Abstract:

A method of programming a ring oscillator for use as a temperature sensor comprises selecting an initial number of delay elements for use in a ring oscillator. The method further comprise starting a system clock counter and counting pulses of the ring oscillator until the system clock counter reaches a programmed value. The method also comprises determining whether a number of counted ring oscillator pulses is between lower and upper count thresholds and changing the number of delay elements for the ring oscillator as a result of the number of counted ring oscillator pulses being less than the lower count threshold or greater than the upper count threshold.

Abstract:

A collapsible and expandable toy container includes a base member configured for placement on a support surface, a sidewall extending upwards from the base member, a top member, and an interior space configured for holding one or more accessory items. A telescoping column supports the top member from the base member. The column is vertically extendible and retractable relative to the base member. At least one spring biases the column towards its extended position which raises the top member to access the interior space. Openable/closeable doors provides alternate access to the interior space. An optional intermediate platform may be arranged on the column between the top and base members. In the collapsed condition with doors closed, the container resembles a can and conceals any accessory items in the interior space. In the expanded condition, the container provides a multi-level play experience with play surfaces at different elevations for the child.
