Abstract: Methods, systems, and apparatuses for booting an accessory with an accessory firmware image received from a host device are described. When the host device detects a connection between the accessory and the host device, the host device may send a request for an accessory identifier to the accessory. The accessory may send an accessory identifier to the host device in response. The host device may select an accessory firmware image that is suitable for the accessory, and may transmit the accessory firmware image to the accessory. The accessory firmware image may include information that the accessory can use to enable the accessory to exchange application data with the host device. Fig. 1A Fig. 1EB

Abstract: An alternating current (AC) to direct current (DC) power converter may have a connector with a pair of power supply contacts and a pair of data contacts. An electronic device may be connected to the connector of the power converter. The power converter may supply DC power to the electronic device using the power supply contacts. The power converter may include control circuitry that has a resistor coupled across the data contacts. When the electronic device and the power converter are connected to each other, each may advertize to the other that capabilities are present that exceed industry standards. At the same time, standard-compliant discovery operations may be performed to probe the value of the resistance of the resistor that is coupled across the data contacts. When extended capabilities are discovered, extended functions may be performed including accelerated charging functions and data communications functions.

Abstract: Methods, systems, and apparatus for determining whether an accessory includes particular circuitry. A host device may measure a first voltage and a second voltage received from an accessory, where the voltages are provide through the accessory from a power source. Before measuring the second voltage, the host device may send an instruction to the accessory instructing the accessory to alter an impedance of the power path between the power source and the host device, and the host device may draw at least a threshold amount of current from the power source via the accessory. The host device may then determine whether the accessory includes particular circuitry based on the relationship between the first voltage and the second voltage.

Abstract: Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device 5 based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.

Abstract: Computerlesbare Speichermedien, elektronische Vorrichtungen und Zubehörteile mit darin gespeicherten Datenstrukturen. Eine Datenstruktur weist ein Stiftauswahlfeld auf, welches wirksam ist, um einen Steckverbinderstift zu identifizieren, und eine elektronische Vorrichtung dazu zu bringen, eines aus einer Vielzahl von Kommunikationsprotokollen zum Kommunizieren mit einem Zubehörteil über den identifizierten Steckverbinderstift auszuwählen. Die Datenstruktur weist auch ein Zubehörteilfähigkeitsfeld auf, welches einen Zubehörtei identifizierer definiert, welcher das Zubehörteil eindeutig identifiziert.

Abstract: Methods, systems, and apparatus for enabling a power path between a power source and a host device via an accessory. A host device may send, to an accessory arranged within the power path, via a first data pin arranged in the host device, a request for an accessory identifier. The accessory identifier identifies the accessory. The host device may then determine whether the accessory identifier is received from the accessory within a specified period of time or whether a received accessory identifier is valid. If the accessory identifier is not received from the accessory within the specified period of time, or a received accessory identifier is not valid, the host device sends a new request for the accessory identifier to the accessory via a second data pin different than the first data pin.

Abstract: Verfahren, Systeme und Vorrichtungen zum Einrichten eines Leistungspfades zwischen einer Leistungsquelle und einer Hostvorrichtung über ein Zubehör. Eine Hostvorrichtung kann eine Anfrage für einen Zubehöridentifikator an ein Zubehör, das innerhalb eines Leistungspfades angeordnet ist, über einen ersten Datenpin, der innerhalb der Hostvorrichtung angeordnet ist, senden. Der Zubehöridentifikator identifiziert das Zubehör. Die Hostvorrichtung kann dann feststellen, ob der Zubehöridentifikator innerhalb einer bestimmten Zeitspanne von dem Zubehör empfangen worden ist oder, ob ein empfangener Zubehöridentifikator gültig ist. Wenn der Zubehöridentifikator von dem Zubehör nicht innerhalb der bestimmten Zeitspanne empfangen worden ist oder, wenn ein empfangener Zubehöridentifikator nicht gültig ist, sendet die Hostvorrichtung eine neue Anfrage für den Zubehöridentifikator an das Zubehör über einen zweiten Datenpin, der anders ist als der erste Datenpin.

Abstract: Systems and methods for configuring contacts of a first connector includes detecting mating of a second connector with the first connector and in response to the detection, sending a command over one of the contacts and waiting for 5 a response to the command. If a valid response to the command is received, the system determines the orientation of the second connector. The response also includes configuration information for contacts in the second connector. The system then configures some of the other contacts of the first connector based on the determined orientation and configuration information of the contacts of the second 10 connector.
