    摘要: A method of controlling the operation of a loader to encourage the use of an operator restraint mechanism is disclosed wherein a first signal is generated by a seat sensor to indicate the presence of the operator in the operator seat and a second signal is generated by a sensor in the operator restraint mechanism to indicate use of the mechanism. The hydraulic system will not be enabled unless the second signal is generated immediately subsequent to the generation of the first signal. Unless the first and second signals are generated in the proper sequence, the starting of the engine will also be disabled. The generation of first and second inverse signals, indicating the lack of the presence of the operator in the seat and the disengagement of the operator restraint mechanism, respectively, will disable the loader hydraulic system. A delay is provided to permit the operator to vacate the seat for a short period of time without having to resequence the generation of the first and second signals to enable the loader hydraulic system.

    摘要: An atomic force microscope (AFM) tip is used to selectively produce surface enhanced Raman scattering (SERS) for localized Raman spectroscopy. Spectra of thin films, undetectable with a Raman microprobe spectrometer alone, are readily acquired in contact with a suitably gold-coated AFM tip. Similarly, an AFM tip is used to remove sample layers at the nanometer scale and subsequently serve as a SERS substrate for ultra-trace analysis. This demonstrates the interface of an AFM with a Raman spectrometer that provides increases sensitivity, selectivity and spatial resolution over a conventional Raman microprobe. An AFM guiding the SERS effect has the potential for targeted single molecule spectroscopy.

    摘要: A loader having hydraulically operated boom and bucket mechanisms controllable from the operator seat is disclosed wherein switches sense the presence of the operator in the seat and the buckling of the seat belt. An electronic controller is operably associated with the seat and belt switches and solenoid valves in the hydraulic system and the starter relay. The controller requires proper sequencing of the activation of the seat and belt switches before permitting the starter to be energized, thereby controlling the starting of the loader engine, or permitting the energizing of the hydraulic solenoid valves to control the flow of hydraulic fluid to the hydraulic cylinders for the boom and bucket. The controller also includes a delay associated with the seat switch so that a reactivation of the seat switch within the delayed period of time would allow the hydraulic system to operate without requiring a resequencing of the activation of the seat and belt switches.

    摘要: This invention relates to a hybrid lawn mower powered by a fuel cell and an electrical storage system, both of which supply electric power to the drive wheels and cutting units of the mower. The electrical storage system comprises an ultracapacitor pack or a battery pack. The electric motor driving each cutting unit comprises a brushless motor having an integrated gear reduction stage. In addition, the motor includes an integrated electronics housing in which the electronics for controlling and powering the motor are packaged. The cutting units are lifted out of engagement with the ground by a lift and lower system comprising an electric/hydraulic actuator that is driven only during lifting of the cutting units. The cutting units are lowered by releasing fluid pressure in the lift and lower system and permitting the force of gravity to lower the cutting units.

    摘要: A walk reel mower has a front mounted reel cutting unit and a rear handle. The operator pushes the handle towards the ground to lift the reel cutting unit off the ground prior to turning the walk reel mower around. When this occurs, the manner in which the reel cutting unit is supported in conjunction with the influence of gravity causes the reel cutting unit to pitch rearwardly relative to the frame of the walk reel mower. This change of orientation is used to close a switch which, in turn, initiates an automatic slow down of the mower to ease the task of turning the mower around. When a turn is completed and the cutting unit is dropped back down into engagement with the ground, the slow down is terminated and the ground speed resumes at whatever predetermined ground speed was previously selected by the operator.
