Abstract: A robotic assistant comprises a plurality of sensors in a compact and unobtrusive form. One or more sensors may be emplaced upon a mast that may be selectively raised and lowered. The mast allows the robotic assistant to acquire images or other sensor data from a greater height, without substantially increasing the bulk of the robotic assistant. For ease of transport from one floor to another or from one building to another, the robotic assistant may deploy a handhold that a human may use to pick up and carry the robotic assistant. Floor characterization sensors may be used to determine characteristics of the floor such as if the floor is wet or dry. The robotic assistant may be used to provide a user with access to network services, to monitor a facility, provide telepresence services, and so forth.

Abstract: The time remaining until a charge-based event occurs on a computing device can be determined and notification provided to the user in order to prevent a shutdown due to loss of charge, extend the lifetime of the battery, and prevent a device lockout, among other such advantages. The current charge and information about the battery and device can be used to calculate various time periods, such as the time until a 0% state of charge (SOC) whereby a user will be unable to use the device until charging, as well as the time until a 0V lockout, whereby the device will become unusable. The time period and a charge-by date can be displayed on the device at the appropriate time(s), and notifications can be generated when the device is nearing a critical state. Such information also indicates to warehouses when devices become unsellable or at least require charging.
