Abstract: A thermal imaging camera having improved durability and ergonomic features including generally a seamless housing encompassing a thermal imaging core, a first handle, and a battery compartment. The housing is preferably positioned at a first end of the first handle and the battery compartment is positioned at the opposite end of the first handle. By positioning the first handle intermediate between the housing and the battery compartment, the center of gravity of the thermal imaging camera coincides generally with the handle when the thermal imaging camera is in use, that is when batteries are present within the battery compartment. The camera can also include a second handle positioned between the housing and the battery compartment, the second handle is preferably oriented generally parallel to and spaced apart from the first handle to facilitate passing of the thermal imaging camera between users. The camera also has improved water resistance, shock-resistance and other operational features.

Abstract: A friction material especially for use in conjunction with aluminum alloy brake rotors containing silicon carbide particles contains 15 to 80% of a finely divided alumina abrasive, from 5 to 40% of cured organic binder, less than 5% metal in particulate form and less than 5% particulate carbon and/or graphite, from 1 to 40% of organic fiber the balance being particulate inert filler and optionally, a non-graphitic lubricant, all percentages being by volume.

Abstract: A method and apparatus for the sensorless determination of commutation position in a brushless motor. The electric current flowing within the active, or energized, stator coil during energization is differentiated to produce a current rate of change waveform. The current rate of change waveform is compared to a predetermined voltage threshold which is set to approximate the point at which the rotor is in direct positional alignment with the active stator. From this comparison, it is determined when the current rate of change waveform fails to intersect the predetermined voltage threshold. This information may be used to commutate the application of a driving signal to the next stator coil in succession to maintain continuous torque on the rotor. This information may also be indicative of a stalled condition, in which case a stall indicator is triggered to alert the user of the stalled condition.
