Mobile charging unit for input devices
First Claim
1. A mobile charging apparatus comprising:
- a sleeve portion adapted to receive an input device via a first opening at a first end of the sleeve portion, the sleeve portion having a second end presenting a second opening; and
a base portion having a sleeve coupling end adapted for removable coupling to the second end of the sleeve portion, the second opening of the second end being configured to accommodate the sleeve coupling end when the base portion and sleeve portion are in a coupled configuration, the cavity comprising charging contacts coupled to a first rechargeable battery that is disposed within the base portion, the base portion being configured to;
receive electrical power from an external power source to recharge the first rechargeable battery via an interface configured on the base portion; and
charge a second rechargeable battery of the input device when the input device is removably secured to the cavity by transferring electrical power received from the external power source via an electrical connection between the charging contacts and charging zones of a conductive surface of the input device.

Abstract
Devices, methods, and systems for charging input devices. A charging unit includes a sleeve for receiving a stylus and a base. The charging unit receives electrical power from an external power source via an interface and transfers the power to the stylus via a connection between the base'"'"'s charging contacts and conductive charging zones on a portion of the input device in the base. A method detects insertion of a stylus into a charging unit having an internal battery and an interface capable of receiving power from an external power source. The method determines if the unit is connected to a power source. If so, the stylus is charged by transferring the received energy via a connection between the unit'"'"'s charging contacts and conductive charging zones of the stylus. If energy is not being received from the external power source, the method charges the stylus using the unit'"'"'s internal battery.

12. A method for charging a rechargeable stylus, the method comprising:
-
detecting insertion of a stylus into a housing of a charging unit, the housing comprising a protective sleeve adapted to receive the stylus through a first open end, and a charging base portion having a protective sleeve coupling end for removable coupling to a second open end of the protective sleeve, the charging base portion having a first rechargeable battery and an interface configured to receive electrical power from an external power source, the housing being adapted to protect a body and a tip of the inserted stylus from external mechanical forces when the protective sleeve and the charging base portion are in a coupled configuration; determining whether the charging unit is coupled to the external power source; in response to determining that the charging unit is not coupled to the external power source, charging the second rechargeable battery of the inserted stylus utilizing the first rechargeable battery of the charging unit. - View Dependent Claims (13)

14. A system for charging a stylus, the system comprising:
-
an external power source adapted to transmit electrical power via an interface; and a charging unit comprising; an elongate housing having a body portion and a base portion adapted to be removably coupled to the body portion, wherein at least the base portion presents an opening adapted to receive the stylus when the base portion and the body portion are in a decoupled configuration, the body portion and the base portion being adapted to encase a body and a tip of the received stylus for protection from external mechanical forces when in a coupled configuration, a mechanical coupling mechanism adapted to secure the received stylus within the elongate housing, charging contacts adapted to transfer electrical current via an electrical connection from one of a first rechargeable battery of the charging unit and the power source to charging zones of a conductive surface of the secured stylus; wherein the charging unit is configured to; detect the stylus received via the opening, receive electrical power from the external power source via the interface; and charge a second rechargeable battery of the secured stylus by transferring electrical power received from the external power source to the second rechargeable battery via an electrical connection between the charging contacts and the charging zones. - View Dependent Claims (18, 19)
