  • Meter cradle with wireless communication port
    Patent number: 5640155
    Abstract: A cradle apparatus (18 or 42) including a wireless interface for communicating via signal-transporting radiation (such as infrared radiation modulated so as to transmit data and control signals) with one or more meters (12) such as portable, hand-holdable, battery-powered multimeters, or other portable meters, mounted to the cradle apparatus, and a meter (12) which transmits signal-transporting radiation to the wireless interface when the meter is removably mounted to the cradle. Some embodiments, include a cradle having a wireless interface, a meter which transmits signal-transporting radiation to the wireless interface when the meter is removably mounted to the cradle, and a processor (48) for receiving from the cradle electrical signals indicative of data transmitted from the meter. Optionally, the wireless interface of the cradle also supplies visible radiation to a meter mounted to the cradle, for illuminating a display (14) of the meter.
