    摘要： A transporter for transporting a first person and one or more riders over a surface. The transporter includes a first support platform for supporting the first person, the first support platform having left and right sides and defining a fore-aft vertical plane and a lateral plane. At least one ground-contacting element is coupled to the first support platform such that the first support platform is capable of tilting in the fore-aft plane about a tilt axis. The at least one ground-contacting element is driven by a motorized drive arrangement so as to cause locomotion of the transporter. A controller commands the motorized drive arrangement. The controller is configured so that at least one of fore and aft sustained motion of the transporter is based at least on fore-aft tilting of the first support platform. One or more passenger platforms support one or more riders, the passenger platforms coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the one or more passenger platforms.

    摘要： A device for filtering a carrier frequency of a PWM waveform. The device includes a low-pass filter for converting the PWM waveform into an analog signal. The device further includes a sampling analog-to-digital converter receiving the analog signal from the low-pass filter and the device also includes a controller for causing the non-integrating analog to digital converter to sample the PWM waveform at the pulse frequency rate thereby rejecting the carrier frequency. As already stated the PWM waveform includes a pulse which has a leading edge, a top portion, and a trailing edge. In one embodiment, the controller causes the A/D converter to sample during the top of the pulse. Preferably, the controller causes the A/D converter to sample at substantially the center of the pulse.

    摘要： A system and method for generating commands for current subject to dynamic determinations of a limit. In one embodiment, the dynamically determined limit is a function of power dissipation in a component estimated from a measured current level and as a function of a measured temperature proximate to the component. In another embodiment, the limit is a lesser of two dynamically determined current levels. The system and method may be of particular use in a motor having limits determined with respect to a transistor and a motor winding. More particularly, estimated temperatures are established for a transistor and a motor winding for use in dynamically determining limits. Dynamic current limiting may be applied to a left and right wheeled vehicle such that the limit applied to both wheels is the lower of the limits dynamically determined for each wheel.
