Patent Images
1. A sink device, comprising:
- a port comprising a profile to engage with a flat connector including a power contact and a reference contact, wherein the port is engageable with the flat connector in any of plural orientations of the flat connector, wherein the port has a plurality of contacts, the plurality of contacts to;
electrically connect to the power contact and reference contact of the flat connector; and
electrically connect to data contacts of the flat connector;
a polarity control circuit connected to the port to apply polarity processing to signals corresponding to the power and reference contacts to produce output power signals at a target polarity regardless of an orientation of the flat connector when connected to the port; and
a switching circuit to apply polarity processing to signals corresponding to the data contacts to produce output data signals at a target data polarity regardless of the orientation of the flat connector when connected to the port.

Abstract
A polarity control circuit receives signals from contacts of a flat connector when the flat connector is connected to a port, where the port is engageable with the flat connector in any of plural orientations of the flat connector. The polarity control circuit applies polarity processing to the input signals to produce output signals at a target polarity.

9. A system comprising:
-
a power adaptor comprising a flat connector including a power contact, a reference contact, a positive data contact, and a negative data contact; a sink device comprising a port engageable with the flat connector in any of plural orientations of the flat connector; a polarity control circuit comprising a rectifier to receive input power signals connected to the power contact and the reference contact of the flat connector, the rectifier to apply rectification to the input power signals to produce output power signals at a target power polarity; and switches controllable by a first input power signal of the input power signals, the first input power signal when connected to the power contact to set the switches to first positions, and the first input power signal when connected to the reference contact to set the switches to second positions different from the first positions, the switches to receive input data signals connected to the positive and negative data contacts, the switches to provide output data signals at a target data polarity regardless of an orientation of the flat connector when engaged with the port of the sink device. - View Dependent Claims (10, 11)

15. A method comprising:
-
receiving, by a switching circuit, input signals from port contacts of a port when the port is engaged with a flat connector, wherein the port is engageable with the flat connector in any of plural orientations of the flat connector; and applying, by the switching circuit, polarity processing to the input signals to produce output data signals at a target polarity regardless of the orientation of the flat connector when engaged to the port, wherein the polarity processing is based on detecting a state of a power-related contact of the flat connector, the switching circuit comprising switches that are controllable by an input power signal connected to the power-related contact of the flat connector. - View Dependent Claims (16, 17)
