Abstract: Eyewear having a sensor configured to sense electrical signals generated from user muscle movements to determine user facial expressions. The facial expressions are processed to provide a user input to the eyewear, to take an action such as taking an image using a camera, and to determine a user biometric such as by performing an electrocardiogram (ECG or EKG). In an example, a user can raise an eyebrow to instruct the eyewear to take an image and squint an eye to lighten/darken a shade of an optical element.

Abstract: A charging cable has a current sensor, a charging state indicator and logic circuitry to operate the indicator based on detected levels of current flow to a chargeable device. If the sensor detects current is below a low threshold, the logic circuitry operates the indicator to indicate that the cable is not connected to any chargeable device. If the sensor detects current at or above a higher threshold, the logic circuitry operates the indicator to provide a perceptible output indicating that the cable is connected to the chargeable device and the current is charging the battery. If the sensor detects current at or above the low threshold but below the high threshold, the logic circuitry operates the indicator to provide a perceptible output indicating that the cable is connected to a chargeable device but is not charging the battery of the device, e.g. when the battery is, or is nearly, fully charged.

Abstract: Eyewear that is configured to be wirelessly charged and also wirelessly communicate with a case charger having a battery using time gating power transfer. In one example, wireless charging and bidirectional communication of the eyewear can be performed using a unidirectional communication protocol, such as the Qi baseline power profile (BPP) which is only suited for unidirectional communication. The eyewear has a processor configured to send data to the wireless power charger that instructs the wireless power charger to stop wireless charging for a time period that is correlated to a state of charge (SOC) of the wireless power charger battery. The wireless power charger resumes charging of the eyewear battery after the time period, and the eyewear determines the SOC of the wireless power charger battery to be a percentage that correlates to the time period.

Abstract: A charging cable is configured to rotate freely while attached to a cable plug on a chargeable device. The plug has contact pads separated by an insulator, and the matching cable head has pins for contacting the pads of the plug. There may be a ‘deadzone’ position where one or more pins of the cable head rest of the separator and do not make contact with the charge pads on the cable plug. The examples include pins in the cable head for redundant charging paths that are complimentary such that only one of the power paths will be on at any given time.

Abstract: Eyewear that is configured to be wirelessly charged and also wirelessly communicate bidirectionally using a single coil in a front end. The single coil forms a single compact antenna that is configured for both near field data communications (NFC) and also for wireless charging when the eyewear is closely coupled to a wireless power charger having a transceiver. Wireless charging and bidirectional communication of the eyewear can be performed using Qi expanded power profile (EPP), which is an open interface standard developed by the Wireless Power Consortium.

Abstract: Eyewear including a see-through display, a battery, and a frame forming at least one electrical contact for connection to a battery charger for battery charging. The electrical contact is large compared to the size of a battery charging contact to allow easy alignment. The frame may be tied to ground in one example, and to a positive potential in another example. In another example, the frame may be formed into a left portion that is electrically isolated from a right portion. The left portion has a contact coupled to a ground electrode of the battery and is configured to connect to a ground electrode of the battery charger. The right portion has a contact coupled to a positive electrode of the battery and is configured to connect to a positive potential of the battery charger.

Abstract: A charging cable configured to obtain power from different power supply devices for delivery to a chargeable electronic device, and to techniques and equipment to enable the charging cable to identify current limitation of the connected power supply device and to enforce that current limit via the charging cable. The charging cable has a logic circuit coupled to signal pins to detect a signal indicating a power limitation of the power supply device. The logic circuit controls a current limiter connected in the power delivery bus of the charging cable to limit current flowing through the charging cable.
