1. In an apparatus for controlling temperature of infused liquids as liquid flows from a liquid-filled container through a drip chamber and tube to an entry site on a patient, wherein said drip chamber includes a transparent tube portion and is disposed along said tube subsequent said liquid-filled container, an apparatus for detecting drips within said drip chamber comprising: a housing including: an opening for receiving said drip chamber;a first housing member including an emitter disposed therein for emitting signals through said transparent tube portion in the form of non-visible light to minimize the effect of ambient visible light in the vicinity of said transparent tube portion; anda second housing member coupled to said first housing member to form said opening and including a plurality of detectors disposed therein each for detecting said non-visible light signals emitted by said emitter of said first housing member and modified by drips within said transparent tube portion to sense the presence of drips within said drip chamber, wherein each said detector includes an angular detection window providing view of an area within said transparent tube portion and detects said non-visible light signals within said view, and wherein said plurality of detectors are angularly displaced from each other about said transparent tube and are arranged to include overlapping detection windows for detecting said non-visible light signals emitted through said transparent tube portion by said emitter of said first housing member, wherein at least one angular detection window comprises a conical window. 2. The apparatus of claim 1 wherein said housing includes an exterior surface disposed along a periphery of said opening, and said detectors are disposed within said housing at said exterior surface. 3. The apparatus of claim 2 wherein said emitter is disposed at said exterior surface of said housing. 4. The apparatus of claim 1 wherein said detectors are positioned within said housing to receive said ambient visible light through said transparent tube portion without permitting said received ambient visible light to affect said drip detection. 5. The apparatus of claim 1, wherein: the emitter generates a broad signal; andthe broad signal is detectable by multiple detectors of the plurality of detectors. 6. The apparatus of claim 1, wherein the emitter generates a broad signal toward multiple detectors of the plurality of detectors. 7. In an apparatus for controlling temperature of infused liquids as liquid flows from a liquid-filled container through a drip chamber and tube to an entry site on a patient, wherein said drip chamber includes a transparent tube portion and is disposed along said tube subsequent said liquid-filled container, an apparatus for detecting drips within said drip chamber comprising: a housing including: an opening for receiving said drip chamber;a first housing member including an emitter disposed therein for emitting signals through said transparent tube portion in the form of non-visible light to minimize the effect of ambient visible light in the vicinity of said transparent tube portion; anda second housing member coupled to said first housing member to form said opening and including a plurality of detectors disposed therein each for detecting said non-visible light signals emitted by said emitter of said first housing member and modified by drips within said transparent tube portion to sense the presence of drips within said drip chamber, wherein each said detector includes an angular detection window providing view of an area within said transparent tube portion and detects said non-visible light signals within said view, and wherein said plurality of detectors are angularly displaced from each other about said transparent tube and are arranged to include overlapping detection windows for detecting said non-visible light signals emitted through said transparent tube portion by said emitter of said first housing member, wherein the emitter generates a conical signal. 8. The apparatus of claim 7, wherein the signal is a 50° conical signal. 9. In an apparatus for controlling temperature of infused liquids as liquid flows from a liquid-filled container through a drip chamber and tube to an entry site on a patient, wherein said drip chamber includes a transparent tube portion and is disposed along said tube subsequent said liquid-filled container, and said apparatus includes a drip detector having a housing including an opening, a method for detecting drips within said drip chamber comprising: (a) receiving said drip chamber through said opening of said housing, wherein said housing includes first and second housing members coupled together to form said opening;(b) emitting signals through said transparent tube portion in the form of non-visible light, via an emitter disposed within said first housing member, to minimize the effect of ambient visible light in the vicinity of said transparent tube portion; and(c) detecting said non-visible light signals emitted by said emitter of said first housing member and modified by drips within said transparent tube portion, via a plurality of detectors disposed within said second housing member, to sense the presence of drips within said drip chamber, wherein each said detector includes an angular detection window providing view of an area within said transparent tube portion and detects said non-visible light signals within said view, and wherein said plurality of detectors are angularly displaced from each other about said transparent tube and arranged to include overlapping detection windows for detecting said non-visible light signals emitted through said transparent tube portion by said emitter of said first housing member, wherein at least one angular detection window comprises a conical window. 10. The method of claim 9 wherein: said housing includes an exterior surface disposed along a periphery of said opening, andstep (c) further includes: (c.1) positioning said detectors within said housing at said exterior surface. 11. The method of claim 10 wherein step (c) further includes: (c.2) disposing said emitter at said exterior surface of said housing. 12. The method of claim 9 wherein step (c) further includes: (c.1) positioning said detectors within said housing to receive said ambient visible light through said transparent tube portion without permitting said received ambient visible light to affect said drip detection. 13. The method of claim 9, wherein (b) further comprises (b.1) emitting a broad signal detectable by multiple detectors. 14. The method of claim 9, wherein (b) further comprises (b.1.) emitting a signal toward multiple detectors of the plurality of detectors. 15. In an apparatus for controlling temperature of infused liquids as liquid flows from a liquid-filled container through a drip chamber and tube to an entry site on a patient, wherein said drip chamber includes a transparent tube portion and is disposed along said tube subsequent said liquid-filled container, and said apparatus includes a drip detector having a housing including an opening, a method for detecting drips within said drip chamber comprising: (a) receiving said drip chamber through said opening of said housing, wherein said housing includes first and second housing members coupled together to form said opening;(b) emitting signals through said transparent tube portion in the form of non-visible light, via an emitter disposed within said first housing member, to minimize the effect of ambient visible light in the vicinity of said transparent tube portion; and(c) detecting said non-visible light signals emitted by said emitter of said first housing member and modified by drips within said transparent tube portion, via a plurality of detectors disposed within said second housing member, to sense the presence of drips within said drip chamber, wherein each said detector includes an angular detection window providing view of an area within said transparent tube portion and detects said non-visible light signals within said view, and wherein said plurality of detectors are angularly displaced from each other about said transparent tube and arranged to include overlapping detection windows for detecting said non-visible light signals emitted through said transparent tube portion by said emitter of said first housing member, wherein: the signal is conical; and (b) comprises (b.1) emitting a conical signal toward the plurality of detectors. 16. The method of claim 15, wherein the signal is a 50° conical signal.
