Abstract: Some examples of the present disclosure are related to a battery-charger reminder system. One example can include a battery charger with a wireless interface configured to transmit a wireless signal. The wireless signal can be used by a mobile device to determine a proximity of the battery charger to the mobile device. Another example can include a mobile device configured determine whether a distance between a battery charger and the mobile device exceeds a predefined threshold based on a wireless signal from the battery charger. If the mobile device determines that the distance exceeds the predefined threshold, the mobile device can generate a notification associated with the battery charger (e.g., to remind a user not to forget the battery charger).

Abstract: An adapter for an impact tool that securely holds a standard size socket. This adapter can be similar to a drill chuck and contain a locking mechanism to hold a socket. The adapter can be made to slip onto the impact tool just like any other tip or adapter. The adapter locks on the end of the impact tool. The socket receiving end resembles the mechanism of a standard socket wrench. Instead of the ball found on many socket wrenches, the present invention can contain a depressable pin with a tip that inserts into the socket. An edge on the pin provides positive protection against fall off even under extreme shock loads. The adapter can be supplied with different sized shanks to fit standard socket insert sizes. The adapter can optionally be used as an extension and manufactured in different lengths.
