Abstract: A foldable fork of a bicycle, comprising a stem having a first end and a second end; a pair of prongs configured to receive an axle of a bicycle wheel; and a pivot having an axis that is angled with respect to the axle of a bicycle wheel when connected to the prongs, the pivot connected to the second end of the stem on a top section of the pivot and connected to the pair of prongs on a bottom section of the pivot. The top section of the pivot is configured to receive the bottom section of the pivot. When the bottom section of the pivot is rotated away from the top section, a wheel connected to the prongs is offset by a distance to a side of a frame connected to the bicycle.

Abstract: A method, and apparatus for carrying it out, for processing pulses derived from a radiation detector, those pulses having already been resolved by a pulse-height analyzer into channels having respective addresses indicative of their respective heights. The method includes steps of receiving a plurality of channel-address values from the pulse-height analyzer, averaging over a window selected ones of the channel-address values to obtain an average channel address for the selected channel-address values, and using the average channel address to increment the content of a spectrum channel. Speed and accuracy of execution of the method may be optimized if a criterion for selecting channel-address values for averaging is made variable so as to permit recycling of the channel addresses and so as to avoid counting losses.

Abstract: A method, and apparatus for carrying it out, for processing pulses derived from a radiation detector, said pulses having already been resolved by a pulse-height analyzer into channels having respective addresses indicative of their respective heights, such method comprising the steps of: (a) deriving a plurality of channel address values from said pulse-height analyzer, and (b) using a plurality of said channel address values simultaneously to increment the content of a spectrum channel. In particular, a method in which said plurality of channel address values are averaged.

Abstract: In a preferred embodiment, a method of digitally de-randomizing pulses in a radiation spectroscopy system, the method including the steps of: receiving an input signal representative of a radiation detector output; analyzing the input signal to derive separate event samples and background samples; storing the event samples and the background samples; and reading stored event samples and background samples and adjusting spacing in time between adjacent event samples such that the event samples are spaced apart a time interval at least equal to pulse processing time of elements receiving an output of spaced apart event samples and the background samples.
