A touch controller is disclosed. The touch controller can comprise sense circuitry configured to sense an object at a touch sensor panel, and a touch processor. The touch processor can be capable of, when the object is a first distance from the touch sensor panel, determining a predicted touch location associated with the object on the touch sensor panel based on at least a trajectory of the object towards the touch sensor panel, and when the object is a second distance from the touch sensor panel, less than the first distance, determining an identified touch location associated with the object on the touch sensor panel based on at least the predicted touch location.

Predictive touch detection

Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.

Using pulsed biases to represent DC bias for charging

Solid-state battery structures and methods of manufacturing solid-state batteries, such as thin-film batteries, are disclosed. More particularly, embodiments relate to solid-state batteries having an intermediate adhesive layer between several electrochemical cells. In an embodiment, an anode current collector at least partially fills a notch in a periphery of the intermediate adhesive layer. Other embodiments are also described and claimed.

Thin film battery assemblies

This application relates to a moisture ingress sensor. In particular, this application relates to a moisture ingress sensor that can detect liquid ingress into an electronic device. The moisture ingress sensor can include a resistor, an N-channel MOSFET, an operation amplifier, comparators, and an AND logic gate. The moisture ingress sensor is configured to provide a lower power means for accurately detecting moisture in an electronic device. Multiple areas of the electronic device can include the moisture ingress sensor in order to optimize the detection of moisture for at a variety of regions of the electronic device. Additionally, the electronic device can record signals from the moisture ingress sensor and shut down components of the electronic device that could be affected by the detected moisture. Furthermore, the moisture ingress sensor can be tuned to detect one or more types of liquids.

Moisture ingress sensors

Electronic devices may be accidentally exposed to liquid during operation. To detect liquid intrusion events, an electronic device may be provided with one or more electronic liquid contact sensors. The liquid contact sensors may have electrodes. Control circuitry may make measurements across the electrodes such as resistance and capacitance measurements to detect the presence of liquid. Liquid contact sensor data may be maintained in a log within storage in the electronic device. The liquid contact sensor data can be used to display information for a user of the electronic device or can be loaded onto external equipment for analysis. Liquid contact sensor electrodes may be formed from metal traces on substrates such as printed circuits, from contacts in a connector, from contacts on an integrated circuit, or from other conductive electrode structures.

Electronic device with liquid contact sensors

Techniques for mounting contacts of a connector are provided. One technique involves actively and continuously monitoring contacts being used and the contacts not being used in a connector in order to determine potential dendrite growth and/or potential corrosion due to liquid intrusion or the like. Another technique includes lowering a bias voltage on a power contact and performing a system detect prior to enabling operational voltage/current on the contact.

Techniques for monitoring contacts in a connector

Techniques for detecting mating and un-mating of a first connector with a second connector include providing a pulsed voltage signal at a contact of the second connector and measuring a rate of rise of voltage at the contact. If the measured voltage at the contact exceeds a threshold voltage during the time the pulsed voltage signal is applied, then it is concluded that the first connector is not present and not mated with the second connector. If the measured voltage is lower than or equal to the threshold voltage during the time of application of the voltage pulse, it is concluded that the first connector is present and mated with the second connector.
