1.2013年3月12日に米国特許出願第13/796,889号として提出され、2014年8月26日に発行された、「投与量測定システム及び方法」と題された米国特許第8,817,258号;
2.2014年7月17に提出された、「投与量測定システム及び方法」と題された米国特許出願第14/334,181号;
3.2014年8月1日に提出された、「温度センサを備えた液体測定システム」と題された米国特許出願第62/032,017号;及び
4.2014年11月20日に提出された、「投与量測定システム及び方法」と題された米国特許出願第14/548,679号
A×ΔT×Sraw (1)
ただし、Aは個々のセンサ設計によって変化し得るスケーリング係数、Srawは未処理のセンサ読み取り値、及びΔTは測定された温度とベースライン温度との間の差であり、これは一定である限りは任意の温度(例えば0℃)であり得る。
ΔT=Tmeas-Tbase (2)
よって、補償されたセンサ値は、
Scomp=Sraw+A×ΔT×Sraw (3)
によって決定され得る。
本明細書においては本発明の様々な実施形態が記載され説明されてきたが、当該技術分野における通常の技能を有する者は、本明細書に記載された機能を実施するため、ならびに/あるいは、結果及び/又は1つ以上の利点を得るための、様々な他の手段及び/又は構造を容易に想像するであろうし、そのような変形及び/又は変更の各々は、本明細書に記載された本発明の実施形態の範囲内にあるものと見なされる。より一般的には、当業者は、本明細書に記載されたすべてのパラメータ、寸法、材料、及び構成は例示的であることを意図されていること、及び実際のパラメータ、寸法、材料、及び/又は構成は本発明の教示が用いられる具体的な用途に依存するであろうことを容易に察知するであろう。当業者は、単に型通りの実験を用いるだけで、本明細書に記載された具体的な本発明の実施形態と均等な多くの実施形態を認識するか、又は確認できるであろう。したがって、前述の実施形態は例として提示されているに過ぎないこと、そして、本発明の実施形態は、具体的に記載され特許を請求されている以外に、添付の特許請求の範囲及びその均等物の範囲内で実施され得ることが理解されるべきである。本開示における本発明の実施形態は、本明細書に記載された個々の特徴、システム、部品、材料、キット、及び/又は方法を対象とするものである。また、2つ以上のそのような特徴、システム、部品、材料、キット、及び/又は方法の任意の組み合わせは、そのような特徴、システム、部品、材料、キット、及び/又は方法が相互に矛盾しない場合には、本開示における本発明の範囲内に含まれる。
