Abstract: A frequency linearity measurement circuit configured to measure a frequency linearity of a frequency signal includes: a first measurement circuit having a counter, where the counter is controlled by a gate signal having a gate signal period, where the first measurement circuit is configured to generate a first estimate of an integer number of clock cycles of the frequency signal within a respective gate signal period of the gate signal; a second measurement circuit having a time-to-digital converter (TDC), where the TDC is controlled by the gate signal, and is configured to generate a second estimate of a fractional number of clock cycle of the frequency signal within the respective gate signal period of the gate signal; and a reference measurement circuit configured to generate a third estimate of an expected number of clock cycles within the respective gate signal period of the gate signal.

Abstract: A frequency linearity measurement circuit configured to measure a frequency linearity of a frequency signal includes: a first measurement circuit configured to generate a first estimate of an integer number of clock cycles of the frequency signal within a respective gate signal period of a gate signal; a second measurement circuit comprising a time-to-digital converter (TDC) configured to generate a second estimate of a fractional number of clock cycle of the frequency signal within the respective gate signal period; a reference measurement circuit configured to generate a third estimate of an expected number of clock cycles within the respective gate signal period; and a closed-loop frequency tracking circuit configured to track a frequency error between an expected frequency and a measured frequency, where the expected frequency and the measured frequency are determined based on the third estimate and on a sum of the first estimate and the second estimate, respectively.

Abstract: An array of feeding implement products including a first feeding implement adapted for use during a first stage of development, a first package enclosing the first feeding implement, and a first pictorial representation disposed on the first package. The first pictorial representation depicts the first feeding implement, a caregiver, and a first baby, wherein the first baby is represented as corresponding to the first stage of development. The array further includes a second feeding implement adapted for use during a second stage of development, a second package enclosing the second feeding implement, and a second pictorial representation disposed on the second package. The second pictorial representation depicts the second feeding implement, a caregiver, and a second baby, wherein the second baby is represented as corresponding to the second stage of development.

Abstract: A marking system for assisting identification of baby care articles appropriate for a particular baby includes an array of pictorial representations including at least a first set of pictorial representations corresponding to a first stage of development and a second set of pictorial representations corresponding to a second stage of development. A first set of baby care articles adapted for use during the first stage of development is provided, wherein the first set of baby care articles includes baby care articles from at least two different baby care article sub-sets selected from the group of baby care article sub-sets comprising diapers, wipes, bibs, feeding implements, bath care items, and personal hygiene products. Each baby care article in the first set of baby care articles bears a pictorial representation selected from the first set of pictorial representations.

Abstract: A retail display for baby care articles includes a first display section associated with a first set of baby care articles adapted for use during a first stage of development. The first set of baby care articles includes baby care articles from at least two different baby care article sub-sets selected from the group of baby care article sub-sets comprising diapers, wipes, bibs, feeding implements, bath care items, and personal hygiene products. The display further includes a second display section associated with a second set of baby care articles adapted for use during a second stage of development. The second set of baby care articles includes baby care articles from at least two different baby care article sub-sets selected from a group of baby care article sub-sets comprising diapers, wipes, bibs, feeding implements, bath care items, and personal hygiene products.
