Jeroen Thijssen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7917172
    Abstract: The invention relates to an accessory (18) for connection to an electrical interface (16) of a portable electronic device (10), which interface comprises a pair of bias voltage providing connection points including a first connection point (42) and a second connection point (44) for biasing a signal providing element (22) that may be provided in the accessory. The accessory includes a first electrical branch comprising a first voltage dividing element (R1) and a first switch (32) that can be actuated mechanically. The branch has a first end to be connected to one connection point (42) in the pair and a second end to be connected to another connection point (46) for changing the voltage level of the connection point connected to the first end to a certain voltage level when the first switch interconnects the first voltage dividing element and this connection point.

  • Patent number: 7701168
    Abstract: A device may include a first connector configured to connect to a portable device and a second connector configured to connect to a power source. The device may also include circuitry configured to provide a first charging current to the portable device via the first connector when the second connector is connected to a power adapter coupled to a power outlet and provide a second charging current to the portable device via the first connector when the second connector is connected to a universal serial bus port of a host device.

  • Patent number: 7643850
    Abstract: A cellular communication terminal is configured to function as a mouse for a proximately located computer. The cellular communication terminal includes a cellular transceiver, a communication interface, an accelerometer, and a controller. The cellular transceiver is configured to communicate over a wireless cellular interface with a cellular network. The communication interface is configured to be communicatively coupled to the proximately located computer. The accelerometer is configured to generate acceleration information that is indicative of movement of the terminal.

  • Patent number: 7565458
    Abstract: In some embodiments, a method is provided for identifying a communication interface of an electronic unit attached to a connector of an electronic device. A voltage pulse is generated in the device on a pin of the connector. The voltage on the pin is measured, as it is affected by a load in the unit. The measured voltage is compared with predetermined voltage criteria. Communication interface identification is performed on the unit dependent on the comparison.
