Visual Biases Near Hand-held and Remotely Controlled Tools

Operating hand-held vibrating tools and prevalence of white fingers.

Hand-transmitted vibration levels (HTVLs) and the prevalence of vibration-induced white finger (VWF) and numbness of the hands were investigated in eight groups of subjects operating various hand-held vibrating tools. The prevalence rates of Raynaud's phenomenon (RP) and numbness of the hands in 1,027 males and 1,301 females not occupationally exposed to vibration were compared to those of the ...

The Performance Leader in Hand-Held Network Tools

Near-infrared-actuated devices for remotely controlled drug delivery.

A reservoir that could be remotely triggered to release a drug would enable the patient or physician to achieve on-demand, reproducible, repeated, and tunable dosing. Such a device would allow precise adjustment of dosage to desired effect, with a consequent minimization of toxicity, and could obviate repeated drug administrations or device implantations, enhancing patient compliance. It should...

Hand-Held Magnetoresistive Transducer

The initial design of a vertical magnetoresistive head in a hand-held wand for reading magnetically encoded price tags and credit cards is discussed. The performance of the head (e.g., resolution, signal shape and amplitude, and signal-to-noise ratio) is analytically and experimentally evaluated as a function of the configuration of the sensor, head-to-medium interface, and sensor processing an...

Hand-held myometry.

In their two recent articles, Vander Ploeg et al provided information that should prove useful to clinicians who use hand held dynamometers. The reference values presented by the authors provide a much needed basis for establishing the normality of a patient's strength.' The ratios between the forces measured during make tests and break tests may, as the authors suggest, be diagnostically discr...
