Abstract

Disclosed is an electrical and mechanical interface to support the interconnection of a family of Personal Communicator power subsystems, such as batteries, battery chargers, tethered battery adapters, and other power sources or sinks. Devices are described as supporting plugs or receptacles, with different types of interconnections representing different functions or capabilities of a device. Both plug and receptacle types are further divided into more specific classes of products. Fulfilling electrical interface requirements assures connectivity among a variety of power subsystem elements. Within the power subsystem family, products are classified according to the type of interconnect that should be used.

Power Subsystem Interfaces for a Personal Communicator

      Disclosed is an electrical and mechanical interface to support
the interconnection of a family of Personal Communicator power
subsystems, such as batteries, battery chargers, tethered battery
adapters, and other power sources or sinks.  Devices are described as
supporting plugs or receptacles, with different types of
interconnections representing different functions or capabilities of
a device.  Both plug and receptacle types are further divided into
more specific classes of products.  Fulfilling electrical interface
requirements assures connectivity among a variety of power subsystem
elements.  Within the power subsystem family, products are classified
according to the type of interconnect that should be used.

      Sources of Personal Communicator system power, and sources of
battery charging power along with system power, form a subset of
devices having receptacles, which are connected, through mating
plugs, to devices having complementary functions.  These power source
devices are further divided into Class I devices, which are power
sources only, and Class II devices, which are chargers as well as
power sources.  An example of a Class I device is a device providing
power at a fixed voltage, such as an adapter plugging into the
cigarette lighter of a car.  An example of a Class II device is the
rapid battery charger of a portable personal communicator.

      Power transfer devices and power conversion subsystem elements
form a subset of devices having plug interconnections to be inserted
into the receptacles of the devices described above.  These devices
are also divided into Class I devices and Class II devices.  A Class
I device is for power transfer, connecting directly to a source...
