Abstract: Phone reminder device (PRD) apparatus, systems, and methods for pairing with a protected phone include a processor, a memory unit that stores program instructions, a user input device, a Bluetooth low energy radio transceiver, an accelerometer, and an integral power source. PRD processor control routines, including visual feedback and customized auditory alerts, are based on selected modes of method and system operation, persistence of inferred or measured lack of proximity, history and frequency of alerts, current and historical PRD and/or phone movement, historical bases for lack of proximity, and loss of phone connection. User input or separate processor control adjust the transmission power level up with adjusted transmission power level in detecting protected phone proximity saved to the memory unit. Based on user input and PRD system and/or method dynamics, the memory unit maximizes integral power source life. PRD remote control of the protected phone camera application is disclosed.

Abstract: A brake rotor and brake drum stacking device, which is particularly useful for use in salvage yards and the like, comprises a unitary plastic member having a circular outer rim connected by means spaced-apart spokes with a holllow central hub. The hub is in the form of a stepped inverted cup, so that disc brake rotors have the disc surface supported by the spokes, with the studs and crown extending into hollow central hub. A sandwich arrangement of alternating stacking devices and disc brake rotors may be made, with the studs of the disc brake rotors supporting the next higher stacking device, with the crown of the rotor extending into the interior of the central hub. The dimensions of the stacking device permit a single sized stacking device to be used to stack disc brake rotors made by different manufacturers and used with vehicles of different sizes.
