Digital-output cardiotachometer measures rapid changes in heartbeat rate

Cardiotachometer circuits produce an output voltage proportional to the heartbeat rate on a beat-by-beat basis. This is less complex and less costly than the digital cardiotachometers

Inexpensive, stable circuit measures heart rate

Inexpensive transistorized circuit provides reliable analog indications of heart rate in response to preamplified electrocardiograph signal applied to its input

Biomedical recording system

System collects medical data directly from patients and permanently records and displays several parameters - electrocardiograph, electroencephalograph, heart rate, respiration rate, auscultatory blood pressure, leg circumference changes, body temperature, and time. Components and operation of the system are described

Blood pressure measuring system for separating and separately recording dc signal and an ac signal Patent

Blood pressure measuring system for separately recording dc and ac pressure signals of Korotkoff sound

Direct Payments, Independent Living and Mental Health

This report is based on a study of the National Pilot to implement direct payments in mental health which took place across five Local Authority sites in England from February 2001 to July 2003. The evaluation used the experiences of the pilot sites as a vehicle through which to understand the factors involved in successfully implementing direct payments in mental health. The evaluation took place in 2002-2003 during the last year of the pilot. This chapter provides an overview of the direct payments and mental health literature and outlines the background to both the National Pilot and the evaluation

Higher-dimensional linking integrals

We derive an integral formula for the linking number of two submanifolds of the n-sphere S^n, of the product S^n x R^m, and of other manifolds which appear as "nice" hypersurfaces in Euclidean space. The formulas are geometrically meaningful in that they are invariant under the action of the special orthogonal group on the ambient space.Comment: 10 pages, 3 figure

Legendrian contact homology and nondestabilizability

We provide the first example of a Legendrian knot with nonvanishing contact homology whose Thurston-Bennequin invariant is not maximal.Comment: 12 pages, 2 figure
