) and a top edge of the main body portion (ab) of the heat exchanger (10) are approximately located at the same height level.

摘要： An apparatus for compaction of soil and asphalt includes a first mass, such as a compaction drum, or vibrating plate, a second mass configured to oscillate vertically and an unbalanced shaft configured to vibrate the first and second masses. Wherein removable masses can be added and removed from the second mass, in order to enable resonance vibration of the first and second masses, thereby doubling and even tripling the compaction forces applied to the surface being compacted.

摘要： A method of cleaning a substrate (16, 24, 34, 64, 71, 82, 102, 165, 171, 181, 201, 300, 310) with optical energy can comprise applying optical energy from a source of optical energy (12, 21, 31, 91, 103, 114, 121, 131, 141, 151, 164, 191, 202) to the substrate. The method can comprise applying the optical energy to a substrate having a cleaning agent applied thereto, the optical energy having one or more optical parameters selected for cleaning the substrate. The method can comprise reading data from a data bearing element (173) associated with the substrate, communicating the data to a processor (154) associated with a cleaning appliance (10, 30, 40, 60, 70, 80, 90, 110, 120, 130, 140, 150, 161, 200) comprising the source of optical energy, wherein the processor, responsive to the communicated data, controls the cleaning of the substrate with the optical energy. The method can comprise slidingly contacting the substrate with a work surface, said work surface comprising an aperture (83, 117) and emanating optical energy from the aperture for cleaning the substrate. A cleaning appliance can comprise an appliance body (80, 90, 104, 125) comprising an aperture for emanating optical energy for cleaning the substrate and an optical transmission pathway arranged for propagating optical energy received from an optical energy source to said aperture. The appliance can be adapted and constructed for delivering a cleaning agent to the substrate. The appliance can include a processor, a data interface in communication with the processor, and can be configured such that the processor outputs signals that control the cleaning of the substrate, the processor being configured for controlling, responsive to data received by the data interface and via the output signals, the substrate cleaning. The cleaning appliance can include a suction pump (142) for removing material from the substrate.

摘要： A hydraulic machine is provided comprising a cylinder unit (3) having a plurality of cylinders (4a, 4b) which are located on a circle line around an axis of rotation of said cylinder unit (3), a valve plate (6) located at an axial end of said cylinder unit (3) and having a through-going opening (8) for each cylinder (4a, 4b), and a port plate, said valve plate (6) and said port plate resting against each other in sliding contact at a contact face, wherein a pressure in each cylinder (4a, 4b) acts on a pressure area on a side of said valve plate (6) opposite said port plate. In such a hydraulic machine the risk of leaking should be kept small. To this end said pressure area (17) deviates from a circular form.
