The One Who Held Her Hand

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...

Hand-held myometry: reference values.

In thirteen major muscle groups of 50 healthy females and 50 males, aged 20-60 years, maximum voluntary contraction was measured with a hand-held dynamometer. The intrasession variation, the left-right variation, and the fifth and fiftieth centile values were calculated. The ratio of two observations within one session ranged from 0.85 to 1.18 and the ratio of left to right ranged from 0.82 to ...

The Hand-Held Force Magnifier & One-Dimensional Haptic Rendering Using an Audio Speaker

The following work deals with the haptic problem, which resulting from the loss of tactile sense during delicate microsurgeries. One of the developments that solve this problem is the Hand-Held Force Magnifier (HHFM). The research presents a conceptual design of a quick change of tools to the HHFM third prototype and a development of a new prototype, the HHFM-4. The fourth HHFM prototype will r...
