Publication number: 20240106230Abstract: Systems, methods, and apparatuses can detect whether an electrical cable between a source device and a sink device has become disconnected. The source device and/or the sink device can be compliant with a version of a Universal Serial Bus (USB) standard, for example, USB 3.x. These systems, methods, and apparatuses can monitor peak voltage swings of data signals flowing between the source device and the sink device. The peak voltage swing of these data signals can be at a first value when the electrical cable is connected to the source device and the sink device or at a second value greater than the first value when the electrical cable is disconnected from the source device or the sink device. The peak voltage swing can switch from the first value to the second value in response to the electrical cable being disconnected from the source device or the sink device.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Applicant: Apple Inc.Inventor: Christine M.

Patent number: 9787264Abstract: Techniques and mechanisms for providing signal communication with a configurable transceiver circuit. In an embodiment, an integrated circuit comprises transceiver circuitry including an output stage and current mirror circuitry. The output stage is coupled to receive a differential signal pair and to provide at least one output signal based on the differential signal pair. In another embodiment, configuration logic is operable to select between a first mode and a second mode of the transceiver circuit. The first mode includes the current mirror circuitry being disabled from providing a current signal to the output stage, and a first circuit path being closed to provide voltage to the output stage. The second mode includes the first circuit path being open and the current mirror circuitry being enabled to provide a current signal to the output stage.Type: GrantFiled: December 20, 2013Date of Patent: October 10, 2017Assignee: Intel CorporationInventors: Miaobin Gao, Christine M.

Patent number: 9608733Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical apparatus to control optical power of the light source. In one embodiment, the apparatus may include a transmitter and receiver to transmit and receive optical signals over an optical communication channel, and a controller to cause the transmitter to transmit pulse signals at a first power level and detect a change in optical power in the channel, indicating a presence of a signal from another optical apparatus. The controller may confirm that the detected apparatus is capable of communications at a second power level (greater than the first level) and initiate data transmission at the second level. Upon detection of a failure in the channel, the controller may cause the transmitter to halt the data transmission and restart the pulse signals at the first power level. Other embodiments may be described and/or claimed.Type: GrantFiled: June 9, 2014Date of Patent: March 28, 2017Assignee: Intel CorporationInventors: Chris Pavlas, Guobin Liu, Maciej Machnikowski, Christine M.

Patent number: 8938164Abstract: A system includes two optical modules that perform auto-setting of the optical links between the optical modules. One optical module sends an optical signal with a test pattern to the other optical module. If the receiving module determines that the test pattern is successfully received, it sends a pass indication to the transmitting module, and the transmitting module can configure its driver path in accordance with a transmit current setting used to transmit the test pattern. If the test pattern is not successfully received, the receiving module sends a fail indication, and the transmitting module can increase the transmit current setting and resend the test pattern. When the system includes multiple optical channels, one channel can be tested while feedback is provided on another channel. The system can iterate through all optical channels until they are all configured.Type: GrantFiled: September 28, 2012Date of Patent: January 20, 2015Assignee: Intel CorporationInventors: Miaobin Gao, Christine M.
