Androgenic steroids are drugs that resemble androgenic hormones such as testosterone. Androgenic refers to increased masculine characteristics. These are widely used by athletes involved in such sports as track and weight lifting.

An Anechoic Chamber is a shielded room designed to attenuate waves. Anechoic chambers are used to provide a shielded environment for radio frequency (RF) and microwaves. An RF anechoic chamber is designed to suppress the electromagnetic wave analogy of echoes, reflected electromagnetic waves, from the internal surfaces. Both types of chambers are constructed with echo suppression features and with effective isolation from the acoustic or RF noise present in the external environment. In a well-designed acoustic or RF anechoic chamber, the equipment under test receive acoustic, mechanical or RF signals from the signal source, not reflected from another part of the chamber. This ensures the integrity of the testing being conducted. Furthermore, the shielding of the chamber limits interference from equipment located outside of the chamber.

The aneroid sphygmomanometer is a rugged, reliable handheld cuff inflator used for manual inflation of vascular cuffs. They pump fast and is symmetrical for easy operation with either hand. Precise deflation control is achieved with a trigger-type valve. It can also be used with segmental cuff selector.

Anesthesia delivery unit is a pioneering approach to anesthesia delivery. It is designed to mix and dose respiratory gases and to ventilate the patient. The delivery unit is the basis for a flexible anesthesia system with full monitoring and data management capabilities.
