Abstract: A method for monitoring battery degradation including receiving, from a pressure sensor, a first pressure value associated with a battery pack, comparing the first pressure reading to a first pressure threshold value and if the first pressure reading is greater than the first pressure threshold value, applying a first battery discharge pulse to the battery pack. The method further includes calculating a first internal resistance value of the battery pack in response to the first battery discharge pulse, comparing the first internal resistance value to an initial internal resistance value, and transmitting an alert to an electronic device if the first internal resistance value exceeds the initial internal resistance value.

Abstract: This application is directed to a battery protection system including a sense resistor, a comparator, a switching component, and a protection integrated circuit (PIC). The sense resistor is electrically coupled in series with one of a plurality of rechargeable battery cells that are coupled in parallel in a battery. The comparator is coupled to the sense resistor and configured to compare a voltage drop across the sense resistor with a reference voltage to determine whether a subset of the rechargeable battery cells is not charging in the battery. The switching component is coupled to the battery, while the PIC is coupled to the comparator and the switching component. The PIC is configured to control charging and discharging of the battery including disabling the battery from being charged in accordance with a determination that a subset of the rechargeable battery cells is not charging in the battery.

Abstract: Secure communication in mobile digital pages is provided. The system receives an electronic document and validates the electronic document for storage in a cache server. The system receives a request for the electronic document and provides it to a viewer component on a client computing device. The viewer component loads the electronic document in an iframe. The viewer component executes a runtime component to receive, via a secure communication channel, a tag from the electronic document. The system receives the tag and selects a data value for transmission to the viewer component. The viewer components provides the data value to cause the runtime component to execute an action with the data value.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for facilitating input by a user into a form. In one aspect, a method include actions of obtaining a web resource that includes a form, determining a particular field of the form has been selected, determining an intent that corresponds to the form from a first semantic tag in the web resource, determining a parameter of the intent that corresponds to the particular field of the form from a second semantic tag in the web resource, determining a value to suggest for the particular field based at least on the intent and the parameter of the intent, and providing the value for output as a suggestion of input for the particular field.
