Abstract: A portable electroplating system with components integrated into a complete system, rather than separated and disjointed. A single electroplating system can be self-contained to include all necessary rectifiers, tanks, cleaning functionalities, and other helpful or necessary items. By using smaller components than conventional electroplating systems, the system can allow for more economical use of chemicals, solutions, and energy and can be utilized more efficiently towards a unique shape or size of object to be plated. The system can also include wheels to make the system portable. A rack management system can be employed to move objects from one location to another within the system.

Abstract: A rechargeable power pack comprises a housing, an energy storage device received in the housing, and a set of contacts extending from the housing and electrically coupled to the energy storage device to provide an electrical input current to the energy storage device at a first time and an electrical output current from the energy storage device at a second time. The electrical contacts are preferably formed as a set of prongs sized and dimensioned to be received in a standard electrical outlet. The rechargeable power pack may contain a charging circuit, a discharging circuit, and a switch to selectively couple the charging circuit and the discharging circuit between the contacts and the energy storage device. Additional circuitry may be provided for decoupling the charging circuit when either a voltage, temperature, or time has exceeded some predefined value.

Abstract: Disclosed is a system for rapid, wireless communication of electrically-generated and detected, serial digital data signals via a plurality of infrared (or other compatible wireless medium) transceivers. Signals are communicated without electrical connection among computers, fax machines, computer peripheral equipment, or may be employed within self-contained communication, control data-acquisition, and/or display systems. The system operates at predetermined maximum data rates and sub-multiples thereof. The disclosed transceivers can be joined with additional circuits, to form an arrangement that operates as a wireless modem. In each arrangement, light is continuously modulated at either of two precise multiples of the predetermined maximum data rate, and is synchronized to transmitted-data transitions. Upon receipt of light-signals thus produced, the system's receiving transceiver synchronizes received-data electrical output signals to the received modulated light signals.
