A method of using a hand-held miniature device for injecting an agent into a tree with continuous pressure that is adjustable. The device features one-thumb on/off switch operation for a metered dose, precise dose measuring, and air-powered injection in a lightweight device. The on/off switch does not need to be held in the on position by a user.

The invention provides a hand-held electronic device for injecting an agent into a tree with continuous pressure sensing technology for real-time measurements of the pressure within the tree. The pressure measurement information is conveyed to an onboard central processing unit for data collection, analysis and optimization of the speed of injecting the agent into the tree. By continually monitoring the pressure and injection power, the injection pressure can be modified to adapt to back pressure fluctuations. In one embodiment of the invention the agent is injected into the tree under a preprogrammed pressure profile. In another embodiment of the invention the agent is injected into the tree under a variable pressure profile until the fastest injection time is obtained. The invention also provides methods to identify a problem related to the health of the tree by comparing the measured pressure profile resulting from the injection of an agent into an individual tree with the typical pressure profile, stored in a database, for a tree injected under a comparable set of conditions.

A charging cradle for recharging cordless telephones which is modular and configurable in a variety of ways is provided. The cradle includes a charging unit and interchangeable telephone support structure. The charging cradle has at least two interchangeable support elements, one of which includes recharging elements. The support elements are removably attachable to support struts and may be attached in any order. The support struts are in electrical communication with the charging unit. The recharging support element includes electrical communication elements which connect the charging unit with the recharging contacts located on the external surface of the telephone handset. The charging cradle is adapted to hold the telephone handset in a nested relation while recharging the batteries located within the handset. Safety features prevent overcharging. The charging cradle may be constructed in such a manner to permit the recharging of most cordless portable telephones.
