New Optical Caliper

JAPAN TAPPI JOURNAL, 2010
紙の品質管理において紙厚の精度良い測定と制御は不可欠であり，従来はこの目的のために主に両面接触式のキャリパ計が使用されてきた。しかしながら，BM計の主要センサの中で唯一接触式のセンサであり，アプリケーションによっては紙に接触することに起因する様々な課題を抱えていた。近年，BM計メーカ各社からレーザ式キャリパ計が提案されて注目を集めている。しかしながらこの方式には両面接触式とは異なる独自の問題点があり，紙厚測定・制御のソリューションとして定着するまでには至っていない。新しく開発された光学式キャリパ計は，新たな試みとしてレーザ方式ではなく共焦点技術を採用した。さらにできるだけメンテナンスフリーの状態で安定して精度良く測定できるように，様々な機能が取り込まれている ...

Complications of Skull Caliper Traction

min - Minimally Invasive Neurosurgery, 1976
During a period of 20 years 88 patients with fracture dislocation of the cervical spine were treated by attaching Crutchfield tongs to the skull. Sixty-seven per cent of all patients had some complications. The different types of complications are reported and discussed in order of frequency.

Sliding Caliper for Medicolegal Autopsies

American Journal of Clinical Pathology, 1973
A simply constructed sliding caliper has been devised for use in medicolegal autopsies. Determination of the exact locations of bullet or stab wounds above the level of the heels is helpful in establishing the angles of the paths of the missiles or weapons within the body.

A comparison of triceps skinfold values as measured by the plastic McGaw caliper and the Lange caliper

The American Journal of Clinical Nutrition, 1979
The plastic McGaw caliper and the Lange caliper were used to measure the triceps skinfold thickness of both arms of 91 volunteer subjects and of the left arms of 14 obese patients. McGaw caliper values were highly correlated with the Lange caliper values (r = 0.97) but were significantly lower than the Lange caliper values (P less than 0.01).

Database interface for digital calipers

Computer Methods and Programs in Biomedicine, 1989
With emphasis on an advanced user interface this program was designed to collect measurements from digital sliding calipers and micrometers for subsequent inclusion into a database. The original project was measurements of dental casts, but the general nature of the program makes it adaptable to fields as diverse as medicine, archaeology and industrial

A Caliper-Hook for Strabismus Surgery

Archives of Ophthalmology, 1989
An instrument to assist in resection surgery consists of a telescoping hook within a second hook that can be spread a calibrated distance. Its primary purpose is to maintain a constant tension and an accurate measure of tendon length during suture passage.
