Ergonomic Design of Magic Saw Handle

Ergonomic redesign and evaluation of a clamping tool handle.

The handle of a commercial bar clamp was redesigned using ergonomic principles and then compared with an original clamp. Ten male and ten female students participated in simulated clamping tasks under various conditions, including different clamping heights, clamping methods, and handle-gripping methods, with respect to the dependent variables of clamping and handle-squeezing forces. The result...

Ergonomic T-Handle for Minimally Invasive Surgical Instruments

A T-handle has been designed to be used for minimally invasive implantation of a dynamic hip screw to repair fractures of the proximal femur. It is capable of being used in two actions: (i) push and hold (while using an angle guide) and (ii) application of torque when using the insertion wrench and lag screw tap. The T-handle can be held in a power or precision grip. It is suitable for either s...

Design of Global Saw Rfid Tag Devices

The Global SAW Tag [1] is projected to be a large-volume SAW device application. The modulation method and overall tag data structure are reviewed for a family of proposed RFID devices. Current implementations use a basic group structure that encodes 16 information bits using 4 reflectors chosen from 75 reflector slots. Several groups are placed in-line on a single acoustic track to achieve ID ...
