Apple patent is for wireless headset featuring adaptive powering

An Apple patent (number 8185084) for a wireless headset featuring adaptive powering has appeared at the U.S. Patent & Trademark Office.

A system that includes a bus, a battery, core processing circuitry, radio frequency (RF) processing circuitry, first power regulating circuitry, second power regulating circuitry, and control circuitry is provided. The bus can be coupled to receive power from a source external to the system. The core processing circuitry and RF processing circuitry can be selectively coupled to each other via a switch. The switch can be operative to turn ON and OFF based on a signal level received on the bus.

The first power regulating circuitry can be electrically coupled to the bus, the core processing circuitry, and the switch. The second power regulating circuitry can be electrically coupled to the battery, the RF processing circuitry, and the switch. The control circuitry can be operative to selectively turn ON and OFF the first power regulating circuitry and the second power regulating circuitry based on a number of monitored conditions.

Here's Apple's background on the invention: "Headsets for providing hands-free communications are known in the art. Such headsets typically can be used in conjunction with a cellular telephone or a computer (e.g., Voice over IP). Some existing headsets include a microphone, a speaker (also referred to as a receiver), electronics for controlling the headset and communicating with another device (e.g., a cellular telephone), a battery and a connector for re-charging the battery.

There are many aspects involved in the design of headsets. For example, the size and weight of headsets can be key issues because of how they typically mount to a user's ear. A heavy or large headset can pull on a user's ear, creating an uncomfortable fit. The shape of headset earpieces (e.g., earbuds) may also be an important design consideration to take into account as it is desirable for earpieces to fit comfortably in, on, or over a wide range of different sizes and shapes of ears.

Additionally, the acoustic performance of headsets, such as receiver sound generation quality and microphone sound reception quality (e.g., ability to pick up a user's voice without undue background noise), can be important design considerations. Achieving desired receiver and microphone acoustic performance can become increasingly difficult as the size of a headset decreases.

Another example of an important design consideration can be the user interface of a headset. It may be desirable for a user interface to be intuitive for a first-time user, yet convenient for an experienced user. Aesthetics may be yet another important design consideration for headsets.

Further still, ease of manufacturing headsets can be another design consideration. For example, it can be desirable to design a headset that can be mass produced in an affordable fashion. In view of the foregoing, there is a need for an improved headset that addresses one or more of the above-identified considerations."

Jeffrey J. Terlizzi is the inventor.
