Abstract

In many situations, an audible alert from a port- able device is undesirable. In high noise environ- ments the audible alert may go unnoticed, and in low noise environments the alert may be disruptive. Additionally, audible alerts afford little privacy to the user, who may wish to be alerted without the knowledge of others.

"INTEGRATION OF TACTILE ANNUNCIATOR AND BATTERY"

by Ellis A. Pinder and Michael M. Austin

  In many situations, an audible alert from a port- able device is undesirable. In high noise environ- ments the audible alert may go unnoticed, and in low noise environments the alert may be disruptive. Additionally, audible alerts afford little privacy to the user, who may wish to be alerted without the knowledge of others.

  One possible solution to this problem is to silently alert the user by using a specially-designed battery pack with a tactile annunciator. A tactile annuncia- tor is a triggerable transducer which produces phys- ical movement felt by the user. A common example of a tactile annunciator used in many pagers and cellular phones is a small motor with an attached cam. Since the battery packs ofmany portable prod- ucts are in direct physical contact with the user's body, such an assembly produces a noticeable shak- ing effect when activated.

  Integrating the tactile annunciator with a bat- tery is a more desirable approach than placing the annunciator in the portable host device itself In the latter case, users not wanting the feature would suf- fer size, weight, and cost penalties. By integrating the battery with the annunciator, this special bat- tery pack becomes an accessory that may be added by the user at any time.

The annunciator itself is contained inside the

battery pack, along with one or more cells, as illus- trated in the diagram. The annunciator may be fixed inside t...
