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
