Polarity control for a flat connector
First Claim
Patent Images
1. An electronic device comprising:
- a port engageable with a flat connector in any of plural orientations of the flat connector, the port comprising a power contact and data contacts, the power contact to engage a respective contact of the flat connector when the port and the flat connector are engaged; and
a switching circuit comprising switches to;
receive input signals from the data contacts of the port when the port is engaged with the flat connector, wherein the switches are controllable by an input power signal from the power contact of the port when the port and the flat connector are engaged, andapply 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 the power contact of the port.

Abstract
In some examples, a sink device includes a port comprising a power contact and data contacts, the port having a profile to engage with a flat connector in any of plural orientations of the flat connector, where the data contacts are to electrically connect to data contacts of the flat connector. A switching circuit comprises switches 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.

11. A sink device comprising:
-
a port comprising a power contact and data contacts, the port having a profile to engage with a flat connector in any of plural orientations of the flat connector, wherein the data contacts are to electrically connect to data contacts of the flat connector; a switching circuit comprising switches to apply polarity processing to signals corresponding to the data contacts of the port to produce output data signals at a target data polarity regardless of the orientation of the flat connector when connected to the port, wherein the switches are to selectively connect the output data signals to the signals corresponding to the data contacts of the port in a first arrangement in response to detecting a first orientation of the flat connector, and to connect the output data signals to the signals corresponding to the data contacts of the port in a second, different arrangement in response to detecting a second, different orientation of the flat connector, and wherein the switches are controllable by a signal from the power contact of the port. - View Dependent Claims (12, 13)

14. A system comprising:
-
a power adapter comprising a flat connector including a power 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; and switches controllable by an input power signal, the input power signal having a first state when the port is engaged with the flat connector in a first orientation, the input power signal having the first state to set the switches to first positions, the input power signal having a second state when the port is engaged with the flat connector in a second orientation, the input power signal having the second state 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 (15, 16, 17)
