Apparatus and electrical circuitry are provided for electrical devices in order to provide electrical isolation of exposed electrical contacts on at least one of multiple modules of the electrical device. The apparatus includes at least one actuating component in one module and at least one sensor component within a second module in electrical communication with electrical circuitry, whereby electrical isolation of the exposed electrical contacts ceases when the sensor apparatus senses a desired location of the module. Placement of the apparatus and electrical circuitry to reside within the modules promotes electrical safety while minimizing tampering with safety aspects of the device. The apparatus and circuitry are useful for medical devices such as handheld diagnostic devices and consumer devices such as telephones.

Electrical safety system for electrical device

System and method for programming a plurality of hearing aids physically located at a plurality of remote locations, each of the plurality of hearing aids being capable of being responsive to the auditory characteristics of an individual user, being responsive to a set of auditory parameters and having a programmable memory for storing the set of auditory parameters. A first transmitting mechanism, located at each of the plurality of remote locations, transmits the auditory characteristics of those of the individual users located at one of the plurality of remote locations to a central location. A calculating mechanism, located at the central location, calculates an appropriate set of auditory parameters for each of the hearing aids based upon the auditory characteristics of each of the individual users. A second transmitting mechanism transmits the appropriate set of auditory parameters from the central location to each of the plurality of remote locations for each of the hearing aids. A storing mechanism, located at each of the plurality of remote locations, stores the appropriate auditory parameters in the programmable memory of each of the plurality of hearing aids.
