A power dongle for a hearing aid includes conductive wires, each wire having a computing device end and a hearing aid end. A first connector is connected to the computing device end of each of the plurality of conductive wires to releasably couple to an input/output port of the computing device and a second connector is connected to the hearing aid end of each of the plurality of conductive wires to releasably couple to an interface of the hearing aid, the second connector configured to deliver at least one of a first power supply and an audio signal from the computing device to the interface of the hearing aid.

Hearing aid and hearing aid dual use dongle

A hearing aid includes a microphone to convert sounds into electrical signals, a transceiver configured to communicate with a computing device through a wireless communication channel, and a processor coupled to the microphone and the transceiver. The hearing aid further includes a memory accessible to the processor and configured to store a table including plurality of hearing aid profile identifiers (IDs). Each of the plurality of hearing aid profile IDs corresponds to a respective one of a plurality of hearing aid profiles. The memory stores instructions that, when executed by the processor cause the processor to identify a hearing aid profile ID from the table based on a sound sample, retrieve a hearing aid profile from the computing device using the hearing aid profile ID, and apply the hearing aid profile to modulate an audio output signal.

Hearing aid, computing device, and method for selecting a hearing aid profile

An apparatus for measuring electrical characteristics of solar panels (photovoltaic modules) wherein the apparatus measures current versus voltage ('I-V') relationships for both illuminated ('light I-V') and/or non-illuminated (&#x201c;dark I-V&#x201d;) conditions; optionally provides single, dual, or four-quadrant source/sink capability; and measures one or more devices under test (DUTs). The apparatus comprises one or more source measurement units (SMUs), wherein each SMU is connected to one DUT, and optionally includes a positive high-voltage programmable power supply and/or a negative high-voltage programmable power supply. Additionally, the apparatus includes a controller which controls the functions of the SMUs, the high-voltage supplies, and other components of the apparatus, wherein the controller communicates with the SMUs over a signal bus. Finally, the apparatus may include a computer to provide a user interface, communicate with the controller to initiate measurements and record results, analyze resulting data to determine measured parameters, and/or store the measured data.
